Adolescents’ engagement with social media

Social media plays an increasingly important role in the daily lives of adolescents. Yet evidence of its effects are mixed, and the field lacks underlying theory to guide more nuanced research. This study explored the psychosocial processes underpinning adolescent engagement with social media. Adolescents (n = 28) were interviewed regarding their experiences of social media, and interview transcripts were analysed using grounded theory methodology. The emergent theory describes a cyclical process of evaluating the risks vs rewards of social media use, experimenting, learning from experiences, and re-calibrating one’s stance towards social media. Two styles of use, active and passive, became apparent, each maintained and defended by numerous strategies employed consciously and unconsciously, with the overarching goal of maintaining a sense of safety regarding their sense of self and status within their social hierarchy. This study depicts a complex, nuanced picture of adolescent engagement with SM, one that encompasses both positive and negative experiences. The model points to the importance of identity and social identity theories, and raises important questions about identity development in this evolving context

Adaptive working memory training reduces the negative impact of anxiety on competitive motor performance

Optimum levels of attentional control are essential to prevent athletes from experiencing performance breakdowns under pressure. The current study explored whether training attentional control using the adaptive dual n-back paradigm, designed to directly target processing efficiency of the main executive functions of working memory (WM), would result in transferrable effects on sports performance outcomes. A total of 30 tennis players were allocated to an adaptive WM training or active control group and underwent 10 days of training. Measures of WM capacity as well as performance and objective gaze indices of attentional control in a tennis volley task were assessed in low- and high-pressure posttraining conditions. Results revealed significant benefits of training on WM capacity, quiet eye offset, and tennis performance in the high-pressure condition. Our results confirm and extend previous findings supporting the transfer of cognitive training benefits to objective measures of sports performance under pressure

The effects of adaptive working memory training and mindfulness meditation training on processing efficiency and worry in high worriers

Worry is the principle characteristic of generalised anxiety disorder, and has been linked to deficient attentional control, a main function of working memory (WM). Adaptive WM training and mindfulness meditation practice (MMP) have both shown potential to increase attentional control. The present study hence investigates the individual and combined effects of MMP and a dual adaptive n-back task on a non-clinical, randomised sample of high worriers. 60 participants were tested before and after seven days of training. Assessment included self-report questionnaires, as well as performance tasks measuring attentional control and working memory capacity. Combined training resulted in continued reduction in worry in the week after training, highlighting the potential of utilising n-back training as an adjunct to established clinical treatment. Engagement with WM training correlated with immediate improvements in attentional control and resilience, with worry decreasing over time. Implications of these findings and suggestions for future research are discussed

Training cognitive control to reduce emotional vulnerability in breast cancer

Objectives: Breast cancer enhances anxiety and depressive vulnerability, profoundly impairing the quality of life in survivors. Hinging on recent research that training attentional control can reduce emotional vulnerability, we assess how improving cognitive function could reduce emotional vulnerability in female survivors of breast cancer. Methods: Participants took part in a course of adaptive dual n-back cognitive training (Training Group) or a non-adaptive active control group (Active Control) for 12 days across a two-week period. Transfer-related training gains were assessed immediately after the intervention, at a shorter one-month follow-up and at a longer follow-up time of approximately 15 months post intervention, to assess sustainability of training effects. Results: Adaptive cognitive training reduced anxiety and rumination with effects evident at shorter and longer term follow-up assessments. Conclusions: Our results are amongst the first to suggest that adaptive cognitive training can reduce emotional vulnerability in breast cancer, with the potential to enhance quality of life in survivorship. Our findings have profound implications for designing interventions targeting cognitive function in populations who’ve suffered from cancer

Social media use and adolescent well-being: A narrative review of longitudinal studies

This article provides a narrative review of longitudinal studies investigating the impact of social media (SM) use on adolescent well-being from 2006 to 2019. A topic of popular concern, most research to date has been cross-sectional, limiting the inferences that can be drawn to correlational observations. Longitudinal studies add valuable input to extant scholarship, and they have begun to emerge in the literature. A systematic search of PsychINFO, Web of Science, and Assia conducted in January 2019 identified 14 papers meeting inclusion criteria. The article summarizes the evidence and highlights emerging trends. Most notably, research distinguishing type of SM use, as opposed to mere frequency of SM use, is producing more significant results, suggesting a need for study designs that are able to capture the complexities of SM engagement beyond time spent online. The review also sets out the limitations of the current studies, which include unvalidated, self-report exposure measures and a failure to consider conditional effects. Addressing these challenges will present avenues for future research

Personalized cognitive training: Protocol for individual-level meta-analysis implementing machine learning methods

Accumulating evidence suggests that cognitive training may enhance well-being. Yet, mixed findings imply that individual differences and training characteristics may interact to moderate training efficacy. To investigate this possibility, the current paper describes a protocol for a data-driven individual-level meta-analysis study aimed at developing personalized cognitive training. To facilitate comprehensive analysis, this protocol proposes criteria for data search, selection and pre-processing along with the rationale for each decision. Twenty-two cognitive training datasets comprising 1544 participants were collected. The datasets incorporated diverse training methods, all aimed at improving well-being. These training regimes differed in training characteristics such as targeted domain (e.g., working memory, attentional bias, interpretation bias, inhibitory control) and training duration, while participants differed in diagnostic status, age and sex. The planned analyses incorporate machine learning algorithms designed to identify which individuals will be most responsive to cognitive training in general and to discern which methods may be a better fit for certain individuals

Attentional control and cognitive biases as determinants of vulnerability and resilience in anxiety and depression

Book synopsis: Cognitive Biases in Health and Psychiatric Disorders: Neurophysiological Foundations focuses on the neurophysiological basis of biases in attention, interpretation, expectancy and memory. Each chapter includes a review of each specific bias, including both positive and negative information in both healthy individuals and psychiatric populations. This book provides readers with major theories, methods used in investigating biases, brain regions associated with the related bias, and autonomic responses to specific biases. Its end goal is to provide a comprehensive overview of the neural, autonomic and cognitive mechanisms related to processing biases
