Attention network theory suggests that there are three separate neural networks that execute the discrete functions of alerting, orienting, and executive attention. Previous research on the influence of mood on attention has shown subtle and inconsistent results. The attention network theory may aid in clarifying the influence of mood on attention. The present study investigated the influence of mood on attentional networks in a normal population. Participants performed the Attention Network Test (ANT), which provides functional measures of alerting, orienting, and executive attention. Positive or negative mood was induced by listening to music with a positive or negative valence, respectively; neutral mood was induced by reading a collection of basic facts about China. The results revealed that negative mood led to a significantly higher alerting efficiency relative to other moods, while there were no significant mood effects on orienting or executive attention efficiency. According to the algorithm underlying the ANT, the higher alerting efficiency in the negative mood condition can be attributed to relatively greater benefits of cueing effects. The findings are discussed in the context of the noradrenergic system and of evolutionary significance. Specifically, the increase in the alerting function during negative mood states may be due to the modulation effect of negative mood on the noradrenergic system, and/or to the survival benefit resulting from an increase in automatic vigilance towards negative information. The current results suggest that as the influence of negative mood on attention appears to specifically consist in an enhanced alerting function, it may not be found in studies where the three attentional networks are not dissociated. 相似文献

The Analytic Hierarchy Process (AHP) ratio-scaling approach is re-examined in view of the recent developments in mathematical psychology based on the so-called separable representations. The study highlights the distortions in the estimates based on the maximum eigenvalue method used in the AHP distinguishing the contributions due to random noises from the effects due to the nonlinearity of the subjective weighting function of separable representations. The analysis is based on the second order expansion of the Perron eigenvector and Perron eigenvalue in reciprocally symmetric matrices with perturbations. The asymptotic distributions of the Perron eigenvector and Perron eigenvalue are derived and related to the eigenvalue-based index of cardinal consistency used in the AHP. The results show the limits of using the latter index as a rule to assess the quality of the estimates of a ratio scale. The AHP method to estimate the ratio scales is compared with the classical ratio magnitude approach used in psychophysics. 相似文献

The current study investigated the stability of peer victimization and the impact of the timing and duration of victimization on psychological and academic outcomes for boys and girls on a sample of 863 middle school students. Results demonstrated strong support for the onset hypothesis and concurrent effects of maladjustment in anxiety, depression, self-esteem, poor school attitude, GPA, and attendance. Support for the cessation hypothesis was mixed, depending on the outcome and gender: boys demonstrated recovery from internalizing distress, whereas girls demonstrated residual effects, even after the cessation of victimization. Girls also demonstrated residual effects of victimization on grades, and both boys and girls evidenced residual effects of victimization on attendance. Regarding duration of victimization, there was strong support for the life-events model of stress and coping across almost all outcomes, suggesting that even temporary experiences of victimization could have a negative impact on psychological and academic outcomes. Overall, results demonstrated the importance of considering the timing and duration of victimization in understanding the risks and damaging effects of victimization. The results from this study also highlight both the need and the potential to intervene during early adolescence when peer relationships are taking on increasing importance, as well as the importance of helping students regain social-emotional and academic functioning, even after victimization ceases. 相似文献

This article describes the results of three studies designed to understand better the journal operations, publishing practices, and impact of school psychology journals in recent years. The first study presents the results of a survey focusing on journal operations and peer-review practices that was completed by 61 journal editors of school psychology and aligned journals. The second study presents the results of review and classification of all articles appearing in one volume year for nine school psychology journals (i.e., The California School Psychologist, Canadian Journal of School Psychology, Journal of Applied School Psychology, Journal of School Psychology, Psychology in the Schools, School Psychology Forum, School Psychology International, School Psychology Quarterly, and School Psychology Review). The third study employed multilevel modeling to investigate differences in the longitudinal trends of impact factor data for five school psychology journals listed in the Web of Science (i.e., Journal of School Psychology, Psychology in the Schools, School Psychology International, School Psychology Quarterly, and School Psychology Review). The article addresses implications for authors, editors, and journal editorial teams as well as the status and impact of school psychology journals. 相似文献

Simple and complex span tasks are widely thought to measure related but separable memory constructs. Recently, however, research
has demonstrated that simple and complex span tasks may tap, in part, the same construct because both similarly predict performance
on measures of fluid intelligence (Gf) when the number of items retrieved from secondary memory (SM) is equated (Unsworth
& Engle, Journal of Memory and Language 54:68–80 2006). Two studies (n = 105 and n = 152) evaluated whether retrieval from SM is influenced by individual differences in the use of encoding strategies during
span tasks. Results demonstrated that, after equating the number of items retrieved from SM, simple and complex span performance
similarly predicted Gf performance, but rates of effective strategy use did not mediate the span-Gf relationships. Moreover,
at the level of individual differences, effective strategy use was more highly related to complex span performance than to
simple span performance. Thus, even though individual differences in effective strategy use influenced span performance on
trials that required retrieval from SM, strategic behavior at encoding cannot account for the similarities between simple
and complex span tasks. 相似文献

