This paper offers an explanation of how collaboration leads to abstract and flexible problem solving. We asked the individual and paired subjects to indicate 3/4 of 2/3 of the area of a square sheet of paper and found that (1) they primarily folded or partitioned the paper rather than algorithmically calculating the answer, (2) they strongly tendened to backtrack and confirm their proto‐plans on externalized traces such as creases on the paper, and (3) only the paired subjects shifted to the mathematical strategy in their second trials. Based on these results, we propose that two factors, individuals' activeness in choosing and confirming the initial strategies and the frequent role exchange between task‐doing and monitoring in collaborative situations, interact in collaboration to generate various solutions differing in the degree of abstraction, which are then reflected upon by the participants to lead them to abstraction. 相似文献
This study examines whether public opinion parallels recent judicial and statutory changes limiting the applicability of capital sentences to offenders younger than 18 years old. Two hundred and thirty-five undergraduate students were administered a vignette of a capital case and asked to render a sentence of death or life in prison without parole. Results revealed that age of the defendant was not a significant predictor of sentence type; participants sentenced 16- and 17-year-old defendants similarly to 18- and 25-year-old defendants. Therefore, public opinion appears inconsistent with legal and legislative changes to abandon the practice of executing juveniles. Findings also suggested that perceived level of the defendant's responsibility and general opinion about capital sentences significantly predicted sentence type; perceptions of greater responsibility were associated with an increased likelihood of a death sentence. However, participants did not perceive differences in responsibility between juvenile and adult defendants. In addition, participants were more comfortable sentencing defendants to death compared with life in prison. 相似文献
Many organizations have diversity statements in place in which they publicly declare their appreciation of and commitment to workforce diversity. These statements can either contain moral motives (e.g., “diversity reduces social inequalities”), business motives (e.g., “diversity enhances innovation”), or a combination of moral and business motives. In a desk study involving 182 Dutch organizations, we found that (a) private sector organizations more often than public sector organizations communicate business motives, (b) that public and private sector organizations are equally likely to communicate moral motives, and (c) that public sector organizations more frequently than private sector organizations communicate a combination of moral and business motives. Next, we used an experimental design to examine the causal influence of communicating different diversity motives on organizations' employment image (i.e., perceptions of organizational morality, competence, and attractiveness) among prospective employees (n = 393). Here, we used a scenario in which a healthcare organization was portrayed as either a public or a private sector organization and communicated either only moral motives, only business motives or a combination of moral and business motives for diversity. We found that for a public sector organization communicating moral instead of business motives for valuing diversity induced a more favorable employment image. For a private sector organization, there were no differences in employment image depending on the motive communicated. Together, these two studies shed new light on the role of diversity motives in establishing a positive employment image. 相似文献
The role of vision and vision deprivation in the development of executive function (EF) abilities in childhood is little understood; aspects of EF such as initiative, attention orienting, inhibition, planning and performance monitoring are often measured through visual tasks. Studying the development and integrity of EF abilities in children with congenital visual impairment (VI) may provide important insights into the development of EF and also its possible relationship with vision and non-visual senses. The current study investigates non-visual EF abilities in 18 school-age children of average verbal intelligence with VI of differing levels of severity arising from congenital disorders affecting the eye, retina, or anterior optic nerve. Standard auditory neuropsychological assessments of sustained and divided attention, phonemic, semantic and switching verbal fluency, verbal working memory, and ratings of everyday executive abilities by parents were undertaken. Executive skills were compared to age-matched typically-sighted (TS) typically-developing children and across levels of vision (mild to moderate VI [MVI] or severe to profound VI [SPVI]). The results do not indicate significant differences or deficits on direct assessments of verbal and auditory EF between the groups. However, parent ratings suggest difficulties with everyday executive abilities, with the greatest difficulties in those with SPVI. The findings are discussed as possibly reflecting increased demands of behavioral executive skills for children with VI in everyday situations despite auditory and verbal EF abilities in the typical range for their age. These findings have potential implications for clinical and educational practices. 相似文献
Objective: The prevailing focus regarding eating behaviour is on restriction, concern, worry and pathology. In contrast, the purpose of the present studies was to focus on a positive relationship with eating in non-clinical samples from Germany, the USA and India.
Design: In Study 1, the Positive Eating Scale (PES) was tested and validated in a large longitudinal sample (T1: N = 772; T2: N = 510). In Study 2, the PES was tested in online samples from the USA, India and Germany (total N = 749).
Main Outcome Measures: Health risk status was measured in Study 1 with objective health parameters (fasting serum glucose, triglycerides, high-density lipoprotein cholesterol, blood pressure, waist circumference, BMI).
Results: Study 1 revealed acceptable psychometric properties of the PES, internal consistency (α = .87), as well as test–retest reliability after six months (r = .67). Importantly, a positive relationship with eating was associated with decreased health risk factors six months later. In Study 2, the structure of the PES was confirmed for German, Indian and US-American adults, suggesting validity across remarkably different eating environments.
Conclusion: A positive relationship with eating might be a fruitful starting point for prevention and intervention programmes promoting physical and psychological health. 相似文献
