Incertitudes au cours de la carrière et construction des perspectives temporelles

The increasing uncertainty context, in which individuals' professional paths are taking form today, is the occasion to a critical renewal of career course analysis models. In the first part of the article, we argue with the model propounded by Power and Rothausen (2003), which aims to analyse and support mid-career professional orientation behaviours, by extending the Super's career maintenance stage. We partly break free with them, defending the conception of an active socialisation, which analysis of orientation behaviours is based on the conjoined study of temporal perspectives and of exchanges between life domains. This point of view is supported by results from a research dealing with future temporal perspectives reconstruction processes of individuals confronted with the unemployment uncertainty. They show that individuals do not project in the future only by striving for yielding “employable”. Their projects do not only result from the rational control of the information related to the anticipated professional environment. Ascribed to peculiar paths, those projects summon up processes of values confrontation and comparisons with others, in the plurality of individuals' life fields.     

不同背景噪音干扰下的数字短时记忆研究

以三种类型(交通噪音、生活噪音、舒缓乐音)三种声级(40.7dBA、56.4dBA、73.3dBA)的环境噪音作为无关声音刺激,考察其对数字短时记忆广度和Sternberg任务的影响,发现:(1)背景噪音的不同对个体数字短时记忆广度影响没有显著差异;(2)背景噪音声级的不同对个体删除极端数值后正确反应的反应时及对“极错总比率”都有显著的影响;(3)对于删除极端数值后的正确反应来说,在不同背景噪音存在下,随着记忆集的增大,反应时仍然呈直线上升趋势。     

The effect of long-term working memory through personalization applied to free recall: Uncurbing the primacy-effect enthusiasm

In this study, a personalization method (Guida, Tardieu, & Nicolas, European Journal of Cognitive Psychology, 21: 862–896 2009) was applied to a free-recall task. Fifteen pairs of words, composed of an object and a location, were presented to 93 participants, who had to mentally associate each pair and subsequently recall the objects. A 30-s delay was introduced on half of the trials, the presentation rate was manipulated (5 or 10 s per item), and verbal and visuospatial working memory tests were administered to test for their effects on the serial curve. Two groups were constituted: a personalized group, for whom the locations were well-known places on their university campus, and a nonpersonalized group, for whom the locations did not refer to known places. Since personalization putatively operationalizes long-term working memory (Ericsson & Kintsch, Psychological Review, 102: 211–245 1995)—namely, the capacity to store information reliably and rapidly in long-term memory—and if we take a dual-store approach to memory, the personalization advantage would be expected to be greater for pre-recency than for recency items. Overall, the results were compatible with long-term working memory theory. They contribute to validating the personalization method as a methodology to characterize the contribution of long-term memory storage to performance in working memory tasks.     

Abatement of intractable vocal stereotypy using an overcorrection procedure

We conducted a series of reversals to compare the effects of four different treatments on vocal stereotypy emitted by a 7‐year‐old boy with autism. The results showed that (1) the level of vocal stereotypy decreased during exposure to matched stimulation but returned to high levels immediately upon its removal; (2) stereotypy did not significantly decrease during differential reinforcement of other behavior; and (3) contingent withdrawal of movies and music (i.e., response cost) was only moderately effective. However, positive practice overcorrection decreased vocal stereotypy by clinically significant levels. Further, when differential reinforcement of engagement in a Lego^® building task was implemented, the level of engagement was significantly higher when positive practice overcorrection was in place than when overcorrection was withdrawn.

EUTHYPHRO AND THE GOODNESS OF GOD INCARNATE

A familiar problem is here viewed from an unfamiliar angle. The familiar problem is the Euthyphro dilemma: if God wills something because it is good, then goodness is independent of God, so God becomes, morally speaking, de trop. On the other hand, if something is good because God wills it, then, given the absence of constraint on what God may will, moral truths are – counterintuitively – contingent. An examination of the kinds of necessity and possibility at work in this conundrum leads us to the most promising solution: there is a metaphysical connection between God and goodness. What he wills is an expression of his nature. But (and this is the unfamiliar angle), that solution now poses an acute problem for an understanding of the Incarnation. For if God is constitutive of goodness, and Christ is God incarnate, then Christ is constitutive of goodness. But Christ, as a human, is subject to external moral evaluation and obligation, which entails that he is not constitutive of goodness. This metaethical difficulty is not easily met by the usual strategies by which Christ is understood to have two natures. Reflection on our moral relations to our past selves, however, suggests a way forward.     

