We are made,not born: Empiricism is existentially useful

The perennial “nativist-empiricist” debate in developmental science has far-reaching relevance in our existence. Two studies conducted under the terror management framework tested whether the empiricist developmental conception serves distal defensive purposes. Experiment 1 highlights the palliative existential effect of the empiricist conception since participants who read an empiricist essay exhibited less death thoughts than participants who read a nativist essay or a control essay. Experiment 2 gives support to the distal defensive function of the empiricist conception by showing that, unlike with the nativist or the control essay, people under mortality salience exhibited a higher need to rely on empiricism than participants in the control pain condition. The existential advantage of empiricism is explained by the fact that human development is shaped by a meaningful cultural blueprint. Our results are discussed in terms of the ontological and existential benefits of contemplating human intrinsic identity, ranging from its biology to its social behaviors as primarily influenced by the cultural environment.     

Influence of emotional valence and arousal on the spread of activation in memory

Controversy still persists on whether emotional valence and arousal influence cognitive activities. Our study sought to compare how these two factors foster the spread of activation within the semantic network. In a lexical decision task, prime words were varied depending on the valence (pleasant or unpleasant) or on the level of emotional arousal (high or low). Target words were carefully selected to avoid semantic priming effects, as well as to avoid arousing specific emotions (neutral). Three SOA durations (220, 420 and 720 ms) were applied across three independent groups. Results indicate that at 220 ms, the effect of arousal is significantly higher than the effect of valence in facilitating spreading activation while at 420 ms, the effect of valence is significantly higher than the effect of arousal in facilitating spreading activation. These findings suggest that affect is a sequential process involving the successive intervention of arousal and valence.     

Motor imagery in spinal cord injury patients: Moving makes the difference

Both real action control and execution and motor imagery abilities require knowledge of the spatial location of body parts, in other words efference copy information and feedbacks from the sensory system (Frith et al., 2000, Philos. Trans. R. Soc. Lond. B. Biol. Sci., 355, 1771). Spinal cord injuries induce severe motor disability, due to a damage of the descending motor pathways (Cramer et al., 2007, Exp. Brain. Res., 177, 233). Patients' motor imagery competences are variably reported as either normal or defective (Decety & Boisson, 1990, Eur. Arch. Psychiatry Clin. Neurosci., 240, 39; Lacourse et al., 1999, Behav. Brain Sci., 104, 73). We explored biomechanical constraint effects in Spinal Cord Injury (SCI) patients, as they are considered the most reliable indexes of motor imagery abilities (Parsons, 1987b, Cogn. Psychol., 19, 178). Sixteen spinal cord injuries patients and 16 neurologically unimpaired subjects have been administered with (1) the Hand Laterality Task (HLT), in which subjects were asked to judge the laterality of a rotated hand; and (2) the Mirror Letter Discrimination Task (MLD), in which subjects were asked to judge if a rotated character was in its correct upright position or mirror‐reversed form. Our patients did not present the effect of stimulus orientation, neither did they show any effect related to biomechanical constraints. Based on these data, the hypothesis is that SCI patients' performance may be ascribed to the use of a different strategy to solve the tasks, based on memory rather than on mental rotation.     

Medical Trainees’ Readiness for the Promotion of Sexual Health in Tunisia: A Cross Sectional Study

In the Arab and Muslim countries, there are several taboos of sexuality. To overcome the latter, and to distinguish between cultural and scientific data, sexual education is a key measure, especially during medical studies. The purpose of this study was to assess the knowledge of the Tunisian medical trainees and to identify their sources of information concerning sexuality. We conducted a survey among medical trainees of the faculty of medicine of Sfax, in Tunisia. An anonymous questionnaire was distributed to 171 and completed by 157 trainees (91.8%). The sources of knowledge about sexuality were: friends (81.5%; N = 128), internet (77.1%; N = 121), television and movies (68.2%; N = 107), courses at the faculty (40.1%; N = 63) and parents (22.9%; N = 36). The score of correct answers was higher than or equal to 75% for 28 trainees (17.8%). It was on average 63.3%. It was correlated with male gender (p = 0.006), being a second-year trainee (p = 0.017) and television and movies as a source of knowledge about sexuality (p = 0.008). Masturbation was considered pathological by 17.2% of participants (N = 27). A 5-min period of intercourse was deemed sufficient to have a female orgasm by 44 trainees (28%). Andropause and menopause are inconsistent with a satisfying sexuality according to 44.6% (N = 70) and 56.1% (N = 88) of the participants respectively.     

