What is Cognition?
Cognitive Psychology
the scientific study of mental processes
Using controlled research methods to investigate questions of mind

Psychophysics Relates physical aspects of experience to
subjective experience
Important psychophysicists Fechner
Quantified relationships between incoming stimuli and resulting sensations
Psychology B.C.Psychophysics

c. 2008 Pearson Allyn & Bacon
Helmholtz Developed the notion of unconscious inference Three important insights about perception
Interpretive Influenced by previous experience Occurs outside of awareness
Psychology B.C.Psychophysics

Structuralism What is the structure of conscious experience?
Wundt, Titchener, introspection
Functionalism What are the functions of consciousness? Willam James emphasized the continuous nature
of consciousness
Psychology B.C.Structuralism and Functionalism

Behaviorism “mind” and “consciousness” are unobservable,
hence untestable
Only behavior should be the subject of study Behavior can be characterized completely by stimuli
and responses “Mind” is an impenetrable “black box”
Psychology B.C.Behaviorism
![Page 11: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/11.jpg)

Bartlett Investigated memory for stories Recall guided by “schemata”
Gestalt psychologists Investigated mind’s
organizational tendencies “whole is different than
the sum of its parts”

The Emergence of Cognitive PsychologyS-R Explanations: Seriously wRong? S-R view of learning
Learning as an S-R “chain” Critical components
Response Reinforcement
![Page 14: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/14.jpg)
c. 2008 Pearson Allyn & Bacon
The Emergence of Cognitive PsychologyS-R Explanations: Seriously wRong? Learning without responding
Response is part of what is learned Learning cannot occur in the absence of a
response
McNamara, Long, Wike (1956) found rats prevented from running a maze still learned
A “mental map” of the maze?
![Page 15: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/15.jpg)
c. 2008 Pearson Allyn & Bacon
The Emergence of Cognitive PsychologyS-R Explanations: Seriously wRong? Learning without reinforcement
Reinforcement necessary for solidifying S-R associations
Tolman and Honzik found learning in the absence of reinforcement
![Page 16: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/16.jpg)
c. 2008 Pearson Allyn & Bacon
The Emergence of Cognitive PsychologyS-R Explanations: Seriously wRong?
Tolman proposed “cognitive maps” to account for learning in the absence of response or reinforcement cognitive maps = mental representation Necessity of investigating “mind”
![Page 17: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/17.jpg)
c. 2008 Pearson Allyn & Bacon
The Emergence of Cognitive PsychologyS-R Explanations: Seriously wRong? Other criticisms of behaviorism
Lashley Skilled behavior is too complex for an S-R account
Chomsky Linguistic expression is too creative and
productive for an S-R account
![Page 18: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/18.jpg)
c. 2008 Pearson Allyn & Bacon
The Emergence of Cognitive PsychologyS-R Explanations: Seriously wRong? Technological influences on the development of
cognitive psychology Communication Systems
Computers
These sequential, information-processing systems provided a possible metaphor for mind
![Page 19: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/19.jpg)
c. 2008 Pearson Allyn & Bacon
Psychology after BehaviorismBehaviorism Reconsidered
Behaviorism had considerable influence
Rigor of research
Observations of behavior still central
![Page 20: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/20.jpg)
c. 2008 Pearson Allyn & Bacon
Psychology after BehaviorismInformation Processing: A Computer Metaphor
Information processing approach Models thinking on the computer Assumptions:
Humans as symbol manipulators Human thought as active, interpretive Processing is step-by-step; stages can be
isolated
![Page 21: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/21.jpg)
c. 2008 Pearson Allyn & Bacon
Psychology after BehaviorismConnectionism: A Brain Metaphor
Connectionist Approach Models thinking on neural networks Assumptions:
Cognitive processes occur in parallel Networks of neurons distributed throughout brain “parallel distributed processing”
![Page 22: C. 2008, Pearson Allyn & Bacon Introduction to Cognition Chapter 1](https://reader035.vdocument.in/reader035/viewer/2022081504/56649e425503460f94b35022/html5/thumbnails/22.jpg)
c. 2008 Pearson Allyn & Bacon
Psychology after BehaviorismAlternative Approaches
Criticisms of current conceptions of mind: Materialist critique: Is “mind” separable from
“brain”?
“Disembodied” approach to the study of mind Importance of studying cognition and action Importance of studying cognition in meaningful
contexts “ecological validity”
