Deck 8 Flashcards
The mean and standard deviation of the WAIS; also the mean and standard deviation of a z-score
100; 15
ANOVA
Analysis of variance that is used when more than two t scores need to be compared.. A one-way ANOVA is used with independent variable, two-way with two independent variables, etc.
The placebo effect
An effect in research where the dependent variable is influenced by the mere idea of an independent variable. Often controlled for in research design by suing a sugar pill in a second experimental group.
The Hawthorne effect
Also known as the observer effect- just knowing there is someone watching may improve performance in research.
The Rosenthal effect
Also known as experimenter expectancy- the experimenter’s beliefs may lead the experimenter to treat a participant in a particular way to yield results.
The Halo effect
Occurs when a trait that is not being measured has influence on a trait that is.
Longitudinal Study
A type of developmental research that follows the same group of people over time
Cross-sectional study
A type of developmental research that compares individuals of differing age groups at the same time.
.70
The generally acceptable level for most psychological attributes is a reliability coefficient of .70
WAIS- IV
Wechsler Adult Intelligence Scale. The generally accepted standard for intelligence testing. The mean is 100 and the standard deviation is 15. Applicable for test subjects from ages 16-90
WISC-V
Wechsler intelligence scale for children. Applicable for intelligence testing for test subjects from ages 6-16
WPPSI-IV
Wechsler Preschool and primary scale for intelligence. Applicable for intelligence testing for test subjects from ages 2-7
Alfred Binet and David Simon (Binet-Simon)
Created the first intelligence test (Binet-Simon) after he was requested by a government commission to come up with a way to detect children with significantly below-average intelligence and mental retardation.
David Wechsler
Developed the WAIS and WISC and WPPSI as the predominant measures of intelligence testing.
Likert Scale
A psychometric scaling often used with questionnaires. Typically features 3-5 responses (Strongly agree-strongly disagree)
Free Test
A test that is subjective in nature, the participant has the opportunity to craft an answer based on questions or stimuli presented (Rorschach, essay, TAT)
Forced test
A test that requires the participant to choose from a pre-selected set of response sets. (Survey, questionnaire)
Rorschach Test
Associated with psychodynamics: Also referred to as the inkblot test. Is a projective test designed to allow the participant to project unconscious thoughts or feelings onto the images.
Ability Tests
Measures only the participants ability to problem solve, does not measure content or what the individual has been able to complete or achieve thus far.
Achievement tests
Measures the extent to which an individual has acquired certain information, or mastered certain skills
Aptitude Tests
Measures the ability to learn or develop a proficiency in a particular area.
Spiral tests
a test in which the items become progressively more difficult as you move through the test. Most intelligence tests are spiral.
