When they are tested nonverbally, even young children demonstrate long-term recall. There have been few studies of whether early memories later are verbally accessible; the results of those that exist are mixed. Inconsistencies may be due to differences in the contextual cues provided at the time of recall. In two experiments, children 13–20 months were exposed to multi-step sequences and tested for nonverbal recall after 3–6 months. At age 3 years, they were tested verbally, under varying conditions of contextual support: in the original laboratory with event-related props versus at home with photographs of the props (Experiment 1), and at home with props (Experiment 2). Children younger than 20 months at initial experience of the events did not demonstrate verbal recall. Children who were 20 months at the initial exposure recalled verbally, as long as they had physical props as cues, regardless of whether testing took place at home or in the laboratory. This research informs the conditions under which memories from very early childhood later can be recalled verbally. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

The aim of this paper is to investigate the impact of 'negative behaviours' and 'bullying' in the workplace on the health and well-being of employees, to what extent the effects remain beyond the period of the experience as well as the extent to which they affect third-parties or witnesses. The paper also raises the question whether some behaviours associated with bullying may be more damaging than others. Potential sex differences and differences between occupational contexts are considered. To achieve these aims, a national cross-sectional study (N=5,388) was carried out. In absolute terms those who labelled their experience as bullying had substantially worse health than those who were not bullied. However, counter to what was expected, stronger associations were found between negative behaviour and adverse health effects than for self-reported (self-labelled) bullying and health. Previous targets as well as witnesses also reported worse health than those who were neither bullied nor had witnessed bullying. The findings also imply that some negative behaviours were more difficult to deal with than others. In all cases differences between the sexes and between occupational contexts emerged.  相似文献

This study explores some epidemiological features of bullying in Great Britain by means of a large-scale, nationwide survey, focusing on the differences in experience with regard to organizational status. Few differences were found for the experience of self-reported bullying between workers, supervisors, middle, or senior managers. The prevalence of bullying, duration of experience, status of perpetrator, whether the experience was shared with others or not, were similar across these organizational status groups. However, different factors may account for the experience of self-reported bullying for each of the organizational status groups. More discrepancies emerged when the behavioural experience of bullying was compared across groups. Workers and supervisors were more frequently exposed to negative acts than managers. They were also more likely to have been exposed to derogatory or exclusionary behaviour, whereas managers more frequently reported exposure to extreme work pressure. Moreover, when the results were adjusted for the possible impact of gender, a number of discrepancies between the organizational status groups emerged. The interaction between status and gender was explained by reference to cultural differences between men and women, the phenomenon of the ''glass-ceiling'' and the interaction between such factors and the prevailing socio-economic situation.  相似文献

In the United Kingdom, police officers do not, as a matter of routine, carry firearms. There are occasions, nevertheless, when armed police are deployed, and for obvious reasons any procedure that might improve the suitability of officers chosen to carry firearms is worth investigating.  相似文献
