An Article Review of “Memory blindness: Altered memory reports lead to distortion in eyewitness memory” by Cochran et al. (2016)

Introduction:

Cochran et al (2016) provide a case study analysis of the temporal nature of memory in suspect lineups and crimes being investigated by law enforcement. The study involves a longitudinal evaluation of participants that are given evidence of a crime (through slideshows) that allows them to ascertain the criminal act or to choose a suspect in a lineup. At a later time, the participants are given altered information on the crime, which revealed a greatly distorted memory of the crimes that the participants did not remember. This misinformation was an attempt to trick the participants into affirming …show more content…

Multiple-choice questionnaires were used for Experiment 1 to identify false answers. Experiment 2 was partially done online, which allowed the stu8dents to make choices without direct contact with the authors of the study.

Analysis & Results:

Experiment 1 results found that many of the students failed to remember the initial data provided to them at the onset of the study, which provided the effect of misinformation on the memory of the participant: “These analyses revealed a significant main effect for misinformation items, F(1, 163) = 9.89, p = .002, ηp2 = .06, 90 % CI for effect size = [.01, .12] (Cochran et al, 2016, p.721). This data confirms that the students had not retained the original memory of the crimes committed, which resulted in a large-scale choice blindness. In this manner, the multiple –choice segment of this study exposed memory lapses as part of the re-evaluation process of the participant 's memories. Therefore, misinformation was not properly identified in the remembrance of these criminal scenarios. Experiment 2 also proved successful for choice blindness in that the slide show provided for the students at the first-stage was altered in the second-stage. The author’s utilized a “target” and “filler” option for student’s to choose from, yet many of the students did not accurately remember the
