Sensory neuroscience: fours laws of psychophysics Auteur(s) : ZWISLOCKI J.J. Date de parution: 11-2008 Langue : ANGLAIS 230p. Hardback

Sensory Neuroscience:Four Laws of Psychophysics examines both psychophysics, the science of relationships between human sensations, and the stimuli that evoke them. More specifically, it defines four multisensory relationships of great generality between sensation magnitudes and the underlying stimulus magnitudes. Although, psychophysics belongs to sensory neuroscience and is strongly coupled to neurophysiology, it also has branched out to various specialized academic fields, including the sciences of vision and hearing, ophthalmology, optometry, otology, and audiology. Due to this diversification and fragmentation psychophysics has had an ad-hoc, phenomenological orientation and, besides the Weber law of differential sensitivity, has lacked a systematic grid of scientific laws. Through contributions from distinguished researchers in this field, Sensory Neuroscience:Four Laws of Psychophysics, provides valid unifying principles and systematic applications to this otherwise fragmented precursor of experimental psychology. This book will be particularly useful to auditory researchers, behavioural neuroscientists, and experimental psychologists.

Psychophysics: A Practical Introduction (Hardcover) de Frederick A.A. Kingdom (Author), Nicolaas Prins (Author) Date de parution : 2009

Psychophysics is the primary scientific tool for understanding how the physical world of colors, sounds, odors, movements and shapes translates into the sensory world of sight, hearing, touch, taste and smell - in other words, how matter translates into mind. This book is the first to combine into a single volume the principles underlying the science of psychophysical measurement and the practical tools necessary to analyze data from psychophysical experiments. Written in a style that makes even the trickiest concepts and procedures accessible to the non-expert, this book is essential reading both for newcomers to the field as well as seasoned practitioners.
