Effects of primary task predictability and secondary task modality on lane maintenance

The objective of this work was to investigate the effects of auditory and visuo-spatial secondary tasks on variability in lane position in predictable and unpredictable driving conditions. Sixty-six participants drove a simulated vehicle. Predictability was manipulated by adding wind gusts, and the secondary task load by either an auditory task (Experiment 1) or a visuo-spatial task (Experiment 2). Results demonstrated that in the predictable driving condition, lane position variability decreased when auditory secondary task load was given, but it was not affected by visuo-spatial secondary task load. In the unpredictable driving condition; however, while the auditory secondary task load did not affect lane position variability, visuo-spatial secondary task load increased it. The data suggests that the effects of cognitive load on lane maintenance may depend on the type of the secondary task beside predictability of primary task.     

Risk aversion in information seeking

The information gain model argues that participants select alternatives with a larger expected value of information gain. The present study investigated risk aversion in information seeking to examine whether the expected value always determines information-seeking behaviour. For this investigation, we used a scale method selection task in which participants were required to select one of two scales for weighing coins in order to find an underweight coin. Two experiments showed that participants more frequently selected the alternative that provided information gain without risk, although its expected information gain was smaller. This finding indicates the presence of risk aversion in information seeking, suggesting that information-seeking behaviour is affected by risk associated with obtaining information gain.     

Role of Secondary Stressors in the Parental Death–Child Distress Relation

This study examined the psychological consequences and secondary stressors associated with death of a parent. The sample (N = 116) consisted of 26 youths who had lost a parent to homicide, 45 youths who had lost a parent to natural death, and 45 nonbereaved youths. Youngsters completed face-to-face interviews, while their guardians completed measures assessing the children's functioning. Results based on both child and guardian reports indicated that parental death was associated with an increase in secondary stressors, regardless of the mode of death. Findings based on guardian reports also revealed that parental death was related to increased internalizing distress, and that parental death due to homicide was related to increased externalizing distress. Furthermore, secondary stressors mediated the parental death–child distress relation such that parental death led to an increase in stressors, which in turn led to increased child distress. Implications for secondary and tertiary preventive interventions are discussed.     

听力正常人与聋人短时记忆的比较研究

以视觉系列呈现,自由回忆的方法比较了听力正常人与聋人对分别被强化的厂类相似性汉语字表的短时记忆获得量。从总的平均获得量来看,两组结果没有显著差异,而从每一编码维量在短时记忆的加工过程中的作用来看,两组被试都显示出了形、义两维编码维量的作用最强,而音码的作用相对比较弱。两组被试也都显示出了明显的系列位置效应,但聋人组的次级记忆容量明显地低于听力正常组,而初级记忆容量两组没有显著差异。并对可能的机制进行了讨论。     

The potential of medicine as a resource for philosophy

In addition to the neglect of philosophy by medicine, emphasized in a recent editorial in this journal, there has been an equally important neglect of medicine by philosophy. Philosophy stands to gain from medicine in three respects: in materials, the conceptual difficulties arising in the practice of medicine being key data for philosophical enquiry; in methods, these data, through their problematic character, being ideally suited to the technique of linguistic analysis; and in results, the practical requirements of medicine placing a direct demand for progress on philosophical theory. The future of the relationship between philosophy and medicine depends on the development of a positive two-way trade between them.     

Emergent control for play responses following instructive feedback for children with autism spectrum disorder

Play provides children learning opportunities in the natural environment to acquire communication skills. While working to establish skills that may lead to additional leisure and social opportunities of children with autism spectrum disorder (ASD), procedures need to be both effective and efficient. One way to increase efficiency of teaching is through the use of instructive feedback (IF). Therefore, the purpose of the current study is to systematically replicate and extend previous research by examining if play behaviors emerge when using IF to teach conceptually related primary (i.e., tacts) and secondary targets (i.e., play skills). The results of the present study extend previous research by demonstrating the effectiveness of teaching tacts to individuals with ASD, and that using IF during tact training can help promote the acquisition of play skills.

The influence of instructive feedback presentation schedule: A replication with children with autism spectrum disorder

Instructive feedback (IF) is a modification to discrete trial instruction that may increase instructional efficiency for individuals with autism spectrum disorder. Several variations of IF have recently been evaluated in the literature; however, few studies have assessed the effectiveness and efficiency of presenting secondary targets on continuous versus intermittent presentation schedules. The current study evaluated the effectiveness and efficiency of various presentation schedules of secondary targets during discrete trial instruction. Specifically, we replicated and extended Griffen et al. (1998) by comparing a condition in which secondary targets were presented during each trial of a session, a condition in which secondary targets were presented every other trial, and a condition in which secondary targets were presented about every 4 trials. Within-subject replications were included for both participants. One of the intermittent presentation schedules was associated with the most optimal outcomes in all 4 comparisons.     

Constructive Thinking and Burnout among Secondary School Teachers

The present study investigated the relationship between Epstein’s (1998, Constructive thinking: The key to emotional intelligence. London: Praeger publisher.) components of constructive thinking and burnout as experienced by a sample of Dutch secondary school teachers. A postal questionnaire was sent to teachers from randomly selected secondary schools. The response rate was 54.1% (N=433). Four components of constructive thinking significantly contributed to the explained variance in emotional exhaustion (17%), depersonalization (21%), and personal accomplishment (20%). The results of the study suggest that secondary school teachers’ maladaptive thinking processes prevent them from rational thinking during their work, which significantly contributes to the onset of burnout. Burnout intervention programs for teachers are likely to be more effective when the participator’s maladaptive thinking system is taken into consideration. This stems from the idea that personality factors are a probably easier point of departure to tackle burnout symptoms than organizational factors.     

The ‘uncanny’, the sacred and the narcissism of culture: The development of the ego and the progress of civilization1

The report by a member of the Brazilian parliament that the rejection of physical deformity is natural and instinctive, and the Muslim reaction to the publication in the Western press of cartoons considered to be offensive to their religion, serve as an introduction to the examination of conflicts in human relations. The two episodes may be classified as representing the sense of the ‘uncanny’, attributed by Freud to the narcissism that remained from primitive cultures, in which the shadow cast by the body and the mirrored reflection of the latter probably generated the idea of soul‐which would be the narcissistic phenomenon causing the illusion of immortality. The presence of this illusion as a support for the beliefs of present‐day civilized peoples makes clear the inopportune influence of primitive mental states in areas where more developed ones should prevail. The persistence of the omnipotent thinking derived from these states provides the possibility of drawing a parallel between the development of the ego‐evolution from narcissism to object relation‐and the progress of civilization. In this context, the majority of social conflicts can be attributed to the deficient object relation resulting from the strength of primary narcissism, which generates a tendency to reject that which is different and to facilitate the emergence of destructive aggressiveness. The progress of civilization would then occur by means of a development of the ego compatible with object relations that lead to a drastic reduction in destructiveness.
