Inferentialism,degrees of commitment,and ampliative reasoning

Our purpose in this paper is to contribute to a practice-based characterization of scientific inference. We want to explore whether Brandom’s pragmatist–inferentialist framework can suitably accommodate several types of ampliative inference common in scientific reasoning and explanation (probabilistic reasoning, abduction and idealisation). First, we argue that Brandom’s view of induction in terms of merely permissive inferences is inadequate; in order to overcome the shortcoming of Brandom’s proposal, we put forward an alternative conception of inductive, probabilistic reasoning by appeal to the notion of degrees of commitment. Moreover, we examine the sorts of inferential commitments operative in other types of ampliative inferences, such as abduction or reasoning involving idealizations and assumptions. We suggest that agents engaging in these forms of reasoning often undertake restricted inferential commitments, whose scope and reach are more limited that in the case of the commitments associated with full beliefs.

     

Sexual Attitudes and Double Standards: A Literature Review Focusing on Participant Gender and Ethnic Background

We conducted a review of literature regarding sexual attitudes and double standards, focusing on participant gender and ethnic background. We found that men had more permissive sexual attitudes than women, and that African Americans had the most permissive sexual attitudes, followed by White Americans, then by Hispanic Americans and Asian Americans. The literature regarding sexual double standards was mixed; some studies showed evidence of continued sexual double standards and some studies showed the absence of sexual double standards. In some studies, men were more likely to endorse the sexual double standard than women. We found only one article addressing sexual double standards using ethnic background as a quasi-independent variable; this research revealed that non-North American (Russian and Japanese) samples were more likely to endorse the traditional double standard, that sex is more acceptable for men than for women.

Comparative analysis of the perception of school violence in teachers, pupils, and families

The main aim of the present study is to analyze the opinion of pupils, families and teachers in four European countries (Spain, Hungary, Austria and the Czech Republic) on the prevalence of violent behavior and other problematic aspects related to coexistence in schools, and on the way in which individuals are personally affected by them. For this purpose, a single instrument was used. From the results obtained it emerges, first of all, that there are significant differences depending on who is analyzing the school problems. Generally, families perceive the problems analyzed as less common and feel less affected by them personally. Hungary was considered to be the country with the lowest levels of school violence. Pupils indicate their concern about the high levels of lack of motivation or boredom, whilst teachers are more preoccupied about the serious problems of coexistence, due in particular to the presence or use of weapons and drugs and to intercultural conflicts.     

Needs and Cognition/Behavior Patterns at Work and the Big Five: An assessment of the Personality and Preference Inventory‐Normative (PAPI‐N) from the perspective of the five‐factor model

This study examined the relationship between psychological needs and cognition/behavior patterns at work as measured by the Personality and Preference Inventory – Normative (PAPI‐N) and the five‐factor model of personality as measured by the NEO Five Factor Inventory (NEO‐FFI) in a sample of 91 working adults and 71 psychology undergraduates who worked or had some work experience. Our results showed significant and theoretically congruent correlations between the PAPI‐N scales and the measures of the five‐factor model. These correlations were similar to those found using alternative instruments to measure Murray's needs. Despite the differences in the conceptual origins of the PAPI‐N and the NEO‐FFI and divergences in the aspects of personality measured by the two inventories, joint and interbattery factor analyses showed that most of the needs and cognition/behavior patterns measured by the PAPI‐N can be meaningfully organized within the framework of the five‐factor model. These results provide further empirical evidence for the validity of the five‐factor model and the PAPI‐N, although they also point out personality aspects that are not encompassed by the five‐factor model.     

Distinct ways of timing movements in bimanual coordination tasks: contribution of serial correlation analysis and implications for modeling

Bimanual coordination dynamics have been conceived as the outcome of a global coordinative system, and coordination stability properties and theories of underlying processes have often been generalized over various bimanual tasks. In unimanual timing tasks it has been shown that different timing processes are involved according to tasks, yielding distinctive correlation properties in the within-hand temporal patterns. In this study we compare unimanual with bimanual, tapping with oscillation, and self-paced with externally paced tasks, and we analyze the correlation properties of temporal patterns at both the component level and the coordinative level. Results show that the distinctive signatures of event-based versus emergent, and self-paced versus synchronization timing control known from unimanual tasks persist in the corresponding bimanual coordination tasks. Accordingly, we argue that these different timing processes, and related temporal patterns at the component level, constitute a task-dependent background on which coordination builds. One direct implication of these results is that the bimanual coordination paradigm should be considered multifaceted and not governed by some unitary generic principle. We discuss the need to assess the relationship between temporal patterns at the component level and the collective level, and to integrate serial (long-range) correlation properties into bimanual coordination models. Finally, we test whether the architectures of current bimanual coordination models can account for the experimentally observed serial correlations.     

Relative Deprivation and Social Identity in Times of Dramatic Social Change: The Case of Nurses1

In the present study, an integration of relative deprivation theory and social identity theory is proposed to account for people's reactions to dramatic changes affecting their daily lives. Data collected among nurses (n = 108) indicate that feelings of relative deprivation are influenced by different perceptions of organizational change. Path analysis shows that feelings of social relative deprivation derive from negative changes that are numerous, and that temporal relative deprivation is experienced as a result of negative changes that are rapid. In terms of the link between social identity and relative deprivation, 2 contrasting approaches were tested. Analyses support the view that in‐group identification acts as a precursor, rather than as a consequence, of relative deprivation.     

Grammatical category-specific deficits in bilingual aphasia

We report the naming performance of an early and highly proficient Spanish-Catalan bilingual (JPG) suffering from Primary Progressive Aphasia (PPA). JPG's performance revealed a grammatical category-specific deficit, with worse performance in naming verbs than nouns. This dissociation was present in oral and written naming and in his two languages, and it seems to stem from damage to, at least, the lexical level. Despite the fact that JPG's performance was qualitatively very similar across languages, his second language seemed to be more affected than his first language. These results indicate that the cortical organization of the two languages of highly proficient bilinguals follow similar organizational principles, one of this principles being grammatical class.
