Xu T, Vancleef LMG, Peters ML, Van Ryckeghem DML. The Interrelationships Between Cognitive Biases for Pain: An Experimental Study. THE JOURNAL OF PAIN 2024:104587. [PMID: 38834148 DOI: 10.1016/j.jpain.2024.104587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/11/2024] [Accepted: 05/28/2024] [Indexed: 06/06/2024]
Abstract
Contemporary pain models highlight cognitive-processing biases (ie, attention bias [AB], interpretation bias [IB], and memory bias [MB]) as key processes that contribute to poor pain outcomes. However, existing research has yielded inconsistent findings regarding the presence and impact of these biases on pain outcomes. Recognizing the need to explore these biases simultaneously, contemporary pain models suggest that cognitive biases (CBs) are interrelated, and may have a combined impact upon pain problems. The current study aims to investigate the interrelationships between CBs using the PainAIM paradigm, a novel approach enabling simultaneous evaluation of pain-related AB, IB, and MB using cues signaling actual pain rather than symbolic information. We hypothesized the presence and positive associations of biases for pain-related cues and the predictive value of combined AB and IB for poor pain outcomes. Eighty-four healthy participants completed the PainAIM paradigm, followed by a cold pressor task probing pain experience and pain-related task interference. The results indicated an inverse relationship between AB and IB for ambiguous pain cues. In addition, there was a positive association between participants' AB for ambiguous pain and their MB for the same cues. Contrary to our hypotheses, CB indices did not predict experimental pain outcomes. These findings provide support for the interrelationships between pain-related CBs. However, future research on the temporal order of CBs and their combined impact on pain outcomes is needed. By overcoming the limitations associated with traditional paradigms, the PainAIM paradigm offers a promising research tool for the further study of combined CBs in the context of pain. PERSPECTIVE: The current study provides insight into the associations between pain-related CBs (AB, IB, and MB) using ecologically valid (ambiguous) pain cues. The results indicated an inverse association between pain-related AB and IB, while a positive association was found between AB and MB. CBs did however not predict experimental pain outcomes.

Abstract
Introduction Anger is a basic emotion helping people to achieve goals by preparing the body for action and prompting others to change their behavior but is also associated with health issues and risks. Trait anger, the disposition to experience angry feelings, goes along with an attribution of hostile traits to others. Negative distortions in the interpretation of social information have also been observed in anxiety and depression. The present study examined the associations between components of anger and negative interpretation tendencies in the perception of ambiguous and neutral schematic faces controlling for anxiety, depressed mood, and other variables. Methods A sample of 150 young adults performed a computer-based perception of facial expressions task and completed the State-Trait Anger Expression Inventory (STAXI-2) along with other self-report measures and tests. Results Trait anger and anger expression correlated with the perception of negative affects in neutral but not in ambiguous faces. More specifically, trait anger was linked to the attribution of anger, sadness, and anxiety to neutral faces. Trait anger predicted perceived negative affects in neutral faces when adjusting for anxiety, depression, and state anger. Discussion For neutral schematic faces, the present data support an association between trait anger and negatively biased interpretation of facial expression, which is independent of anxiety and depressed mood. The negative interpretation of neutral schematic faces in trait angry individuals seems not only to comprise the attribution of anger but also of negative emotions signaling weakness. Neutral schematic facial expressions might be useful stimuli in the future study of anger-related interpretation biases.

Abstract
Chronic pain and insomnia are highly comorbid: Approximately 50% of those with chronic pain experience insomnia or clinically significant sleep disturbances, and 50% of those with insomnia experience chronic pain. Further, these conditions can be extremely disabling, particularly when they co-occur. There is increasing recognition of the need to tackle both chronic pain and insomnia together, as evidenced by growing empirical research in this area. Cognitive processing biases have been independently implicated in both chronic pain and in insomnia. Given their trans-diagnostic status, cognitive biases may therefore have a role in explaining the co-occurrence and mutual maintenance of these conditions. These biases also represent novel, potentially modifiable targets for treatment. However, the role of cognitive biases has not been adequately explored in comorbid chronic pain and insomnia. Here, we describe the state of cognitive bias research in chronic pain and insomnia, considering evidence for the roles of attentional bias, interpretation bias, expectancy bias, and memory bias. In reviewing the literature, it is apparent that similar cognitive biases operate in insomnia and chronic pain, with preliminary, albeit sparse, evidence of pain-related cognitive biases influencing sleep-related outcomes. On the basis of current findings and separate theoretical models, we present a novel, testable cognitive model of comorbid chronic pain and insomnia, to guide future research in this area. Key recommendations for the future of this relatively new field are provided. PERSPECTIVE: Chronic pain and insomnia are highly co-morbid, suggesting an overlap in causal mechanisms. Empirical research, although sparse, suggests that cognitive biases may play a role in their development and mutual maintenance. Our novel cognitive model generates research avenues of clinical importance for treating co-morbid chronic pain and insomnia.

