ABSTRACT This article compared alcoholics and healthy controls on the Buschke Selective Reminding Task. Alcoholics demonstrated deficits in memory and learning when compared to healthy controls, even when controlling for age. Examination of the alcoholic sample initially showed that age predicted memory deficits; however, age was no longer a significant predictor once the number of years of heavy drinking was entered into the regression equation. Findings suggest a direct link or mechanism of action between alcohol use and memory impairments, above and beyond effects of age or education. 相似文献

ABSTRACT An increase in Stroop effects with age can be interpreted as reflecting age-related reductions in selective attention, cognitive slowing, or color-vision. In the present study, 88 younger adults performed a Stroop test with two color-sets, saturated and desaturated, to simulate an age-related decrease in color perception. This color manipulation with younger adults was sufficient to lead to an increase in Stroop effects that mimics age-effects. We conclude that age-related changes in color perception can contribute to the differences in Stroop effects observed in aging. Finally, we suggest that the clinical applications of Stroop take this factor into account. 相似文献

Abstract This study examined the role of social support in the relationship between work demand and psychological distress (GHQ 12) in correctional officers (N=419), a high stress occupational group. Work demands were positively associated with strain. There was no evidence that social support buffered the negative impact of work demands. Rather, consistent with most previous research findings, support showed direct benefits and these were discussed in the context of worker participation and control. The hypothesis that officers high in negative affectivity, as measured by trait anxiety would show greater reactivity to work demands was not supported. However, trait anxiety appeared to inflate the relationship between work stressors (work demand and work support) and psychological distress supporting recent suggestions that the role of trait anxiety in occupational stress should not be disregarded. Trait anxiety combined additively with work demand to predict individual differences in psychological distress, however social support moderated the impact of trait anxiety on strain. 相似文献

This article answers some of the criticisms and suggestions of the three commentaries. We showed, in agreement with Coyle, that (i) variability is indeed distinct from speed, (ii) they both additively reflect processing efficiency and (iii) that they differentially relate to WM and gf during development. In agreement with Kail, we showed that developmental intelligence and psychometric intelligence are (i) related but distinct, they additively contribute to school learning and (iii) their role varies with developmental phase. Finally, in agreement with Pascual-Leone, we proposed a number of higher level hidden constructs to account for the data patterns observed between empirical constructs, such as speed, variability, WM, and reasoning. 相似文献

In this study, the authors assess the effectiveness of education on the consistency of use of sensory rooms within a large mental health facility. Eleven staff and thirty-six clients received additional multimodal education in sensory strategies, the use of the sensory rooms on their assigned units, and the link between the rooms and clients' personal crisis intervention plans. Staff knowledge and room usage rates were analyzed pre- and post-training. The authors found statistically significant increases in staff knowledge post-training and increases in the use of the sensory rooms by study participants. The results support the effectiveness of training which uses hands-on, population-specific strategies. 相似文献

Priority decisions concerning maintenance or reconstruction of roads are made with the aim of road improvements with as little traffic disturbance and time loss as possible. However, it cannot be avoided that speed will be reduced and travel time increased during the time of construction. The present study shows how intuitive judgments of travel time losses are biased in a way similar to the times saving bias (Svenson, 2008), but not perfectly corresponding to that bias. This means that when speed is decreased from a slow speed <50 km/h, the time loss is underestimated and when speed is decreased from a high speed >80 km/h it is overestimated. Also, drivers, politicians and policy makers who do not make exact calculations are likely victims of the time loss bias. The time loss bias was weakened but not eliminated by a debiasing instruction including mathematical computations of travel times. When driving speed restrictions are implemented, in particular on fast motorways, it is necessary to consider and counteract the time loss bias and inform the public. This can be done, for example, in communications about travel time facts, by information in driver training and by mounting temporary road signs informing about the average travel time prolongation due to a road work. 相似文献

People often display excessive overconfidence when providing interval estimates, which biases decision‐making. Research has investigated the various measures to effectively reduce overconfidence, and the use of warnings has subsequently been considered to have a negligible reduction effect. We demonstrate with two separate experiments that the impact of warnings has to be reviewed in light of dynamic warning designs and cognitive warning process models. In experiment 1, in contrast to previous studies that only used unstructured warnings, we implement a warning incorporating some core elements of a structured warning design based on research in the fields of human factors and ergonomics. Furthermore, accounting for recent developments in the warning literature, we distinguish between static and dynamic warning design. In experiment 2, we examine the effectiveness of different elements of dynamic warnings. We show that a significantly higher reduction of overconfidence can be achieved by combining a structured warning content with a dynamic stimulus change to increase the warning's noticeability.

Pigeons prefer a positive discriminative (S+) stimulus that follows a less preferred event (a large number of required responses, a longer delay, or the absence of food) over a different S+ with a similar history of reinforcement that follows a more preferred event (a single required response, no delay, or food). We proposed that this phenomenon results from contrast (referred to as within-trial contrast) between the less preferred initial event and the signal for reinforcement. Delay reduction theory (Fantino, 1969) can account for these results by proposing that the less preferred initial event lengthens the duration of the trial, thereby allowing the S+ stimulus to occur later in the trial and thus become a better predictor of reinforcement. In the present experiments, we further explored this effect. In Experiment 1, we controlled for trial duration by using a fixed ratio response (30 pecks) as one initial event and the absence of pecking for the same duration as the other initial event (0 pecks). The pigeons showed a reliable preference for the positive stimulus that followed the least preferred initial event. In Experiment 2, we controlled for trial duration by using 30 pecks as one initial event and 1 peck followed by a delay that matched the duration of the preceding 30-peck trial. (Group Time Same). For Group Time Different, there was no delay following the 1-peck initial event. For Group Time Same, preference for the initial event negatively predicted the pigeons’ preference for the S+ stimulus that followed, supporting the contrast account. A somewhat greater preference for the discriminative stimulus that followed the least preferred initial event was found for Group Time Different suggesting that in addition to contrast, delay reduction also may play a small role. However, the greater initial-event preference found for Group Time Different suggests that contrast can account for the group difference as well. 相似文献

The aim of the present study was to evaluate whether a short parent-training program (PT) reduces risk factors related to development of childhood socio-emotional and behavior problems in a non-clinical community sample. Data were obtained from parents in a randomized controlled trial (RCT) on PT for children aged 2 to 8 years (N=186) at pre-intervention, post-intervention and one-year-follow up. There were significant differences in the changes in the two groups, with reductions in harsh parenting and child behavior problems, an enhancement of positive parenting and of the parents' sense of competence in the intervention group. The effects on parenting and parents' satisfaction all lasted through one-year follow up. Our findings suggests that a shortened version of a well-structured parenting intervention, The Incredible Years program, implemented in primary care at community level, reduces harsh parenting and strengthens positive parenting and parents' sense of competence, as reported by the parents. Issues related to a public health approach to promote positive parenting are discussed. 相似文献
