6-Psychology-Cognition-Learning-Kinds

activity-dependent enhancement

Learning releases more vesicles from presynaptic terminals release than sensitization does {activity-dependent enhancement}. Calcium ion binds to calmodulin, and complex binds to and activates adenyl cyclase. Increased transmitted glutamate binds to ionotropic alpha-amino-3-hydroxy-5-methyl-4 isoxazole proprionic-acid receptor (AMPA receptor), which lets sodium ion in and potassium ion out. If action potentials increase, postsynaptic-membrane depolarization increases, and magnesium ions leave N-methyl-D-aspartate receptor (NMDA receptor) channels and go into intercellular space. NMDA receptors are glutamate-gated channels that can open with the artificial substance NMDA, which does not affect other glutamate-gated channels. The empty channel allows more sodium ion to enter, potassium ion to leave, and calcium ion to enter, and changes metabolism to make and send transmitter back to presynaptic terminal to make more action potentials.

conditioning

Fruitflies with mutations to proteins in this pathway cannot learn many classical conditioning tasks involving harmful stimuli, pleasant stimuli, and different responses. Mutants {dunce gene mutant} do not break down cAMP. Mutants {rutabaga mutant} can have little adenyl cyclase. Mutants {amnesiac mutant} do not make peptide transmitter that activates adenyl cyclase. Mutants {DCO mutant} can have altered cAMP-dependent protein-kinase-A catalytic subunits. Other mutants {cabbage mutant} {turnip mutant} can happen.

autoshaping

If stimulus precedes stimulus that causes behavior, first stimulus then causes the behavior {autoshaping}. Autoshaping is stimulus-stimulus response, as in classical conditioning.

blocking effect

If conditional stimulus pairs with reinforcer, and then second stimulus pairs with first stimulus and reinforcer, animals do not later respond to only second stimulus {blocking effect}. Low attention, little surprise, or looking for likely cause can cause blocking effect. However, cognition can prevent conjunctions from causing associations.

critical period

Learned associations can happen only at specific times {critical period}| {sensitive period} during development. Psychological processes can develop quickly over short times. For example, in the first year, children learn to trust other people. In preadolescence, delinquent behavior can begin.

eye-blink conditioning

Cerebellar cortex and interpositus nucleus store eye-blink conditioning {eye-blink conditioning}. Mossy-fiber input comes from pons and goes to granule cells, which send parallel fibers to Purkinje cells. Climbing-fiber input comes from dorsal accessory olivary nucleus and goes to Purkinje cells. Purkinje cells send to interpositus nucleus, which sends to superior cerebellar peduncle and then to red nucleus to perform conditioned response.

free recall

Learning tasks can use verbal-item lists. Recall can be in the same order {order recall} or any order {free recall}.

habit formation

Reward or reinforcement can be greater or smaller to change behavior {response-stimulus conditioning} {habit formation} [Watson, 1913] [Watson, 1924].

habit learning

In response to signal, people can unconsciously repeat mental tasks {habit learning}. Habit learning improves with practice. Habit learning involves activating neostriatum, caudate nucleus, putamen, and substantia nigra after learning. Neostriatum receives from sense and motor cortex and associates them. Substantia nigra and caudate nucleus have dopamine neurons. Perhaps, they are feedback channels for rewards.

Hebbian learning

If two inputs to one neuron are almost simultaneous {pairing}, either input later has larger effect on neuron than it did before {Hebbian learning}.

latent learning

Stimulus association can happen even with no reward {latent learning}. If animals can explore region before learning path to goal, learning is faster.

multiple discrimination learning

Mind can discriminate objects and events {multiple discrimination learning}, to understand scenes or situations.

observational learning

Learning {observational learning} {imitation learning} can use watching and copying. More imitation results if imitated person's prestige is high, if imitated person is similar to imitator, if rewards are more, and if responses are specific.

omission training

Omitting expected reward {omission training} changes behavior.

perceptual learning

Reading is a perceptual skill. Repeating perceptual discriminations in context {perceptual learning} unconsciously improves discriminations up to weeks later. Coordinating perception with action and adapting to new perceptions involve different learning than for concepts or conditioning.

factors

Discrimination depends on feature such as texture, motion direction, and line orientation, with no reward or feedback. Seemingly, people learn underlying rules.

transfer

No learning transfer goes to other locations, other brain parts, or similar objects.

comparisons

Besides perceptual learning, there is also language learning and social learning, such as imitation, modeling, and teaching.

principle learning

People can observe, manipulate, and analyze multiple examples, scenes, or situations to generalize and discriminate and to combine concepts to form principles or laws {principle learning}.

subliminal learning

Subliminal learning is not effective {subliminal learning}| [Merikle, 2000].

