TEST 2 (UNITS 5 - 7) Flashcards
any event or object in the environment to which an organism responds
STIMULUS
a relatively permanent change in behaviour, capability or attitude that is acquired through experience and cannot be attributed to illness, injury or maturation
LEARNING
a process through which a response previously made only to a specific stimulus is made to another stimulus that has been paired repeatedly with the original stimulus
CLASSICAL CONDITIONING
a stimulus that elicits a specific response without prior learning; eg. food
UNCONDITIONED STIMULUS
a response that is invariably elicited by the unconditioned stimulus without prior learning; eg. salivation in response to food
UNCONDITIONED RESPONSE
a neutral stimulus that, after repeated pairing with an unconditioned stimulus, becomes associated with it and elects a conditioned response; eg. the tone
CONDITIONED STIMULUS
a response that comes to be elicited by a conditioned stimulus as a result of its repeated pairing with an unconditioned stimulus; eg. salivation in response to the tone
CONDITIONED RESPONSE
DEFINITION: the weakening and often eventual disappearance of learned response, by repeated presentation of the conditioned stimulus without the unconditioned stimulus
EXAMPLE:
EXTINCTION
DEFINITION: the reappearance of an extinguished response (in a weaker form) when an organism is exposed to the original conditioned stimulus following a rest period.
EXAMPLE:
SPONTANEOUS RECOVERY
DEFINITION: in classical conditioning, the tendency to make a conditioned response to a stimulus that is similar to the original conditioned stimulus
EXAMPLE: a child attacked by a dog can easily develop a long-lasting fear of all dogs
GENERALIZATION
DEFINITION: the learned ability to distinguish between similar stimuli so that the conditioned response occurs only to the original conditioned stimulus but not to similar stimuli
EXAMPLE: this ability has survival value in that we know the difference between a rattlesnake and a garter snake
DISCRIMINATION
DEFINITION: occurs when a neutral stimulus is paired with an existing conditioned stimulus, becomes associated with it, and gains the power to elicit the same conditioned response
EXAMPLE: Suppose that after Pavlov conditioned the dogs to salivate to a tone, he presented a light (neutral stimulus) immediately before the tone a number of times. The light would become associated with the tone, and the dogs would learn to give the salivation response to the light alone.
higher-order conditioning
PRINCIPLE OF WHAT?
a type of learning in which the consequences of behaviour tend to modify that behaviour in the future (behaviour that is reinforced tends to be repeated; behaviour that is ignored or punished is less likely to be repeated).
OPERANT CONDITIONING
PRINCIPLE OF WHAT?
the consequences of behaviour are manipulated to increase or decrease the frequency of a response or to shape an entirely new response.
OPERANT CONDITIONING
DEFINITION: technique that reinforces any movement in the direction of the desired response, and gradually guiding the responses closer and closer to the ultimate goal
EXAMPLE: eg. Even though the B that Billy wrote looked more like a D, his teacher, Mrs. Chen, praised him because it was better than his previous attempts. Mrs. Chen is using a procedure called shaping.
SHAPING
POSITIVE OR NEGATIVE REINFORCEMENT?
a reward or pleasant consequence that follows a response and increases the probability that the response will be repeated
- eg. salary raises, promotions, awards, bonuses, good grades, and candy
POSITIVE
POSITIVE OR NEGATIVE REINFORCEMENT? the termination of an unpleasant stimulus after a response in order to increase the probability that the response will be repeated
- eg. turning on one’s air conditioner to terminate heat or getting out of bed to turn off a faucet to avoid listening to the annoying “drip, drip, drip.”
NEGATIVE
Differentiate between primary reinforcers and secondary reinforcers and examples of each kind
primary reinforcer: reinforcer that fulfills a basic physical need for survival and does not depend on learning; EG. food, water, sleep, sex, and the termination of pain
secondary reinforcer: neutral stimulus that becomes reinforcing after repeated pairing with other reinforcers; EG. attention from others is a powerful type of this reinforcer
4 factors that influence operant conditioning:
- magnitude of reinforcement
- immediacy of reinforcement
- level of motivation
- schedule of reinforcement
3 factors that influence the effectiveness of punishment
- timing of application
- intensity of application
- consistency of application
Compare and contrast classical and operant conditioning:
In classical conditioning, the focus is on what precedes the response. In operant conditioning, the focus is on what follows the response.
