Abnormal Psych Test

Test 1 Chapter 3
Show Answers:

  1. Diagnosis
    Process of determining whether a presenting problem meets the established criteria for a specific psychological disorder.
  2. Dimensional Approach
    Method of categorizing characteristics on a continuum rather than on a binary, either-or, or all-or-none basis.
  3. Double-blind control
    Procedure in outcome studies that prevents bias by ensuring that neither the subjects nor the providers of the experimental treatment know who is receiveing treatment and who is receiving placebo.
  4. Epidemiology
    Psychopathology reaserch method examining the prevalence, distribution, and consequences of disorders in populations.
  5. Generalizability
    Extent to which research results apply to a range of individuals not included in the study.
  6. Genotype
    Specific genetic makeup of an individual.
  7. Independent Variable
    Phenomenon that is manipulated by the experimenter in a research study and expected to influence the dependent variable.
  8. Informed Consent
    Ethical requirement whereby research subjects agree to participate in a research study only after they receive full disclosure about the nature of the study and their role in it.
  9. Longitudinal design
    Systematic study of changes in the same individual or group examined over time.
  10. Mental status exam
    Relatively coarse preliminary test of a client's judgement, orientation to time and place, and emotional and mental state; typically conducted duringan initial interview.
  11. Negative Correlation
    Association btwn two variables in which one increases as the other decreases.
  12. Neuroimaging
    Sophisticated computer aided procedures that allow nonintrusive examination of nervous system structure and function
  13. Phenotype
    Observable characteristics or behaviors of an individual
  14. Placebo control group
    In an outcome experiment,a control gropu that does not receive the experimental manipulation but is given an similar procedure with an identical expectation of change, allowing the researcher to assess any placebo effect
  15. Placebo Effect
    Behavior change resulting from the persons expectation of change rather than from the experimental manipulation
  16. Positive Correlation
    Association btwn two variables in which one increases as the other increases
  17. Projective Test
    Psychoanalytically based measures that present ambiguous stimuli to clients on the assumption that their responses will reveal their unconscious conflicts. Lack high reliability and validity
  18. Randomization
    Method for placing individuals into research groups that assures each one of an equal chance of being assigned to any group, to eliminate any systematic differences across gropus.
  19. Reliability
    Degree to which a measurement is consistent ie over time or among different raters
  20. Single-case experimental design
    Research tactic in which an independent variable is manipulated for a single individual, allowing cause-and-effect conclusions but with limited generalizability
  21. Statistical significance
    Probability that obtaining the observed research findings merely by chance is small
  22. Twin study
    In genetics research, comparisons of twins with unrelated or less closely related individuals. If twins, particularly monozygotic twins who share identical genotypes, share common characteristics such as a disorder even if they were reared in different environments, this is strong evidence of genetic involvement in those characteristics.
  23. Validity
    Degree to which a technique actually measures what it purpots to measure.
