Aesthetics of music
In the pre-modern tradition, the aesthetics of music or musical aesthetics explored the mathematical and cosmological dimensions of rhythmic and harmonic organization. In the eighteenth century, focus shifted to the experience of hearing music, the origin of this philosophic shift is sometimes attributed to Baumgarten in the 18th century, followed by Kant. Through their writing, the ancient term aesthetics, meaning sensory perception, in recent decades philosophers have tended to emphasize issues besides beauty and enjoyment. For example, musics capacity to express emotion has been a central issue, Aesthetics is a sub-discipline of philosophy. In the 20th century, important contributions to the aesthetics of music were made by Peter Kivy, Jerrold Levinson, Roger Scruton, many musicians, music critics, and other non-philosophers have contributed to the aesthetics of music. Hanslick and his partisans asserted that instrumental music is simply patterns of sound that do not communicate any emotions or images, harry Partch and some other musicologists, such as Kyle Gann, have studied and tried to popularize microtonal music and the usage of alternate musical scales.
Many modern composers like La Monte Young, Rhys Chatham and Glenn Branca paid much attention to a system of tuning called just intonation. Since ancient times, it has been thought that music has the ability to affect our emotions, the Ancient Greek philosopher Plato suggests in The Republic that music has a direct effect on the soul. Therefore, he proposes that in the regime, music would be closely regulated by the state. In the 18th century, music was considered so far outside the realm of theory that music was barely mentioned in William Hogarths treatise The Analysis of Beauty. He considered dance beautiful, but treated music important only insofar as it could provide the accompaniment for the dancers. However, by the end of the century, people began to distinguish the topic of music and its own beauty from music as part of a media, as in opera. Compared to the fine arts, it does not engage the understanding sufficiently. To display the combination of genius and taste that combines ideas and beauty, Kant thought that music must be combined with words, as in song and opera.
In the 19th century, the era of romanticism in music, some composers and critics argued that music should and could express ideas, emotions, or even a whole literary plot. Challenging Kants reservations about instrumental music, in 1813 E. T. A. Hoffman argued that music was fundamentally the art of instrumental composition, although the Romantic movement accepted the thesis that instrumental music has representational capacities, most did not support Schopenhauers linking of music and metaphysics. The mainstream consensus endorsed musics capacity to represent particular emotions and situations, in 1832, composer Robert Schumann stated that his piano work Papillons was intended as a musical representation of the final scene of a novel by Jean Paul, Flegeljahre. The thesis that the value of music is related to its function was vigorously countered by the formalism of Eduard Hanslick
Psychoacoustics is the scientific study of sound perception. More specifically, it is the branch of science studying the psychological and physiological responses associated with sound and it can be further categorized as a branch of psychophysics. Psychoacoustics received its name from a field within psychology—i. e, recognition science—which deals with all kinds of human perceptions. It is a field of many areas, including psychology, electronic engineering, biology, physiology. These nerve pulses travel to the brain where they are perceived, the inner ear, for example, does significant signal processing in converting sound waveforms into neural stimuli, so certain differences between waveforms may be imperceptible. Data compression techniques, such as MP3, make use of this fact, in addition, the ear has a nonlinear response to sounds of different intensity levels, this nonlinear response is called loudness. Telephone networks and audio noise reduction systems make use of this fact by nonlinearly compressing data samples before transmission, another effect of the ears nonlinear response is that sounds that are close in frequency produce phantom beat notes, or intermodulation distortion products.
The expression that one hears what one wants to hear may pertain in such discussions, the human ear can nominally hear sounds in the range 20 Hz to 20,000 Hz. The upper limit tends to decrease with age, most adults are unable to hear above 16 kHz, the lowest frequency that has been identified as a musical tone is 12 Hz under ideal laboratory conditions. Tones between 4 and 16 Hz can be perceived via the sense of touch. Frequency resolution of the ear is 3.6 Hz within the octave of 1000 –2000 Hz and that is, changes in pitch larger than 3.6 Hz can be perceived in a clinical setting. However, even smaller pitch differences can be perceived through other means, for example, the interference of two pitches can often be heard as a repetitive variation in volume of the tone. This amplitude modulation occurs with a equal to the difference in frequencies of the two tones and is known as beating. The semitone scale used in Western musical notation is not a frequency scale. The intensity range of sounds is enormous.
