Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are commonly comorbid, share genetic liability, and often exhibit overlapping cognitive impairments. Clarification of shared and distinct cognitive effects while considering comorbid symptoms across disorders has been lacking. In the current study, children ages 7–15 years assigned to three diagnostic groups:ADHD (n?=?509), ASD (n?=?97), and controls (n?=?301) completed measures spanning the cognitive domains of attention/arousal, working memory, set-shifting, inhibition, and response variability. Specific processes contributing to response variability were examined using a drift diffusion model, which separately quantified drift rate (i.e., efficiency of information processing), boundary separation (i.e., speed-accuracy trade-offs), and non-decision time. Children with ADHD and ASD were impaired on attention/arousal, processing speed, working memory, and response inhibition, but did not differ from controls on measures of delayed reward discounting, set-shifting, or interference control. Overall, impairments in the ASD group were not attributable to ADHD symptoms using either continuous symptom measures or latent categorical grouping approaches. Similarly, impairments in the ADHD group were not attributable to ASD symptoms. When specific RT parameters were considered, children with ADHD and ASD shared impairments in drift rate. However, children with ASD were uniquely characterized by a wider boundary separation. Findings suggest a combination of overlapping and unique patterns of cognitive impairment for children with ASD as compared to those with ADHD, particularly when the processes underlying reaction time measures are considered separately.  相似文献

Clinical observation indicates that sexual acting out takes place during periods in which the integrity of the self is threatened by some disappointment, some frustration, or what is perceived as an unavoidable but unfair demand. Rather than confront the problem within the object relationship, the conflict is acted out. The sexual encounter reduces anxiety and facilitates the containment of depressive and aggressive feelings. Self-integration is attempted even at the risk of losing something, be it a wife, a husband, a girlfriend or the presidency. At the time it seems the only possible way to cope with painful or threatening stimuli.  相似文献

Background During recent decades, self‐regulated learning (SRL) has become a major research field. SRL successfully integrates the cognitive and motivational components of learning. Self‐regulation is usually seen as an individual process, with the social aspects of regulation conceptualized as one aspect of the context. However, recent research has begun to investigate whether self‐regulation processes are complemented by socially shared regulation processes. Aims The presented study investigated what kind of socio‐emotional challenges students experience during collaborative learning and whether the students regulate the emotions evoked during these situations. The interplay of the emotion regulation processes between the individual and the group was also studied. Sample The sample for this study was 63 teacher education students who studied in groups of three to five during three collaborative learning tasks. Method Students' interpretations of experienced social challenges and their attempts to regulate emotions evoked by these challenges were collected following each task using the Adaptive Instrument for the Regulation of Emotions. Results The results indicated that students experienced a variety of social challenges. Students also reported the use of shared regulation in addition to self‐regulation. Finally, the results suggested that intrinsic group dynamics are derived from both individual and social elements of collaborative situations. Conclusion The findings of the study support the assumption that students can regulate emotions collaboratively as well as individually. The study contributes to our understanding of the social aspects of emotional regulation in collaborative learning contexts.  相似文献

I argue that contemporary liberal theory cannot give a general justification for the institution or practice of punishment, i.e., a justification that would hold across a broad range of reasonably realistic conditions. I examine the general justifications offered by three prominent contemporary liberal theorists and show how their justifications fail in light of the possibility of an alternative to punishment. I argue that, because of their common commitments regarding the nature of justification, these theorists have decisive reasons to reject punishment in favor of a non-punitive alternative. I demonstrate the possibility of this alternative by means of a careful examination of the nature of punishment, isolating one essential characteristic—the aim to impose suffering—and showing how this characteristic need not guide enforcement. There is logical space for a forceful and coercive, yet non-punitive method of enforcement. This fact poses difficulties for many classical and contemporary justifications of punishment, but it poses particularly crippling problems for general liberal justifications.

Chronic stress effects and sex differences were examined on conditioned fear extinction. Male and female Sprague–Dawley rats were chronically stressed by restraint (6 h/d/21 d), conditioned to tone and footshock, followed by extinction after 1 h and 24 h delays. Chronic stress impaired the recall of fear extinction in males, as evidenced by high freezing to tone after the 24 h delay despite exposure to the previous 1 h delay extinction trials, and this effect was not due to ceiling effects from overtraining during conditioning. In contrast, chronic stress attenuated the recall of fear conditioning acquisition in females, regardless of exposure to the 1 h extinction exposure. Since freezing to tone was reinstated following unsignalled footshocks, the deficit in the stressed rats reflected impaired recall rather than impaired consolidation. Sex differences in fear conditioning and extinction were observed in nonstressed controls as well, with control females resisting extinction to tone. Analysis of contextual freezing showed that all groups (control, stress, male, female) increased freezing immediately after the first tone extinction trial, demonstrating contextual discrimination. These findings show that chronic stress and sex interact to influence fear conditioning, with chronic stress impairing the recall of delayed fear extinction in males to implicate the medial prefrontal cortex, disrupting the recall of the fear conditioning acquisition in females to implicate the amygdala, and nonstressed controls exhibiting sex differences in fear conditioning and extinction, which may involve the amygdala and/or corticosterone levels.  相似文献

In Skeptical idealism says that possibly nothing exists outside my own conscious mental states. Purported refutations of skeptical idealism – whether Descartes's, Locke's, Reid's, Kant's, Moore's, Putnam's, or Burge's – are philosophically scandalous: they have convinced no one. I argue (1) that what is wrong with the failed refutations is that they have attempted to prove the wrong thing – i.e., that necessarily I have veridical perceptions of distal material objects in space, and (2) that a charitable reconstruction of Kant's 'Refutation of Idealism' in fact provides a sound refutation of skeptical idealism.  相似文献

Many philosophers claim that it is always intrinsically good when people get what they deserve and that there is always at least some reason to give people what they deserve. I highlight problems with this view and defend an alternative. I have two aims. First, I want to expose a gap in certain desert‐based justifications of punishment. Second, I want to show that those of us who have intuitions at odds with these justifications have an alternative account of desert at our disposal – one that may lend our intuitions more credibility.  相似文献

A study was conducted to test experimentally whether majority members' perceptions of which acculturation strategies minority members prefer would causally impact on majority members' own acculturation preferences, especially their preference for integration. Participants (N = 113) were exposed to videos in which actors who posed as Pakistani minority members voiced different acculturation preferences (integration, assimilation, separation or control condition). Their views were presented as representative of their ethnic group. The effect of this on white British majority participants' own acculturation preferences was measured. As expected, perceived acculturation preferences significantly impacted on own acculturation preferences. In line with predictions, participants' level of prejudice significantly moderated these effects.  相似文献
