Attentional Bias Modification Training Based on Virtual Reality and Eye Tracking in Anorexia Nervosa Patients.

Anorexia nervosa (AN) patients exhibit attentional bias (AB) related to the body, which is the tendency to pay greater attention to weight-related body areas compared to non-weight-related ones. This phenomenon has been linked to elevated levels of body dissatisfaction (BD) and may potentially reduce the effectiveness of body exposure therapy. The purpose of this pilot study is to assess the efficacy of a single session of a new body-related AB modification task (ABMT) that combines virtual reality with eye tracking in patients with AN. The goals of the ABMT are to reduce body-related AB by balancing attention between weight and non-weight-related body areas and to reduce BD levels. Twenty-three adolescent patients with AN were embodied in a virtual avatar and immersed in a virtual environment where they completed the ABMT. Body-related AB measures and BD levels were assessed before and after the training. A paired samples t-test showed statistically significant differences between pre-assessment and post-assessment; the complete fixation time on weight-related body parts was reduced and BD levels decreased. The initial evidence of the efficacy of this ABMT has important clinical implications, since AB and BD are considered risk factors for developing and maintaining eating disorder symptomatology among patients with AN.

An Attentional Bias Modification Task, through Virtual Reality and Eye-Tracking Technologies, to Enhance the Treatment of Anorexia Nervosa.

Mirror exposure therapies (METs) have been shown to be effective in reducing body image disturbances through the habituation process. Virtual reality (VR) combined with eye-tracking techniques can provide innovative solutions to some of METs' limitations reported with patients with anorexia nervosa (AN), especially the negative influence of body-related attentional bias (AB). This pilot study aimed to assess the preliminary efficacy of a new VR-based AB modification task (ABMT) among healthy women and the procedure's user experience. AB levels towards weight- and non-weight-related body parts, using complete fixation time (CFT) and number of fixations (NF), were assessed throughout the ABMT procedure (300 trials). The user experience was evaluated at the end of the procedure. The results showed that VR-based ABMT was effective in reducing AB significantly after 150 trials for both CFT- and NF-based measures, although 225 trials were necessary to get the same result for women with an NF initially more oriented towards weight-related body parts. Overall, the software received a "C-rating" on a scale from "A" (most usable) to "F" (least usable). These results provide evidence of the opportunity to use a VR-based ABMT procedure to reduce AB and improve existing treatments for AN.

Relationship Between Attention Bias and Psychological Index in Individuals With Chronic Low Back Pain: A Preliminary Event-Related Potential Study.

Introduction: Attention bias towards pain-related information exists in patients with chronic pain, and recently, attention bias modification (ABM) training has been administered to patients with chronic pain. In this study, we conducted an attention bias modification task in conjunction with event-related potential measurements for individuals with chronic low back pain (LBP) and investigated the relationship between attention bias and psychological assessment.Methods: Eleven women and two men with chronic LBP participated in the study.Results: The Japanese version of the STarT Back Screening Tool (J-SBST) total score was significantly correlated with the N1 amplitude of Cz. The J-SBST psychological score was significantly correlated with the N1 amplitude of Cz and with reaction time (RT). The Japanese version of the Pain Catastrophizing Scale (PCS) and Japanese version of the Beck Depression Inventory-Second Edition (BDI-II) scores were significantly correlated with the P2 amplitude at Fz (only PCS), Cz, and Pz.Conclusions: Our findings suggest that J-SBST, which provides a comprehensive evaluation of psychological factors, PCN with measuring of catastrophizing in the context of actual or anticipated pain, and BDI-II, can likely help identify chronic LBP patients with attention bias. For chronic LBP patients who are classified according to J-SBST or PCN pain-related outcome improvement with ABM training can be expected.

Emotion-in-Motion, a Novel Approach for the Modification of Attentional Bias: An Experimental Proof-of-Concept Study.

