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.

An analog-to-digital converter for on-line use in response dynamics research

A general-purpose translator was designed for an analysis of the dynamic properties of the intracranially reinforced (ICR) barpressing response. It is used principally as an animal training device.