6-Psychology-Cognition-Learning-Kinds-Verbal

articulatory suppression

Articulating repeated simple linguistic units while hearing target items decreases memory {articulatory suppression}. Articulatory suppression causes no difference in memory with different vowel sound lengths.

discriminability

While learning two lists, people assign items to List1 or List2 and build concepts of List1 and List2 {list distinctiveness} {list differentiation} {discriminability}. More list repetitions make more discriminability.

distractor in learning

People can see target sequence, then see distractor sequence {distractor, learning}, and then take test. People remember the first trial perfectly, by semantic coding.

irrelevant speech

Simultaneously presented unrelated linguistic items {irrelevant speech} decreases memory.

mediated generalization

Children over five can use word that symbolizes category {mediated generalization} {learned generalization}. First, word overgeneralizes, and then word further discriminates.

nonsense syllable

Artificial syllables {nonsense syllable} have beginning and ending consonants and middle vowel. Consonant-vowel-consonant nonsense syllables can standardize material to learn. It can minimize affects of meaning, emotion, attention, imagery, and background knowledge. Nonsense syllables can prevent previous associations from affecting learning or memory [Ebbinghaus, 1913].

However, nonsense syllables are not equal in learning ease, because learners still try to match sound or symbol sequences to real words. People no longer use nonsense-syllable learning.

paired-associate learning

People can learn verbal-item-pair lists {paired-associate learning}. Later, learners hear or see the first item of pair, then recall second.

reading span task

Given a sentence sequence, subjects recall sentence meaning and last sentence word {reading span task}. Number of sentences recalled correctly is reading span, which correlates strongly with prose comprehension and short-term-memory information content, better than with word span or digit span.

suffix effect

Adding an independent verbal item with a new vowel sound, in any language or with no meaning, to series ends can decrease memory {suffix effect}. Other items do not affect memory.

6-Psychology-Cognition-Learning-Kinds-Skill

skill learning

People can unconsciously learn repeated motor procedure {skill, learning}| {motor skill} in response to instruction or will. Skill improves with practice.

brain

At skill-learning beginning, prefrontal cortex stores temporary information, parietal cortex is for attention, and cerebellum coordinates movements. Skill learning enlarges sensorimotor cortex. After learning, neostriatum caudate nucleus and putamen activity increases and prefrontal-cortex, parietal-cortex, and cerebellum activity decreases.

practice

Training and experience make behaviors more coordinated, nuanced, and unconscious. Practice develops efficient strategies. Improvement with practice is rapid at first and then is gradual but always continuing.

properties

Skill holds over many years. Interference from other learning, not decay over time, causes people to forget discrete motor skills over time.

performance strategy

Skill involves learning efficient chained action programs, from initiation to result {performance strategy}. Performance strategy involves perceptions, analyses, and responses. Practice develops efficient strategies.

sequence learning

People can unconsciously learn to perform movement sequence {sequence learning}. Such motor skill learning improves with practice.

6-Psychology-Cognition-Learning-Kinds-Concept

conceptual learning

Mind can form object or event idea {conceptual learning}, by deriving abstract ideas and rules from perception.

comparison

Conceptual learning differs from action learning, conditioning, language learning, and social learning, such as imitation, modeling, and teaching.

process

To form concept, mind uses example object or event and then generalizes. Mind does not use abstract statements.

Mind compares later perceptions to generalized example, using both denotations and connotations for identification, categorization, and discrimination.

process: combination

New concepts can combine existing-concept parts. Methods of combining ideas are type, token, argument, function, predication, and quantification.

referents

Concept categories are actions, amounts, events, objects, places, paths, properties, and states. Concept categories include subjects, verbs, adjectives, and other syntactic categories.

Concrete concepts are easiest to learn. Spatial concepts are next easiest to learn. Number concepts are hardest to learn [Dehaene, 1997].

relations

Concepts depend on shared place or time {locational concept}, stimulus part {analytic concept}, idea or attribute {categorical concept} {superordinate concept}, or relation {relational concept}.

Older children use fewer relational concepts and more categorical and analytic concepts.

