Participants were trained and tested to select stimuli of differing physical quantities in the presence of 2 color contextual cues for more than and less than. Following more than and less than relational training, participants allocated the majority of their responses to the slot machine that shared formal properties of color with the contextual cue for more than, despite the identical payout probabilities of the slot machines.  相似文献

In this longitudinal study, we compared family stories told by 32 Canadian adolescents at ages 16 and 20 about how parents and grandparents had taught them values. Relations to parents' and children's levels of generativity were also examined. Adolescents' stories of grandparent value teaching were less readily recalled and less interactive in their content compared with stories about parents. Stories of value teaching by more generative parents were more likely to involve specific episodes, to be more interactive, to be more likely to emphasize caring content, and to be less likely to have their message rejected by the teens. Similarly, when parents were more generative, adolescents' stories about grandparents' value teaching were also more likely to involve specific and interactive episodes. Finally, stories told about parents and grandparents that were more positive on these dimensions predicted higher generative concern scores for the adolescents themselves, measured subsequently at age 24. Adolescents' stories about parent and grandparent socialization in more generative family contexts thus have features that suggest a more compelling process of intergenerational value transmission.  相似文献

The suggestion that maladaptive behaviour often observed in survival incidents may be due to a restriction in attentional processing was tested using sub‐components of the Test of Everyday Attention in participants undergoing a field survival exercise. Compared to a baseline condition and control group those undergoing environmental duress showed significant impairment in selective and sustained attention which taken together suggests dysfunction in controlled attention. No impairment was found in either attentional switching or auditory‐verbal working memory. It is argued that this type of cognitive impairment makes flexible interaction with the survival environment difficult and the victim's behaviour becomes dominated by environmental cues at the expense of wilful, goal‐directed survival behaviour. This would begin to answer at least one anomaly that exists in survivorship: why so many people perish when there is no need. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Finding direct and indirect influences of salient psychosocial and situational variables on problem substance use among homeless people is important in designing evidence-based, effective, and relevant interventions for this special population. A stress-coping paradigm in conjunction with situational items specialized for homeless people was used to explore predictive relationships in a sample of homeless adults (N = 664) among (a) psychosocial variables of self-esteem, social support, positive and negative coping, and emotional distress, (b) situational variables of homelessness history and quality of recent housing, and (c) outcomes of alcohol use, injection drug use (IDU), and non-IDU. Lower self-esteem predicted greater emotional distress, lower positive coping, greater negative coping, and more alcohol use. Social support predicted less emotional distress and more positive coping. Chronic homelessness predicted more emotional distress, less positive coping, greater alcohol use, and IDU. Poor housing was associated with more alcohol use and IDU. Substance abuse interventions among the homeless should have a dual focus that includes attention to psychological issues and negative coping patterns while also addressing situational, environmental factors, including encouraging provision of permanent supportive housing.  相似文献

In this study, the authors examined whether parent-child conflict during the middle childhood years varied among families characterized as having different cultural traditions regarding issues of respect for parental authority and parenting practices. The sample included 133 African American, European American, and Latina girls (M age = 8.41 years) and their mothers. African American and Latina girls showed significantly more respect for parental authority than did European American girls. Furthermore, African American and Latina mothers reported significantly more intense arguments when respect was low than did European American mothers. Higher levels of discipline and better communication by mothers were both associated with reports of lower frequency of conflict; ethnicity did not moderate this association. Thus, respect for authority was most salient to group differences in conflict.  相似文献

Overweight in youth is increasing and physical inactivity has been implicated as a causal factor. An after-school care intervention, Youth Fit For Life, has been associated with significant improvements in physiological factors and frequency of moderate-to-vigorous physical activity voluntarily completed outside of structured settings. Correlates of the observed changes in physical activity amounts were, however, unknown. A multiple regression equation with simultaneous entry of sex, age, race, initial Body Mass Index, and initial frequency of voluntary physical activity as predictor variables for changes in physical activity was calculated on Euro-American and African-American participants ages 8 to 12 years (N=217). A statistically significant 16% of the variance in changes in frequency of voluntary physical activity over 12 wk. was accounted for, with only voluntary physical activity at baseline and age making significant, unique contributions. For participants either overweight or at risk for overweight (n=72), the changes in physical activity significantly correlated with changes in Body Mass Index. Implications of findings to maximize treatment effects on voluntary physical activity were suggested.  相似文献

The authors review current literature on issues facing American Indian (AI) women and discuss implications for providing culturally sensitive counseling with these women. A case study of a Diné (Navajo) woman living within mainstream society and holding true to her traditional cultural beliefs illustrates how a culturally responsive approach to counseling AI women is integral for individual counseling with this population. Los autores revisan la literatura actual en asuntos afectando a mujeres Indias Americanas (AI) y discuten las implicaciones para proporcionar el aconsejar sensible culturalmente con estas mujeres. Un caso de una mujer Diné (navajo) que vive dentro de la sociedad convencional y mantiene válida a sus creencias culturales tradicionales que ilustra cómo un enfoque culturalmente receptivo a aconsejar mujeres Indias Americanas es integral para el aconsejo individual con esta población.  相似文献

In this paper I look at attempts to develop forms of consequentialism which do not have a feature considered problematic in Direct Consequentialist theories (that is, those consequentialist theories that apply the criterion of rightness directly in the evaluation of any set of options). The problematic feature in question (which I refer to as ‘evaluative conflict’) is the possibility that, for example, a right motive might lead an agent to perform a wrong act. Theories aiming to avoid this phenomenon must argue that causal relationship entails motives and acts (for example) having the same moral status. I argue that attempts to ensure such ‘evaluative consistency’ are themselves deeply problematic, and that we must therefore accept evaluative conflict.  相似文献

In a series of eight studies it is shown that the first peak in the horizontal autocorrelation of the image of a word (which captures the similarity in shape between the neighbouring strokes of letters) determines (i) the appearance of the words as striped; (ii) the speed with which the words are read, both aloud and silently; and (iii) the speed with which a paragraph of text can be searched. By subtly distorting the horizontal dimension of text, and thereby reducing the first peak in the horizontal autocorrelation, it is shown that the speed of word recognition can be increased. The increase in speed is greater in poor readers.  相似文献
