Out with the old? The role of selective attention in retaining targets in partial report

In the partial-report task, subjects are asked to report only a portion of the items presented. Selective attention chooses which objects to represent in short-term memory (STM) on the basis of their relevance. Because STM is limited in capacity, one must sometimes choose which objects are removed from memory in light of new relevant information. We tested the hypothesis that the choices among newly presented information and old information in STM involve the same process—that both are acts of selective attention. We tested this hypothesis using a two-display partial-report procedure. In this procedure, subjects had to select and retain relevant letters (targets) from two sequentially presented displays. If selection in perception and retention in STM are the same process, then irrelevant letters (distractors) in the second display, which demanded attention because of their similarity to the targets, should have decreased target report from the first display. This effect was not obtained in any of four experiments. Thus, choosing objects to keep in STM is not the same process as choosing new objects to bring into STM.     

Increased realism in eyewitness confidence judgements: the effect of dyadic collaboration

This study investigated to what extent, and under what circumstances, pair collaboration influences the realism in eyewitness confidence in event memory. The participants first saw a short film clip and then confidence rated their answers to questions on its content. A condition (the Individual–Pair condition) where individual effort preceded pair collaboration showed better calibration compared with a condition (the Simple Pair condition) where no individual effort took place. Furthermore, within the Individual–Pair condition, better calibration, and lower overconfidence, were found in the pair phase compared with the individual phase. The eyewitnesses in the Individual–Pair condition made more realistic judgements of the total number of questions answered correctly. In a control experiment no effect on realism in confidence was found when individuals performed the same task twice. The improved realism in the Individual–Pair condition may partly be explained in terms of the increased accuracy and lowered confidence found for such items where the pair members' had given different answers in the individual phase, and by a risky shift effect for such items where they had given the same answer.

Repeated interrogations: verbal and non‐verbal cues to deception

The major aim of this study was to investigate to what extent verbal and non‐verbal features of liars' and truth‐tellers' behaviour change during the course of repeated interrogations. After seeing a staged event, 24 suspects (12 liars and 12 truth‐tellers) were interrogated three times over a period of 11 days. In terms of the non‐verbal features, and in line with our prediction, we found that the liars displayed significantly fewer smiles, self‐manipulations, pauses, and less gaze aversion than truth‐tellers. Furthermore, over time the initial differences between liars' and truth‐tellers' non‐verbal behaviour increased for smiles, gaze aversion and pauses. In addition, we found that the cue ‘richness of detail’—the most indicative verbal marker for truth as given in previous research—had no discriminative power at any of the interrogation sessions. Finally, and in contrast to beliefs held by supposed expert lie‐catchers (e.g. judges and police officers), truthful and deceptive statements were found to be equally consistent over time. The psycho‐legal implications of the above findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

Politics for Learning or Learning for Politics?

It is argued that political democracyand citizenship should not be taken as primarygoals within university education. Instead theauthor argues for a notion of ``academicdemocracy' with the overall goal or ethos oflearning together. Moreover it is argued that``learning' then should be understood accordingto ``practical traditions of knowledge', whichmeans that truth is not the ultimate goal. Theultimate goal is practices that lead to thegood of men and women.     

Evaluation of a Swedish version of the Job Stress Survey

The present study assesses and evaluates the psychometric properties of a Swedish version of the Job Stress Survey (JSS; Spielberger, 1991; Spielberger & Vagg, 1999). This instrument is constructed to measure generic sources of occupational stress encountered by employees in a wide variety of work settings, settings that often result in psychological strain. The JSS was administered to metal assembly industry workers and medical service personnel in northern Sweden (n= 1186). The exploratory factor analysis showed that there is a high similarity between the present Swedish version and the original American version. Internal reliabilities of the scales, as well as test-retest reliabilities were shown to be high, and concurrent validity, as examined by comparisons with the Perceived Stress Questionnaire Index (Levenstein et al., 1993) was found to be satisfactory. The consistency of these findings is discussed with particular focus on groups of employees, gender, and cross-cultural evaluations.     

The ‘elasticity’ of criminal evidence: a moderator of investigator bias

This study examined investigators' perceptions of the reliability of incriminating and exonerating evidence of different types. Police trainees in the role of investigators read the background of a homicide case and then received a piece of evidence that either confirmed or disconfirmed their prior suspicion against the suspect. Despite identical objective characteristics of the evidence, participants rated the disconfirming (vs. confirming) evidence as less reliable and generated more arguments to question its reliability. This asymmetrical scepticism was stronger for participants judging witness evidence, compared to DNA and photo evidence, supporting the hypothesis that different types of evidence vary in ‘elasticity’—the extent to which subjective interpretations can be justified. Interestingly, the observed effects were not limited to the specific evidence in the case, but also affected the ratings of the type of evidence in general, suggesting that reliability criteria for witness information are highly malleable and sensitive to contextual influences.

Internet‐initiated sexual abuse: adolescent victims' reports about On‐ and Off‐line sexual activities

The purpose of the present study was to investigate how adolescent girls, who had been sexually (on‐ and off‐line) deceived and abused by an Internet hebephile, reported about these acts. As we had access to documentation of 68 girls' conversations (i.e. chat logs) and involvement with the perpetrator, we were able to gauge what the victims reported during the police interview against this detailed documentation. In contrast with findings from previous research, the majority of victims reported about the off‐line activities (real‐life meetings) with the perpetrator. However, the victims omitted and/or denied more of the on‐line activities, specifically the more severe sexual on‐line acts (sending nude photos and participating in sexual web shows). There is probably a gap between what the victims reported and what they presumably remembered about the on‐line activities. Factors that might have affected the victims' pattern of reports are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

To challenge and to be challenged – teachers collective learning in higher education

Critical analyzing and reflective competence are essential objectives in all higher education. In academic professional education, it is a challenge for the teacher to support and develop the student´s critical reflection of both academic and placement studies. The aim of this study is to identify the characteristics of the teacher role and the challenges of the reflective seminar within higher education. Data were gathered through group interviews and analyzed with a phenomenological hermeneutic approach. The result shows four themes; the experience of control and uncertainty, building trust and challenging ideas, the alternation between closeness and distance, and the parallel processes of supervising learning and being in a learning state. One conclusion is that the seminar teaching practice stimulates a collegial learning environment. This practice promotes the teachers pedagogical and didactical competence and an open attitude to each other´s teaching practice.     

“I think you did it!”: Examining the effect of presuming guilt on the verbal output of innocent suspects during brief interviews

Innocent suspects interviewed by a guilt‐presumptive versus innocence‐presumptive or neutral interviewer may tend more to display non‐verbal behaviours which neutral judges consider indicative of guilt. We examined the effects of interviewer's presumption of guilt on innocent mock suspects' alibis. Participants (N = 90) provided an alibi to convince an interviewer of their innocence of a theft after she implied that she believed that they were guilty or innocent or that she had no belief about their veracity. On the basis of existing conflicting findings for suspects' verbal behaviour during accusatory interviews, we predicted that alibis in the guilt‐belief condition would contain the highest or lowest number of correct details with overall higher or poorer accuracy rates, respectively. Although participants perceived the interviewer's presumptive approach, the number of correct details provided and accuracy rates of alibis did not differ significantly between conditions. We propose explanations to these findings and future research paths.
