Document Summary

Two types of memory retrieval: recall reporting details of previously witnessed event/person, recognition reporting whether current information is the same as previous information. Variety of research methods: archival data, naturalistic environments, laboratory simulations. Estimator variables variables that cannot be changed (age of witness, lighting, etc. ) System variables variables that can vary (questioning techniques, lineup procedure) Recall of the event: two forms of recall: Open ended recount without being prompted. Direct question witnesses asked specific questions: examining recall information. Recognition of the culprit: typically police lineup (photos, voice, etc. , accuracy, type of errors. Limited ability to collect information: interrupted witnesses during free recall, asked short, specific questions, asked off-topic questions, asked leading questions. (cid:862) (cid:373)ashed(cid:863) vs. (cid:862)(cid:272)o(cid:374)ta(cid:272)ted(cid:863: reported higher speeds. Implications: false or added information provided after event can influence memory, subtle phrasing differences (smashed vs. hit) may bias witnesses responses. Three theories: acceptance hypothesis, source misattribution hypothesis, memory impairment hypothesis.
