Posttraumatic Growth in the Context of Heart Disease

The concept of positive consequences arising as a result of coping with traumatic experiences, such as life-threatening illness, represents an emerging area of empirical study in the stress and health literature. This study investigates three specific psychosocial variables (personality, social support, and coping) in relation to posttraumatic growth in a population of individuals coping with heart disease. The results indicate that Extraversion was the most significant predictor of growth, and there is evidence that Problem-Focused Coping partially mediated this relationship between Extraversion and posttraumatic growth. The role of Social Support Satisfaction in predicting growth remains unclear. Findings emphasize the importance of personal and environmental factors in psychological interventions aimed at improving the adjustment and posttraumatic growth of heart patients. Directions for future research are proposed.     

Nanoethics—A Collaboration Across Disciplines

The field of nanoscience and nanotechnology is expanding rapidly, promising great benefits for society in the form of better medicine, more efficient energy production, new types of materials, etc. Naturally, in order for the science and technology to live up to these promises, it is important to continue scientific research and development, but equally important is the ethical dimension. Giving attention to the social, ethical and legal aspects of the field, among others, will help in developing a fully responsible—and thereby capable—science and technology. Nanoethics has emerged as a field concerned with such ethical issues related to nanoscience and nanotechnology. Even though this field is relatively new, a significant amount of literature has already been published. This paper focuses on three of the major issues which are discussed in the literature of nanoethics, and also points to a certain bias in this literature. Each quite different in nature, these issues are: (1) The naming and (2) the timing of and approach to the field, as well as (3) the issue of safety. As will be seen, these issues are almost exclusively discussed by ethicists, (throughout the article, the term’ethicist’ is used in a broad definition covering philosophers, social and political scientists as well as philosophers of science) thus having no direct influence on the work being carried out by scientists. One can argue, therefore, that this bias creates a distortion of the ethical debate, making it insufficient and misleading. Ultimately, this bias is caused by the lack of communication and collaboration between ethicists on the one hand, and nanoscientists on the other. Thus, an argument is made for the different disciplines to begin collaborating, so as to more effectively and responsibly develop the field of nanoscience.     

Close encounters of the distracting kind: Identifying the cause of visual tracking errors

Why can we track only so many objects? We addressed this question by asking when and how tracking errors emerge. To test the hypothesis that many tracking errors are target/nontarget confusions emerging from close encounters, we compared standard multiple-object tracking trials with trials on which a nontarget turned a random color whenever it approached within 4° of a target. This manipulation significantly improved performance by alleviating the correspondence challenge of a close encounter. Two control experiments showed that color change benefits were not merely due to target recovery. Follow-up experiments demonstrated that color change benefits did not accrue monotonically with distance but, instead, seemed to obey a step function; and an additional experiment demonstrated that, without color changes, the frequency of close encounters predicts tracking performance. Taken together, these experiments suggest that uncertainty about target location imposes the primary constraint on tracking, at times causing errors by leading to confusions between targets and nontargets.     

An observation on the spontaneous noticing of prospective memory event-based cues

In event-based prospective memory, current theories make differing predictions as to whether intention-related material can be spontaneously noticed (i.e., noticed without relying on preparatory attentional processes). In 2 experiments, participants formed an intention that was contextually associated to the final phase of the experiment, and lures that overlapped to differing degrees with the features of the intention-related cues were embedded in the initial phase. When participants were outside of the appropriate responding context (i.e., the initial phase), they exhibited slower latencies to lures that exactly matched the features of their intention compared with other types of lures and control words. In addition, on a final remember/know recognition test, participants reported having greater subjective recollection for the occurrence of the exact-match lures. These results suggest that exact-match lures were spontaneously noticed and differentially processed in the absence of any observable preparatory attentional processes. The findings have implications for the theoretical debate over whether preparatory attention must always be relied upon to notice intention-related material.

Factor structure of overall autobiographical memory usage: the directive, self and social functions revisited

According to theory, autobiographical memory serves three broad functions of overall usage: directive, self, and social. However, there is evidence to suggest that the tripartite model may be better conceptualised in terms of a four-factor model with two social functions. In the present study we examined the two models in Danish and German samples, using the Thinking About Life Experiences Questionnaire (TALE; Bluck, Alea, Habermas, & Rubin, 2005), which measures the overall usage of the three functions generalised across concrete memories. Confirmatory factor analysis supported the four-factor model and rejected the theoretical three-factor model in both samples. The results are discussed in relation to cultural differences in overall autobiographical memory usage as well as sharing versus non-sharing aspects of social remembering.
