Conditioning

Question 231

The state in which an individual considers love and respect to be conditional on meeting the approval of others - This belief derives from the child's sense of being worthy of love on the basis of parental approval: as the individual matures, he or she, may continue to feel worthy of affection and respect only when expressing desirable behaviors

Answer 231

Conditions of Worth

Question 232

A persistent pattern of behavior that involves violating the basic rights of others and ignoring age appropriate social standards - Specific behaviors include lying, theft, arson, running away from home, aggression, truancy, burglary, cruelty to animals, and fighting - This disorder is distinguished from oppositional defiant disorder by the increased severity of the behaviors and their occurrence independently of an event occasioning opposition

Confabulation

Question 235

A range of values used for estimating the value of a population parameter from data obtained in a sample, with a preset, fixed probability that the interval will include the true value of the population parameter being estimated - Most research is done on samples, but it is done in order to draw inferences about the entire relevant population

Answer 235

Confidence Interval

Question 236

The probability that a confidence interval contains the true value of an experimental variable under investigation - It is expressed as a percentage that indicates the statistical likelihood that the value of the variable obtained using a sample is an accurate reflection of the actual value in the entire population - For example, a survey of 100 individuals in a small town of 1,000 people might indicate that 20% of respondents intend to enroll in a distance learning class within the next month - If this type of level for this research is 95%, this indicates that if the entire town were surveyed then the results obtained would be within 5% of the value obtained with the sample (ie, anywhere between 16 and 24% of respondents would enroll in a class) - In other words, the researcher is 95% certain that his or her results for the sample are accurate for the entire population and thus would be obtained were the research to be repeated with additional samples

One of a set of procedures used in factor analysis to demonstrate that a group of variables possess a theoretically expected factor structure - In other words, this provides formal statistical tests of a priori hypotheses about the specific underlying (latent) variables thought to explain the data obtained on a set of observed (manifest) variables - Unlike explatory factor analysis, in which all measured variables relate to all latent factors, this imposes explicit restrictions so that the measured variables relate with some or one latent factors but do not relate with others

Answer 241

Confirmatory Factor Analysis

Question 242

The occurrence of mutually antagonistic or opposing forces, including events, behaviors, desires, attitudes, and emotions - This general term has more specific meanings within different areas of psychology - For example, in psychoanalytic theory it refers to the opposition between incompatible instinctual impulses or between incompatible aspects of the mental structure (ie; the id, ego, and superego) that may be a source of neurosis if it results in the use of defense mechanisms other than sublimation - In interpersonal relations this denotes the disagreement, discord, and friction that occur when the actions or beliefs of one or more individuals are unacceptable to and resisted by others

Answer 251

Connectionism

Question 252

Any of a class of theories hypothesizing that knowledge is encoded by the connections among representations stored in the brain rather than in the representations themselves - These models suggest that knowledge is distributed rather than being localized and that it is retrieved through spreading activation among connections - This model concept has been extended to artificial intelligence, particularly to its neural network models of problem solving

Answer 252

Connectionist Model

Question 253

An individual’s sense of right and wrong or of transgression against moral values - In psychoanalysis, this is the superego, or ethical component of personality, which acts as judge and critic of one's actions and attitudes - More recent biopsychological approaches suggest that the capacity of this may be genetically determined, and research on brain damage connects behavioral inhibitions to specific brain regions (eg; the prefrontal cortex) - Psychological approaches emphasize the role of this in the formation of groups and societies

Answer 253

Conscience

Question 254

1. In classical psychoanalytic theory of Austrian psychiatrist Sigmund Freud (1856 - 1939) the region of the psyche that contains thoughts, feelings, perceptions, and other aspects of mental life currently present in awareness - The content of it is thus inherently transitory of continuously changing 2.

Conservation

Question 260

A relatively new subfield of psychology that seeks to understand the attitudes and behavior of individuals and groups toward the natural environment so as to promote their use of environmentally sustainable practices - Because of the highly diverse categories of behavior being studied, they generally focus on specific actions, such as paper recycling, rather than general tendencies - It is distinct in its orientation toward protecting ecosystems and preserving resources while ensuring quality of life for humans and other species

Question 275

The theory that people belonging to one group can become less prejudiced against (and perhaps more favorably disposed toward) members of other groups merely through increased contact with them - It is now thought that greater contact is unlikely to reduce inter group prejudice unless the people from the different groups are of equal status, are not in competition with each other, and do not readily categorize the others as very different from themselves

Answer 275

Contact Hypothesis

Question 276

In social theory, the spread of behaviors, attitudes, and affect through crowds and other types of social aggregation from one member to another - Early analyses of this suggested that it resulted from the heightened suggestibility of members, but subsequent studies have argued that this is sustained by relatively mundane interpersonal processes, such as comparison, imitation, social facilitation, conformity, and universality

An intelligence test based on common human experience designed to apply across social lines and to permit fair comparisons among people from different cultures - Nonverbal, nonacademic items are used, such as matching identical forms, selecting a design that completes a given series, or drawing human figures - Studies have shown, however, that any test reflects certain cultural norms in some degree, and hence may tend to favor members of certain cultures over members of others

Answer 382

Culture Fair Test

Question 383

An intelligence test designed to eliminate cultural bias completely by constructing questions that contain either no environmental influences or no environmental influences that reflect any specific culture - However, the creation of such a test is probably impossible, and psychometricians instead generally seek to develop culture fair tests
