The brain and the spinal cord.

Central Tendency

A statistical measurement attempting to depict the average score in a distribution (see mean, median, and/or mode)

Centration

Cerebral Hemispheres

The two halves of the brain (right and left)

Chemical Imbalance

A generic term for the idea that chemical in the brain are either too scarce or too abundant resulting in or contributing to a mental disorder such as schizophrenia or bipolar disorder. Others believe that the disorder precedes the imbalance, suggesting that a change in mood, for example, changes our chemicals rather than the chemical changing our mood.

Chunk

A unit of information used in memory

Chunking

Combining smaller units of measurement or chunks into larger chunks. (e.g., a seven chunk phone number such as 5-5-5-1-2-1-2 becomes a five chunk number such as 5-5-5-12-12)

Classical Conditioning

The behavioral technique of pairing a naturally occurring stimulus and response chain with a different stimulus in order to produce a response which is not naturally occurring.

Client Centered Therapy A humanistic therapy based on Carl Roger's beliefs that an individual has an unlimited capacity for psychological growth and will continue to grow unless barriers are placed in the way.

Coefficient of Determination

The statistic or number determined by squaring the correlation coefficient. Represents the amount of variance accounted for by that correlation.

Coercive Power

Power derived through the ability to punish.

Cognition

The process of receiving, processing, storing, and using information.

Cognitive Behavioral Therapy

Treatment involving the combination of behaviorism (based on the theories of learning) and cognitive therapy (based on the theory that our cognitions or thoughts control a large portion of our behaviors).

Cognitive Dissonance

he realization of contradictions in one's own attitudes and behaviors.

Cognitive Psychology

The sub-field of psychology associated with information processing and the role it plays in emotion, behavior, and physiology.

Cognitive Therapy

The treatment approach based on the theory that our cognitions or thoughts control a large part of our behaviors and emotions. Therefore, changing the way we think can result in positive changes in the way we act and feel.

Cohort Effects

The effects of being born and raised in a particular time or situation where all other members of your group has similar experiences that make your group unique from other groups

Collective Unconscious

According to Jung, the content of the unconscious mind that is passed down from generation to generation in all humans.

Compulsion

Concrete Operational Stage

According to Piaget, the stage of cognitive development where a child between the ages of 7 and 12 begins thinking more globally and outside of the self but is still deficient in abstract thought.

Concurrent Validity

A measurements ability to correlate or vary directly with an accepted measure of the same construct

Conditioned Response

The response in a stimulus-response chain that is not naturally occurring, but rather has been learned through its pairing with a naturally occurring chain.

Conditioned Stimulus

The stimulus in a stimulus-response chain that is not naturally occurring, but rather has been learned through its pairing with a naturally occurring chain.

Conditioning

The process of learning new behaviors or responses as a result of their consequences.

Confidence Interval

The level of certainty that the true score falls within a specific range. The smaller the range the less the certainty.

Conformity

Changing your attitudes, beliefs, thoughts, or behaviors in order to be more consistent with others.

Confound

Any variable that is not part of a research study but still has an effect on the research results

Conscience

According to Freud, the restriction demanded by the superego.

Consciousness

Awareness of yourself and the world around you.

Conservation

he understanding, typically achieved in later childhood, that matter remains the same even when the shape changes (i.e., a pound of clay is still a pound of clay whether is is rolled in a ball or pounded flat).

Consolidation

The physiological changes in the brain associated with memory storage.

Consolidation Failure

The failure to store information in memory.

Constant

Any variable that remains the same throughout a study.

Construct

any variable that can not be directly observed but rather is measured through indirect methods. (Examples: intelligence, motivation)

Construct Validity

The general validity of a measuring device. Construct validity answers the question of whether or not the measuring device actually measures the construct under question.

Content Validity

A measurement device’s ability to be generalized to the entire content of what is being measured.

Context Dependent Memory

The theory that information learned in a particular situation or place is better remembered when in that same situation or place.

Continuous Reinforcement

The application of reinforcement every time a specific behavior occurs.

Control Group

The group of subjects in an experiment that does not receive the independent variable.

Convergence

The binocular cue to distance referring to the fact that the closer an object, the more inward our eyes need to turn in order to focus

Convergent Thinking

Logical and conventional thought leading to a single answer.

Conversion Disorder

A somatoform disorder where the individual experiences a loss of sensation or function due to a psychological belief (e.g., paralysis, blindness, deafness).

Correlated Sample

Sample data that is related to each other.

Correlation

The degree to which two or more variables a related to each other. A correlation refers to the direction that the variables move and does not necessarily represent cause and effect. (Example: height and weight are correlated. As one increases, the other tends to increase as well)

Correlation Coefficient

The statistic or number representing the degree to which two or more variables are related. Often abbreviated 'r.'

Counterconditioning

The use of conditioning to eliminate a previously conditioned response. The conditioned stimulus (CS) is repaired with a different unconditioned stimulus (UCS) to eventually elicit a new conditioned response (CR)