BackgroundIndividuals with heightened anxiety vulnerability tend to preferentially attend to emotionally negative information, with evidence suggesting that this attentional bias makes a causal contribution to anxiety vulnerability. Recent years have seen an increase in the use of attentional bias modification (ABM) procedures to modify patterns of attentional bias; however, often this change in bias is not successfully achieved.ObjectiveThis study presents a novel ABM procedure, Emotion-in-Motion, requiring individuals to engage in patterns of attentional scanning and tracking within a gamified, complex, and dynamic environment. We aimed to examine the capacity of this novel procedure, as compared with the traditional probe-based ABM procedure, to produce a change in attentional bias and result in a change in anxiety vulnerability.MethodsWe administered either an attend-positive or attend-negative version of our novel ABM task or the conventional probe-based ABM task to undergraduate students (N=110). Subsequently, participants underwent an anagram stressor task, with state anxiety assessed before and following this stressor.ResultsAlthough the conventional ABM task failed to induce differential patterns of attentional bias or affect anxiety vulnerability, the Emotion-in-Motion training did induce a greater attentional bias to negative faces in the attend-negative training condition than in the attend-positive training condition (P=.003, Cohen d=0.87) and led to a greater increase in stressor-induced state anxiety faces in the attend-negative training condition than in the attend-positive training condition (P=.03, Cohen d=0.60).ConclusionsOur novel, gamified Emotion-in-Motion ABM task appears more effective in modifying patterns of attentional bias and anxiety vulnerability. Candidate mechanisms contributing to these findings are discussed, including the increased stimulus complexity, dynamic nature of the stimulus presentation, and enriched performance feedback.

A neuromarker of clinical outcome in attention bias modification therapy for social anxiety disorder.

Attention bias modification (ABM) therapy aims to modify threat-related attention patterns via computerized tasks. Despite showing medium clinical effect sizes for anxiety disorders, underlying neural-cognitive mechanisms of change remain unclear. We used visual mismatch negativity (vMMN), an event-related potential sensitive to violations of learned statistical contingencies, to assess therapy-related contingency extraction processes in healthy participants and in patients with social anxiety disorder (SAD). We then assessed whether vMMN amplitude predicts ABM treatment outcome. A modified version of the dot-probe task was used to elicit vMMN, in which 80% of trials were standard and 20% were deviant. In study 1, 30 healthy adults were randomly assigned to one of two ABM conditions: one in which threat-congruent targets were deviant trials and threat-incongruent targets were standard trials, and another in which the contingency was reversed. Electroencephalography (EEG) was continuously measured and vMMN analyzed. In study 2, 38 patients with SAD underwent six sessions of ABM therapy. We tested whether rule extraction in the ABM task, indicated by vMMN amplitude, predicts treatment outcome. vMMN clearly emerged over prespecified scalp locations indicating contingency extraction during ABM (study 1). vMMN amplitude predicted clinical improvement after ABM therapy, uniquely accounting for 7% and 14.4% of the variance in clinician-rated and self-reported posttreatment SAD symptoms, respectively. vMMN emerges as a neural marker for contingency learning in ABM, suggesting a significant role for contingency extraction processes in the clinical efficacy of this therapy.

Attention bias for appearance words can be reduced in women: Results from a single-session attention bias modification task

Background and ObjectivesWe tested whether a single-session of attention bias modification (ABM) could change bias towards appearance-related words and improve body satisfaction. MethodsFemales (N = 102; Mage = 33 years) completed an ABM session where attention was trained towards positive appearance-related information (n = 31), away from negative appearance-related information (n = 37), or a non-training session (n = 34). Importance of appearance and shape concern were examined as moderators. ResultsABM was effective in women high on appearance importance, trained to direct attention away from negative appearance words. LimitationsNo long-term follow up of attention biases or body image challenge were conducted. ConclusionsThese findings suggest that certain types of attention biases are amenable to change within a single session.

The Improvement of Mothers’ and Children’s Emotional and Behavioral Reactions through the Modification of Attentional Bias in Mothers: A Micro-Trial Study

SYNOPSISObjective. The aim of this study was to test whether and to what extent inducing attentional bias in mothers toward a child’s positive emotions using a micro-trial method would improve mothers’ emotional and behavioral reactions in parenting-related situations. Effects on children were also assessed. Design. Forty-two mothers of 4- to 5-year-old children participated. Half of the mothers were exposed to an attention bias modification task designed to elicit a transient bias toward positive stimuli. After the manipulation, they were observed during a free-play session and frustration laboratory tasks designed to elicit positive and negative emotions. Results. Mothers exposed to the attention bias modification task displayed more positive emotional and behavioral reactions toward their child during both free-play and frustration tasks. Their children also behaved better, especially during the free-play session. The influence of mothers’ attention allocation on children’s outcomes was mediated by mothers’ behavior. Conclusions. An attention bias modification program is useful in improving interactions between mothers and children.

