Basic objects in natural categories 总被引:1,自引:0,他引:1
Eleanor Rosch Carolyn B Mervis Wayne D Gray David M Johnson Penny Boyes-Braem 《Cognitive psychology》1976,8(3):382-439
Categorizations which humans make of the concrete world are not arbitrary but highly determined. In taxonomies of concrete objects, there is one level of abstraction at which the most basic category cuts are made. Basic categories are those which carry the most information, possess the highest category cue validity, and are, thus, the most differentiated from one another. The four experiments of Part I define basic objects by demonstrating that in taxonomies of common concrete nouns in English based on class inclusion, basic objects are the most inclusive categories whose members: (a) possess significant numbers of attributes in common, (b) have motor programs which are similar to one another, (c) have similar shapes, and (d) can be identified from averaged shapes of members of the class. The eight experiments of Part II explore implications of the structure of categories. Basic objects are shown to be the most inclusive categories for which a concrete image of the category as a whole can be formed, to be the first categorizations made during perception of the environment, to be the earliest categories sorted and earliest named by children, and to be the categories most codable, most coded, and most necessary in language. 相似文献

David V. Keith MD. 《Contemporary Family Therapy》1987,9(1-2):11-22
Intuition is an important part of a mature clinician's work. Yet, it is a component of clinical work which is looked upon with suspicion, due in part to the Middle-Age's association between intuition and the work of witches. This paper describes a tenuous link between intuition, witches, and Carl Whitaker. Patterns for including intuition in family therapy are discussed. 相似文献

Children in second, fourth and sixth grades and college sophomores were compared on a visual search and scanning task under three experimental conditions. In Condition I, a single target letter was sought in a list of letters of low visual confusability. In Condition II, two target letters were sought but only one appeared in a given list. In Condition III, a single target letter was sought in a list of letters of high confusability. Search time decreased with age in all three tasks. Searching for two targets was no harder than searching for one. A highly confusable visual context increased search time at all age levels. 相似文献

Risk Factors of a Suicide Reattempt by Seasonality and the Method of a Previous Suicide Attempt: A Cohort Study in a Japanese Primary Care Hospital 下载免费PDF全文
Minoru Sawa MD PhD Hiraki Koishikawa MD Yoneatsu Osaki MD PhD 《Suicide & life-threatening behavior》2017,47(6):688-695
Suicide has a great impact on the individual whose life is lost and the bereaved family members. The risk of a suicide reattempt is particularly high during the first 12 months after a suicide attempt. In this cohort study, risk factors for a suicide reattempt were explored among 291 patients at suicide risk. Clinical and demographic data were collected from a Japanese primary care hospital. Past psychiatric history and multiple diagnoses were associated with suicide reattempts in both genders. Drug overdose, past psychiatric history, and the summer season were linked to suicide reattempts among males. Past psychiatric history and multiple diagnoses were linked to suicide reattempts among females. Appropriate assessment of past psychiatric history, season and method of suicide attempt, gender, and diagnosis may play a role in preventing suicide. 相似文献

A Cross‐National Comparison of Suicide Attempts,Drug Use,and Depressed Mood Among Dominican Youth 下载免费PDF全文
Juan B. Peña PhD LCSW Katherine E. Masyn PhD Lorna E. Thorpe PhD Stephanie M. Peña MSW Eric D. Caine MD 《Suicide & life-threatening behavior》2016,46(3):301-312
We compared suicide attempts, depressed mood, and drug use of 1,710 Dominican public high school students in New York City (NYC) and 9,573 in the Dominican Republic (DR) in 2009. Compared to DR Dominicans, NYC Dominicans were more likely to have reported lifetime marijuana use (27.6% vs. 1.5%), lifetime inhalant use (11.0% vs. 7.6%), lifetime other drug use (9.9% vs. 3.0%), depressed mood (31.3% vs. 27.2%), and suicide attempt (13.8% vs. 8.8%). The results of this study supported the hypothesis that substantial increases in illicit drug use, especially cocaine, heroin, ecstasy, and methamphetamines, among NYC Dominican youth account for their increased risk for suicide attempts compared to their DR Dominican counterparts. It also identified suicide attempts as a public health problem among NYC Dominicans, the largest NYC Latino immigrant population. 相似文献