Human ear drums are sensitive to variations in the sound pressure, for this reason, sound pressure level is measured logarithmically, with all pressures referenced to 20 µPa. The lower limit of audibility is defined as 0 dB. The upper limit is more a question of the limit where the ear will be harmed or with the potential to cause noise-induced hearing loss
Illusory continuity of tones
The illusory continuity of tones is the auditory illusion caused when a tone is interrupted for a short time, during which a narrow band of noise is played. The noise does, have to be of a high level to effectively mask the gap. Whether the tone is of constant, rising or decreasing pitch, most probably, this happens because of the way that the human ear adapted to filter out the background noise from signals in order to show one signal disturbed by noise as one event, not several. Illusory continuity is antagonistic with illusory discontinuity, while illusory continuity restores perceptual continuity of obscured sounds, illusory discontinuity disrupts the perception even if the sound is indeed continuous. Listeners strongly susceptible to illusory discontinuity do not perceive illusory auditory continuity, warren RM, Wrightson JM, Puretz J. Illusory continuity of tonal and infratonal periodic sounds.

Pragmatism is a philosophical tradition that began in the United States around 1870. Charles Sanders Peirce, generally considered to be its founder, described it in his pragmatic maxim, your conception of those effects is the whole of your conception of the object. Pragmatism rejects the idea that the function of thought is to describe, instead, pragmatists consider thought an instrument or tool for prediction, problem solving and action. The philosophy of pragmatism “emphasizes the practical application of ideas by acting on them to actually test them in human experiences”, Pragmatism focuses on a “changing universe rather than an unchanging one as the Idealists and Thomists had claimed”. Pragmatism as a movement began in the United States in the 1870s. Charles Sanders Peirce is given credit for its development, along with twentieth century contributors, William James and its direction was determined by The Metaphysical Club members Charles Sanders Peirce, William James, and Chauncey Wright, as well as John Dewey and George Herbert Mead.
The first use in print of the name pragmatism was in 1898 by James, James regarded Peirces 1877–8 Illustrations of the Logic of Science series as the foundation of pragmatism. Peirce wrote that from this definition, pragmatism is scarce more than a corollary, your conception of those effects is the whole of your conception of the object, which he called the pragmatic maxim. It equates any conception of an object to the extent of the conceivable implications for informed practice of that objects effects. Peirce lectured and further wrote on pragmatism to make clear his own interpretation, yet in a 1906 manuscript he cited as causes his differences with James and Schiller. And, in a 1908 publication, his differences with James as well as literary author Giovanni Papini. Peirce in any case regarded his views that truth is immutable and infinity is real, as being opposed by the other pragmatists, Pragmatism enjoyed renewed attention after Willard Van Orman Quine and Wilfrid Sellars used a revised pragmatism to criticize logical positivism in the 1960s.
Contemporary pragmatism may be divided into a strict analytic tradition and a neo-classical pragmatism that adheres to the work of Peirce, James. W. F. Hegel who introduced temporality into philosophy J. S. Metaphysics, not to be confused with pragmatics, a sub-field of linguistics with no relation to philosophical pragmatism. Additionally, forms of empiricism, verificationism, and a Quinean naturalist metaphilosophy are all elements of pragmatist philosophies. This causes metaphysical and conceptual confusion, from the outset, pragmatists wanted to reform philosophy and bring it more in line with the scientific method as they understood it. They argued that idealist and realist philosophy had a tendency to present human knowledge as something beyond what science could grasp and they held that these philosophies resorted either to a phenomenology inspired by Kant or to correspondence theories of knowledge and truth. Pragmatists criticized the former for its a priorism, and the latter because it takes correspondence as an unanalyzable fact, Pragmatism instead tries to explain the relation between knower and known
Eye movement in music reading
Eye movement in music reading is the scanning of a musical score by a musicians eyes. This usually occurs as the music is read during performance, although musicians sometimes scan music silently to study it, the phenomenon has been studied by researchers from a range of backgrounds, including cognitive psychology and music education. A central aspect of reading is the sequence of alternating saccades and fixations. Saccades are the rapid ‘flicks’ that move the eyes from location to location over a music score, saccades are separated from each other by fixations, during which the eyes are relatively stationary on the page. It is well established that the perception of information occurs almost entirely during fixations. Fixations comprise about 90% of music reading time, typically averaging 250–400 ms in duration, despite some 30 studies in this area over the past 70 years, little is known about the underlying patterns of eye movement in music reading. However, it is here that the similarities end.
