Relative category-specific preservation in semantic dementia? Evidence from 35 cases

Category-specific deficits have rarely been reported in semantic dementia (SD). To our knowledge, only four previous studies have documented category-specific deficits, and these have focused on the living versus non-living things contrast rather than on more fine-grained semantic categories. This study aimed to determine whether a category-specific effect could be highlighted by a semantic sorting task administered to 35 SD patients once at baseline and again after 2 years and to 10 Alzheimer’s disease patients (AD). We found a relative preservation of fruit and vegetables only in SD.This relative preservation of fruit and vegetables could be considered with regard to the importance of color knowledge in their discrimination. Indeed, color knowledge retrieval is known to depend on the left posterior fusiform gyrus which is relatively spared in SD. Finally, according to predictions of semantic memory models, our findings best fitted the Devlin and Gonnerman’s computational account.     

From stimulus-driven to appraisal-driven attention: Towards differential effects of goal relevance and goal relatedness on attention?

The Component Process Model posits that attention is appraisal-driven rather than stimulus-driven and that the appraisal of relevance is of critical importance in such a mechanism. This means that any stimulus can attract attention or not depending on how relevant it is appraised. This hypothesis was tested in an implicit border similarity judgement task, in which thirsty participants were presented with bottles and vases that were respectively very relevant and weakly relevant to their goal to quench their thirst. These stimuli were also presented to quenched participants for whom none of the stimuli was relevant. The findings support the idea that our attention is more likely to be appraisal-driven than stimulus-driven, since bottles produced an attentional interference in thirsty participants only. It was also observed that, even if vases were judged weakly relevant by thirsty participants, they produced an attentional interference compared to empty stimuli, which was not the case in the quenched participants group. The concept of goal relatedness was proposed as an explanation for this result, and methodological implications were also discussed.

Level of emotional awareness in the general French population: Effects of gender,age, and education level

The Levels of Emotional Awareness Scale (LEAS) developed by Lane et al. ( 1990 1990) measures the ability of a subject to discriminate his or her own emotional state and that of others. The scale is based on a cognitive‐developmental model in which emotional awareness increases in a similar fashion to intellectual functions. Because studies performed using North American and German populations have demonstrated an effect of age, gender, and level of education on the ability to differentiate emotional states, our study attempts to evaluate whether these factors have the same effects in a general French population. 750 volunteers (506 female, 244 male), who were recruited from three regions of France (Lille, Montpellier, Paris), completed the LEAS. The sample was divided into five age groups and three education levels. The results of the LEAS scores for self and others and the total score showed a difference in the level of emotional awareness for different age groups, by gender and education level. A higher emotional level was observed for younger age groups, suggesting that emotional awareness depends on the cultural context and generational societal teachings. Additionally, the level of emotional awareness was higher in women than in men and lower in individuals with less education. This result might be explained by an educational bias linked to gender and higher education whereby expressive ability is reinforced. In addition, given the high degree of variability in previously observed scores in the French population, we propose a standard based on our French sample.     

Culture of honour theory and social anxiety: Cross-regional and sex differences in relationships among honour-concerns,social anxiety and reactive aggression

According to the Appraisal-Tendency Framework (Han, Lerner, & Keltner, 2007), certainty-associated emotions increase risk taking compared with uncertainty-associated emotions. To date, this general effect has only been shown in static judgement and decision-making paradigms; therefore, the present study tested the effect of certainty on risk taking in a sequential decision-making task. We hypothesised that the effect would be reversed due to the kind of processing involved, as certainty is considered to encourage heuristic processing that takes into account the emotional cues arising from previous decisions, whereas uncertainty leads to more systematic processing. One hundred and one female participants were induced to feel one of three emotions (film clips) before performing a decision-making task involving risk (Game of Dice Task; Brand et al., 2005). As expected, the angry and happy participants (certainty-associated emotions) were more likely than the fearful participants (uncertainty-associated emotion) to make safe decisions (vs. risky decisions).     

Pleasant emotional induction broadens the visual world of young children

These experiments aimed at studying the influence of emotional context on global/local visual processing in children. Children 5 years old, known to present an immature global visual bias, and 8 years old, known to pay attention predominantly to global information, were placed in either a neutral or pleasant emotional context and subsequently presented with a global/local visual judgement task. As with previous findings for adults, both age groups presented a pronounced perceptual bias toward global information following exposure to emotionally pleasant pictures. Interestingly, younger children, who do not present a global bias during the neutral exposure, presented the same preference for global information as older children when exposed to the pleasant context. These findings indicate that emotion may strongly affect visual perception in children, with important implications for educational practice and models of cognition.     

Psychological Predictors of Career Planning among Active Elite Athletes: An Application of the Social Cognitive Career Theory

The present study examines mechanisms underlying career planning among athletes in the context of sport career termination. The contribution of conscientiousness to athletes' career planning was investigated among 180 active athletes (88 females, 92 males; M_age = 20.36) by applying the social cognitive career theory (SCCT). Bootstrap analyses, performed at both broad and facet-level, revealed that conscientious individuals are more likely to plan for their future career because they set higher goals and are more confident in their capacity to plan their future career. Implications for practice are discussed in relation to intervention that could induce career planning among athletes.     

Over-estimation in numerosity estimation tasks: More than an attentional bias?

Over- and under-estimation have been observed in numerosity estimation and approximate arithmetic tasks. Two different models have been proposed to account for these reverse patterns of performance: 1) the bi-directional mapping account (Crollen, Castronovo, & Seron, 2011); 2) the operational momentum hypothesis (McCrink, Dehaene, & Dehaene-Lambertz, 2007). Our study was designed to examine whether the operational momentum could account for the over-estimation found in numerosity estimation tasks. To this aim, a series of 3 experiments involving a symbolic to non-symbolic numerical mapping and a rightward or leftward displacement along the mental number line were designed. Over-estimation was observed in these three tasks irrespective of the direction and size of the displacement to be done on the mental number line. These results thus clearly demonstrated that overestimation was not merely due to an attentional bias, but rather relied on the cognitive operation of mapping two differently scaled numerical representations.     

TRANSITIVITY OF ODOR PREFERENCES: CONSTANT AND PARTICULARITIES IN HEDONIC PERCEPTION

Transitivity of preferences has been investigated for a long time in decision‐making. In the field of perception, the pleasantness of odors raises several questions related to individual versus cultural or universal preferences and the existence of a classification in a delimited hedonic space. The aim of this study was to test transitivity in olfactory hedonicity using a first panel of 10 mixed odors and a second panel of 10 odors from a delimited floral category. Data were collected by paired comparisons in a two‐alternative forced choice. Results in both panels showed a strong transitivity for each participant leading to a linear range of 10 odors classified by preference. However, ranges varied from one participant to another and the mean preferences of the group did not allow one to infer individual's hedonic classification of odors. Moreover, the individual classification appeared stable over time and undisturbed by odorant distractors. These findings suggest that humans have considerable ability to classify odors hedonically as a model of individual preferences in a sensory space usually considered to be more involved in affective/emotional states than in cognitive performances.
