capacity models / resource allocation models (of divided attention): those models proposing that we have a pool of processing resources that we can allocate according to the demands of the task and environmental factors.

cardiovascular system: consists of two parts, the heart and the blood vessels. It is a system for distributing oxygen and nutrients to the organs in the body. Heart rate, blood pressure and local blood volume are three measures of cardiovascular activity commonly used in research by psychophysiologists.

case study: a detailed description of a single individual, typically used to provide information on the person's history and to aid in interpreting the person's behaviour.

castration anxiety: the anxiety that boys suffer during the Oedipus complex that their rivalrous father may castrate them.

CAT (computed axial tomography) scans: a non-invasive, multiple X-ray procedure for creating images of the brain.

cataplexy: sudden paralysis of some or all muscles brought on by laughter, anger, or strong emotions; a hallmark of narcolepsy.

catatonic schizophrenia: a form of schizophrenia, characterised by a patient who displays motor abnormalities, for instance, changing between a state of complete immobility to energised excitement.

categorisation: a short cut used when processing information. A category is a set of items perceived to have at least one feature in common. In interpersonal perception, categories such as young-old and male-female are used.

catharsis: a term used in psychodynamic psychology to mean the release of emotion. An example is crying to release sadness.

cause and effect: establishing that the independent variable has had a clear effect upon the dependent variable.

central core: this exists in all vertebrates.  The central core regulates the basic life processes such as breathing, pulse, arousal, movement, balance, sleep and also the early stages of processing sensory information.  The central core includes the thalamus, pons, cerebellum, reticular formation and medulla.

cerebellum: ('little brain' in Latin) two small hemispheres located beneath the cortical hemispheres, at the back of the head; the cerebellum plays an important role in directing movements and balance.

cerebral cortex: an area of the brain resembling a folded sheet of grey tissue that covers the rest of the brain. The cerebral cortex directs the brains higher cognitive and emotional functions.  It is divided into two almost symmetrical halves called the cerebral hemispheres.  Each hemisphere contains four lobes.  Areas within these lobes regulate all forms of conscious experience such as emotion, perception, thought and planning as well as unconscious cognitive and emotional processes.  The cerebral cortex includes the frontal lobe, occipital lobe, parietal lobe and temporal lobe.

cerebral dominance: the tendency for one hemisphere to be superior for particular functions.

cerebral hemispheres: two half spheres, made up of the cortex and underlying structures, which comprise the major portion of the brain.

chaos theory: a branch of mathematics dealing with non-linear functions which has been applied to the modelling of situations such as the weather and stock markets; non-linear systems are not predictable, because very small changes in initial conditions can result in radical differences at a later point.

charisma: a personal attractiveness or interestingness that enables you to influence others.

checklist: a simple list of all the behaviours being recorded. On every occurrence of a behaviour on the list, a single tally is recorded. At the end of the observation period, the observer has a record of the number of occurrences of each of the behaviours being investigated.

child psychology: ( developmental psychology) the branch of psychology that studies the social and mental development of children.

child rearing styles: varying style of parenting classified according to the extent parents are demanding of their child and/or responsive to the childs needs, including authoritative and authoritarian parenting.

chi-squared (x2) test of association: a nonparametric inferential statistical test. Used when you have nominal data, the research is independent groups and you are looking for an association between the independent variable and the dependent variable.

circadian rhythm: a roughly 24-hour cycle which is determined by an internal body clock, e.g. the sleep-wake cycle.

classical conditioning: a basic form of learning, whereby a neutral stimulus is repeatedly paired with an unconditioned stimulus (UCS), that naturally produces an unconditioned response (UCR). After several trials, the neutral stimulus is now a conditioned stimulus (CS) and thus produces a conditioned response (CR).

claustrophobia: an intense fear of confined spaces such as lifts.

client-centred therapy: an humanistic approach to therapy developed by Carl Rogers, in which the person seeking treatment (termed a client), not the therapist, is seen as directing the process of therapy; later called person-centred therapy.

cognitive appraisal theory: devised by Lazarus, stating that our cognitive appraisal of a situation in crucial in experiencing emotions.

cognitive behavioural programmes: programmes designed to modify behaviour by changing attitudes and thoughts.

cognitive behavioural therapies: techniques that involve helping clients to identify their negative, irrational thoughts and to replace these with more positive, rational ways of thinking.

cognitive development: the growth of cognitive (thinking) abilities. This may be studied by examining changes in the form and structure of children's thinking as they get older, or by looking at individual differences in the power of children's thinking as measured, e.g. by IQ tests.

cognitive dissonance: in Festinger's theory, a state of tension created when there are conflicts between an individual's behaviour and beliefs, or between two beliefs.

cognitive interview: an interview technique designed to be used by police investigators to help elicit accurate information from eyewitnesses.

cognitive labelling theory: Schachter and Singer's theory that it is the combination of physiological arousal and cognitive appraisal that leads to the experience of emotion.

cognitive map: Tolman's term for the mental representation of learned relationships among stimuli.

cognitive science: the study of human intelligence and of the symbol-processing nature of cognition.

cognitive therapy: a form of therapy which focuses on the role of faulty beliefs and thought patterns in abnormal behaviour; because it also encourages testing beliefs via behavioural strategies, it is sometimes called' cognitive behavioural therapy'. See also rational-emotive therapy.

