Expert psychological testimony on eyewitness reliability before and after Daubert: the state of the law and the science

This article examines the legal and scientific issues inherent in the use of expert psychological testimony on the factors that affect eyewitness reliability. First, the history of the use of such expert testimony is traced. Next, we look at the criteria that state and federal courts have used in determining whether to admit such testimony, as well as the grounds upon which the testimony has been excluded. We then examine the Daubert decision and discuss its implications for the use of expert eyewitness testimony. We conclude by reviewing eyewitness research and research on jury decision-making that is likely to assume new importance in the post-Daubert era.     

Effects of sentential stress and word class upon comprehension in Broca's aphasics

The roles which word class (open/closed) and sentential stress play in the sentence comprehension processes of both agrammatic (Broca's) aphasics and normal listeners were examined with a word monitoring task. Overall, normal listeners responded more quickly to stressed than to unstressed items, but showed no effect of word class. Aphasics also responded more quickly to stressed than to unstressed materials, but, unlike the normals, responded faster to open than to closed class words regardless of their stress. The results are interpreted as support for the theory that Broca's aphasics lack the functional underlying open/closed class word distinction used in word recognition by normal listeners.     

Semantic focus and sentence comprehension.

Reaction time to detect a phoneme target in a sentence was found to be faster when the word in which the target occurred formed part of the semantic focus of the sentence. Focus was determined by asking a question before the sentence; that part of the sentence which comprised the answer to the sentence was assumed to be focussed. This procedure made it possible to vary position of focus within the sentence while holding all acoustic aspects of the sentence itself constant. It is argued that sentence understanding is facilitated by rapid identification of focussed information. Since focussed words are usually accented, it is further argued that the active search for accented words demonstrated in previous research should be interpreted as a search for semantic focus.     

An Exploratory Study of Flow and Motivation in Theater Actors

The purpose of this study was to examine theater actors' experiences of flow and their motivational characteristics. Forty theater students completed revised versions of the Flow State Scale and the Sport Motivation Scale. Participants viewed theater as very challenging, and they performed at a high skill level when having an optimal performance, which occurred almost four times a year. Participants were strongly motivated to participate in theater because the experience of acting was stimulating and exciting. Theater performers also were motivated to perform, to a lesser degree, by external reasons. Patterns of correlations supported the theoretical foundations underlying both flow and motivation. Finally, MANOVA results indicated gender differences and undergraduate versus graduate student status differences.     

The Family Story Technique and Intrafamily Analysis

The Family Story Technique (FST) was devised because of its promising versatility in the assessment among family members of affect, interactional patterns, and outlook on the future. The FST makes use of ten selected TAT cards and a modification of Fine's scoring system. Reliability of scoring in terms of per cent agreement between two scorers was found to range from 67% to 100% for usable categories. Potential usefulness of the FST in family diagnosis and family patterning of interactions is illustrated by a case presentation of family FST scores.     

Facilitating Accuracy in Showup Identification Procedures: The Effects of the Presence of Stolen Property

Law enforcement personnel regularly present suspects to eyewitnesses using showups. In this study, we examined the impact of the presence of stolen property on live showup identification performance. Two hundred seventy university students were exposed to a simulated theft. During the subsequent showup, we manipulated the presence of the target and stolen property. Binary logistic regression analyses indicated that both factors independently predicted the accuracy of identification decisions. Participants were more accurate when the target was in the showup and when the stolen property was present during the identification. Consistent with the item, context, and ensemble theory of recognition, the presence of stolen property led to an increase in sensitivity, suggesting ensemble formation. Future research on showups should continue to examine contextual variables that may lead to changes in sensitivity or criterion shift. Copyright © 2012 John Wiley & Sons, Ltd.     

A Test of Voir Dire as a Remedy for the Prejudicial Effects of Pretrial Publicity1

The present experiment asked two questions: Does prejudicial pretrial publicity produce bias that may impair juror objectivity and, if it does, can extended, defense attorney-conducted voir dire (jury examination procedure) remedy its untoward effects? Subjects were 68 college undergraduates who had or had not read pretrial publicity one week before viewing a mock murder trial. Just prior to viewing the trial, subjects experienced either minimal or extended voir dire. Both pretrial publicity and voir dire produced significant main effects on subjects' perceptions of defendant culpability. Subjects exposed to pretrial publicity perceived the defendant as more culpable than subjects not exposed to pretrial publicity. Subjects who experienced extended voir dire perceived the defendant as less culpable than subjects who experienced minimal voir dire. The interaction between pretrial publicity and voir dire was nonsignificant, indicating that, contrary to our hypothesis, voir dire did not reduce the impact of pretrial publicity.
