Children without formal education in addition and subtraction are able to perform multi-step operations over an approximate number of objects. Further, their performance improves when solving approximate (but not exact) addition and subtraction problems that allow for inversion as a shortcut (e.g., a?+?b???b?=?a). The current study examines children's ability to perform multi-step operations, and the potential for an inversion benefit, for the operations of approximate, non-symbolic multiplication and division. Children were trained to compute a multiplication and division scaling factor (*2 or /2, *4 or /4), and were then tested on problems that combined two of these factors in a way that either allowed for an inversion shortcut (e.g., 8*4/4) or did not (e.g., 8*4/2). Children's performance was significantly better than chance for all scaling factors during training, and they successfully computed the outcomes of the multi-step testing problems. They did not exhibit a performance benefit for problems with the a*b/b structure, suggesting that they did not draw upon inversion reasoning as a logical shortcut to help them solve the multi-step test problems. 相似文献

Although the development of number-line estimation ability is well documented, little is known of the processes underlying
successful estimators’ mappings of numerical information onto spatial representations during these tasks. We tracked adults’
eye movements during a number-line estimation task to investigate the processes underlying number-to-space translation, with
three main results. First, eye movements were strongly related to the target number’s location, and early processing measures
directly predicted later estimation performance. Second, fixations and estimates were influenced by the size of the first
number presented, indicating that adults calibrate their estimates online. Third, adults’ number-line estimates demonstrated
patterns of error consistent with the predictions of psychophysical models of proportion estimation, and eye movement data
predicted the specific error patterns we observed. These results support proportion-based accounts of number-line estimation
and suggest that adults’ translation of numerical information into spatial representations is a rapid, online process. 相似文献

Adults vary their haptic exploratory behavior reliably with variation both in the sensory input and in the task goals. Little is known about the development of these connections between perceptual goals and exploratory behaviors. A total of 36 children ages 3, 4, and 5 years and 20 adults completed a haptic intramodal match-to-sample task. Participants were instructed to feel the shape, texture, rigidity, or weight of a sample object and then were asked to find which of three test objects matched the sample on that specific property. Hand movements were examined to determine whether children produced the same exploratory procedures while gathering perceptual information about each property as adults who searched for the same kind of information. Children demonstrated that they had good haptic abilities in two ways: They matched the sample objects on the specified perceptual dimension at near ceiling levels, and they produced the same hand movement patterns to find the same properties as adults. 相似文献

Transcendence Matters: Do the Ways Family Members Experience God Meaningfully Relate to Family Life?
As more Americans continue to move away from an institutional approach to religion and spirituality to a more personal approach, it is important to explore the ways that personal perspectives about God influence various aspects of life including family life. This study explored how participants viewed and experienced God as an authority figure (Directive Transcendence), as a close confidant (Intimate Transcendence), or as both (Authoritative Transcendence). In-depth interviews with 198 religious families from across America were analyzed using a team-based qualitative approach. These analyses revealed that participants experienced God as both an authority figure and as a close confidant. Both types of experiences are associated with family relationships in different ways. Concepts relating to ideas of authority, parenting styles, and attachment theory are used to help understand familial impacts from how one experiences God. 相似文献

Body dysmorphic disorder is associated with elevated social and occupational impairment and comorbid depression, but research on risk factors for body dysmorphic symptoms and associated outcomes is limited. Appearance-based teasing may be a potential risk factor. To examine the specificity of this factor, the authors assessed self-reported appearance-based teasing, body dysmorphic, and obsessive-compulsive symptom severity, functional impairment (i.e., social, occupational, family impairment), and depression in a nonclinical sample of undergraduates. As hypothesized, appearance-based teasing was positively correlated with body dysmorphic symptoms. The correlation between teasing and body dysmorphic symptoms was stronger than that between teasing and obsessive-compulsive symptom severity. Last, body dysmorphic symptom severity and appearance-based teasing interacted in predicting functional impairment and depression. Specifically, appearance-based teasing was positively associated with depression and functional impairment only in those with elevated body dysmorphic symptoms. When a similar moderation was tested with obsessive-compulsive, in place of body dysmorphic, symptom severity, the interaction was nonsignificant. Findings support theory that appearance-based teasing is a specific risk factor for body dysmorphic symptoms and associated functional impairment. 相似文献
