When Less Is More: Investigating Factors Influencing the Distraction Effect of Virtual Reality From Pain

Virtual reality (VR) is a powerful method of redirecting attention away from pain. Yet, little is known about which factors modulate the size of this distraction effect. The aim of this study was to investigate the role of cognitive load and inter-individual differences in the cognitive and affective domain on heat pain thresholds during a VR game. Ninety healthy participants (mean age ± SD: 23.46 ± 3.28; 50% identified as male and 50% as female) played a low and high load version of a VR game while heat pain thresholds and heart rate were recorded. The effects of cognitive load were assessed by computing the difference in pain thresholds between the high and low load condition for each participant. In addition, we computed the difference in heart rate variability (HRV) measures between both conditions to explore whether these would be correlated with the difference in heat pain thresholds. Prior to the VR session, participants completed questionnaires about their emotional distress, pain-related cognitions, and different executive functioning tasks. Contrary to our expectations, not all participants benefitted from a higher load in terms of distraction from pain. Logistic regression analysis revealed that participants who reported more emotional distress were more likely to exhibit higher pain thresholds in the low relative to the high load condition. Accordingly, these participants tended to show marginally higher HRV in the low compared to the high load condition. Our study demonstrates that the potential benefits of an increased cognitive load in VR on pain sensitivity depends on individual differences in affective state.

The Role of Attentional Bias in Excessive Food Consumption

<p>New Zealand obesity rates have reached epidemic proportions. Excessive eating not only harms individual health, but also the NZ economy; health-related costs soar with rising obesity rates. The need to understand possible mechanisms driving excessive eating behaviour is now crucial. One cognitive mechanism thought to contribute to excessive eating is an attentional bias towards food stimuli. We propose this bias would be similar to the attentional bias that is consistently shown with emotional stimuli (e.g. erotic and mutilation images). In this thesis I examined attentional biases towards food stimuli and how they relate to both state (hunger) and trait (waist circumference) factors. In Experiment 1, I investigated the existence of a food-related attentional bias and whether this bias is stronger towards high calorie food images, compared to low-calorie and non-food images (household objects). Participants were asked to fast for 2 hours (to promote self-reported hunger) before completing a distraction task. This task has repeatedly shown an attentional bias to high arousal emotional images (erotic and mutilation scenes). On each trial, participants had to determine whether a target letter was a ‘K’ or an ‘N’, while ignoring centrally-presented distractors (high calorie, low calorie and household object images). Compared to scrambled images, all image types were similarly distracting. We found no support for the existence of an attentional bias towards food stimuli; nor did we find a significant association between the bias and either state or trait factors. Experiment 2 sought to conceptually replicate Cunningham & Egeth (2018) who found significant support for the existence of a food-related attentional bias. Participants completed a similar task. However, distractor relevance was manipulated by incorporating both central and peripheral distractors, to increase ecological validity. Additionally, participants were asked to fast for longer (4 hours) to increase self-reported hunger. Despite a significant distraction effect (participants were more distracted on distractor present vs. distractor absent trials) and distractor-location effect (participants were more distracted by central vs. peripheral distractors), participants did not exhibit an attentional bias towards food stimuli. Furthermore, no significant associations between the bias and either state or trait factors were found. Thus, food stimuli do not appear to rapidly capture attention the way that emotional stimuli do, at least not in this task. Future research is needed to clarify the role of cognitive mechanisms in excessive eating behaviour.</p>

Does Protest “Distract” Athletes From Performing? Evidence From the National Anthem Demonstrations in the National Football League

While there is a long tradition of activism within sport, a popular criticism of athlete protest is that it is a “distraction” that hinders on-field performance. The widespread demonstrations against racial injustice in 2017 among players in the National Football League (NFL) provided an opportunity to test this “distraction hypothesis.” Using data drawn from multiple sources, we first explored which factors predicted player protest, finding that Black players and those playing for underdogs were more likely to protest. Then, using a series of analyses at the player-game level ( n = 19,051) and the team-game level ( n = 512), we tested the assertion that protest is detrimental to individual or team performance, finding no evidence for a distraction effect. The results of this study allow us to better understand social factors that may affect athletic performance or constrain athlete activism.