Inferences can be associations.

truth

Truth is judgment about concepts in conceptual structure.

status

Concepts can have good or poor articulation.

validity

Person's concepts can match other people's concepts.

biology

All mammals can form concepts.

accessibility of concept

Concepts can be communicable and so useful for others {accessibility, concept}. Models or interpretations can allow people to know possible worlds.

activity theory

Object meaning depends on object actions, uses, movements, and interactions with other things {activity theory}. People develop meaning as they learn about motion types. Children learn how to move things and then build concepts of how things can move. Activities involve person's own movements and reactions and so are not merely symbolic.

cognitive unit

Cognition involves different levels {cognitive unit}. Image is first-level unit. Object or image symbol is second-level unit. Concept or class of symbols, objects, or images is third-level unit. Rule about concept relations is fourth-level unit.

conceptual well-formedness rule

Concepts have forms, connect to other concepts using rules {conceptual well-formedness rule}, and belong to categories. These properties allow concept learning.

gist

People have a meaningful visual-scene overview {gist}| [Biederman, 1972] [Hochstein and Ahissar, 2002] [Kreiman et al., 2000] [Mack and Rock, 1998] [Potter and Levy, 1969] [Wolfe and Bennett, 1997] [Wolfe, 1998] [Wolfe, 1999]. Perhaps, gist involves weak associations {proto-object} [Rensink, 2000]. Perhaps, gist involves weak associations {fringe consciousness} [Galin, 1997] [James, 1962].

ideation

People have thought formation process {ideation}|. New ideas combine existing-idea parts.

minimum sufficient causation

Animals seem to assume cognitive principle that effect requires cause {minimum sufficient causation}.

6-Psychology-Cognition-Learning-Kinds-Concept-Categorization

categorization

Mind can build object or event classes {categorization} {conceptualizing} {categorizing, learning} {category learning} and can apply verbal labels to objects or events. Categories have an overall concept.

categories

People typically use categories whose members have approximately same values for several independent attributes. People typically do not use categories based on relations between attributes. People typically do not use categories that have two member types, two relation types, or two attribute values.

Category members typically do not share necessary and sufficient attributes. Category members have many independent attributes, and members have different sets of values, with some values outside normal range. Different member pairs typically share different attribute values.

processes

Categorization can generalize several examples, combine existing categories, divide existing categories, or make analogies from existing categories to other objects or events. Learning generalizes unconsciously and consciously from specific objects, scenes, and situations to what they have in common, what is invariant, or what is similar. Perhaps, sensory cortex averages over examples.

processes: definition

To form category, propose category member, choose attribute, and use attribute value. For example, for bird, choose wing color, and use the color blue.

People typically do not define categories using non-member or opposite attribute value.

requirements

Categorization requires perceiving whole objects and their attributes or actions, understanding truth and falsehood, using reference and association, using words as symbols for things, knowing to which attributes people pay attention, and knowing what people already know.

development

Children first make semantic categories and then build grammatical categories.

equivalence category

Category items can be of same class {equivalence category} or be the same {identity category}. Items in equivalence category can have same attribute value or same attribute relations.

6-Psychology-Cognition-Learning-Kinds-Concept-Categorization-Strategy

conservative focusing

Find situation that makes one hypothesis true, find second situation that differs from first in only one way, and test hypothesis on second situation {conservative focusing}.

focus gambling

Find situation that matches one hypothesis, find any other situation, and test hypothesis on other situation {focus gambling}.

simultaneous scanning

For situations, test all hypotheses {simultaneous scanning}.

successive scanning

For hypotheses, test all situations {successive scanning}.

6-Psychology-Cognition-Learning-Kinds-Drive Reduction

drive reduction

Behavior that satisfies need reduces drive stimuli {drive reduction} and so causes reinforcement [Hull, 1940] [Hull, 1943].

need

Deviation from equilibrium {need, learning} causes drive stimuli. Needs are physiological {primary need} or psychological {secondary need} [Hull, 1940] [Hull, 1943].

6-Psychology-Cognition-Learning-Kinds-Effort

deliberate learning

People can try to memorize {deliberate learning}. Recall is worse for incidental learning than for deliberate learning.

incidental learning

Doing cognitive tasks strengthens cognitive processes and results in memory {incidental learning}. Recall is worse for incidental learning than for deliberate learning. People can learn just by observation, consciously but with no instructions how to learn or to what to attend and no reason to learn.

