Research on the color-shading response on the Rorschach has been limited previously to its use as a predictor of suicide. The theoretical understanding of this response was addressed by some of the major Rorschach authors. Adult cystic fibrosis patients were administered a battery of psychological tests, including the Rorschach. While these patients face a premature death, none of these patients were suicidal. A higher than usual incidence of color-shading responses occurred. Rapaport's hypothesis that the color-shading response is an expression of a simultaneously conflicting emotion, or similar to "sweet sorrow," was suggested as a possible hypothesis. 相似文献

We test the hypothesis that COVID-19 vaccine hesitancy is attributable to distrustful complacency—an interactive combination of low concern and low trust. Across two studies, 9,695 respondents from different parts of Britain reported their level of concern about COVID-19, trust in the UK government, and intention to accept or refuse the vaccine. Multilevel regression analysis, controlling for geographic area and relevant demographics, confirmed the predicted interactive effect of concern and trust. Across studies, respondents with both low trust and low concern were 10%–22% more vaccine hesitant than respondents with either high trust or high concern, and 26%–29% more hesitant than respondents with both high trust and high concern. Results hold equally among White, Black, and Muslim respondents, consistent with the view that regardless of mean-level differences, a common process underlies vaccine hesitancy, underlining the importance of tackling distrustful complacency both generally and specifically among unvaccinated individuals and populations. 相似文献

COVID-19 has altered adolescents' opportunities for developing and strengthening interpersonal skills and proficiencies. Using data from adolescents in Italy, the United States, and the United Kingdom, we examined the relation between internalizing symptoms assessed pre-pandemic or when pandemic-related restrictions were lifted (Time 1) and associated internalizing symptoms during a subsequent restrictive pandemic period (Time 2). Across all 3 countries, we found significant and consistent effect sizes in the relation between Time 1 and Time 2 internalizing symptoms. We further examined the direct and moderating impact of self-efficacy and contextual supports for adolescents' internalizing symptoms. Higher self-efficacy was associated with lower levels of internalizing symptoms at Time 2 in all 3 countries. Additionally, the relation between Time 1 and 2 internalizing symptoms was buffered by regulatory self-efficacy and peer support in Italy, but in the U.S., higher levels of general self-efficacy instead had an exacerbating effect on the relation between Times 1 and 2 internalizing symptoms. Results are discussed in the context of utilizing cross-national datasets to examine similarities in adolescent well-being over time and in the face of varying government responses to the pandemic. 相似文献

When a word perception task was studied under conditions of binocular rivalry, the meaningful one of two rivalling strings of letters was identified more often than the other. Differences in frequency of the trigrams in the Norwegian language had no effect. 相似文献

A study was designed to compare several variables of Manpower Development Training Act (MDTA) clients who dropped out of the program with those of clients who completed the program. A random sample of application cards was drawn for individuals enrolled in MDTA adult classes in Milwaukee, Wisconsin. Trainees who completed the program were more likely to be married, older, characterized by a more stable employment history prior to entering the program, and slightly more educated than were program dropouts. Clients who completed the program versus those who did not were not significantly different on the following variables: (1) sex; (2) counseling versus no counseling; (3) race; and (4) client reported physical disability. 相似文献

The usual superiority in frequency-of-occurrence judgments of younger vs. older subjects was hypothesized to result from greater strategic encoding of the materials conveying frequency information. A subject-paced, visual search task was designed to control nontarget word encoding. Relative frequency judgments for the nontarget word pairs were equally accurate for younger and older subjects, and performance of both groups was above chance. Results suggest that strategic cover-task encoding can induce age differences in incidental frequency processing. Consistent with a nonoptimal as opposed to an optimal view, automatic processes require only minimal capacity for above-chance performance, but additional strategic resources can increase performance. When such additional resources are used more by younger than by older subjects, the former are better in frequency performance. 相似文献
