Boys will be boys: a pre‐line‐up gameplay has beneficial effects on boys' but not girls' identification performance

Fifty children, aged between 4 and 7 years, underwent a sequential photo line‐up procedure in order to identify a man they had met the previous day. Half of the participants engaged in a pre‐procedure gameplay with the female interviewer. It was hypothesised that the game would stimulate rapport building and would ultimately result in an increased performance during the line‐up procedure. The beneficial effect was indeed observed, but only for the male participants. This finding suggests that gameplay may be a fruitful strategy to decrease child witness discomfort and to increase participation. Copyright © 2006 John Wiley & Sons, Ltd.     

Co‐witness feedback in line‐ups

The aim of the current study was to establish whether feedback from a co‐witness concerning their choice of suspect could influence an individual witness' certainty and other testimony‐relevant judgements. Eighty‐two university students and members of the general public viewed a film of a staged mugging in pairs and then made an identification of who they thought was the suspect from a culprit‐absent line‐up (i.e. identification parade). The participants were then required to tell their partner whom they had identified and to fill out a questionnaire with testimony‐relevant questions (e.g. How good a view did you get of the person in the line‐up?). When the pairs of participants agreed on their choice of suspect, their scores on the testimony‐relevant questions tended to be higher than when the pairs did not agree. This shows that co‐witnesses can influence each others' memory reports when giving each other feedback after the identification process. The implications of these findings are discussed.

The effects of post ‐identification feedback and age on retrospective eyewitness memory

Two studies examined the effects of post‐identification feedback, age, and retention interval on participants' memories and beliefs about memories for a videotaped event, as captured by a store surveillance camera. After viewing the video, they were then asked to identify the suspect from a target‐absent photo line‐up. After making their identification, some participants were given information suggesting that their identification was correct, while others were given no information about the accuracy of their identification. In both experiments participants who received confirming feedback indicated they were more confident in their identification, paid more attention to the video, and that they were more willing to testify in court than those who received no feedback. The confidence inflation effects of post‐identification feedback did not vary with retention interval or age. These results are consistent with a position focusing on accessibility, which suggests that witnesses have little or no retrievable recollection of how sure they were at the time of their identification.

A Repeated Forced‐choice Line‐up Procedure Provides Suspect Bias Information with No Cost to Accuracy for Older Children and Adults

In two experiments and one follow‐up analysis, we examined the impact of using a repeated forced‐choice (RFC) line‐up procedure with child and adult eyewitnesses. The RFC procedure divides the identification task into a series of exhaustive binary comparisons that produces not only traditional line‐up information (identification decision and confidence) but also information about witness' selection behavior. Experiment 1 revealed that younger children (6‐ to 8‐year‐olds) struggled with the RFC procedure, while older children (9‐ to 11‐year‐olds) performed as well with the RFC procedure as with a simultaneous procedure (with wildcard). Experiment 2 replicated this comparable performance with adults. Witnesses' suspect selection behavior during the RFC was predictive of identification accuracy for older children and adults. A model examined the additional information provided by the RFC in experiments 1 and 2 and provided evidence that witnesses' patterns of responding can be used to estimate suspect selection bias (a proxy for suspect recognition strength) associated with individual line‐up decisions.

Rule‐Following and Rule‐Breaking: Kierkegaard and Wittgenstein

My aim in this paper is twofold: to establish that Kierkegaard's so‐called theory of the leap strongly anticipates a line of argument that is central to Wittgenstein's so‐called rule‐following considerations; and to begin to show how Kierkegaard's work has fruitful contributions of its own to make to on‐going discussions about rules and rule‐following. The paper focuses throughout on the question of how, if at all, human rule‐following can be distinguished from behaviour that is merely mechanical or instinctual. I identify a central line of argument in Wittgenstein that problematizes this question by establishing the basis our ability to follow rules in our spontaneous responses. I argue that Kierkegaard not only strongly anticipates this line of argument but also offers a distinctive story about what, at bottom, makes the difference between human rule‐following and behaviour that is merely mechanical or instinctual. In a word, on Kierkegaard's story, what makes the difference is: anxiety.     