6-Psychology-Cognition-Learning-Kinds-Conditioning

conditioning in learning

Learning {conditioning, learning}| can be association between stimulus and response or response and reward.

theories

Main theories about conditioning are stimulus-stimulus (S-S), stimulus-response (S-R), and expectancy [Watson, 1913] [Watson, 1924].

factors

Animal drives, habits, and sensitivities affect conditioning.

factors: reward

Punishment intensity or reward intensity affects conditioning speed and effectiveness.

Conditioning can depend on reinforcement unexpectedness. Surprise is a cognitive act.

factors: stimulus

The stronger the conditioned stimulus, the greater the reflex {stimulus strength, conditioning}

effects

Only conditioning can alter autonomic nervous system, which controls heart rate and blood pressure. Conditioning can alter voluntary nervous system.

timing

Maximum interval for conditioning is 30 minutes, but 0.5 sec is best.

biology

Conditioning is in brains, not peripheral organs.

biology: animals

Classical and instrumental conditioning are similar in many species [Hull, 1940] [Hull, 1943].

awareness

Instrumental conditioning can reflect learning about relationship between action and reinforcement, rather than just unconsciously increasing reflex or habit frequency.

6-Psychology-Cognition-Learning-Kinds-Conditioning-Classical

classical conditioning

If unconditioned stimulus elicits response and stimulus pairs in space and time repeatedly with another stimulus, second conditioned stimulus elicits conditioned response {classical conditioning}| {signal learning} {Pavlovian conditioning}.

properties: rules

Conditioned stimulus must predict conditioned response {contingency, conditioning}. Conditioned stimulus must be close in time to unconditioned stimulus {temporal contiguity, conditioning}.

passivity

Conditioning does not depend on human or animal actions. Pavlovian conditioning is unconscious for reflexes, autonomic nervous system, and emotions.

extinction

If pairing ceases, conditioning decreases by extinction.

comparison: sensitization

Classical conditioning is stronger and longer than sensitization.

conditioned taste aversion

Classical conditioning can teach people to avoid taste {conditioned taste aversion}.

delay conditioning

For reflexes, classical conditioning can apply conditioned stimulus and then unconditioned stimulus, to cause conditioned response {delay conditioning} [Carrillo et al., 2000] [Carter et al., 2003] [Clark and Squire, 1998] [Clark and Squire, 1999] [Han et al., 2003] [Knuttinen et al., 2001] [Lovibond and Shanks, 2002] [Öhman and Soares, 1998] [Quinn et al., 2002].

fear conditioning

Shock, noise, or scary image {fear conditioning, learning} {conditioned fear} changes skin conductance or makes animal stand still. Putting animal in same location used for fear conditioning causes fear {context fear conditioning} [Quinn et al., 2002].

sensory preconditioning

In senses, when second stimulus follows first stimulus, second stimulus can pair with first stimulus {sensory preconditioning}. Second stimulus can cause the behavior that first stimulus causes. Sensory preconditioning is stimulus-stimulus classical conditioning.

trace conditioning

Classical conditioning can use conscious conditioned stimuli {trace conditioning}, which involve declarative memory [Carrillo et al., 2000] [Carter et al., 2003] [Clark and Squire, 1998] [Clark and Squire, 1999] [Han et al., 2003] [Knuttinen et al., 2001] [Lovibond and Shanks, 2002] [Öhman and Soares, 1998] [Quinn et al., 2002].

6-Psychology-Cognition-Learning-Kinds-Conditioning-Factors

conditioned response

After conditioning, conditioned stimuli elicit the same response {conditioned response} (CR) that unconditioned stimuli elicit.

conditioned stimulus

After conditioning, stimuli {conditioned stimulus} (CS), such as musical notes, that were neutral before conditioning elicit conditioned responses.

unconditioned stimulus

Stimuli {unconditioned stimulus} (US) can naturally elicit behavioral responses and can pair in space and time with conditioned stimuli.

activity dependence

Conditioned stimuli have an optimum interval, starting 0.2 to 1 second before unconditioned stimulus and ending when both stimuli stop simultaneously {activity dependence}.

6-Psychology-Cognition-Learning-Kinds-Conditioning-Rules

contingency conditioning

Conditioned stimuli must predict conditioned responses {contingency}.

temporal contiguity

Conditioned stimuli must be close in time to unconditioned stimuli {temporal contiguity, learning}.

