Identical twins: Two individual organisms that originated from the same zygote and therefore are genetically identical or very similar. The epigenetic profiling of identical twins discordant for disease is a unique experimental design as it eliminates the DNA sequence-, age-, and sex-differences from consideration.
Identity: Sometimes used synonymously with the term “self,” identity means many different things in psychological science and in other fields (e.g., sociology). In this module, I adopt Erik Erikson’s conception of identity as a developmental task for late adolescence and young adulthood. Forming an identity in adolescence and young adulthood involves exploring alternative roles, values, goals, and relationships and eventually committing to a realistic agenda for life that productively situates a person in the adult world of work and love. In addition, identity formation entails commitments to new social roles and reevaluation of old traits, and importantly, it brings with it a sense of temporal continuity in life, achieved though the construction of an integrative life story.

Incidental learning: Any type of learning that happens without the intention to learn.
Independent: Two characteristics or traits are separate from one another-- a person can be high on one and low on the other, or vice-versa.

Independent self: The tendency to define the self in terms of stable traits that guide behavior.
Independent self: A model or view of the self as distinct from others and as stable across different situations.

Interdependent self: A model or view of the self as connected to others and as changing in response to different situations. The goal of the interdependent self is to suppress personal preferences and desires, and to adjust to others.

Law of effect: The idea that instrumental or operant responses are influenced by their effects. Responses that are followed by a pleasant state of affairs will be strengthened and those that are followed by discomfort will be weakened. Nowadays, the term refers to the idea that operant or instrumental behaviors are lawfully controlled by their consequences.
Lesion: A region in the brain that suffered damage through injury, disease, or medical intervention.
Letter of recommendation effect: The general tendency for informants in personality studies to rate others in an unrealistically positive manner. This tendency is due a pervasive bias in personality assessment: In the large majority of published studies, informants are individuals who like the person they are rating (e.g., they often are friends or family members) and, therefore, are motivated to depict them in a socially desirable way. The term reflects a similar tendency for academic letters of recommendation to be overly positive and to present the referent in an unrealistically desirable manner.

For example, suppose that a mother has three children; two of these children are very sociable and outgoing, whereas the third is relatively average in sociability. Because of operation of this effect, the mother will rate this third child as less sociable and outgoing than he/she actually is. More generally, this effect causes parents to exaggerate the true extent of differences between their children.

Tertiary education: Education or training beyond secondary school, usually taking place in a college, university, or vocational training program.
The Age 5-to-7 Shift: Cognitive and social changes that occur in the early elementary school years that result in the child’s developing a more purposeful, planful, and goal-directed approach to life, setting the stage for the emergence of the self as a motivated agent.
The “I”: The self as knower, the sense of the self as a subject who encounters (knows, works on) itself (the Me).
The “Me”: The self as known, the sense of the self as the object or target of the I’s knowledge and work.
The norm of reciprocity: The normative pressure to repay, in equitable value, what another person has given to us.
The rule of scarcity: People tend to perceive things as more attractive when their availability is limited, or when they stand to lose the opportunity to acquire them on favorable terms.
The triad of trust: We are most vulnerable to persuasion when the source is perceived as an authority, as honest and likable.
Theories: Groups of closely related phenomena or observations.
Theory of mind: Emerging around the age of 4, the child’s understanding that other people have minds in which are located desires and beliefs, and that desires and beliefs, thereby, motivate behavior.
Theory of mind: Children’s growing understanding of the mental states that affect people’s behavior.
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.
Top-down processing: Experience influencing the perception of stimuli.
“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.
Transduction: The conversion of one form of energy into another.
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.
Transgender: A term used to describe individuals whose gender does not match their biological sex.
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.
Trichromatic theory: Theory proposing color vision as influenced by three different cones responding preferentially to red, green and blue.
Trigger features: Specific, sometimes minute, aspects of a situation that activate fixed action patterns.
Tympanic membrane: Thin, stretched membrane in the middle ear that vibrates in response to sound. Also called the eardrum.
Type A Behavior: Type A behavior is characterized by impatience, competitiveness, neuroticism, hostility, and anger.
Type B Behavior: Type B behavior reflects the absence of Type A characteristics and is represented by less competitive, aggressive, and hostile behavior patterns.
Unconditional positive regard: In person-centered therapy, an attitude of warmth, empathy and acceptance adopted by the therapist in order to foster feelings of inherent worth in the patient.
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.
Universalism: Universalism proposes that there are single objective standards, independent of culture, in basic domains such as learning, reasoning, and emotion that are a part of all human experience.
Unusual uses: A test of divergent thinking that asks participants to find many uses for commonplace objects, such as a brick or paperclip.
Validity: Evidence related to the interpretation and use of test scores. A particularly important type of evidence is criterion validity, which involves the ability of a test to predict theoretically relevant outcomes. For example, a presumed measure of conscientiousness should be related to academic achievement (such as overall grade point average).
Value judgment: An assessment—based on one’s own preferences and priorities—about the basic “goodness” or “badness” of a concept or practice.
Value-free research: Research that is not influenced by the researchers’ own values, morality, or opinions.
Ventral pathway: Pathway of visual processing. The “what” pathway.
Verbal persuasion: When trusted people (friends, family, experts) influence your self-efficacy for better or worse by either encouraging or discouraging you about your ability to succeed.
Vestibular system: Parts of the inner ear involved in balance.
Vicarious performances: When seeing other people succeed or fail leads to changes in self-efficacy.
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).
Weber’s law: States that just noticeable difference is proportional to the magnitude of the initial stimulus.
White matter: The inner whitish regions of the cerebrum comprised of the myelinated axons of neurons in the cerebral cortex.
Working memory: Memory system that allows for information to be simultaneously stored and utilized or manipulated.
Working memory: The form of memory we use to hold onto information temporarily, usually for the purposes of manipulation.
Working memory: The ability to maintain information over a short period of time, such as 30 seconds or less.
