Predictive Pointing Movements and Saccades Toward a Moving Target

The authors investigated whether and, if so, how velocity information is used to control predictive manual pointing movements and saccades. Participants (N = 6) intercepted an occluded moving target as if it were still visible. They kept their eyes fixated while the target moved. The target traveled over a fixed distance and changed its velocity on the way. The presentation time of the final velocity was varied. Both the eye and the hand overshot the slow target and undershot the fast target, particularly when the duration of the final velocity was short. Thus, responses were biased in the direction of the target's initial velocity. The error seemed to arise because participants did not take their latency into account when aiming at the target. Instead, they strategically aimed farther ahead when the target was fast. Amplitude was also more related to the position of velocity change than to final velocity duration. Both findings suggest that target velocity is not extrapolated but that individuals add an increment to the position of velocity change.     

The Efficacy of Systemic Therapy for Childhood and Adolescent Externalizing Disorders: A Systematic Review of 47 RCT

Systemic (family) therapy is a widely used psychotherapy approach. However, most systematic efficacy reviews have focused solely on “family‐based treatment” rather than on the theoretic orientation “systemic therapy.” We systematically review trials on the efficacy of systemic therapy for the treatment of childhood and adolescent externalizing disorders. All randomized (or matched) controlled trials (RCT) evaluating systemic/systems‐oriented therapy in various forms (family, individual, group, multi‐family group therapy) with child or adolescent index patients (0–17 years) suffering from mental disorders were identified by data base searches and cross‐references. Inclusion criteria were as follows: index patient diagnosed with a DSM‐ or ICD‐listed mental disorder, and trial published in any language up to the end of 2011. The RCTs were analyzed for their research methodology, interventions applied, and results (postintervention; follow‐up). A total of 47 trials from the United States, Europe, and China, published in English, German, and Mandarin, were identified. A total of 42 of them showed systemic therapy to be efficacious for the treatment of attention deficit hyperactivity disorders, conduct disorders, and substance use disorders. Results were stable across follow‐up periods of up to 14 years. There is a sound evidence base for the efficacy of systemic therapy for children and adolescents (and their families) diagnosed with externalizing disorders.     

A Note on the Hierarchical Model for Responses and Response Times in Tests of van der Linden (2007)

Findings suggest that in psychological tests not only the responses but also the times needed to give the responses are related to characteristics of the test taker. This observation has stimulated the development of latent trait models for the joint distribution of the responses and the response times. Such models are motivated by the hope to improve the estimation of the latent traits by additionally considering response time. In this article, the potential relevance of the response times for psychological assessment is explored for the model of van der Linden (Psychometrika 72:287–308, 2007) that seems to have become the standard approach to response time modeling in educational testing. It can be shown that the consideration of response times increases the information of the test. However, one also can prove that the contribution of the response times to the test information is bounded and has a simple limit.     

Reliabilism, bootstrapping, and epistemic circularity

Pretheoretically we hold that we cannot gain justification or knowledge through an epistemically circular reasoning process. Epistemically circular reasoning occurs when a subject forms the belief that p on the basis of an argument A, where at least one of the premises of A already presupposes the truth of p. It has often been argued that process reliabilism does not rule out that this kind of reasoning leads to justification or knowledge (cf. the so-called bootstrapping-problem or the easy-knowledge-problem). For some philosophers, this is a reason to reject reliabilism. Those who try to defend reliabilism have two basic options: (I) accept that reliabilism does not rule out circular reasoning (or bootstrapping), but argue that this kind of reasoning is not as epistemically “bad” as it seems, or (II) hold on to the view that circular reasoning (or bootstrapping) is epistemically “bad”, but deny that reliabilism really allows this kind of reasoning. Option (I) has been spelled out in several ways, all of which have found to be problematic. Option (II) has not been discussed very widely. Vogel (J Philos 97:602–623, 2000) considers and quickly dismisses it on the basis of three reasons. Weisberg (Philos Phenomenol Res 81:525–548, 2010) has shown in detail that one of these reasons is unconvincing. In this paper I argue that the other two reasons are unconvincing as well and that therefore option (II) might in fact be a more promising starting point to defend reliabilism than option (I).     