The purpose of this research was to test whether delay between a mug book task and a lineup task moderates a simple mug shot exposure effect. Following the witnessing of a simulated theft, participants searched either a small, large or no mug book. Participants then viewed a lineup that contained either the perpetrator or an innocent replacement; the lineup occurred either immediately after viewing the mug book or 48 hours later. There were fewer suspect identifications and more lineup rejections in the mug book conditions than the no mug book control; this was explained in terms of the criterion for making choices carrying over from the mug book to the lineup. There was qualified support for delay moderating the mug book exposure effect. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Recent evidence suggests that the degree of interference in dual-task situations depends crucially on the pairings of input-
and output modalities of the two component tasks with increased dual-task costs for modality incompatible (i.e., visual–vocal
and auditory–manual) compared to modality compatible (i.e., visual–manual and auditory–vocal) dual tasks. These effects of
modality pairings in dual tasks have been related to the overlap of non-preferred processing pathways in modality incompatible
tasks. Until now, modality compatibility has not yet been related to other sources of interference in a dual-task context,
such as stimulus–response (S–R) compatibility or crosstalk. In the present study, we conducted two experiments using the paradigm
of the psychological refractory period (PRP) to test the effects of S–R compatibility and crosstalk on the effects of modality
compatibility in temporally overlapping task situations. Experiment 1 revealed an overadditive interaction between stimulus
onset asynchrony and modality compatibility for tasks with S–R compatible mappings, indicating that modality compatibility
effects are present in different task situations, even when S–R mappings are otherwise compatible. In Experiment 2, we aimed
at pinpointing the boundaries of the effects of modality compatibility in dual-task situations. We showed that additional
sources of dual-task interference in a modality compatible dual task could overwrite the pronounced PRP effect previously
shown for modality incompatible tasks. Taken together, these data provide new evidence that the specific types of stimulus–response
modality pairings are an additional factor that might interact with other sources of interference in dual-task situations. 相似文献

Previous research posited that butch lesbians are physiologically similar to heterosexual men, and by implication, femme lesbians physiologically resemble heterosexual women. The current study sought to compare partner preferences among butch and femme lesbians, as well as heterosexual women and men. More than 600 personal advertisements from newspapers and websites across the United States were examined. Forty-seven percent of advertisers indicated their race; of those, 60% were White and 29% Black. Testing competing hypotheses, support was found for a unique constellation of partner preferences for lesbians that is not fully explained by social exchange theory or evolutionary psychology theories. 相似文献

The authors proposed a novel explanation for cultural differences in ingroup favoritism (dialecticism) and tested this hypothesis across cultures/ethnicities, domains, and levels of analysis (explicit vs. implicit, cognitive vs. affective). Dialecticism refers to the cognitive tendency to tolerate contradiction and is more frequently found among East Asian than North American cultures. In Study 1, Chinese were significantly less positive, compared to European Americans, in their explicit judgments of family members. Study 2 investigated ingroup attitudes among Chinese, Latinos, and European Americans. Only Chinese participants showed significant in-group derogation, relative to the other groups, and dialecticism (Dialectical Self Scale) was associated with participants' in group attitudes. Study 3 manipulated dialectical versus linear lay beliefs; participants primed with dialecticism showed more negative, explicit ingroup attitudes. Although ingroup disfavoring tendencies were more prevalent among Chinese across studies, they may be a reflection of one's culturally based lay beliefs rather than deep-rooted negative feelings toward one's ingroup. 相似文献

We tested the feasibility of parents recording social interactions with their infants using inexpensive camcorders, as a potential method of effective, convenient, and economical large scale data gathering on social communication. Participants were asked to record two short video clips during either play or a mealtime, and return the data. Sixty-five video clips (32 pairs) were returned by 33 families, comprising 8.5% of families contacted, 44.6% of respondents and 51.6% of those sent a camcorder, and the general visual and sound quality of the data was assessed.Audio and video quality were adequate for analysis in 85% of clips and several social behaviours, including social engagement and contingent responsiveness, could be assessed in 97% of clips. We examined two quantifiable social behaviours quantitatively in both adults and infants: gaze direction and duration, and vocalization occurrence and duration. It proved difficult for most observers to obtain a simultaneous clear view of the parents and infant's face.Video clips obtained by parents are informative and usable for analysis. Further work is required to establish the acceptability of this technique in longitudinal studies of child development and to maximize the return of usable data. 相似文献
