Movement sequencing and phonological fluency in (putatively) nonimpaired readers

Reading-disabled children often have accompanying deficits in motor coordination. Rather than assuming impairment of a shared neural mechanism, we conjecture that coordination difficulties that undermine normal speech would also undermine development of phonological awareness, which is necessary for reading fluency. Nonimpaired readers who vary in fluency, therefore, should also covary in coordination. Reliable interrelationships between phonological decoding skills and the speed and variability of sequentially tapping the fingers of one hand (either dominant or nondominant) were, indeed, found for college undergraduates. Reading measures that do not emphasize phonological decoding did not show the same connection. Characterizing phonological decoding as a skill and the long-term consequences of failure to master that skill suggest that it could benefit from practice even in high-literacy populations.     

The thought-action fusion scale: further evidence for its reliability and validity

Thought-action fusion (TAF) refers to a set of cognitive biases that are thought to play a role in the development of obsessional phenomena. To measure these biases, R. Shafran, D. S. Thordarson, and S. Rachman (1996; Journal of Anxiety Disorders, 10, 379-391) developed the TAF-scale. They concluded that the TAF-scale possesses adequate psychometric qualities. The current study sought to further explore the reliability and validity of the TAF-scale. Results indicate that the TAF-scale has good internal consistency. TAF-scores correlated with self-reports of obsessional problems. Furthermore, mean scores in a mixed sample of anxiety disordered patients were higher than those in a normal sample. However, temporal consistency was somewhat disappointing. Also, the question remains whether TAF is specific to obsessive-compulsive disorder or taps more pervasive biases that play a role in a variety of disorders.     

Memory for humorous cartoons

Incidental memory for three types of cartoons was compared: original cartoons, literal translations of the originals, and weird cartoons created by inserting incongruous material into the literal translations. In Experiment 1, the three types of cartoons were mixed together in lists. In Experiment 2, each list contained only two cartoon types. In both experiments, original cartoons were remembered better than the literal and the weird cartoons, whereas the literal and the weird cartoons were equally well remembered. The detection of incongruities, or attempts to resolve those incongruities, cannot adequately explain the observed humor effects. The results were also inconsistent with both rehearsal and distinctiveness interpretations. Rather, humor per se appears to support good memory performance. Perhaps participants elaborated or gave sustained attention to humorous material at the expense of less humorous material.     

Anxiety and depression as correlates of self-reported behavioural inhibition in normal adolescents

In a previous study, Muris, Merckelbach, Wessel, and Van de Ven [Psychopathological correlates of self-reported behavioural inhibition in normal children. Behav. Res. Ther. 37 (1999) 575-584] found that children who defined themselves as high on behavioural inhibition displayed elevated levels of psychopathological symptoms compared to children who defined themselves as low or middle on behavioural inhibition. The present study further examined the relationship between self-reported behavioural inhibition and anxiety disorders and depression symptoms in a large sample of adolescents aged 12-18 years (N=968). Adolescents completed a measure of behavioural inhibition and questionnaires of anxiety and depression. Results indicated that adolescents who classified themselves as high on behavioural inhibition had higher scores of anxiety and depression than adolescents who classified themselves as low or middle on behavioural inhibition. Structural equations modelling was employed to test hypothetical models on the role of behavioural inhibition in childhood anxiety and depression. It was found that a pathway in which behavioural inhibition results in anxiety, which in turn leads to depression, provided the best fit for the data.     

Anxiety sensitivity in adolescents: factor structure and relationships to trait anxiety and symptoms of anxiety disorders and depression

The current study examined the anxiety sensitivity construct in a large sample of normal Dutch adolescents aged 13-16 years (n=819). Children completed the Childhood Anxiety Sensitivity Index (CASI; Silverman, W. K., Fleisig, W., Rabian, B. & Peterson, R. A. (1991). Journal of Clinical Child Psychology, 20, 162-168) and measures of trait anxiety, anxiety disorder symptoms and depression. Results showed that (1) anxiety sensitivity as indexed by the CASI seems to be a hierarchically organized construct with one higher-order factor (i.e., anxiety sensitivity) and three or four lower-order factors, (2) anxiety sensitivity and trait anxiety were strongly correlated, (3) anxiety sensitivity was substantially connected to symptoms of anxiety disorders (in particular of panic disorder and agoraphobia) and depression, and (4) anxiety sensitivity and trait anxiety both accounted for unique proportions of the variance in anxiety disorder symptoms. Altogether these findings are in agreement with those of previous research in adult and child populations, and further support the notion that anxiety sensitivity should be viewed as an unique factor of anxiety vulnerability.     

