The acute effects of alcohol on cognitive processing of expectancy violations were investigated using event-related brain potentials and a cued recall task to index attentional and working memory processes associated with inconsistency resolution. As predicted, expectancy-violating behaviors elicited larger late positive potentials (LPP) and were recalled better than expectancy-consistent behaviors. These effects were moderated by alcohol and the valence of initial expectancies. For placebo group participants, positive targets performing negative behaviors elicited the largest LPP responses and were recalled best. For those in the alcohol groups, negative targets behaving positively elicited the largest LPP and recall responses. These findings suggest that alcohol does not globally impair working memory processes in person perception but instead changes the nature of valenced information processing. Findings are discussed in the context of alcohol's effects on working memory processes, reward sensitivity, and the prefrontal cortical structures thought to mediate them. 相似文献

Prevalence of Attention-Deficit/Hyperactivity Disorder Symptoms in 4- to 17-Year-Old Children in the General Population 总被引:7,自引:0,他引:7

The purposes of this study were (a) to estimate the prevalence of Attention-Deficit/Hyperactivity Disorder (AD/HD) symptoms in the general preschool and school population; and (b) to analyze the influence of gender, age, and socioeconomic status (SES) variables on AD/HD symptoms. Out of the 80,000 preschool and schoolchildren living in Manizales, Colombia, a random sample of 540 children was selected. Two gender, three age (4- to 5-year olds, 6- to 11 -year olds, and 12- to 17-year olds), and three SES (low, middle, and high) groups were used. The 18 DSM-IV symptoms corresponding to AD/HD Criterion A were assessed on a scale of 0 (never) to 3 (almost always). All three demographic variables established statistically significant differences: AD/HD symptoms were more frequent in 6-to 11-year-old, low-SES, male participants. DSM-IV Criterion A for AD/HD was fulfilled by 19.8% of the boys and 12.3% of the girls. However, this difference was marginally significant only in the AD/HD Subtype I: Combined. It was concluded that demographic variables are significant correlates of the AD/HD diagnosis. The prevalence found in this study was higher than usually reported, even though only the symptomatic DSM-IV AD/HD criterion was analyzed. We failed to confirm the assumed AD/HD gender ratio. 相似文献

A central tenet of rational emotive behaviour therapy (REBT) has always been that irrational beliefs which express demands through absolutistic shoulds, musts or oughts are the basic cause of emotional disturbance. This premise is characteristic of Ellis' theory but is not always supported by other REBT writers or other writers within the cognitive therapy field. This paper reviews a range of research findings which appear to call into question Ellis' tenet of the primacy of the shoulds and which, in turn, raise theoretical and methodological difficulties in the measurement of beliefs. This along with the current theoretical debate regarding irrational belief processes may preclude the possibility of testing the proposition that demandingness is the primary irrational or dysfunctional belief. 相似文献

Surface maps of brain activity can be obtained with electrophysiological and optical recordings. However, there are no established methods for determining the reliability of maps of brain activity across subject groups or across tasks within the same subject. In this paper, we use bootstrapping to establish the reliability of the locations of maxima in maps of surface brain activity of individual subjects obtained with ERP and optical (EROS) recordings and report sample analyses for two data sets. Bootstrapping is a nonparametric method for estimating statistical accuracy from the data in a single sample. The distribution of the statistic of interest is estimated by constructing “bootstrap samples” from a pool of all available cases (with replacement). Many “bootstrap replications” are obtained by calculating the statistic of interest for each sample. In the case of brain activity, many (e.g., 10,000) amplitude distributions can be derived from the data of an individual subject. Frequency counts are then computed for each recording location to establish how many times that location corresponds to a maximum. The value obtained in this fashion represents an estimate of the reliability of the observation. 相似文献

It has been well documented that people with negative emotional reactions to sex (e.g., "erotophobia,""sex guilt") have less knowledge about contraception than do people with more positive reactions. Recent research has suggested that this deficit is not related to an inability to learn the information, but is due at least in part to the fact that erotophobics actively avoid contraceptive information. The current study was designed to examine the role of erotophobia and high self-esteem in resistance to learning sexual information. More specifically it compared pretest and posttest knowledge of contraception and AIDS in high self-esteem and low self-esteem, erotophobia, and erotophilic women in a university class on human reproduction. As expected, high self-esteem erotophobic subjects were less Likely than other subjects to retain contraceptive and AIDS information presented in the class. Implications of this study for contraceptive and AIDS educational strategies are discussed. 相似文献

Combining information across different sensory modalities is of critical importance for the animal's survival and a core feature of human's everyday life. In adulthood, sensory information is often integrated in a statistically optimal fashion, so that the combined estimates of two or more senses are more reliable than the best single one. Several studies have shown that young children use one sense to calibrate the others, which results in unisensory dominance and undermines their optimal multisensory integration abilities. In this study we trained children aged 4–5 years with action‐like mini games, to determine whether it could improve their multisensory as well as their visuo‐spatial skills. Multisensory integration abilities were assessed using a visuo‐haptic size discrimination task, while visuo‐spatial attention skills were investigated using a multiple object tracking task (MOT). We found that 2‐weeks training were sufficient to observe both optimal multisensory integration and visuo‐spatial enhancements selectively in the group trained with action‐like mini games. This plastic change persisted up to 3 months, as assessed in a follow‐up. Our novel findings reveal that abilities that are commonly known to emerge in late childhood can be promoted in younger children through action‐like mini games and have long‐lasting effects. Our data have clinical implications, in that they suggest that specific trainings could potentially help children with multisensory integration deficits. 相似文献

Based on an exploratory study of 29 semi-structured interviews followed by a grounded theory analysis, this research explores the circulation of local products and brands enacted by bi-residential consumers with geographically dispersed networks across two places. The results show that two new consumption systems are emerging at the frontier between conventional and collaborative consumption: bi-residential and delegated consumption. In these two consumption systems, the bi-residential consumer mediates the relationship between the retailer and the final consumer, thus informally extending the retailer's downstream value chain. Bi-residential and delegated systems partly overlap but also differ from conventional or collaborative consumption systems in two ways: (a) they are linked in a modelized process sustained by the perception of ‘access’ and the ‘logistic role’ of the bi-residential consumer; (b) they are embedded in a hybrid exchange system intertwining gift-giving and monetary exchange. These consumption systems occur at the interstice between conventional and collaborative consumption. Local retailers and brands could benefit from knowledge in this area with a view to opening up new opportunities in value co-creation with bi-residential consumers. 相似文献

Contextual guidance of eye movements and attention in real-world scenes: the role of global features in object search 总被引:2,自引:0,他引:2
Many experiments have shown that the human visual system makes extensive use of contextual information for facilitating object search in natural scenes. However, the question of how to formally model contextual influences is still open. On the basis of a Bayesian framework, the authors present an original approach of attentional guidance by global scene context. The model comprises 2 parallel pathways; one pathway computes local features (saliency) and the other computes global (scene-centered) features. The contextual guidance model of attention combines bottom-up saliency, scene context, and top-down mechanisms at an early stage of visual processing and predicts the image regions likely to be fixated by human observers performing natural search tasks in real-world scenes. 相似文献
