Philosophia - In this article, I aim at showing how powers may ground different types of probability in the universe. In Section 1 I single out several dimensions along which the probability of...     

Das Leibgedächtnis. Ein Beitrag aus der Phänomenologie Husserls

Die Unterscheidung von verschiedenen Ged?chtnisformen und -systemen sowie die Beziehung zwischen Ged?chtnis und Leiblichkeit stehen sowohl im Fokus der kognitionswissenschaftlichen, als auch der ph?nomenologischen Debatte. In diesem Artikel wird versucht, beide Ans?tze zum Thema in einen Dialog zu bringen. Das Leibged?chtnis wird hier zun?chst ph?nomenologisch als der konkreteste Ausdruck des impliziten Ged?chtnisses bestimmt. Basierend auf Edmund Husserls Analysen zum Zeitbewusstsein und zur leiblichen Erfahrung werden folglich die Strukturen und die Dynamik des Leibged?chtnisses hervorgehoben. Dabei wird gezeigt, dass das Leibged?chtnis sowohl in den Wahrnehmungsprozessen als auch in der Gestaltung des pr?reflektiven leiblichen Selbstbewusstseins eine unentbehrliche Rolle spielt. Schlie?lich wird die Relevanz der durchgeführten ph?nomenologischen Analysen im Rahmen der aktuellen Debatte über Ged?chtnissysteme in den Kognitionswissenschaften diskutiert.     

Overcoming negative reactions of nonbeneficiaries to employment equity: the effect of participation in policy formulation

In 2 experimental studies, we examined a way to overcome nonbeneficiaries' resistance to employment equity (EE) policies-participation in formulating the policy. We operationalized participation in terms of instrumental versus noninstrumental voice and proposed that nonbeneficiaries would be more likely to support an EE policy when allowed instrumental participation in the policy's development. Further, we proposed psychological ownership as the mediating mechanism underlying the effects of instrumental participation. Study 1 examined participation effects for a gender-based EE policy and Study 2 for a race-based EE policy. As predicted, we found that nonbeneficiaries (men in Study 1; Whites in Study 2) in the instrumental participation condition expressed greater behavioral intentions to promote the policy (Studies 1 and 2) and were more likely to engage in a behavior promoting the policy (Study 2). We also found support for psychological ownership as the underlying mediating mechanism in both studies. Contributions to theory and practice are discussed.     

The relationship between multisensory integration and IQ in children

It is well accepted that multisensory integration has a facilitative effect on perceptual and motor processes, evolutionarily enhancing the chance of survival of many species, including humans. Yet, there is limited understanding of the relationship between multisensory processes, environmental noise, and children's cognitive abilities. Thus, this study investigated the relationship between multisensory integration, auditory background noise, and the general intellectual abilities of school-age children (N = 88, mean age = 9 years, 7 months) using a simple audiovisual detection paradigm. We provide evidence that children with enhanced multisensory integration in quiet and noisy conditions are likely to score above average on the Full-Scale IQ of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). Conversely, approximately 45% of tested children, with relatively low verbal and nonverbal intellectual abilities, showed reduced multisensory integration in either quiet or noise. Interestingly, approximately 20% of children showed improved multisensory integration abilities in the presence of auditory background noise. The findings of the present study suggest that stable and consistent multisensory integration in quiet and noisy environments is associated with the development of optimal general intellectual abilities. Further theoretical implications are discussed.     

Eye movements and bisection behavior in spatial neglect syndrome: representational biases induced by the segment length and spatial dislocation of the stimulus

The present study explored behavioral and eye-movement measures in unilateral neglect patients in response to online bisection task (unfilled gap line). Two different tasks supported the bisection performance, a pointing and a grasping strategy. It was explored whether these different strategies may influence subjects' behavioral and eye-movement measures in response to different segment features: segment length (from shorter to longer) and segment spatial dislocation (from right to left spatial location). Consistent spatial biases were found for both bisection responses, fixation count, and duration, as well as for the first fixation count in case of pointing task. An "extreme-left" gradient effect was suggested and discussed, with patients' behavioral and eye measures more impaired. On the contrary, the patients' performance overlaps with the controls' one in case a grasping task. The direct link of visual pointing and grasping strategy, respectively, with the two cortical ventral and dorsal pathways was adduced to explain our results.

Effectiveness of parent counselling in eating disorders

ABSTRACT

Eating Disorders (ED) are often severe illnesses entailing a heavy burden for families. Family therapy is recommended for young patients, but only a few studies have investigated therapeutic interventions with families tailored also to adult and longstanding patients. We recruited 87 families with daughters affected by an ED, aiming to assess the effectiveness of eight sessions of parent counselling. The primary outcome was the improvement of parents' coping abilities to achieve more effective support skills. Before treatment, 54% of parents showed poor coping resources whereas 43.7% of the sample improved after parent counselling. Parents with good coping resources responded significantly better to this treatment. Although future research is warranted, these preliminary findings support the effectiveness of parent counselling in ED.     

The strategic role of language abstraction in achieving symbolic and practical goals

This article addresses the role of linguistic abstraction in the achievement of symbolic and practical goals. Reviewing evidence from laboratory studies, we first elaborate on the power of language as a means of ingroup enhancement or outgroup derogation under different intergroup conditions. We then report several experimental and archival studies that showed how language serves the achievement of different practical goals such as initiating, maintaining, and ending romantic relations, accounting for individual and group decisions, maintaining or obtaining political and gender power, and persuading others. The analysis of open-ended language measures—which represents a methodological thread of the reviewed studies—shows how language is strategically moulded according to individual and group goals in laboratory as well as in real-life contexts. The implications of the interplay among language, cognition, and action are addressed.     

Urban Conflicts and Immigrants’ Engagement. A Comparative Pragmatic Analysis of Two Northern Italian Cities

At the beginning of the 1990s, urban safety entered political and media debates in Italy. Since then, an anti-social behaviour discourse has diverted attention towards newcomers who have repeatedly appeared as the main cause of urban safety conflicts. Italian scholars have often described these actors as the passive target of safety policies. The main aim of this paper is to demonstrate that in fact some residents of immigrant origins have engaged in the game of urban conflicts. A comparative analysis will be carried out to discuss contentious dynamics in two Italian cities, by building on ethnographical data collected between 2009 and 2010. The two cities which are the object of the analysis are Verona and Modena. They are situated in the so-called Third Italy, in the north of the country, and are characterised by diverging political subcultures. A consistent part of studies on immigrants’ collective action has drawn from the structural perspective and has insisted on political opportunities as a crucial explanatory variable. This contribution will show the added value of complementing this interpretation with a pragmatic sensitive one. Residents of immigrant origins will be observed while undertaking their thorny path of engagement characterised by the capacity to adapt, construct more or less lasting agreements with institutional and non-institutional actors and propose alternative solutions to influence a given context. Ultimately, this will also provide an example of how a pragmatic sensitive stance can help study politics in a continuum with policies, a preoccupation which lies at the core of urban theory.     

IRT Test Equating in Complex Linkage Plans

Linkage plans can be rather complex, including many forms, several links, and the connection of forms through different paths. This article studies item response theory equating methods for complex linkage plans when the common-item nonequivalent group design is used. An efficient way to average equating coefficients that link the same two forms through different paths will be presented and the asymptotic standard errors of indirect and average equating coefficients are derived. The methodology is illustrated using simulations studies and a real data example.
