A program of early psychosocial support for low-income parents and infants was established at an inner-city family health center. Such a program meets many of the criteria of successful early psychological intervention by (1) beginning during the prenatal period and extending through the first 3 years of life, (2) providing professional and peer support to the parent-infant system, (3) responding to the social as well as psychological needs of low-income parents, and (4) embedding preventive intervention into an accessible neighborhood setting.  相似文献

This paper presents a learning theory pertinent to dynamic decision making (DDM) called instancebased learning theory (IBLT). IBLT proposes five learning mechanisms in the context of a decision‐making process: instance‐based knowledge, recognition‐based retrieval, adaptive strategies, necessity‐based choice, and feedback updates. IBLT suggests in DDM people learn with the accumulation and refinement of instances, containing the decision‐making situation, action, and utility of decisions. As decision makers interact with a dynamic task, they recognize a situation according to its similarity to past instances, adapt their judgment strategies from heuristic‐based to instance‐based, and refine the accumulated knowledge according to feedback on the result of their actions. The IBLT's learning mechanisms have been implemented in an ACT‐R cognitive model. Through a series of experiments, this paper shows how the IBLT's learning mechanisms closely approximate the relative trend magnitude and performance of human data. Although the cognitive model is bounded within the context of a dynamic task, the IBLT is a general theory of decision making applicable to other dynamic environments.  相似文献

We propose that when individuals make a decision for themselves they weight attributes more uniformly compared to when they give advice. In Study 1, 138 participants were given a hypothetical choice between two jobs varying on two dimensions and asked either to choose for themselves, offer advice to a best friend, or offer advice to an acquaintance. We hypothesized that respondents offering advice would favor the option with the higher value on the more important dimension. More participants in the acquaintance condition recommended the job with a higher value on the important dimension than participants making the choice for themselves. Study 2 (N=62) tested the hypothesis in a situation where the options consisted of three dimensions. One option was relatively high on two of the three dimensions and the other option was relatively high on the remaining ‘socially important’, or ‘prominent’, dimension. The uniform weighting hypothesis for self‐choice predicts higher frequency of choice for the former option. Data were consistent with this prediction. Study 3 (N=170) tested the hypothesis in students' choice of major at the university. We made use of an actual event, a pending university budget cut, that would require some students to change majors. Participants either made the decision for themselves, made a recommendation to a student in their same department, or made a recommendation to a student in another department facing the analogous dilemma. Replicating the findings of the first two studies, participants offering advice to a student in another department suggested staying with their current major significantly more than participants making the choice for themselves.

Power plants lose efficiency when the air preheater elements are not replaced or cleaned as they deteriorate. Replacing is more expensive than cleaning but more secure to preserve power and lifetime. How many baskets should be then replaced and how many cleaned to achieve ‘satisficing’ goals of cost, power and lifetime? We design deterministic/stochastic goal programming approaches to this problem and develop a decision case for usual preheaters. Some discrepancies in results between both approaches appear, the deterministic model advising to replace less baskets than the stochastic, which is plausible due to the risk variable.

Mood, personal merit, and/or its perception have been suggested to be mediating factors in testosterone responses to competition. Previously we have found that personal contribution and attribution were related to testosterone levels after successful competition. To confirm such associations, two basketball teams (n = 17 players) that emerged as winners in two actual matches were studied. Salivary testosterone levels and mood were measured before and after the games. Individual contribution to the outcome was assessed, and personal satisfaction and causal attribution of outcome were reported by players. Testosterone concentrations increased to near significance in Team 1 but not in Team 2, who attributed their victory more to luck than did Team 1. This latter team showed notably decreased vigor, and both teams showed fatigue at the end of the match. Post‐match testosterone levels were only significantly, negatively related to external attribution. The results support the idea that causal attribution of the outcome is contributing to the variance of the testosterone responses to real confrontations where the outcome is highly dependent on personal merit.

The present research used an intersectional analysis in examining whether women and men who have, versus do not have, cross-category friendships differ in what they value as important in a close friendship. Parallel analyses were conducted to examine cross-orientation and cross-race friendships across gender and identity status (minority and majority), with age as a covariate for all analyses. Participants were 1415 adult women and men, ranging in age from 18-80, residing in the United States, who completed a friendship profile questionnaire by reporting basic demographic information about themselves and their close friends. Participants’ importance ratings of six different friendship values were utilized to interrogate existing friendship patterns. Three general friendship values (trust and honesty, respect friend as person, there when needed) and three cross-identity salient friendship values (similar lives & experiences, similar values, nonjudgmental) were considered. Individuals with and without cross-category friendships did not significantly differ in their ratings for any of the three general friendship values. Individuals with cross-orientation and cross-race friendships placed less importance on similar lives & experiences than those with no such friendships. Other cross-identity salient friendship values were uniquely related to cross-orientation and cross-race friendship patterns. Although women rated all six friendship values as more important than did men, women and men displayed similar friendship value patterns across cross-category friendships and identity. These findings are discussed in the context of feminist intersectional theory.  相似文献

Parenting an LGBTQ (lesbian, gay, bisexual, transgender, or queer) identified child presents unique opportunities for growth and development. This study focused on self‐reported perceptions of the positive aspects of being the parent of an LGBTQ child. Participants (N = 142) were mothers (83.8%) and fathers (16.2%) of LGBTQ identified individuals who responded to an open‐ended online survey. Thematic analysis revealed five primary themes: Personal Growth (open mindedness, new perspectives, awareness of discrimination, and compassion), Positive Emotions (pride and unconditional love), Activism, Social Connection, and Closer Relationships (closer to child and family closeness). The practice implications of these findings for supporting parents in envisioning positive relationship outcomes for themselves and their children are highlighted in the discussion.  相似文献
