Ingroup members who criticize their group face much less resistance than outgroup members who say the same thing (the intergroup sensitivity effect). In the context of intergroup conflict, however, it was predicted that treatment of ingroup critics would not be so generous. Muslim Indonesians read an extract from an interview in which the speaker criticized Muslims. The comments were attributed to either another Muslim or to a Christian. Before reading the criticism, half of the participants had read an article describing intense conflict between Muslims and Christians in Indonesia, whereas the other half read a neutral article. As predicted, negativity toward the ingroup critic and the ingroup critic's comments increased in the conflict salience condition, to the point that the intergroup sensitivity effect disappeared. However, conflict salience did not have an effect on attributions of motive or on agreement with the message. Implications for our understanding of “patriotic criticism” are discussed.

Results from two experiments revealed that prior experience with proactive interference (PI) diminished PI’s effects for both
young and older adults. Participants were given two rounds of experience, with different materials, in a situation that produced
PI. Comparisons with a control condition showed that the effects of PI on accuracy and on high-confidence intrusion errors
(false memory) were reduced on the second round, as compared with those on the first. Also, the ability of confidence to diagnose
accuracy of responding improved across rounds. Effects of prior experience with PI depended on feedback given at the time
of test (Experiment 1). At least in part, the diminishment of PI resulted from participants’ allocating more attention to
interference items during study in the second round than in the first (Experiment 2). Implications of the results for interpreting
age differences in PI and false memory are discussed. 相似文献

I describe a naive realist conception of perceptual knowledge, which faces a challenge from the idea that normal perceivers and brains-in-vats have equally justified perceptual beliefs. I defend the naive realist position from Nicholas Silins's recent version of this challenge. I argue that Silins's main objection fails, and that the naive realist understanding of perceptual knowledge can be reconciled with the idea that brains-in-vats have justified perceptual beliefs. 相似文献

Estrogen has been shown to have a strong modulatory influence on several types of cognition in both women and female rodents. Latent inhibition is a task in which pre-exposure to a neutral stimulus, such as a tone, later impedes the association of that stimulus with a particular consequence, such as a shock. Previous work from our lab demonstrates that high levels of estradiol (E2) administered to ovariectomized (OVX) female rats abolishes latent inhibition when compared to female rats with low levels of E2 or male rats. To determine if this E2-induced impairment also occurs with the natural variations of ovarian hormones during the estrous cycle, this behavior was investigated in cycling female rats. In addition, pre-pubertal male and female rats were also tested in this paradigm to determine if the previously described sex differences are activational or organizational in nature. In a latent inhibition paradigm using a tone and a shock, adult rats were conditioned during different points of the estrous cycle. Rats conditioned during proestrus, a period of high E2 levels, exhibited attenuated latent inhibition when compared to rats conditioned during estrus or metestrus, periods associated with low levels of E2. Moreover, this effect is not seen until puberty indicating it is dependent on the surge of hormones at puberty. This study confirms recent findings that high E2 interferes with latent inhibition and is the first to show this is based in the activational actions of hormones. 相似文献

We investigated the effects of divided attention during walking. Individuals were classified based on whether they were walking while talking on a cell phone, listening to an MP3 player, walking without any electronics or walking in a pair. In the first study, we found that cell phone users walked more slowly, changed directions more frequently, and were less likely to acknowledge other people than individuals in the other conditions. In the second study, we found that cell phone users were less likely to notice an unusual activity along their walking route (a unicycling clown). Cell phone usage may cause inattentional blindness even during a simple activity that should require few cognitive resources. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Social cognitive career theory (SCCT; Lent, Brown, & Hackett, 1994) seeks to explain the factors that shape educational and vocational interests and choices. We used meta-analytic path analyses to synthesize data (from 1981 to 2008) relevant to SCCT’s interest and choice hypotheses, organizing the literature according to Holland’s (1997) broad occupational themes. Sufficient data were available to test (a) a 6-variable version of the interest/choice model in the Realistic, Investigative, and Enterprising themes, and (b) a 4-variable version of the model in the Artistic, Social, and Conventional themes. Analyses of both model versions were generally consistent with theoretical expectations. However, tests of the 6-variable model indicated better support for representing the pathways from contextual variables to choice goals as being partially mediated by self-efficacy and outcome expectations rather than as producing only direct linkages to goals. We consider implications of the findings for theory, research, and SCCT-based interventions. 相似文献

Faces provide important information about identity, age, and even kinship. A previous study in chimpanzees reported greater similarity between the faces of mothers and sons compared with mothers and daughters, or unrelated individuals. This was interpreted as an inbreeding avoidance mechanism where females, the dispersing gender, should avoid mating with any male that resembles their mother. Alternatively, male faces may be more distinctive than female faces, biasing attention toward males. To test these hypotheses, chimpanzees and rhesus monkeys matched conspecifics' faces of unfamiliar mothers and fathers with their sons and daughters. Results showed no evidence of male distinctiveness, rather a cross-gender effect was found: chimpanzees were better matching moms with sons and fathers with daughters. Rhesus monkeys, however, showed an overwhelming bias toward male-distinctiveness. They were faster to learn male faces, performed better on father-offspring and parent-son trials, and were best matching fathers with sons. This suggests that for the rhesus monkey, inbreeding avoidance involves something other than facial phenotypic matching but that among chimpanzees, the visual recognition of facial similarities may play an important role. 相似文献

One goal of the present study was to determine how pre-exposure to a set of contextual cues affected subsequent reinforced inhibitory avoidance task performance using those cues (latent inhibition model). In addition, immunohistochemical assessment of the phosphorylated (activated) form of the extracellular signal-regulated kinase-1 and -2 (pERK1/2) was examined. Adult, male Long Evans rats were randomly assigned into either pre-exposure (PE) or different pre-exposure (DPE) groups. All rats received 3 days of contextual pre-exposure (same or different context as that used for reinforced training) and were trained, 24 h later, on an inhibitory avoidance task (with or without shock). Rats were euthanized 24 h after training; half with a retention test and half without. Behaviorally, the PE group showed reduced latencies to enter the dark/shock compartment during the retention test compared to the DPE group showing the latent inhibition phenomenon. Compared to the shocked and tested DPE group, the shocked and tested PE group showed fewer pERK1/2-ir neurons in the secondary motor cortex, the anterior cingulate, the pre- and infra-limbic cortices, and the central nucleus of the amygdala. These regions showed similar numbers of pERK1/2-labeled neurons when comparing the shocked and tested PE group with the nonshocked and tested PE group. This suggests the possibility that brain regions showing decreased pERK1/2 levels in association with attenuated inhibitory avoidance performance may be involved in different aspects of the memory retrieval process. 相似文献

Mediated exhibitionism is the phenomenon of amateur performers exposing their nude bodies on the Internet, and includes the
exchange of nude images by email, text message, webcam, electronic bulletin board, and other means of digital communication.
Although mediated exhibitionism has its foundation in live performance and traditional media forms, its potential as a means
for broadening the aesthetics of the body and offering a form of resistance to social control is magnified by the interactive
quality of the Internet. Conversely, new aesthetic ideals have been established and resistance to social control has been
challenged by the very technology which made resistance possible. A series of websites catering to mediated exhibitionism
were investigated. 相似文献
