Measurement And Representation Of Sensations

Measurement and Representation of Sensations offers a glimpse into the most sophisticated current mathematical approaches to psychophysical problems. In this book, editors Hans Colonius and Ehtibar N. Dzhafarov, top scholars in the field, present a broad spectrum of innovative approaches and techniques to classical problems in psychophysics at different levels of stimulus complexity. The chapters emphasize rigorous mathematical constructions to define psychophysical concepts and relate them to observable phenomena. The techniques presented, both deterministic and probabilistic, are all original and recent. Subjects addressed throughout the six chapters of this volume include: *computing subjective distances from discriminability; *a new psychophysical theory of intensity judgments; *computing subjective distances from two discriminability functions; *an alternative to the model-building approach based on observable probabilities; and *possible forms of perceptual separability developed within a generalization of General Recognition Theory. Measurement and Representation of Sensations is a valuable text for both behavioral scientists and applied mathematicians.

The publication in 1957 of S.S. Stevens' famous paper, On the psychophysical law, ignited a controversy which has continued ever since relating to people's subjective judgements of physical reality. Why is it that the perception of sensation can diverge so sharply from the magnitude of thestimulus? How should sensation be measured? Donald Laming brings together a diversity of ideas and a wealth of experimental evidence, and provides a challenging new perspective on the question which has fragmented the research community for nearly 40 years.

An engrossing history of the century that transformed our knowledge of the body’s inner senses The years between 1833 and 1945 fundamentally transformed science’s understanding of the body’s inner senses, revolutionizing fields like philosophy, the social sciences, and cognitive science. In How We Became Sensorimotor, Mark Paterson provides a systematic account of this transformative period, while also demonstrating its substantial implications for current explorations into phenomenology, embodied consciousness, the extended mind, and theories of the sensorimotor, the body, and embodiment. Each chapter of How We Became Sensorimotor takes a particular sense and historicizes its formation by means of recent scientific studies, case studies, or coverage in the media. Ranging among a diverse array of sensations, including balance, fatigue, pain, the “muscle sense,” and what Maurice Merleau-Ponty termed “motricity,” Paterson’s analysis moves outward from the familiar confines of the laboratory to those of the industrial world and even to wild animals and their habitats. He uncovers important stories, such as how forgotten pain-measurement schemes transformed criminology, or how Penfield’s outmoded concepts of the sensory and motor homunculi of the brain still mar psychology textbooks. Complete with original archival research featuring illustrations and correspondence, How We Became Sensorimotor shows how the shifting and sometimes contested historical background to our understandings of the senses are being extended even today.

Excerpt from The Time of Perception as a Measure of Differences in Sensations Whipple,2 in his study Of the discrimination of clangs and tones, took account of the relation of the speed Of judgment to certainty and correctness Of judgment as well as the relation Of speed and immediacy to correctness. The judgments fell into at most four categories as to speed, introspectively noted. The immediate judgments were found to be usually both correct and certain, while compared judgments were more Often uncertain and incorrect. Angeli,3 in a study of discrimination of shades of gray for different intervals of time, measured to tenths Of a second the time of delivering the discriminative judgment. The times were determined for the four categories of judgment, 'sure, ' 'fairly sure, ' 'like' and 'doubtful, ' for the four intervals of time 5, 15, 30 and 60 seconds. The results showed that 'like' judgments are longest, 'sure' judgments shortest, with 'fairly sure intermediate. This historical summary of the applications of the method indicates that the method has been used systematically in but two investiga tions and that these are preliminary and concerned more with the method as such than with the measurement of differences in sensa tions. The present research, it is believed, gives not only certain positive results by the method, but also a definite confirmation Of its validity and value.
