There is scant research on how the parenting practices of custodial grandmothers affect the psychological adjustment of grandchildren in their care. Yet, the findings from a handful of prior studies suggest the relevance of the Family Stress Model (FSM) to these caregivers. The present study further tested the FSM with baseline data from 343 custodial grandmothers (Mage?=?58.5 years) enrolled in a clinical trial of the efficacy of interventions for improving the well-being of their families. Not only was this “help-seeking” sample atypical of prior FSM studies, but also unique to the present study was our addition of multiple parenting practices, self-reported and clinical ratings of grandmothers’ distress, and reports of grandchildren’s internalizing and externalizing difficulties from grandchildren and grandmothers. Mplus 7.31 was used to test a model where the effect of grandmother distress on grandchildren’s internalizing and externalizing difficulties was hypothesized to be indirect through five distinct parenting practices. The findings regarding both the measurement and structural models fit the observed data well, and invariance was largely found across grandchildren’s gender and age (4–7 vs. 8–12). Although grandchildren’s self-reported internalizing and externalizing difficulties were unrelated to grandmothers’ distress and parenting practices, the grandmothers’ reports of these outcomes were generally related to their own distress and parenting practices as hypothesized. However, considerable variation was found across the five parenting practices in terms of their relationships to the other FSM constructs. We conclude that data from multiple informants and measures of assorted parenting practices are essential to future research and practice. 相似文献

Contrasting hypotheses were posed to test the effect of Facebook exposure on self-esteem. Objective Self-Awareness (OSA) from social psychology and the Hyperpersonal Model from computer-mediated communication were used to argue that Facebook would either diminish or enhance self-esteem respectively. The results revealed that, in contrast to previous work on OSA, becoming self-aware by viewing one's own Facebook profile enhances self-esteem rather than diminishes it. Participants that updated their profiles and viewed their own profiles during the experiment also reported greater self-esteem, which lends additional support to the Hyperpersonal Model. These findings suggest that selective self-presentation in digital media, which leads to intensified relationship formation, also influences impressions of the self. 相似文献

Three series of experimental tests were conducted on subjects under both elevated and depressed thermal conditions. Tripartite series consisted of whole-body immersion excepting the head, whole-body immersion excepting the head and response limb, and immersion of the discrete-response limb. Measures of physiological and behavioural responses were made at sequential .4 degrees C changes during whole-body immersions and approximately 5 degrees C changes of water temperature during the immersion of a limb only. Results suggested that velocity of nerve conduction decreased with thermal depression. Premotor, motor, simple, and choice reaction times varied differentially as a function of the hot and cold conditions. Implications of these differential effects on neuromuscular function are examined with respect to person-machine performance in artificially induced or naturally occurring extremes of ambient temperature. 相似文献

The present research investigated whether the attribution process through which people explain self‐disclosures differs in text‐based computer‐mediated interactions versus face to face, and whether differences in causal attributions account for the increased intimacy frequently observed in mediated communication. In the experiment participants were randomly assigned to a face‐to‐face or computer‐mediated interaction with a confederate who made either high‐ or low‐intimacy self‐disclosures. Results indicated that computer‐mediated interactions intensified the association between disclosure and intimacy relative to face‐to‐face interactions, and this intensification effect was fully mediated by increased interpersonal (relationship) attributions observed in the computer‐mediated condition. The article presents an attributional extension of the hyperpersonal model ( Walther, 1996 ) by demonstrating the role of causal attributions in interpersonal intensification processes in text‐based computer‐mediated interactions. 相似文献

Four participants constructed face composites, of familiar and unfamiliar targets, using Pro-Fit, with reference images present or from memory. The "mean" of all 4 composites, created by morphing (4-morph) was rated as a better likeness than individual composites on average and was as good as the best individual likeness. When participants attempted to identify targets from line-ups, 4-morphs again performed as well as the best individual composite. In a second experiment, participants familiar with target women attempted to identify composites, and the trend showed better recognition from multiple composites, whether combined or shown together. In a line-up task with unfamiliar participants, 4-morphs produced most correct choices and fewest false positives from target-absent or target-present arrays. These results have practical implications for the way evidence from different witnesses is used in police investigations. 相似文献

Reaction times in a mental rotation task were measured across a diverse population that sorted into two groupings based on overall variability. Although both the low- and the high-variance groups produced data that displayed the trends typical of mental rotation, the two groups' reaction time sequences had very different autocorrelation functions. Power spectra derived from the two groups' data showed the presence of distinctive noise processes with long memory. Normal levels of variance were associated with 1/f noise, whereas high-variance data had substantial traces of random walk contour. These findings provide new perspectives on cognitive assessments of attention dysfunction. 相似文献

This study used a latent difference score growth model to investigate how changes in family structure (biological father and stepfather residence) and maternal employment are associated with American children's externalizing problem behaviours (EPB) from ages 4–10 and whether these associations vary by children's level of self-regulation. For all 4-year-old children, living with a biological father at age 4 was associated with reductions in EPB at ages 4–6 and later years, with no variation by child self-regulation. Living with a stepfather at age 4 was associated with higher levels of EPB at age 4; however, for less-regulated children, stepfather residence at ages 4 and 8 was associated with reductions in EPB between ages 4–6 and 8–10, respectively. Greater employment hours were associated with increased EPB in the next 2 years for less-regulated children of all ages; however, except for the age 4–6 transition, there was a lagged association that reduced behaviour problems after 2 years and outweighed short-term increases. 相似文献

We selectively review the progress of research on the psychology of time during the past 125 years, starting with the publication of the first English-language psychological journal, The American Journal of Psychology. A number of important articles on the psychology of time appeared in this journal, including the widely cited early article by Nichols (1891). The psychology of time is a seminal topic of psychological science, and although it entered a phase of decline and even moribund neglect, the past several decades have seen a prominent renaissance of interest. This renewed vigor represents the rebirth of the recognition of the centrality of the psychology of time in human cognition and behavior. Our selective overview highlights a number of strands of progress and how they have helped lead to the present, in which the cognitive neuroscience of time and timing in the brain is one of the most fervent and fertile modern areas of brain research. We also discuss some remaining challenges and potential lines of progress. 相似文献

Comments on the original article, "Guidelines for psychological practice with lesbian, gay, and bisexual clients," by the American Psychological Association (see record 2011-19419-001). Guideline 3 of the acknowledges the diversity of human sexual orientation and that "efforts to change sexual orientation have not been shown to be effective or safe" (p. 14). As noted in the Report of the American Psychological Association Task Force on Appropriate Therapeutic Responses to Sexual Orientation (APA, 2009), "Current criteria for effective treatments and interventions are specific in stating that to be considered effective, an intervention has consistent positive effects without serious harmful side effects [emphasis added]" (p. 26). The present authors note that half a century of scientific research on a variety of sexual orientation change efforts (SOCE) has not demonstrated their effectiveness according to the criteria of consistent positive effects and absence of serious harmful effects. Guideline 3 (APA, 2012) therefore urges psychologists to closely assess the motivations of clients who seek SOCE in the context of stigma and internalized prejudice about their non-heterosexual orientation. In addition, the guideline also recommends that psychologists obtain truthful, thorough, and thoughtful informed consent and that they focus on personal integration instead of sexual orientation change. The burden of proof has been on advocates of SOCE, and the present authors assert that it has not been met. (PsycINFO Database Record (c) 2012 APA, all rights reserved). 相似文献
