This study examined violence and aggression in five agencies providing day services in homelessness or mental health. Incident reporting was used to test the hypotheses that aggression is associated with alcohol problems, drug use, mental disorder, homelessness, history of violence, age and sex. Agency policies and patterns to aggressive incidents were explored. Three agencies provided a sufficient number of incidents for analysis (involving 30 ‘aggressors’). A history of violence was associated with aggression in all three agencies; alcohol problems, drug use and younger age were associated with aggression in at least one agency; no association was found for mental disorder, homelessness or sex. A degree of pattern to incidents could be discerned, with drink or drugs often involved, and exercises of authority or intervention in client altercations being particularly likely to precede aggression towards staff. A variety of incidents were reported, from verbal arguments to threats with a knife and serious physical assault. © 1997 John Wiley & Sons, Ltd.  相似文献

A temporal ratio model of memory   总被引:1,自引:0,他引:1  
A model of memory retrieval is described. The model embodies 4 main claims: (a) temporal memory--traces of items are represented in memory partly in terms of their temporal distance from the present; (b) scale-similarity--similar mechanisms govern retrieval from memory over many different timescales; (c) local distinctiveness--performance on a range of memory tasks is determined by interference from near psychological neighbors; and (d) interference-based forgetting--all memory loss is due to interference and not trace decay. The model is applied to data on free recall and serial recall. The account emphasizes qualitative similarity in the retrieval principles involved in memory performance at all timescales, contrary to models that emphasize distinctions between short-term and long-term memory.  相似文献

This article examines the contemporary growth of pilgrimages. Examples are provided from variety of traditions and parts of the world, from Japan to Europe, with particular attention paid to the Shikoku and Santiago de Compostela pilgrimages that have experienced extensive growth in recent years. It also draws attention to the growing number of new pilgrimage sites that are not associated with any specific religious traditions or that have ‘New Age’ associations. While some of the factors accounting for this growth involve continuities from past eras, there are also specifically modern factors. Also considered in this article is how some modern pilgrims appear to repudiate organised religion even while visiting sites normally associated with established religious traditions. Rather than implying some form of religious revival, contemporary pilgrimage growth may, then, be seen as evidence of an increasing turn away from religion as an organised entity.  相似文献

The aim of the research was to assess the views of young people about school counselling. In total, 415 pupils from five secondary schools took part in the survey. A smaller number of these pupils took part in focus groups (n=9) to explore their views in more depth. In general, the young people seemed to value having a school counsellor. Most were aware of the school counselling service, although a substantial number (21%) indicated a lack of awareness. For many who were aware, their knowledge of the service was limited. Just over one third of the pupils stated that they would go to see the school counsellor, and girls were more likely to state this than boys. The confidentiality of the service was perceived to be one of the benefits. However, this was also reported to be a hindering factor—the concern that it may not, in fact, be confidential. Two other main reasons for not accessing the service were the counsellor being a stranger and (for boys in particular) a concern about other people finding out (associated with the social stigma of going for counselling). Suggestions to improve the school counselling service included a room in a discrete location, better promotion of the service, more counsellors or a full-time counsellor, and ways to get to know the counsellor better. Those responsible for developing and managing school counselling services should consider these suggestions.  相似文献

Lexical compounds in English are constrained in that the non-head noun can be an irregular but not a regular plural (e.g. mice eater vs. *rats eater), a contrast that has been argued to derive from a morphological constraint on modifiers inside compounds. In addition, bare nouns are preferred over plural forms inside compounds (e.g. mouse eater vs. mice eater), a contrast that has been ascribed to the semantics of compounds. Measuring eye-movements during reading, this study examined how morphological and semantic information become available over time during the processing of a compound. We found that the morphological constraint affected both early and late eye-movement measures, whereas the semantic constraint for singular non-heads only affected late measures of processing. These results indicate that morphological information becomes available earlier than semantic information during the processing of compounds.  相似文献

In the present experiment, we used a reversed-contingency paradigm (the windows task: [Russell, J., Mauthner, N., Sharpe, S., & Tidswell, T. (1991). The windows task as a measure of strategic deception in preschoolers and autistic subjects. British Journal of Developmental Psychology, 9, 331-349]) to explore the effect of alterations in the task array on 3-year-old children's strategic reasoning. Children were offered a choice between either a desirable object and an undesirable object, or between a desirable object and an empty location. There was significantly better performance on the two-object version of the task. This difference was evident even on subsequent trials when the second object was removed and the empty location reintroduced. This suggests that presenting children with a choice between two objects helps them to formulate a strategy, rather than to execute a previously determined response.  相似文献

The weights of 5 pigeons with free access to food, monitored over 3 calendar years in the laboratory, were found to fluctuate with season. All pigeons were at their heaviest in the winter and were lightest in the summer. Five different pigeons performed a standard delayed matching-to-sample task for 44 weeks from January to November. Their weights were held at 85% of their summer free-feeding weights, making their predicted deprivation level higher in the winter relative to predicted winter free-feeding weights. Slopes of forgetting functions fit to weekly response totals for each pigeon were shallower in winter, showing an improvement in accuracy with longer delays. Thus, delayed matching-to-sample performance may have been affected by the practice of maintaining the pigeons at a constant body weight throughout the calendar year.  相似文献

Males with fragile X syndrome (FXS) have difficulties with social interaction and many show autistic features. This study examined whether the social deficits characteristic of FXS are associated with theory of mind difficulties. Two groups of boys with FXS participated: a group with few autistic features and a group with many autistic features. An intellectual disability control group also participated. In addition to using standard theory of mind tasks, new techniques were used that were able to separate out the various processing demands of the task (e.g., memory, inhibitory control). Overall, the findings indicate that both groups of boys with FXS have difficulty with theory of mind tasks compared to an intellectual disability control group. However, both groups with FXS also performed worse on comparison trials that required working memory but not theory of mind. Theory of mind difficulties are likely to be an important aspect of the FXS clinical profile, but are most likely the result from a more basic difficulty with working memory.  相似文献

Numerous studies have demonstrated impaired recall when the to-be-remembered information is accompanied or followed by irrelevant information. However, no current theory of immediate memory explains all three common methods of manipulating irrelevant information: requiring concurrent articulation, presenting irrelevant speech, and adding a stimulus suffix. Five experiments combined these manipulations to determine how they interact and which theoretical framework most accurately and completely accounts for the data. In Experiments 1 and 2, a list of auditory items was followed by an irrelevant speech sound (the suffix) while subjects engaged in articulatory suppression. Although articulatory suppression reduced overall recall compared to a control condition, comparable suffix effects were seen in both conditions. Experiments 3 and 4 found reliable suffix effects when list presentation was accompanied by irrelevant speech. Experiment 5 found a suffix effect even when the irrelevant speech was composed of a set of different items. Implications for working memory, pre-categorical acoustic store, the changing-state hypothesis, and the feature model are discussed.  相似文献
