Identification accuracy for single‐ and double‐perpetrator crimes: Does accomplice gender matter?

There is an important mismatch between empirical research on the accuracy of eyewitness identification and the real world of criminal investigation. Most research models single‐perpetrator crimes, but in the real world, most crimes involve multiple perpetrators. This study examined how the number of perpetrators affects eyewitness identification by manipulating the gender of accomplices. Observers viewed a video of a staged crime. The crime was committed by a male or female perpetrator, who was presented alone or with an accomplice of the same or the opposite gender. The observers were then asked to identify the perpetrators from target‐present or target‐absent line‐ups. The results revealed a double‐perpetrator disadvantage, which was manifested in reduced identification accuracy on target‐present line‐ups. Importantly, however, the gender of the perpetrator or the accomplice had no effect on this disadvantage. This double‐perpetrator disadvantage is attributed to the need to divide attention between two concurrent people, compared to single‐culprit crimes, rather than an impairment of visual encoding processes. The implications of these findings are discussed.     

Partner‐AMP and well‐being: Evidence for an implicit secure base script?

The current research presents an adapted Affect Misattribution Procedure (AMP) to assess the aspects of the relational schema of romantic partners that are difficult to verbalize and tests the prediction that a positive implicit image of the partner constitutes a psychological resource that increases well‐being. In Study 1, the partner‐AMP predicted well‐being in student participants even after controlling for explicit partner attitudes and socially desirable responding. In Study 2, the partner‐AMP was assessed in women with a recent history of physical abuse and a control group. As expected, the partner‐AMP was related to group membership and predicted well‐being over and above explicit partner attitudes and battering experience. The results are compatible with the notion of an implicit secure base schema.     

Is regret for inaction relatively self‐enhancing?

Previous accounts of regret suggest that people report greater regret for inaction than for action because the former is longer lasting and more painful than the latter. We suggest instead that the tendency for people's greatest regrets to concern inaction more than action may be due to the relatively self‐enhancing nature of regrets for inaction. In Study 1 we asked people to think about their greatest recent regret and to code it as being due to action or inaction. In Study 2 participants described their greatest regret from across their entire life. In both studies we observed an inaction effect only amongst individuals high in self‐esteem (HSE). In Study 2 we found that the inaction effect was confined to HSE people whose greatest regret was personal in nature. These results support the claim that regret for inaction is relatively self‐enhancing and suggest that the inaction effect found in real‐life regrets may be due, in part at least, to the self‐enhancement goals of HSE individuals.

Is interpersonal and institutional e‐trustworthiness equally important in consumer e‐trust development? Implications for consumers' e‐trust building behaviours

Trust is a widely studied phenomenon across numerous disciplines. E‐trust researchers have conducted a vast number of studies, but despite extensive interest in the issue, there are only few studies that concentrate on how consumers build e‐trust. Furthermore, consumer e‐trust is seen to be a function of both interpersonal and institutional e‐trustworthiness, but only limited number of attempts have been conducted to study the relative importance of interpersonal and institutional e‐trustworthiness in consumer e‐trust development process. The present article seeks to improve this situation by studying how consumers' perceived interpersonal and institutional e‐trustworthiness influence their intention to build e‐trust. The results of the study suggest that consumers build e‐trust actively, and the development of e‐trust is not only based on trustees' behaviour. Moreover, the results indicate that interpersonal e‐trustworthiness is more important than institutional e‐trustworthiness in consumers' e‐trust building.

Delusion‐proneness or miscomprehension? A re‐examination of the jumping‐to‐conclusions bias

Previous research has consistently shown that individuals with delusions typically exhibit a jumping‐to‐conclusions (JTC) bias when administrated the probabilistic reasoning ‘beads task’ (i.e., decisions made on limited evidence and/or decisions over‐adjusted in light of disconfirming evidence). However, recent work in this area has indicated that a lack of comprehension of the task may be confounding this finding. The purpose of the present study was to evaluate the influence of task administration, delusion‐proneness, and miscomprehension on the elucidation of the JTC bias. A total of 92 undergraduate university students were divided into one of two task conditions (i.e., non‐computerised and computerised) and were further identified as either delusion‐prone or non‐delusion‐prone and as comprehending or non‐comprehending the task. Overall, 25% of the sample demonstrated a JTC bias, and just over half made illogical responses consistent with a failure to comprehend the task. Qualitative evidence of comprehension revealed that these ‘illogical responses’ were being driven by a misunderstanding of task instructions. The way the task was administrated and levels of delusion‐proneness did not significantly influence JTC. However, miscomprehending participants were significantly more likely to exhibit the bias than those who did comprehend. These results suggest that miscomprehension rather than delusion‐proneness may be driving the JTC bias, and that future research should include measures of miscomprehension.     

