Experiencing maltreatment in early childhood predicts poor parasympathetic regulation, characterized by low baseline parasympathetic activity and strong withdrawal of parasympathetic influence in response to tasks. The Promoting First Relationships® (PFR) program improves parental sensitivity toward young children in families identified as maltreating. Using a subsample from a randomized control trial, we examined whether parental participation in PFR had lasting effects on toddlers’ parasympathetic regulation, as measured by respiratory sinus arrhythmia (RSA), relative to a resource and referral control condition. In addition, we examined whether parental sensitive and responsive behavior mediated or moderated associations between parent treatment group and children's RSA. More than 6 months after completing treatment, 29 families in the PFR condition and 30 families in the control condition were visited at home, and toddlers’ RSA was assessed at baseline and during five moderately challenging tasks. Groups did not differ in baseline RSA, but differed in RSA reactivity to the tasks. Across tasks, toddlers of parents in the control condition manifested significantly larger RSA decreases than toddlers of parents in the PFR condition. Parental behavior showed divergent associations with RSA change for toddlers of parents in the PFR versus control condition, with PFR treatment predicting RSA change ranging from small decreases to increases in toddlers of parents who showed the most sensitive, responsive behavior in the 6 months following treatment. This preliminary study showed that the same intervention that improved parenting also improved toddlers’ parasympathetic regulation in response to everyday activities, warranting further experimental investigation. 相似文献

Although often credited with prompting a paradigm shift in social comparison theory, T. A. Wills's (1981) downward comparison (DC) theory has received some criticism recently. In particular, several recent studies have failed to find support for T. A. Wills's (1981) contention that threat and accompanying negative affect lead to a desire for DC. These apparent failures have led some investigators to question basic principles of the theory. To resolve this controversy, 5 studies were conducted examining preferred comparison level (PCL) after performance; 4 of the studies also assessed change in this preference. Results supported DC theory, but with modifications. Specifically, individuals who performed poorly lowered their PCLs. Under some circumstances, this "downward shift" included an increased interest in "true" DC--comparing with worse-off others. A reconciliation of these results with those of previous studies is offered. 相似文献

Two studies are presented that challenge the evidentiary basis for the existence of evolved sex differences in jealousy. In opposition to the evolutionary view, Study I demonstrated that a sex difference in jealousy resulting from sexual versus emotional infidelity is observed only when judgments are recorded using a forced-choice response format. On all other measures, no sex differences were found; both men and women reported greater jealousy in response to sexual infidelity. A second study revealed that the sex difference on the forced-choice measure disappeared under conditions of cognitive constraint. These findings suggest that the sex difference used to support the evolutionary view of jealousy (e.g., D. M. Buss, R. Larsen, D. Westen, & J. Semmelroth, 1992; D. M. Buss et al., 1999) likely represents a measurement artifact resulting from a format-induced effortful decision strategy and not an automatic, sex-specific response shaped by evolution. 相似文献

Two experiments provide initial evidence that specific emotional states are capable of creating automatic prejudice toward outgroups. Specifically, we propose that anger should influence automatic evaluations of outgroups because of its functional relevance to intergroup conflict and competition, whereas other negative emotions less relevant to intergroup relations (e.g., sadness) should not. In both experiments, after minimal ingroups and outgroups were created, participants were induced to experience anger, sadness, or a neutral state. Automatic attitudes toward the in- and outgroups were then assessed using an evaluative priming measure (Experiment 1) and the Implicit Association Test (Experiment 2). As predicted, results showed that anger created automatic prejudice toward the outgroup, whereas sadness and neutrality resulted in no automatic intergroup bias. The implications of these findings for emotion-induced biases in implicit intergroup cognition in particular, and in social cognition in general, are considered. 相似文献

The goal of the present study was to investigate whether object-based attention effects differ across the cerebral hemispheres. Previous research has suggested that object-based attention is preferentially lateralized to the left hemisphere (Egly, Driver, & Rafal, 1994; Egly, Rafal, Driver, & Starrveveld, 1994). However, work by Vecera (1994) has suggested that these previous studies may have failed to obtain a pure measure of object-based attention. The present study applied modified versions of Duncan's (1984) seminal object-based attention paradigm. Subjects were typically presented with one target object to a single visual field (one-object display), two target objects to the same visual field (two-object unilateral display), or two target objects to different visual fields (two-object bilateral display). In all three experiments, response accuracy was higher for the one-object displays than for the two-object displays. Most important, this object-based cost was especially severe when selection of two target elements was isolated to the right visual field (left hemisphere). We confirmed that this effect was specific to object-based attention in three different ways: Experiment 1 manipulated stimulus distance, as recommended by Vecera; Experiment 2 ensured that target selection was based on nonspatial attributes; and Experiment 3 used overlapping displays, as in Duncan (1984). Collectively, the data are in accord with previous conclusions that object-based attention is a specialized form of orienting subserved by lateralized cortical brain mechanisms. However, contrary to previous research, it appears that it is the right hemisphere, and not the left hemisphere, that is preferentially biased for committing object-based attention to elements in the visual environment. 相似文献