Neural dissociation of phonological and visual attention span disorders in developmental dyslexia: FMRI evidence from two case reports

A dissociation between phonological and visual attention (VA) span disorders has been reported in dyslexic children. This study investigates whether this cognitively-based dissociation has a neurobiological counterpart through the investigation of two cases of developmental dyslexia. LL showed a phonological disorder but preserved VA span whereas FG exhibited the reverse pattern. During a phonological rhyme judgement task, LL showed decreased activation of the left inferior frontal gyrus whereas this region was activated at the level of the controls in FG. Conversely, during a visual categorization task, FG demonstrated decreased activation of the parietal lobules whereas these regions were activated in LL as in the controls. These contrasted patterns of brain activation thus mirror the cognitive disorders’ dissociation. These findings provide the first evidence for an association between distinct brain mechanisms and distinct cognitive deficits in developmental dyslexia, emphasizing the importance of taking into account the heterogeneity of the reading disorder.     

Supervisors' upward exchange relationships and subordinate outcomes: testing the multilevel mediation role of empowerment

This study empirically examined the proposition that supervisors' exchange relationships with their own supervisors (i.e., leader-leader exchange, or LLX) are related to their subordinates' work-related outcomes through 3 mechanisms: (a) leaders modeling their LLX to develop and maintain their exchange relationships with their subordinates (i.e., leader-member exchange, or LMX), (b) motivating the team and its members, captured by team and individual empowerment, and (c) facilitating the relationships between LMX and individual outcomes. Analyses of multisource and lagged data from 104 team supervisors and 577 subordinates showed that LMX mediated the positive relationship of LLX on subordinates' individual empowerment. Furthermore, team empowerment and individual empowerment sequentially mediated the positive relationships between LLX and subordinates' job satisfaction and job performance. The authors also found that the indirect relationships of LMX with job satisfaction and job performance via individual empowerment were stronger when LLX was higher. Theoretical and practical implications of these findings are discussed.     

Biased extensive measurement: The general case

We develop a theory of biased extensive measurement which allows us to prove the existence of a ratio-scale without transitivity of indifference and with a property of homothetic invariance weaker than independence. These representations, which cover the cases of interval orders and of semiorders, reveal a unique biasing function smaller or equal to 1 that distorts extensive measurement and explains departures from its standard axioms. We interpret this biasing function as characterizing the qualitative influence of the underlying measurement process and we show that it induces a proportional indifference threshold.     

Disrupted attentional learning in high schizotypy: Evidence of aberrant salience

The relationship between learned variations in attention and schizotypy was examined in two experiments. In Experiment 1, participants low on a negative subscale of schizotypy exhibited an explicit bias in overt attention towards stimuli that were established as predictive of a trial outcome, relative to stimuli that were irrelevant. The same participants also showed a bias in learning about these stimuli when they presented in a novel context. Neither of these effects was observed in participants high in schizotypy. In Experiment 2, participants low on the negative subscale of schizotypy exhibited faster reaction times towards a target that was cued by a stimulus that had a history of predictive validity relative to a stimulus that had a history of irrelevance. Again, this effect was not present in participants high in schizotypy. These results imply a disruption in the normal allocation of attention to cues that have predictive significance in schizotypy.     

The Stroop test: A developmental study in a French children sample aged 7 to 12 years

The Stroop test is a commonly used task in psychology to assess executive function and more specifically inhibition. International studies consistently show improved Stroop task performance with age, whereas available French normative data displays the opposite pattern, with poor clinical sensibility (Albaret & Migliore, 1999). To provide an alternative and useful Stroop test for children, we examined developmental data based on a well-known French protocol validated in adult (GREFEX study group, 2001). The three-standard conditions of the Stroop task (i.e. naming, reading and interference) were administered to 120 typically developing school children (7–12 years), while taking into account the effects of gender, parental educational level and intelligence (both crystallized and fluid intelligence, as measured by the Wechsler intelligence scale). The time to complete each condition (in seconds) was recorded, as well as the number of uncorrected and corrected errors. Results show a continuous increase of performance in “reading” and “naming” control conditions between 7 and 12 years, suggesting an improvement in the lexical access speed and the automation of decoding abilities during reading. Most importantly, a significant reduction of time Stroop effect with age was found (difference between interference and naming conditions), but no interaction with gender. Stroop performances are related to fluid intelligence once age is statistically controlled, but not to parental educational level. The developmental pattern found from the Stroop GREFEX version is consistent with international data and more broadly with executive function and inhibition development. These findings open the prospect of useful normative standardization of this task, with valuable clinical applications perspectives.
