Attention toward interpersonal stimuli in individuals with and without chronic daily headache
No full textAttentional capture of threat is a normal and adaptive process, although facilitated processing of mildly threatening stimuli irrelevant to current goals may result in attentional interference and compromised performance. In the field of chronic pain, attentional biases towards pain-related information have been commonly found. Pain is inexorably connected with emotion however, and a transdiagnostic approach elucidating similar mechanisms underlying pain and mood disorders has been advocated. One such mechanism may be repetitive thinking on negative themes, including worry and rumination. Attentional biases for threatening (e.g., angry faces) and negative (e.g., sad faces) information have been observed in anxious and depressed populations, although to date it has not been fully established whether biases for such information are heightened in individuals with chronic pain relative to healthy individuals. In this study, attentional biases for angry, sad and also happy facial expressions, at 500 and 1250 ms presentation times, were assessed via visual-probe task in chronic daily headache (n = 20) and healthy control (n = 26) groups. Results showed participants to demonstrate significant bias towards angry and sad expressions at 500 and 1250 ms, and happy expressions at 1250 ms. No significant differences in attentional bias were found between chronic daily headache and healthy control groups. These results suggest that attentional biases towards interpersonal threat are not specifically heightened in individuals with chronic daily headache. While similar mechanisms such as rumination may underlie biases in different disorders, this does not translate to heightened biases for the same specific content
Attentional bias toward pictorial representations of pain in individuals with chronic headache
No full textObjectives: This study investigated attentional biases for pictorial headache-related stimuli in individuals with chronic headache and healthy controls.Methods: Attentional bias was assessed using a visual probe task that presented headache-related images and neutral images at 2 exposure duration conditions, 500 and 1250?ms.Results: The results indicated that individuals with chronic daily headache showed a significantly greater overall attentional bias across presentation times toward headache-related stimuli compared with the controls, which indicates a bias in both initial orienting and maintained attention to pain cues in this group.Discussion: It is concluded that both hypervigilance and sustained processing are critical factors for the maintenance of chronic pain

Dataset to support the thesis 'The interactions between pain-related cognitive biases for somatosensory and visual information'
No full textThis dataset supports the Southampton Doctoral thesis entitled "The interactions between pain-related cognitive biases for somatosensory and visual information".
Experiment_2_data is the dataset underpinning an experiment which aimed to investigate the association between interpretation bias (IB) for ambiguously pain-related visual information and IB for ambiguously painful somatosensory stimuli.
More specifically, the experiment investigated the effect of interpretation bias modification (IBM) with the Ambiguous Situations Task (Jones & Sharpe, 2014) on interpretation of ambiguous somatosensory stimuli, as well as the effects of IBM on directly and indirectly measured interpretation of ambiguous, pain-related language. A novel task, the Interpretation of Ambiguous Sensations Task, was developed to assess interpretation of ambiguous somatosensory stimuli. Interpretation of ambiguous pain-related language was assessed directly with the sentence generation task and indirectly with the incidental learning task.
Experiment_3_data is the dataset underpinning an experiment which aimed to investigate whether interpretation bias modification (IBM) can modify interpretation of painful sensations for individuals with chronic pain. Based on the Process Model of Emotion Regulation, it was hypothesised that IBM may teach participants a cognitive change emotion regulation strategy which is then used in pain-related situations to inhibit negative emotions.
This study investigated whether IBM reduced negative emotional response to pain and to pain-related images, and whether this effect was mediated by reduction in pain-related interpretation bias (IB) and fear of pain. The sample for this experiment was comprised of 41 participants with chronic musculoskeletal pain and 41 healthy participants. The study took place online and participants were supported by a researcher over video call. </span
