Exam 2 Flashcards
Robert Yerkes
Began studying animals –> strengthened comparative psy.
William Small
Introduced rat maze
Mary Floy Washburn
Publises “The Animal Mind” (inferred mental state of animals)
Ivan Pavlov
Objective psy. and Watson’s research supported by Pavlov
James Loeb developed a theory of animal behavior based on the concept of:
Trophism: An involuntary forced movement (animal’s reaction to a stimulus is direct and automatic) Automatic processes do not require further explanation of consciousness
Thorndike’s law of..
Effect:REWARD more effective than mere repetition
Thorndike’s experimental approach to the study of association & instrument used to study it
Connectionsim: Learning as connections bw stimuli and responses // Puzzle box
Thorndike argued that behavior must be redued to which simplest elements?
Stimulus-Response units
Pavlov’s psychic reflexes AKA
conditioned reflexes: conditioned stimulus was a bell –> Salivating to the sight of food is learned (conditioned reflex)
Pavlov increased controlled environment in studies though?
The Tower of silence
Pavlov’s 3 areas of study
Function of the nerves of the heart, primary digestive glands, and conditioned reflexes
Contributions of Pavlov
Demonstrated study of higher mental processes in physiological terms
What school of thought was the direct antecedent of behaviorism
functionalism/ Watson studied under Angell
According to Watson, psychology was to be
the science of behavior
not the introspective study of consciousness
a purely objective, experimental natural science
use animals and humans as subjects
Psychology’s goal: The prediction and control of behavior
The method’s of behaviorism (2)
(objective methods) Verbal report: Talking is a behavior bc it is observable/ Conditioned reflex method: Watson’s substitute for introspection
Behaviorism’s popular appeal
Behaviorism’s popularity stemmed from from Watson’s emphasis on the nurturing effect of the childhood environment in determining behavior and minimization of the impact of inherited tendencies
Contribution’s of Watson’s Behaviorism (3)
Made psy. more objective in methods and terminology
Stimulated great deal of research
Objective methods and language became part of the mainstream
Neo-Behaviorism (4) (3 ppl)
(1930-1960) S-O-R bonds/ Focuses on learning/ Operationism/ Physics as guide of psy. //Tolman, Hull, and Skinner
Sociobehaviorism (4) (2 ppl)
(1960-1990) S-O-R bonds/ Cognitive processes are important to learning behavior/ NEW operationism –> operational definition// Increase objectivity of language and terminology// Bandura & Rotter
Operationism
We do not know the meaning of a concept unless we have a direct way of studying it bc A physical concept is the same as the set of operations or procedures by which it is determined
Bridgman (1927) The Logic of Modern Physics
Precise definition of all physical concepts/ concept= procedure by which it is determined// Concepts wo this must be discarded
Subject matter of behaviorism(3)
Instincts/ emotions/ OVERT BEHAVIOR
Watson’s views on instincts
Accepted them @ first, not later –> Denied inherited capacities, temperaments, talents –> increase popularity w/ American public
Watson’s views on emotions
Each emo.=specific configuration of physiological changes
Mary Jones
desensitized fears in infants (Peter & bunny)// EARLY CBT /Fear can be UNlearned
Watson: Emotions completely described 3 things
Objective stimulus situation
Overt bodily response
Internal physiological changes (visible vs not)
Criticisms of Watson’s Behaviorism
Many psychologist believed Watson’s program omitted important components such as sensory and perceptual processes
Karl Lashley’s 2 principles
Law of mass action: The efficiency of learning is a function of the total mass of cortical tissue//
Equipotentiality: The idea that one part of the cerebral cortex is essentially equal to another in its contribution to learning
William McDougall
Instinct theory claims that human behavior derives from innate tendencies
Tolman’s 3 contributions
Learning theory, intervening variables, purposive behaviorism
Purposive behaviorism
Tolman’s: objective study of behavior+Goal orientation in behavior.// Learning=tool to achieve goal/NO consciousnessORintrospection/ ONLY overt responses
Intervening variables
Unobserved&inferred factors within the organism that are the actual determinants of behavior (Ex: Hunger)
Tolman’s 5 IV as causes of behavior
environmental stimuli, psychological drives, heredity, previous training, and age
Tolman proposed that it was NOT S-R, instead
S-O-R (O=organism)
Tolman’s learning theory
Sign Gestalts: Proposed a cognitive explanation for learning(repeated performance of a task strengthens the learned relationship bw environmental cues and the O’s expectations
Tolman’s 2 contributions
Recognized as a forerunner of contemporary cognitive psychology /Popularized using rats in psychological research conducted by neobehaviorist and learning theorists from 1930-1960s
Hull’s grand theory
Hypothetico-deductive method: Establish postulates/ deduce experimentally testable hypothesis
Hull’s view on motivation
A state of bodily need that arises from a deviation from optimal biological conditions
Hull’s view on drives
Stimulus arising from a state of tissue need that arouses or activates behavior/Drive reduction is the only basis of reinforcement
Hull’s 4 useful methods for sci. research
observation, systematic controlled observation, experimental testing of hypothesis, and hypothetico-deductive method
2 drives according to Hull
Primary drives: food, water, air, temp regulation, defecation, urination sex, sleep Secondary drives (learning): Relate to situations or environmental stimuli associated with the reduction of primary drives and so may become drives themselves
Hull’s law of primary reinforcement
When a S-R relationship is followed by a reduction in a bodily need, the probability increases that on subsequent occasions the same stimulus will evoke the same response
Hull’s habit forming
The strength of the S-R connection which is a function of the number of reinforcements
Learning: Hull vs. Tolman
Emphasis on reinforcement characterizes Hull’s system as a need-reduction theory, as opposed to Tolman’s cognitive theory
Hull’s criticism
Lack of generalizability
Hull’s contributions(2)
influenced large number of psychologists and research/ & expounded the objective behaviorist approach to psychology
Hull vs Skinner
Hull emphasized the importance of theory, Skinner advocated an empirical system with no theoretical framework within which to conduct research
Skinner concerned with 3 subjects
Behavioral control/behavior mod/utopian society
Skinner was devoted to?
The study of RESPONSES and DESCRIBING behavior rather than explaining it
Skinner’s “empty organism approach”
S-R
Skinner’s experimental designs
n=1/ MANY trials