Children begin thinking logically about concrete events, but have difficulty understanding abstract or hypothetical concepts.

concurrent validity: an indicator of validity, which compares measures of the same phenomenon to determine whether they produce similar results in the same circumstances.

conditional positive regard: acceptance and caring given to a person only for meeting certain standards of behaviour.

conditioned emotional response: an emotional response such as fear which is established through classical conditioning.

conditioned reinforcer: stimuli which act as reinforcers but are not based on biological survival, such as attention, praise or money.

confirmation: in research, the process of determining that observations are consistent with the hypothesis being true.

confirmation bias: a form of cognitive error based on the tendency to seek out information which supports one's beliefs, and ignore contradictory information.

conformity: a type of social influence expressed through exposure to the views of a majority and our submission to those views.

confound: in experimental research, a situation where two variables change simultaneously, making it impossible to determine their relative influence.

confounding variable: uncontrolled variable that produces an unwanted effect on the dependent variable. It obscures the effect of the independent variable.

congruence: in Rogers's theory, a feeling of integration experienced when the self and ideal self match.

conscience: a person's moral sense of right and wrong, chiefly as it affects their own behaviour.

conscious: in Freud's theory, that aspect of the mind which contains those thoughts and feelings of which we are immediately aware at a given moment.

consciousness: is regarded to comprise qualities such as subjectivity, self-awareness, sentience, and the ability to perceive the relationship between oneself and one's environment. It is a subject of much research in philosophy of mind, psychology, neuroscience, and cognitive science.

consent: an ethical necessity, whereby participants agree to procedures that will take place and are given the right to withdraw at any time in the study.

conservation: understanding that physical characteristics of number or quantity do not change, even though the appearance may change, and is demonstrated by children in the pre-operational stage of Piagets theory of development.

consequent control: a behavioural measure in which the intervention follows the behaviour to be changed. Consequent procedures can affect behaviours by using pleasant or unpleasant consequences (positive or negative reinforcement or punishment) to make their performance more or less likely or through the use of feedback.

constant errors: uncontrolled variables that act on only one level of the independent variable. Their action may either be in the same direction as a predicted difference, exaggerating the apparent effect of the independent variable or in the opposite direction, obscuring the effect of the independent variable.

constructive theories of perception: top-down (or concept driven) theories that emphasise the need for several sources of information in order to construct our perception of the world. In addition to information available in the sensory stimulus, we need to use higher cognitive processes, according to this theory, to interpret the information appropriately.

construct validity: an indicator of validity, which aims to demonstrate that the phenomenon being measured actually exists, for example, by justifying it in relation to a model or theory.

contact hypothesis: suggestion that prejudice can be reduced if members of different groups are brought into contact with each other.

content analysis: examination of certain types of media (e.g. books, TV; magazines, the Internet) to see what effect they may be having on our perceptions and/or behaviour. It involves the analysis of language, certain words or certain activities that appear in the chosen media.,

context-dependent forgetting: failure to retrieve information from long-term memory due to the absence of appropriate contextual cues.

contiguity: in behaviourism, the principle that a reinforcer must occur immediately after a response in order for learning to occur.

contextual reinstatement: in the context of criminal psychology, a way of improving memory for an event by returning to the place where it happened or asking the witness to imagine themselves back in that place and in the same emotional state.

contingency of reinforcement: in operant conditioning, a description of the relationship between a response and a reinforcer.

continuity: in developmental theory, the view that changes occur through a continuous gradual process, rather than as a series of discrete stages; continuity is an assertion about the processes that underlie development, as well as the changes observed in behaviour.

continuous reinforcement: a reinforcement schedule in which every response is followed by a reinforcer; equivalent to an FR (Fixed Ratio) 1 schedule.

contrast processing: term used in the study of visual perception to describe the ability to differentiate between brightness levels in adjoining areas.

control(psychological): the sense that one can anticipate events that occur in one's environment - a feeling that one can accomplish things and is not at the mercy of forces beyond one's control. Types of control include: informational, decisional, behavioural, cognitive and retrospective.

controlled (attentional) processing: a mental operation that is conscious, relatively slow and easily interrupted.

controls: the steps taken to limit factors that could distort the collection of valid and reliable data.

convenience sample: a quasi-random sampling procedure in which the potential sample pool actually differs from the population - for example, selecting university students instead of people in general; the impact on representativeness (if any) often depends on what behaviour is being studied.

