Parents of 2-, 5-, 8-, and 11-month-olds used two scales we developed to provide information about their infants' facial experience with familiar and unfamiliar individuals during one week. Results showed large discrepancies in the race, sex, and age of faces that infants experience during their first year with the majority of their facial experience being with their primary caregiver, females, and other individuals of the same-race and age as their primary caregiver. The infant's age and an unfamiliar individual's sex were predictive of their time spent interacting with one another. Moreover, an unfamiliar individual's sex was predictive of the attention infants allocated during social interactions. Differences in frequency and length of interactions with certain types of faces, as well as in infant attention toward certain individuals, all likely contribute to the development of expertise in processing commonly experienced face types and deficiencies in processing less commonly experienced face types. 相似文献

This paper investigates the effects of war experiences across three different levels (individuals, groups, and contexts) on moral judgments related to violations of humanitarian norms. Competing hypotheses derived from different theoretical perspectives are empirically evaluated. Social psychological studies of war traditionally highlight a reversal of morality and group norms justifying violence against outgroups. Rationalistic models insist on the importance of realistic costs on the choice of individuals. As a complement to these traditions, we suggest that situations in which risks are generalized across group boundaries tend to provoke a strengthening of principles, such as humanitarian norms, that enable the protection of the material and symbolic integrity of a community. Multilevel analyses of the international People on War survey dataset (N = 8,121) show that support for the ingroup's struggle, at both individual and group levels, predicts stronger justification of violence. Simultaneously, at the context level, generalization of war‐related risks predicts stronger condemnation of violations of humanitarian principles. These findings are consistent with a collective vulnerability model and, only in part, with the intractable conflict model. 相似文献

In study 1, 148 married and unmarried childless Israeli women (mean age?=?25) indicated how often they think about having a child, their desired age for having a child, and justified not being mothers, with or without being primed with photographs of babies. Priming and marital status impacted the motivation for motherhood and the justifications for not being mothers. In study 2, the same procedure was used with 137 unmarried, childless Israeli women (mean age?=?24) whose gender role orientation was assessed. The impact of gender role orientation and priming on the motivation for motherhood and the justifications for not being mothers were complex, with femininity playing a much greater role than masculinity. The findings were discussed in the context of the myth of motherhood and its influence on the lives of women. 相似文献

This study examined (a) the relationships between posttraumatic stress disorder (PTSD) symptom clusters and marital intimacy among Israeli war veterans and (b) the role of self-disclosure and verbal violence in mediating the effects of PTSD avoidance and hyperarousal symptoms on marital intimacy. The sample consisted of 219 participants divided into 2 groups: ex-prisoners of war (ex-POWs; N = 125) and a comparison group of veterans who fought in the same war but were not held in captivity (N = 94). Ex-POWs displayed higher levels of PTSD symptoms and verbal violence and lower levels of self-disclosure than did controls. Although ex-POWs and controls did not differ in level of marital intimacy, they did, however, present a different pattern of relationships between PTSD clusters and intimacy. In ex-POWs, self-disclosure mediated the relations between PTSD avoidance and marital intimacy. Verbal aggression was also found via indirect effect of hyperarousal on marital intimacy. The results point to the importance of self-disclosure and verbal violence as interpersonal mechanisms for the relations between posttraumatic symptoms on marital intimacy of ex-POWs. 相似文献

The ability to isolate a single sound source among concurrent sources and reverberant energy is necessary for understanding the auditory world. The precedence effect describes a related experimental finding, that when presented with identical sounds from two locations with a short onset asynchrony (on the order of milliseconds), listeners report a single source with a location dominated by the lead sound. Single-cell recordings in multiple animal models have indicated that there are low-level mechanisms that may contribute to the precedence effect, yet psychophysical studies in humans have provided evidence that top-down cognitive processes have a great deal of influence on the perception of simulated echoes. In the present study, event-related potentials evoked by click pairs at and around listeners' echo thresholds indicate that perception of the lead and lag sound as individual sources elicits a negativity between 100 and 250 msec, previously termed the object-related negativity (ORN). Even for physically identical stimuli, the ORN is evident when listeners report hearing, as compared with not hearing, a second sound source. These results define a neural mechanism related to the conscious perception of multiple auditory objects. 相似文献

Research indicates the presence of an age-related pictorial processing deficit, for which the elderly may attempt to compensate
through the use of relational information. Cognitive asynchrony theory, a recent synthetic formulation which unites elements
of the generalized slowing hypothesis, environmental support theory, and the item-specific/relational information distinction,
has proven useful in a number of experiments in explaining these aspects of visual cognitive aging. The present experiments
tested this theoretical formulation under high processing demand conditions in both the relational and the pictorial/item-specific
realm. Young and older adults yielded a complex pattern of results consistent with the cognitive asynchrony synthesis of these
theoretical considerations. The present experiments add to the growing body of findings indicating that the cognitive subsystems
of memory decline at different rates, that the differences in cognitive processing between young and older adults tend to
be more quantitative than qualitative, and that the global age-related memory deficits of popular belief are in fact relatively
circumscribed and specific.

Child abuse reporting is mandatory for family therapists. Little is written regarding the impact of mandated reporting and its impact on the family therapy systemic processes. This paper reviews literature on the impact on therapy of mandated reporting, and shares the results of a study designed to assess the impact of mandated reporting on family therapist's attention to systemic issues. The study demonstrates that MFTs shift their focus when the question of a mandated report arises to the detriment of systemic considerations. The institutional split between investigation and treatment of child abuse is discussed. 相似文献

Extensive research has validated the standard functional analysis as a useful technology for identifying the function of problem behavior in individuals with developmental disabilities. The assessment of low‐rate problem behavior is one area that has yet to receive a significant amount of research. Some problem behaviors may occur at rates too low to be observed during a standard functional analysis, despite the fact that they may be highly destructive behaviors. The current study evaluated the effectiveness of initiating functional analysis sessions contingent on the occurrence of bursts of problem behavior for producing interpretable functional analysis results. While a standard functional analysis did not produce definitive results with respect to behavioral function, the ‘low‐rate’ functional analysis produced interpretable results for all three participants. Two of the three participants were available for the evaluation of treatments based on their functional analysis results. Function‐based treatments suppressed rates of problem behavior for both participants. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

Research exploring the underlying processes involved in successful mentorships has been lacking. In the present study, the roles of career motivation and career self-efficacy as explanatory factors were examined. Career motivation mediated the relationship between career mentoring and performance effectiveness. Contrary to prediction, only marginal support was received for career self-efficacy as a mediator between mentoring and indicators of career success. This research is unique in that it was the first to reveal linkages between mentoring, career self-efficacy, career motivation and protégé career success. Theoretical and practical implications of results are discussed. 相似文献