This study investigated how global personality traits and teasing history are related to participants' emotional and behavioral reactions to an actual teasing event. College undergraduates (N = 108) worked on a task with a same-sex confederate. While interacting, the confederate either teased participants about how slowly they were working on the task or made a benign comment about the nature of the task. Analyses revealed that even mild teasing can generate negativity towards the teaser and interaction. More interestingly, however, personality moderated reactions to teasing, as teasing condition interacted with each of the Big Five personality domains in theoretically meaningful ways. Childhood teasing history also moderated reactions to teasing, as frequent victims and frequent teasers responded in different ways. 相似文献

CONTEXT: People affected by schizophrenia show deficits in social interaction (Cramer, Bowen, & O'Neill, 1992); such a deficit may stem from an alteration in the representation of mental states. OBJECT: In this study we have examined 42 people affected by schizophrenia, diagnosed according to DSM-IV criteria, by testing them with an instrument (the Mach IV scale, Christie & Geis, 1970) assessing "Machiavellian Intelligence" according to Niccolò Machiavelli's assertions. Schizophrenic subjects were compared to a sample of normal controls, matched for age, sex, and education. OBJECTIVE: The aim of our study was to evaluate if there were correlations between the ability to understand other people's mental states and the capacity for interpreting "Machiavellian expressions." RESULTS: Results show that people affected by schizophrenia are less able to use Machiavellian-style "tactical" abilities than controls. CONCLUSION: Such a disability seems to be correlated to poor mentalising abilities. 相似文献

Iterated language learning experiments that explore the emergence of linguistic structure in the laboratory vary considerably in methodological implementation, limiting the generalizability of findings. Most studies also restrict themselves to exploring the emergence of combinatorial and compositional structure in isolation. Here, we use a novel signal space comprising binary auditory and visual sequences and manipulate the amount of learning and temporal stability of these signals. Participants had to learn signals for meanings differing in size, shape, and brightness; their productions in the test phase were transmitted to the next participant. Across transmission chains of 10 generations each, Experiment 1 varied how much learning of auditory signals took place, and Experiment 2 varied temporal stability of visual signals. We found that combinatorial structure emerged only for auditory signals, and iconicity emerged when the amount of learning was reduced, as an opportunity for rote-memorization hampers the exploration of the iconic affordances of the signal space. In addition, compositionality followed an inverted u-shaped trajectory raising across several generations before declining again toward the end of the transmission chains. This suggests that detection of systematic form-meaning linkages requires stable combinatorial units that can guide learners toward the structural properties of signals, but these combinatorial units had not yet emerged in these unfamiliar systems. Our findings underscore the importance of systematically manipulating training conditions and signal characteristics in iterated language learning experiments to study the interactions between the emergence of iconicity, combinatorial and compositional structure in novel signaling systems. 相似文献

Although women with disabilities are at increased risk for intimate partner violence (IPV), little is known about how this phenomenon impacts transitional-aged young women with disabilities who are still trying to master the developmental challenges of adolescence. This study explores risk factors for and prevalence of IPV by drawing on a population-based sample of women ages 18–21 with (N = 1,616,207) and without (N = 7,554,064) self-reported disabilities. Findings suggest that risk factors for IPV were more prevalent among sample members, as was past year experience of IPV. This study has implications for school social workers and disability service providers who interact with this population. 相似文献

The core question in this research asks what are the occupational and earnings consequences of place of education for immigrants with bachelor’s degrees or higher and whose highest degrees are in STEM fields compared to the native born. The focus is on immigrants with degrees in 15 countries which represent 88% of the immigration population of interest. In the analysis of the Canadian 2011 National Household Survey, STEM education is matched to three occupational outcomes: employment in STEM occupations, employment in other occupations usually requiring university bachelors’ degrees or higher, and employment in all other occupations which usually require less than university education. The Canadian-born and permanent legal residents whose highest degrees in STEM fields are from institutions in Canada, the USA, the UK, and in the case of the foreign born, France, are more likely to be employed in either STEM occupations or high-skilled occupations requiring bachelors’ degrees than are immigrants educated elsewhere; the latter are more likely to be employed in occupations that are not STEM related and usually do not require bachelor’s degrees. Immigrant disadvantages are stronger for earnings; regardless of the location of their STEM education, immigrants earn less than the Canadian born who received university degrees in Canada. However, the size of the gap varies by the country of the highest degree with the largest gaps, relative to the Canadian born and Canadian educated, observed for immigrants who are educated in countries other than Canada, the USA, the UK, and France. 相似文献