convergent problem: a problem which has a single solution, and all elements lead towards that solution; also called closed-end or well-defined problems.

coping: a person's efforts to minimise, control or tolerate environmental demands that are judged to exceed their resources to fight or avoid.

coprolalia: an uncontrollable use of obscene language; often accompanied by mental disorders.

corpus callosum: a wide band of nerve fibres which connect the two hemispheres of the brain.

correlation: the degree of relatedness between two sets of scores. If two sets of scores are correlated, it enables researchers to predict (with varying degrees of certainty) the approximate value of one score if they know the value of the other. A positive correlation exists when high values on one variable are associated with high values on another variable. A negative correlation exists when high values on one variable are associated with low values on another variable.

correlational analysis: a type of analysis used to measure the extent of relationship between variables that are thought likely to co-vary.

correlation coefficient: a descriptive statistic measuring the degree of relationship between two variables; for positive correlations, it is a number which varies between 0.0 and + 1.0, and for negative correlations between 0.0 and -1.0; in both cases, the closer the value is to I, the stronger the relationship between the two variables.

cortex the outer layer of the brain which controls many of our higher functions like speech and perception.

cortical activity: neural activity in the cortex of the brain.

corticosteroids: drugs that mimic the action of a group of hormones produced by adrenal glands; they are anti-inflammatory and act as bronchodilators.

counter balancing: the systematic variation of the order of presentation of the levels of the independent variable (eg. Half of the participants first undergo Condition A followed by Condition B, whilst the other half do vice versa), in a repeated measures design, to avoid order and fatigue effects.

counter factual thinking: thinking about events that did not actually take place, such as winning when we in fact lost.

counter transference: as part of psychoanalytic therapy, the therapist may transfer feelings or conflicts they may have about their own life, or significant others in it, onto the client. It is imperative that the therapist recognises this possibility and guards against it.

co-variation model of attribution: Kelley's theory that people decide on the cause of a behaviour by weighing up how consistent and distinctive the behaviour is and how much consensus there is about it.

covariation principle: proposes that individuals attribute behaviour to a causal factor if it existed whilst the behaviour took place, but was not there when it did not occur.

Craik and Lockhart (1972): put forward the levels of processing model of memory, as a counterpoint to the multi-store model of memory. Memory is seen as a product of the depth of processing and encoding of information; for instance shallow processing or deep processing (e.g. semantic processing).

creativity: the capacity to produce something which is both unique and useful.

criminal psychology: is the study of the wills, thoughts, intentions and reactions of criminals.

crisis: a psychological conflict which needs to be resolved if the individual is to move on to the next stage of development.

criterion: a standard or test by which individual things or people may be compared and judged.

critical period: a crucial period in a person's or animal's development when certain experiences must happen for normal development to proceed. Today it is more common to use the term sensitive period to describe the optimum period for certain experiences to happen.

critical value: the value that is compared with the observed (calculated) value in an inferential statistical test. Each inferential statistical test has a table or tables of critical values. The comparison with the observed (calculated) allows you to conclude if you have found a significant result.

cross cultural study: a study conducted across two or more cultures in order to make comparisons between them.

cross sectional sample: a sample which is deliberately selected in such a way that the sample matches the population for particular characteristics, such as age and income.                                                                                                                     

cross sectional study: a research design based on selecting representative groups who vary on a particular characteristic; when the characteristic is age, this design provides a means of making developmental comparisons.

cross tolerance:this phenomenon arises in some drug categories, such as the opiates (heroin, morphine etc) and tryptamines (LSD, mescaline and psilocybin) when the prolonged use of one drug in the group results in the development of tolerance to the others opioids.

crowd: may refer to a large, cohesive gathering of individuals or to the act of coming together to form a tightly-spaced group. In addition, crowding is used to refer to the psychological perceptions associated with this increase in density.

crowding: the feeling that is induced if our expectations about the use of space are violated by the presence of others.

crystallised intelligence: knowledge and skills already acquired by a person, e.g. arithmetic.

cue-arousal theory: suggests that the presence of specific cues in the environment triggers aggressive behaviour.

cue-dependent coding: the concept that all information is stored in memory as a set of relationships called the context; remembering is seen as dependent on restoring the cues which formed the original context.

cue-dependent forgetting: failure to recall memory due to a lack of cues that were present at the time of memory encoding.

cultural bias: a tendency in psychological theory and research to ignore the differences between cultures and impose understanding based on the study of one culture alone.

cultural identity: the influence of one's culture on the development of identity. Individualist cultures stress the importance of personal achievement and independence, while collectivist cultures stress the importance of collective achievement and dependence.

cultural relativism: in the context of atypical psychology, the acknowledgement that symptoms may differ across cultures.

culture: a system of values, beliefs and practices that characterise a particular group, for example a national or ethnic group.

culture-bound syndrome: A mental disorder that appears to be confined to the members of a particular cultural group.