The application of virtual reality technology in the training of peer interaction in children with high functioning autism: attentional bias modification

Objective To explore the effect of virtual reality technology in the promotion of peer interaction ability in children with high functioning autism(HFA). Methods 15 children with HFA were recruited and divided into control group(n=5), experimental group 1(n=5)and experimental group 2(n=5)with IQ and gender matching. The experimental group 1 received the attentional bias modification task, the flash animation technology task using virtual reality technology and the task in the real environment. The experimental group 2 received the flash animation technology task using virtual reality technology and the task in the real environment. The control group received the task in the real environment only. Results (1)After the attentional bias modification, compared with the experimental group 2, the experimental group 1 was shorter on reaction time(T1=16.0, T2=39.0, U=1.0, P=0.016), and was higher on the accuracy(T1=40.0, T2=15.0, U=0.0, P=0.008). (2)The scores of the experimental group 1 in the other-regarding(T1=39.5, T2=15.5, U=0.5, P<0.01)and the using language(T1=38.0, T2=17.0, U=2.0, P<0.05) were higher than the experimental group 2.(3) The scores of the experimental group 1 in the other-regarding, using language and rule executor were higher than those of the control group(all P<0.01). (4) The score of the experimental group 2 in the other-regarding was higher than that of the control group(P<0.05). Conclusion The attention bias correction based virtual reality peer interaction technology can effectively improve the ability of other-regarding, language using and execution rules of children with HFA in the real environment. Key words: High functioning autism; Peer interaction; Attentional bias; Virtual reality technology; Real environment

The Potential Benefits of Targeted Attentional Bias Modification on Cognitive Arousal and Sleep Quality in Worry-Related Sleep Disturbance

Attentional bias for sleep-related negative information is believed to contribute to symptoms of insomnia by elevating arousal during the presleep period. In the present study, we examined whether the delivery of an attentional bias modification (ABM) procedure in the presleep period could produce transient benefits for sleep-disturbed individuals by reducing presleep cognitive arousal and improving ease of sleep onset. In a counterbalanced repeated A-B design, participants alternated completing an ABM training task and a nontraining control task across six nights and reported on presleep cognitive arousal and sleep onset latency. Significant reductions in presleep cognitive arousal and sleep onset latency were observed on nights where the ABM task was completed relative to nights where the control task was completed. These results suggest that delivery of ABM can attenuate cognitive arousal and sleep onset latency and highlights the possibility that targeted delivery of ABM could deliver real-world benefits for sleep-disturbed individuals.

Can't Look Away: An Eye-Tracking Based Attentional Disengagement Training for Depression.

To address shortcomings of purely reaction-time based attentional bias modification (ABM) paradigms, we developed an ABM task that is controlled by eye-tracking. This task allows to assess and train both disengagement from negative pictures and maintained attention to positive pictures. As a proof-of-principle study with an unselected student sample, this positive training (PT; N = 44) was compared to a negative training (NT; N = 42), which reinforced the opposite attentional pattern. Importantly, training trials were completed only if participants performed the correct gaze patterns. Results showed that higher depression levels were associated with slower disengagement from negative stimuli at baseline. As expected, the PT induced longer fixations on positive pictures and faster disengagement from negative pictures. The NT showed no changes in attentional processes. The groups did not differ in mood reactivity and recovery from a stressor. Advantages of using eye-tracking in ABM and potential applications of the training are discussed.

Attentional bias and treatment adherence in substitute-prescribed opiate users

BackgroundAttentional bias (AB) is implicated in the development and maintenance of substance dependence and in treatment outcome. We assessed the effects of attentional bias modification (ABM), and the relationship between AB and treatment adherence in opiate dependent patients. MethodAn independent groups design was used to compare 23 opiate dependent patients with 21 healthy controls. Participants completed an AB task before either a control or an ABM task designed to train attention away from substance-related stimuli. Pre- and post-ABM AB and craving were assessed to determine any changes. Relationships between treatment adherence (‘using on top’ of prescribed opiates or not) and AB, craving and psychopathology were also examined. ResultsThere was no baseline difference in AB between patients and controls, and no significant effect of ABM on AB or substance craving. However, treatment adherent patients who did not use illicit opiates on top of their prescribed opiates had statistically significantly greater AB away from substance-related stimuli than both participants using on top and controls, and reported significantly lower levels of craving than non-treatment adherent patients. ConclusionWhilst we did not find any significant effects of ABM on AB or craving, patients who were treatment adherent differed from both those who were not and from controls in their attentional functioning and substance craving. These findings are the first to suggest that AB may be a within-treatment factor predictive of adherence to pharmacological treatment and potentially of recovery in opiate users.

