Increasing the salience of fluency cues does not reduce the recognition memory impairment in Alzheimer's disease!

In Alzheimer's disease (AD), it is now well established that recollection is impaired from the beginning of the disease, whereas findings are less clear concerning familiarity. One of the most important mechanisms underlying familiarity is the sense of familiarity driven by processing fluency. In this study, we attempted to attenuate recognition memory deficits in AD by maximizing the salience of fluency cues in two conditions of a recognition memory task. In one condition, targets and foils have been created from the same pool of letters (Overlap condition). In a second condition, targets and foils have been derived from two separate pools of letters (No‐Overlap condition), promoting the use of letter‐driven visual and phonetic fluency. Targets and foils were low‐frequency words. The memory tasks were performed by 15 patients with AD and 16 healthy controls. Both groups improved their memory performance in the No‐Overlap condition compared to the Overlap condition. Patients with AD were able to use fluency cues during recognition memory as older adults did, but this did not allow to compensate for dysfunction of recognition memory processes.     

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.     

Therapeutic Creativity,Complexity, and Ed Tronick’s Dyadic Expansion of Consciousness

Ed Tronick’s research on interaction and infant development has greatly inspired clinicians. His new focus on the infant resulted in changes in ways of thinking about infant development and in the psychotherapeutic methods used with very young infants and their caregivers. The mutual regulation model (MRM) gave empirical support to clinical observations and later gave rise to the Still Face paradigm. The MRM model offers a theoretical framework for developing detailed mother–infant therapeutic capacities while it raises major theoretical questions on the manners in which the infant’s personal inner world develops. Considering the parent–infant dyad as a whole underscores the need to address infant and parental characteristics together, integrating development itself as an important force for mental health. This suggests that the infant is both a system in itself, capable of self-organization, and a part of a cocreating system with his or her partner, for example in the dyadic organization of states. It could mean that analysts should probably be both modest and brazen in their therapeutic interventions, taking advantage, as clinicians of knowledge based on the latest scientific research, linked to experience and culturally appropriate socially sensitive interventions. In this way, they may provide positively enriched experiences, working through problematic negative emotions that our patients will keep and use in their own creative way.     

Episodic encoding in normal aging: attentional resources hypothesis extended to musical material

The goal of the present study was to examine age-related changes in musical episodic memory for novel tunes. This was conducted by manipulating the encoding condition in a recognition paradigm. After receiving memory instructions (intentional condition), older and younger participants obtained equivalent hits. In contrast, when intentional encoding was accompanied by a dancing judgment (dancing + intentional condition), the recognition performance of the older persons was severely impaired. Impaired recognition was also found when participants only judged the excerpts without being instructed to memorize them (dancing judgment condition). Although older participants demonstrated a preserved ability to perform the dancing judgment on its own, this ability was not optimal and likely precluded the initiation of more elaborate encoding strategies. These results suggest that asking older persons to divide their attention in the study phase reduces the quality of their musical encoding. Given this extension to musical material, we discuss the notion that the age-related attentional resource decline appears to be domain-general rather than specific to verbal material.     

Dynamic perception in chess

The present study examines the dynamic aspects of perceptual processes in expert chess players. This topic is approached in terms of the anticipation processes carried out by experienced players during the encoding of chess positions. The aim of the first experiment, which used a short-term comparison task, was to stress the role of anticipation, which allows expert players to focus their attention on the area of the studied position where they expect the likely standard move to occur. The second experiment used a long-term recognition task. The results showed that expert players made many false recognitions on the new positions that could be expected from the positions presented in the preliminary study phase. Taken together, the results of the two experiments highlight the anticipatory component of expert perception.     

Effect of temporal constraints on hemispheric asymmetries during spatial frequency processing

Studies on functional hemispheric asymmetries have suggested that the right vs. left hemisphere should be predominantly involved in low vs. high spatial frequency (SF) analysis, respectively. By manipulating exposure duration of filtered natural scene images, we examined whether the temporal characteristics of SF analysis (i.e., the temporal precedence of low on high spatial frequencies) may interfere with hemispheric specialization. Results showed the classical hemispheric specialization pattern for brief exposure duration and a trend to a right hemisphere advantage irrespective of the SF content for longer exposure duration. The present study suggests that the hemispheric specialization pattern for visual information processing should be considered as a dynamic system, wherein the superiority of one hemisphere over the other could change according to the level of temporal constraints: the higher the temporal constraints of the task, the more the hemispheres are specialized in SF processing.
