Recent data indicate that under a specific posthypnotic suggestion to circumvent reading, highly suggestible subjects successfully eliminated the Stroop interference effect. The present study examined whether an optical explanation (e.g., visual blurring or looking away) could account for this finding. Using cyclopentolate hydrochloride eye drops to pharmacologically prevent visual accommodation in all subjects, behavioral Stroop data were collected from six highly hypnotizables and six less suggestibles using an optical setup that guaranteed either sharply focused or blurred vision. The highly suggestibles performed the Stroop task when naturally vigilant, under posthypnotic suggestion not to read, and while visually blurred; the less suggestibles ran naturally vigilant, while looking away, and while visually blurred. Although visual accommodation was precluded for all subjects, posthypnotic suggestion effectively eliminated Stroop interference and was comparable to looking away in controls. These data strengthen the view that Stroop interference is neither robust nor inevitable and support the hypothesis that posthypnotic suggestion may exert a top-down influence on neural processing. 相似文献

The effects of age on cue learning, spatial reference memory, and strategy preference were assessed in B6 × SJL F1 mice by using the Morris water maze. This mouse strain is of particular interest because it is the background strain for a common transgenic model of Alzheimer's disease, the Tg2576 mouse, which develops plaques and other neurobiological markers of pathology beginning at 8 mo and increasing in severity with advanced age. In the current study, 12- and 23-mo-old C57B6 × SJL F1 mice were serially trained in cue and place versions of the Morris water maze task. At the completion of training, mice received a strategy probe test in which place (hidden) and cue (visible) strategies were in competition. Cue and spatial learning ability was maintained between 12 and 23 mo of age; however, on the strategy preference probe test, the 23-mo-old mice exhibited a significant bias toward the selection of a cue strategy. There was no relationship between strategy preference in the probe test and spatial learning ability, but the 23-mo-old mice did exhibit a strong trend toward shorter latencies during visible platform training, possibly reflecting the enhanced function of striatal-based neural systems in aging. These data demonstrate that 23-mo-old C57B6 × SJL F1 mice are capable of effective place learning, but if a place strategy is pitted against the use of a cue strategy, the use of a cue strategy predominates in the aged mice. The strategy preference observed here may reflect an emergence of differential processing in underlying brain circuitry with age in the B6 × SJL F1 mouse strain. 相似文献

Despite considerable speculation in the research literature regarding the complementarity of functional lateralization of prosodic and linguistic processes in the normal intact brain, few studies have directly addressed this issue. In the present study, behavioral laterality indices of emotional prosodic and traditional linguistic speech functions were obtained for a sample of healthy young adults, using the dichotic listening method. After screening for adequate emotional prosody and linguistic recognition abilities, participants completed the Fused Rhymed Words Test (FRWT; Wexler & Halwes, 1983) and the Dichotic Emotion Recognition Test (DERT; McNeely & Netley, 1998). Examination of the difference in ear asymmetries for these measures within individuals revealed a complementary pattern in 78% of the sample. However, the correlation between laterality quotients for the FRWT and DERT was near zero, supporting Bryden's model of "statistical" complementarity (e.g., Bryden, 1990). 相似文献

The purpose of this research was to develop a standardized content analytic measure of cognitive bias as conceptualized in Beck's (1987) cognitive theory of depression. In a pilot study it was determined that a written stimulus format was preferable to an audiotaped stimulus format with respect to comprehensibility. Valence and expectancy ratings collected in this pilot study also served as the basis for selection of items for the final measure, balancing positive and negative, expected and unexpected events. In study 2 open-ended written responses to questions about the main cause of each event, and the justifications for these attributions, were coded for indices of bias, defined (as in Cook & Peterson, 1986) as justifications that fail to cite covariation of the ascribed cause with the effect. Cognitive bias scores in Study 2 showed internal consistency (positive item-remainder correlations) and high interrater reliability. As predicted, justifications of attributions for expected events were more biased and less rational than were justifications of attributions for unexpected events. 相似文献

In this essay we argue that infant temperament, defined as behavioral styles that appear early in life as a direct result of neurobiological factors, plays a significant role in the development and expression of social behavior. Temperament may be studied using a typological or dimensional approach and the relations between early temperament and later behavior can be examined in terms of homotypic or heterotypic continuity. The implication of each of these approaches for understanding the influence of infant temperament on social development is examined. As well, utilizing data from our laboratory, we suggest that under certain circumstances one can predict social behavior by identifying two temperament types in infancy. These types are high reactive/high negative infants and high reactive/high positive infants. A significant proportion of the high reactive/high negative infants display behavioral inhibition and social reticence through the preschool years, whereas a significant proportion of the high reactive/high positive infants display exuberance and positive social interaction through the preschool period. 相似文献

The authors examined perfectionism and its association with perceived stress, coping processes, and burnout in a sample of 298 practicing school counselors. Latent profile analysis based on measures of perfectionism supported a 3‐class model made up of adaptive perfectionists, maladaptive perfectionists, and nonperfectionists. Among these groups, the authors found significant differences in perceived stress, coping processes, and burnout. Implications for the school counseling profession are discussed. 相似文献

This study assessed the performance of the PC-PTSD in diagnosing postdeployment posttraumatic stress disorder (PTSD) in a cohort of Air Force Medical Services personnel (N = 18,530). The prevalence of PTSD in the cohort was 5.18% based on medical record data. The area under the receiver operating characteristic curve was 0.69, indicating poor classification accuracy. Sensitivity was 47.55%, specificity was 90.68%, positive predictive value was 21.79%, and negative predictive value was 96.94%. The positive and negative likelihood ratios were 5.10 and 0.58, respectively. Several risk factors were found to be associated with a diagnosis of postdeployment PTSD: being a nurse, being enlisted in the medical service career field, being enlisted in the mental health service career field, those over age 30, being a member of the Active Duty service component, and having one’s first deployment be to Iraq. Being an officer was found to be a protective characteristic. These factors could potentially improve screening for PTSD among Air Force healthcare personnel. 相似文献

School counselors play a crucial role in the prevention, assessment, treatment, and overall management of eating‐related problems among children and adolescents. This article provides a framework for conceptualizing these difficulties on a continuum of severity and includes recommendations at each level for intervention and consultation. Collaboration with other professionals is encouraged when confronted with these multifaceted issues. Efforts by school counselors are vital to prevention and recovery from eating disorders. 相似文献

The identification performance of children (5 to 6 years, n = 180; 9 to 10 years, n = 180) and adults (n = 180) was examined using three types of video lineup procedures: simultaneous, sequential and elimination. Participants viewed a videotaped staged theft and then attempted to identify the culprit from a target‐present or target‐absent video lineup. Correct identifications in simultaneous and elimination video lineups did not differ as a function of age. The sequential video lineup was associated with a reduction in correct identifications for both child groups compared with adults. With respect to the target‐absent lineup condition, the video elimination lineup was associated with an increase in correct rejection rates for adult witnesses. Age was also significantly associated with accuracy. Differences in correct rejection rates were observed between adults and children and also between the two child groups. Implications and future directions are discussed. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献
