Stratégies de contrôle adaptatives au fil de l’âge adulte et rôle des ressources cognitives dans leur déploiement

The current study investigated the age-related differences in control strategies deployment, and examined the relations of control strategies with indicators of well-being and cognitive efficiency. Eighty-five participants aged from 18 to 93 years old completed measures of control strategies and anxiety, and were administered several cognitive tests designed to assess processing speed, reasoning and episodic memory. Results showed that (1) middle-aged individuals use more control strategies based on emotional regulation and goal disengagement than younger and older individuals, (2) individuals who deploy more control strategies focused on emotions report lower levels of anxiety, and (3) cognitive resources moderate the relation between age and control strategies deployment. That is, although increased age is associated with lower deployment of control strategies, the current project showed that age effects in control strategies were weaker for people with higher levels of cognitive resources than for people with lower levels of cognitive resources.     

Central load reduces peripheral processing: Evidence from incidental memory of background speech

Is there a trade‐off between central (working memory) load and peripheral (perceptual) processing? To address this question, participants were requested to undertake an n‐back task in one of two levels of central/cognitive load (i.e., 1‐back or 2‐back) in the presence of a to‐be‐ignored story presented via headphones. Participants were told to ignore the background story, but they were given a surprise memory test of what had been said in the background story, immediately after the n‐back task was completed. Memory was poorer in the high central load (2‐back) condition in comparison with the low central load (1‐back) condition. Hence, when people compensate for higher central load, by increasing attentional engagement, peripheral processing is constrained. Moreover, participants with high working memory capacity (WMC) – with a superior ability for attentional engagement – remembered less of the background story, but only in the low central load condition. Taken together, peripheral processing – as indexed by incidental memory of background speech – is constrained when task engagement is high.     

Doubling‐down on deprivation: Using latent profile analysis to evaluate an age‐old assumption in relative deprivation theory

Theorists have long argued that two forms of relative deprivation exist: individual‐based relative deprivation (IRD) whereby a person feels deprived relative to other individuals and group‐based relative deprivation (GRD) whereby a person feels his/her ingroup is deprived relative to other groups. Combinations of IRD and GRD are therefore assumed to produce four response profiles: (i) high on IRD and GRD (i.e. ‘doubly deprived’); (ii) high on IRD, low on GRD; (iii) low on IRD, high on GRD; or (iv) low on IRD and GRD. The existence of these profiles, however, has never been assessed. We address this oversight by using latent profile analysis to identify distinct response patterns to measures of IRD and GRD. Across two studies, we found no support for this typology, nor the oft‐assumed doubly deprived profile. Rather, response patterns showed moderate levels of IRD across discrete profiles accompanied by considerable variability in GRD.     

Skeptical Appeal: The Source‐Content Bias

Radical skepticism is the view that we know nothing or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an interaction between two factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e., that something is not the case) than when it is positive (i.e., that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology.     

The relationship of self-talk frequency to communication apprehension and public speaking anxiety

This research examines how self-talk is related to the nature and prevalence of communication apprehension and public speaking anxiety. In Study 1, we examined the relationship between general communication apprehension (CA) and the frequency and nature of general self-talk. Results showed that higher CA scores were associated with more frequent self-critical self-talk than lower CA scores. In Study 2, we examined how self-talk pertaining to the preparation for an upcoming speech related to public speaking anxiety. Results showed that self-critical and social-assessing self-talk were positively related to people’s anxiety scores, whereas self-reinforcing self-talk was negatively associated with their anxiety. Implications of these results for the management of public speaking anxiety are discussed.     

