Co-orientation by capuchin (Cebus apella) and squirrel (Saimiri sciureus) monkeys in response to familiar humans abruptly switching the direction of their visual attention was recorded. Co-orientation occurred more frequently overall in capuchins than squirrel monkeys. Capuchins showed a tendency to habituate within trials involving consecutive attention switches performed by 2 different people, whereas squirrel monkeys co-oriented more when the 2nd attention switch was by a 2nd actor. These results suggest variable attention-processing abilities in New World monkeys, including differences in summation of attention by others. 相似文献

Neurobiological dimensional models of personality aim to account for the structure of personality traits and disorders through links to neurotransmitter systems. Three such models are reviewed: those of Cloninger, Depue, and Siever. While these proposals have heuristic value, none of them has obtained strong empirical support. Our current understanding of neurobiology is insufficient to develop a model of personality on this basis. At this point, dimensions of personality should be derived from factor analysis rather than from neurobiological theories. 相似文献

The World Wide Web (WWW) poses a distinct capability to offer interventions tailored to the individual's characteristics. To fine tune the tailoring process, studies are needed to explore how Internet accessibility and usage are related to demographic, psychosocial, behavioral, and other health related characteristics. This study was based on a cross-sectional survey conducted on 2373 7th grade students of various ethnic groups in Southern California. Measures of Internet use included Internet use at school or at home, Email use, chat-room use, and Internet favoring. Logistic regressions were conducted to assess the associations between Internet uses with selected demographic, psychosocial, behavioral variables and self-reported health statuses. The proportion of students who could access the Internet at school or home was 90% and 40%, separately. Nearly all (99%) of the respondents could access the Internet either at school or at home. Higher SES and Asian ethnicity were associated with higher internet use. Among those who could access the Internet and after adjusting for the selected demographic and psychosocial variables, depression was positively related with chat-room use and using the Internet longer than 1 hour per day at home, and hostility was positively related with Internet favoring (All ORs = 1.2 for +1 STD, p < 0.05). Less parental monitoring and more unsupervised time were positively related to email use, chat-room use, and at home Internet use (ORs for +1 STD ranged from 1.2 to 2.0, all p < 0.05), but not related to at school Internet use. Substance use was positively related to email use, chat-room use, and at home Internet use (OR for "used" vs. "not used" ranged from 1.2 to 4.0, p < 0.05). Self-reported health problems were associated with higher levels of Internet use at home but lower levels of Internet use at school. More physical activity was related to more email use (OR = 1.3 for +1 STD), chat room use (OR = 1.2 for +1 STD), and at school ever Internet use (OR = 1.2 for +1 STD, all p < 0.05). Body mass index was not related to any of the Internet use-related measures. In this ethnically diverse sample of Southern California 7(th) grade students, 99% could access the Internet at school and/or at home. This suggests that the Internet is already a potential venue for large scale health communication studies. Adolescents with more psychosocial risk factors or detrimental health behaviors were more likely to use the Internet. Therefore, if used properly, Internet interventions could effectively address the high risk populations. Additional research is needed to gain a more complete understanding of the positive and negative consequences of Internet use among adolescents. 相似文献

Using an adaptation of the Attentional Networks Test, we investigated aspects of executive control in children with chromosome 22q11.2 deletion syndrome (DS22q11.2), a common but not well understood disorder that produces non-verbal cognitive deficits and a marked incidence of psychopathology. The data revealed that children with DS22q11.2 demonstrated greater difficulty than controls in locating and processing target items in the presence of distracters. Importantly, children with DS22q11.2 showed a deficit in the ability to monitor and adapt to stimulus conflict. These data provide evidence of inadequate conflict adaptation in children with DS22q11.2, a problem that is also present in schizophrenia. The findings of specific executive dysfunction in this group may provide a linkage between particular genetic abnormalities and the development of psychopathology. 相似文献

As people study more facts about a concept, it takes longer to retrieve a particular fact about that concept. This fan effect
(Anderson, 1974) has been attributed to competition among associations to a concept. Alternatively, the mental-model theory
(Radvansky & Zacks, 1991) suggests that the fan effect disappears when the related concepts are organized into a single mental
model. In the present study, attentional focus was manipulated to affect the mental model to be constructed. One group of
participants focused on the person dimension of personlocation pairs, whereas the other group focused on the location dimension.
The result showed that the fan effect with the focused dimension was greater than the fan effect with the nonfocused dimension,
which is contrary to the mental-model theory. The number of associations with a concept is indeed crucial during retrieval,
and the importance of the information seems to be accentuated with attentional focus. 相似文献

In the present experiments, we examined whether shifts of attention selectively interfere with the maintenance of both verbal
and spatial information in working memory and whether the interference produced by eye movements is due to the attention shifts
that accompany them. In Experiment 1, subjects performed either a spatial or a verbal working memory task, along with a secondary
task requiring fixation or a secondary task requiring shifts of attention. The results indicated that attention shifts interfered
with spatial, butnot with verbal, working memory, suggesting that the interference is specific to processes within the visuospatial sketchpad.
In Experiment 2, subjects performed a primary spatial working memory task, along with a secondary task requiring fixation,
an eye movement, or an attention shift executed in the absence of an eye movement. The results indicated that both eye movements
and attention shifts interfered with spatial working memory. Eye movements interfered to a much greater extent than shifts
of attention, however, suggesting that eye movements may contribute a unique source of interference, over and above the interference
produced by the attention shifts that accompany them. 相似文献

Within our current research climate, an emphasis has been placed on examining the cross-cultural applicability of psychological tools, and exploring their utility with people of different backgrounds. Within this line of investigation lies the risk of classifying people too broadly and masking important regional, tribal, or dialectical differences. This may be particularly potent among Native Americans, given the number of distinct indigenous entities. This study examined the psychometric characteristics of the Anxiety Sensitivity Index with a tribally homogeneous sample, as compared to previous tribally-heterogeneous and majority culture findings. Results suggested that data from a homogeneous Native American sample poorly fit factor solutions reported from heterogeneous Native American and Caucasian samples, and favored a unifactorial solution. Implications for assessment with Native American peoples are discussed. 相似文献

Scholars have argued that anger expressed by participants in mediation is counterproductive; yet, there is also reason to believe that expressions of anger can be productive. The authors tested these competing theories of emotion by using data from online mediation. Results show that expression of anger lowers the resolution rate in mediation and that this effect occurs in part because expressing anger generates an angry response by the other party. However, when respondents are especially vulnerable, expressions of anger by the filer do not hinder settlement. The authors also examined precursors to anger, such as value of dispute and reputation, and the degree to which a focus on dispute resolution is reciprocated. 相似文献
