Effects of anxiety on handgun shooting behavior of police officers: a pilot study

Abstract

The current pilot study aimed at providing an initial assessment of how anxiety influences police officers’ shooting behavior. Seven police officers participated and completed an identical shooting exercise under two experimental conditions: low anxiety, against a non-threatening opponent, and high anxiety (HA), against a threatening opponent who occasionally shot back using colored soap cartridges. Measurements included shooting accuracy, movement times, head/body orientation, and blink behavior. Results showed that under HA, shooting accuracy decreased. Underlying this degradation of performance, participants acted faster and made themselves smaller to reduce the chance of being hit. Furthermore, they blinked more often, leading to increases in the amount of time participants had their eyes closed. Findings provide support for attentional control theory, hereby also pointing to possible interventions to improve police officers’ shooting performance under pressure.     

Health Outcomes by Closeness of Sexual Abuse Perpetrator: A Test of Betrayal Trauma Theory

Summary

In this chapter, practicing attorney Brooks Cooper illuminates how the legal tradition of applying different standards to the ad-missibility of expert and lay opinions as evidence in litigation complicates delayed-discovery sexual abuse cases. Admissibility standards have long been a source of controversy, and recent developments in law, such as the pre-trial evidentiary hearings that invoke the “gatekeeper” function of the judge under the standard enunciated in Daubert v. Mer-rell-Dow Pharmaceuticals, have become a favored strategy by the defense in an effort to bar delayed memory testimony by characterizing it as the product of unreliable science. To overcome this litigation hurdle, Mr. Cooper contextualizes the present controversy in the history of scientific evidence admissibility, tracing emerging trends in judicial opinion on scientific evidence from expert witnesses from the 1923 case Frye v. United States through the present, and offers strategies and techniques to maintain admissibility of the evidence before and during all phases of the trial.     

Size and orientation cue figure-ground segregation in infants

ABSTRACT

Adult perceivers segregate figure from ground based on image cues such as small size and main axis orientation. The current study examined whether infants can use such cues to perceive figure-ground segregation. Three- to 7-month-olds were familiarized with a pie-shaped stimulus in which some pieces formed a?+?and other pieces formed an x. The infants were then presented with a novelty preference test pairing the?+?and x. The bases for the pieces forming the?+?or x were size and orientation (Experiment 1), size (Experiment 2), and orientation (Experiment 3). In each experiment, infants responded as if they recognized as familiar the shape specified by small size, main axis orientation, or their combination. Control conditions showed that infant performance could not be attributed to spontaneous preference. The findings suggest that infants can achieve figure-ground segregation based on some of the same cues used by adults.     

Knowing what to look for: Voice affects face race judgements

The study examined the effect that auditory information (speaker language/accent: Japanese or French) had on the processing of visual information (the speaker's race: Asian or Caucasian) in two forced-choice tasks: Classification and perceptual judgement on animated talking characters. Two (male and female) sets of facial morphs were constructed such that a 3-D head of Caucasian appearance was gradually morphed (in 11 steps) into one of Asian appearance. Each facial morph was animated in association with spoken French/Japanese or English with a French/Japanese accent. To examine the auditory effect, each animation was played with or without sound. Experiment 1 used an Asian or Caucasian classification task. Results showed that faces heard in conjunction with Japanese or a Japanese accent were more likely to be classified as Asian compared to those presented without sound. Experiment 2 used a same or different judgement task. Results showed that accuracy was improved by hearing a Japanese accent compared to without sound. These results were discussed in terms of the voice information acting as a cue to assist in organizing and attending to face features.     

Does home life interfere with or facilitate job performance?

The study examines whether home life influences inrole and extrarole job performance in positive or negative ways. We hypothesized that home resources would have a direct positive effect on job performance, and an indirect relationship through home–work facilitation (HWF). Home demands were predicted to negatively affect job performance through home–work interference (HWI). These hypotheses were tested on a sample of 190 male employees. In addition to employees' self-reports, wives rated their own home demands and resources (these were used as controls), and co-workers rated the men's HWI, HWF, and job performance. Results partially supported the hypotheses. Men's home demands and resources were related to self-rated HWI and HWF respectively, whereas co-worker ratings of HWI and HWF were associated with inrole and extrarole performance respectively. Men's home resources also had a direct relationship with inrole and extrarole performance. There was no convincing evidence that HWI and HWF acted as mediators in these relationships. Taken together, the positive influence of home life on job performance was stronger than the negative one.     

