The cognitive and neural basis of option generation and subsequent choice

Decision-making research has thoroughly investigated how people choose from a set of externally provided options. However, in ill-structured real-world environments, possible options for action are not defined by the situation but have to be generated by the agent. Here, we apply behavioral analysis (Study 1) and functional magnetic resonance imaging (Study 2) to investigate option generation and subsequent choice. For this purpose, we employ a new experimental task that requires participants to generate options for simple real-world scenarios and to subsequently decide among the generated options. Correlational analysis with a cognitive test battery suggests that retrieval of options from long-term memory is a relevant process during option generation. The results of the fMRI study demonstrate that option generation in simple real-world scenarios recruits the anterior prefrontal cortex. Furthermore, we show that choice behavior and its neural correlates differ between self-generated and externally provided options. Specifically, choice between self-generated options is associated with stronger recruitment of the dorsal anterior cingulate cortex. This impact of option generation on subsequent choice underlines the need for an expanded model of decision making to accommodate choice between self-generated options.     

An Accumulation of Negative Life Events and the Construction of Alexithymia: A Longitudinal and Clinical Approach

We began the study with a theoretical comparison of the concepts of alexithymia and operative thought in terms of etiology as well as with a specific approach to comparing the concepts using the Rorschach Inkblot Method (Rorschach, 1921 Rorschach, H. 1921. Psychodiagnostic, Paris, , France: Presses Universitaires de France.  [Google Scholar]) with both Exner's (1986) Comprehensive System and the Parisian School (Chabert, 1983 Chabert, C. 1983. Le Rorschach en clinique adulte: Interprétation psychanalytique [The Rorschach in adult clinical settings: Psychoanalytic interpretation], Paris, , France: Dunod.  [Google Scholar], 1987 Chabert, C. 1987. La Psychopathologie à travers le Rorschach [Psychopathology throughout the Rorschach], Paris, , France: Dunod.  [Google Scholar]; Rausch de Traubenburg, 2000) methods of coding and interpretation. We then present a longitudinal clinical study of a woman suffering perinatal depression starting at 8 months gestation until 34 months postpartum. The case shows how an accumulation of stressful and traumatic life events in the early perinatal period generates a reactive, structured alexithymia. This psychic process transforms an initial acceptance of therapy into a refusal to engage in a therapeutic alliance along with persistent depressive symptoms, impaired quality of life, and maladaptive coping strategies.     

Death, Cadavers and Post-mortem Biomedical Research: A Point of View from a Christian Community

Facing modern developments of medicine and biomedical researches, religious communities are a strong source of ethics principles and orientations. Human dignity does not disappear after life, in a context of biomedical research on cadavers. Moral, political, social and scientific aspects of research on human cadavers (mainly autopsies) have been widely discussed in biomedical publications, whereas the religious ones (which could be predominant for some) have rarely been analyzed and presented. This article will present the results of a survey carried out a French Benedictine Abbey (relative to death, cadaver’s status and biomedical research) and subsequent Christian background according to canonic texts and practical cases from anthropological, historical, archeological and biomedical origin.     

Attachment and spiritual coping in patients with chronic schizophrenia

Many studies on spirituality in psychosis have shown that, compared to a nonclinical population, patients make more use of spiritual beliefs/religious practices to deal with their problems. Our research question was to test whether attachment to spiritual figures could be a good explanation for religious coping strategies in patients with psychosis. First, adult attachment was investigated in 28 patients with chronic psychosis and 18 controls, using the Adult Attachment Interview. Diagnostic evaluations were performed with the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (4th edition, Text Revision) Axis I disorders and symptomatic evaluation with the Brief Psychiatric Rating Scale. Results also show a high prevalence of insecure avoidant attachment in patients, and suggest that a significant part of religious coping might be explained by the theory of attachment (64% of the patients, 78% of controls). The implications of these results are interpreted in light of correspondence and compensation hypotheses.     

