PSYCH ASSES

• Internal validity refers to the degree to which we can be confident that changes observed in participants' performance were caused by the independent variable rather than other factors.
• Validity refers to how well an assessment measures what it claims to measure, while reliability refers to the stability of measurement across different times or situations.
• Interrater reliability refers to the consistency between two or more raters who are independently rating the same behavior, event, or condition.
• Interrater reliability refers to the consistency between two or more raters who independently rate the same behavior.
• Personality inventories are self-report questionnaires designed to assess various aspects of an individual's personality, such as traits, behaviors, and emotional patterns.
• The test-retest reliability is the extent to which scores on an instrument are consistent over time.
• The test-retest reliability is the extent to which scores on an assessment remain consistent over time.
• Neuropsychological assessments focus on assessing cognitive abilities, such as memory, attention, and problem-solving, to understand brain-behavior relationships.
• Projective tests are a type of psychological assessment that involves presenting ambiguous stimuli to reveal underlying emotions, thoughts, or conflicts.
• Reliability is important because if two people take the same test at the same time and get very different scores, then there must have been something wrong with one of them (either the person or the test).
• The Hawthorne effect occurs when people change their behavior because they know they are being studied.
• External validity is concerned with whether findings from an experiment are generalizable beyond the specific context in which they occurred, such as the laboratory setting or the sample used.
• Experimenter bias involves researchers unintentionally influencing results due to expectations about what will happen.
• Test-retest reliability is measured over time with the same test given at two points in time.
• Split-half reliability involves dividing the items on a test into two halves and correlating them.
• Test-retest reliability is the extent to which scores on an instrument are consistent over time.
• Split-half reliability involves dividing the test into two halves and correlating them with one another.
• Test-retest reliability is measured by administering the same test twice at different points in time and comparing the results.
• Alternate forms reliability compares scores from one form of a test to another form of the same test.
• Reliability refers to the accuracy and dependability of measurements obtained from psychological tests.
• Validity refers to the degree to which an assessment accurately measures what it claims to measure.
• Validity refers to how well an assessment measures what it claims to measure.
