Powered by Imagination: Nanobots at the Science Photo Library

Nanobots have been a key image deployed in nanoscience and nanofiction. At present nanobots are still largely ‘imaginary’. But what do ‘imaginary’ nanobots look like, how are they visually and imaginatively constructed and what functions are they envisioned to have? And what can such images tell us about the aesthetic and cultural conventions and metaphors that are employed, and expectations and visions created or engineered, in the process of ‘visualizing’ nanoscience and nanotechnology for science and society? To answer these questions images of nanobots available at the Science Photo Library were studied. Nanobots were envisioned as ‘working’ mostly in futuristic domains of health and medicine. Most nanobots were artistically rendered as familiar objects or animals, as fulfilling useful functions in healthcare, rather than as running wild and causing harm. Such images were displayed mostly to engage lay publics with biotechnology and nanotechnology. By selectively using metaphors, images of nanobots tended to assimilate the unknown into the known and the unfamiliar into the familiar. This assimilation invites viewers to react to these images as if nanobots already existed and as if they were normal. Thus the images open up a space for ‘normalizing’ this new, rather speculative technology; it is framed in such a way as to invite public acceptance and even excitement.     

Social Support,Coping Strategies and Psychological Well-being among Young People Awaiting Employment

Abstract

It is usually thought that unemployed people who experience high levels of social support show greater psychological well-being than those who experience less social support. This relationship is moderated by factors like the coping strategies used to face the disturbance. This article describes a study carried out on a population of young French people awaiting employment following a training course. The results show that the effects of social support on psychological well-being are modulated by the way individuals manage the relationships between the different domains of their life (family, professional, personal, and social).     

Mass Media as Alcohol Educator for Everyone? Effects of Portrayed Alcohol Consequences and the Influence of Viewers’ Characteristics

ABSTRACT

Many correlative and experimental studies indicate that the portrayal of alcohol in the mass media impacts viewers’ alcohol expectancies, attitudes, and behaviors. Based on social cognitive theory, the portrayed consequences and the valence of the character experiencing these consequences are important to consider when investigating the portrayal of alcohol in the mass media. However, experimental studies manipulating character valence and consequences are scarce. This study presents an experimental examination of an adult sample, manipulating the occurrence of consequences (no consequences, positive consequences, and negative consequences), as well as character valence (a positive or negative character). We investigated the effects of media portrayals on positive and negative alcohol expectancies, as well as on attitudes toward alcohol. Furthermore, the moderating role of participants’ level of alcohol consumption was considered. We found main effects only on the negative alcohol expectancies, supporting the differentiation of alcohol expectancies and attitudes. However, the valence of the depicted character did not moderate the impact of the portrayed consequences. Interaction effects of participants’ individual levels of alcohol consumption and portrayals of consequences of alcohol consumption in the mass media were uncovered. This finding has important implications for further research and prevention efforts directed at risk groups.     

Die DPG-Praxis-Studie

All psychotherapeutic methods must be scientifically evaluated. Empirical evaluation of evidence is a prerequisite for acceptance as scientific psychotherapy as well as for payment by health insurance. Currently the psychotherapy methods accepted within the German health system (behavioural therapy, psychodynamic psychotherapy, and analytic psychotherapy) are reviewed by a governmental evaluation committee concerning evidence, necessity and cost-effectiveness. The DPG practice study has basically two aims: 1) to conduct a large naturalistic study to investigate effectiveness, sustainability and economic aspects of psychodynamic and analytic psychotherapy and 2) to offer a framework for psychoanalytic institutes, members, candidates or groups to realize own research ideas by collecting additional data within the study. The present article describes the background, main research questions, structure and design of the DPG practice study with regard to the evaluation questions.     

Cross-modal training induces changes in spatial representations early in the auditory processing pathway

In the ventriloquism aftereffect, brief exposure to a consistent spatial disparity between auditory and visual stimuli leads to a subsequent shift in subjective sound localization toward the positions of the visual stimuli. Such rapid adaptive changes probably play an important role in maintaining the coherence of spatial representations across the various sensory systems. In the research reported here, we used event-related potentials (ERPs) to identify the stage in the auditory processing stream that is modulated by audiovisual discrepancy training. Both before and after exposure to synchronous audiovisual stimuli that had a constant spatial disparity of 15°, participants reported the perceived location of brief auditory stimuli that were presented from central and lateral locations. In conjunction with a sound localization shift in the direction of the visual stimuli (the behavioral ventriloquism aftereffect), auditory ERPs as early as 100 ms poststimulus (N100) were systematically modulated by the disparity training. These results suggest that cross-modal learning was mediated by a relatively early stage in the auditory cortical processing stream.     

What matters in implicit task sequence learning: perceptual stimulus features, task sets, or correlated streams of information?

Implicit task sequence learning may be attributed to learning the order of perceptual stimulus features associated with the task sequence, learning a series of automatic task set activations, or learning an integrated sequence that derives from 2 correlated streams of information. In the present study, our purpose was to distinguish among these 3 possibilities. In 4 separate experiments, we replicated and extended a previous study by Heuer, Schmidtke, and Kleinsorge (2001). The presence or absence of a sequence of tasks, as well as that of a sequence of different task-to-response mappings, was manipulated independently within experiments. Evidence of implicit sequence learning was found only when correlated sequences of tasks and mappings were present. No sequence learning effects were found when only a single task sequence or a single mapping sequence was present, even when the structure of the single sequence was identical to the structure of the integrated sequence of task-mapping combinations. These results suggest that implicit task sequence learning is not dependent on either perceptual learning of stimulus features or automatic task-set activation per se. Rather, it appears to be driven by correlated streams of information.     

„Insightfulness Assessment“

In this article a new method of Oppenheim and Koren-Karie (2002) is presented for the assessment of the insightfulness of parents regarding their children’s inner world. Parental insightfulness involves the capacity to see things from the child’s point of view, and is based on a) insight into the child’s motives, b) a complex view of the child and c) openness to new information about the child. Insightfulness is seen as the capacity underlying sensitive and positive parenting and providing the context for secure child-parent attachment. In the assessment of insightfulness parents view video segments of their interactions with their children and are subsequently interviewed regarding their children’s and their own thoughts and feelings during the segments. Interviews are transcribed, rated in 10 scales and subsequently classified into 1 of 4 groups. The first of the four groups indicates insightfulness while the remaining three indicate a lack of insightfulness.