Turning a blind eye to double blind line‐ups

Although psychologists have urged police officers to use double blind line‐up procedures during their investigations, police officers state that these would be difficult to administer and most have been reluctant to implement this change. Four studies examine whether lay people's judgements about the guilt of a suspect vary according to whether a brief written summary of a case described the identification procedure as double blind or non‐double blind. The effects were all small (and almost all non‐significant). Most people do not treat double blind line‐ups differently from non‐double blind line‐ups when assessing the guilt of a defendant. Either police investigators should stop using this biased method or police investigators and others in the judicial system (e.g. jurors, judges) should be informed of this bias when evaluating results from any line‐up.

Servicescapes: The role that place plays in stay‐at‐home mothers’ lives

Over the past decade, increasing attention has been paid to gender‐related consumption behaviour. However, a relative gap in our knowledge still exists when it comes to understanding the changes that occur as a result of motherhood and how this may influence their interactions in the retail environment. The purpose of this article is to explore stay‐at‐home mothers’ experiences in the servicescape to gain a better understanding of how they associate with servicescapes during this transitional period, how they use retail space to suit their needs, and how they use retail space to negotiate their role as a stay‐at‐home mother. Five stay‐at‐home mothers with children younger than 5 years were provided with disposable cameras and asked to photograph servicescapes that they visited regularly. Over a 1‐year period, they were interviewed several times, and photo‐elicitation techniques were used throughout the interviewing process. The results of this study suggest that when consumers undergo role or identity changes, certain places can be used to smooth this process. Not only can the retail environment be used as a coping mechanism for stay‐at‐home mothers, it can also be viewed as a “second place” as opposed to a “third place”, thus enabling isolated consumers to feel connected with the outside world. Last, this study highlights the temporal dimensions of place. Throughout one's lifetime, one will form attachments to and patronise different places, which will evolve and change as individuals, accordingly, take on different roles and identities.

Perception of line‐up suggestiveness: effects of identification outcome knowledge

Research on the hindsight bias has shown that knowledge of an event outcome makes the observed outcome appear more predictable than it does in the absence of outcome knowledge. It was hypothesised that perceptions of the suggestiveness of a line‐up would be similarly influenced by knowledge of a witness' identification decision, with a positive identification of the suspect increasing, and a negative non‐identification decreasing, perceived suggestiveness. The ratings of undergraduate students (N = 50) in Experiment 1 showed the predicted influence of positive outcome, whereas negative outcome had no demonstrable influence. In contrast, Experiment 2, conducted with police trainees (N = 126) and with the line‐up presented in the context of a criminal investigation, partially supported the predicted influence of negative, but not positive, outcome. The discrepant findings are discussed in terms of the cognitive mechanisms underlying the hindsight bias and the implications for real‐life judgements of line‐up suggestiveness.

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.     

The Positive Influence of Creating a Holistic Facial Composite on Video Line‐up Identification

Witnesses to a crime may be asked to create a facial composite of the offender from memory. They may then view a suspect in a police line‐up. Previous research on this topic has found both recognition impairment and enhancement following composite construction. In Experiment 1, creator‐participants employed the holistic facial composite system system EFIT‐V or the feature‐based E‐FIT system to create a single composite, and in Experiment 2, creators constructed up to three EFIT‐Vs. In both experiments, facial composite creators were one‐and‐a‐half times more likely than non‐composite creating controls to make correct target identifications from a video line‐up. No between condition effects were found in target‐absent trials in Experiment 1. The development of holistic facial composite systems has enhanced suspect identification rates in police investigations, and these results suggest that the use of such a system can also have a positive influence on a composite‐creating witness' later recognition of the suspect.

Place‐value understanding in number line estimation predicts future arithmetic performance

In multi‐digit numbers, the value of each digit is determined by its position within the digit string. Children's understanding of this place‐value structure constitutes a building block for later arithmetic skills. We investigated whether a number line estimation task can provide an assessment of place‐value understanding in first grade. We hypothesized that estimating the position of two‐digit numbers requires place‐value understanding. Therefore, we fitted a linear function to children's estimates of two‐digit numbers and considered the resulting slope as a measure of children's place‐value understanding. We observed a significant correlation between this slope and children's performance in a transcoding task known to require place‐value understanding. Additionally, the slope for two‐digit numbers assessed at the beginning of grade 1 predicted children's arithmetic performance at the end of grade 1. These results indicate that the number line estimation task may indeed constitute a valid measure for first‐graders' place‐value understanding. Moreover, these findings are hard to reconcile with the view that number line estimation directly assesses a spatial representation of numbers. Instead, our results suggest that numerical processes involved in performing the task (such as place‐value understanding) may drive the association between number line estimation and arithmetic performance.     

