How does the brain think? Flashcards
dichotic listening
Experimental procedure for simultaneously presenting a different auditory input to each ear through stereophonic earphones.
social neuroscience
Interdisciplinary field that seeks to understand how the brain mediates social interactions.
brain connectome
Map of the complete structural and functional neural connections of the human brain in vivo.
consciousness
The mind’s level of responsiveness to impressions made by the senses.
convergent thinking
Form of thinking that searches for a single answer to a question (such as 2 + 2 = ?); contrasts with divergent thinking.
neuroeconomics
Interdisciplinary field that seeks to understand how the brain makes decisions.
theory of mind
ability to attribute mental states to others
cell assembly
Hypothetical group of neurons that become functionally connected because they receive the same sensory inputs. Hebb proposed that cell assemblies were the basis of perception, memory, and thought.
attention
Selective narrowing or focusing of awareness to part of the sensory environment or to a class of stimuli.
divergent thinking
Form of thinking that searches for multiple solutions to a problem (such as How many different ways can a pen be used?); contrasts with convergent thinking.
intelligence B
Hebb’s term for observed intelligence, which is influenced by experience as well as other factors in the course of development and is measured by intelligence tests.
perseveration
Tendency to emit repeatedly the same verbal or motor response to varied stimuli.
binding problem
Philosophical question focused on how the brain ties single and varied sensory and motor events together into a unified perception or behavior.
syntax
ways in which words are put together to form phrases, clauses, or sentences; proposed to be a unique characteristic of human language
intelligence A
Hebb’s term for innate intellectual potential, which is highly heritable and cannot be measured directly.
cognition
Act or process of knowing or coming to know; in psychology, used to refer to the processes of thought.
cognitive neuroscience
Study of the neural bases of cognition.
hyperconnectivity
Increased local connections between two related brain regions.
split brain
Surgical disconnection of the two hemispheres in which the corpus callosum
anomalous speech representation
Condition in which a person’s speech zones are located in the right hemisphere or in both hemispheres.
synesthesia
ability to perceive a stimulus of one sense as the sensation of a different sense, as when sound produces a sensation of color; literally, ‘felt together.’
psychological construct
Idea, resulting from a set of impressions, that some mental ability exists as an entity; examples include memory, language, and emotion.
contralateral neglect
Ignoring a part of the body or world on the side opposite (contralateral to) that of a brain injury.
mirror neuron
Cell in the primate premotor cortex that fires when an individual observes a specific action taken by another individual.
extinction
In neurology, neglect of information on one side of the body when it is presented simultaneously with similar information on the other side of the body.
association cortex
Neocortex outside the primary sensory and motor cortices that functions to produce cognition.