Validation of a novel attentional bias modification task: The future may be in the cards

Attentional bias modification (ABM) is a promising therapeutic tool aimed at changing patterns of attentional selectivity associated with heightened anxiety. A number of studies have successfully implemented ABM using the modified dot-probe task. However others have not achieved the attentional change required to achieve emotional benefits, highlighting the need for new ABM methods. The current study compared the effectiveness of a newly developed ABM task against the traditional dot-probe ABM task. The new person-identity-matching (PIM) task presented participants with virtual cards, each depicting a happy and angry person. The task encourages selective attention toward or away from threat by requiring participants to make matching judgements between two cards, based either on the identities of the happy faces, or of the angry faces. Change in attentional bias achieved by both ABM tasks was measured by a dot-probe assessment task. Their impact on emotional vulnerability was assessed by measuring negative emotional reactions to a video stressor. The PIM task succeeded in modifying attentional bias, and exerting an impact on emotional reactivity, whereas this was not the case for the dot-probe task. These results are considered in relation to the potential clinical utility of the current task in comparison to traditional ABM methodologies.

The Causal Role of the Dorsolateral Prefrontal Cortex in the Modification of Attentional Bias: Evidence from Transcranial Direct Current Stimulation

A pattern of attentional bias for threatening information is thought to be involved in the etiology of anxiety. Consistent with this idea, cognitive training techniques directly targeting such patterns of biased attention have been shown to reduce symptoms of anxiety. Research seeking to establish the neurologic underpinnings of change in the attentional bias for threat have implicated, but not confirmed, the role of lateral prefrontal regions. The current study sought to confirm experimentally the causal role of lateral prefrontal areas in the modification of attentional bias by delivering targeted cortical stimulation during attention bias modification training to assess the consequent effects on attentional bias change. While completing either an "attend threat" or "avoid threat" attention bias modification task, 77 volunteers (17-22 per group) received either active transcranial direct current stimulation of the left dorsolateral prefrontal cortex or a sham stimulation control condition. Participants receiving active stimulation showed greater evidence of attentional bias acquisition in the targeted direction (toward or away from threat) compared with participants in the sham stimulation condition. Our findings provide the first experimental evidence that increasing activity in the dorsolateral prefrontal cortex leads to greater evidence of attention bias modification. This evidence confirms the role of these areas in facilitating change in the allocation of attention to threat. We believe this study provides a critical step in the translation of neuroimaging findings to novel neuromodulatory interventions capable of enhancing the treatment of emotional pathology.

Attention bias for chocolate increases chocolate consumption – An attention bias modification study

ObjectiveThe current study examined experimentally whether a manipulated attention bias for food cues increases craving, chocolate intake and motivation to search for hidden chocolates. MethodTo test the effect of attention for food on subsequent chocolate intake, attention for chocolate was experimentally modified by instructing participants to look at chocolate stimuli (“attend chocolate” group) or at non-food stimuli (“attend shoes” group) during a novel attention bias modification task (antisaccade task). Chocolate consumption, changes in craving and search time for hidden chocolates were assessed. Eye-movement recordings were used to monitor the accuracy during the experimental attention modification task as possible moderator of effects. Regression analyses were conducted to test the effect of attention modification and modification accuracy on chocolate intake, craving and motivation to search for hidden chocolates. ResultsResults showed that participants with higher accuracy (+1 SD), ate more chocolate when they had to attend to chocolate and ate less chocolate when they had to attend to non-food stimuli. In contrast, for participants with lower accuracy (−1 SD), the results were exactly reversed. No effects of the experimental attention modification on craving or search time for hidden chocolates were found. LimitationWe used chocolate as food stimuli so it remains unclear how our findings generalize to other types of food. ConclusionThese findings demonstrate further evidence for a link between attention for food and food intake, and provide an indication about the direction of this relationship.
