Reconstructing with trace information: Does rapid identification information lead to better crime reconstructions?

Currently, promising new tools are under development that will enable crime scene investigators to analyze fingerprints or DNA‐traces at the crime scene. While these technologies could help to find a perpetrator early in the investigation, they may also strengthen confirmation bias when an incorrect scenario directs the investigation this early. In this study, 40 experienced Crime scene investigators (CSIs) investigated a mock crime scene to study the influence of rapid identification technologies on the investigation. This initial study shows that receiving identification information during the investigation results in more accurate scenarios. CSIs in general are not as much reconstructing the event that took place, but rather have a “who done it routine.” Their focus is on finding perpetrator traces with the risk of missing important information at the start of the investigation. Furthermore, identification information was mostly integrated in their final scenarios when the results of the analysis matched their expectations. CSIs have the tendency to look for confirmation, but the technology has no influence on this tendency. CSIs should be made aware of the risks of this strategy as important offender information could be missed or innocent people could be wrongfully accused.     

The role of group identification in the well-being of Spaniards with gypsy ethnicity

ABSTRACT

Objective: To describe the role of sex, age, educational level and psychosocial group-identification factors in well-being and satisfaction with life. Method: 229 Spanish Gypsies completed a survey of demographic data, psychological well-being, life satisfaction, ethnic identity and the individual’s inclusion of self within the ingroup. Results: (a) only level of studies is related to satisfaction with life; (b) participants with higher scores in ethnic identity reported more well-being and more life satisfaction; and (c) assessment of ethnic belonging affects more areas of well-being than does perception of closeness to the ingroup. Conclusion: objective conditions of deprivation are not related to well-being as reported by the participants; it is important to study how Spanish Gypsies value and perceive their ethnicity in order to predict their well-being and satisfaction with life.     

Re-Examining the Effect of Top-Down Linguistic Information on Speaker-Voice Discrimination

The current study replicated and extended the results from a study conducted by Narayan, Mak, and Bialystok (2017) that found effects of top-down linguistic information on a speaker discrimination task by examining four conditions: rhymes (day-bay), compounds (day-dream), reverse compounds (dream-day), and unrelated words (day-bee). The original study found that participants were more likely to judge two words to be spoken by the same speaker if the words cohered lexically (created lexical compounds such as day-dream) or were phonologically related (rhymes, such as day-bay), but their study contained two limitations: (a) Same- and different-speaker trials were analyzed separately, which obscures effects of response bias, and (b) cross-gender pairs were used in the different-speaker trials, potentially inflating performance. The current study addresses these limitations by including only within-gender trials and by examining sensitivity and bias using signal detection theory. Our results not only provide support of the original study but also provide clear evidence that listeners are biased to judge two words as being produced by the same person when they share either phonological information (rhymes) or lexical-semantic coherence (compounds). Thus, the current study provides an important modified replication of previous research.     

Exploring the nonlinear relationship between challenge stressors and employee voice: The effects of leader–member exchange and organisation-based self-esteem

This study demonstrates how challenge stressor, a job demand that can bring potential gains for employees, influences voice, a change-oriented behaviour challenging the status quo. Specifically, we develop and test an inverted U-shaped relationship that integrates social exchange theory and the framework of resource allocation. Using data collected from 204 employees in Eastern China, we find that the U-shaped relationship between challenge stressor and voice is only emerged at low levels of leader–member exchange. At high levels of leader–member exchange the relationship between challenge stressor and voice is U-shaped. Furthermore, the interactive effect of challenge stressor and leader–member exchange on voice behaviour is mediated by organisation-based self-esteem. The findings of this study have important implications for stress and voice literature.     

脑梗塞、脑出血病人外显与内隐记忆的实验研究

采用模糊字辨认、自由回忆和再认的方法分别测试脑梗塞、脑出血病人（实验组）与无脑部病变者（对照组）外显记忆和内隐记忆成绩。结果发现：实验组较对照组外显记忆降低，内隐记忆存在。提出病人其记忆功能呈外显记忆损害，内隐记忆保存的特点。这种记忆功能的双重性为此种病人记忆功能康复训练提供了新的实验证据。
