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 role of recursive remindings on memory updating of emotional stimuli
It has been argued that emotional memories are harder to update than neutral memories (Novak & Mather, 2009; Sakaki, Niki, & Mather, 2012) and that the cause is that emotional memories are subject to greater levels of proactive interference. This explanation was questioned in this paper and another …

Does Working Memory Capacity Influence Individuals Ability to Ignore Distraction Caused by Emotional Stimuli?
Tilgangur rannsóknarinnar var að skoða hvort að einstaklingar með háa eða lága vinnsluminnispönn, sýni mismunandi frammistöðu á tilfinningatengdu stroop prófi. Tilgáturnar voru a) að þátttakendur með háa og lága vinnsluminnispönn myndu sýna svipaða frammistöðu á stroop prófi með hlutlausum orðum …

Visual attention to emotional stimuli in individuals high on psychopathic traits: Evidence from eye tracking
<p>Researchers have described psychopaths as callous, cold-hearted individuals who show reduced empathic response to their victims. It is suggested that the inability to identify negative emotions, specifically fear, in individuals is what allows psychopaths to offend/take advantage of other people …

Non-Target Emotional Stimuli Must Be Highly Conspicuous in Order to Break through the Attentional Blink
… the AB is modulated when either target has emotional valence, and an AB-like effect can be triggered when a task-irrelevant but valenced critical distractor item (CDI) replaces T1. Neither target nor CDI valence manipulations fully captures the interplay between bottom-up and top-down …

Determining the effects of emotion on prospective memory performance
… the study of prospective memory, the use of emotional stimuli tends to lead to contradictory effects. Some studies suggest that emotional stimuli, particularly positive stimuli, lead to better prospective memory performance. However, emotional stimuli have also been associated with …

Selective attention under different pressure sources and perceptual loads
… pressure effects on selective attention of non-emotional stimuli using letters, and the fourth experiment investigated emotional stimuli using emoticons. In Experiment 1, using a ""fixational"" flanker task and perceptual load manipulation, we found that under pressure, flanker effect was …

Are Emotional Video-Clips More Likely to Elicit False Memories Than Neutral Video-Clips?
… on memory have shown that individuals remember emotional stimuli better than neutral stimuli. However, studies on false memories have also shown that emotional stimuli are more likely to elicit false memories compared to neutral stimuli. In this present study, participants were asked to …

The time course of attentional bias in anxiety
Attentional bias to emotional stimuli (especially unpleasantly valenced or threatening) is a common finding in anxiety and less commonly found in depression. So-called neutral or “nonemotional” stimuli varying in attentional processing demands have not been systematically investigated or contrasted …

Memory for Emotional Images : Recognition and Temporal Contexts
<p>Negative emotional stimuli are usually better remembered than neutral emotional stimuli. Previous examination of binding theory found no differences in recall for homogeneous lists of taboo and neutral words. The current study expands on binding theory using negative and neutral visual stimuli …

Understanding the Role of the Ventrolateral Prefrontal Cortex in Emotional Memory using Transcranial Direct Current Stimulation and Transcranial Magnetic Stimulation
<p>Emotional stimuli can have both beneficial and detrimental effects on memory, such that emotional stimuli can be distracting from current neutral working memory goals, while also leading to enhanced episodic memory for the distracting emotional stimuli. Recent evidence suggests that the …

Memory for Emotional Images: Mechanisms of Episodic Processing and its Psychophysiological Correlates
Negative emotional stimuli are usually better remembered than neutral emotional stimuli. Previous examination of binding theory found no differences in recall for pure lists of taboo and neutral words. A similar result was found with equivalent recognition memory performance between pure lists of …

Modulation of lateralised responses to primary affect
… locus, or does our readiness to react to emotional stimuli depend on the differential contribution of each hemisphere based on the approach or avoidance behaviours positive and negative affect elicit? This thesis is concerned with these questions that have so far remained unanswered even …

Sympathetic Arousal During Approach-Avoidance Decision- Making
In response to emotional stimuli, individuals exhibit increased sympathetic nervous firings, which stimulate eccrine gland activation. This eccrine activity changes the electrical properties of the skin, or electrodermal activity (EDA). EDA has been used widely to assess autonomic arousal during …

Attentional Bias Modification: An Examination of Novel Training Contingencies and Stimulus Pairs
Selective attention to dysphoric stimuli is hypothesized to contribute to the onset and maintenance of emotional disorders. Over the past two decades, research on training and modifying attention as a form of treatment for anxiety and depression, Attentional Bias Modification (ABM) treatment, has …

The impact of interoceptive abilities on emotional intensity and susceptibility to distraction
… differences in interoceptive ability influences emotional experience and cognitive processes such as memory, particularly when stimuli are emotional in nature. The present study aimed to extend these propositions by examining interoceptive abilities in relation to emotional intensity (defined as …

The Effects of Anxiety and Reward Sensitivity on the Interplay Between Emotion and Reward Processing
… completed three associative matching tasks: emotional valence, value-based reward, and a control task. Participants' accuracy and response times (RTs) were measured alongside self-reported questionnaires assessing state-trait anxiety and sensitivity to reward. The results demonstrated …

Event-related potential correlates of face-emotion processing impairments in bipolar disorder
… healthy volunteers, through implementation of an emotional go/no-go task employing happy and sad face stimuli. The first analysis revealed increased parieto-occipital P100 amplitudes elicited by happy compared with sad faces in the BD group only, and overall attenuated N170 amplitudes. The second …

Immediate and long-term effects of emotion regulation: an eye-tracking investigation of focused attention on emotional experience and memory
Emotional stimuli tend to capture attention and this may lead to an immediate increase in our subjective emotional experience, as well as to longer-term enhancing effects on our memory for emotional stimuli. In extreme circumstances, increased emotional reactivity to negative stimuli may become …