It is this uniquely strict temporal requirement in musical performance that has made the observation of eye movement in music reading fraught with more difficulty than that in language reading, another critical difference between reading music and reading language is the role of skill. Most people become reasonably efficient at language reading by adulthood, even though almost all language reading is sight reading, by contrast, some musicians regard themselves as poor sight readers of music even after years of study. It is therefore unsurprising that most research into eye movement in reading has aimed to compare the eye movement patterns of the skilled. From the start, there were problems with eye-tracking equipment. The five earliest studies used photographic techniques and these systems were sensitive to even small movement of the head or body, which appear to have significantly contaminated the data. In addition to head movement, researchers faced other physical. The musculoskeletal response required to play a musical instrument involves substantial body movement, usually of the hands and this can upset the delicate balance of tracking equipment and confound the registration of data.
The disadvantage of this behaviour is that it causes signal dropout in the data every time it occurs, when participants are prevented from looking down at their hands, typically the quality of their performance is degraded. Rayner & Pollatsek wrote that, even skilled musicians naturally look at their hands at times, accurate eye movement recording these head movements. Musicians often need appreciable training with the apparatus before their eye movements can be measured, since Lang, all reported studies into eye movement in music reading, aside from Smith, appear to have used infrared tracking technology. However, research into the field has mostly been conducted using less than optimal equipment and this has had a pervasive negative impact on almost all research up until a few recent studies
Culture in music cognition
Culture in music cognition refers to the impact that a persons culture has on their music cognition, including their preferences, emotion recognition, and musical memory. Additionally, individuals musical memory abilities are greater for culturally familiar music than for culturally unfamiliar music, the sum of these effects makes culture a powerful influence in music cognition. Culturally bound preferences and familiarity for music begin in infancy and continue through adolescence, people tend to prefer and remember music from their own cultural tradition. Familiarity for culturally regular meter styles is already in place for young infants of only a few months age. The looking times of 4- to 8-month old Western infants indicate that they prefer Western meter in music, both groups preferred either meter when compared with arbitrary meter. In addition to influencing preference for meter, culture affects peoples ability to correctly identify music styles, adolescents from Singapore and the UK rated familiarity and preference for excerpts of Chinese and Indian music styles.
Neither group demonstrated a preference for the Indian music samples, although the Singaporean teenagers recognized them, an individuals musical experience may affect how they formulate preferences for music from their own culture and other cultures. American and Japanese individuals both indicated preference for Western music, but Japanese individuals were more receptive to Eastern music, among the participants, there was one group with little musical experience and one group that had received supplemental musical experience in their lifetimes. Bimusicalism is a phenomenon in which people well-versed and familiar with music from two different cultures exhibit dual sensitivity to both genres of music. In contrast, the Western and Indian participants more successfully recognized music from their own culture and these results indicate that everyday exposure to music from both cultures can result in cognitive sensitivity to music styles from those cultures. Bilingualism typically confers specific preferences for the language of lyrics in a song, Spanish speakers identified most closely with the Spanish song.
Thus, the language of lyrics interacts with a listeners culture, the cue-redundancy model of emotion recognition in music differentiates between universal, structural auditory cues and culturally bound, learned auditory cues. Structural cues that span all musical traditions include such as pace, loudness. Fast tempo, for example, is associated with happiness, regardless of a listeners cultural background. Culture-specific cues rely on knowledge of the conventions in a musical tradition. A particular timbre may be interpreted to reflect one emotion by Western listeners, according to the cue-redundancy model, individuals exposed to music from their own cultural tradition utilize both psychophysical and culturally bound cues in identifying emotionality. Conversely, perception of intended emotion in unfamiliar music relies solely on universal, psychophysical properties, Japanese listeners accurately categorize angry and happy musical excerpts from familiar traditions and relatively unfamiliar traditions.
Simple, fast melodies receive joyful ratings from these participants, slow samples receive sad ratings, strong relationships between emotional judgments and structural acoustic cues suggest the importance of universal musical properties in categorizing unfamiliar music
The octave illusion is an auditory illusion discovered by Diana Deutsch in 1973. It is produced when two tones that are an octave apart are repeatedly played in alternation through stereo headphones, the same sequence is played to both ears simultaneously, however when the right ear receives the high tone, the left ear receives the low tone, and conversely. Instead of hearing two alternating pitches, most subjects instead hear a tone that alternates between ears while at the same time its pitch alternates between high and low. The two tones used were pitched at 400 Hz and 800 Hz, corresponding roughly to G4, each tone was played for 250 ms before switching ears. No gaps were allowed between tones, both tones were therefore always present during the experiment, only the ears perceiving the high and the low tone at any one time changed repeatedly. After the initial test, the headphones were reversed, and the test was repeated,86 subjects were tested, and none perceived the tonal pattern correctly.
