Although the existence of implicit motor learning is now widely accepted, the findings concerning perceptual implicit learning are ambiguous. Some researchers have observed perceptual learning whereas other authors have not. The review of the literature provides different reasons to explain this ambiguous picture, such as differences in the underlying learning processes, selective attention, or differences in the difficulty to express this knowledge. In three experiments, we investigated implicit visual learning within the original serial reaction time task. We used different response devices (keyboard vs. mouse) in order to manipulate selective attention towards response dimensions. Results showed that visual and motor sequence learning differed in terms of RT-benefits, but not in terms of the amount of knowledge assessed after training. Furthermore, visual sequence learning was modulated by selective attention. However, the findings of all three experiments suggest that selective attention did not alter implicit but rather explicit learning processes. 相似文献

ABSTRACTIn spatial compatibility tasks, when the spatial location of a stimulus is irrelevant it nevertheless interferes when a response is required in a different spatial location. For example, response with a left key-press is slowed when the stimulus is presented to the right as compared to the left side of a computer screen. However, in some conditions this interference effect is not detected in reaction time (RT) measures. It is typically assumed that the lack of effect means the irrelevant spatial code was not analysed or that the information rapidly decayed before response. However, we show that even in conditions where there appears to be no spatial interference when measuring RTs, effects can nevertheless be detected after response when recording facial electromyography responses. This dissociation between two measures highlights the importance of diverging methods to investigate visuomotor processes as conclusions based on only one measure can be misleading. 相似文献

We review the recent research literature on pro-criminal attitudes (PCAs) as a causal factor of recidivism with a focus on studies on the effectiveness of offender treatment programs targeting PCAs to prevent recidivism. The main conclusions that can be derived from the literature are: (1) the evidence supports the hypothesis that PCAs are related to reoffending; (2) most investigated offender treatment programs tend to reduce PCAs, although the general lack of adequate control group designs does not rule out alternative explanations for this reduction; and (3) there is no conclusive empirical evidence that intervention programs designed to reduce PCAs are effective in reducing recidivism. Empirical research in this area lacks the theoretical and methodological rigor to test causal models of the influence of treatment on reducing PCAs, and effects of PCAs on recidivism. Limitations of the empirical evidence are related to inadequate research designs and/or suboptimal data analysis strategies. Recommendations concerning optimized research designs and data analysis strategies that are likely to provide more conclusive evidence on the relation of PCAs, PCA treatment, and recidivism are given. 相似文献

The question of when other people’s bad acts belong on our moral ledger arises in a number of different scenarios. Each scenario has received some philosophical attention, but no one has noted the structural similarities of these various scenarios or the implications of a proposed approach to one for how the others should be approached. That is the ambition of this article. In it, seemingly disparate moral phenomena—blunt rules, preemptive restrictions, moral blackmail, complicity, retreat and proportional response, and the duty to rescue from a peril one has caused—are shown to have similar structures and thus to require similar moral approaches. 相似文献

Various authors have referred to an association between neglect and non‐spatial components of attention. It has been suggested that an increase in attentional load could exacerbate neglect symptoms and reveal subtle, well‐compensated neglect. In the present study, 21 RH and 22 LH subacute stroke patients and 20 controls performed a computerized single‐detection task (CVRT) and a dual task (CVRT‐D) combining the detection task with a driving simulation task. Omissions, reaction times (RTs) and RT asymmetries were analysed to investigate the influence of increasing attentional load on neglect symptoms. RT asymmetries were most pronounced in RH patients. Although a clear increase in RT asymmetries between CVRT and CVRT‐D was observed, the amount of increase did not differ between both patient groups. Within both patient groups, correlations between RT asymmetries and ipsilesional RTs as a measure of general attention were significant in the single task but not in the dual task, indicating that increased attentional load may result in different degrees of lateralized and general attentional problems. Half of the patients with neglect on the BIT (Behavioural Inattention Test) showed increased RT asymmetries from CVRT to CVRT‐D. Moreover, two LH and RH patients without neglect symptoms on the BIT and CVRT showed distinctively increased asymmetries in the CVRT‐D, fostering the idea of an emergence of subtle neglect under increased attentional load. Dual‐task performance may draw attention towards patients who, without obvious signs of neglect, may show visuospatial attention deficits in complex situations. 相似文献

The paper raises some difficulties for the typical motivations behind set reductionism, the view that sets are reducible to entities identified independently of set theory. 相似文献

This study was designed to examine the effects of playing the online game World of Warcraft (WoW) on adolescents' social competence and loneliness, and to investigate the underlying mechanisms of the Internet‐affected social compensation hypothesis. The hypothesis states that being online affects adolescents' social competence as a result of a variety of communication partners and identity experiments online. A survey was conducted among 790 high school students. There appeared to be no direct effect between playing WoW and adolescents' social competence and loneliness. We did find an indirect effect via variety of communication partners. Adolescents who play WoW vary more in their communication partners, leading to an increase of social competence and a decrease of loneliness. 相似文献

The authors examined the relationship between newborn neurobehavioral profiles and the characteristics of early mother-infant interaction in Nagasaki, Japan. The authors administered the Brazelton Neonatal Behavioral Assessment Scale (NBAS; T. B. Brazelton &; J. K. Nugent, 1995) in the newborn period and the Nursing Child Assessment Teaching Scale at 1 month (NCATS; G. Sumner &; A. Spietz, 1994). They administered the Perceived Stress Scale (S. Cohen, T. Kamarck, &; R. Mermelstein, 1983) as an index of maternal stress experienced over the past month. Lower irritability, higher stability in skin coloration, and lower tremulousness in the neonatal period were correlated with higher levels of maternal nurturing behaviors at 1 month. Birth weight and 2 NBAS range-of-state items (peak of excitement, irritability) predicted 31% of the variance in NCATS caregiver subscale score. The NBAS autonomic stability items (tremulousness, startles, lability of skin color) predicted 31% of the variance in the NCATS child subscale score. Perceived stress and maternal sociodemographic variables (education, income, age, parity) were not associated with child, caregiver, and total scores on the NCATS. The results suggested that lack of autonomic stability in Japanese neonates might serve as an early indicator of infant frailty, negative behavioral cues, and decreased maternal responsiveness. 相似文献

The Flynn effect (FE; i.e., increase in mean IQ scores over time) is commonly viewed as reflecting population shifts in intelligence, despite the fact that most FE studies have not investigated the assumption of score comparability. Consequently, the extent to which these mean differences in IQ scores reflect population shifts in cognitive abilities versus changes in the instruments used to measure these abilities is unclear. In this study, we used modern psychometric tools to examine the FE. First, we equated raw scores for each common subtest to be on the same scale across instruments. This enabled the combination of scores from all three instruments into one of 13 age groups before converting raw scores into Z scores. Second, using age-based standardized scores for standardization samples, we examined measurement invariance across the second (revised), third, and fourth editions of the Wechsler Adult Intelligence Scale. Results indicate that while scores were equivalent across the third and fourth editions, they were not equivalent across the second and third editions. Results suggest that there is some evidence for an increase in intelligence, but also call into question many published FE findings as presuming the instruments' scores are invariant when this assumption is not warranted. 相似文献
