Abstract

Participants switched between two randomly ordered, two-choice reaction-time (RT) tasks, where an instructional cue preceded the target stimulus and indicated which task to execute. Task-switching cost dissipated passively while the participants waited for the instructional cue in order to know which task to execute (during the Response-Cue Interval). Switching cost was sharply reduced, but not abolished, when the participants actively prepared for the task switch in response to the instructional cue (during the Cue-Target Interval). The preparation for a task switch has shown not to be a by-product of general preparation by phasic alertness or predicting target onset. It is suggested that task-switching cost has at least three components reflecting (1) the passive dissipation of the previous task set, (2) the preparation of the new task set, and (3) a residual component.

Personality, culture, and subjective well-being: emotional and cognitive evaluations of life.

Subjective well-being (SWB), people's emotional and cognitive evaluations of their lives, includes what lay people call happiness, peace, fulfillment, and life satisfaction. Personality dispositions such as extraversion, neuroticism, and self-esteem can markedly influence levels of SWB. Although personality can explain a significant amount of the variability in SWB, life circumstances also influence long-term levels. Cultural variables explain differences in mean levels of SWB and appear to be due to objective factors such as wealth, to norms dictating appropriate feelings and how important SWB is considered to be, and to the relative approach versus avoidance tendencies of societies. Culture can also moderate which variables most influence SWB. Although it is challenging to assess SWB across societies, the measures have some degree of cross-cultural validity. Although nations can be evaluated by their levels of SWB, there are still many open questions in this area.

[Neurocognitive hypotheses of schizophrenia].

An increasingly important number of studies are reclaiming themes from the fields of the cognitive sciences and the neurosciences. It seems essential, in the face of this multiplication of the lines of research, often very different in their object and their methodology, to recall the general theoretical paradigm of the cognitive sciences, in order to shed light on the links between the different researches and this theoretical model. Moreover, the best validation of a theoretical model remaining in medicine is that of its practical application. It is today fundamental to explore the field of cognitive research for its possible impact on the domains of clinical presentation and management of patients with schizophrenia. This article proposes to address these different points.
