Contact research often manipulates the salience of group membership, with little consideration of how such manipulations affect feelings toward intergroup contact, and how contextual features may moderate its effects. We propose that feelings toward intergroup contact may not depend solely on the degree to which group membership appears to be salient, but on how references to group membership are interpreted in the intergroup context. Two experimental studies examined how references to group membership may be interpreted differently depending on their source (ingroup or outgroup) and the recipient (minority or majority), and how these interpretations predict feelings toward cross‐group interactions. In Study 1, references to group membership were interpreted more negatively from an outgroup source among majority participants, yet a reverse pattern was observed for minority participants. Similar effects were obtained in Study 2, yet participants tended to respond negatively when an outgroup member referred specifically to their group. Moreover, feelings about cross‐group interactions were predicted only (Study 1) and strongly (Study 2) by the degree to which outgroup members' references were interpreted negatively, beyond what was predicted by participants' general awareness of group membership. Implications of these findings for future research on contact and salience are discussed. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Early visual tagging: effects of target-distractor similarity and old age on search, subitization, and counting 总被引:1,自引:0,他引:1

Three experiments examined the effects of target-distractor (T-D) similarity and old age on the efficiency of searching for single targets and enumerating multiple targets. Experiment 1 showed that increasing T-D similarity selectively reduced the efficiency of enumerating small (< 4) numerosities (subitizing) but had little effect on enumerating larger numerosities (counting) or searching for a single target. Experiment 2 provided converging evidence using fixation frequencies and a finer range of T-D similarities. Experiment 3 showed that T-D similarity had a greater impact on older than on young adults, but only for subitizing. The data are discussed in terms of the mechanisms and architecture of early visual tagging, dissociable effects in search and enumeration, and the effects of aging on visual processing. 相似文献

Tone sequences with conflicting fundamental pitch and timbre changes are heard differently by musicians and nonmusicians 总被引:1,自引:0,他引:1

An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians. The AAT comprised different tone pairs, presented in both within-pair orders, in which overtone spectra rising in pitch were associated with missing fundamental frequencies (F0) falling in pitch, and vice versa. The F0 interval ranged from 2 to 9 semitones. The participants were instructed to decide whether the perceived pitch went up or down; no information was provided on the ambiguity of the stimuli. The majority of professionals classified the pitch changes according to F0, even at the smallest interval. By contrast, most nonmusicians classified according to the overtone spectra, except in the case of the largest interval. Amateurs ranged in between. A plausible explanation for the systematic group differences is that musical practice systematically shifted the perceptual focus from spectral toward missing-F0 pitch, although alternative explanations such as different genetic dispositions of musicians and nonmusicians cannot be ruled out.

The experiments reported here evaluated the hypothesis that an amphetamine-paired flavor elicits conditioned fear-arousal, whereas a lithium-paired flavor elicits conditioned nausea-disgust by examining the effect of prior flavor exposure on an acoustic startle reaction (ASR). Exposure to a lithium-paired flavor by intraoral infusion, either immediately prior to a startle session (Experiment 1) or during a startle session (Experiments 2 and 3), resulted in a blunted ASR. In contrast, intraoral infusion of an amphetamine-paired flavor resulted in a potentiated ASR. The blunted ASR produced by exposure to a lithium-paired flavor dramatically reversed to a potentiated ASR when rats were pretreated with the antiemetic drug ondansetron prior to the saccharin-lithium pairing (Experiment 3). The findings shed light on a mechanism by which rewarding drugs produce conditioned taste avoidance in rats. 相似文献

The review describes evidence-based psychological treatments (EBTs) for insomnia in older adults. Following coding procedures developed by the American Psychological Association's Committee on Science and Practice of the Society for Clinical Psychology, two treatments were found to meet EBT criteria: sleep restriction-sleep compression therapy and multicomponent cognitive-behavioral therapy. One additional treatment (stimulus control therapy) partially met criteria, but further corroborating studies are needed. At the present time, there is insufficient evidence to consider other psychological treatments, including cognitive therapy, relaxation, and sleep hygiene education, as stand-alone interventions beneficial for treating insomnia in older adults. Additional research is also needed to examine the efficacy of alternative-complementary therapies, such as bright light therapy, exercise, and massage. This review highlights potential problems with using coding procedures proposed in the EBT coding manual when reviewing the existing insomnia literature. In particular, the classification of older adults as persons age 60 and older and the lack of rigorous consideration of medical comorbidities warrant discussion in the future. 相似文献

This study examined how loss of contact with grandchildren due to parental separation or divorce, family feud, or a sudden event, such as relocation, affected the emotional well-being of grandparents (N = 442). Using data from the Longitudinal Study of Generations, the depressive symptoms of grandparents were tracked over 15 years. Growth curve analysis was used to compare grandparents who had lost contact with their grandchildren with those who had not and to examine preloss to postloss change in depressive symptoms. Grandparents who lost contact with their grandchildren experienced a steeper increase in depressive symptoms as they aged compared with other grandparents. Depressive symptoms of grandparents who lost contact because of a sudden event increased up to 3 years following the loss but returned to equilibrium thereafter. The authors conclude that grandparents who lost contact with their grandchildren experienced a negative impact on their emotional health. 相似文献

Using symbolic interaction, we developed a research model that proposed adolescent perceptions of parental support and psychological
control would be related to adolescent depressed mood directly and indirectly through self-esteem. We tested the model using
self-report questionnaire data from 161 adolescents living with both of their biological parents. To examine possible gender
of adolescent differences, we tested two multigroup models separately for adolescents’ perceptions of mothers’ and fathers’
parental behaviors. Both the fathers’ and mothers’ models yielded (a) direct paths from self-esteem to depressed mood (for
boys and girls), psychological control to depressed mood (for boys) and (b) an indirect path from support to self-esteem to
depressed mood (for girls and boys) and an indirect path from psychological control to self-esteem to depressed mood (for
girls). In addition, in the fathers’ model a significant direct path was found between fathers’ support and depressed mood
(for girls). 相似文献

We surveyed 191 Southwest Ohio foster parents regarding their involvement in authoritative parenting and interest for additional
parenting education. Our results showed that most respondents reported using an authoritative parenting style and were interested
in receiving future training. Involvement in authoritative parenting differed significantly based on level of education and
number of years as a foster parent. Foster parents with a college degree or higher were significantly more involved in authoritative
parenting than foster parents with a high school diploma or less. Those who had been a foster parent for greater than five
years were significantly more likely than those who been a foster parent for five years or less to use authoritative parenting
and desire future training in authoritative parenting. 相似文献
