The aims of the present study are to evaluate the impact of insomnia on psychological well-being and to examine the associations of insomnia and psychological well-being with anxiety and depression. Forty-one patients attending our hospital-based Centre for sleep medicine were administered scales for the evaluation of insomnia (ISI), anxiety (STAI-Y), depression (BDI-II) and psychological well-being (PWB). The scores were compared to those of a control group of 68 subjects attending the hospital for routine examinations or as accompanying persons. Significant differences between patients and controls were detected for anxiety and depression, as well as for psychological well-being. Even if subclinical on average, anxiety and depression symptoms were significantly related to poor psychological well-being, whereas insomnia per se was not. These findings suggest that patients with insomnia report a relevant impact on their psychological well-being, and that such an impact seems to be strongly associated with concomitant subthreshold symptoms of anxiety and depression. The implications for diagnosis and treatment are discussed.  相似文献

The spatial attention mechanisms of orienting and zooming cooperate to properly select visual information from the environment and plan eye movements accordingly. Despite the fact that orienting ability has been extensively studied in infancy, the zooming mechanism – namely, the ability to distribute the attentional resources to a small or large portion of the visual field – has never been tested before. The aim of the present study was to evaluate the attentional zooming abilities of 8‐month‐old infants. An eye‐tracker device was employed to measure the saccadic latencies (SLs) at the onset of a visual target displayed at two eccentricities. The size of the more eccentric target was adjusted in order to counteract the effect of cortical magnification. Before the target display, attentional resources were automatically focused (zoom‐in) or spread out (zoom‐out) by using a small or large cue, respectively. Two different cue–target intervals were also employed to measure the time course of this attentional mechanism. The results showed that infants' SLs varied as a function of the cue size. Moreover, a clear time course emerged, demonstrating that infants can rapidly adjust the attentional focus size during a pre‐saccadic temporal window. These findings could serve as an early marker for neurodevelopmental disorders associated with attentional zooming dysfunction such as autism and dyslexia.  相似文献

In previous work we gave a new proof-theoretical method for establishing upper-bounds on the space complexity of the provability problem of modal and other propositional non-classical logics. Here we extend and refine these results to give an O(n log n)-space decision procedure for the basic positive relevance logic B+. We compute this upper-bound by first giving a sound and complete, cut-free, labelled sequent system for B+, and then establishing bounds on the application of the rules of this system.  相似文献

Neuropsychological testing aims to measure individuals' cognitive abilities (e.g. memory, attention), analysing their performance on specific behavioural tasks. Most neuropsychological tests are administered in the so-called ‘paper-and-pencil’ modality or via computerised protocols. The adequacy of these procedures has been recently questioned, with more specific concerns about their ecological validity, i.e. the relation between test scores observed in the laboratory setting and the actual everyday cognitive functioning. In developing more ecological tasks, researchers started to implement virtual reality (VR) technology as an administration technique focused on exposing individuals to simulated but realistic stimuli and environments, maintaining at the same time a controlled laboratory setting and collecting advanced measures of cognitive functioning. This systematic review aims to present how VR procedures for neuropsychological testing have been implemented in the last years. We initially explain the rationale for supporting VR as an advanced assessment tool, but we also discuss the challenges and risks that can limit the widespread implementation of this technology. Then, we systematised the large body of studies adopting VR for neuropsychological testing, describing the VR tools' distribution amongst different cognitive functions through a PRISMA-guided systematic review. The systematic review highlighted that only very few instruments are ready for clinical use, reporting psychometric proprieties (e.g. validity) and providing normative data. Most of the tools still need to be standardised on large cohorts of participants, having published only limited data on small samples up to now. Finally, we discussed the possible future directions of the VR neuropsychological test development linked to technological advances.  相似文献

Peer status – the regard other group members have of an individual – is fundamental for youth development. Different research traditions developed independent theoretical frameworks conceiving the dimensions underlying social status, and this led to identifying a variety of peer status prototypes. In this work, we explored whether a classification based on the four dimensions of popularity, aggression, dislike, and victimization could integrate the scattered peer status profiles found in the different traditions. A latent profile analysis on 16,224 European students identified the peer status prototypes of popular, bullies, disliked, victims, and average students. Both the peer- and self-reported correlates supported that the five profiles accounted for the large variety of the students' profiles in the literature. These findings suggest that the adoption of a multidimensional approach supported by advanced statistical procedures could identify students' peer status profiles more effectively, replacing classifications based on cutoffs, and leading to a unified students' classification.  相似文献

Why do poorer and less educated Asians trust their institutions of governance more than their richer and well educated counterparts, despite their disadvantaged position within society? System justification theory (SJT) assumes that this trust is driven by a system-level motivation that operates independently from social identity needs. In two nationally representative surveys spanning several years (Ntotal = 221,297), we compared SJT's explanation with a newer social identity model of system attitudes (SIMSA): that system justification amongst disadvantaged Asians is driven by a group norm for harmony, especially amongst those who are strongly invested in their national ingroup. The results supported SIMSA more than SJT. Specifically, a strong sense of national identification boosted trust in systems of governance amongst poorer and less-educated Asians, both when societal norms for harmony (Study 1), and personal endorsement of this norm (Study 2) were strong. Hence, social identity needs help to explain stronger system justification among objectively disadvantaged Asians.  相似文献
