Factors for radical creativity, incremental creativity, and routine, noncreative performance

This study extends theory and research by differentiating between routine, noncreative performance and 2 distinct types of creativity: radical and incremental. We also use a sensemaking perspective to examine the interplay of social and personal factors that may influence a person's engagement in a certain level of creative action versus routine, noncreative work. Results demonstrate that willingness to take risks, resources for creativity, and career commitment are associated primarily with radical creativity; that the presence of creative coworkers and organizational identification are associated with incremental creativity; and that conformity and organizational identification are linked with routine performance. Theoretical and managerial implications are discussed.     

Actions taken by schools when tobacco policies are violated: associations with adolescent smoking prevalence

This study examined the association of adolescent smoking prevalence with actions taken by schools (i.e., informing parents or disciplining pupils at school) for violating the school tobacco policy. Interaction terms between actions taken by schools and role models' smoking behavior or support for adolescents were also examined. Data were collected using self-completed questionnaires from a nationally representative Norwegian sample of 15-year-olds (1,404 pupils, 51% males) and 73 staff members. Informing parents when the school tobacco policy was violated by contrast with other actions taken by schools was not associated with lower levels of adolescent smoking. Disciplining pupils was associated with lower levels of adolescent smoking but the association was no longer significant when examined together with parents' and teachers' smoking behavior or support. Exposure to parents' and teachers' smoking, and teachers' support were associated with adolescent smoking prevalence, irrespective of actions taken by schools. Identifying the mechanism under which these different home and school factors relate to adolescent smoking may be worthwhile to inform intervention initiatives.     

Complete axiomatizations for XPath fragments

We provide complete axiomatizations for several fragments of Core XPath, the navigational core of XPath 1.0 introduced by Gottlob, Koch and Pichler. A complete axiomatization for a given fragment is a set of equivalences from which every other valid equivalence is derivable; equivalences can be thought of as (undirected) rewrite rules. Specifically, we axiomatize single axis fragments of Core XPath as well as full Core XPath. Our completeness proofs use results and techniques from modal logic.     

A Stale Challenge to the Philosophy of Science

In his article “Is psychology based on a methodological error?” and based on a quite convincing empirical basis, Michael Schwarz offers a methodological critique of one of mainstream psychology’s key test theoretical axioms, i.e., that of the in principle normal distribution of personality variables. It is characteristic of this paper—and at first seems to be a strength of it—that the author positions his critique within a frame of philosophy of science, particularly positioning himself in the tradition of Karl Popper’s critical rationalism. When scrutinizing Schwarz’s arguments, however, we find Schwarz’s critique profound only as an immanent critique of test theoretical axioms. We raise doubts, however, as to Schwarz’s alleged ‘challenge’ to the philosophy of science because the author not at all seems to be in touch with the state of the art of contemporary philosophy of science. Above all, we question the universalist undercurrent that Schwarz’s ‘bio-psycho-social model’ of human judgment boils down to. In contrast to such position, we close our commentary with a plea for a context- and culture sensitive philosophy of science.     

Expressivity of Second Order Propositional Modal Logic

We consider second-order propositional modal logic (SOPML), an extension of the basic modal language with propositional quantifiers introduced by Kit Fine in 1970. We determine the precise expressive power of SOPML by giving analogues of the Van Benthem–Rosen theorem and the Goldblatt Thomason theorem. Furthermore, we show that the basic modal language is the bisimulation invariant fragment of SOPML, and we characterize the bounded fragment of first-order logic as being the intersection of first-order logic and SOPML.     

Durable and generalized effects of spatial experience on mental rotation: gender differences in growth patterns

This study addressed questions about improvement in mental rotation skills: (1) whether growth trajectories differ for men and women with higher or lower spatial experience, (2) whether videogame training has effects on performance and leads to transfer, (3) whether effects of repeated testing or training effects are durable and (4) whether transfer is durable. Undergraduates participated in repeated testing on the MRT or played the videogame Tetris. Analyses showed large improvements in mental rotation with both repeated testing and training; these gains were maintained several months later. MRT scores of men and women did not converge, but men showed faster initial growth and women showed more improvement later. Videogame training showed greater initial growth than repeated testing alone, but final performance did not differ. Effects of videogame training transferred to other spatial tasks exceeding the effects of repeated testing, and this transfer advantage was still evident after several months.

Training generalized spatial skills

Spatial transformation skills are an essential aspect of cognitive ability. These skills can be improved by practice, but such improvement has usually been specific to tasks and stimuli. The present study investigated whether intensive long-term practice leads to change that transcends stimulus and task parameters. Thirty-one participants (14 male, 17 female) were tested on three cognitive tasks: a computerized version of the Shepard-Metzler (1971) mental rotation task (MRT), a mental paper-folding task (MPFT), and a verbal analogies task (VAT). Each individual then participated in daily practice sessions with the MRT or the MPFT over 21 days. Postpractice comparisons revealed transfer of practice gains to novel stimuli for the practiced task, as well as transfer to the other, nonpracticed spatial task. Thus, practice effects were process based, not instance based. Improvement in the nonpracticed spatial task was greater than that in the VAT; thus, improvement was not merely due to greater ease with computerized testing.     

Adult age differences in attention to semantic context

In three experiments age differences in attention to semantic context were examined. The performance of younger adults (ages 18-29 years) and older adults (ages 60-79 years) on a semantic priming task indicated that both age groups could use information regarding the probability that a prime and target would be related to flexibly anticipate the target category given the prime word (Experiment 1). The timing by which target expectancies were reflected in reaction time performance was delayed for older adults as compared to younger adults, but only when the target was expected to be semantically unrelated to the prime word (Experiment 2). When the target and prime were expected to be semantically related, the time course of priming effects was similar for younger and older adults (Experiment 3). Together the findings indicate that older adults are able to use semantic context and the probability of stimulus relatedness to anticipate target information. Although aging may be associated with a delay in the timing by which controlled expectancies are expressed, these findings argue against an age-related decline in the ability to represent contextual information.

Psychological Reactance and Adolescents' Attitudes Toward Tobacco-Control Measures

The theory of psychological reactance predicts that, to the extent that smoking-control measures are perceived as threatening the individual's freedom to choose among behavioral alternatives, they may be met with resistance. Data were collected from a national representative sample of 2,400 young people (ages 16–20) by telephone interviews. Dispositional reactance was shown to be associated with smoking. Principal components analyses revealed that a distinction should be made between attitudes toward weak and attitudes toward strong smoking-control measures. Attitudes toward strong measures were particularly negative among regular smokers. Among regular smokers, dispositional reactance was found to be significantly associated with attitudes toward strong tobacco-control measures. Processes of psychological reactance deserve attention when designing smoking control programs.
