PSYB45H3 Chapter Notes - Chapter 9: Cumbersome, Internal Validity, Dependent And Independent Variables
Document Summary
Indirect assessment procedures: have the advantages of being convenient, not requiring an inordinate amount of time and potentially providing info about covert behaviors, disadvantage those providing info might not remember relevant observations accurately or have biases. This is called reactivity: when people know that their behavior is being observed either by others or by self-recording, their observed behaviors might change. Chapter 21: direct behavioral assessment: what to record and how. Characteristics of behavior to be recorded: topography of behavior specific movements involved in making the response. This is the length of time that behavior occurs within some period. Intensity of behavior usually use instruments: stimulus control of behavior, typically concerned w/ preverbal and verbal skills. Chapter 22: doing behavior modification research: attempts to demonstrate convincingly that it was the treatment, not some uncontrolled variable that was responsible for any change in the target behavior.
