The death of handwriting: secondary effects of frequent computer use on basic motor skills

The benefits of modern technologies such as personal computers, in-vehicle navigation systems, and electronic organizers are evident in everyday life. However, only recently has it been proposed that the increasing use of personal computers in producing written texts may significantly contribute to the loss of handwriting skills. Such a fundamental change of human habits is likely to have generalized consequences for other basic fine motor skills as well. In this article, the authors provide evidence that the skill to produce precisely controlled arm-hand movements is related to the usage of computer keyboards in producing written text in everyday life. This result supports the notion that specific cultural skills such as handwriting and typing shape more general perceptual and motor skills. More generally, changing technologies are associated with generalized changes of the profile of basic human skills.     

Structural correspondence between theories and convergence to truth

While “scientism” is typically regarded as a position about the exclusive epistemic authority of science held by a certain class of “cultured despisers” of “religion”, we show that only on the assumption of this sort of view do purportedly “scientific” claims made by proponents of “intelligent design” appear to lend epistemic or apologetic support to claims affirmed about God and God’s action in “creation” by Christians in confessing their “faith”. On the other hand, the hermeneutical strategy that better describes the practice and method of Christian theologians, from the inception of theological reflection in the Christian tradition, acknowledges the epistemic authority of the best available tests for truth in areas of human inquiry such as science and history. But this strategy does not assume that such tests, whose authority must be regarded as provisional, provides authority for the warrant of affirming claims constituting the confessed “faith”. By attributing theological import to claims advanced by appeal to the best available tests for truth in the practice of science, supporters of ID not only confuse the epistemic authority of these tests with the normative authority of a faith community’s confessional identity, but impute to scientific tests for truth a sort of authority that even goes beyond the “methodological naturalism” against which they counterpose their claims.     

Status der psychosomatischen Forschung im deutschsprachigen Bereich

Psychosomatic medicine aims at exploring the relationships between biological, psychological and social factors in onset, maintenance and treatment of psychosomatic disorders. The present article describes current topics and methodological approaches in the field of psychosomatic research. A bibliometric analysis of two German journals in 2009 and 2010 was conducted, yielding 43 articles dealing with different aspects of psychosomatic medicine: chronic illness, somatoform disorders and pain, trauma-related disorders, borderline personality disorder and attention deficit hyperactivity disorder. The results show that psychosomatic research covers a variety of topics with different research designs. However, there is still a paucity of controlled studies in the field.     

Cost-effectiveness of Internet-based cognitive behavior therapy vs. cognitive behavioral group therapy for social anxiety disorder: results from a randomized controlled trial

Social anxiety disorder (SAD) is highly prevalent and associated with a substantial societal economic burden, primarily due to high costs of productivity loss. Cognitive behavior group therapy (CBGT) is an effective treatment for SAD and the most established in clinical practice. Internet-based cognitive behavior therapy (ICBT) has demonstrated efficacy in several trials in recent years. No study has however investigated the cost-effectiveness of ICBT compared to CBGT from a societal perspective, i.e. an analysis where both direct and indirect costs are included. The aim of the present study was to investigate the cost-effectiveness of ICBT compared to CBGT from a societal perspective using a prospective design. We conducted a randomized controlled trial where participants with SAD were randomized to ICBT (n = 64) or CBGT (n = 62). Economic data were assessed at pre-treatment, immediately following treatment and six months after treatment. Results showed that the gross total costs were significantly reduced at six-month follow-up, compared to pre-treatment in both treatment conditions. As both treatments were equivalent in reducing social anxiety and gross total costs, ICBT was more cost-effective due to lower intervention costs. We conclude that ICBT can be more cost-effective than CBGT in the treatment of SAD and that both treatments reduce societal costs for SAD.

Religious versus Conventional Internet-based Cognitive Behavioral Therapy for Depression

The accessibility and efficacy of two Internet-supported interventions for depression: conventional cognitive behavioral therapy (C-CBT) and religious CBT (R-CBT) were investigated. Depressed participants (N = 79) were randomly assigned to either active treatment or wait-listed control group. Self-report measures of depression, anxiety, and life quality were collected before, immediately after, and 6 months after the intervention. Significant differences among the three conditions emerged at post-intervention with medium to large effect sizes (Cohen’s d between 0.45 and 1.89), but no differences between the R-CBT and C-CBT were found. However, the addition of religious components to CBT contributed to the initial treatment appeal for religious participants, thus increasing the treatment accessibility.     

Personality traits,learning stratigies,and performance

The objective of this research is to analyse the relationships between personality traits, learning strategies, and performance. Two multivariate studies (N=139 and N=92) were conducted. In both studies factor analyses of the learning strategies yielded two factors. One factor, labelled, ‘learning discipline’, correlated highly with the Conscientiousness scale and the other factor, labelled, ‘elaboration’, correlated with the Openness of Experience scale. In Study 1, about 17 per cent of the variance in college grades was accounted for by personality scales and learning strategies. In Study 2, learning strategies accounted for about 31 per cent of the variance in college grades. Path analyses showed that the relations between basic personality traits and grades were mediated by the learning strategies.     

Learning to learn during visual discrimination in group housed dwarf goats (Capra hircus)

Using an automated learning device, we investigated "learning to learn" by dwarf goats (Capra hircus) in what was for them a familiar environment and normal social settings. Nine problems, each consisting of four discriminable black symbols, each with one S-super+ and three different S-super(-), were presented on a computer screen. Mean daily learning success improved over the course of the first four problems, and the improvement was maintained throughout the remaining five problems. The number of trials to reach the learning criterion decreased significantly beginning with problem four. Such results may be interpreted as evidence that the goats were developing a learning set. In the present case, the learning set appeared to have two components. One involved gaining familiarity and apparent understanding of the learning device and the basic requirements of the discrimination task. The second component involved learning potential error factors to be ignored, as well as learning commonalities that carried over from one problem to the next. Among the error factors, evidence of apparent preferences for specific symbols was seen, which had a predictable effect on performances.
