Glossary Flashcards
Propagated electrical potential responsible for transmitting neural infor mation and for communication between neurons. Action potentials typically travel down a neuron’s axon. (2)
Action potential
A subcortical structure that is involved in processing emotional aspects of expe- rience, including memory for emotional events. (8)
Amygdala
A technique in which people compare two problems that illustrate a principle. This technique is designed to help people discover similar structural features of cases or problems. (12)
Analogical encoding
People find it difficult to apply analogies in laboratory settings, but routinely use them in real-world settings. (12)
Analogical paradox
The use of analogies as an aid to solving problems. Typically, a solution to one problem, the source problem, is presented that is analogous to the solution to another problem, the target problem. (12)
Analogical problem solving
Transferring experience in solving one problem to the solution of another, similar problem. (12)
Analogical transfer
Making a comparison in order to show a similarity between two different things. (12)
Analogy
A procedure used by early psychologists in which trained participants described their experiences and thought processes in response to stimuli. (1)
Analytic introspection
An inference that connects an object or person in one sentence to an object or person in another sentence. See also Causal inference; Instrument inference. (11)
Anaphoric inference
Area in the temporal lobe. Damage to the ATL has been connected with semantic deficits in dementia patients and with the savant syndrome. (9)
Anterior temple lobe (ATL)
An illusion of movement perception that occurs when stimuli in different locations are flashed one after another with the proper timing. (3)
Apparent movement
Rehearsal process involved in working memory that keeps items in the phonological store from decaying. (5)
Articulatory rehearsal process
Interference with operation of the phonological loop that occurs when a person repeats an irrelevant word such as “the” while carrying out a task that requires the phonological loop. (5)
Articulatory suppression
The ability of a computer to perform tasks usually associated with human intelligence. (1)
Artificial intelligence
Focusing on specific features, objects, or locations or on certain thoughts or activities. (4)
Attention
A rapid shifting of attention, usually caused by a stimulus such as a loud noise, bright light, or sudden movement. (4)
Attentional capture
Anne Treisman’s model of selective attention that proposes that selection occurs in two stages. In the first stage, an attenuator analyzes the incoming message and lets through the attended message and also the unattended message, but at lower (attenuated) strength. (4)
Attenuation model of attention
In Treisman’s model of selective attention, the attenuator analyzes the incoming message in terms of physical characteristics, language, and meaning. Attended messages pass through the attenuator at full strength, and unattended messages pass though with reduced strength. (4)
Attenuator
Memory for specific events from a person’s life, which can include both episodic and semantic components. (6)
Autobiographical Memory
Processing that occurs automatically, without the person’s intending to do it, and that also uses few cognitive resources. Automatic processing is associated with easy or well-practiced tasks. (4)
Automatic processing
Events that are more easily remembered are judged to be more probable than events that are less easily remembered. (13)
Availability heuristic
Part of the neuron that transmits signals from the cell body to the synapse at the end of the axon. (2)
Axon
A process by which learning can occur in a connectionist network, in which an error signal is transmitted backward through the network. This backward transmitted error signal provides the information needed to adjust the weights in the network to achieve the correct output signal for a stimulus. (9)
Back propagation
When a word has more than one meaning and all meanings a equally likely. (11)
Balanced dominance
The idea that our estimate of the probability of an outcome is determined by the prior probability (our initial belief) and the likelihood (the extent to which the available evidence is consistent with the outcome). (3)
Bayesian inference
A condition caused by brain damage in which a person has difficulty focusing attention on individual objects. (4)
Balint’s syndrome
The relative proportions of different classes in a population. Failure to consider base rates can often lead to errors of reasoning. (13)
Base rate
In Rosch’s categorization scheme, the level below the global (superordinate) level (e.g., “table” or “chair” for the superordinate category “furniture”). According to Rosch, the basic level is psychologically special because it is the level above which much information is lost and below which little is gained. See also Global level; Specific level. (9)
Basic level
The approach to psychology, founded by John B. Watson, which states that observable behavior provides the only valid data for psychology. A consequence of this idea is that consciousness and unobservable mental processes are not considered worthy of study by psychologists. (1)
Behaviourism
Tendency to think a syllogism is valid if its conclusion is believable or that it is invalid if the conclusion is not believable. (13)
Belief bias
When a word has more than one meaning and one meaning is more likely. (11)
Biased dominance
Process by which features such as color, form, motion, and location are combined to create perception of a coherent object. (4)
Binding
The problem of explaining how an objects individual features become bound together. Bottleneck model Model of attention that proposes that incoming information is restricted at some point in so only a portion information gets through to conscious ness. processing, example model. (4)
Binding problem
Model of attention that proposes that incoming information is restricted at some point in processing, so only a portion of the information gets through to consciousness. Broadbent’s model of attention is an example of a bottleneck model. (4)
Broadbent’s model
Processing that starts with information received by the receptors. This type of processing is also called data-based processing (3)
Bottom-up processing
A procedure in which a specific area is removed from an animal’s brain. It is usually done to determine the function of this area by assessing the effect on the animal’s havior. (3)
Brain ablation
Technique such as functional magnetic resonance imaging (fMRI results in images of the brain that represent brain activity. In cognitive psychology, activity is measured in response to specific cognitive tasks. (2)
Brain imaging
A condition associated with damage to Broca’s area, in the frontal lobe, characterised by labored ungrammatical speech and difficulty in understanding some types of sentences. (11)
Broca’s aphasia
An area in the frontal lobe associated with the production of language. Damage to this area causes Broca’s aphasia. (2)
Broca’s area
A problem, first described by Duncker, in which a person is given a number of objects and is given the task of mounting a candle on a wall so it can burn without dripping wax on the floor. This problem was used to study functional fixedness. (12)
Candle problem