Attentional control in middle childhood is highly dynamic - Strong initial distraction is followed by advanced attention control

The ability to shield against distraction while focusing on a task requires the operation of executive functions and is essential for successful learning. We investigated the short-term dynamics of distraction control in a data set of 269 children aged 4–10 years and 51 adults pooled from three studies using multilevel models. Participants performed a visual categorization task while a task-irrelevant sequence of sounds was presented which consisted of frequently repeated standard sounds and rarely interspersed novel sounds. On average, participants responded slower in the categorization task after novel sounds. This distraction effect was more pronounced in children. Throughout the experiment, the initially strong distraction effects declined to level of adults in the groups of 6- to 10-year-olds. Such a decline was neither observed in the groups of the 4- and 5-year-olds, who consistently show a high level of distraction, nor in adults, who showed a constantly low level of distraction throughout the experimental session. Results indicate that distraction control is a highly dynamic process that qualitatively and quantitatively differs between age groups.We conclude that the analysis of short-term dynamics provides valuable insights into the development of attention control and might explain inconsistent findings regarding distraction control in middle childhood. In addition, models of attention control need to be refined to account for age-dependent rapid learning mechanisms. Our findings have implications for the design of learning situations and provide an additional source of information for diagnosis and treatment of attention deficit disorders.

Sown Wildflowers Enhance Habitats of Pollinators and Beneficial Arthropods in a Tomato Field Margin

We evaluated the capacity of selected plants, sown along a processing tomato field margin in central Greece and natural vegetation, to attract beneficial and Hymenoptera pollinating insects and questioned whether they can distract pollinators from crop flowers. Measurements of flower cover and attracted pollinators and beneficial arthropods were recorded from early-May to mid-July, during the cultivation period of the crop. Flower cover was higher in the sown mixtures compared to natural vegetation and was positively correlated with the number of attracted pollinators. The sown Glebionis coronaria, Coriandrum sativum, Anethum graveolens, and Fagopyrum esculentum attracted mainly wild bees, which were the most abundant pollinating insects. In the natural vegetation, Rapistrum rugosum attracted mainly honeybees, while Asteraceae, Convolvulaceae, and Apiaceae species attracted wild bees. Beneficial arthropod abundance and diversity were higher in the sown mixture. Tomato flowers were visited by a small number of wild bees. Their number was not affected by the distance from the field margin, indicating no distraction effect from the sown or natural vegetation flowering plants. Our results suggest that selected flowering plants can improve the field margin habitats for pollinating insects and beneficial arthropods, but more work is needed to elucidate the effect on crop pollination.

Manipulative Shallow Processing Induced by Presuppositions and Topics: Theoretical Perspectives and Experimental Evidence

The paper shows that implicit strategies for questionable contents are frequent in persuasive texts, as compared to texts with other purposes. It proposes that the persuasive and manipulative effectiveness of introducing questionable contents implicitly can be explained through established cognitive patterns, namely that what is felt by addressees as information coming (also) from them and not (only) from the source of the message is less likely to be challenged. These assumptions are verified by showing examples of “implicitness of evidential responsibility” (essentially, presuppositions, and topics) as triggers of lesser attention in advertising and propaganda. A possible evolutionary path is sketched for three different pragmatic functions of presuppositions, leading to their availability for manipulation. The distraction effect of presuppositions and topics is also explained in relation with recent developments of Relevance Theory. Behavioral evidence that presuppositions and topics induce low epistemic vigilance and shallow processing is compared to recent neurophysiological evidence which does not confirm this assumption, showing greater processing costs for presuppositions and topics as compared to assertions and foci. A proposal is put forward to reconcile these apparently contrasting data and to explain why they may not be in contrast after all. Also due to natural language quick processing constraints (a “Now-or-Never processing Bottleneck”), effort devoted to accommodation of presupposed or topicalized new contents may drain resources from concurrent epistemic vigilance and critical evaluation, resulting in shallower processing.

Story Telling as Therapeutic Intervention Toward Anxiety Level: A Literature Review

Anxiety is one of the common psychological symptoms experienced by children while being treated in the hospital and can cause impairment in growth and development. Hospitalization is considered threatening and has traumatic effects, which can be mitigated using various therapies. Storytelling is one of the therapeutic intervention methods. The purpose of this literature review is to explore the effectiveness of storytelling among preschool children who undergo hospitalization. Literature research conducted on the five largest databases consists of PubMed, Google Scholar, CINAHL, Medline, and PsycINFO using keywords, “Story Telling,” “Hospitalization,” “Anxiety Level,” “Preschool,” and “Story Telling and Hospitalization.” The combination of keywords searches to find more specific literature. We found 25 articles, and five articles are analyzed further. Storytelling is proven effective for reducing the impact of hospitalization, especially anxiety levels for preschool children. It provides a distraction effect and opportunity to develop imagination, opening children mind it and perception or feelings of fear. It is suggested that healthcare professionals implement this intervention to minimize the physical and psychological effects of hospitalization.
