Although the Internet is a beneficial tool, some youth are at risk for being victimized by Internet predators. School counselors are in a unique position to assist in efforts to prevent online victimizations because of their continual interaction with students, parents, and other school faculty. This article provides school counselors with information about youth Internet use; risk factors associated with online victimizations; and recommendations to assist youth, parents, and families in improving Internet safety practices.  相似文献

In the UK video parades are the preferred method of identification employed in criminal cases. This policy implementation has been employed with little or no evidence concerning its validity. The reported research examines the effect of new video technology on children's identification evidence. The study compared 7–9 and 13–15‐year olds' ability to make identifications from either video or static photo lineups. Two hundred and fifteen participants witnessed a live event and then after a delay of 2–3 days viewed a target present (TP), or target absent (TA) video or photo lineup. For video and photo TP lineups, correct responses did not differ as a function of age. Video lineups produced lower rates of false identifications for the TA lineups, but only for adolescent witnesses. It is concluded that there is nothing contra‐indicated in the use of video identification procedures with children, and possibly certain benefits can accrue from its use.

This study examines the use of mental context reinstatement (MCR) and a virtual licence plate (VLP) in licence plate recall. In Experiment 1, 104 participants viewed a videoed crime featuring a vehicle bearing an ‘old‐style’ UK licence plate. Group 1 (control) recalled the video unaided by MCR or VLP. Group 2 used MCR, Group 3 used VLP, Group 4 used MCR + VLP. Compared with control, group 2 demonstrated a significant 38% increase in correct plate characters recalled, group 3 a non‐significant 23% increase, and group 4 a significant 69% increase. Group 4 also demonstrated a significant 50% increase in correct information recalled regarding the crime. In Experiment 2, 48 participants viewed a videoed crime featuring a vehicle bearing a ‘new‐style’ UK plate. Results replicated Experiment 1. The MCR + VLP group demonstrated a significant 124% increase in correct licence plate recall and a significant 52% increase in correct information recalled regarding the crime.

Research on residential diversification has mainly focused on its negative impacts upon community cohesion and positive effects on intergroup relations. However, these analyses ignore how neighborhood identity can shape the consequences of diversification among residents. Elsewhere, research using the Applied Social Identity Approach (ASIA) has demonstrated the potential for neighborhood identity to provide social and psychological resources to cope with challenges. The current article proposes a novel model whereby these “Social Cure” processes can enable residents to cope with the specific challenges of diversification. We present two studies in support of this model, each from the increasingly religiously desegregated society of postconflict Northern Ireland. Analysis of the 2012 “Northern Ireland Life and Times” survey shows that across Northern Ireland, neighborhood identity impacts positively upon both well‐being and intergroup attitudes via a reduction in intergroup anxiety. A second custom‐designed survey of residents in a newly mixed area of Belfast shows that neighborhood identification predicts increased well‐being, reduced intergroup anxiety, and reduced prejudice independently of group norms and experiences of contact. For political psychologists, our evidence suggests a reformulation of the fundamental question of “what effects do residential mixing have on neighborhoods?” to “how can neighborhood communities support residents to collectively cope with contact?”  相似文献

Research on residential diversification has neglected its impact on neighbourhood identity and overlooked the very different identity-related experiences of new and existing residents. The present research examines how incoming and established group members relate to their changing neighbourhood in the increasingly desegregated city of Belfast, Northern Ireland. Thematic analysis of interviews with 24 residents (12 Protestant long-term residents, 12 Catholic incomers) from an increasingly mixed neighbourhood identified asymmetrical concerns and experiences: Incomers reported undergoing an ‘identity transition’ between local communities, while long-term residents faced an ‘identity merger’ within their neighbourhood. Where their identity concerns diverged, emergent intergroup perceptions of the residents were negative and divisive; where they accorded, positive intergroup perceptions and a shared neighbourhood identity evolved. From this, we propose a Social Identity Model of Residential Diversification (SIMRD) to encourage future research into how different identity concerns shape emergent intergroup dynamics between long-term residents and incomers within diversifying neighbourhoods.  相似文献

The origin of color categories has been debated by psychologists, linguists and cognitive scientists for many decades. Here, we present the first electrophysiological evidence for categorical responding to color before color terms are acquired. Event-related potentials were recorded on a visual oddball task in 7-month old infants. Infants were shown frequent presentations of one color (standard) interspersed with infrequent presentations of a color that was either from the same category (within-category deviant) or from a different category (between-category deviant) to the standard. Differences in the event-related potentials elicited by the stimuli were found that were related to the categorical relationship of the standard and the deviant stimuli. The data are discussed in relation to the processes that underlie categorical responding in infancy, as well as the debate about the origin of color categories in language and cognition.  相似文献

The ability to remain vigilant over long periods of time is critical for many everyday tasks, but controlled studies of visual sustained attention show that performance declines over time when observers are required to respond to rare stimulus events (targets) occurring in a sequence of standard stimulus events (nontargets). When target discrimination is perceptually difficult, this vigilance decrement manifests as a decline in perceptual sensitivity. We examined whether sudden-onset stimuli could act as exogenous attentional cues to improve sensitivity during a traditional sustained attention task. Sudden-onset cues presented immediately before each stimulus attenuated the sensitivity decrement, but only when stimulus timing (the interstimulus interval [ISI]) was constant. When stimulus timing was variable, exogenous cues increased overall sensitivity but did not prevent performance decline. Finally, independent of the effects of sudden onsets, a constant ISI improved vigilance performance. Our results demonstrate that exogenous attention enhances perceptual sensitivity during vigilance performance, but that this effect is dependent on observers’ being able to predict the timing of stimulus events. Such a result indicates a strong interaction between endogenous and exogenous attention during vigilance. We relate our findings to a resource model of vigilance, as well as to theories of endogenous and exogenous attention over short time periods.  相似文献

Three major categories of prejudice have been identified in this article: Conscious/Intentional, Conscious/Unintentional, and Unconscious/Unintentional. Prejudice plays a large role in the development of our children, and through exposure to and understanding of the development of prejudice, the strength that it holds can be understood and diminished.  相似文献
