Autistic Traits and Cognitive Biases for Emotional Faces in Neurotypicals
… We examined whether cognitive biases for emotional faces were related to scores from the Autism-Spectrum Quotient (AQ), and whether our measures of cognitive biases from a dot- probe paradigm with concurrent eye tracking were comparable. We did not find sufficient evidence to relate ASD …

The tell-tale body: investigating the intertwined relationship between social cognition and visual perception through physiological indices.
… and the link between physiological reactivity to emotional cues and social abilities. Using a breaking continuous flash suppression (b-CFS) paradigm, we manipulated visual awareness of emotional stimuli and measured breakthrough times to distinguish between conscious and subconscious processing. …

Experimental studies of the impact of emotional information on analogical reasoning
… disorders. My prior research revealed that emotional information affects analogical reasoning based on its relevance: task-relevant emotional content enhances reasoning, whereas task-irrelevant content impairs it. Furthermore, the Learning and Inferences with Schemas and Analogies (LISA) …

Neuropsychological effects of anxiety without depression on facial affect perception
… and Friesen's (1976) happy, angry, and neutral emotional faces. Results were counter to hypotheses, where anxious subjects' reaction times to affective valences were slower than nonanxious subjects. Additionally, anxious subjects failed to demonstrate a negative affective bias for neutral …

Teste de atribuição das emoções em situações de bullying - AESB: evidências psicométricas
… of 38 items, which was asked to choose from five emotional faces to the characters bullying (bully, victim and bystander) of the situations. We held the principal components analysis (PCA) (Varimax rotation), the Scree test. It was set extracting 3 factors, which explain 30% of the total variance, …

Cerebral asymmetry in facial affect perception of women: neuropsychological effects of depression
… and Friesen’s (1976) happy, sad, and neutral emotional faces. A dynamometer was also used as a standardized measure of hemispheric motor functioning such as hand grip strength, perseveration, and fatigue. Results indicated that the depressed women were characterized by elevated levels of both …

Preconception Stress, Affect-Biased Attention, and Negative Affectivity: Assessing Pathways and Early Markers of Psychopathological Risk in Infancy and Childhood
… (e.g., biases in the holding of attention on emotional faces) similarly were more likely to be high in negative affectivity. These findings have important implications for understanding the preconception and perinatal determinants of mental health. Implications of these findings, limitations, …

An investigation into the emotion-cognition interaction and sub-clinical anxiety
… resources. It was previously reported that emotional expression effects on ERP waveforms were completely eliminated when attention was directed away from emotional faces to other task-relevant locations (Eimer et al., 2003). However, Bishop et al. (2004) reported that threat-related stimuli …

Resting-state Functional Connectivity Correlates of Inhibitory Control over Emotional Stimuli
… research discussing the neural mechanisms of an emotional anti-saccade task, therefore with the use of resting-state functional magnetic resonance imaging (fMRI) and an emotional anti-saccade task, this study aims to identify the neural correlates of inhibitory control over emotional stimuli. The …

The Influence of Media Violence on the Neural Correlates of Empathic Emotional Response
… prosocial behavior. Researchers suggest that emotional face processing and inhibitory control may be important factors associated with aggressive behavior and empathy; however, few researchers have examined these variables in chronic and nonchronic violent video game players. Therefore, the …

Differential effects of facial configuration on bilateral skin conductance as a function of hostility
… would show higher conductance levels across the emotional faces as compared to the neutral facial configuration than the low hostile group; (5) the high hostile group would show higher conductance levels across both extremities than the low hostile group; and (6) a three-way interaction of group, …

White Matter Microstructure and Emotional Functioning in Children Treated for Posterior Fossa Tumours
… fossa (PF) experience lifelong cognitive and emotional difficulties, and exhibit white matter (WM) damage. This thesis combined diffusion tensor imaging (DTI), eye-tracking and standardized measures of cognitive and emotional functioning in children treated for PF tumours and typically …

The Effects of Age and Task on Visual Emotion Processing
… stimuli are enhanced by positive and negative emotional expressions, with negativity leading to a greater benefit than positivity. Conversely, older adults demonstrate a positivity bias, devoting more attention to positive stimuli and less to negative. It is unclear if age differences in these …

Dissecting emotion : towards a functional neuroimaging probe for affective disorders
… mediates ?bottom-up? processing driven by emotional stimulus content, and that the ventral prefrontal cortex and anterior cingulate cortex mediate ?top-down? processing driven by explicit knowledge or intention. In the first experiment, we tested whether matching faces by emotional …

The Role of Sleep and Hormones in Processing of Emotional Information
… event-related potentials were recorded during emotional face categorization and image categorization tasks respectively. Sleep-restricted participants were less accurate identifying sad facial expressions, and displayed a larger N170 amplitude to sad faces compared to other emotional faces. On …

Can Meaning Associated with Perceptual Grouping Modulate Attention?
… and socially-important stimuli like affective faces are proposed to influence allocation of attention (Vuilleumier & Schwartz, 2001). Task-irrelevant emotional faces are proposed to capture attention in a way that is detrimental to performance on a primary task (Eastwood, Smilek & Merikle, …

The electrophysiological correlates of processing expression intensities along emotion trajectories
… Emotion trajectories were formed by morphing the emotional faces to display expressions that were 20%, 40%, 60%, 80%, or 100% of the full expression. In both Experiments 1 and 2, we recorded Electroencephalography (EEG) while participants viewed faces that were either neutral in expression, or …

Emotion Recognition, Emotion Regulation, and Callous: Unemotional Traits in Incarcerated Male Youth
Youth with Callous-Unemotional (CU) traits represent an important subgroup of antisocial youth whose behavioral, affective, and cognitive functioning appear sharply different from other youth with conduct problems. However, few, if any studies have examined the interaction of cognitive control and …

The Role of Cardiac Vagal Tone in Prediction of Individual Differences in Attention and Emotion Processing After Sleep Restriction
… have begun to study physiological responses to emotional stimuli following sleep loss. There is also interest in identification of individual difference markers of vulnerability to sleep loss. The current thesis examined the effect of sleep restriction on emotional processing: subjective mood, …