Abstract
Attention to emotions and emotional clarity are core dimensions of individual differences in emotion awareness. Findings from prior research based on self-report indicate that attention to and recognition of one's own emotions are related to attention to and recognition of other people's emotions. In the present experimental study, we examined the relations of attention to and clarity of emotions with the efficiency of facial affect perception. Moreover, it was explored whether attention to and clarity of emotions are linked to negative interpretations of facial expressions. A perception of facial expressions (PFE) task based on schematic faces with neutral, ambiguous, or unambiguous emotional expressions and a gender decision task were administered to healthy individuals along with measures of emotion awareness, state and trait anxiety, depression, and verbal intelligence. Participants had to decide how much the faces express six basic affects. Evaluative ratings and decision latencies were analyzed. Attention to feelings was negatively correlated with evaluative decision latency, whereas clarity of feelings was not related to decision latency in the PFE task. Attention to feelings was positively correlated with the perception of negative affects in ambiguous faces. Attention to feelings and emotional clarity were not related to gender decision latency. According to our results, dispositional attention to feelings goes along with an enhanced efficiency of facial affect perception. Habitually paying attention to one's own emotions may facilitate processing of external emotional information. Preliminary evidence was obtained suggesting a relationship of dispositional attention to feelings with negative interpretations of facial expressions.

Abstract
Cognitive factors are thought to contribute and maintain pain experiences in young people. However, most of these factors have been assessed in isolation. Considering more than 1 cognitive factor could increase explanatory power and identify multiple targets for intervention. Here, we tested a Combined Cognitive Bias Hypothesis (CCBH) that suggests information-processing factors associate with each other and exert either additive and/or interactive influences on pain outcomes. We conducted secondary analysis of data from 243 adolescents aged 16 to 19 years, who had completed a task measuring pain-related attention control impairments (emotion-priming visual search task) and a task measuring biased interpretations towards threatening cues (Adolescent Interpretation of Bodily Threat task). These young people also completed measures of recent pain experiences and pain catastrophizing, which served as primary and secondary outcomes, respectively. Regression analyses revealed that difficulties with attention control (following presentation of pain-related stimuli) and tendencies to endorse threatening interpretations of ambiguous situations had significant additive effects on both pain outcomes. However, correlations between these factors were non-significant. They also did not interact to influence pain outcomes. These findings require replication in broader age ranges and clinical samples but potentially suggest that, measuring multiple cognitive factors increases explanatory power of youth pain outcomes. PERSPECTIVE: Weak attention control following exposure to pain cues and tendencies to endorse threat interpretations, uniquely and additively associate with self-reported pain experiences and pain catastrophizing in community youth. Measuring several cognitive factors simultaneously could improve our ability to explain pain outcomes in adolescent populations.

Abstract
ABSTRACT Attentional bias to pain-related information may contribute to chronic pain maintenance. It is theoretically predicted that attentional bias to pain-related language derives from attentional bias to painful sensations; however, the complex interconnection between these types of attentional bias has not yet been tested. This study aimed to investigate the association between attentional bias to pain words and attentional bias to the location of pain, as well as the moderating role of pain-related interpretation bias in this association. Fifty-four healthy individuals performed a visual probe task with pain-related and neutral words, during which eye movements were tracked. In a subset of trials, participants were presented with a cold pain stimulus on one hand. Pain-related interpretation and memory biases were also assessed. Attentional bias to pain words and attentional bias to the pain location were not significantly correlated, although the association was significantly moderated by interpretation bias. A combination of pain-related interpretation bias and attentional bias to painful sensations was associated with avoidance of pain words. In addition, first fixation durations on pain words were longer when the pain word and cold pain stimulus were presented on the same side of the body, as compared to on opposite sides. This indicates that congruency between the locations of pain and pain-related information may strengthen attentional bias. Overall, these findings indicate that cognitive biases to pain-related information interact with cognitive biases to somatosensory information. The implications of these findings for attentional bias modification interventions are discussed.