Does a short self‐compassion intervention for students increase healthy self‐regulation? A randomized control trial

The primary aim of this study was to examine the effects of a two‐week self‐compassion course on healthy self‐regulation (personal growth self‐efficacy and healthy impulse control) and unhealthy self‐regulation (self‐judgment and habitual negative self‐directed thinking) in university students. We also examined the effects on self‐compassion, anxiety and depression. Students (N = 158, 85% women, mean age = 25 years) were randomized to an intervention group and a waiting‐list control group in a multi‐baseline randomized control trial. Healthy self‐control was measured by the Personal Growth Initiative Scale (PGIS) and the Self‐Control Scale; unhealthy self‐control was measured by the Non‐judgement subscale from the Five‐Facet Mindfulness Questionnaire (reversed) and the Habit Index of Negative Thinking (HINT). Secondary outcomes were measured by the State‐Trait Anxiety Inventory (STAI‐trait), the Major Depression Inventory (MDI), and the Self‐Compassion Scale (SCS). A 2 × 3 repeated measures analysis of variance (ANOVA) showed gains for the intervention‐group in personal growth self‐efficacy and healthy impulse‐control and reductions in self‐judgment and habitual negative self‐directed thinking, as well as increases in self‐compassion and reductions in anxiety and depression. After all participants had completed the course, the groups were combined and repeated measures ANOVAs showed that changes remained at six‐month follow‐up for personal growth self‐efficacy, self‐judgment and habitual negative self‐directed thinking; as well as for self‐compassion, anxiety and depression. Concluding, a short self‐compassion course seems an effective method of increasing self‐compassion and perceived control over one's life for university students, as well as increasing mental health.     

Do Americans Have a Preference for Rule‐Based Classification?

Six experiments investigated variables predicted to influence subjects’ tendency to classify items by a single property (rule‐based responding) instead of overall similarity, following the paradigm of Norenzayan et al. ( 2002 , Cognitive Science), who found that European Americans tended to give more “logical” rule‐based responses. However, in five experiments with Mechanical Turk subjects and undergraduates at an American university, we found a consistent preference for similarity‐based responding. A sixth experiment with Korean undergraduates revealed an effect of instructions, also reported by Norenzayan et al., in which classification instructions led to majority rule‐based responding but similarity instructions led to overall similarity grouping. Our American subjects showed no such difference and used similarity more overall. We conclude that Americans do not have a preference for rule responding in classification and discuss the differences between tasks that reliably show strong rule or unidimensional preferences (category construction and category learning) in contrast to this classification paradigm.     

How strong is the comparison‐to‐the‐strongest heuristic?: An empirical test of the comparison‐ to‐the‐strongest heuristic in probability judgment1,2

Abstract: Windschitl and Wells (1998 ) proposed that the pairwise comparison between the focal and strongest alternative outcomes plays an important role in probability judgment. However, their studies did not control the effects of alternative outcomes other than the strongest one. This article tested whether only the strongest alternative outcome would affect probability judgment, using a variable selection method in a multiple regression analysis. Study 1 reanalyzed the results of Windschitl and Young (2001 ) and showed that only the strongest alternative outcome affects probability judgment. In Study 2, a new experiment was conducted to modify the methodological problems in Study 1. The results of Study 2 were identical to those of Study 1. All these results consistently supported the comparison hypothesis.     

Does parental mental health moderate the effect of a telephone and internet‐assisted remote parent training for disruptive 4‐year‐old children?

