- The phenomenon in which a taste is paired with sickness, and this causes the organism to reject—and dislike—that taste in the future.
- Temporal lobe
- The part of the cerebrum in front of (anterior to) the occipital lobe and below the lateral fissure; involved in vision, auditory processing, memory, and integrating vision and audition.
- Temporal resolution
- A term that refers to how small a unit of time can be measured; high temporal resolution means capable of resolving very small units of time; in neuroscience it describes how precisely in time a process can be measured in the brain.
- The part of the end of the axon that form synapses with postsynaptic dendrite, axon, or soma.
- Theory of mind
- The human capacity to understand minds, a capacity that is made up of a collection of concepts (e.g., agent, intentionality) and processes (e.g., goal detection, imitation, empathy, perspective taking).
- Thought-action fusion
- The tendency to overestimate the relationship between a thought and an action, such that one mistakenly believes a “bad” thought is the equivalent of a “bad” action.
- Threshold of excitation
- Specific membrane potential that the neuron must reach to initiate an action potential.
- Tip-of-the-tongue phenomenon
- The inability to pull a word from memory even though there is the sensation that that word is available.
- “Traitement moral” (moral treatment)
- A therapeutic regimen of improved nutrition, living conditions, and rewards for productive behavior that has been attributed to Philippe Pinel during the French Revolution, when he released mentally ill patients from their restraints and treated them with compassion and dignity rather than with contempt and denigration.
- Trance States
- Trance: a state of consciousness characterized by the experience of “out-of-body possession,” or an acute dissociation between one’s self and the current, physical environment surrounding them.
- Transcranial direct current stimulation (tDCS)
- A neuroscience technique that passes mild electrical current directly through a brain area by placing small electrodes on the skull.
- Transcranial magnetic stimulation (TMS)
- A neuroscience technique whereby a brief magnetic pulse is applied to the head that temporarily induces a weak electrical current that interferes with ongoing activity.
- Transfer-appropriate processing
- A principle that states that memory performance is superior when a test taps the same cognitive processes as the original encoding activity.
- Transverse plane
- See “horizontal plane.”
- Trephination
- The drilling of a hole in the skull, presumably as a way of treating psychological disorders.
- Triarchic model
- Model formulated to reconcile alternative historic conceptions of psychopathy and differing methods for assessing it. Conceives of psychopathy as encompassing three symptomatic components: boldness, involving social efficacy, emotional resiliency, and venturesomeness; meanness, entailing lack of empathy/emotional-sensitivity and exploitative behavior toward others; and disinhibition, entailing deficient behavioral restraint and lack of control over urges/emotional reactions.
- Type I error
- In statistics, the error of rejecting the null hypothesis when it is true.
- Type II error
- In statistics, the error of failing to reject the null hypothesis when it is false.
- Unconditioned response (UR)
- In classical conditioning, an innate response that is elicited by a stimulus before (or in the absence of) conditioning.
- Unconditioned stimulus (US)
- In classical conditioning, the stimulus that elicits the response before conditioning occurs.
- Value
- Belief about the way things should be.
- Vicarious reinforcement
- Learning that occurs by observing the reinforcement or punishment of another person.
- Visual hemifield
- The half of visual space (what we see) on one side of fixation (where we are looking); the left hemisphere is responsible for the right visual hemifield, and the right hemisphere is responsible for the left visual hemifield.
- Visual perspective taking
- Can refer to visual perspective taking (perceiving something from another person’s spatial vantage point) or more generally to effortful mental state inference (trying to infer the other person’s thoughts, desires, emotions).
- White matter
- The inner whitish regions of the cerebrum comprised of the myelinated axons of neurons in the cerebral cortex.
- Working memory
- The form of memory we use to hold onto information temporarily, usually for the purposes of manipulation.
