Four- to 10-year-old children (n = 50) participated in a 2D search task that included geometry (with- and without lines) and feature conditions. During each of 27 trials, participants watched as a cartoon character hid behind one of three landmarks arranged in a triangle on a computer screen. During feature condition trials, participants could use the unique features of landmarks to locate the hidden character. During geometry condition trials the landmarks were identical, and participants had to rely on the geometric properties of the triangle they formed to locate the hidden character. In the feature condition, search accuracy was high for children of all ages. In the geometry condition (both with- and without lines), there was a sharp developmental trend in which 4-year-olds showed poor search accuracy, but performance improved with age and was at ceiling by 9- to 10-years. The presence of lines connecting the landmarks boosted performance most dramatically for the youngest children. Findings are discussed in the context of the broader literature on spatial cognition in human and non-human animals. 相似文献

Current knowledge of suicidal behavior in the Western Pacific region is relatively limited when compared to other areas of the world. This area is characterized by a wide diversity of social, economic, and cultural aspects that do not permit any homogenous reading of suicide phenomena. Data from countries of the region included in this article suggest the existence of important differences among nations in terms of gender, age, and methods of suicide, as well role of mental illness. In addition, the Western Pacific region appears to be affected by higher rates of suicide than other areas in the world, with signs of progressive worsening in recent years and worrying predictions for the next two decades. The Suicide Trends in At‐Risk Territories (START) Study, initiated by the World Health Organization Regional Office in Manila, seeks to research the incidence of both fatal and nonfatal suicidal behavior in countries of the region and to implement interventions for suicide attempters. This ambitious project is expected to standardize data collection procedures and improve the knowledge cultural factors in suicide. 相似文献

Three hundred fifty‐three women (median age = 32 years) admitted to the emergency rooms of nine general hospitals serving rural areas in China were interviewed for nonfatal suicidal behavior. Spousal conflict was the most commonly reported cause for their suicidal behavior and one third of respondents reported being victims of physical abuse by their spouses. Compared to non‐abused women, abused women were younger, had more disturbed family relationships, and experienced less financial hardship and more divorce. No differences were found between the groups in the proportion who reported psychiatric symptoms or in the level of suicidal intent; however, abused women were less impulsive and expressed more sadness at not having been successful in ending their lives. 相似文献

A representative sample of 10,233 adolescent students was recruited to examine the rate of suicidal attempt and its correlates in the adolescents living in southern Taiwan. Five questions from the Kiddie Schedule for Affective Disorders and Schizophrenia (Kiddie‐SADS‐E) were used to inquire about the participants' suicidality. The associations between suicidal attempt and multidimensional factors were examined by using logistic regression analysis: 9.1% of the participants reported a suicidal attempt in the preceding year. Female gender, low self‐esteem, weekly alcohol use, illicit drugs use, depression, high family conflict, low maternal education level, poor family function, low connectedness to school, low rank, poor feeling in peer group, and drop out from school were associated with adolescent suicidal attempt. The rate of suicidal attempt was found to be high in Taiwanese adolescents, and multidimensional factors were correlated to adolescent suicidal attempt. 相似文献

A community survey in 4,426 adults was undertaken as part of the World Mental Health Survey Initiative reporting the prevalence and risk factors for suicide‐related outcomes in Colombia. Lifetime prevalence estimates of suicide ideation, plans, attempts, and risk factors for suicide‐related outcomes were assessed. Retrospective reports of disorders age‐of‐onset were used to study associations between primary mental disorders and first onset of suicide‐related outcomes. Risks of plans and attempts were highest with ideation early age‐of‐onset and within the first year. The highest risk for ideation and attempt among ideators occurred in the 18–29 age group. After first employment (defined as the first paid job accepted by the respondent) and presence of mental disorders constituted risk factors. Impulse‐control disorders were strongest diagnostic predictors. 相似文献

The aim of the study was to ascertain suicide seasonality in the Greek population and to associate this seasonal variation with age, sex, and suicide method. Studying seasonality can be of help in establishing a public health policy, related with suicide prevention. This is an epidemiologic study based on forensic evidence. We studied the deaths caused by self‐injury (trauma), namely deaths by violent suicide (not self‐poisoning). Statistically significant suicide seasonality was established with a peak in May. This seasonal variation is attributed mainly to males. As for the method, suicide by hanging peaks in June and by shooting in April. It was also observed that seasonality for individuals above the age of 45 peaks in early May. 相似文献

Based on Durkheim's ‘Control theory,’ we explored the association between frequency of terror attacks in Israel and the frequency of suicide attempts admitted to the Emergency Room of a major general hospital in Tel‐Aviv (1999–2004). Analysis of the six‐year study period as a whole revealed no significant correlation between the variables, with the exception of one 11‐month segment within it (December 2000–October 2001) that did show a statistically significant positive correlation, and in opposition to Durkeim's hypothesis. It is suggested that suicide attempts as a phenomena should be seen as a product of a multivariate model, in which the social context plays a role as well. 相似文献

Suicide is an understudied subject in Pakistan. There are many social, legal, and religious sanctions against it. National rates of suicides are not known. We calculated suicide rates of women in the Ghizer District of the remote Northern Areas of Pakistan. During years 2000 to 2004, 49 women committed suicide. Taking average mean population for women for 5 years as 65,783, we calculated annual crude suicide rates for women as 14.89/100,000/year. For women over the age of 15 years, rates were 33.22/100,000/year; age‐specific rates for 15–24 years were 61.07/100,000 per year. These figures are considerably higher than suicide rates in other parts of Pakistan and may be related to high psychiatric morbidity in Pakistani women. This study underscores the need for a standardized system of registration of suicides in Pakistan. There is also urgent need to address high psychological distress in women in Pakistan. 相似文献

We investigated the psychometric validity and reliability of the Suicide Status Form‐II (SSF‐II) developed by Jobes, Jacoby, Cimbolic, and Hustead (1997) . Participants were 149 psychiatric inpatients (108 suicidal; 41 nonsuicidal) at the Mayo Clinic. Each participant completed assessment measures within 24 hours of admission and 48–72 hours later. Factor analyses of the SSF core assessment produced a robust two‐factor solution reflecting chronic and acute response styles. The SSF core assessment had good to excellent convergent and criterion validity; pre‐post SSF ratings also demonstrated moderate test‐retest reliability. The results replicated previous research and show that the SSF‐II is psychometrically sound with a high‐risk suicidal inpatient sample. 相似文献
