Enhanced conflict-driven cognitive control by emotional arousal,not by valence

Emotion is widely agreed to have two dimensions, valence and arousal. Few studies have explored the effect of emotion on conflict adaptation by considering both of these, which could have dissociate influence. The present study aimed to fill the gap as to whether emotional valence and arousal would exert dissociable influence on conflict adaptation. In the experiments, we included positive, neutral, and negative conditions, with comparable arousal between positive and negative conditions. Both positive and negative conditions have higher arousal than neutral ones. In Experiment 1, by using a two-colour-word Flanker task, we found that conflict adaptation was enhanced in both positive and negative contexts compared to a neutral context. Furthermore, this effect still existed when controlling stimulus–response repetitions in Experiment 2, which used a four-colour-word Flanker task. The findings suggest emotional arousal enhances conflict adaptation, regardless of emotional valence. Thus, future studies should consider emotional arousal when studying the effect of emotion on conflict adaptation. Moreover, the unique role of the emotional context in conflict-driven cognitive control is emphasised.     

The impact of post-learning sleep vs. wakefulness on recognition memory for faces with different facial expressions

A beneficial effect of sleep after learning, compared to wakefulness, on memory formation has been shown in many studies using a variety of tasks. However, none of these studies has specifically addressed recognition memory for faces so far. The recognition of familiar faces, together with the extraction of emotional information from facial expression, is a fundamental cognitive skill in human everyday life, for which specific neural systems and mechanisms of processing have been developed. Here, we investigated the role of post-learning sleep for later recognition memory for neutral, happy, and angry faces. Twelve healthy subjects, after judging the emotional valence of the faces in the evening (learning phase), either slept normally in the subsequent night, with sleep recorded polysomnographically (sleep condition), or remained awake (wake condition) according to a cross-over design. Recognition testing took place in the second evening after learning, i.e. after a further night of regular sleep spent at home. Sleep after learning, compared to wakefulness, enhanced memory accuracy in recognition memory. This effect was independent of the emotional valence of facial expression. The response criterion at recognition testing did not differ between sleep and wake conditions. The amount of non rapid eye movement (NonREM) sleep during post-learning sleep correlated positively with memory accuracy at recognition testing, while time in REM sleep was associated with a speeded responding to the learned faces. Results suggest that face recognition, despite its dependence on specialized brain systems, nevertheless relies on the general neural mechanisms of sleep-associated memory consolidation.     

Intact implicit learning in autism spectrum conditions

Individuals with autism spectrum condition (ASC) have diagnostic impairments in skills that are associated with an implicit acquisition; however, it is not clear whether ASC individuals show specific implicit learning deficits. We compared ASC and typically developing (TD) individuals matched for IQ on five learning tasks: four implicit learning tasks—contextual cueing, serial reaction time, artificial grammar learning, and probabilistic classification learning tasks—that used procedures expressly designed to minimize the use of explicit strategies, and one comparison explicit learning task, paired associates learning. We found implicit learning to be intact in ASC. Beyond no evidence of differences, there was evidence of statistical equivalence between the groups on all the implicit learning tasks. This was not a consequence of compensation by explicit learning ability or IQ. Furthermore, there was no evidence to relate implicit learning to ASC symptomatology. We conclude that implicit mechanisms are preserved in ASC and propose that it is disruption by other atypical processes that impact negatively on the development of skills associated with an implicit acquisition.     

Inhibitory control and emotion regulation in preschool children

This research investigated the relation between individual differences in inhibitory control and emotion regulation. Preschool children (N = 53) ages 4–6 (M = 5; 0) were assessed on brief batteries of inhibitory control of prepotent responses and emotion regulation. Individual differences in inhibitory control were significantly correlated with children's ability to regulate their emotions. This relation held up even after controlling for age and verbal ability, and persisted for both Emotion Understanding and “online” control of emotional expressions that were negative (Disappointing Gift) or positive (Secret Keeping). Parent report of children's self-control and emotion regulation corroborated the behavioral results. These findings suggest that executive control of attention, action, and emotion are skills that develop in concert in the preschool period. However, there was also evidence of a quadratic relation in which emotion regulation was optimal at intermediate levels of inhibition, highlighting the interplay of both cognitive control and temperament in socio-emotional functioning.     