Predicting Self‐Confident Behaviour with Implicit and Explicit Self‐Esteem Measures

The present research compared the validity of popular direct and indirect measures of self‐esteem in predicting self‐confident behaviour in different social situations. In line with behavioural dual‐process models, both implicit and explicit self‐esteem were hypothesized to be related to appearing self‐confident to unacquainted others. A total of 127 participants responded to the Rosenberg Self‐Esteem Scale, the Multidimensional Self‐Esteem Scale, and an adjective scale for measuring explicit self‐esteem (ESE). Participants' implicit self‐esteem (ISE) was assessed with four indirect measures: the Implicit Association Test (IAT), the name‐letter task (NLT), and two variants of an affective priming task, the reaction‐time affective priming task (RT‐APT) and the error‐based affective priming task (EB‐APT). Self‐confident behaviour was observed in four different social situations: (i) self‐introduction to a group; (ii) an ostracism experience; (iii) an interview about the ostracism experience; and (iv) an interview about one's personal life. In general, appearing self‐confident to unknown others was independently predicted by ESE and ISE. The indirect measures of self‐esteem were, as expected, not correlated, and only the self‐esteem APTs—but not the self‐esteem IAT or the NLT—predicted self‐confident behaviours. It is important to note that in particular the predictive power of the self‐esteem EB‐APT pertained to all four criteria and was incremental to the ESE measures.

The Weapon Focus Effect in Target‐Present and Target‐Absent Line‐Ups: The Roles of Threat,Novelty, and Timing

When an eyewitness suffers an impairment of memory for a perpetrator because the criminal used a weapon during the crime, this impairment is called the weapon focus effect. The literature is split on how this arises: Some implicate the narrowing of attentional cues to the weapon because the arousal of the victim increases, whereas others claim that the weapon is a novel object in most everyday contexts, and novel objects demand more attention than contextually appropriate ones. The current study employed a simulated crime paradigm featuring a normal, novel, or threatening object. Timing of the object's presentation was manipulated such that it was visible before, after, or during the time when the culprit's face was visible. Target‐present and target‐absent line‐ups as well as retrospective questions were administered. Both the novel object and the weapon resulted in increased mistaken identifications in target‐absent line‐ups. Structural equation modeling suggested that object novelty mediated this effect.

On‐line ostracism affects children differently from adolescents and adults

This research examines adults', and for the first time, children's and adolescents' reaction to being ostracized and included, using an on‐line game, ‘Cyberball’ with same and opposite sex players. Ostracism strongly threatened four primary needs (esteem, belonging, meaning, and control) and lowered mood among 8‐ to 9‐year‐olds, 13‐ to 14‐year‐olds, and adults. However, it did so in different ways. Ostracism threatened self‐esteem needs more among 8‐ to 9‐year‐olds than older participants. Among 13‐ to 14‐year‐olds, ostracism threatened belonging more than other needs. Belonging was threatened most when ostracism was participants' first experience in the game. Moreover, when participants had been included beforehand, ostracism threatened meaning needs most strongly. Gender of other players had no effect. Practical and developmental implications for social inclusion and on‐line experiences among children and young people are discussed.     

Proper‐Function Moral Realism

A common line of thought in contemporary metaethics is that certain facts about the evolutionary history of humans make moral realism implausible. Two of the most developed evolutionary cases against realism are found in the works of Richard Joyce and Sharon Street. In what follows, I argue that a form of moral realism that I call proper‐function moral realism can meet Joyce and Street's challenges. I begin by sketching the basics of proper‐function moral realism. I then present what I take to be the essence of Street's and Joyce's objections, and I show how proper‐function realism answers them.     

