Category 1
efficacy wherein scores obtained from a measure behave exactly the same as the variable itself
What is construct validity?
efficacy wherein a relationship between scores obtained from two different measures of the same construct
What is convergent validity?
any feature of a study that gives away the purpose of the study
What is demand characteristic?
lustering of scores at the low end of a scale, allowing little possibility of decreases
what is the floor effect?
participant attempt to follow experimental instructions to the letter
what is the faithful subject role?
efficacy wherein two different measures of the same construct exhibit a relationship between scores
what is test-retest reliability?
efficacy wherein scores from a measure are directly related to scores from an established measure
what is concurrent validity
participant modification of behavior in response to participating in a research study
what is reactivity
efficacy wherein scores obtained from a measure accurately predict behavior according to a theory
what is predictive validity
concern whether a measure superficially appears to measure what it claims to measure
what is face validity
efficacy demonstrated by using two different methods to measure two different constructs
what is divergent validity?
accuracy established by comparing scores obtained by using two alternate versions of a measure
what is parallel-forms reliability
degree of agreement between two observers who simultaneously record measurements of a behavior
what is inter-rater reliability
the accuracy obtained by calculating consistency between scores on two halves of measure items
type of measurement on which the categories are organized sequentially
what is the ordinal scale
record of a physiological activity, such as heart rate
what is the physiological measure?
a record obtained by the direct observation of an individual's actions
what is behavioral measure
lack of agreement between two measures
what is desynchrony
clustering of scores at the high end of a scale, allowing little possibility of increases
what is the ceiling effect
influence on the findings of a study from the experimenter's expectations
what is experimenter bias
study in which the researcher does not know the predicted outcome for any specific participant
what is single-blind research?
study in which both the researcher and the participants are unaware of the predicted outcome
what is double-blind research
any feature of a study that gives away the purpose of the study
what is demand characteristic
participant tendency to respond in a way that is expected to corroborate investigators' hypothesis
what is good subject role
participant tendency to respond in a way that is expected to refute investigators' hypothesis
what is negativistic subject role
