Divided attention enhances the recognition of emotional stimuli: evidence from the attentional boost effect

The present study examined predictions of the early-phase-elevated-attention hypothesis of the attentional boost effect (ABE), which suggests that transient increases in attention at encoding, as instantiated in the ABE paradigm, should enhance the recognition of neutral and positive items (whose encoding is mostly based on controlled processes), while having small or null effects on the recognition of negative items (whose encoding is primarily based on automatic processes). Participants were presented a sequence of negative, neutral and positive stimuli (pictures in Experiment 1, words in Experiment 2) associated to target (red) squares, distractor (green) squares or no squares (baseline condition). They were told to attend to the pictures/words and simultaneously press the spacebar of the computer when a red square appeared. In a later recognition task, stimuli associated to target squares were recognised better than stimuli associated to distractor squares, replicating the standard ABE. More importantly, we also found that: (a) the memory enhancement following target detection occurred with all types of stimuli (neutral, negative and positive) and (b) the advantage of negative stimuli over neutral stimuli was intact in the DA condition. These findings suggest that the encoding of negative stimuli depends on both controlled (attention-dependent) and automatic (attention-independent) processes.     

A Clinical Decision Support Tool to Predict Cancer Risk for Commonly Tested Cancer-Related Germline Mutations

The rapid drop in the cost of DNA sequencing led to the availability of multi-gene panels, which test 25 or more cancer susceptibility genes for a low cost. Clinicians and genetic counselors need a tool to interpret results, understand risk of various cancers, and advise on a management strategy. This is challenging as there are multiple studies regarding each gene, and it is not possible for clinicians and genetic counselors to be aware of all publications, nor to appreciate the relative accuracy and importance of each. Through an extensive literature review, we have identified reliable studies and derived estimates of absolute risk. We have also developed a systematic mechanism and informatics tools for (1) data curation, (2) the evaluation of quality of studies, and (3) the statistical analysis necessary to obtain risk. We produced the risk prediction clinical decision support tool ASK2ME (All Syndromes Known to Man Evaluator). It provides absolute cancer risk predictions for various hereditary cancer susceptibility genes. These predictions are specific to patients’ gene carrier status, age, and history of relevant prophylactic surgery. By allowing clinicians to enter patient information and receive patient-specific cancer risks, this tool aims to have a significant impact on the quality of precision cancer prevention and disease management activities relying on panel testing. It is important to note that this tool is dynamic and constantly being updated, and currently, some of its limitations include (1) for many gene-cancer associations risk estimates are based on one study rather than meta-analysis, (2) strong assumptions on prior cancers, (3) lack of uncertainty measures, and (4) risk estimates for a growing set of gene-cancer associations which are not always variant specific. All of these concerns are being addressed on an ongoing basis, aiming to make the tool even more accurate.     

Exploring the Link Between Mind Wandering,Mindfulness, and Creativity: A Multidimensional Approach

Even if mind wandering (MW) and mindfulness have traditionally been intended as separate and antithetical constructs, the roles of these 2 mental states on creative behavior were jointly explored in this article. In particular, MW was analyzed in light of a recent approach suggesting a differentiation between deliberate and spontaneous MW, whereas mindfulness was analyzed by distinguishing its 5 different constitutional dimensions: observing, acting with awareness, describing, nonreactivity, and nonjudging. The influence on creativity of these 2 mental states was analyzed using a sample of 77 undergraduate students both on a performance index (i.e., originality) and on a self-report index (i.e., creative achievement). Results showed that MW and mindfulness dimensions predicted creative behavior both alone and in combination, suggesting a complex interdependence between these 2 mental states within the creative thinking process. In particular, the critical importance of distinguishing between deliberate and spontaneous MW was revealed by a final path analysis, which revealed the opposite effects of these 2 dimensions on originality and creative achievement. That is, deliberate MW positively predicted creative performance, whereas spontaneous MW was negatively associated with such performance. Moreover, the nonreactivity and awareness dimensions of mindfulness, the latter in interaction with deliberate MW, emerged as main predictors of response originality. Finally, the describing facet of mindfulness predicted creative achievement both directly and indirectly through an interaction with deliberate MW. The implications emerging from the adoption of a multi-dimensional approach to the analysis of MW and mindfulness in the study of creativity are discussed herein.     

Patient Autonomy and Quality of Care in Telehealthcare

Telemedicine is a complex field including various applications and target groups. Especially telehealthcare is seen by many as a means to revolutionize medicine. It gives patients the opportunity to take charge of their own health by using self-tracking devices and allows health professionals to treat patients from a distance. To some, this means an empowerment of patient autonomy as well as an improvement in the quality of care. Others state the dangers of depersonalization of medicine and the pathologization of daily life. This paper examines the ethical implications of telehealthcare, focusing on patient autonomy and quality of care by analyzing metareviews, randomized controlled trials and narrative ethical analyses on the topic. As a result, we conclude that the technically enhanced encounter between patients and health professionals may mean an empowerment of patient autonomy when it goes along with a personal relationship based on trust, assistance and support. When it comes to the quality of care, telehealthcare may lead to an improvement as long it is adopted to the patient’s individual needs.     

