Research since the 1960s has consistently found that lay volunteers are better at helping suicidal callers than professionals. Yet, professional degrees are increasingly becoming requirements for helpline workers. In our first study, we conducted post hoc comparisons of U.S. helplines with all professional paid staff, all lay volunteers, and a mix of both, using silent monitoring and standardized assessments of 1,431 calls. The volunteer centers more often conducted risk assessments, had more empathy, were more respectful of callers, and had significantly better call outcome ratings. A second study of five Quebec suicide prevention centers used silent monitoring to compare telephone help in 1,206 calls answered by 90 volunteers and 39 paid staff. Results indicate no significant differences between the volunteers and paid employees on outcome variables. However, volunteers and paid staff with over 140 hours of call experience had significantly better outcomes. Unlike the United States, Quebec paid employees were not required to have advanced professional degrees. We conclude from these results and previous research that there is no justification for requiring that suicide prevention helpline workers be mental health professionals. In fact, the evidence to date indicates that professionals may be less effective in providing telephone help to suicidal individuals when compared to trained lay volunteers.  相似文献

The tendency to discount future prospects in lieu of smaller immediate outcomes is known as temporal discounting. The current work used eye‐tracking methodology to examine attentional processing to different elements of choice during an intertemporal decision task. Our findings reveal that those who tend to prefer the immediate option demonstrate attentional biases that were predictive of choice. When losses were at stake, selective attention biases also predicted unique variance in self‐report measures of risk taking, impulsivity, and self‐control beyond what was accounted for by a discounting parameter (k), a typical method for summarizing intertemporal choice data. Overall, our findings suggest that eye‐tracking measures of selective attention may allow for a better theoretical understanding of the mechanisms and processes involved in intertemporal choice.

Although previous research indicates that both employment and adult attachment style have an influence on academic achievement, the interaction of these two factors has not been clarified. The purpose of this study was to investigate the moderating effect of adult attachment style on the relationship between employment status and first semester academic achievement in higher education. A sample of 378 freshman college students answered a series of questionnaires (Academic Amotivation Inventory, the Relationship Questionnaire and demographic), and their high school averages and first semester academic results were obtained from the Registrar’s office. The Analysis of covariance showed that employment status (having employment vs. no employment) and adult attachment style of students (secure vs. dismissing) strongly interacted in predicting academic achievement (first semester average adjusted for high school average, perceived financial burden, and amotivation). More specifically, the first semester averages of secure students with or without employment, and that of dismissing students without employment was indistinguishable. However, dismissing students with employment had significantly lower first semester averages than the secure students. This study showed that dismissing students entering postsecondary education who also have employment are at greater risk of academic difficulties than students with a secure attachment style.  相似文献

The quantity and distribution of child abuse material (“child pornography”) has substantially risen since the advent of the internet facilitated access. Due to the international character of the associated delinquency prosecution is confronted with several difficulties. In 2003 the European Union established a framework agreement to legally combat child pornography. The market for child abuse material is profitable, as production is comparably cheap. The number of convictions for relevant crimes varies but is generally still on a high level, even though reporting of relevant contents is decreasing. Providers and users might have switched to less controllable internet platforms. The physical and/or psychological sequelae for victims of child pornography are serious and ongoing. Studies show that compared to hands-on-offenders users of child exploitation material are generally younger, better educated and less often have a criminal record. Some of them (10–25?%) fulfill the diagnostic criteria of pedophilia. A child pornography offender’s risk of committing a hands-on-offence seems to be increasing with the diagnosis of pedophilia and antisocial personality traits. According to existing data, individuals whose only criminal record refers to illegal pornography seem to be at low risk for future offending with child abuse (0.2–6.6?%). Offenders who were already convicted for child abuse have a higher risk for re-offending when consuming (deviant) pornography. Several cognitive behavioral treatment manuals exist, however accurate diagnostic assessment and indication are required.  相似文献

We critically review the empirical evidence published by van Berkum, Brown, and Hagoort (1999a, b) against syntax-first models of sentence parsing. According to van Berkum et al., discourse factors and word gender information are used instantaneously to guide the parser. First, we note that the density of the experimental trials (relative to fillers) and the slow presentation rate of the van Berkum et al. design seem likely to have elicited the use of tactics involving rapid reanalysis of the material. Second, we present new data from a questionnaire study showing that the grammatical gender information of a relative pronoun in Dutch is often completely ignored, even during the wrap-up phase at the end of the sentence.  相似文献

This study uses neuroimaging methods to identify patterns of brain activation among sport fans in reaction to team stimuli. In a whole-brain analysis without selected regions in advance, the purposes were to identify the structures involved when fans are exposed to positive, neutral, and negative events and to learn what events activate more limbic networks. A total of 53 individuals participated in and functional magnetic resonance imaging experiment involving the presentation of videos in various situations. Findings indicate the activation of the cingulate gyrus and other structures of the limbic system, as the hippocampus and parahippocampus. We also found involvement of the ventral tegmental area of the reward system. Additionally, brain activity in emotional regulation and memory areas were more influenced by positive than neutral and negative videos. It was also found the involvement of other areas not directly included in the limbic or reward systems. This study provides the neural basis of fan reactions to team-related stimuli. Sport clubs should be aware that negative content seems to be suppressed from emotional memory and positive videos trigger more emotion and memory areas than neutral and negative videos.  相似文献

The context of intergroup relations in Aotearoa/New Zealand was investigated using perceptions of history by Maori (Polynesian‐descended) and Pakeha (European‐descended) samples from university and the general public. There was strong consensus that the Treaty of Waitangi was the most important event in New Zealand's history, but only Maori, the subordinate ethnic group, showed in‐group favouritism in their judgments regarding the Treaty. Pakeha, the dominant group, showed outgroup favouritism, and distanced themselves from past injustices using linguistic strategies. Maori students showed interest in their ethnic origins (ontogeny), rating the distant past and Polynesian history higher, and free‐recalling more events prior to European arrival than other groups; Maori in the general population shared a more similar perception of history to Pakeha. Both in‐group favouritism and ontogeny were found in sentence‐completion choices. Historical perceptions were strongly related to positions on current political issues. Results are related to social identity theory, social representations theory, and social dominance theory. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献
