Cerebral Asymmetry and Reading Performance: Effect of Language Lateralization and Hand Preference

Abstract

We propose an alternative approach aimed at relating cerebral asymmetry to reading ability: the joint consideration of language lateralization and hand preference. Specifically, we studied whether children with dominance for language and control of the preferred hand lateralized to the same hemisphere (convergent cerebral organization) were better readers than were children with these processes lateralized to different hemispheres (nonconvergent organization). Eighty children, selected on the basis of the combination of these factors, were assessed using a set of reading tasks. The main finding was that subjects with convergent cerebral organization were superior in reading speed, reading accuracy, and reading comprehension.     

From mental strain to burnout

This study examines the relationships between burnout and short-term consequences of mental strain within and outside human services professions, at the same time contributing to the understanding of the development of burnout as a long-term effect of impairing work and job design. A total of 294 German employees working in human services (N = 149) and industrial production (N = 145) completed the Oldenburg Burnout Inventory (OLBI) and four scales measuring short-term consequences of mental strain. Results of factor analyses confirmed that the elements of the OLBI's two-factor structure—exhaustion and disengagement—are distinct from a range of impairing short-term consequences of mental strain. In addition, structural equation modelling showed that each burnout dimension is differentially related to specific short-term consequences of strain: Exhaustion is primarily related to mental fatigue, whereas disengagement is primarily related to satiation and the experience of monotony. The findings did not differ substantially for the two occupational groups. Burnout, as a long-term consequence of impairing mental strain, is distinct from and presumably temporally-causally related to specific impairing short-term consequences of mental strain, which, in turn, can be attributed to inadequate job design.     

Be water: Direct and indirect relations between perceived emotional intelligence and subjective well‐being

Trait emotional intelligence (TEI) has been shown to have predictive capacity for certain dimensions of adaptation, such as life satisfaction and affectivity. The Trait Meta Mood Scale (TMMS), based on the EI ability model, has been shown to have predictive capacity for subjective well‐being through its three factors (attention, clarity, and emotional repair), but little is known about the mediating role played by these dimensions, both among themselves and in relation to other variables. The aim of the present study was to analyse the direct and indirect relationships between the TMMS factors and subjective well‐being dimensions, using structural equation modelling, also including self‐efficacy in the model as a mediator of these relationships. Attention was found to have a negative effect on subjective well‐being, which was inhibited when clarity and repair were included as mediators. Self‐efficacy played a major role since it increased the positive effect of clarity and repair on subjective well‐being. This study provides evidence of the advantage of using the TMMS factors separately and of studying their mediational role in order to better understand the processes underlying the manner in which TEI influences subjective well‐being.     

Voluntarily-generated unimanual preparation is associated with stopping success: evidence from LRP and lateralized mu ERD before the stop signal

According to the race models of the stop-signal paradigm, stopping success (successful vs. unsuccessful stopping) is attributed to the finishing times of a go and a stop process. In addition to those factors involving processing times, in the present study we sought to use electrophysiological measures to find factors involving activations that could affect stopping success. We hypothesized that voluntarily-generated unimanual preparation would be a factor. To assess voluntarily-generated unimanual preparation in the stop-signal paradigm, we used a selective-stopping task without any precue. The selective-stopping task also allowed us to assess reaction times (RTs) even when stopping was successful. We demonstrated shorter RTs in signal-respond (i.e. unsuccessful stopping) than in signal-inhibit (successful stopping) trials, as is predicted by the race models. More importantly, we also demonstrated different pre-signal lateralized readiness potentials between the two types of trials and larger lateralized mu ERD in signal-respond than in signal-inhibit trials, suggesting that voluntarily-generated unimanual preparation affects stopping success. In addition to what is described in the race models of the stop-signal paradigm, the present results therefore demonstrated measures of pre-signal activations that could influence stopping success.     

Theory of mind and its relationship with executive functions and emotion recognition in borderline personality disorder

Impaired social cognition has been claimed to be a mechanism underlying the development and maintenance of borderline personality disorder (BPD). One important aspect of social cognition is the theory of mind (ToM), a complex skill that seems to be influenced by more basic processes, such as executive functions (EF) and emotion recognition. Previous ToM studies in BPD have yielded inconsistent results. This study assessed the performance of BPD adults on ToM, emotion recognition, and EF tasks. We also examined whether EF and emotion recognition could predict the performance on ToM tasks. We evaluated 15 adults with BPD and 15 matched healthy controls using different tasks of EF, emotion recognition, and ToM. The results showed that BPD adults exhibited deficits in the three domains, which seem to be task‐dependent. Furthermore, we found that EF and emotion recognition predicted the performance on ToM. Our results suggest that tasks that involve real‐life social scenarios and contextual cues are more sensitive to detect ToM and emotion recognition deficits in BPD individuals. Our findings also indicate that (a) ToM variability in BPD is partially explained by individual differences on EF and emotion recognition; and (b) ToM deficits of BPD patients are partially explained by the capacity to integrate cues from face, prosody, gesture, and social context to identify the emotions and others' beliefs.     

Experiencing extinction within a task makes nonextinguished information learned within a different task context-dependent

In two experiments with rats, we analyzed the effect of experiencing extinction in one task on the context specificity of a new association learned within a different task. Rats were trained to run in a runway for water in Task 1, and received taste aversion conditioning in Task 2 (the tasks were reversed in Exp. 2). Half of the rats received conditioning and extinction of Task 1 in Context A, whereas the other half received no extinction. Then all animals received training in the alternate task in Context B, prior to testing in Context C. When they were tested in Context C, Task 2 performance was attenuated if Task 1 had been extinguished prior to Task 2. These results are similar to those we have reported in humans, and consistent with the idea that extinction prompts attention to contexts, regardless of whether or not the contexts were involved in extinction.     

Relational and item-specific influences on generate–recognize processes in recall

The generate–recognize model and the relational–item-specific distinction are two approaches to explaining recall. In this study, we consider the two approaches in concert. Following Jacoby and Hollingshead (Journal of Memory and Language 29:433–454, 1990), we implemented a production task and a recognition task following production (1) to evaluate whether generation and recognition components were evident in cued recall and (2) to gauge the effects of relational and item-specific processing on these components. An encoding task designed to augment item-specific processing (anagram-transposition) produced a benefit on the recognition component (Experiments 1–3) but no significant benefit on the generation component (Experiments 1–3), in the context of a significant benefit to cued recall. By contrast, an encoding task designed to augment relational processing (category-sorting) did produce a benefit on the generation component (Experiment 3). These results converge on the idea that in recall, item-specific processing impacts a recognition component, whereas relational processing impacts a generation component.
