The purpose of this study was to examine developmental change and the influence of shyness on social problem-solving (SPS). At 24, 36, and 48 months, children (N = 570) were observed while interacting with an unfamiliar peer during an SPS task and at 24 months, maternal report of shyness was collected. Results showed that across the full sample, children displayed low but stable levels of withdrawn SPS and increasing levels of SPS competence over development. In addition, results showed multiple trajectories of withdrawn and competent SPS. Shyness was associated with high-increasing and high-decreasing withdrawn SPS trajectories compared with the low-increasing withdrawn SPS trajectory. Shyness was also associated with the low-increasing compared with the high-increasing SPS competence trajectory. Findings demonstrate the development of SPS competence over early childhood, and the influence of early shyness on this developmental course, with some shy children showing improvement in SPS skills and others continuing to show SPS difficulties over time. 相似文献

Increased interest in the prevention of illness underscores the importance of understanding how people evaluate their health. This study investigated self-report measures of health status, medical complaints, and psychosocial factors in 455 undergraduates. After controlling for neuroticism, regression analyses indicated that positive mood, negative mood, perceived vulnerability to illness, and vitality were significant contributors to self-assessed health independent of physical symptoms and diseases. Together, psychosocial factors accounted for more variance in health assessments (R2 = .44) than did disease and symptom reports alone (R2 = .25; p. < .01 for all betas). These results demonstrate the strong association of psychosocial stares with evaluations of health and suggest that physical discomfort may play a relatively minor role in how "healthy" we feel. 相似文献

The aim of the present study was to establish if patients with major depression (MD) exhibit a memory bias for sad faces, relative to happy and neutral, when the affective element of the faces is not explicitly processed at encoding. To this end, 16 psychiatric out-patients with MD and 18 healthy, never-depressed controls (HC) were presented with a series of emotional faces and were required to identify the gender of the individuals featured in the photographs. Participants were subsequently given a recognition memory test for these faces. At encoding, patients with MD exhibited a non-significant tendency towards slower gender identification (GI) times, relative to HC, for happy faces. However, the GI times of the two groups did not differ for sad or neutral faces. At memory testing, patients with MD did not exhibit the expected memory bias for sad faces. Similarly, HC did not demonstrate enhanced memory for happy faces. Overall, patients with MD were impaired in their memory for the faces relative to the HC. The current findings are consistent with the proposal that mood-congruent memory biases are contingent upon explicit processing of the emotional element of the to-be-remembered material at encoding. 相似文献

Using the perspective of instructional conversation, we investigated how one teacher regulated student participation and conceptual reasoning in the middle-school mathematics classroom. We examined the elicitations—questions and provocative statements—made by the teacher over a four-day algebra lesson. Analyses showed how the teacher systematically regulated the level of cognitive complexity of his elicitations in reaction to students' responses. When students gave inaccurate or incomplete answers, the teacher tended to reduce the level of cognitive complexity needed to respond to a subsequent elicitation, with the apparent impact being that he scaffolded participation and reasoning. When students provided responses that were mathematically accurate, the teacher usually increased the elicitation level, which subsequently engaged students in more sophisticated forms of reasoning. 相似文献

The decision strategy used to select a choice set from an array of alternative options is known to affect the composition of the final choice set. Specifically, individuals incorporate more answers into their choice set when it is created by eliminating implausible items than when the set is created through the inclusion of plausible options. This difference is accounted for in a decision framework that posits a general reluctance to change the status quo (i.e., actively include or exclude an item). We extended this work to investigate, not only the decisions themselves, but also metacognitive judgments (i.e., confidence in the accuracy of the choice set). In two face recognition experiments, we tested the impact of decision strategy (Experiment 1) and confidence judgment strategy (Experiment 2) on the confidence–accuracy relationship. In Experiment 1, participants completed two blocks of recognition trials, one under inclusion (marking previously seen faces) and one under elimination (marking previously unseen faces) instructions. We observed superior resolution (i.e., discrimination between correct and incorrect) for inclusion trials, but only when they were completed prior to use of the elimination strategy. In Experiment 2, all participants completed face recognition trials under inclusion instructions, but we manipulated the strategy used to assess confidence. Again, we observed a significant impact of strategy on confidence–accuracy resolution. Thus, we observed that both the strategy employed to reach a decision and that employed to assess confidence affected the confidence–accuracy relationship. We discuss theoretical and applied (particularly for eyewitness identification and multiple‐choice testing) implications. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

This investigation examines how self-identified Christians in the Midwest U.S. understand and work for social justice, with a focus on their process of social justice development and the role of religious congregations in promoting social justice. Using a grounded theory analysis of 15 in-depth interviews, results indicated multiple understandings of social justice such as meeting basic needs, fixing social structures and systems to create equal distributions of resources, promoting human rights and dignity, and as a religious responsibility. Participants also described a process of social justice development facilitated by exposure to injustice, mentors, educating others, and the importance of finding a social justice community. Distinct personal barriers to social justice engagement were identified such as resources and negative emotions, whereas congregational leadership was important for congregational involvement. General frustration with congregations was expressed regarding low social justice engagement; however, participants balanced this frustration with hope for the positive potential of congregations to promote social justice. Together these findings show multifaceted understandings of social justice and a dynamic process of social justice development for these self-identified Christians. Implications for future research and partnership with religious individuals and congregations also are discussed. 相似文献

This exploratory study was conducted to gain information on an emerging form of prostitution—online prostitution. Additionally, this study focused on male prostitution, as it is the type less likely to gain attention in prostitution research. This study used 83 websites that advertise male escorts to explore the type of information provided to potential customers. The results indicate that these male escorts provide a variety of information (e.g., prices, services). In addition, some differences were found between sites depending on the potential customer (e.g., male, female). The importance of sex research and implications for future research also are discussed. 相似文献

The current study examined the potential influence of existing spatial knowledge on the coding of new spatial information. In the Main experiment, participants learned the locations of five objects before completing a perspective-taking task. Subsequently, they studied the same five objects and five additional objects from a new location before completing a second perspective-taking task. Task performance following the first learning phase was best from perspectives aligned with the learning view. However, following the second learning phase, performance was best from the perspective aligned with the second view. A supplementary manipulation increased the salience of the initial view through environmental structure as well as the number of objects present. Results indicated that the initial learning view was preferred throughout the experiment. The role of assimilation and accommodation mechanisms in spatial memory, and the conditions under which they occur, are discussed. 相似文献

High-resolution annular dark field imaging has been used to study small precipitates in the Al matrix of 6XXX-series aluminium alloys. Cu-containing columns in precipitates were imaged by atomic number contrast along a 〈100〉 matrix direction. At an under-aged condition, large, lath-shaped particles of the Cu-containing Q′-phase were observed at grain boundaries. At over-aged conditions, Q′ was the main matrix phase. In both cases the laths showed an Al {150} habit plane. A precursor phase was found, with different arrangement of Cu-rich columns from that of the Q′-phase and sharing Al {100} habit planes. Precipitates containing elements of both the Q′-phase and the precursor were found to be common. Annular dark field imaging can differentiate directly between phases. The method complements and aids interpretation of conventional high-resolution TEM images and nano beam diffraction observations. The results obtained contribute to an improved understanding of the crystallography of the precursor and details of the structural transformation taking place during the precipitation process. 相似文献