Predicting changes in children's self‐perceptions from playground social activities and interactions

The general aim of this study was to examine the concurrent and longitudinal (6 month) associations between 8‐ to 9‐year‐old children's (N=75) social activities and interactions during recess and their self‐perceptions, and to test for gender differences in those associations. The underlying rationale was that recess provides an important, and hitherto unstudied, context in which children's experiences can impact on their views of themselves. Consistent with this proposition, several of the playground variables were significantly correlated concurrently with participants' self‐perceptions regarding social acceptance, and, particularly, athletic competence. Even stronger evidence came from the longitudinal analyses which indicated that group size positively predicted changes in social acceptance and global self‐worth scores; network positively predicted changes in physical appearance and global self‐worth scores; rule games positively predicted changes in athletic competence, physical appearance and global self‐worth scores; conversation negatively predicted changes in athletic competence, and alone negatively predicted changes in physical appearance and global self‐worth scores. Several significant gender differences were obtained: the association between rule games and changes in social acceptance was negative for girls but positive for boys; a positive association between conversation and social acceptance was evident among girls but not boys; and a negative association between conversation and changes in athletic competence was evident among boys but not girls. The theoretical and practical implications of these results are discussed.     

Post‐identification feedback effects: Investigators and evaluators

We investigated the effects of post‐identification feedback and viewing conditions on beliefs and interviewing tactics of participant‐investigators, crime reports of participant‐witnesses and participant‐evaluators' credibility judgments of the witnesses. Study 1 participants assumed the roles of witness and investigator (N = 167 pairs). Witnesses' view of a simulated crime video was manipulated by distance from viewing monitor: 2 or 9 ft. Participants made a line‐up identification and received either positive feedback or no feedback. Significant effects for witnesses and investigators were associated with viewing condition and post‐identification feedback. Interviews between investigator‐witness pairs were videotaped. Investigators asked more positive, leading questions when they were led to believe that the witness had identified the suspect. In Study 2 evaluators (N = 302) viewed the witness‐investigator interviews. Viewing condition had no effect on judgments of witness credibility but positive post‐identification feedback led evaluators to judge witnesses as more credible than witnesses who received no feedback.

The Cost of Detecting Deception: Judging Veracity Makes Eyewitnesses Remember a Suspect Less Accurately but With More Certainty

The current study extends previous research demonstrating the detrimental effects of divided attention during encoding on eyewitness memory. Previous data indicate that judging the veracity of a suspect causes witnesses to scrutinize him or her carefully and requires relatively high cognitive effort. We therefore hypothesized that performing this task while simultaneously observing the suspect should impair witnesses' memory for his or her appearance and message while ironically inflating their certainty and other testimony‐relevant judgments. Our results supported these predictions. Moreover, inducing witnesses to be suspicious about the suspect's truthfulness (Experiment 1) and motivating them to judge veracity as accurately as possible (Experiment 2) amplified the memory impairment effect and further increased several testimony‐relevant ratings. Additionally, compared with witnesses who incorrectly identified the suspect in a line‐up, those who made a correct decision expressed greater certainty about their line‐up accuracy and also provided higher ratings on some other testimony‐relevant measures.

The Mystery Man Can Help Reduce False Identification for Child Witnesses: Evidence from Video Line‐ups

It is well established that children (as young as 5 years) can correctly identify a target from a target present (TP) line‐up as accurately as adults; however, when shown a target absent (TA) line‐up, children make more false identifications. In the present study, children aged 5–7 and 8–11 years viewed a film of a staged theft, then 1–2 days later were shown either a TP or TA video line‐up. Half of the witnesses viewed line‐ups that included a ‘mystery man’ (a black silhouette with a white question mark), which they could select if they did not recognise anyone from the line‐up. When the ‘mystery man’ was present in the line‐up, there were significantly fewer false identifications for the TA line‐ups. This study shows that including a silhouette in a video line‐up can help reduce false identifications for children as young as 5 years of age, without reducing correct identifications.

Mother–child interaction and sleep regulation in one‐year‐olds

The regulation of sleep–wake states is controlled not only by biological mechanisms but by care‐giving context as well. In this study the association between mother–child relationship and the infant's sleep was examined. Thirty‐seven 12‐month‐olds and their mothers participated in a 10‐minute laboratory play episode. The dyadic interaction was coded with the Early Parent–Child Relational Assessment (Clark, 1985) and with the Emotional Availability scales (Biringen, Robinson, & Emde, 1993). The child's sleep was measured at home with a small‐computerized activity monitor. Although mothers' behavior was not related to the child's sleep, infants who were more responsive in the play episode woke up more frequently compared to infants who were less involved in the interaction. The link between social‐emotional competency and fragmented sleep, among nonrisk infants, could be an age‐related phenomenon. ©2001 Michigan Association for Infant Mental Health.
