The constancy of a 16-step achromatic Munsell scale was tested with regards to background variations in two experiments. In
experiment 1 three groups of observers were asked to find lightness matches for targets in simultaneous lightness displays
by using a 16-step achromatic Munsell scale placed on a white, black, or white-black checkered background. In experiment 2,
a yellow-blue checkered background and a green-red checkered background replaced Munsell scales on the black and on the white
backgrounds. Significant effects of scale background on matches were found only in experiment 1, suggesting that background
luminance is a crucial factor in the overall appearance of the scale. The lack of significant differences in experiment 2,
however, may stand for an overall robustness of the scale with respect to background luminance changes occurring within certain
luminance ranges. 相似文献

Patients with bipolar disorder (BD) and schizophrenia (SZ) often show decision-making deficits in everyday circumstances. A failure to appropriately weigh immediate versus future consequences of choices may contribute to these deficits. We used the delay discounting task in individuals with BD or SZ to investigate their temporal decision making. Twenty-two individuals with BD, 21 individuals with SZ, and 30 healthy individuals completed the delay discounting task along with neuropsychological measures of working memory and cognitive function. Both BD and SZ groups discounted delayed rewards more steeply than did the healthy group even after controlling for current substance use, age, gender, and employment. Hierarchical multiple regression analyses showed that discounting rate was associated with both diagnostic group and working memory or intelligence scores. In each group, working memory or intelligence scores negatively correlated with discounting rate. The results suggest that (a) both BD and SZ groups value smaller, immediate rewards more than larger, delayed rewards compared with the healthy group and (b) working memory or intelligence is related to temporal decision making in individuals with BD or SZ as well as in healthy individuals. 相似文献

Objective: To evaluate whether the mother–child interactions of hyperactive preschool children and their typically developing peers differentially vary as a function of situational demands, and whether groupwise differences exist with respect to disciplinary practices and family lifestyles (e.g. level of parental investment, strategies for responding to child‐initiated provocation). Methods: Parenting practices were assessed via videotaped parent–child interactions and self‐report methods in mother–child dyads of 21 hyperactive preschoolers and 48 age‐matched control dyads. Results: Hyperactive preschoolers were significantly more non‐compliant during parent–child interactions. Mothers of hyperactive preschoolers exhibited more negative behaviour and less encouragement with heightened situational demands. Although few significant differences were reported regarding disciplinary practices, parents of hyperactive preschoolers reported greater levels of anger and child rearing difficulty, and perceived their children as more bothersome. Conclusions: Parents of hyperactive preschoolers may profit from interventions that are sensitive to the impact of situational changes on their behaviour and which address possible attributional biases regarding the source of parent–child discord.

Confident business forecasters are seen as more credible and competent (“confidence heuristic”). We explored a boundary condition of this effect by examining how individuals react to the trade‐off between confidence and optimism. Using hypothetical scenarios, we examined this trade‐off from the perspectives of judges (i.e., business owners who hired analysts to make sales predictions) and forecasters (i.e., the analysts hired to make predictions). Participants were assigned to the role of either judges or forecasters and were asked to rate 2 potential forecasts. In the “no trade‐off” condition, the 2 forecasts were aligned in optimism and confidence (the more confident forecast was also more optimistic); in the “trade‐off” condition, the more confident forecast was less optimistic. In Experiment 1, judges were more likely to positively evaluate confident forecasters when confident forecasters were the more (vs. less) optimistic ones. Experiment 2 demonstrated that forecasters were aware of judges' preferences for optimism and strategically relied on methods that resulted in more optimistic (but less reliable) predictions. Experiment 3 directly compared the perspectives of judges and forecasters, revealing that forecasters overestimated judges' preferences for optimism over confidence. The present studies show that forecasters and judges have different views of the trade‐off between confidence and optimism and that forecasters may unnecessarily sacrifice accuracy for optimism. 相似文献

Background/ObjectivesAccording to existing evidence, parental educational practices and social anxiety are to some degree connected. However, the possibility that this relationship is an indirect one and is mediated by individual factors such as self-esteem or emotional regulation has not yet been explored. The aim of this study was therefore to explore the relationship between maternal and paternal educational practices and social anxiety, and test both the direct and the indirect pathways. Method: The representative sample consisted of 2,060 Andalusian students (47.7% girls, Mage = 14.34) who filled in various self-reports. Results: The structural equation models confirmed that a direct relationship, with a low effect size, exists between parental educational practices and social anxiety and that there is also an indirect relationship, mediated by negative self-esteem and emotional suppression (the emotional regulation strategy), which accounted here for 49.1% of the variance in social anxiety. Conclusions: Parental education practices seem to act as a family asset which either promotes or hinders the development of basic attitudes and competencies such as self-esteem or emotional regulation and, by doing this, either encourages or prevents the emergence of problems such as social anxiety. 相似文献

This paper makes use of certain thought-provoking ideas from Lacan's seminars in the years between 1959 and 1962 in order to engage with the very subtly conveyed inner drama that subtends the plot of Ian McEwan's novel Enduring Love . Freud, in his 1914 paper 'On narcissism', had referred to theories on the earliest moments of subjectivity as 'nebulous, scarcely imagined concepts'. In 1959 Lacan created a concept that he called the o-object to make incursions into theories on the lasting impact of the anxiety-ridden passage of the small pre-subject into subjective existence. In particular, the seminar on Anxiety (1962-3), for all the convolutions of syntax and sense that render it so difficult to read, opens up reflections on this topic that are not dissimilar to those stimulated by McEwan's accomplished prose. Both Lacan and McEwan explore the problematic dissolution of the everyday distinction between subjectivity and objectivity attendant on the upsurge of anxiety driven by unconscious forces. 相似文献

Let's Ask the Homeless People Themselves: A Needs Assessment Based on a Probability Sample of Adults
A probability sample of 301 homeless adults from Buffalo, NY, was followed over 6 months to document the utilization of a variety of community services, examine services desired, and identify factors associated with service utilization, preference, and satisfaction. The following needs were all rated as at least equally important as the need for affordable housing: safety, education, transportation, medical/dental treatment, and job training/placement (most of these needs were also rated as difficult to obtain). Needs for formal mental health and substance abuse services were rated as relatively unimportant and easy to obtain, and for those who actually used them, respondents were often dissatisfied with them. Of 16 predictor variables examined in multivariate analyses, several showed consistent relationships with subsequent service use, preference, and satisfaction. Younger adults, persons of color, those with dependent children, and persons having fewer social supports reported less service utilization, less satisfaction with services received, different perceived needs for particular services, and/or greater difficulty obtaining services. 相似文献

In analyzing the relation between job satisfaction and job security, a sample of 97 Greek fitness instructors, 18 to 42 years of age, showed statistically significant positive correlations between job security and job satisfaction (p<.002). Particularly, job security was correlated with pay .54, promotion .43, job itself .41, and the organization as a whole .43. 相似文献