Abstract
ABSTRACT Pathophysiological causes of low back pain (LBP) remain generally unclear, so focus has shifted to psychosocial features and central pain processing. Effects of attentional and affective manipulation on conditioned pain modulation (CPM) and tonic pain perception were examined in thirty recurrent LBP patients in two sessions, one with and one without clinical pain, and compared to healthy participants. Phasic cuff pressure on one leg, scored on a numerical rating scale (NRS), was used for test-stimuli (TS) and contralateral tonic cuff pain rated on an electronic visual analogue scale (eVAS) was the conditioning-stimulus (CS). TS were assessed before and during: 1) control with no manipulation/CS, 2) three attentional manipulations (Flanker with/without CS or CS-Only), and 3) three affective manipulations (positive, neutral, negative pictures) with CS. Greater inhibition of TS-NRS scores was observed in CS-only (P=0.028), combined CS&attention (P=0.026), and CS&Positive (P=0.006) than Control paradigms, and greater in CS&Positive (P=0.019) than CS&Negative paradigms. eVAS scores of CS pain increased throughout all paradigms with CS (P<0.05), except the CS&Positive paradigm, and greater facilitation was observed in the CS-Only paradigm than all others (P<0.02) and lower facilitation was additionally observed in the CS&Positive paradigm compared to CS&Attention and CS&Negative paradigms (P<0.01). Flanker effects and interruptive effects of CS pain on attention were observed consistent with prior findings, and affective manipulation produced less shift in valence among people with RLBP than controls (P<0.05). Attention and positive affect with CS pain evoked CPM, and all attentional/affective tasks, especially positive affect, reduced facilitation of CS pain.

Abstract
BACKGROUND Side effect warnings can contribute directly to their occurrence via the nocebo effect. This creates a challenge for clinicians and researchers, because warnings are necessary for informed consent, but can cause harm. Positive framing has been proposed as a method for reducing nocebo side effects whilst maintaining the principles of informed consent, but the limited available empirical data are mixed. PURPOSE To test whether positive attribute framing reduces nocebo side effects relative to negative framing, general warning, and no warning. METHODS Ninety-nine healthy volunteers were recruited under the guise of a study on virtual reality (VR) and spatial awareness. Participants were randomized to receive positively framed ("7 out of 10 people will not experience nausea"), negatively framed ("3 out of 10 people will experience nausea"), general ("a proportion of people will experience nausea"), or no side effect warnings prior to VR exposure. RESULTS Receiving a side effect warning increased VR cybersickness relative to no warning overall, confirming that warnings can induce nocebo side effects. Importantly, however, positive framing reduced cybersickness relative to both negative framing and the general warning, with no difference between the latter two. Further, there was no difference in side effects between positive framing and no warning. CONCLUSIONS These findings suggest that positive framing not only reduces nocebo side effects relative to negative framing and general warnings, but actually prevents nocebo side effects from occurring at all. As such, positive attribute framing may be a cheap and ethical way to reduce nocebo side effects.

Abstract
ABSTRACT Psychological models of chronic pain (CP) highlight cognitive-processing biases (ie, attentional biases, interpretation biases, and attentional control) as pivotal processes that uniquely and synergistically impact the development and maintenance of CP. Very few studies explore multiple cognitive biases, and no studies have examined these 3 processes together in a CP sample. Furthermore, there is a lack of research investigating the relationship between these cognitive processes and pain-relevant variables (eg, pain intensity and pain catastrophising). The current study aimed to (1) compare attentional biases, interpretation biases, and attentional control in people with and without CP, (2) explore their interrelationships, and (3) explore their association with pain-related variables. Seventy-four participants with CP and 66 without pain volunteered. Participants completed a visual scanning task with eye tracking, a recognition task, and a flanker task. Traditional and Bayesian analysis indicated no effect of pain status on cognitive-processing biases. All participants, regardless of pain status, demonstrated attentional biases towards pain on some indices of early and late attention, but not interpretation bias or attentional control. There was weak evidence of associations between attentional biases, interpretation biases, and attentional control. Pain intensity was significantly correlated with interpretation biases, and follow-up analyses revealed people with high pain intensity demonstrated an interpretation bias towards pain significantly more than those with low pain intensity. Findings suggest that attentional biases towards pain are ubiquitous, but for people with moderate-to-severe pain, interpretation biases may have a role worthy of further research.