- Generally, in classical conditioning, the subject is passive and responds to the environment rather than acting upon it. In operant conditioning, the subject is active and operates on the environment.

3 PROCESSES INVOLVED IN THE ACT OF REMEMBERING
- ENCODING
- STORAGE
- RETRIEVAL
transforming information into a form that can be stored in short-term or long-term memory
ENCODING
the act of maintaining information in memory
STORAGE
the act of bringing to mind material that has been stored in memory
RETRIEVAL
As information comes in through our senses, virtually everything we see, hear, fee, or otherwise sense, is held in sensory memory but only for the briefest period of time.
Sensory memory normally holds visual images for a fraction of a second and holds sounds for about 2 seconds.
SENSORY MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
very limited capacity; short duration
SHORT-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
capacity is about 7 (plus or minus 2) different items or bits of information at one time
SHORT-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
used when we carry on a conversation, solve a problem or look up a telephone number and remember it just long enough to dial it.
SHORT-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
“Working memory”
SHORT-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
codes information according to sound and can also hold visual images, and store information in semantic form (i.e., according to meaning).
SHORT-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
stimulus tends to fade significantly after 20-30 seconds if it is not repeated.
SHORT-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
virtually unlimited capacity; long duration
LONG-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
no known limits to the storage capacity
LONG-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
holds all the knowledge we have accumulated, the skills we have acquired, and the memories of our past experiences
LONG-TERM MEMORY
SHORT-TERM OR LONG-TERM MEMORY?
the relatively permanent memory system with a virtually unlimited capacity
LONG-TERM MEMORY
EXPLAIN HOW DISPLACEMENT AND REHEARSAL AFFECT SHORT-TERM MEMORY
displacement: occurs when short-term memory is filled to capacity; each incoming item pushes out an existing item, which is then forgotten
2 main subsystems within long-term memory:
declarative memory and non-declarative memory
DECLARATIVE MEMORY or NON-DECLARATIVE MEMORY?
“explicit memory”; the subsystem within long-term memory that stores facts, information, and personal life experiences
DECLARATIVE MEMORY
DECLARATIVE MEMORY or NON-DECLARATIVE MEMORY?
“implicit memory”; the subsystem within long-term memory that consists of skills acquired through repetitive practice, habits and simple classically conditioned responses
NON-DECLARATIVE MEMORY
a single-memory system model in which retention depends on how deeply information is processed
LEVELS-OF-PROCESSING MODEL
6 CAUSES OF FORGETTING
- encoding failure
- consolidation failure
- decay theory
- interference
- motivated forgetting
- retrieval failure
CAUSE OF FORGETTING: forgetting resulting from material never having been put into long-term memory
ENCODING FAILURE
CAUSE OF FORGETTING: any disruption in the consolidation process that prevents a permanent memory from forming
CONSOLIDATION FAILURE
CAUSE OF FORGETTING: a theory of forgetting that holds that the memory trace, if not used, disappears with the passage of time
DECAY THEORY
CAUSE OF FORGETTING: the cause of memory loss that occurs when information or associations stored either before or after a given memory hinder our ability to remember it
INTERFERENCE
CAUSE OF FORGETTING: forgetting through suppression or repression in order to protect oneself from material that is too painful, anxiety-or-guilt-producing, or otherwise unpleasant
MOTIVATED FORGETTING
CAUSE OF FORGETTING: the type of forgetting where we are certain we know something but we are not able to retrieve the information when we need it
RETRIEVAL FAILURE
IDENTIFY SOME FACTORS THAT INFLUENCE THE RETRIEVAL OF INFORMATION
- we tend to recall information better if we are in the same internal state as when the information was encoded
- we tend to recall information better when we are in the same location - the same environmental context - as when the information was originally encoded
the tendency to recall information better if one is in the same pharmacological or psychological (mood) state as when the information was encoded.