“Secularization of Consciousness” or Alternative Opportunities? The Impact of Economic Growth on Religious Belief and Practice in 13 European Countries

This research note contributes to an evaluation of the validity of secularization theory by studying the relationship between economic modernization and patterns of religious change. Both the disenchantment narrative of Berger and Weber and the existential security perspective of Inglehart hypothesize that economic development should be accompanied by a weakening of religious values. Using macro‐level panel regressions, my analysis reveals that while economic growth is directly associated with diminishing church attendance rates, it is not directly associated with a decline in belief. The relation between economic growth and religious decline is therefore not primarily mediated by a “secularization of consciousness.” Findings instead indicate that economic prosperity leads to a change in consumption patterns on the part of individuals due to increased income and availability of alternative, secular opportunities to meet needs previously fulfilled by traditional religion. A decline in religious belief may occur as a secondary consequence of this behavioral change, since diminishing worship attendance rates reduce the influence of religion on value socialization.     

Internet Communication and Its Relation to Well-Being: Identifying Some Underlying Mechanisms

Abstract

The aim of this study was to improve our insight into the relation between Internet communication and well-being. Drawing on a survey of 816 adolescents, we initially found that Internet communication was negatively related to well-being. However, when adolescents’ (a) closeness to friends and (b) tendency to talk with strangers online were included in our structural equation model, an opposite pattern of results emerged. First, the direct negative relation between Internet communication and well-being disappeared. Second, via the mediator closeness to friends, Internet communication showed a positive influence on well-being. Third, not Internet communication per se, but Internet communication with strangers accounted for a negative effect on well-being. Fourth, the effects of both Internet communication and Internet communication with strangers on well-being were most adverse for lonely adolescents.     

Adolescents' Exposure to Sexually Explicit Internet Material and Sexual Preoccupancy: A Three-Wave Panel Study

The main aim of this study was to investigate whether adolescents' use of sexually explicit Internet material (SEIM) increased their sexual preoccupancy (i.e., a strong cognitive engagement in sexual issues). Further, we wanted to know (a) whether subjective sexual arousal mediated a potential influence of exposure to SEIM on sexual preoccupancy and (b) whether this process differed between male and female adolescents. Over the course of one year, we surveyed 962 Dutch adolescents aged 13–20 years three times. Structural equation modeling showed that exposure to SEIM stimulated sexual preoccupancy. This influence was fully mediated by subjective sexual arousal from SEIM. The effect of exposure to SEIM on subjective sexual arousal did not differ between male and female adolescents. The findings suggest that a sexualized media environment may affect adolescents' sexual development beyond traditionally studied variables, such as sexual attitudes and sexual behavior.     

How planning facilitates behaviour change: Additive and interactive effects of a randomized controlled trial

Planning interventions have proven effective to change behaviour. However, less is known about their underlying mechanisms. To better understand the processes by which planning interventions unfold their effects, a combined action planning and coping planning intervention was tested in a field setting, with the focus on mediating and moderating effects of theory‐derived social‐cognitive variables. In a randomized controlled trial, 374 employees of a logistics company were asked to participate in either a combined action planning and coping planning intervention or an active control group. Four weeks later, self‐reported changes in fruit and vegetable intake, action planning, coping planning, intentions and self‐efficacy were measured. Single and simultaneous mediating effects on behaviour were tested with intention‐to‐treat analyses, along with interaction effects between planning processes. Action planning and coping planning mediated intervention effects on fruit and vegetable intake not only separately, but also simultaneously (multiple mediation). Action planning and coping planning had main and interactive effects on behaviour change (moderation). Action planning and coping planning may exert both additive and synergistic effects on health behaviour change. Volitional interventions should include both action planning and coping planning components and stimulate the use of planning in everyday life. Copyright © 2009 John Wiley & Sons, Ltd.