Contextualised behavioural measurements of personality differences obtained in behavioural tests and social observations in adult capuchin monkeys (Cebus apella)

We applied a new framework for behavioural research on personality differences in 26 adult tufted capuchin monkeys. Using the Behavioural Repertoire x Environmental Situations Approach, we generated systematically 20 non-lexical emic personality constructs that have high ecological validity for this species. For construct operationalisation, we obtained 146 contextualised behavioural measures repeatedly in 15 experimental situations and 2 group situations using computerised and video-assisted methods. A complete repetition after a 2–3-week break within a 60-day period yielded significant test–retest reliability from individual-oriented and variable-oriented viewpoints at different levels of aggregation. In accordance with well-established findings on cross-situational consistency, internal consistency was only moderate. This new and important finding highlights fundamental differences between behavioural approaches and judgment-based approaches to personality differences.     

On the relations between Heinrich Scholz and Jan Łukasiewicz

The aim of the present study is (1) to show, on the basis of a number of unpublished documents, how Heinrich Scholz supported his Warsaw colleague Jan ?ukasiewicz, the Polish logician, during World War II, and (2) to discuss the efforts he made in order to enable Jan ?ukasiewicz and his wife Regina to move from Warsaw to Münster under life-threatening circumstances. In the first section, we explain how Scholz provided financial help to ?ukasiewicz, and we also adduce evidence of the risks incurred by German scholars who offered assistance to their Polish colleagues. In the second section, we discuss the dramatic circumstances surrounding the ?ukasiewiczes' move to Münster in the summer of 1944.     

Stem-Cell Spin: Covering the Hwang Affair in Science and Nature

In 2006 the South Korean cloning expert Woo Suk Hwang was found guilty of fraud and scientific misconduct. The scandal reached far beyond Hwang's own laboratory, encompassing national pride, geopolitics and global discussions of stem-cell research. But the Hwang affair was also a case of fierce competition between two of the world's leading scientific journals. Individually, Science and Nature used the Hwang affair and their unique positions to air specific and conflicting agendas resulting in completely different narratives as the scandal unfolded. In Science, where Hwang's fraudulent papers were published, the readers learned about a caring and concerned South Korean research director. Science was true to this narrative over a two-year period until finally, around Christmas 2005, there was no longer any doubt about Hwang's misbehaviour. In Nature, on the other hand, Hwang was, from the very beginning, treated with suspicion and framed as a cynical director of a cloning factory. Media studies of science and technology tend to focus almost exclusively on how this framing process works in the mass media and ignore that this process is already well under way in scientific journals that then feed into mass media news stories. Thus the news coverage of the Hwang affair in Science and Nature demonstrates that these two leading scientific journals frame their news stories in important ways that reflect (and are reproduced by) mass media reporting.     

Sex differences in theory of mind: A male advantage on Happé's “cartoon” task

It is a commonly held stereotype that women show superior performance on tests of social cognition such as face processing and theory of mind (ToM) compared to men. However, such purported differences have not been empirically tested. In this study 40 healthy men and 40 women matched for age and years of education completed a well-known experimental ToM test requiring the attribution of either physical or mental states (Happé's cartoon task). Men showed superior performance compared to women, with a medium effect size, on both the mental state and physical state cartoons. It is suggested that men may use a cognitive systemising strategy during these tasks. The results emphasise the task-specific nature of sex differences in social cognition and necessitate future work to elucidate individual differences at the interface of cognitive and affective processes.