Life seems different with you around: Differential shifts in cognitive appraisal in the mere presence of others for neuroticism and impression management

How does mere social presence affect cognitive processes? The extant literature has focused on the impact of social presence on cognitive resources. The present study extends this work by focusing on the positivity of cognitive appraisal. Building on recent findings it was predicted that the traits neuroticism and impression management will differentially moderate the effect, such that neuroticism will be associated with a negative shift in appraisal, and impression management with a positive shift. In an experiment, participants (N = 158) formed evaluations of life events either alone or in social presence. The results supported the predictions. The findings advance the knowledge about the effect of social presence on cognition, and about the role of personality in moderating responses in public social contexts.     

Anxiety symptom interpretation and performance expectations in high-anxious,low-anxious,defensive high-anxious and repressor individuals

To date, no research has investigated score predictions and anxiety interpretation in high-anxious, low-anxious, defensive high-anxious and repressor individuals. This study examined Eysenck’s (1997) predictions for cognitive biases on future performance expectations in all four groups. This study was conducted in an ecologically-valid sporting environment. Competitive shooters completed the Marlowe–Crowne Social Desirability Scale and the Sport Anxiety Scale prior to a major competition. Percentile splits identified the four defensiveness/anxiety groups. The modified Competitive Sport Anxiety Inventory-2 was used to assess the intensity and direction of anxiety prior to competition. Participants predicted their expected shooting score. The hypothesis that repressors would interpret their anxiety as more facilitative to performance compared to low-anxious individuals was partially supported. Repressors were more optimistic in their performance prediction in contrast to defensive high-anxious performers who, in turn, were more pessimistic compared to the other two groupings. High-anxious performers, contrary to predictions, demonstrated optimism in their future performance. The findings of this study corroborate the theoretical predictions and the evidence from previous studies with sport performers. Future research should continue to investigate the influence of cognitive biases on performance predictions in sporting environments using Weinberger et al.’s classifications.     

Career adaptability profiles and their relationship to adaptivity and adapting

Research on career adaptability predominantly uses variable-centered approaches that focus on the average effects in terms of the predictors and outcomes within a given sample. Extending this research, the present paper used a person-centered approach to determine whether subgroups with distinct adaptability profiles in terms of concern, control, curiosity and confidence can be identified. We also explored the relationship between the various adaptability profiles and adapting (career planning, career decision-making difficulties, career exploration, and occupational self-efficacy beliefs) and adaptivity (core self-evaluations and proactivity). Using latent profile analysis, we found distinct adaptability profiles among 350 German university students. Students with different profiles differed significantly in their levels of adapting. This finding was confirmed in a second study of 1226 students selected from the same population. In both samples, the adaptability profiles differed mainly in terms of their adaptability levels but not their shape. Moreover, in both samples, the students whose profiles indicated generally higher adaptability showed more adapting compared with the students whose profiles indicated generally lower adaptability. Study 2 also showed that students with higher-adaptability profiles showed significantly higher adaptivity. The results suggest that level effects dominate adaptability profiles, implying the existence of a general adaptability factor within university students that is meaningfully related to adapting and adaptivity.     

The impact of concurrent visual feedback on coding of on-line and pre-planned movement sequences

The purpose of this study was to determine the extent to which participants could effectively switch from on-line (OL) to pre-planned (PP) control (or vice versa) depending on previous practice conditions and whether concurrent visual feedback was available during transfer testing. The task was to reproduce a 2000 ms spatial–temporal pattern of a sequence of elbow flexions and extensions. Participants were randomly assigned to one of two practice conditions termed OL or PP. In the OL condition the criterion waveform and the cursor were provided during movement production while this information was withheld during movement production for the PP condition. A retention test and two effector transfer tests were administered to half of the participants in each acquisition conditions under OL conditions and the other half under PP conditions. The mirror effector transfer test required the same pattern of muscle activation and limb joint angles as required during acquisition. The non-mirror transfer test required movements to the same visual–spatial locations as experienced during acquisition. The results indicated that when visual information was available during the transfer tests performers could switch from PP to OL. When visual information was withdrawn, they shifted from the OL to the PP-control mode. This finding suggests that performers adopt a mode of control consistent with the feedback conditions provided during testing.
