Age-related similarities and differences in monitoring spatial cognition

Spatial cognitive performance is impaired in later adulthood but it is unclear whether the metacognitive processes involved in monitoring spatial cognitive performance are also compromised. Inaccurate monitoring could affect whether people choose to engage in tasks that require spatial thinking and also the strategies they use in spatial domains such as navigation. The current experiment examined potential age differences in monitoring spatial cognitive performance in a variety of spatial domains including visual–spatial working memory, spatial orientation, spatial visualization, navigation, and place learning. Younger and older adults completed a 2D mental rotation test, 3D mental rotation test, paper folding test, spatial memory span test, two virtual navigation tasks, and a cognitive mapping test. Participants also made metacognitive judgments of performance (confidence judgments, judgments of learning, or navigation time estimates) on each trial for all spatial tasks. Preference for allocentric or egocentric navigation strategies was also measured. Overall, performance was poorer and confidence in performance was lower for older adults than younger adults. In most spatial domains, the absolute and relative accuracy of metacognitive judgments was equivalent for both age groups. However, age differences in monitoring accuracy (specifically relative accuracy) emerged in spatial tasks involving navigation. Confidence in navigating for a target location also mediated age differences in allocentric navigation strategy use. These findings suggest that with the possible exception of navigation monitoring, spatial cognition may be spared from age-related decline even though spatial cognition itself is impaired in older age.     

证据顺序和证词自信度对学前末期儿童因果推理的影响

开展两个实验探究证据顺序和证词自信水平对5岁儿童因果推理的影响机制。132名和127名5岁儿童分别参与实验1和实验2。实验1发现证据顺序对儿童因果推理的影响表现为近因效应,但证词的自信水平差异不影响儿童的因果推理;实验2发现如果儿童注意到证词的自信水平信息,他们更倾向于在自信证词条件依据证词推断因果关系,证据顺序的影响力被削弱。研究结果说明证据顺序变化导致易受影响的近因效应。     

Narrative skill and testimonial accuracy in typically developing children and those with intellectual disabilities

Children must describe maltreatment coherently for their testimony to be influential in court. We know little about how well children with intellectual disabilities (CWID) describe their experiences relative to typically developing (TD) children, despite CWID's vulnerability to maltreatment. We investigated children's reports of an experienced event and compared coherence in CWID (mild to moderate impairment: 7–11 years) with TD children matched for mental (4–10 years) or chronological age (7–11 years). All children included important markers of narrative coherence in their reports. Children with lower mental ages, particularly those with an intellectual disability, included fewer markers of narrative coherence in their reports than children with higher mental ages. Individual markers of narrative coherence, particularly recall of content, predicted accuracy of testimony and resistance to suggestion even when disability and mental age were taken into account. These findings highlight the importance of helping children to describe their experiences coherently.

通过对513名大学三年级学生的问卷调查, 本研究探讨了全球金融危机背景下大学生经济信心对其职业决策自我效能的影响, 以及内外控制点和主动性人格对此关系的调节作用。结果表明：大学生对经济发展的信心能预测其职业决策自我效能; 内外控制点和主动性人格在此关系中, 分别都起到了调节的作用; 当两者进入同一个调节模型时, 主动性人格的调节作用掩盖了内外控制点的作用。这一调节模型丰富了职业决策自我效能的研究理论, 对高校职业生涯辅导具有借鉴意义。     

Career Preparation: A Longitudinal, Process-Oriented Examination

Preparing for an adult career through careful planning, choosing a career, and gaining confidence to achieve career goals is a primary task during adolescence and early adulthood. The current study bridged identity process literature and career construction theory (Savickas, 2005) by examining the commitment component of career adaptability, career preparation (i.e., career planning, career decision-making, and career confidence), from an identity process perspective (Luyckx, Goossens, & Soenens, 2006). Research has suggested that career preparation dimensions are interrelated during adolescence and early adulthood; however, what remains to be known is how each dimension changes over time and the interrelationships among the dimensions during the transition from high school. Drawing parallels between career preparation and identity development dimensions, the current study addressed these questions by examining the patterns of change in each career preparation dimension and parallel process models that tested associations among the slopes and intercepts of the career preparation dimensions. Results showed that the career preparation dimensions were not developing similarly over time, although each dimension was associated cross-sectionally and longitudinally with the other dimensions. Results also suggested that career planning and decision-making preceded career confidence. The results of the current study supported career construction theory and showed similarities between the processes of career preparation and identity development.     