Most subjects heard a tone that alternated in pitch by an octave as it alternated between ears. When the earphones were reversed, the ear that initially heard the high tone continued to hear the tone. Some subjects only heard a tone that moved between ears but did not change in pitch, or changed very slightly. Several subjects heard various complex illusions, such as two alternating pitches in one ear and a pitch that sporadically occurred in the other ear. Handedness played an important role in the results, 58% of right-handed subjects and 52% of left-handed subjects heard a single pitch that switched between octaves as it switched between ears. Of the remaining subjects, nearly three times as many right-handers than left-handers heard a tone that switched ears but not pitch, Deutsch proposed that when a single tone that alternates between octaves is heard, this illusion results from the combined operation of two decision mechanisms. First, to determine the location, high pitches are given precedence, second, to determine the tones pitch.
This is known as the model, since it is proposed that the operation of two separate what and where decision mechanisms combine to produce the illusion. In a further experiment, Deutsch examined the effect of handedness, the subjects were 250 students, who were classified both according to their handedness and according to whether they had a left-handed parent or sibling. It was found that right-handers were more likely to hear the tone on the right than were mixed-handers. In another experiment and Roll explored the two-channel model in further detail and they played 44 right-handed subjects a repeating pattern of tones pitched at 400 Hz and 800 Hz. This time the ear was given three 800 Hz pitches alternating with two 400 Hz pitches, while the left ear simultaneously heard three 400 Hz pitches alternating with two 800 Hz pitches
Music and emotion
The study of music and emotion seeks to understand the psychological relationship between human affect and music. The field draws upon and has significant implications for areas as philosophy, music theory and aesthetics, as well the acts of musical composition. Two of the most influential philosophers in the aesthetics of music are Stephen Davies, Davies terms his concept the expressiveness of emotions in music appearance emotionalism, which holds that music expresses emotion without feeling it. Objects can convey emotion because their structures can contain certain characteristics that resemble emotional expression, the resemblance that counts most for musics expressiveness. is between musics temporally unfolding dynamic structure and configurations of human behaviour associated with the expression of emotion. The observer can note emotions from the posture, gestures, attitude. Associations between musical features and emotion differ among individuals, appearance emotionalism claims many listeners perceiving associations constitutes the expressiveness of music.
Which musical features are commonly associated with which emotions is part of music psychology. Davies claims that expressiveness is a property of music and not subjective in the sense of being projected into the music by the listener. Musics expressiveness is certainly response-dependent, i. e. it is realized in the listeners judgement, the philosopher Jenefer Robinson assumes the existence of a mutual dependence between cognition and elicitation in her description of emotions as process, music as process theory. This series of events continually exchanges with new, incoming information and these simultaneous musical processes can reinforce or conflict with each other and thus express the way one emotion morphs into another over time. The ability to perceive emotion in music is said to develop early in childhood, the capacity to perceive emotion in music is subject to cultural influences, and both similarities and differences in emotion perception have been observed in cross-cultural studies.
Empirical research has looked at which emotions can be conveyed as well as what structural factors in music help contribute to the emotional expression. There are two schools of thought on how we interpret emotion in music, the cognitivists approach argues that music simply displays an emotion, but does not allow for the personal experience of emotion in the listener. Emotivists argue that music elicits real emotional responses in the listener, segmental features are the individual sounds or tones that make up the music, this includes acoustic structures such as duration and pitch. Suprasegmental features are the structures of a piece, such as melody, tempo. There are a number of musical features that are highly associated with particular emotions. Performance features refers to the manner in which a piece of music is executed by the performer and these are broken into two categories, performer skills and performer state. Performer skills are the ability and appearance of the performer, including physical appearance, reputation
Aaron Copland was an American composer, composition teacher, and a conductor of his own and other American music. Copland was referred to by his peers and critics as the Dean of American Composers, the open, slowly changing harmonies in much of his music are typical of what many people consider to be the sound of American music, evoking the vast American landscape and pioneer spirit. He is best known for the works he wrote in the 1930s and 1940s in an accessible style often referred to as populist. Works in this include the ballets Appalachian Spring, Billy the Kid and Rodeo, his Fanfare for the Common Man. In addition to his ballets and orchestral works, he produced music in other genres including chamber music, vocal works, opera. After some initial studies with composer Rubin Goldmark, Copland traveled to Paris and he studied three years with Boulanger, whose eclectic approach to music inspired his own broad taste. Determined upon his return to the U. S. to make his way as a composer, Copland gave lecture-recitals, wrote works on commission.