Not all job demands are equal: Differentiating job hindrances and job challenges in the Job Demands–Resources model

This study aimed to integrate the differentiation between two types of job demands, as made in previous studies, in the Job–Demands Resources (JD-R) model. Specifically, this study aimed to examine empirically whether the differentiation between job hindrances and job challenges, next to the category of job resources, accounts for the unexpected positive relationships between particular types of job demands (e.g., workload) and employees' work engagement. Results of confirmatory factor analyses supported the differentiation between the three categories of job characteristics in two samples (N ₁ = 261 and N ₂ = 441). Further, structural equation modelling confirmed the hypotheses that job hindrances associate positively with exhaustion (i.e., the main component of burnout) and negatively with vigour (i.e., the main component of work engagement). Job resources displayed the reversed pattern of relations. Job challenges were positively related to vigour. Rather unexpectedly, they were unrelated to exhaustion. Based on these findings, we discuss the importance of the differentiation between different types of job demands in the JD-R model for both theory and practice.     

Role salience and support as moderators of demand/conflict relationships in China

This study examined the effects of role demand on both work–family conflict and family–work conflict, and the moderating effects of role salience and support on these relationships. Based on 391 dual-career (managerial and blue-collar employees) couples from a Taiwanese company in China, the results of this survey study showed clear gender differences in the patterns of relationships observed. For men, the most important demands that negatively impacted on work–family conflict were frequency of overtime and frequency of socializing for work purposes (yingchou), and supervisory support buffered the negative impact of frequent overtime. For women however, strong supervisory support and low work role salience were more important for reducing work–family conflict, and there was no significant main effect found for any of the role demand factors. Furthermore, women with high work role salience were more likely to feel the impact of yingchou on work–family conflict. In the family domain, the most influential demand for men was hours spent on household tasks, but for women, it was the frequency of family-related leave. Interestingly, males reported higher family role salience than females and spouse support intensified rather than buffered the positive impact of hours spent on household tasks on family–work conflict for males.     

Cognitive styles and person–environment fit: Investigating the consequences of cognitive (mis)fit

There is currently considerable interest in the key elements of person–environment fit to understand vocational behaviour and to develop strategic human resource management practices. In the light of this interest, we wanted to investigate (1) whether people within similar functions have similar cognitive styles, and (2) what the consequences of cognitive (mis)fit are on three work attitudes, using two large-scale databases (N = 24,267 and N = 2,182). We identified a knowing-oriented cognitive climate in finance, information technology (IT), and research and development (R&D) functions; a planning-oriented cognitive climate in administrative and technical and production functions; and a creating-oriented cognitive climate in sales and marketing functions and general management. Furthermore, we found that the relationship between people's cognitive styles and work attitudes (i.e., job satisfaction, job search behaviour, and intention to leave) does not depend on the cognitive climate in which they work. However, we did find that people with a higher creating style on average score higher on intention to leave and job search behaviour in comparison with people who score lower on the creating style, irrespective of the cognitive climate they are working in. The cognitive climate also partially affects job satisfaction and intention to leave after controlling for cognitive styles. In summary, cognitive styles and cognitive climate seem to have separate influences on people's work attitudes. Our findings are relevant for selection and recruitment policies of organizations and in the context of training, job design, and workforce planning.     

No time for compromises: Age as a moderator of the relation between needs–supply fit and job satisfaction

In the light of the current demographic change, organizations need to be aware of factors influencing job satisfaction of older workers in order to maintain high motivation and commitment. The present study addresses this issue by examining the moderating effect of age on the relationship between needs–supply fit and job satisfaction. Based on the general assumption that older workers are more sensitive to circumstances that threaten their well-being (Carstensen, 2006 Carstensen, L. L. 2006. The influence of a sense of time on human development. Science, 312: 1913–1915. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), we hypothesize that older as compared to younger workers should react more negatively to a misfit between their needs and available job supplies. Hence, older as compared to younger workers should report lower levels of job satisfaction when experiencing a misfit between needs and supplies. This hypothesis was tested in a sample of 471 employed workers from different occupational areas. Results confirmed our hypothesis for four out of five domains of needs–supply fit: Significant three-way interactions between needs, supply, and age were observed. The present result that older as compared to younger workers react more strongly to needs–supply misfits additionally underlines the benefits of considering age-related changes in work values and needs in age-sensitive human resource practices.     

Web-based recruitment in the Millennial generation: Work–life balance,website usability,and organizational attraction

In this digital era, traditional recruitment efforts have increasingly been supplemented with or replaced by recruiting applicants on the Web. Concurrently, organizations are increasingly adapting to younger individuals from the Millennial generation as they enter the workforce. We combine these salient issues to examine Web-based recruitment of the Millennial generation by assessing predictors of organizational attraction. Using a sample of Millennials (N = 493), we found that perceptions of both work–life balance and website usability incrementally predicted attraction, when controlling for perceptions of other organization characteristics. In addition, person–organization fit mediated these relationships. These findings speak to the importance of examining how aspects of Web-based recruitment influence Millennial applicants.