Abstract
ABSTRACT Previous meta-analyses investigating attentional biases towards pain have used reaction time measures. Eye-tracking methods have been adopted to more directly and reliably assess biases, but this literature has not been synthesized in relation to pain. This meta-analysis aimed to investigate the nature and time course of attentional biases to pain-related stimuli in participants of all ages with and without chronic pain using eye-tracking studies and determine the role of task parameters and theoretically relevant moderators. After screening, 24 studies were included with a total sample of 1425 participants. Between-group analyses revealed no significant overall group differences for people with and without chronic pain on biases to pain-related stimuli. Results indicated significant attentional biases towards pain-related words or pictures across both groups on probability of first fixation (k = 21, g = 0.43, 95% confidence interval [CI] 0.15-0.71, P = 0.002), how long participants looked at each picture in the first 500 ms (500-ms epoch dwell: k = 5, g = 0.69, 95% CI 0.034-1.35, P = 0.039), and how long participants looked at each picture overall (total dwell time: k = 25, g = 0.44, 95% CI 0.15-0.72, P = 0.003). Follow-up analyses revealed significant attentional biases on probability of first fixation, latency to first fixation and dwell time for facial stimuli, and number of fixations for sensory word stimuli. Moderator analyses revealed substantial influence of task parameters and some influence of threat status and study quality. Findings support biases in both vigilance and attentional maintenance for pain-related stimuli but suggest attentional biases towards pain are ubiquitous and not related to pain status.

No evidence that attentional bias towards pain-related words is associated with verbally induced nocebo hyperalgesia: a dot-probe study. Pain Rep 2021; 6:e921.

Abstract
Supplemental Digital Content is Available in the Text. This study examined attention as a mechanism of nocebo hyperalgesia. No association was observed between attentional bias towards pain-related words and nocebo hyperalgesia. Introduction: Placebo and nocebo effects in pain are well documented. One leading explanation is that instructions indicating that pain will either increase or decrease after receipt of a treatment give rise to expectations for increased or decreased pain. However, the psychological mechanisms through which expectations affect pain perception are not well understood. One possibility is that the expectation of increased pain leads to anticipatory anxiety, which in turn increases attention towards painful sensations. Objectives: The aim of this study was to test the hypothesis that attention mediates nocebo hyperalgesia. This was done by measuring attentional bias towards pain using a dot-probe task both before and after a nocebo manipulation. Methods: Ninety-six healthy volunteers were randomized to receive one of the following: (1) an inert nasal spray with placebo instructions, (2) an inert nasal spray with nocebo instructions, or (3) no treatment. Participants completed measures of expectations, anxiety, and attention bias (dot-probe paradigm) both before and after randomization. Results: Results showed that the nocebo instructions induced expectations for increased pain and resulted in nocebo hyperalgesia. Conversely, the placebo instruction failed to induce expectations for decreases in pain and did not demonstrate any placebo analgesia. Furthermore, despite the significant expectancies for pain and subsequent nocebo hyperalgesia, there were no differences between the nocebo group and either the placebo or no-treatment group for anxiety or attentional bias. Conclusion: The results are consistent with the expectancy model of placebo and nocebo effects. That is, changes in expectations seemed to be necessary to induce a placebo or nocebo effect. However, there was no evidence that anxiety or attention bias towards pain-related stimuli was necessary to achieve nocebo hyperalgesia.