He found composing orchestral music in the modernist style he had adapted abroad a financially contradictory approach and he shifted in the mid-1930s to a more accessible musical style which mirrored the German idea of Gebrauchsmusik, music that could serve utilitarian and artistic purposes. During the Depression years, he traveled extensively to Europe, during the late 1940s, Copland became aware that Stravinsky and other fellow composers had begun to study Arnold Schoenbergs use of twelve-tone techniques. After he had exposed to the works of French composer Pierre Boulez, he incorporated serial techniques into his Piano Quartet, Piano Fantasy, Connotations for orchestra. From the 1960s onward, Coplands activities turned more from composing to conducting and he became a frequent guest conductor of orchestras in the U. S. and the UK and made a series of recordings of his music, primarily for Columbia Records. Aaron Copland was born in Brooklyn, New York, on November 14,1900 and he was the youngest of five children in a Conservative Jewish family of Lithuanian origins.
While emigrating from Russia to the United States, Coplands father, Harris Morris Copland, Copland was however unaware until late in his life that the family name had been Kaplan, and his parents never told him this. His father was a staunch Democrat, the family members were active in Congregation Baith Israel Anshei Emes, where Aaron celebrated his Bar Mitzvah. Not especially athletic, the young man became an avid reader. Coplands father had no musical interest and his mother, Sarah Mittenthal Copland, played the piano, and arranged for music lessons for her children. Of his siblings, oldest brother Ralph was the most advanced musically and his sister Laurine had the strongest connection with Aaron, she gave him his first piano lessons, promoted his musical education, and supported him in his musical career. A student at the Metropolitan Opera School and a frequent opera-goer, Copland attended Boys High School and in the summer went to various camps
Dance is a performance art form consisting of purposefully selected sequences of human movement. This movement has aesthetic and symbolic value, and is acknowledged as dance by performers and observers within a particular culture, Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin. Other forms of movement are sometimes said to have a dance-like quality, including martial arts, figure skating, synchronized swimming. Theatrical dance, called performance or concert dance, is intended primarily as a spectacle and it often tells a story, perhaps using mime and scenery, or else it may simply interpret the musical accompaniment, which is often specially composed. Examples are western ballet and modern dance, Classical Indian dance and Chinese and Japanese song, most classical forms are centred upon dance alone, but performance dance may appear in opera and other forms of musical theatre. Such dance seldom has any narrative, a group dance and a corps de ballet, a social partner dance and a pas de deux, differ profoundly.
Even a solo dance may be solely for the satisfaction of the dancer. On the other hand, some cultures lay down strict rules as to the dances in which, for example. Archeological evidence for early dance includes 9, 000-year-old paintings in India at the Rock Shelters of Bhimbetka and it has been proposed that before the invention of written languages, dance was an important part of the oral and performance methods of passing stories down from generation to generation. The use of dance in trance states and healing rituals is thought to have been another early factor in the social development of dance. References to dance can be found in very early recorded history, Greek dance is referred to by Plato, Plutarch, the Bible and Talmud refer to many events related to dance, and contain over 30 different dance terms. In Chinese pottery as early as the Neolithic period, groups of people are depicted dancing in a line holding hands, Dance is further described in the Lüshi Chunqiu. Primitive dance in ancient China was associated with sorcery and shamanic rituals, during the first millennium BCE in India, many texts were composed which attempted to codify aspects of daily life.
