“He Couldn't Have Done It,He Was With Me!”: The Impact of Alibi Witness Age and Relationship

Undergraduate participants who conducted a simulated police investigation were presented with either a child (6 years old) or adult (25 years old) alibi witness, who was either the son or neighbor of the participant's suspect. Replicating previous research, participants were more likely to believe the adult neighbor alibi witness than the adult son. In fact, an alibi provided by the adult son actually proved detrimental to that suspect, as participants thought the suspect was more likely to be guilty after viewing an alibi provided by the adult son. However, child‐provided alibis reduced perceptions of suspect guilt, regardless of that child's relationship to the suspect. The child alibi witnesses were also viewed by the participants as more credible than the adult witnesses. Copyright © 2011 John Wiley & Sons, Ltd.     

Unconscious creativity: When can unconscious thought outperform conscious thought?

Recent research suggests that unconscious thought is superior to conscious thought in many cognitive domains. In this article, we show that the duration of unconscious thought has an inverted-U shaped relationship with creativity performance. Unconscious thought is, thus, unlikely to provide creative advantage over conscious thought when deliberation duration is either short or long. However, when deliberation duration is of a moderate length, the creative output of unconscious thought surpasses that of conscious thought. Furthermore, the superiority of unconscious thought pertains only to the novelty dimension of creativity, but not the appropriateness dimension. These findings not only shed light on the powers and limits of unconscious thought but also illuminate the importance of calibration in utilizing unconscious thought to boost creativity.     

Order and Strength Matter for Evaluation of Alibi and Eyewitness Evidence

We explored the effects of presentation order and evidence strength on participants acting as investigators in a criminal context. Participants evaluated evidence and suspect guilt in a study in which alibi witness and eyewitness evidence of varying strength, presented in different orders, were compared. In contrast to research on the confirmation bias, which suggests that evidence presented early distorts subsequent evaluations of evidence, the present findings suggest that under certain circumstances, evidence received most recently can have a greater impact on decision‐making. Recency effects were observed most frequently when recent evidence was particularly strong and often when it contradicted previously encountered strong evidence. The impact of recency extended beyond the impact of evidence and to evaluations of the credibility of individual pieces of evidence. Copyright © 2013 John Wiley & Sons, Ltd.     

Some problems of counter‐inductive policy as opposed to inductive

The article is concerned with the practicalist attempt to ‘solve’ the problem of induction. The point of departure is the concept of counter‐induction introduced by Max Black and his refutation of practicalism. If we arc not to beg the question whether induction yields knowledge of the future, Max Black asserts, there is a symmetry between induction and counter‐induction as methods. The main point of the article is to show that this assertion is false, at least when induction and counter‐induction are compared as regards their relations to hypo‐thetico‐deductive method. As regards these relations, there is a striking asymmetry. The author tries to establish the following conclusion: A theory can agree with all future data and yet be false because it does not agree with all past data. If we are not to be in a position where our theories are necessarily falsified either by past or future data, we must use induction rather than counter‐induction.     

Some but not all dispreferred turn markers help to interpret scalar terms in polite contexts

In polite contexts, people find it difficult to perceive whether they can derive scalar inferences from what others say (e.g., does “some people hated your idea” mean that not everyone hated it?). Because this uncertainty can lead to costly misunderstandings, it is important to identify the cues people can rely on to solve their interpretative problem. In this article, we consider two such cues: Making a long Pause before the statement, and prefacing the statement with Well. Data from eight experiments show that Pauses are more effective than Wells as cues to scalar inferences in polite contexts—because they appear to give a specific signal to switch expectations in the direction of bad news, whereas Well appears to give a generic signal to make extra processing effort. We consider the applied value of these findings for human–human and human–machine interaction, as well as their implications for the study of reasoning and discourse.     

Joint attention in term and preterm infants at 12 months corrected age: the significance of gender and intervention based on a randomized controlled trial

This study tested the effects of optimized neonatal mother–infant transactions on joint attention performance at 12 months. Surviving infants <2000 g from a geographically defined area were randomly assigned to a preterm intervention (n = 71) or preterm control group (n = 69). Comparisons were made between preterm groups, secondary with a term group (n = 75). Joint attention was measured using the Early Social Communication Scales. Preterm intervention infants scored significantly higher than preterm control infants on elements Initiating Joint Attention (p < 0.05), Initiating Object Requests (p < 0.05), and Responding to Social Interaction (p < 0.0005). Intervention was not associated with performance on elements Responding to Joint Attention, or on Responding to Requests. ELBW infants scored significantly lower than VLBW and LBW infants on imperative functions. Girls outperformed boys on all communication elements. An intervention implemented during the neonatal period can be of advantage for certain aspects of joint attention performance in preterm infants.     

Coping with condom embarrassment

This study assesses the embarrassment associated with purchasing, carrying, storing, using and disposing of condoms. It incorporates coping theory into the investigation of embarrassment by analysing the strategies individuals use to cope with embarrassment during condom purchase. The results of a survey show that individuals are embarrassed at various stages related to condom use. Purchasing condoms elicits the most embarrassment, followed by carrying and disposing, while using and storing are the least embarrassing. To cope with their embarrassment while purchasing condoms, people use multiple cognitive and behavioural coping strategies, with embarrassed people using more strategies. Both embarrassment and the number of strategies used decrease with age and experience. It appears that embarrassment associated with condoms remains a barrier to condom acquisition and consistent condom use, particularly among young adult populations. Coping strategies help individuals to bridge the gap between embarrassment and use.     

A survey of mental health care provider's and managed care organization attitudes toward, familiarity with, and use of group interventions

Managed Care has had a significant impact on delivery systems for mental health services. Direct and indirect persuasion to provide more cost-effective treatments has been one consequence. The cost-saving qualities and the effectiveness of group interventions have produced clear expectations for an increased use of therapy groups. This study compared perceptions and uses of group treatments on a national sample of managed care organizations and mental health providers. Because group psychotherapy encompasses such a broad definition, five specific types of group interventions were defined: problem-focused homogenous, process-oriented heterogeneous, psycho-educational, self-help, and short-term groups. Implications of differences and similarities between directors of managed care organizations and treatment providers are examined and discussed across five response categories (familiarity/training, perceived effectiveness, likelihood of reimbursement/referral, daily use, and expectation for future use).
