In this longitudinal population-based study (N?=?544), we investigated whether early parenting and corpus callosum length predict child executive function abilities at 4 years of age. The length of the corpus callosum in infancy was measured using postnatal cranial ultrasounds at 6 weeks of age. At 3 years, two aspects of parenting were observed: maternal sensitivity during a teaching task and maternal discipline style during a discipline task. Parents rated executive function problems at 4 years of age in five domains of inhibition, shifting, emotional control, working memory, and planning/organizing, using the Behavior Rating Inventory of Executive Function-Preschool Version. Maternal sensitivity predicted less executive function problems at preschool age. A significant interaction was found between corpus callosum length in infancy and maternal use of positive discipline to determine child inhibition problems: The association between a relatively shorter corpus callosum in infancy and child inhibition problems was reduced in children who experienced more positive discipline. Our results point to the buffering potential of positive parenting for children with biological vulnerability.  相似文献

记忆训练对改善少年、青年和老年人认知功能的作用   总被引:1,自引:1,他引:1  
本工作采用“位置法”(method of loci)对24例少年、24例青年和22例老年被试进行了记忆训练研究。以毕生发展的观点比较认知训练对改善不同年龄人记忆的作用,进而探讨发展的认知功能储备能量的年龄差异和训练的迁移效应。结果表明认知干预措施可在一定程度上改善老年人的记忆,同时也显示了在发展的储能和对图形的迁移效应方面,老年人明显不如青、少年,而青年与少年则彼此相近。  相似文献

The processes of inhibiting uninstructed motor responses were examined to identify age differences. Younger adults (n = 40) and older adults (n = 38) participated in two experiments using the Stimulus‐Response Compatibility task. They were asked to push the switch on the side contralateral to the stimulus. The results indicated that responses induced by visual stimuli were gradually inhibited as a result of repeated trials on the contralateral (not‐induced) side, and no age differences were noted. The addition of a color‐discrimination task to the Stimulus‐Response Compatibility task inhibited impulsive response induced by visual stimuli in younger adults only. These results indicate that certain processes of inhibiting motor responses are affected by aging, whereas other processes remain unaffected.  相似文献

Prior research has investigated the recruitment of inhibition in the use of science/mathematics concepts in tasks that require the rejection of a conflicting, nonscientific initial concept. The present research examines if inhibition is the only EF skill recruited in such tasks and investigates whether shifting is also involved. It also investigates whether inhibition and/or shifting are recruited in tasks in which the use of science/mathematics concepts does not require the rejection of an initial concept, or which require only the use of initial concepts. One hundred and thirty‐three third‐ and fifth‐grade children participated in two inhibition and shifting tasks and two science and mathematics conceptual understanding and conceptual change (CU&C) tasks. All the tasks were on‐line, and performance was measured in accuracy and RTs. The CU&C tasks involved the use of initial concepts and of science/mathematics concepts which required conceptual changes for their initial formation. Only in one of the tasks the use of the science/mathematics concepts required the concurrent rejection of an initial concept. The results confirmed that in this task inhibition was recruited and also showed that the speed of shifting was a significant predictor of performance. Shifting was a significant predictor of performance in all the tasks, regardless of whether they involved science/mathematics or initial concepts. It is argued that shifting is likely to be recruited in complex tasks that require multiple comparisons of stimuli and the entertainment of different perspectives. Inhibition seems to be a more selective cognitive skill likely to be recruited when the use of science/mathematics concepts requires the rejection of a conflicting initial concept.  相似文献

The business-to-business selling function has changed over the years, with more informed and demanding buyers, prompting firms to move toward a more consultative, solution-selling approach. While these changes have been the focus of extensive research in the personal selling and sales management domain, the customer side of the interaction dyad requires more examination. Even within the context of the customer side, insufficient attention has been paid to the purchasing function in business-to-business (B2B) selling research. Given the increased importance in customer organizations of the purchasing function, this article presents a literature review that highlights the purchasing function's personal selling and sales management needs and argues that, as the purchasing function becomes more important and its needs evolve, personal selling and sales strategies also need to evolve. The article highlights areas for future research in this domain.  相似文献

In the UK in recent years, there has been a considerable and sustained increase in both levels of personal debt and over‐indebtedness. This commentary argues that recent UK policy formulation on personal debt management has sidelined problematic macroscopic political and economic changes by locating personal debt as a problem of individual financial incompetence. Through specific institutions, tools, techniques and practices, certain configurations of people in debt have been rendered knowable and changeable. In doing so, public policies that have brought about a greater need for a greater number of people to rely on personal debt remain largely beyond public view and have instead been reconstituted as problems of access to financial capability training.

This paper has traced Bion’s discovery of alpha function and its subsequent elaboration. His traumatic experiences as a young tank commander in World War I (overlaid on, and intertwined with, childhood conflicts) gave him firsthand exposure to very painful emotions that tested his capacity to manage. Later, in the 1950s, after his analysis with Melanie Klein and marriage to Francesca Bion, he undertook the analysis of psychotic patients and learned how they disassembled their ability to know reality as a defense against unbearable emotional truths in their lives. This led Bion to identify an aspect of dreaming that was necessary in order for reality experience to be given personal meaning so that one may learn from experience. Simultaneous with working out this new theory of dreaming, Bion also revisited his World War I experiences that had remained undigested and all these elements coalesced into a selected fact – his discovery of alpha function. In subsequent writings, Bion explored the constituent factors of alpha function, including the container/contained relationship, the PS?D balance, reverie, tolerated doubt and other factors which I have termed the ‘Constellation for Thinking’.  相似文献

The “prosperity gospel” is an understudied feature of the religious landscape of the United States. Little is known about the social patterning of prosperity gospel beliefs. We focus on two core dimensions of socioeconomic status (SES)—education and income—as potential influences. Our analyses of data from the Pew Forum on Religion & Public Life's 2006 Survey of Pentecostals produce three findings. First, education and income have negative and mostly independent associations with prosperity gospel beliefs. Second, SES‐based patterns remain after accounting for other attributes of the religious role. Third, while most education‐based differences are contingent upon the attributes of the religious role, these contingencies are not replicated for income‐based differences. These observations reinforce the long‐standing claim that SES plays a pivotal—and complex—role in the social patterning of religious beliefs.  相似文献

The roles of belief in a just world (BJW) and discrimination against ones' group in perceptions of personal discrimination were examined. Female participants (n = 63) were personally discriminated against in a laboratory setting. We manipulated whether the experimenter appeared to discriminate against other participants, which presumably made the presence of personal discrimination less ambiguous, or did not appear to discriminate against others, which presumably made personal discrimination more ambiguous. In the no group discrimination condition, but not in the group discrimination condition, participants' perceptions of being personally discriminated against depended on individual differences in BJW: Women with a strong BJW perceived less personal discrimination than those with a weak BJW. Also, strong BJW women in the group discrimination condition perceived less personal discrimination than strong BJW women in the no group discrimination condition.  相似文献