state-dependent memory effect
4 STUDY HABITS THAT CAN AID MEMORY
- organization
- overlearning
- spaced vs. massed practice
- active learning vs. rereading
STUDY HABIT: organizing material to be learned is a tremendous aid to memory because we tend to retrieve information from long-term memory according to the way we have organized it for storage
ORGANIZATION
STUDY HABIT: practicing or studying material beyond the point where it can be repeated once without error
OVERLEARNING
STUDY HABIT: spacing studying over several different sessions generally is more effective than massed practice - learning in one long practice session without rest periods
SPACED VS. MASSED PRACTICE
STUDY HABIT: reading a paragraph and then practice recalling what you have just read - is much more effective than rereading
ACTIVE LEARNING VS. REREADING
an individual’s “ability to understand complex ideas, to adapt effectively to the environment, to learn from experience, to engage in various forms of reasoning, and to overcome obstacles by taking thought”
INTELLIGENCE
2 TYPES OF INTELLIGENCE:
- CRYSTALLIZED
2. FLUID
Verbal ability and accumulated knowledge.
CRYSTALLIZED INTELLIGENCE
Abstract reasoning and mental flexibility.
FLUID INTELLIGENCE
8 intelligences as outlined by Howard Gardner:
- Linguistic
- Logical-mathematical
- Spatial
- Bodily-kinesthetic
- Musical
- Interpersonal
- Intrapersonal
- Naturalistic
DESCRIBE BINET’S ROLE IN INTELLIGENCE TESTING
- published the intelligence scale
- Intelligence Scale was an immediate success in most Western countries
4 components of IQ test:
- Verbal Reasoning
- Quantitative reasoning
- Abstract visual reasoning
- Short-term memory
DISTINGUISH BETWEEN THE WECHSLER TEST FROM THE STANFORD-BINET TEST
- Wechsler test contains both verbal and performance subtests, which yield separate verbal and performance IQ scores as well as an overall IQ score.
- Wechsler test is a departure from the Stanford-Binet, which yields just one IQ score.
DISTINGUISH BETWEEN GROUP AND INDIVIDUAL INTELLIGENCE TESTS
individual intelligence tests: expensive, time consuming and administered to one individual at a time by a psychologist.
group intelligence tests: can be used when large numbers of people must be tested in a short period of time on a limited budget.
DESCRIBE THE PATTERN OF DISTRIBUTION OF IQ SCORES OBSERVED IN THE GENERAL POPULATION
- When large populations are measured on mental characteristics such as intelligence or on physical characteristics, the tests scores or results usually conform to the distribution known as the normal curve
- Most of the scores cluster around the mean (average). The farther the scores deviates, or move away, from the mean, above or below, the fewer people there are.

3 PROBLEM-SOLVING TECHNIQUES
- Trial and Error
- ALGORITHMS
- Heuristics
PROBLEM-SOLVING TECHNIQUE: occurs when we try one solution after another, in no particular order, until by chance we hit upon the answer
TRIAL AND ERROR
PROBLEM-SOLVING TECHNIQUE:
- Formulas used in mathematics and other sciences.
- The systematic exploration for every possible solution to a problem until the correct one is reached
- A computer, programmed to provide an accurate solution after millions of possible solutions were tried in a few seconds.
ALGORITHMS
PROBLEM-SOLVING TECHNIQUE:
* A problem-solving method that does not guarantee success, but offers a promising way to attack a problem and arrive at a solution.
HEURISTICS
EXPLAIN HOW MENTAL SET AND FUNCTIONAL FIXEDNESS BLOCK PROBLEM-SOLVING
Sometimes the difficulty in problem solving lies not with the problem but with ourselves. Not surprisingly, the same people who are subject to mental set are also more likely to have trouble with functional fixedness when they attempt to solve problems
DEFINITION:
- tendency to view an object in terms of its familiar usage is defined as:
- refers to our tendency to use techniques that worked in the past
MENTAL SET
DEFINITION: not consider using familiar objects in new and creative ways
FUNCTIONAL FIXEDNESS
EXPLAIN THE RELATIONSHIP OF CREATIVITY TO DIVERGENT THINKING
- creative thinkers are proficient in divergent thinking
- all creative thought is divergent, but not all divergent thought is creative .
Producing one or more possible ideas, answers, or solutions to a problem rather than a single, correct response.
DIVERGENT THINKING
can be thought of as the ability to produce original, appropriate, and valuable ideas and/or solutions to problems
CREATIVITY