Healthcare Serial Killers as Confidence Men

Although there is adequate coverage of serial murder in the extant homicide literature, there is a lack of systematic examination of healthcare professionals who serially murder their patients. Using a sample of 58 healthcare serial killers located within North America, South America, and Europe between the years of 1970 and 2010, this study examines notable pre‐offense and post‐offense behaviours of healthcare serial killers. Patterns related to offender aetiology, victim cultivation, crime scene behaviour, and techniques of evasion were explored. The findings from this study suggest that the pre‐offense and post‐offense behaviours of healthcare serial killers can be conceptualised from the theoretical framework of confidence men or ‘con men’. The findings from this study also suggest that healthcare serial killings and offenders who perpetrate them continue to be elusive and warrant additional scholarly attention to reduce their likelihood of engaging in homicide undetected for extended time. Policy implications are also discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Eyewitness Memory for Typical and Atypical Weapons in Cognitive Context

The present research addressed eyewitness memory for weapons, specifically for a modern semi‐automatic pistol and an antique flintlock, in order to address the influence of weapon novelty on recall for the given weapon. Additionally, the effect of explanatory backstory was examined in the same context; respondents were given prior information, which was either consistent or inconsistent with the presence of the flintlock in the scene, in order to gauge the influence of appropriate or inappropriate explanatory cognitive context. Finally, the effects of these variables on line‐up identification of the ‘suspect’ holding the given weapon were addressed. The results showed that weapon type did not influence recall accuracy for given weapons, although explanatory backstory did have a significant effect here, as initially predicted. Both weapon type and explanatory backstory produced significant effects on weapon recall errors, with the exotic weapon and the more prosaic backstory producing larger numbers of mistakes. Neither of these variables was associated with significant differences in line‐up performance. These results indicate the importance of prior cognitive context, as well as the physical appearance of weapons, in a full understanding of eyewitness processing of scenes involving firearms.

An Archival Study of Eyewitness Memory of the Titanic's Final Plunge

A handful of real-life studies demonstrate that most eyewitnesses accurately recall central details (i.e., the gist of what happened) from traumatic events. The authors evaluated the accuracy of archival eyewitness testimony from survivors of the Titanic disaster who witnessed the ship's final plunge. The results indicate that most eyewitness testimony (15 eyewitnesses of 20) is consistent with forensic evidence that demonstrates that the Titanic was breaking apart while it was still on the ocean's surface. Despite the methodological limitations of archival research, the authors provide evidence from a single-occurrence traumatic event (with a large-scale loss of life) that the majority of eyewitnesses accurately recall central details.     

The Impact of Multifaceted Questions on Eyewitness Accuracy Following Forced Fabrication Interviews

Lawyers will frequently use complex-question forms, such as multifaceted questions (single questions that contain both a true and a false proposition), when cross-examining witnesses, and prior research has shown that use of such questions reduces testimonial accuracy. The present study extends this research by using a forced fabrication paradigm (Chrobak & Zaragoza, 2008) to assess how multifaceted questions might affect eyewitness suggestibility after exposure to misleading post-event information. Consistent with prior studies, the use of multifaceted questions led to lower accuracy than simple questions. The novel finding was that multifaceted questions caused larger impairments in performance among fabrication participants (who had earlier been suggestively interviewed), than in control participants (who had not). We also provide preliminary evidence that the impairment caused by multifaceted questions is due to both (a) having to consider two propositions simultaneously, and (b) the shift in question focus from the fabricated event to a true event.     

The impact of self‐confidence on the compromise effect

This research reports an investigation into whether the personality aspect of self‐confidence affects the compromise effect. We hypothesize that highly self‐confident people have greater certainty in making decisions and are more attracted to risk‐taking, which makes them less likely to choose the safe or middle option in a large choice set. The three studies involved are conducted using between‐ and within‐subjects experimental designs. Various product categories are used to generalize the findings. Study 1 looks at purchasing decisions and utilizes three scales of self‐confidence, risk preference, and uncertainty; it demonstrates that consumers with high self‐confidence are less likely to choose a compromise option due to high certainty in their decision‐making. Study 2 discovers that people with low self‐confidence are more likely to choose the middle option in a risky condition than in a nonrisky condition. Study 3 decomposes self‐confidence into general and specific self‐confidence, and reveals that people with low general self‐confidence and low specific self‐confidence are more likely to choose the middle option.