Abstract
Background Although dot-probe paradigms have been widely used in previous studies to investigate the attentional bias of perfectionists, the exact characteristics of this bias are still unclear. Methods In this study, eye-tracking technology was used to compare the attentional patterns of high perfectionists (HP) and low perfectionists (LP). The HP and LP groups (n = 39 vs 34) completed a visual attention task in which they observed perfect vs imperfect picture pairs, during which their eye movements (EMs) were recorded automatically using an EM tracking system. Results Both the HP and LP groups showed an overall attentional bias toward imperfect pictures, as indicated by the criteria of initial visual attention orientation and attentional maintenance. There were no significant differences between the HP and LP groups during the early and middle phases of attention: both groups exhibited a longer total fixation duration on imperfect pictures than on perfect pictures. However, during the late phase of attention, the participants in the HP group diverted their attention away from the imperfect pictures and began to pay more attention to the perfect pictures. By contrast, the participants in the LP group consistently exhibited longer fixation times for imperfect pictures than the HP group during the entire duration of the stimulus. Conclusion These findings indicate that the participants in the HP group tended to avoid imperfect stimuli during the late phase of attention; this may indicate that avoidance plays an important role in maintaining perfectionism. This study also shows that eye-tracking is a useful methodology for measuring the attentional biases of perfectionists.

Abstract
BACKGROUND AND OBJECTIVES Amongst social contextual influences on pain, the manner in which pain and painful procedures are communicated to patients is considered an important contributor to the subjective experience of pain. Threatening information, e.g., by the use of technical language, is suggested to increase pain reports. Validation, or communicating understanding towards another person reporting personal experiences, is suggested to reduce pain. The current study examines effects of both information language (technical vs. plain language) and validation (validation vs. invalidation) on the subjective experience of experimentally induced pain. METHODS Pain-free participants (N = 132) were randomly assigned to one of four groups as formed by manipulations of validation and information language. After reading a description concerning the upcoming thermal stimulus formulated in technical or plain language, participants engaged in a computer controlled simulation (CCS; based on virtual reality technology). Participants received three thermal stimuli while interacting with an avatar who either validated or invalidated their experience during the CCS. Pain intensity and pain unpleasantness were assessed after each stimulus. RESULTS The validation manipulation showed to be effective, but the information language manipulation did not induce differential threat expectancies. Results show no effect of validation or information language on subjective pain reports. LIMITATIONS Suboptimality of the information language manipulation and shortcomings of the CCS procedure might account for current findings. CONCLUSIONS The study offers an interesting model for the further experimental study of isolated and combined effects of (social) contextual factors on pain. Diverse future research avenues are discussed.

Abstract
Chronic pain is a serious public health problem that has grown exponentially in recent years, which is why it has received the attention of numerous researchers. Most of the studies in the field of chronic pain have focused on care as a mediating variable on the perception of painful stimuli and emotions. Nevertheless, there are very few studies that have gone in the opposite direction. This study's aim is therefore to analyse the impact of emotional variables (anxiety and depression), the rating of pain, and age on vigilance processes in a sample of patients with chronic pain. To do so, the attentional performance of a cohort of 52 patients with chronic pain was measured through the use of a modified dot-probe task. Furthermore, all the participants were evaluated using the following self-report measures: Beck's Depression Inventory-II (BDI-II), the McGill Pain Questionnaire, and the Pain Anxiety Symptoms Scale-20 (PASS-20). Stepwise multiple linear regression analysis revealed a significant negative correlation between the pain rating index and the number of mistakes the participants made during the attention test. There was also a positive and significant correlation with age and another negative and significant correlation with cognitive anxiety regarding the overall performance times during the undertaking of the experimental task. These results point to the importance of a more in-depth understanding of the impact that the emotional variables and other variables such as age have on attentional processes and the rating of pain. Finally, the discussion focuses on the implications these results could have for clinical practice or for future research studies in this field.

Abstract
BACKGROUND Theories propose that interpretation biases and attentional biases might account for the maintenance of chronic pain symptoms, but the interactions between these two forms of biases in the context of chronic pain are understudied. METHODS To fill this gap, 63 participants (40 females) with and without chronic pain completed an interpretation bias task that measures participants' interpretation styles in ambiguous scenarios and a novel eye-tracking task where participants freely viewed neutral faces that were given ambiguous pain/health-related labels (i.e. 'doctor', 'patient' and 'healthy people'). Eye movements were analysed with the Hidden Markov Models (EMHMM) approach, a machine-learning data-driven method that clusters people's eye movements into different strategy subgroups. RESULTS Adults with chronic pain endorsed more negative interpretations for scenarios related to immediate bodily injury and long-term illness than healthy controls, but they did not differ significantly in terms of their eye movements on ambiguous faces. Across groups, people who interpreted illness-related scenarios in a more negative way also focused more on the nose region and less on the eye region when looking at patients' and healthy people's faces and, to a lesser extent, doctors' faces. This association between interpretive and attentional processing was particularly apparent in participants with chronic pain. CONCLUSIONS In summary, the present study provided evidence for the interplay between multiple forms of cognitive biases. Future studies should investigate whether this interaction might influence subsequent functioning in people with chronic pain.