This study explores the moderators affecting the success of an Internet‐based and telephone assisted remote parent training intervention and compares them to an educational control group. We prospectively identified 464 parents who reported at a health check that their 4‐year‐old children showed elevated levels of externalizing behavior. The moderators explored included parental attention deficit and hyperactivity disorder (ADHD) and parental distress. The dependent variables were child externalization scores and self‐reported parenting skills. The measures were completed at baseline, six and 12‐months follow‐up. The 232 families randomized to active treatment received 11 Internet‐based training sessions with weekly phone calls from a coach. The other 232 families had access to a website that provided general positive parenting advice and one 45‐minute phone‐call from a coach. Using hierarchical linear models, we explored if the parental ADHD or parental distress modified the treatment effects on child externalizing behavior or parenting skills. The results showed that none of the independent variables moderated intervention effects on child externalizing behavior or parenting skills. The lack of significant moderator effects could have been due to the treatment's personalization, the format's flexibility and adaptability to when and how the parents wanted to complete the sessions or the relatively low levels of ADHD and parental distress among the participants.     

Can parent‐to‐parent consultation improve the effectiveness of the Maudsley model of family‐based treatment for anorexia nervosa? A randomized control trial

Objective: This paper describes a preliminary randomized control trial that explores the use of parent‐to‐parent consultations as a potential augmentation to the Maudsley model of family‐based treatment for anorexia. Method: Twenty families were randomized into two groups, ten receiving standard treatment and ten receiving an additional parent‐to‐parent consultation early on in treatment. Measures of parental efficacy (Parents versus Anorexia Scale), patient distress (Depression Anxiety and Stress Scale) and percentage ideal body weight were taken each week. The effects of parent‐to‐parent consultations on parental efficacy and weight were analysed by comparing data with random effects models. Results: A significant treatment effect was found, with parent‐to‐parent consultations leading to a small increase in the rate of weight restoration. Conclusion: This practice has the potential to enhance weight restoration when included in the Maudsley model of family‐based treatment for anorexia nervosa. Research that tests more potent forms of intervention may also have merit.     

Disfluency Meets Cognitive Load in Multimedia Learning: Does Harder‐to‐Read Mean Better‐to‐Understand?

In a series of four experiments, we examined the impact of disfluency in multimedia learning by testing contrasting predictions derived from disfluency theory and cognitive load theory against each other. Would a less legible text be beneficial to learning when accompanied by pictures, and what would be the role of less legible pictures? Students (N = 308) learned with text and pictures that were either easy‐to‐read (i.e., fluent) or harder‐to‐read (i.e., disfluent) about how a toilet flush works (Experiments 1–3) and about how lightning develops (Experiment 4). In line with disfluency theory, a disfluent text led to better performance in the transfer test and to more invested mental effort in Experiment 1. However, these beneficial effects could not be replicated in Experiments 2, 3, and 4, leaving open questions regarding the stability and generalizability of the disfluency effect, and thus raising concerns regarding its impact for educational practice.

Off‐Target? Changing Cognitive‐Based Attitudes

Researchers argue that the effectiveness of cognitive versus affective persuasive appeals depends in part on whether the appeal is congruent or incongruent with a primarily cognitive or affective attitude base. However, considerable research suggests that these persuasion effects may hold only for predominantly affective attitudes and not cognitive attitudes. Indeed, results of Experiment 1 show that the relative effectiveness of congruent relative to incongruent persuasion appeals holds for brands with predominantly affective associations, but not those with predominantly cognitive associations. Experiment 2 explores one reason for this anomalous finding: Cognitive attitudes may be relatively impervious to persuasive appeals because the probability of targeting the specific attribute on which the cognitive attitude is based is smaller. The results are supportive, showing that significant persuasion effects are found when the specific beliefs on which cognitive attitudes are based are taken into account. However, these effects only occur under conditions of low cognitive load and not high cognitive load where resources for the cognitive processing of the appeals are limited. We discuss the implications of the research for the role of attitude structure in understanding persuasion effects and the interplay of affective and cognitive elements in persuasion processes.     