Verbal Learning Changes in Older Adults Across 18 Months

ABSTRACT

The major aim of this study was to investigate individual changes in verbal learning across a period of 18 months. Individual differences in verbal learning have largely been neglected in the last years and, even more so, individual differences in change in verbal learning. The sample for this study comes from the Zurich Longitudinal Study on Cognitive Aging (ZULU; Zimprich et al., 2008a Zimprich, D., Martin, M., Kliegel, M., Dellenbach, M., Rast, P. and Zeintl, M. 2008a. Cognitive ability structure in old age: First results from the Zurich Longitudinal Study on Cognitive Aging. Swiss Journal of Psychology, 67: 177–195. [Crossref], [Web of Science ®] , [Google Scholar]) and comprised 336 older adults in the age range of 65–80 years at first measurement occasion. In order to address change in verbal learning we used a latent change model of structured latent growth curves to account for the non-linearity of the verbal learning data. The individual learning trajectories were captured by a hyperbolic function which yielded three psychologically distinct parameters: initial performance, learning rate, and asymptotic performance. We found that average performance increased with respect to initial performance, but not in learning rate or in asymptotic performance. Further, variances and covariances remained stable across both measurement occasions, indicating that the amount of individual differences in the three parameters remained stable, as did the relationships among them. Moreover, older adults differed reliably in their amount of change in initial performance and asymptotic performance. Eventually, changes in asymptotic performance and learning rate were strongly negatively correlated. It thus appears as if change in verbal learning in old age is a constrained process: an increase in total learning capacity implies that it takes longer to learn. Together, these results point to the significance of individual differences in change of verbal learning in the elderly.     

A Longitudinal Study of Perceived Conflict and Instrumental Relationships Between Life Contexts Among Adolescents: The Role of Self-Determined Motivation

This study is a 3-year follow-up of 746 adolescents on the evolution of perceived conflicting or instrumental relationships between sport, education, and friendship. School-to-sport conflict increases with age, in particular among boys, and is maximal among adolescents self-determined toward sport but not toward school. Sport-to-school instrumentality increases among boys, decreases among girls, and is positively linked to contextual self-determined motivation. Friendship-to-sport conflict is more prevalent at the beginning and the end of adolescence, among girls, and is negatively linked to friendship self-determined motivation. Sport-to-friendship instrumentality decreases during adolescence, in particular for females, and is positively associated with contextual self-determined motivation.     

The relation between risk perceptions and physical activity among older adults: A prospective study

Past studies have found that risk perceptions of suffering from diseases play an important role in the development of intentions to perform physical activity (PA). According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent methodological developments on the importance of study design and risk perception assessment, the purpose of the present study was to examine the risk-perceptions–PA relationship among older adults. Participants (N?=?143) aged from 61 to 70 years initially underwent measurement of risk perceptions, baseline PA, socio-demographic and health factors. Six months later, they were asked about their PA participation. Multiple regression analyses revealed that perceived risk of suffering from diseases and conditions without regular PA participation was an independent positive predictor of later PA, over and beyond baseline behaviour, socio-demographic and health variables. This study fills a gap in the existing literature on the PAs of older adults and reveals that risk perceptions are directly linked to their participation. In addition, it extends existing knowledge in health psychology on the behaviour motivation hypothesis, and emphasises the necessity of methodological adjustments when assessing the risk-perception–behaviour relationship.     

Mirror Neuron System and Mentalizing System connect during online social interaction

Two sets of brain areas are repeatedly reported in neuroimaging studies on social cognition: the Mirror Neuron System and the Mentalizing System. The Mirror System is involved in goal understanding and has been associated with several emotional and cognitive functions central to social interaction, ranging from empathy to gestural communication and imitation. The Mentalizing System is recruited in tasks requiring cognitive processes such as self-reference and understanding of other’s intentions. Although theoretical accounts for an interaction between the two systems have been proposed, little is known about their synergy during social exchanges. In order to explore this question, we have recorded brain activity by means of functional MRI during live social exchanges based on reciprocal imitation of hand gestures. Here, we investigate, using the method of psychophysiological interaction, the changes in functional connectivity of the Mirror System due to the conditions of interest (being imitated, imitating) compared with passive observation of hand gestures. We report a strong coupling between the Mirror System and the Mentalizing System during the imitative exchanges. Our findings suggest a complementary role of the two networks during social encounters. The Mirror System would engage in the preparation of own actions and the simulation of other’s actions, while the Mentalizing System would engage in the anticipation of the other’s intention and thus would participate to the co-regulation of reciprocal actions. Beyond a specific effect of imitation, the design used offers the opportunity to tackle the role of role-switching in an interpersonal account of social cognition.     

From the Analysis of Verbal Data to the Analysis of Organizations: Organizing as a Dialogical Process

The analysis of conversational turn-taking and its implications on time (the speaker cannot completely anticipate the future effects of her/his speech) and sociality (the speech is co-produced by the various speakers rather than by the speaking individual) can provide a useful basis to analyze complex organizing processes and collective action: the actor cannot completely anticipate the future effects of her/his acts and the act is co-produced by multiple actors. This translation from verbal to broader classes of interaction stresses the performativity of speeches, the importance of the situation, the role of semiotic mediations to make temporally and spatially distant “ghosts” present in the dialog, and the dissymmetrical relationship between successive conversational turns, due to temporal irreversibility.