Are belief‐based justifications associated with metalinguistic awareness? A cross‐sectional study in school‐age children

Previous research has consistently demonstrated that false‐belief (FB) understanding correlates with and predicts metalinguistic ability in preschoolers. Surprisingly, however, there is scant evidence on the question of whether this relation persists at later ages. The present cross‐sectional study sought to fill this gap by examining the association between FB understanding, belief‐based justifications and metalinguistic awareness. A sample of 150 children primary‐school children between 8 and 11 years of age were administered a test of receptive language, a second‐order theory‐of‐mind task and a comprehensive metalinguistic battery. The results of correlational and regression analyses showed that explicit metalinguistic awareness (in particular, performance in the Ambiguity and Phonemic Segmentation subtests) was significantly predicted by children's belief‐based responses to the justification question in the theory of mind task but only for children with small receptive vocabularies; in contrast, FB understanding made no independent contribution (either alone or in interaction with other measures). These findings complement and advance existing data by showing that, in school‐age children, the association between the 2 domains involves more mature, verbally explicit levels of FB understanding and metalinguistic awareness.

Highlights

• We examined the relation between metalinguistic awareness and theory‐of‐mind in primary‐school children.
• Metalinguistic awareness was associated to belief‐based justifications, but only for children with small vocabulary.
• In school‐age children the ability to provide verbal justifications plays a key role in the relation between theory‐of‐mind and metalinguistic awareness.

     

Do Personal Dispositions Affect the Relationship Between Psychosocial Working Conditions and Workplace Bullying?

There is scarce research on the interaction between psychosocial working conditions and being a target of workplace bullying with individual characteristics as a moderator. We therefore examined 3,363 employees from 60 Danish workplaces to test whether sense of coherence moderates the relationship between the job demand-control model and bullying. This work is exploratory in nature, as no previous study to assess this moderation was found. Hierarchical linear regressions showed that demand-control model was significantly associated with bullying. Sense of coherence displayed a significant though practically negligible moderating effect. This suggests that negative psychosocial working conditions are associated with bullying independently of personal characteristics, at least in terms of sense of coherence.     

Action observation network in childhood: a comparative fMRI study with adults

Very little is known about the action observation network and the mirror neuron system (AON/MNS) in children and its age‐related properties compared with those observed in adults. In the present fMRI study we explored the activation of areas belonging to the AON/MNS in children and adults during observation of complex hand‐grasping actions, as compared to observation of simple grasping acts executed with the left and the right hand, seen from a first person perspective. The results indicate that during the action observation tasks in children there was activation of a cortical network similar to that found in adults, including the premotor cortex, the posterior part of the inferior frontal gyrus and the posterior parietal lobe. However, the activation in children was more widespread and showed a higher inter‐subject variability compared with adults. Furthermore, the activated network seems more lateralized to the left hemisphere in adults and more bilateral in children, with a linear growth of lateralization index as a function of age. Finally, in children the activation in the anterior intraparietal cortex (AIP) of each hemisphere was higher during observation of the contralateral hand (hand identity effect) and during the observation of complex actions relative to simple grasping acts, confirming the role of AIP for action‐related hand identity previously described in adults. These results support the assumption that structure and size of action representations are sensitive to mechanisms of development and show physiological plasticity. These properties of the AON/MNS could constitute a powerful tool for spontaneous reorganization and recovery of motor deficits after brain injury in children and in adults, as well as for specific rehabilitation programmes.

Relations between theory of mind,mental state language and social adjustment in primary school children

The present study investigated the concurrent relations between theory of mind (ToM), mental state language (MSL) and social adjustment (assessed in terms of emotional instability, prosocial behaviour and aggressiveness) in a sample of 150 children between 8 and 11 years of age. The results showed no correlation between the performance on false belief tasks and the frequency of MSL in a narrative task. False belief understanding was unrelated with all measures of social adjustment, whereas the children’s use of MSL was negatively correlated with emotional instability and aggressiveness, above and beyond the influence of receptive language ability. These findings suggest that having a ToM ability is different from spontaneously using it during non-interactive narrative tasks, and that the two ToM measures are differently related to social competence in primary school children.     

Spatial attention can be biased towards an expected dimension

A commonly held view in both exogenous and endogenous orienting is that spatial attention is associated with enhanced processing of all stimuli at the attended location. However, we often search for a specific target at a particular location, so an observer should be able to jointly specify the target identity and expected location. Whether attention can bias dimension-specific processes at a particular location is not yet clear. We used a dual task to examine the effects of endogenous spatial cues on the accuracy of perceptual judgments of different dimensions. Participants responded to a motion target and a colour target, presented at the same or different locations. We manipulated a central cue to predict the location of the motion or colour target. While overall performance in the two tasks was comparable, cueing effects were larger for the target whose location was predicted by the cue, implying that when attending a particular location, processing of the likely dimension was preferentially enhanced. Additionally, an asymmetry between the motion and colour tasks was seen; motion was modulated by attention, and colour was not. We conclude that attention has some ability to select a dimension at a particular location, indicating integration of spatial and feature-based attention.
