AP PSYCHOLOGY

Detailed explanation-1: -A low ecological validity means that the findings of the research can not be generalized and applied to real-life situations.

Detailed explanation-2: -Ecological validity examines, specifically, whether the study findings can be generalized to real-life settings; thus ecological validity is a subtype of external validity.

Detailed explanation-3: -Lacks ecological validity – due to the involvement of the researcher in manipulating and controlling variables, findings cannot be easily generalised to other (real life) settings, resulting in poor external validity.

Detailed explanation-4: -Studies whose findings demonstrate high ecological validity often occur in more natural settings-that is, environments with features that are more familiar to the participants or settings that mask part or all of the participants’ perception that an experiment is taking place.
