Age effects on different components of theory of mind

The effects of aging on the cognitive and affective dimensions of theory of mind (ToM), and on the latter’s links with other cognitive processes, such as information processing speed, executive functions and episodic memory, are still unclear. We therefore investigated these effects in young (n = 25), middle-aged (n = 20) and older adults (n = 25), using separate subjective and objective assessment tasks. Furthermore, a novel composite task probed participants’ abilities to infer both cognitive and affective mental states in an interpersonal context. Although age affected the objective ToM tests, results revealed a direct aging effect on the second-order ToM, but an indirect one on the first-order cognitive ToM, mediated mainly by age-related declines in executive functions. This study supports the notion of an age-related distinction between subjective and objective assessments of ToM, and confirms that ToM is a complex mental ability with several characteristics reliant to some extent on executive processes.     

Cognitive processes in writing during pause and execution periods

The present study investigated how writing processes are activated during pause and execution periods. In two experiments, handwriting demands were manipulated by asking participants to compose with their familiar handwriting or with a high-demanding cursive uppercase calligraphy. Experiment 1 investigated narrative writing, a task with low planning demands. Experiment 2 addressed essay writing, a task with stronger planning demands. Occurrences of processes and their cognitive effort were analysed by asking participants to respond to random auditory probes and then to report their ongoing mental activity according to learned categories referring to the planning, translating, and revising writing processes. All together, the findings indicate that demands on planning did not affect how writing processes were activated during pauses and execution periods but automaticity of handwriting did. When handwriting was effortless, translating was mostly activated in parallel with motor execution, whereas revising and planning were mainly activated during pauses. However, none of the writing processes could be characterised as being typical of pauses, since translating was activated to a similar extent as the other two processes. By contrast, when handwriting was effortful, participants shifted to a more sequential functioning and activated translating mainly during pauses.     

The Longitudinal Interplay of Adolescents' Self-Esteem and Body Image: A Conditional Autoregressive Latent Trajectory Analysis

Suppose P_I and P₂ are two competing discrimination procedures. 1Co com-, its are pare the relative discriminatory power of both procedures, test statistics are suggested for the hypothesis that P_l and P₂ performed no better than, random assignment versus the alternative that P₁ did significantly better than P_e.     

Scalar properties in human timing: conformity and violations

Data from studies of timing in human participants were reviewed with respect to their conformity to the two scalar properties of timing: mean accuracy and the scalar property of variance. Results reviewed were taken from studies of temporal generalization, temporal bisection, discrimination methods, and "classical" timing tasks such as the reproduction, production, and verbal estimation of duration. Evidence for one or both scalar properties was found in many studies, including those using children and elderly participants, but systematic violations were sometimes noted. These violations occurred (a) when very short durations (< 100 ms) were timed, (b) in situations in which timing tasks varying in difficulty were compared, (c) when classical timing tasks were employed, and (d) in situations where highly practised observers exhibited unusual patterns of variance. A later section attempted to reconcile some of these violations with an underlying scalar-consistent timing mechanism.     

Geographic region effects on adolescent physical self: An exploratory study

The objectives of this exploratory study were to examine gender differences in physical self‐concept, and the influence of geographic place of residence on both adolescents' physical self‐concept and gender differences in physical self‐concept. The Physical Self Inventory was used to measure physical self‐perceptions and global self‐esteem. Participants were 323 boys and 282 girls living in the North or South of France. First a Mann‐Whitney U test was used to assess gender differences and the influence of geographic region differences on physical self‐perceptions (physical self‐worth, physical condition, sport competence, attractive body, physical strength) and global self‐esteem. Then a Kruskal‐Wallis ANOVA for ranked data was used to assess geographic region influence on boys' and girls' physical self‐concept and global self‐esteem. The results showed that not only did boys have significantly higher physical self scores (on all scales) and global self‐esteem than girls, but also that adolescents from the North of France had higher physical self scores (on all scales) and global self‐esteem than adolescents from the South. Moreover, many differences were found between boys and girls on physical self scores (on all scales) and global self‐esteem according to their geographic place of residence. The main results showed that girls from the South had lower scores on the attractive body, physical strength, physical self‐worth, and global self‐esteem scales than all other adolescents, and that boys from the South had lower scores on the attractive body and global self‐esteem scales than did boys and girls from the North.     

Automatic knowledge learning and case adaptation with a hybrid committee approach

When Case Based Reasoning systems are applied to real-world problems, the retrieved solutions usually require adaptations in order to be used on new contexts. Therefore, case adaptation is a desirable capability. However, case adaptation is still a challenge for this research area. In general, the acquisition of knowledge for case adaptation is harder than the acquisition of cases. This paper explores the automatic learning of adaptation knowledge and explores the use of a hybrid committee approach for automatic case adaptation.

Complementary variable- and person-centred approaches to the dimensionality of work engagement: a longitudinal investigation

This study illustrates complementary variable- and person-centred approaches to the investigation of the underlying dimensionality of the work engagement construct. A sample of 730 participants completed a questionnaire twice across a four-month period. The results showed that employees’ ratings of their work engagement simultaneously reflected a global overarching work engagement construct, which co-existed with three specific dimensions (vigour, dedication, and absorption). Relying on factor scores from this initial measurement model, the present study examined latent profiles of employees defined based on their global (work engagement) and specific (vigour, dedication, and absorption) levels of work engagement. The results revealed five distinct work engagement profiles, which proved to be fully identical, and highly stable, across the two time points. These profiles characterized disengaged-vigorous, normative, totally disengaged, vigorously absorbed, and engaged yet distanced employees. These profiles were also showed to be meaningfully related to employees’ levels of stress, intentions to leave the organization, health, and job satisfaction.     

Request solicitation and semantic evocation of freedom: an evaluation in a computer-mediated communication context

The "But you are free of..." technique is a compliance procedure which solicits someone to comply with a request by simply telling him that he is free to accept or to refuse the request. This semantic evocation leads to increased compliance with the request. A new evaluation of the generality of this technique was tested in an experiment in which subjects received an anonymous electronic mail which asked them to consult the site of a humanitarian association for children. Analysis showed that, when the semantic evocation of freedom is included in the message, a higher compliance rate was observed than in a situation in which this evocation was omitted.