Abstract
BACKGROUND The association between fear of pain (FOP) and pain intensity has remained unclear. This study aimed to examine whether highly pain-fearful participants showed pain perceptual biases to general painful stimulus or to specific threatening painful stimulus. METHODS Fifty-nine undergraduates were recruited into low (n = 30) and high (n = 29) FOP groups and completed a threatening pain perception task with two tasks. Task 1 assessed pain perceptual biases by calculating the percentage of near-threshold pain stimulus judged as painful and assessing the average pain intensity ratings to those painful stimuli. Task 2 assessed pain perceptual biases by measuring pain ratings to each single threshold (low intensity) and twice-threshold (high intensity) pain stimulus. RESULTS Results from task 1 indicated that higher FOP levels were associated with higher pain sensitivity when pain was appraised as a threat, reflected as high FOP group reporting higher pain intensity to those stimuli judged as painful in high threat condition than in low threat condition. Consistently, results from task 2 observed that when noxious stimulus intensity increased to threshold pain and twice threshold pain levels, high FOP group also generally reported higher pain intensity in high threat condition than in low threat condition. However, for both tasks, no such threat level differences were observed in low FOP group. CONCLUSIONS The current research emphasized that participants with higher FOP level showed pain perceptual biases to specific threatening painful stimulus. Threat appraisal of pain played a key role in the positive association between pain-related fear and pain perceptual biases. SIGNIFICANCE The findings highlight the modulatory influence of threat appraisal of pain in the positive association between pain-related fear and pain perceptual biases.

Abstract
BACKGROUND Pain-related cues are evolutionarily primed to capture attention, although evidence of attentional biases towards pain-related information is mixed in healthy individuals. The present study explores whether healthy individuals show significantly different eye-movement behaviours when viewing real-world pain-related scenes compared to neutral scenes. The effect of manipulating via written information the threat value of the pain-related scenes on eye-movement behaviours was also assessed. METHODS Participants were randomized to threatening (n = 28) and non-threatening (n = 27) information conditions. All completed a free-viewing task with real-world pain-related and neutral images while their eye movements were recorded. RESULTS Participants made significantly fewer fixations of significantly longer duration when viewing pain-related images compared to neutral images. No significant differences were found between threatening and non-threatening information groups in their pattern of eye movements. CONCLUSIONS This study shows that healthy individuals demonstrate attentional biases to pain-related real-world complex images compared to neutral images. Future research is needed to establish the implications of these biases, particularly in the context of acute pain, on the onset and/or subsequent maintenance of chronic pain conditions. SIGNIFICANCE Healthy individuals show different eye-movement behaviours when viewing pain-related scenes than neutral scenes, supporting evolutionary accounts of pain. Implications for the onset and/or maintenance of chronic pain need to be explored.

Abstract
Research into attentional biases and threatening, pain-related information has primarily been investigated using reaction time as the dependent variable. This study aimed to extend previous research to provide a more in depth investigation of chronic back pain and individuals’ attention to emotional stimuli by recording eye movement behavior. Individuals with chronic back pain (n = 18) were recruited from a back rehabilitation program and age and sex matched against 17 non-symptomatic controls. Participants’ eye movements were recorded whilst they completed a dot probe task, which included back pain specific threatening images and neutral images. There were no significant differences between chronic pain and control participants in attentional biases recorded using reaction time from the dot probe task. Chronic pain participants, however, demonstrated a significantly higher percentage of fixations, larger pupil diameter, a longer average fixation duration and faster first fixation to threatening compared to neutral images. They also had a significantly longer average fixation duration and larger pupil diameter to threatening images compared to control participants. The findings of this study suggest eye gaze metrics may provide a more sensitive measure of attentional biases in chronic pain populations. These findings may have important therapeutic implications for the patient and therapist.

