A distinction between parental behavioral control and psychological control has been elucidated in the literature, yet far less is known about the role of psychological control in youth adjustment broadly or risky behavior in particular. We examined the interrelationship of maternal psychological control, youth psychosocial adjustment, and youth risk behaviors among African American single mother-youth (11–16-year old) dyads (n = 194), families in which youth are more vulnerable to adjustment problems and risky behavior than Caucasian youth or youth from intact homes. Higher levels of maternal psychological control were associated with increased youth psychosocial adjustment problems as well as increased youth risk behavior, after statistically controlling for one domain of behavioral control, parental knowledge about a child’s whereabouts and activities. Furthermore, youth externalizing problems mediated the relation between psychological control and risk behavior. The findings suggest that parenting programs targeting risk behavior among African American youth may benefit from including psychological control among the parenting dimensions that are targeted.  相似文献

This investigation illustrates men’s and women’s change in femininity, and individual differences in change in femininity from early (age 33 or 35) to late (age 78 or 85) adulthood. Members of three long-term longitudinal samples (total N = 327) provided California Psychological Inventory (CPI) Femininity scale scores, collected a maximum of five times. Application of longitudinal hierarchical linear modeling indicates: (1) both men and women show significant variability in initial level and change in femininity, (2) gender predicts both individuals’ initial level and change in femininity—the average man, initially low in femininity, becomes significantly higher in femininity across the lifespan; the average woman, initially high in femininity, becomes significantly lower in femininity across the lifespan, (3) change in femininity is unconnected to marital or parental status, and (4) change in femininity is connected to psychological health level for women only—more psychologically healthy women show a decline in femininity, while less healthy women increase their femininity level. Overall, results support Jung’s androgyny hypothesis of a cross-over of gender roles in men and women, but do not support Gutmann’s hypothesis that such cross-over is tied to “parental emergency.” Additional exploration of the data indicates Gough and Bradley’s (1996) CPI-derived personality types also predict femininity initial level for women and femininity change for men.  相似文献

We explored the claim that structural priming is a case of implicit learning within the language production system. The experiment began with a baseline phase, in which we assessed participants’ rates of production for double object and prepositional object constructions. Then participants were biased toward the production of either the double object or prepositional object construction. Finally, we again assessed participants’ rates of production for the target constructions. Consistent with claims that structural priming is a case of implicit learning, we found that biasing participants toward the prepositional object construction produced stronger cumulative priming effects than did biasing participants toward the double object construction. We also found that individual differences in implicit learning were marginally correlated with overall rates of production for the double object construction. Participants who scored better on the learning task tended to produce fewer double object constructions.  相似文献

Adults can improve their performance on many perceptual tasks with training, but when does the response to training become mature? To investigate this question, we trained 11‐year‐olds, 14‐year‐olds and adults on a basic auditory task (temporal‐interval discrimination) using a multiple‐session training regimen known to be effective for adults. The adolescents all began with performance in the adult range. However, while all of the adults improved across sessions, none of the 11‐year‐olds and only half of the 14‐year‐olds did. The adolescents who failed to learn did so even though the 10‐session training regimen provided twice the number of sessions required by adults to reach asymptotic performance. Further, over the course of each session, the performance of the adults was stable but that of the adolescents, including those who learned, deteriorated. These results demonstrate that the processes that underlie perceptual learning can continue to develop well into adolescence.  相似文献

Many human activities involve a risk of physical harm. However, not much is known about the specific brain regions involved in decision making regarding these risks. To explore the neural correlates of risk perception for physical harms, 19 participants took part in an event-related fMRI study while rating risky activities. The scenarios varied in level of potential harm (e.g., paralysis vs. stubbed toe), likelihood of injury (e.g., 1 chance in 100 vs. 1 chance in 1,000), and format (frequency vs. probability). Networks of brain regions were responsive to different aspects of risk information. Cortical language- processing areas, the middle temporal gyrus, and a region around the bed nucleus of stria terminalis responded more strongly to high- harm conditions. Prefrontal areas, along with subcortical ventral striatum, responded preferentially to high- likelihood conditions. Participants rated identical risks to be greater when information was presented in frequency format rather than probability format. These findings indicate that risk assessments for physical harm engage a broad network of brain regions that are sensitive to the severity of harm, the likelihood of risk, and the framing of risk information.  相似文献

Interpreting spatial language in image captions   总被引:1,自引:0,他引:1  
The map as a tool for accessing data has become very popular in recent years, but a lot of data do not have the necessary spatial meta-data to allow for that. Some data such as photographs however have spatial information in their captions and if this could be extracted, then they could be made available via map-based interfaces. Towards this goal, we introduce a model and spatio-linguistic reasoner for interpreting the spatial information in image captions that is based upon quantitative data about spatial language use acquired directly from people. Spatial language is inherently vague, and both the model and reasoner have been designed to incorporate this vagueness at the quantitative level and not only qualitatively.  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

Abstract Europe's religious “demise” is well reported and often lamented in missionary circles. This article aims to offer a contrary perspective using the common approach of evangelism: “double listening”. The task is to listen to our culture and our text in conversation and to discover what the text is saying afresh to our needs and values. It is, however, largely expected that this double listening will yield itself to the means by which Christ can change and counter culture. But what if our double listening reveals the deafness of evangelism to the voice of Christ in our culture? This paper aims to explore the widespread religious experience in Europe of God's absence, and how it prompts us to re‐examine the stories of Jesus and the rhetoric we use to describe Europe's religious life. It contends that much evangelism in Europe is too inhospitable or unsophisticated to see this absence as anything other than something we should rush to fill with the latest model of our reliable 24/7 god. However, it might be leading us to acknowledge something about the life of faith that Jesus seems to offer in much of his teaching. Europe's resistance to organized religion is painful to experience, but it might be inviting us into a fresh conversion to what God is doing beyond our walls. If so, evangelism will have to learn a fresh humility as well as to provide the fresh energy to discover and partner God there.  相似文献

This paper explores the role of member participation in decision-making (PDM) from an organizational learning (OL) perspective. Community-based organizations (CBOs) serve as mediators between the individual and the local community, often providing the means for community member participation and benefiting organizationally from members' input. Community psychologists have recognized these benefits; however, the field has paid less attention to the role participation plays in increasing CBOs' capacity to meet community needs. We present a framework for exploring how CBO contextual factors influence the use of participatory decision-making structures and practices, and how these affect OL. We then use the framework to examine PDM in qualitative case study analysis of four CBOs: a youth development organization, a faith-based social action coalition, a low-income neighborhood organization, and a large human service agency. We found that organizational form, energy, and culture each had a differential impact on participation in decision making within CBOs. We highlight how OL is constrained in CBOs and document how civic aims and voluntary membership enhanced participation and learning.  相似文献

Supportive Non-Parental Adults (SNPAs), or non-parental adults who provide social support to youth, are present in the lives of many adolescents; yet to date, a guiding framework for organizing the existing literature on the provision of support provided by multiple types of SNPAS, such as teachers, natural mentors, and extended family members, as well as to inform future research efforts, is lacking. The aim of the current paper is to utilize the well-established lens of social support to integrate, across this broad range of literatures, recent findings regarding associations between SNPAs and four indices of adolescent psychosocial adjustment: academic functioning, self-esteem, and behavioral and emotional problems. Beyond offering an integrative framework for understanding the link between SNPAs and adolescent functioning, the issues reviewed here have potentially far-reaching consequences for adolescents and their families, as well as the professionals working with adolescents and their families in the health care, school, and community settings.  相似文献