Is ‘culture’ a justifiable variable for market segmentation? A cross‐cultural example

This paper investigates whether culture can be used to segment a market. Using Indians, resident in Britain (British Indians) as an example, previous research suggests that culture's manifestation within buyer behaviour provides sufficient evidence to justify its use as a market segment variable. Using brown goods (television sets, video equipment, music systems etc) a comparative quantitative study examined the impact of a range of cultural values upon the buying behaviour of British Indians and British Caucasians, to identify significant differences between the two. Although a significant difference was found, the amount of similarity between the two sample groups suggests culture should not be used as a segmentation variable. This research has implications for organisations seeking to develop ethnic minority orientated marketing strategies. Copyright © 2003 Henry Stewart Publications.     

Co‐sleeping: Help or hindrance for young children's independence?

This study investigated the relationship between sleep arrangements and claims regarding possible problems and benefits related to co‐sleeping. Participants were 83 mothers of preschool‐aged children. Data were collected through parent questionnaires. Early co‐sleepers (who began co‐sleeping in infancy), reactive co‐sleepers (children who began co‐sleeping at or after age one), and solitary sleepers were compared on the dimensions of maternal attitudes toward sleep arrangements; night wakings and bedtime struggles; children's self‐reliance and independence in social and sleep‐related behaviours; and maternal autonomy support. The hypothesis that co‐sleeping would interfere with children's independence was partially supported: solitary sleepers fell asleep alone, slept through the night, and weaned earlier than the co‐sleepers. However, early co‐sleeping children were more self‐reliant (e.g. ability to dress oneself) and exhibited more social independence (e.g. make friends by oneself). Mothers of early co‐sleeping children were least favourable toward solitary sleep arrangements and most supportive of their child's autonomy, as compared to mothers in other sleep groups. Reactive co‐sleepers emerged as a distinct co‐sleeping sub‐type, with parents reporting frequent night wakings and, contrary to early co‐sleepers, experiencing these night wakings as highly disruptive. Implications for parents and pediatricians are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

How do symbols affect 3‐ to 4‐year‐olds' executive function? Evidence from a reverse‐contingency task

In two experiments, 330 3‐ to 4‐year‐olds competed for stickers in a game in which the optimal response strategy was to point to an empty box that their opponent would receive in order to obtain a baited box for themselves. When the baited box contained stickers, children showed a strong tendency to point at the baited box and therefore lose the stickers to their opponent. In Experiment 1 children performed better when the number of stickers to be won was represented with one of five different types of symbol: numerals, number words, dots, a photograph or sweets. In Experiment 2 children transferred their improved performance in symbolic conditions to non‐symbolic conditions. These findings suggest that symbols enable children to formulate an efficient response strategy, and that this effect may be qualitatively different in children from the effect of symbols in non‐human primates.     

Verbal self‐instructions in task switching: a compensatory tool for action‐control deficits in childhood and old age?

This study examined the influence of verbal self-instructions on age differences in task switching. Task-switching ability, measured as the difference between performance in single-task blocks and in mixed-task blocks in which participants switch between two tasks (mixing costs), increases during childhood and decreases in old age. To measure the influence of language on task switching, we compared conditions in which participants either (a) named the next task to be performed (i.e. task-relevant verbalization), (b) verbalized words not related to the task at hand (i.e. task-irrelevant verbalization), or (c) did not verbalize (control condition). Results indicated that mixing costs were substantially reduced under task-relevant verbalization and increased under task-irrelevant verbalization. Moreover, age-related differences in mixing costs were increased when the use of inner speech was disrupted and were reduced when participants performed task-relevant verbalization. These findings suggest that verbal self-instructions are a useful tool for retrieving the next task goal and for reducing action-control deficits in younger children and older adults.     

Self‐esteem and culture: Differences in cognitive self‐evaluations or affective self‐regard?

Although people from East Asian countries consistently report lower self-esteem than do those from Western countries, the origins of this difference are unclear. We conducted two studies to illuminate this issue. Study 1 found that Chinese participants appraised themselves less positively than American participants on a cognitive measure of self-evaluations, but cultural differences were absent on a measure of affective self-regard. Moreover, cultural differences in global self-esteem were eliminated once cognitive self-evaluations were statistically controlled. Study 2 found that cultural differences in modesty underlie cultural differences in cognitive self-evaluations. These findings suggest that Chinese feel as positively toward themselves as Americans do, but are less inclined to evaluate themselves in an excessively positive manner.