Is flanker-based inhibition related to age? Identifying specific influences of individual differences on neurocognitive variables

Researchers frequently attempt to identify the specific neurocognitive processes that might be responsible for differences in performance associated with neurological status or other individual difference characteristics by administering two or more conditions of an experimental task to different groups of participants, and focusing on the group-by-condition interaction as the primary outcome of interest. Three limitations of this approach are discussed, and an alternative analytical method is proposed to overcome the limitations. The method is demonstrated in analyses of data from 10 cognitive tasks in two independent studies, including two flanker tasks which are often used to assess aspects of inhibition.     

Can discrepancies between impulsive and reflective processes be associated with movement behavior among the elderly? The facilitating role of inhibitory control

Physical activity participation remains a global public health challenge, with 8 out of 10 older adults failing to meet the minimum physical activity recommendations, and it is also associated with an increased risk of cardiovascular disease, cognitive impairment, and mortality. Strategies to promote physical activity are primarily focused on socio-cognitive factors, and their effectiveness is limited. According to dual-process theories, physical activity is related with impulsive/implicit (i.e., emotions) and reflective/explicit (i.e., perceived advantage) processes; however, implicit-explicit discrepancy (IED) may impair movement behavior. In addition, cognitive inhibitory control may have r direct relationship with IED situations since it determines which of these processes predominates in the regulation of individual's behavior. Nonetheless, these outcomes in physical activity behavior among older adults have received little attention. In this study, we associate IED with physical activity and sedentary behavior as measured by accelerometers, and investigate the moderator role of inhibitory control in this association. In this cross-sectional study, 94 older adults were assessed for implicit and explicit attitudes, inhibitory control, and movement behavior using accelerometers over the course of seven days. A higher magnitude of the IED was linked to less moderate-to-vigorous physical activity (MVPA) and daily steps. Interestingly, a higher light physical activity was associated with a direction of the IED with more positive explicit attitudes. Furthermore, in older adults with higher inhibitory control, a direction of the IED with more positive explicit attitudes than implicit attitudes was associated with higher MVPA. Our findings suggest that IED may be important factor in the physical activity behavior of older adults. Furthermore, a higher inhibitory control appears to override an impulsive negative response, enabling a more positive reflective assessment of physical activity to serve as the main driver of an active lifestyle.     

Liking for positive words and icons moderates the association between implicit and explicit self-esteem

Whereas explicit self-esteem (ESE) refers to a conscious self-evaluation, implicit self-esteem (ISE) refers to non-conscious self-evaluation. Presumably, ISE and ESE are based on different mental processes — the experiential system and the rational system, respectively (Epstein, 1994) as well as different experiences (DeHart, Pelham, & Tennen, 2006). Two studies showed that participants who more strongly preferred positive icons and positive words showed a stronger association between ISE and ESE, presumably because they are highly willing to trust their intuitions. Because the major motive of the experiential system is the hedonic principle — pursuing positive affect and avoiding negative affect (Epstein, 2010), we argue that people's reactions to unambiguously positive stimuli should reflect their reliance on their intuition. In addition, we suggest that a better understanding of intuitiveness may yield important insights into the nature of ISE and ESE.     

Explicit and implicit cognition: a preliminary test of a dual-process theory of cognitive vulnerability to depression

Two studies were conducted to test a dual-process theory of cognitive vulnerability to depression. According to this theory, implicit and explicit cognitive processes have differential effects on depressive reactions to stressful life events. Implicit processes are hypothesized to be critical in determining an individual's immediate affective reaction to stress whereas explicit cognitions are thought to be more involved in long-term depressive reactions. Consistent with hypotheses, the results of study 1 (cross-sectional; N=237) showed that implicit, but not explicit, cognitions predicted immediate affective reactions to a lab stressor. Study 2 (longitudinal; N=251) also supported the dual-process model of cognitive vulnerability to depression. Results showed that both the implicit and explicit measures interacted with life stress to predict prospective changes in depressive symptoms, respectively. However, when both implicit and explicit predictors were entered into a regression equation simultaneously, only the explicit measure interacted with stress to remain a unique predictor of depressive symptoms over the five-week prospective interval.

Gender moderates the relation between implicit and explicit self-esteem

Relative to men, women are more strongly socialized to trust their feelings and intuitions. We thus expected that the association between implicit and explicit self-esteem would be stronger for women than for men. That is, if implicit self-esteem contains a large intuitive, experiential or affective component, then people who are in touch with their feelings and intuitions should be more likely to report explicit self-esteem scores that are congruent with their implicit self-esteem scores. Six studies supported this idea by showing that the association between implicit and explicit self-esteem is indeed stronger for women than for men. This finding held in three different cultures and for two different measures of implicit self-esteem. We discuss the implications of this finding for debates regarding the nature and validity of implicit self-esteem.
