Attention during visual secondary tasks in driving: Adaptation to the demands of the driving task

Visual attention in driving with visual secondary task is compared for two visual secondary tasks. N = 40 subjects completed a 1 h test drive in a motion-base driving simulator. During the drive, participants either solved an externally paced, highly demanding visual task or a self paced menu system task. The secondary tasks were offered in defined critical and non-critical driving situations. Eye movement behavior was analyzed and compared for both tasks. Before starting the secondary tasks, eye movement behavior shows a smaller standard deviation of gaze as well as longer fixation durations for both tasks. The comparison between the two tasks indicates that drivers use the possibilities the self paced task offers: during the secondary task, they monitor the driving scene with longer fixations and show a greater standard deviation of gaze position. Furthermore, independently of the type of secondary task, drivers adapt their eye movement behavior to the demands of the situation. In critical driving situations they direct a larger proportion of glance time to the driving task. Last, the relation between glance behavior and collisions is analyzed. Results indicate that collisions go together with an inadequate distribution of attention during distraction. The results are interpreted regarding the attentional processes involved in driving with visual secondary tasks. Based on the similarities and differences between the two secondary tasks, a cognitive approach is developed which assumes that the control of attention during distraction is based on a mental situational model of the driving situation.     

A preliminary examination of the effect of massage on state body image

Evidence suggests positive effects of massage on psychological health; however, little is known about the effects of massage on body image. This research examined the effect of massage on state body image as well as relations between trait body image and attitudes toward massage. Forty-nine female university students were randomly assigned to either a massage condition or a control condition. It was hypothesized that participants in the massage condition would report improved state body image following the intervention when compared to participants in the control condition. As predicted, participants in the massage condition reported a more favorable state body image than participants in the control condition post-manipulation. Certain body image evaluations were moderately associated with views that massage is pleasurable, with the link between Body Areas Satisfaction and viewing massage as pleasurable reaching significance. Research is needed to determine the mechanism/s through which massage improves body image.     

Accounting for fluctuations in body dissatisfaction

The present study evaluated whether the strength of relationship between contextual cues (presence of company and mood) and state body dissatisfaction varied as a function of individual differences in key trait measures (body shame, body surveillance tendencies, internalization of appearance standards, and trait affect) which have been linked to trait body dissatisfaction. Fifty-five undergraduate women completed a questionnaire containing the trait-based measures and then carried a Personal Digital Assistant (PDA) for a 7-day period. The PDA prompted participants six times daily to self-report their current mood and state body dissatisfaction. Multi-level modeling revealed that individual differences in body shame predicted inter-individual variability in the strength of the relationships between presence of company and state body dissatisfaction, and positive mood and state body dissatisfaction. Trait positive affect also explained variance in the positive mood state-body dissatisfaction relationship. The implications of the findings for prevention of body image disturbances are discussed.     

Bodily movement – The fundamental dimensions

Bodily movement has become an interesting topic in recent philosophy, both in analytic and phenomenological versions. Philosophy from Descartes to Kant defined the human being as a mental subject in a material body. This mechanistic attitude toward the body still lingers on in many studies of motor learning and control. The article shows how alternative philosophical views can give a better understanding of bodily movement. The article starts with Heidegger's contribution to overcoming the subject-object dichotomy and his new understanding of the primacy of the practical involvement with the surrounding world. Heidegger, however, in many ways neglected the role of the human body. Merleau-Ponty took a huge step forward when he focused on the bodily intentionality of our interaction with the world. The next step was taken by Samuel Todes who presented a better understanding of how we are bodily oriented in space. After having seen how the body is oriented outward towards the environment it is proper that the final part of this article goes inward toward the role of bodily awareness and the role of proprioception in human movement. The goal of the presentation is to contribute to a better understanding of what goes on in sport. The article therefore uses examples from sport, especially football, to show the relevance of the new insights for sport studies.     

类比推理的眼动研究:揭示个体类比推理策略发展的有效手段

近年来,研究者利用眼动技术具有高时间精度的优势,探明不同年龄群体完成类比推理过程的眼动模式特点并得出其在进行类比推理时所使用的策略。基于类比推理的眼动研究发现了三种典型的类比推理策略——项目优先策略、结构匹配策略和语义限制策略。成人更多表现为项目优先策略,儿童更多表现为语义限制策略。未来研究可以优化类比推理眼动指标,尤其是全局扫视路径的计算方法,并重点关注特殊群体的类比推理眼动模式以及关注类比推理策略与其他认知能力的交互作用。

Further developments of the concept of fantasy

After the Isaacs' seminal work on the nature and function of unconscious phantasy (1948), several authors (mostly in the British Society) have reflected on the topic and tried to extend the concept of fantasy. In this paper I shall examine the contributions of Winnicott, Gaddini, Joseph and Anne Marie Sandler that aim at broadening this psychoanalytic concept. The authors that I have considered share a focus mostly on the early stages of child development. Both Winnicott and Gaddini belong to a line of thinking that explores the vicissitudes of the primary emotional development of the infantile self (in the mother‐infant relationship) involving the earliest processes of holding and bodily and kinaesthetic fantasy that form the bodily integrity of the person. The Sandlers focused mostly on the concept of the past unconscious understood as a place of primitive vicissitudes with a deficit in figuration where the process of repression is missing. The present unconscious phantasy (that is located in the here and now) has the function of rendering the past unconscious phantasy partly accessible; otherwise it would remain unknowable.     

Interoceptive Abnormalities and Suicidality: A Systematic Review

Dysfunction of interoception (i.e., difficulties sensing the physiological state of one's own body) is increasingly linked to different mental health disorders and suicidal outcomes. The aim of this study was to systematically review the literature on the association between suicidality and interoception, as well as identify potential confounders and mediators of the relationship. We conducted a systematic review of four databases, allowing for critical examination of the role of different measures of interoception (accuracy, sensibility, awareness, cognitive/emotional evaluation) across the suicide continuum (ideation, plans, attempts, deaths). The search strategy identified 22 studies (14,988 participants). Preliminary but limited evidence was found for impaired interoceptive accuracy among those reporting suicide attempt histories. We found evidence of interoceptive sensibility disturbances across the suicide continuum, including experiences of not trusting one’s own body sensations and impaired abilities to sustain and control attention to such sensations. Consistent evidence was also reported for disturbances related to cognitive and emotional evaluations of interoceptive sensations. The latter was particularly pronounced for those reporting suicide attempts, relative to those reporting suicidal thinking or planning alone. Overall, this review’s results suggest that interoceptive abnormalities are potentially important indicators of risk for suicidal thinking, intentions, and behaviors. However, due to the inconsistent adjustment for variables of interest, and cross-sectional designs, it is unclear whether interoceptive changes and disturbances have a direct role, or whether the association is explained and mediated by key third variables (e.g. depression, disordered eating, emotional dysregulation). We discuss the implications with respect to suicidal risk and therapeutic interventions.
