Individual attitudes toward coerced confessions change perception of confession evidence: why jurors may accept or reject poor-quality confessions.

Wrongful conviction statistics indicate that jurors will accept confession evidence even when it was coerced or contains inconsistent information. While research has considered the role of both inconsistencies and coercion in juror decisions about retracted confessions, little attention has been given to whether juror attitudes toward coerced confessions contribute to perception of suspect guilt. Using an experimental design, we manipulated the presence of inconsistencies and coercion in a fictional confession transcript.

How downplaying or exaggerating crime severity in a confession affects perceived guilt.

This study investigates how judgments of guilt are influenced by factual errors in confessions that either amplify or downplay the severity of the crime. Participants read a confession statement and police report in which either the confession was consistent with the police report, the suspect admitted to a worse crime or the suspect admitted to a lesser crime. Mediation analyses showed that, compared to consistent confessions, both types of directional errors reduced judgments of guilt.

Acute Physical Exercise Can Influence the Accuracy of Metacognitive Judgments.

Acute exercise generally benefits memory but little research has examined how exercise affects metacognition (knowledge of memory performance). We show that a single bout of exercise can influence metacognition in paired-associate learning. Participants completed 30-min of moderate-intensity exercise before or after studying a series of word pairs (cloud-ivory), and completed cued-recall (cloud-?; Experiments 1 & 2) and recognition memory tests (cloud-? spoon; ivory; drill; choir; Experiment 2).

Undermining position effects in choices from arrays, with implications for police lineups.

Choices from arrays are often characterized by position effects, such as edge-aversion. We investigated position effects when participants attempted to pick a suspect from an array similar to a police photo lineup. A reanalysis of data from 2 large-scale field studies showed that choices made under realistic conditions-closely matching eyewitness identification decisions in police investigations-displayed edge-aversion and bias to choose from the top row (Study 1).
