The role of action in a creative theory of personality

Abstract

Psychoanalysis is a technique to let creativity develop, and thought must be a prelude to action, rather than its substitute. Megalomania, redefined according to Bion as the capacity to act responsibly, lies at the extreme positive end of the spectrum of personality.     

The human message in politics: the impact of emotional slogans on subtle conformity

The present work directly tests the persuasive potential of emotions in political slogans. Previous research that distinguished emotions on the human dimension found that individuals conform differently to the opinion of members of the in-group or the out-group when these targets expressed themselves in terms of uniquely human emotions (Vaes, Paladino, Castelli, Leyens, & Giovanazzi, 2003). In line with these findings, the present experiment tested the hypothesis that political slogans that express a uniquely human emotion and that are associated with the campaign of a political candidate who has the same political affiliation as participants (i.e., in-group) will induce more conformity reactions than a candidate of the opposing coalition (i.e., out-group) who presents similar kinds of slogans. Results confirmed this hypothesis on a subtle conformity measure and are discussed as a consequence of an infrahumanization process. Finally, possible applications of the presented findings and new avenues for future research are proposed.     

Changes in body dissatisfaction relative to gender and age: the modulating character of BMI

This study examines the level of body satisfaction in adolescents, and its association with age, sex and body mass index. A non-clinical group was made up of 935 adolescents (484 boys and 451 girls), aged between 10 and 18 years. The body image was assessed by the Body Dissatisfaction scale within the Eating Disorder Inventory (Garner, 1998, 2004) and by the indirect indicator Ideal Body Mass Index. The results showed that the Body Mass Index is an important covariable in the study of body dissatisfaction. Body dissatisfaction mean values increased in the female sample. The males' values did not change throughout adolescence.     

Psychiatric Symptoms and Quality of Life in Patients Affected by Epidermolysis Bullosa

The aim of our study was to provide a psychosocial and psychiatric evaluation of patients with epidermolysis bullosa (EB; a rare genetic disorder characterized by skin fragility), to assess psychological status, ascertain the presence of any psychiatric disorders and understand the impact of EB on quality of life. Twenty-five patients were assessed using a case record form and several standardized instruments. In 82% of patients, EB had a negative impact on quality of life and 80% of patients experienced psychiatric symptoms. Our findings revealed a high prevalence of psychosocial problems and psychiatric symptoms in patients with EB and suggested that a combined bio-psychosocial approach is the most appropriate therapeutic intervention.     

Saccades compress space, time and number

It has been suggested that space, time and number are represented on a common subjective scale. Saccadic eye movements provide a fascinating test. Saccades compress the perceived magnitude of spatial separations and temporal intervals to approximately half of their true value. The question arises as to whether saccades also compress number. They do, and compression follows a very similar time course for all three attributes: it is maximal at saccadic onset and decreases to veridicality within a window of approximately 50ms. These results reinforce the suggestion of a common perceptual metric, which is probably mediated by the intraparietal cortex; they further suggest that before each saccade the common metric for all three is reset, possibly to pave the way for a fresh analysis of the post-saccadic situation.     

Disordered eating behaviors and body image in a longitudinal pilot study of adolescent girls: What happens 2 years later?

We assessed the prospective association of risk factors for eating and body image disturbances after a 2-year follow-up in a community sample of Spanish adolescent girls. The participants included 128 Spanish girls aged 12–14, who took part in a 28-month prospective study. Aspects assessed were eating attitudes (Eating Attitudes Test), influence of the body shape model (questionnaire on influences of the aesthetic body shape model), extreme weight-control behaviors (Eating Disorder Examination-Questionnaire), body image (Body Image Questionnaire) and Body Mass Index (BMI). BMI, extreme weight-control behaviors and body image problems emerged as potential predictors of an increase in eating disturbances. An increased influence of the thinness model was significantly associated with reduced body satisfaction and body image problems. Preventive programs are needed to contribute reducing the impact of sociocultural influences with regard to thinness, the use of extreme weight-control behaviors and overweight in adolescents.     

The Role of Randomization in Bayesian and Frequentist Design of Clinical Trial

A key role in inference is played by randomization, which has been extensively used in clinical trials designs. Randomization is primarily intended to prevent the source of bias in treatment allocation by producing comparable groups. In the frequentist framework of inference, randomization allows also for the use of probability theory to express the likelihood of chance as a source for the difference of end outcome. In the Bayesian framework, its role is more nuanced. The Bayesian analysis of clinical trials can afford a valid rationale for selective controls, pointing out a more limited role for randomization than it is generally accorded. This paper is aimed to offer a view of randomization from the perspective of both frequentist and Bayesian statistics and discussing the role of randomization also in theoretical decision models.

     

Paraconsistent Informational Logic

We introduce a Paraconsistent Informational Logic that formalizes the idea of conjectures which are acceptable as to the quality and the variety of the information that they convey with respect to a given theory T, even if they are classically inconsistent with T. The work constitutes an extension of a previously developed Informational Logic for classical frameworks, where a new notion of logical entropy measure H on formulas and on proofs plays a central role.     

Influence du contexte sémantique sur la performance d'identification d'odeurs

Our olfactory knowledge is mainly implicit and the last step for cognitive processing of odors — naming — is not always performed. To facilitate naming, odor identification by forced choice between alternatives is used. However, presenting names induces semantic priming. To assess which level of spontaneous odor processing is influenced by semantic context, we compared three priming conditions. Our results indicate that the identification process is based mainly on the rejection of semantic categories that are most remote from the target, and firstly of those with a different hedonic valence. The analysis of identification errors supports the hypothesis that odor naming rests more on global semantic discriminations than on what is called lexical access in other sensory modes.     

Generating animal and tool names: an fMRI study of effective connectivity

The present fMRI study of semantic fluency for animal and tool names provides further evidence for category-specific brain activations, and reports task-related changes in effective connectivity among defined cerebral regions. Two partially segregated systems of functional integration were highlighted: the tool condition was associated with an enhancement of connectivity within left hemispheric regions, including the inferior prefrontal and premotor cortex, the inferior parietal lobule and the temporo-occipital junction; the animal condition was associated with greater coupling among left visual associative regions. These category-specific functional differences extend the evidence for anatomical specialization to lexical search tasks, and provide for the first time evidence of category-specific patterns of functional integration in word-retrieval.
