Effortful control is associated with executive attention: A computational study.

INTRODUCTION: Effortful control (EC) is the self-regulatory aspect of temperament that is thought to reflect the efficiency of executive attention (EA). Findings on relationship between EC and performance on EA tasks among adults are still contradictory. This study used a computational approach to clarify whether greater self-reported EC reflects better EA. METHODS: Four hundred twenty-seven healthy subjects completed the Adult Temperament Questionnaires and the Attention Network Task-revised, a conflict resolution task that gauges EA as the flanker effect (FE), that is, the difference in performances between incongruent and congruent trials. Here we also employed a drift-diffusion model in which parameters reflecting the actual decisional process (drift rate) and the extra-decisional time are extracted for congruent and incongruent trials. RESULTS: EC was not correlated with the FE computed with the classic approach, but correlated positively with drift rate for the incongruent trials, even when controlling for the drift rate in the congruent condition and the extra-decisional time in the incongruent condition. CONCLUSION: This study demonstrates an association between self-reported EC and EA among adults. Specifically, EC is not associated with overall response facilitation but specifically with a greater ability to make goal-oriented decisions when facing conflicting information.

Facial Emotion Recognition and Social-Cognitive Correlates of Narcissistic Features.

Narcissistic personality disorder (NPD) is associated with both seeming indifference and hypersensitivity to social feedback. This study evaluated whether rejection sensitivity and empathic difficulties in NPD are accounted for by altered facial emotion recognition (FER). Two-hundred non-clinical individuals self-reported NPD features, rejection sensitivity, and empathy and performed an FER task assessing the ability to determine the presence or absence of an emotion when viewing neutral and negative facial stimuli presented at varying emotional intensities (25%, 50%, 75%). Those with higher NPD features were faster at accurately recognizing neutral and low, 25%-intensity emotional stimuli. This response pattern mediated the association between NPD features and increased anger about rejection. Thus, individuals with high NPD traits are hypervigilant toward subtle negative emotions and neutral expressions; this may explain their tendency to experience intense angry feelings when facing the possibility that the others would not meet their need for acceptance.

Facial emotion recognition and borderline personality pathology.

The impact of borderline personality pathology on facial emotion recognition has been in dispute; with impaired, comparable, and enhanced accuracy found in high borderline personality groups. Discrepancies are likely driven by variations in facial emotion recognition tasks across studies (stimuli type/intensity) and heterogeneity in borderline personality pathology. This study evaluates facial emotion recognition for neutral and negative emotions (fear/sadness/disgust/anger) presented at varying intensities. Effortful control was evaluated as a moderator of facial emotion recognition in borderline personality. Non-clinical multicultural undergraduates (n = 132) completed a morphed facial emotion recognition task of neutral and negative emotional expressions across different intensities (100% Neutral; 25%/50%/75% Emotion) and self-reported borderline personality features and effortful control. Greater borderline personality features related to decreased accuracy in detecting neutral faces, but increased accuracy in detecting negative emotion faces, particularly at low-intensity thresholds. This pattern was moderated by effortful control; for individuals with low but not high effortful control, greater borderline personality features related to misattributions of emotion to neutral expressions, and enhanced detection of low-intensity emotional expressions. Individuals with high borderline personality features may therefore exhibit a bias toward detecting negative emotions that are not or barely present; however, good self-regulatory skills may protect against this potential social-cognitive vulnerability.

Alexithymia and self-reflectiveness in bronchial asthma.

The aim of the study was to investigate the role of alexithymia in bronchial asthma (BA) patients with low respiratory functioning hypothesizing that it could be used to differentiate a group of patients with clinically significant anxiety and depressive symptoms. We also aimed to investigate whether alexithymia was associated with reduced cognitive insight. Patients (n=153) were administered the State- Trait Anxiety Inventory-State subscale, the Beck Depression Inventory, the Toronto Alexithymia Scale, and the Beck Cognitive Insight Scale (BCIS). Alexithymia could help differentiate a group of patients with low respiratory functioning. Twenty-two percent of patients included in this subsample had airway obstruction, and 51% reported severe alexithymia. Patients with severe airway obstruction and high alexithymia (compared to other patients) also reported higher self-reflectiveness, and more depressive symptoms. Clinicians have to be aware of the presence of a subgroup of asthma patients with low respiratory functioning who report severe alexithymia. These patients often report moderate to severe depression and frequent doubts about one's own beliefs.

Parsing the intrinsic networks underlying attention: a resting state study.

The attention system functionally modulates brain activity to exert control over thoughts, feelings and actions. Three distinct but mutually interacting components of attention have been hypothesized: alerting, which mediates the maintenance of a state of vigilance toward an upcoming stimulus; orienting, which supports the selection of sensory information, and executive control that is involved in detecting and resolving cognitive conflicts. The performance of tasks probing these components engages fronto-parietal and thalamic regions. Also, general attention has been associated with the activity of resting-state networks (RSNs), which are sets of brain regions with synchronous temporal fluctuations. Importantly, the association between the intrinsic brain activity of RSNs and the efficiency and integration of the specific attentional components remains largely unexplored. For this aim, we recruited twenty healthy volunteers who performed the Attention Network Test-Revised (ANT-R), assessing the alerting, orienting and executive control components as well as their interactions, and underwent resting-state functional magnetic resonance imaging. For each participant RSNs were estimated using double regression. The RSNs spanning across areas previously implicated in attentional processing were correlated with ANT-R scores using multiple regressions. Significant brain behavior correlations emerged between ANT-R scores and RSNs comprising the regions relevant for attentional processing, i.e., left and right prefronto-parietal (PFC-PC), dorsal attentional (DAN), salience (SN), and default mode (DMN) networks. The activity of PFC-PC networks was correlated with alerting in parietal and frontal regions, and with location conflict in the frontal regions. The DAN connectivity was correlated with flanker, location conflict, and their interaction in parietal regions. SN was associated with flanker by location and flanker by orienting interactions in the inferior frontal regions. Finally, the activity of the DMN was associated with flanker conflict in midline structures such as precuneus and anterior cingulate cortex and also in right angular gyrus. These results suggest that the brain is endowed with an intrinsic functional organization to support attention, not only in its global function, but also in its distinct components.

Disease control in patients with asthma is associated with alexithymia but not with depression or anxiety.

This observational cohort study investigated the relationship between alexithymia, coping strategies, anxiety, depression, pulmonary function, and disease control in bronchial asthma (BA) patients who attended a tertiary care center between December 2010 and November 2011. Participants (N = 117) were administered self-report scales measuring anxiety, depression, alexithymia, and coping strategies. Pulmonary function expressed as forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), forced expiratory flow rate over the middle 50% of the FVC (FEF25-75) as% predicted and FEV1/FVC as%, fractional exhaled nitric oxide (FeNO) in ppb and the Asthma Control Test (ACT) were recorded. A hierarchical cluster analysis revealed two clusters of patients with different FEV1 values (p < .001) and alexithymia scores (p < .001). The cluster with lower FEV1 and higher alexithymia used more maladaptive coping strategies (p < .05), and had lower ACT scores (p < .05). Alexithymia was significantly associated with the severity of depression and anxiety symptoms (p < .001 for each comparison). In BA patients, alexithymia was associated with worse pulmonary function and disease control and a more frequent use of maladaptive coping strategies. These results support a multidimensional approach to asthmatic patients, including psychoeducational and behavioral interventions aimed at reducing maladaptive coping strategies.