6-Psychology-Cognition-Learning-Kinds-Conditioning-Instrumental

instrumental learning

If a stimulus elicits a response, and then organism gets a reward, response frequency to stimulus increases {instrumental learning}| {instrumental conditioning} {stimulus-response learning} {trial and error learning}.

process

Learning can be by trial and error, using instinctive movements. Accidental successes have satisfying effects. Failures have annoying effects. Behavior changes gradually, rather than by sudden insights. Over time, only correct movements survive.

Training on one task can transfer to training on different tasks, but does not necessarily transfer [Thorndike, 1903] [Thorndike, 1911].

emotion

People learn reactions, such as aggression, withdrawal, and persistence, to emotions through instrumental conditioning.

operant conditioning

If organism performs behavior and receives reward, response frequency increases {operant conditioning, learning}| {response conditioning}. Higher animals can perform new behaviors, and rewarded operants reappear more frequently. Response conditioning does not associate stimulus and response. Operant conditioning does not need goals, only rewards. Operant conditioning is stronger if rewards are unpredictable [Watson, 1913] [Watson, 1924].

puzzle-box

Instrumental learning experiments can use maze or box {puzzle-box}, from which animal escapes [Thorndike, 1903] [Thorndike, 1911].

token economy

Operant conditioning can happen in spontaneous, not learned, motor activities. Reinforced actions increase in frequency. Reward kinds and timing {token economy} affect instrumental conditioning [Bekhterev, 1913].

6-Psychology-Cognition-Learning-Kinds-Conditioning-Behavior

continuity theory of learning

People repeat behaviors useful for drive and need reduction {continuity theory of learning}. As they develop, children internalize repeated actions [Hull, 1940] [Hull, 1943].

behavior segment

As children develop, they internalize repeated actions {behavior segment}. Practice leads to memory. Young children cannot combine behavior segments, but older children can combine two behavior segments to reach goal [Hull, 1940] [Hull, 1943].

freeze

Shock, noise, or scary image {fear conditioning, freezing} can make animal stand still {freeze, animal}|.

galvanic skin conductance

Fear conditioning changes skin conductance {galvanic skin conductance}.

mediation of stimulus

External stimulus can cause covert internal response {mediation, stimulus}, which causes internal stimulus, which causes body response.

6-Psychology-Cognition-Learning-Kinds-Conditioning-Forgetting

forgetting

Over time, without stimulus repetition, conditioned responses to conditioned stimuli decrease {forgetting}|. Over time, without reinforcement, instrumental responses to conditioned stimuli decrease. All stimulus-response associative links or conditioned reflexes gradually disappear without reinforcement.

cause

Forgetting happens because events repeat without reward, not because time passed or people did not use response.

level

Forgetting can be complete, with no response or memory.

purpose

Forgetting allows retaining most-useful information.

forgetting rate

Maximum forgetting rate is immediately after learning. Forgetting rate decreases over one day and then levels off.

extinction of learning

If stimulus pairing ceases, conditioned response fades {extinction, learning}|. Extinction has same stages and processes as conditioning. Near extinction time, activity level, response variation, and response force increase [Watson, 1913] [Watson, 1924].

suppression in learning

Other learning causes forgetting {suppression, learning}|. Newer memories can modify older ones. More suppression results when more activities intervene between learning and recall. Blocking new learning prevents suppression.

6-Psychology-Cognition-Learning-Kinds-Conditioning-Laws

law of effect

Pleasurable or painful experience, above minimum level but not beyond maximum intensity, strengthens the bond between stimulus and response {law of effect}. People learn, remember, and repeat actions that immediately lead to pleasure, and these become habits. People do not remember actions leading to pain, to avoid painful behavior later [Thorndike, 1903] [Thorndike, 1911].

law of exercise

Repeating response under good conditions strengthens stimulus-response association, and reinforcement increases practice {law of exercise} {law of use} [Thorndike, 1903] [Thorndike, 1911].

law of readiness

Learning can happen if learner can respond, has interest, has background knowledge, is mature enough, and has motivation {law of readiness} [Thorndike, 1903] [Thorndike, 1911].

response-response law

Behaviors can be similar to previous behaviors {response-response law} (R-R law).

stimulus-response law

Behaviors can always happen, given environment states or events {stimulus-response law} (S-R law).

6-Psychology-Cognition-Learning-Kinds-Training

massed training

Training can take short time {massed training}.

spaced training

Training can take long time {spaced training}.