Bharata Munis Natyashastra is one of the earlier texts and it mainly deals with drama, in which dance plays an important part in Indian culture. It categorizes dance into four types - secular, abstract, the text elaborates various hand-gestures and classifies movements of the various limbs, steps and so on. A strong continuous tradition of dance has since continued in India, through to modern times, where it continues to play a role in culture, and, the Bollywood entertainment industry. Many other contemporary dance forms can likewise be traced back to historical, ceremonial, Dance is generally, though not exclusively, performed with the accompaniment of music and may or may not be performed in time to such music. Some dance may provide its own audible accompaniment in place of music, many early forms of music and dance were created for each other and are frequently performed together
In music, gesture is any movement, either physical or mental. As such gesture includes both categories of movements required to sound and categories of perceptual moves associated with those gestures. The concept of musical gestures has received attention in various musicological disciplines in recent years. Thus gesture includes both characteristic physical movements by performers and characteristic melodies, chord progressions, and arpeggiations produced by those movements, in all cases, it is believed that musical gestures manifest the primordial role of human movement in music. Focusing on musical gestures provides a coherent and unifying perspective for a renewal of music theory, sound-accompanying, dance or other types of movements that are linked to music. Perceiver - movements that are a part of music listening, Directly connected, air performance Loosely connected. Grooving, tapping a foot, nodding the head, the first mathematical definition of gesture is given in the paper Formulas and Gestures in Music by Guerino Mazzola and Moreno Andreatta. A gesture is a configuration of curves in space and time, more formally, a gesture is a digraph morphism from a skeleton of addressed points to a body, a spatial digraph of a topological category.
Since the set of gestures of given skeleton and topological category defines a category, one may define gestures of gestures. Indian vocalists move their hands while improvising melody, although every vocalist has an idiosyncratic gestural style, the motion of the hand and voice are connected through various logics, and many students gesturally resemble their teachers. Nikki Moran, at the University of London, has done research on this topic, Clayton has published a paper on gestural interaction in Indian music performance, Time and Attention in a Khyal Performance. Robert Hatten has been using the concept of musical gestures to denote inner-musical qualities, the biological and cultural motivations of musical gesture are further negotiated within the conventions of a musical style, whose elements include both the discrete and the analog. Musical gestures are emergent gestalts that convey affective motion, pitch space Transformational theory Musical Gestures Group, University of Oslo Input devices and Music Interaction Laboratory, McGill University
Gestalt psychology or gestaltism is a philosophy of mind of the Berlin School of experimental psychology. Gestalt psychology is an attempt to understand the laws behind the ability to acquire, the central principle of gestalt psychology is that the mind forms a global whole with self-organizing tendencies. The assumed physiological mechanisms on which Gestalt theory rests are poorly defined, the Gestalt theory of perception has been criticized as being descriptive of the end products of perception without providing much insight into the processes that lead to perception. What happened to the Gestalt school that always aspired to provide a vision of psychology. Perhaps there is, in fact, little that holds the classic phenomena of Gestalt psychology together and this principle maintains that when the human mind forms a percept or gestalt, the whole has a reality of its own, independent of the parts. Koffka did not like the translation and he firmly corrected students who replaced other with greater.
This is not a principle of addition he said, the whole has an independent existence. In the study of perception, Gestalt psychologists stipulate that perceptions are the products of complex interactions among various stimuli, contrary to the behaviorist approach to focusing on stimulus and response, gestalt psychologists sought to understand the organization of cognitive processes. In psychology, gestaltism is often opposed to structuralism, Gestalt theory, it is proposed, allows for the deconstruction of the whole situation into its elements. The concept of gestalt was first introduced in philosophy and psychology in 1890 by Christian von Ehrenfels, the idea of gestalt has its roots in theories by David Hume, Johann Wolfgang von Goethe, Immanuel Kant, David Hartley, and Ernst Mach. On the philosophical foundations of these ideas see Foundations of Gestalt Theory and this gestalt or whole form approach sought to define principles of perception—seemingly innate mental laws that determined the way objects were perceived.
It is based on the here and now, and in the way things are seen, images can be divided into figure or ground. The question is what is perceived at first glance, the figure in front and these laws took several forms, such as the grouping of similar, or proximate, objects together, within this global process. The founders of Gestalt therapy and Laura Perls, had worked with Kurt Goldstein, Laura Perls had been a Gestalt psychologist before she became a psychoanalyst and before she began developing Gestalt therapy together with Fritz Perls. The extent to which Gestalt psychology influenced Gestalt therapy is disputed, in any case it is not identical with Gestalt psychology. Thus, though recognizing the historical connection and the influence, most gestalt psychologists emphasize that gestalt therapy is not a form of gestalt psychology and his work has no substantive relation to scientific Gestalt psychology. There are clinical applications of Gestalt psychology in the field, foremost in Europe.
The school of gestalt practiced a series of theoretical and methodological principles that attempted to redefine the approach to psychological research, principle of psychophysical isomorphism – A correlation exists between conscious experience and cerebral activity