Abstract
Empathy for pain is evolutionally important and context-dependent. The current study explored the effect of physical cue on 4- to 5-year-old children’s empathy for pain with two experiments. Experiment 1 investigated the effect of valid and invalid physical cue as compared to baseline (without cue) in pain evaluation task (evaluating the pain intensity of a facial expression, N = 28). Experiment 2 employed eye-tracking to investigate the attentional process in valid and baseline conditions (evaluating the pain intensity of a body image with an apparently injured arm or leg, N = 65). We found the evaluation of pain intensity was the highest in the valid condition, and higher in baseline condition than invalid. As for eye-tracking results, children fixated more quickly, had more fixations and longer total fixation duration in valid-cue condition. Of attention allocation, compared with baseline condition, children fixated on arm/leg more quickly, more frequently and for longer time in valid condition. Additionally, eye-tracking results were significantly related to their evaluation of pain intensity.

Abstract
Numerous behavior studies have assessed links of pain-related fear with biases in attention towards pain stimuli but considerably less is known about neural processes underlying such biases. To address this gap, event-related potentials (ERPs) were examined as 39 high pain-fearful (Hi-FOP) and 36 low pain-fearful (Lo-FOP) adults (1) viewed non-painful versus painful images and (2) subsequently received non-painful versus possibly painful somatosensory stimulation, respectively. The Hi-FOP group judged both non-painful and painful somatosensory stimulation to be more intense than Lo-FOP group members did. Hi-FOP group members also displayed smaller N1 amplitudes than Lo-FOP group members did during image presentations, regardless of image type. Finally, Lo-FOP group members exhibited larger P3 amplitudes when processing potentially painful somatosensory stimulation compared to non-painful stimulation while no such difference was observed in Hi-FOP group members. Overall results suggested that the pain-fearful tended to exaggerate the subjective intensity of potentially painful somatosensory stimuli but allocated comparatively fewer cognitive resources to processing such stimulation; arguably, this pattern perpetuates high fear of pain levels.

Abstract
The function of empathic concern to process pain is a product of evolutionary adaptation. Focusing on 5- to 6-year old children, the current study employed eye-tracking in an odd-one-out task (searching for the emotional facial expression among neutral expressions, N = 47) and a pain evaluation task (evaluating the pain intensity of a facial expression, N = 42) to investigate the relationship between children’s empathy and their behavioral and perceptual response to facial pain expression. We found children detected painful expression faster than others (angry, sad, and happy), children high in empathy performed better on searching facial expression of pain, and gave higher evaluation of pain intensity; and rating for pain in painful expressions was best predicted by a self-reported empathy score. As for eye-tracking in pain detection, children fixated on pain more quickly, less frequently and for shorter times. Of facial clues, children fixated on eyes and mouth more quickly, more frequently and for longer times. These results implied that painful facial expression was different from others in a cognitive sense, and children’s empathy might facilitate their search and make them perceive the intensity of observed pain on the higher side.

Abstract
BACKGROUND Studies have shown that specific cognitions and behaviours play a role in maintaining chronic fatigue syndrome (CFS). However, little research has investigated illness-specific cognitive processing in CFS. This study investigated whether CFS participants had an attentional bias for CFS-related stimuli and a tendency to interpret ambiguous information in a somatic way. It also determined whether cognitive processing biases were associated with co-morbidity, attentional control or self-reported unhelpful cognitions and behaviours. METHOD A total of 52 CFS and 51 healthy participants completed self-report measures of symptoms, disability, mood, cognitions and behaviours. Participants also completed three experimental tasks, two designed specifically to tap into CFS salient cognitions: (i) visual-probe task measuring attentional bias to illness (somatic symptoms and disability) v. neutral words; (ii) interpretive bias task measuring positive v. somatic interpretations of ambiguous information; and (iii) the Attention Network Test measuring general attentional control. RESULTS Compared with controls, CFS participants showed a significant attentional bias for fatigue-related words and were significantly more likely to interpret ambiguous information in a somatic way, controlling for depression and anxiety. CFS participants had significantly poorer attentional control than healthy individuals. Attention and interpretation biases were associated with fear/avoidance beliefs. Somatic interpretations were also associated with all-or-nothing behaviour and catastrophizing. CONCLUSIONS People with CFS have illness-specific biases which may play a part in maintaining symptoms by reinforcing unhelpful illness beliefs and behaviours. Enhancing adaptive processing, such as positive interpretation biases and more flexible attention allocation, may provide beneficial intervention targets.
