A basic phenomenon of cognitive arithmetic is that problems composed of a repeated operand, so-called "ties" (e.g. 6+6, 7 x 7), typically are solved more quickly and accurately than comparable non-tie problems (e.g. 6+5, 7 x 8). In Experiment 1, we present evidence that the tie effect is due to more efficient memory for ties than for non-ties, which participants reported solving more often using calculation strategies. The memory/strategy hypothesis accounts for differences in the tie effect as a function of culture (Asian Chinese vs. non-Asian Canadian university students), operation (addition, multiplication, subtraction, and division), and problem size (numerically small vs. large problems). Nonetheless, Blankenberger (Cognition 82 (2001) B15) eliminated the tie response time (RT) advantage by presenting problems in mixed formats (e.g. 4 x four), which suggests that the tie effect with homogenous formats (4 x 4 or four x four) is due to encoding. In Experiment 2, using simple multiplication problems, we replicated elimination of the tie effect with mixed formats, but also demonstrated an interference effect for mixed-format ties that slowed RTs and increased errors relative to non-tie problems. Additionally, practicing non-tie problems in both orders (e.g. 3 x 4 and 4 x 3) each time ties were tested once (cf. Cognition 82 (2001) B15) reduced the tie effect. The format-mismatch effect on ties, combined with a reduced tie advantage because of extra practice of non-ties, eliminated the tie effect. Rather than an encoding advantage, the results indicate that memory access for ties was better than for non-ties. 相似文献

Two studies tested whether method variance is present at multiple levels of analysis and whether methodological procedures can minimize its impact. In Study 1, 8,052 employees from 71 hotels completed measures of climate, work environment characteristics, and satisfaction. A comparison of correlations at the individual level, cross-level, cross-level split, aggregate level, and aggregate-split level of analysis revealed that response bias was present across multiple levels. Results suggest that samples should be split in half when cross-level and aggregate correlations are computed to ameliorate response bias problems that arise from individual-level method variance. In Study 2, results indicated that the temporal spacing of measures of climate and satisfaction influenced response bias. Implications and recommendations for future research are discussed. 相似文献

Simple addition (e.g., 3 + 2, 7 + 9) may be performed by direct memory retrieval or by such procedures as counting or transformation. The distribution of associations (DOA) model of strategy choice (Siegler, 1988) predicts that procedure use should increase as retrieval interference increases. To test this, 100 undergraduates performed simple addition problems, either after blocks of simple multiplication (high-interference context) or after blocks of simple division problems (low-interference context). Addition took longer and was more error prone after multiplication; in particular, there were more multiplication confusion errors on the relatively easy, small-number addition problems (e.g., 3 + 2 = 6, 4 + 3 = 12), but not on the more difficult, large-number additions. Consistent with the DOA, participants reported greater use of procedures for addition after multiplication, but more so for small addition problems. The findings demonstrate that adults’ use of procedural strategies for simple addition is substantially influenced by retrieval interference. 相似文献

Caregiver social support has been shown to be protective for caregiver mental health, parenting and child psychosocial outcomes. This is the first known analysis to quantitatively investigate the relationship between caregiver social support and adolescent psychosocial outcomes in HIV‐endemic, resource–scarce Southern African communities. A cross‐sectional household survey was conducted over 2009–2010 with 2,477 South African adolescents aged 10–17 and their adult caregivers (18 years or older) in one urban and one rural community in South Africa’s KwaZulu‐Natal province. Adolescent adjustment was assessed using adult caregiver reports of the Strengths and Difficulties questionnaire (SDQ), which measures peer problems, hyperactivity, conduct problems, emotional symptoms and child prosocial behavior. Hierarchical linear regressions and multiple mediation analyses, using bootstrapping procedures, were conducted to assess for: (a) direct effects of more caregiver social support on better adolescent psychosocial wellbeing; and (b) indirect effects mediated by better parenting and caregiver mental health. Direct associations (p < .001), and indirect associations mediated through better parenting, were found for all adolescent outcomes. Findings reinforce the importance of social support components within parenting interventions but also point to scope for positive intervention on adolescent psychosocial wellbeing through the broader family social network. 相似文献

The authors examined the role spirituality can play as a protective factor in the wellness of older adults residing in the Appalachian region of the United States. Analysis of participants' interviews identified 4 themes. These themes and implications for counselors working with Appalachian older adults are discussed. 相似文献

In this exploratory study of the relationship between characteristics of breathing and 3 common psychological issues (i.e., symptoms of anxiety, alexithymia, and depression), 79 college‐age adults were examined using self‐report, rater observation, and physiological measures. Results indicated significant positive relationships between dysfunctional breath characteristics and symptoms of both anxiety and alexithymia. A significant positive correlation was found between self‐reported symptoms of dysfunctional breathing and symptoms of depression, but no significant relationships existed between symptoms of depression and either rater‐observed breath characteristics or physiological measures. 相似文献

This study explores: (1) how criminal family networks facilitate cost avoidance strategies by urban drug sellers and (2) transmission of criminal capital by these networks. Twenty interviews with drug sellers in Philadelphia found that family networks provided unique access to cost avoidance techniques that appeared to reduce offenders’ risk of arrest and violent victimization. Transfer of family criminal capital was not limited to mentoring and tutelage; these networks also allowed sellers to access the organizational structure at higher levels, inherit existing businesses, and make errors with few consequences. Extant theory could be advanced by considering social sources of criminal capital. 相似文献

Across 6 studies, relationship closeness strongly influenced moral attribution. First, we found that moral attributions were stronger when one interacted with an intimate compared to less intimate other. Second, we examined attributions about those who treat some people well and others badly. Moral character attributions were worse when an actor harmed an intimate relationship partner compared to a less close relationship partner. Further, the effect of relationship partner on moral attributions was influenced by perceivers’ beliefs about one’s true character. Perceivers were apt to believe that one’s true character is revealed when interacting with close others. 相似文献
