The function debate: between “cheap tricks” and evolutionary neutrality

We examine the use of the notion of natural selection in the philosophical debate on functions in biology. This debate has been largely shaped by the way in which different accounts assess various selective pressures in justifying claims about biological functions. Cummins (Functions: new essays in the philosophy of psychology and biology. Oxford University Press, Oxford, pp 157–172, 2002), one of the main proponents of the causal role account of biological functions, argues that a correctly understood neo-Darwinian notion of natural selection has nothing to do with functional talk in biology. In this paper, we counter Cummins’ account by showing that progress in the molecular approaches to evolutionary biology—specifically scientific data available in neo-functionalization research—offers valuable support to the etiological selectionist approach to functions in biological and biologically-related sciences. Finally, we use the presented data to build our own account of biological functions, which tries to avoid the wrong turns taken by both major strands in the biological function debate, namely causal role and etiological accounts. According to our account, the function of a certain gene or a protein in the biological system that contains it is a particular causal activity, or a group of causal activities whose manifestation is in a specific way determined by corresponding mechanisms of genetic expression. Also, we argue that in many important cases this particular expression of genetic activity was positively selected at a certain point in evolutionary history. Since we take selection as an important but not the only factor that grounds biological functions, we are committed to a weak etiological account.     

Epistemic justification in the context of pursuit: a coherentist approach

The aim of this paper is to offer an account of epistemic justification suitable for the context of theory pursuit, that is, for the context in which new scientific ideas, possibly incompatible with the already established theories, emerge and are pursued by scientists. We will frame our account paradigmatically on the basis of one of the influential systems of epistemic justification: Laurence Bonjour’s coherence theory of justification. The idea underlying our approach is to develop a set of criteria which indicate that the pursued system is promising of contributing to the epistemic goal of robustness of scientific knowledge and of developing into a candidate for acceptance. In order to realize this we will (a) adjust the scope of Bonjour’s standards—consistency, inferential density, and explanatory power, and (b) complement them by the requirement of a programmatic character. In this way we allow for the evaluation of the “potential coherence” of the given epistemic system.     

Spatial navigation deficits in amnestic mild cognitive impairment with neuropsychiatric comorbidity

Aims: To find out whether neuropsychiatric comorbidity (comMCI) influences spatial navigation performance in amnestic mild cognitive impairment (aMCI).

Methods: We recruited aMCI patients with (n = 21) and without (n = 21) neuropsychiatric comorbidity or alcohol abuse, matched for global cognitive impairment and cognitively healthy elderly participants (HE, n = 22). They completed the Mini-Mental State Examination and a virtual Hidden Goal Task in egocentric, allocentric, and delayed recall subtests.

Results: In allocentric navigation, aMCI and comMCI performed significantly worse than HE and similarly to each other. Although aMCI performed significantly worse at egocentric navigation than HE, they performed significantly better than patients with comMCI.

Conclusions: Despite the growing burden of dementia and the prevalence of neuropsychiatric symptoms in the elderly population, comMCI remains under-studied. Since trials often assess “pure” aMCI, we may underestimate patients’ navigation and other deficits. This finding emphasizes the importance of taking account of the cognitive effects of psychiatric disorders in aMCI.     

Professionals’ Reflections About the Impact of Digital Technologies on Eating Disorders

The aim of this study was to explore how professionals working with clients who suffer from eating disorders reflect the impact of digital technologies on their clients. Interviews with 30 professionals were conducted. A qualitative analysis revealed the following areas: (a) the attributes of technologies that influence people with eating disorders, (b) the characteristics of people with eating disorders that influence their interaction with digital technologies, (c) the risks of technology usage, and (d) the benefits of technology usage. The results are discussed with respect to the Rodgers’s theoretical model explaining technology–eating disorder relations and the implications for practice.     

Apathy or alienation? Political passivity among youths across eight European Union countries

Abstract

Political participation is one of the most studied aspects of the contemporary development of western democracies. A recent trend focuses the lack of political participation among younger generations. At the same time, the last decades have also witnessed a growth in the share of young European Union (EU) citizens who express alienation, and distrust toward social and political institutions at the national as well as the European level. By studying young people across different countries of the EU, the current study aims to examine if youths’ political passivity is better explained by political apathy or alienation. Our analyses are based on a comparative survey data collected by the Catch-EyoU project comprising approximately 4 454 late adolescents assembled from eight member countries of the EU. Results from logistic regressions predicting non-voting from apathy and alienation support the idea that political passivity is best understood as the result of political apathy. Moreover, it seems that the underlying separator of apathetic and alienated youths is cognitive awareness of political life. These results are discussed in relation to potentially built-in paradoxes of apathy present in efficient and well-functional welfare-state democracies.     

Dissecting the expanded cognitive reflection test: an item response theory analysis

This study presents a psychometric evaluation of the Expanded Cognitive Reflection Test (CRT7) based on item response theory. The participants (N?=?1204) completed the CRT7 and provided self-reported information about their cognitive styles through the Preference for Intuition and Deliberation Scale (PID). A two-parameter logistic model was fitted to the data to obtain the item difficulty and discrimination parameters of the CRT7. The results showed that the items had good discriminatory power (αs?=?.80 ? 2.92), but the range of difficulty was restricted (βs ranged from ?.60 to .32). Moreover, the CRT7 showed a pattern of correlations with the PID which was similar to that of the original CRT. When taken together, these results are evidence of the adequacy of the CRT7 as an expanded tool for measuring cognitive reflection; however, one of the newer items (the pig item) was consistently problematic across analyses, and so it is recommended that in future studies it should be removed from the CRT7.

Discovering New Ways of Moving: Observational Analysis of Motor Creativity While Dancing Contact Improvisation and the Influence of the Partner

Contact improvisation (CI) is a form of dance based on motor creativity, improvisation and the physical contact between different improvisers dancing together. This will generate different ways of moving and a varied use of motor creativity depending on the dancers involved. This study aims to observe the differences in movement generation depending on the partner by using OSMOS (Observational System of Motor Skills; Castañer & Camerino 2006; Castañer et al., 2009). Four contact improvisers were video‐recorded while dancing in duets. Data were analysed by three observers using Theme Coder software (Magnusson, 1996) for the detection of T‐patterns and the production of event frequency charts. The results show that (1) the motor skills that appear most frequently are the conduction of partners, elevations, spatial level changes and turns; (2) motor creativity is affected by the partner, as there is a reciprocal influence in the dance; and (3) motor creativity is enhanced by interaction with a partner.     

Tolerance more than equality? Two facets of tolerance towards immigrants among Czech adolescents

ABSTRACT

This study focused on facets of tolerance towards immigrants among Czech adolescents, drawing on data from 9^th and 10^th graders (n = 2003). The aim of this study was to examine the relationship between tolerance towards immigrants and support for democracy, repression potential, right-wing authoritarianism, and out-group trust. Results showed that tolerance towards immigrants should be treated as a two-dimensional concept: support for equal rights, focused on equality in labour market, housing or access to education, and support for cultural rights, encompassing acceptance of immigrants’ rights to practice their culture and religion. We found that Czech adolescents were generally more supportive of equal rights than of cultural rights, and that out-group trust explained most of the variance for both dimensions of tolerance towards immigrants. The study also indicated ambiguous effects in the relationship between right-wing authoritarianism, repression potential and support for equal/cultural rights of immigrants with out-group trust used as moderating variable.
