EVALUATING THE USE OF SELF-RELEVANT STIMULI IN ATTENTION BIAS MODIFICATION TRAINING AS A TREATMENT FOR ANXIETY: A NEAR-INFRARED SPECTROSCOPY STUDY
… group completed a self-relevant variant of the dot-probe task in place of ABM. Pre and post-testing, consisting of the dot-probe task while NIRS activity was recorded, did not reveal significant changes in behavior or brain activation. However, examination of the control group’s data revealed …

PREFRONTAL CORTEX ACTIVITY DURING ATTENTIONAL BIAS CONDITIONING WITH FEARFUL FACES: A NEAR-INFRARED SPECTROSCOPY ANALYSIS
… a colored square with a fearful face in the dot-probe task. Orienting toward and disengagement from fearful faces was also examined using the dot-probe task. In addition, hemodynamic responses in the prefrontal cortex (PFC) were measured using near-infrared spectroscopy (NIRS). It was …

An Assessment of Frontal Lobe Activity and BDNF Levels Following Concussion in Collegiate Athletes: A Near-Infrared Spectroscopy Study
… prefrontal cortex (PFC) activity during the dot-probe task of affective attentional bias. Brain-derived neurotrophic factor (BDNF) levels are related to frontal lobe activity, recovery from brain injury, attention, and affective processing. Therefore, BDNF levels were collected to assess …

The Association between Callous-Unemotional Traits and Emotional Processing Within Individuals and Across Generations
… with one parent, using the emotional pictures dot-probe task, which is a computerized task measuring attention to emotional pictures in the form of a facilitation score. The relationship between emotional processing, CU traits, and TAS were examined to determine whether individuals high on CU …

The causal role of selective information processing biases towards threat in anxiety
… training. Training was given on a modified dot-probe detection task, where participants were trained either to attend towards threat or towards neutral stimuli. Pre and post training assessment consisted of the anagram stress task (measure of emotional vulnerability), the dot-probe detection …

The Role of Attention in Ego-Depletion
… the effect of ego depletion on attention via a dot probe task, while Study 2 assessed the effect of attentional bias on self-regulatory ability during an eating task. No ego-depletion effect was observed to affect attention toward reward cues or away from self-control cues in the first study, …

Why Be Mindful?: A Profile Approach to Understanding the Role of Motivation in Emotion Regulation
… state-level self-reports, as well as a computer task of selective attention, at several time points during a stressful encounter. A typological approach to analysis was used, in which individuals were assigned to a Mindful, Avoidant, or Vigilant motivation to observe and z-scores of the three …

Effect of Depression on Attention via Mood Induction in a Healthy Population
… by dysthymia. The project utilizes the Dot Probe Task to evaluate attention to affective stimuli presented in the International Affective Picture Set (IAPS). Participants were psychology students recruited from La Sierra University. Participants completed a word task that intended to …

ELECTROCORTICAL CHANGES OBSERVED IN THE N2 AS AN OUTCOME OF ATTENTION BIAS MODIFICATION TRAINING
… Each participant completed an attention bias task, questionnaires for anxiety and emotion related traits, as well as an EEG session (i.e., flanker task) pre and post the 6-week ABM training period. ABM training was administered through a modified dot-probe task; training attention away from …

Attentional Bias to Threat Following Acquired Brain Injury: The Role of Self-Discrepancy and Executive Functioning
… who had sustained an ABI completed a visual dot-probe task, alongside measures of self-discrepancy, affective distress and executive functioning. Results: Whilst the pattern of results is indicative of this threat detection hypothesis, the difference between threat and neutral trials was …

The Role of Test Anxiety in Attention Bias to Test Threats in Undergraduates: The Influences of Temperamental Effortful Control and Frontal EEG Asymmetry
… and test anxiety in undergraduate students. A dot-probe task with test threat words as the target was given to the students. Paired-sample T tests show the presence of an AB to test threats in the endogenous (i.e., 500ms) condition but not in the exogenous (i.e., 250ms) condition. Hierarchical …

Personality resources and stress reactivity : potential mechanisms in stress-related psychopathology
… students who were assigned the stress-inducing task of preparing and presenting a speech for evaluation by a panel of "judges". Stress was assessed via a mood questionnaire and heart rate. Selective attention was evaluated using a reaction time computer task in which participants responded to a …

Attentional bias towards positive and negative imagery amongst offenders and non-offenders with intellectual disabilities
… a self-report empathy measure, and an affective dot-probe task containing negative, positive, and neutral images. Reaction times (RT) to computerised trials were recorded. Results: (1) The IDO group had significantly lower empathy scores than the IDNO group; (2) within group comparisons showed …

Investigating Steady State Visually Evoked Potentials as a Novel Biosignature for Anxiety-Related Attention Bias
… generated while 95 adults completed a modified dot probe task in which angry and neutral face pairs flickered at unique frequencies. Contrary to our hypotheses, results showed that SSVEP to threat was not heightened among those with severe anxiety relative to those with mild or moderate anxiety; …

Food attentional biases and adiposity: are energy intake and external eating mediators of this relationship?
… reaction time bias obtained from a visual dot-probe task and direction bias and duration bias obtained from eye tracking. Adiposity indices of body mass index (kg/m2) and body fat percent were measured using standard medical devices. Data were obtained for two mediators: 1) energy intake …