Can spatialisation be extended to episodic memory and open sets?

The SPoARC effect (Spatial Positional Associated Response Codes) has only been observed in working memory (WM) using closed sets. It is interpreted as showing that individuals spatialise to-be-remembered items in a left-to-right fashion, using spatialisation as context. Given that context is crucial for episodic memory (EM), we tested if this effect could be observed in EM by using 15-word lists taken from an open set. After each list, 30 probes were sequentially displayed to test recognition. The left/right-hand key assignment for yes/no answers was varied. No SPoARC effect was observed. However, as all previous SPoARC experiments had used short lists and closed sets, it was not possible to know if this absence of SPoARC was due to the open set feature or the length of the lists. A second experiment was thus run using open sets and short 5-word lists, which do not necessitate EM to be remembered. A SPoARC effect was observed indicating that Experiment 1 result was due to the involvement of supra-span lists and that SPoARC effects do not extend to EM with open sets. Experiment 2 also enabled us to generalise the SPoARC effect to open sets in WM for the first time.     

La gestion des émotions et ses déficits,chez les personnes atteintes de douleur chronique : une revue systématisée des études relatives à l’alexithymie, à l’intelligence émotionnelle, à la régulation émotionnelle et au coping

The goal of this review is to synthesize the data of scientific literature on emotional management and its deficits in chronic pain. We used terms referenced in databases and MesH terms (of the United States National Library of Medicine) to perform a literature search in a powerful online search engine (EBSCOhost research databases). Four hundred and forty-nine papers, taken from international reviews and published of 1994 (because it is in the middle of the 1990s that this theme begins to be handle) to the end of January, 2015, are identified by a total 5 electronic databases with predefined keywords about emotions and chronic pain. Forty-six of which met the inclusion criteria, according to their title, their summary and their complete text. The findings suggest that some emotional management strategies and its deficits can maintain a vicious circle of negative emotional states with physiological and psychopathological consequences. Several studies show that alexithymia, emotional ambivalence and emotional suppression have a deleterious impact on pain, emotional distress (depression, anxiety) and disability. In spite of some contradictions concerning the nature of this effect (sensory or affective pain intensity or even duration of pain), it seems that alexithymia is a major variable implied in chronic pain. Inversely, experiential acceptance has a beneficial effect on psychological distress (depression, anxiety and stress). Emotional disclosure (of stressful or traumatic events) can decrease pain intensity but not disability and mental health. Likewise, emotional expression in daily life seems beneficial, but when the expression of the positive and negative feelings are distinguished, emotional expression of negative feelings increases pain, disability and distress. The whole of these findings emphasize the need to further research about emotional management in chronic non-cancer pain. It is necessary to identify and control the source of potential bias. Some hypotheses have been proposed to explain these findings. In the future, it would be interesting to use a multifactorial approach to investigate the interactions between various processes of emotional management in chronic pain patients.     

Can Facebook Informational Use Foster Adolescent Civic Engagement?

The findings on the association between Social Networking Sites and civic engagement are mixed. The present study aims to evaluate a theoretical model linking the informational use of Internet‐based social media (specifically, Facebook) with civic competencies and intentions for future civic engagement, taking into account the mediating role of civic discussions with family and friends and sharing the news online. Participants were 114 Italian high school students aged 14–17 years (57 % boys). Path analysis was used to evaluate the proposed theoretical model. Results showed that Facebook informational use was associated with higher levels of adolescent perceived competence for civic action, both directly and through the mediation of civic discussion with parents and friends (offline). Higher levels of civic competencies, then, were associated with a stronger intention to participate in the civic domain in the future. Our findings suggest that Facebook may provide adolescents with additional tools through which they can learn civic activities or develop the skills necessary to participate in the future.
