Document Summary

Lecture 4 research methods in developmental psychopathology. Naturalistic observation involves observing individual in the real world . Descriptive observational and involves a single case study. Non-experimental explores relationships, no manipulative variables. Experimental manipulate variables: randomized subjects are allocated into groups randomly, quasi-experimental subjects are not randomly assigned. The case study is a descriptive, non- experimental method. It focuses on the individual, detailed report of the person and treatment used, provides a hypothesis, tries to bridge gaps between research and practice: poor reliability, validity, and generalizability. Correlational studies non-experimental studies that describe the relationship between two variables without exposing the participants to manipulation. Single-case experimental designs experimental manipulation with a single participant. Multiple baseline designs when reversal designs are not appropriate, more than one behaviour is of interest, same behaviour in different settings, multiple participants. Retrospective longitudinal research but one year later.
