1954 Tanner and Swets proposed the application of signal detection theory to the study 
of thresholds。 
1957 S。 S。 Stevens demonstrated that changes in one’s subjective impression of stimulus 
magnitude are a power function of the actual stimulus magnitude。 
1957 Leo Hurvich and Dorothea Jameson; building on the earlier work of Ewald 
Hering; postulated the theory that color vision is based on opposing neural 
processes; the opponent…process theory of color vision。 
1959 David Hubel and Torsten Wiesel discovered that cells in the visual cortex of cats 
(and; in 1968; of monkeys) respond differentially to form and movement。

SUGGESTIONS FOR FURTHER READING 

Goldstone; R。 L。 (1995)。 Effects of Categorization on Color Perception。 Psychological Science; 6(5); 298— 

304。 Suggests that category learning influences the perceptual discrimination of color attributes。 
Provides empirical evidence that cognition influences perception by examining the influence of 
learned categorization on color perception。 
Kosslyn; S。 M。 (1995)。 Visual Cognition: An Invitation to Cognitive Science; Vol。 2 (2nd ed。)。 Cambridge: 
MIT Press。 Explores the mental aspects of visual processing。 Discusses the important research; 
discoveries; and insights in various areas of research on visual cognition and attempts to 
integrate work from related fields。 

Kosslyn; S。 M。; & Koenig; O。 (1992)。 Wet Mind: The New Cognitive Neuroscience。 An excellent volume 
that introduces the field of cognitive neuroscience to the uninitiated。 This volume covers a range 
of cognitive and neurological issues; to include sensation and perception。 Well written and easy 
for even the lay person to understand。 

Link; S。 (1994)。 Rediscovering the Past: Gustav Fechner and Signal Detection Theory。 Psychological Science; 
5(6); 335–340。 Suggests that the origins of experimental psychology are found in the theoretical 
works of Gustav Fechner and that Fechner is not given the credit that he is due for his 
contributions。 Argues that his works spawned many new ideas and theories; including the 
response bias found in signal detection theory。 

Matlin; M。 W。; & Foley; H。 J。 (1992)。 Sensation and Perception (3rd edition)。 Boston: Allyn and Bacon。 
A well…written introduction to the fields of sensation and perception。 

Meyering; T。 (1989)。 Historical Roots of Cognitive Science: The Rise of a Cognitive Theory of Perception 
from Antiquity to the Nineteenth Century。 Dordrecht: Kluwer Academic Publishers。 Begins with the 
Aristotelian theory of perception and then works its way to nineteenth century theories of 
perception。 A very thorough review of the history of perceptual theories。 

Sabourin; M。; Craik; F。; & Robert; M。 (1998)。 Advances in Psychological Science; Vol。 2: Biological and 
Cognitive Aspects。 Hove: Psychology Press/Eribaum (UK) Taylor & Francis。 Covers a wide range 
of topics in human and animal experimental psychobiology。 Provides an excellent review of 
current research in many areas of psychology including perception。 

Sekuler; R。 (1995)。 Motion Perception as a Partnership: Exogenous and Endogenous Contributions。 Current 
Directions in Psychological Science; 4(2); 43—47。 Describes the process of motion detection as a 
result of the interaction of exogenous and endogenous influences。

CHAPTER 5: PERCEPTION 

DISCOVERING PSYCHOLOGY 

PROGRAM 3: THE BEHAVING BRAIN 
Overview 

The structure and position of the brain: how neurons function; how information is collected and 
transmitted; and how chemical reactions determine every thought; feeling; and action。 

Key Issues 

The biology of the brain; how the brain processes information; the electroencephalogram (EEG); 
neurometric evaluation; the effects of drugs on the functions of the brain; the brain’s own manufactured 
chemicals; and neurotransplantation。 

Demonstrations 

Multiple brain wave recording to reveal various types of brain malfunction。
Effects of chemicals on learning and memory in rats。


New Interviews 

John Gabrieli illustrates how the brain stores and retrieves information。 

PROGRAM 7: SENSATION AND PERCEPTION 
Overview 

Explores how we make contact with the world outside our brain and body。 See how biological; 
cognitive; social; and environmental influences shape our personal sense of reality; and gain 
an understanding of how psychologists use perceptual errors to study how the constructive 
process of perception works。 

Key Issues 
Visual illusions; the biology of perception; the visual pathway; how the brain processes 
information during perception; sensory feedback in visual perception; and perceptual 
constancy。 

Demonstrations 
Sensory feedback in visual perception。 A Stanford student demonstrates the problems football 
quarterbacks face in the adjustment to special kinesthetic cues with distortion goggles that 
displace feedback from the perceived visual field。 

Perceptual constancy。 Philip Zimbardo demonstrates visual misperception in the Ames 
distorted room in the Exploratorium in San Francisco。 

Interviews 

Nobel Prize winner David Hubel explains the mapping of the reaction of receptor cells along 
the visual pathway of primates。 Hubel’s award…winning experiment of the response of neurons 
to electrical activity in the visual cortex of a cat illustrates his point。 

Misha Pavel uses puter graphics to demonstrate how the visual system of the brain breaks 
down and rebines visual stimulation into recognizable; coherent images。 

FILMS AND VIDEOS 

A Touch of Sensibility (1981)。 BBC; 50 minutes 

83 


PSYCHOLOGY AND LIFE 

This NOVA presentation discusses the importance of touch and the effects of touch deprivation。 
This film examines the importance of touch for development at various age levels。 Many interesting 
areas of research are cited。 

Brain Power (1983)。 IU (LCA); 11 minutes 

Discusses three principles of perception that affect how a person receives information: recognition; 
interpretation; and expectation。 Throughout the film; visual cues; puzzles; and optical illusions 
remind the viewer that one’s perceptions can be easily fooled。 A brief; clever film that stimulates 
students’ interest in sensation and perception。 

Human Perception: A Collection of Demonstrations and Effects (1986)。 Hanover; N。H。: 

Dartmouth College; Office of Instructional Services and Educational Research。 Contains real…time 
segments; single frames; picture and chapter stops。 

The Mind: Pain and Healing (1988)。 HARR; 24 minutes 

Reviews the influence of the mind on people’s ability to control pain and on their ability to promote 
physical healing。 An excellent film。 Traces the progress of a woman through a three…week clinic 
program to reduce chronic; long…term pain。 The changes in her movement and affect are dramatic。 
Demonstrates the placebo effect; and shows how cues; such as a doctor’s white coat; can trigger the 
release of endorphins to reduce pain。 In the final segment; a cancer patient discusses how the 
interaction of cognitive therapy with physical therapy has increased her life expectancy and her life 
quality。 

The Senses: Eyes and Ears (1985)。 FFHS; 26 minutes 

Visual and auditory distance receptors are discussed。 Demonstrations of how each processes 
information are also shown。 

The Senses: Skin Deep (1985)。 FFHS; 26 minutes 

The sense receptors that depend on immediate contact with the world—taste buds; olfactory cells; 
and touch sensors—are examined。 

CASE STUDY LECTURE LAUNCHER 

One night in 1965; a United Airlines Boeing 727 started a steady descent to Chicago’s O’Hare 
Airport from an altitude of 22;000 feet。 Nineteen miles off the shore of Lake Michigan; the plane 
plunged into the lake。 One month later; also at night; an American Airlines Boeing 727; preparing 
to land at Kentucky’s Boone County Airport; followed the thread of the Ohio River toward the 
runway which began at the river’s steep south bank。 The plane failed to make the runway; and 
crashed into the bank; 12 feet below the runway。 One night in early 1966; an Al Nippon Airlines 
Boeing 727 headed to
