The functional characteristics of visuo-spatial serial memory and its sensitivity to irrelevant visual information are examined in the present study, through the investigation of the sandwich effect (e.g., Hitch, 1975). The memory task was one of serial recall for the position of a sequence of seven spatially and temporally separated dots. The presence of irrelevant dots interpolated with to-be-remembered dots affected performance over most serial positions (Experiment 1) but that effect was significantly reduced when the interpolated dots were distinct from the to-be-remembered dots by colour and shape (Experiment 2). Parallels are made between verbal and spatial serial memory, and the reduction of the sandwich effect is discussed in terms of the contribution of perceptual organisation and attentional factors in short-term memory. 相似文献

This paper describes a simple and efficient method to increase the D/A output resolution of an 8-bit microcomputer, as exemplified on the Apple II. The “distributive method” can increase the final output resolution up to 32K with two 8-bit analogic channels. A simple interface based on balanced sets of resistors and driver software are described. Some applications are also reported. 相似文献

The reliability, discriminant validity, and construct validity of the Personality Assessment Inventory (PAI) — a multidimensional self-report measure of abnormal personality traits — were examined within the Australian context. Subjects included 151 normals, 30 alcoholics, and 30 schizophrenic patients. A subsample of 70 nonpsychiatric adults responded to the PAI items twice over a test-retest interval of 28 days. The resulting median retest coefficient was 0.7, indicating less than optimal stability. The median alpha (KR21) coefficient was 0.8, suggesting somewhat narrow measurement scales. A significant multivariate main effect was obtained across groups after the effects of age and gender were removed. Multiple comparisons for each of the PAI scales revealed significant differences between the respective groups, as discussed. A higher-order scale factoring did not strongly support the purported PAI structure. In reanalyses of the correlation matrices included in the Professional Manual, the purported PAI factor structure was unable to be replicated for the standardization clinical sample (N=1246), and a confirmatory factor analysis using the normative (validation) correlational data (N=1000) revealed poor fit indices, raising further concerns about construct validity. 相似文献

Alexithymia refers to a specific disturbance in emotional processing that is manifested through difficulties in identifying and verbalizing feelings, and a tendency to focus and amplify the somatic sensations accompanying emotional arousal. The main purpose of the present study was to investigate the stability levels of alexithymia related to changes in emotional distress levels caused by university exams at two different times: after and during the exams. We carried out a 17-week follow-up on 36 university students, alexithymic features and self-reported emotional distress (anxiety, depression and somatic illness) were measured. Whereas emotional distress measures changed significantly during the follow-up period, the degree of alexithymia remained unchanged. We conclude therefore that alexithymia presents a constant trait in non-clinical samples, in contrast to anxiety and depression, which are state phenomena, influenced by stress levels. 相似文献

In the present research the authors examined the time course of binocular integration in goal-directed aiming and grasping. With liquid-crystal goggles, the authors manipulated vision independently to the right and left eyes of 10 students during movement preparation and movement execution. Contrary to earlier findings reported in catching experiments (I. Olivier, D. J. Weeks, K. L. Ricker, J. Lyons, & D. Elliott, 1998), neither a temporal nor a spatial binocular advantage was obtained in 1 grasping and 2 aiming studies. That result suggests that, at least in some circumstances, monocular vision is sufficient for the precise control of limb movements. In a final aiming experiment involving 3-dimensional spatial variability and no trial-to-trial visual feedback about performance, binocular vision was associated with greater spatial accuracy. Binocular superiority appeared to be most pronounced when participants were unable to adjust their limb control strategy or procedure on the basis of terminal feedback about performance. 相似文献

This research examined the simultaneous influences of emotional intelligence, adjustment to university, authoritative versus other parenting style, and high school average on first year university students’ grade point average (GPA) via structural equation modeling. The participants were 299 first year students from the social science faculty at Laurentian University, Canada. The sample was comprised of 86 males (28.7 %) and 213 females (71 %); most students (96.7 %) were between the ages of 17 and 23. The results showed that high school average had a direct influence on first year university GPA. Emotional Intelligence was not directly associated with first year university GPA, but it was significantly associated with adjustment to university which in turn was significantly associated with the first year GPA. This tends to suggest that the influence of emotional intelligence on academic achievement may be mediated by adjustment to university. Furthermore, parenting style (authoritative versus other) had a significant influence on adjustment to university but not on emotional intelligence and university GPA. Students who came from families with authoritative parenting styles tended to be better adjusted than students who came from families with other parenting styles (authoritarian and permissive). Problem behaviors such as alcohol use, academic dishonesty and academic procrastination were found to have a negative influence on university GPA and adjustment to university. In conclusion, emotional intelligence and an authoritative parenting style are influential in enhancing adjustment to university which in turns affects academic achievement in university. 相似文献

Over the past decade there has been a growing number of studies examining the prayer content of people’s personal prayers left in intercessory church-related contexts. Since 2012, these studies have extended to include the cathedral intercessory prayer board and the online intercessory prayer site. Both ‘the cathedral’ and ‘the online site’ are distinctive contexts for intercessory prayer in terms of their openness and accessibility for a broad range of people, who are allowed to enter and use these prayer facilities. What is not known, however, is whether the cathedral prayer board and the online site are functioning in similar ways. This study presents an analysis of 500 prayers posted on the Church of England’s ‘Pray One for Me’ (POFM) website over a period of six months in 2012. The analysis employs the ap Siôn Analytic Framework for Intercessory Prayer (apSAFIP), which distinguishes among prayer intention, prayer reference, and prayer objective. The results of the analysis are compared with the results from recent cathedral studies employing the same analytic tool, and it is concluded that these two prayer contexts are functioning differently. 相似文献
