Mental time travel,memory and the social learning strategies tournament

The social learning strategies tournament was an open computer-based tournament investigating the best way to learn in a changing environment. Here we present an analysis of the impact of memory on the ability of strategies entered into the social learning strategies tournament (Rendell, Boyd, et al., 2010) to modify their own behavior to suit a changing environment. The tournament showed that a strategy's ability to remember the past and to predict the future were both key to its success. The possibility that a strategy needs to engage in an approximation of ‘mental time travel’ to succeed in the tournament strongly implies that investment in randomly timed social learning is not enough to guarantee success. A strategy must use social learning strategically with reference to both predicted future environmental states and past environmental states. We examine the two most successful strategies (DiscountMachine and Intergeneration) in terms of their use of memory and discuss the impact of their complex memory use on their ability to time learning moves strategically and track environmental change. The tournament suggests that the human capacity for mental time travel may have improved the efficiency of social learning and allowed humans to invest in more sophisticated social learning than is seen elsewhere in the animal kingdom.     

Perceptions of Training-Related Factors and Personal Variables as Predictors of Transfer Implementation Intentions

A number of factors influence the outcomes of computer skills training and the likelihood of successful transfer. The first empirical test of a conceptual model of training transfer sought to explain how trainees' perceptions of various in-training transfer-enhancing activities such as overlearning, fidelity, stimulus variability, principles-meaningfulness, self-management activities, relapse prevention, and goal setting would predict the self-efficacy and implementation intentions (rather than actual transfer outcomes) of computer skills trainees. As expected, posttraining self-efficacy and transfer enhancing activities both predicted transfer implementation intentions. Pretraining self-efficacy also significantly predicted posttraining self-efficacy, trainees' level of learning during training and transfer enhancing activities, providing support for the conceptual model of training transfer.     

Cognitive culture: theoretical and empirical insights into social learning strategies

Research into social learning (learning from others) has expanded significantly in recent years, not least because of productive interactions between theoretical and empirical approaches. This has been coupled with a new emphasis on learning strategies, which places social learning within a cognitive decision-making framework. Understanding when, how and why individuals learn from others is a significant challenge, but one that is critical to numerous fields in multiple academic disciplines, including the study of social cognition.     

Yoga,Mindfulness, and Meditation Interventions for Youth with ADHD: Systematic Review and Meta-Analysis

Attention-deficit/hyperactivity disorder (ADHD) is a chronic developmental disorder affecting 3–7% of children. In light of the growing utilization of yoga, mindfulness, and meditation in ADHD populations and potential benefits it has on ADHD symptoms, executive function deficits, and social functioning, we sought to evaluate these interventions for youth with ADHD. The primary aim of this review paper is to identify the efficacy of these programs for the treatment of youth with ADHD through a systematic review and meta-analysis. A systematic literature search was conducted in the following electronic databases: PsychINFO, ERIC, PubMed, and MEDLINE. Studies were included in the meta-analytic review if participants were between 5–17 years old, had a diagnosis of ADHD or met symptom threshold on psychometrically-validated measure of ADHD symptoms, was a treatment outcome study, and was published in a peer-reviewed English-language journal. The effect sizes of eleven studies demonstrate that yoga, mindfulness-based interventions, and/or meditation had a statistically significant effect on the outcomes of ADHD symptoms, hyperactivity, and inattention (parent and teacher report), as well as parent-child relationship, executive functioning, on-task behavior, parent stress, and parent trait-mindfulness (p?<?0.05). The effect sizes range from small to large effects across these outcomes. Considerable risk for bias was found across studies. Given significant methodological limitations of the literature, positive effect sizes found in studies should be interpreted with caution; these interventions should not be considered first-line interventions for ADHD. However, preliminary findings suggest yoga, mindfulness, and meditation may be beneficial for youth with ADHD, but extensive research is required to validate the efficacy of these interventions.

Paranoid thinking in mass shooters

Mass murderers, particularly school shooters, are depicted in the literature as either reacting with rage to taunts and bullying or as being psychopathic. However, examination of diaries and Web sites left by a subset of mass shooters (e.g., Eric Harris, Kimveer Gil, Seung-Hui Cho, Anders Breivik) reveals a different phenomenology than that typically proposed. This group greatly exaggerates the negativity of their treatment as reported by third-party school peers. They become and remain fixated and obsessed with rejection by what they see as an elite in-group whom they see as having unfairly achieved success. Instead of transcending the rejection, they formulate plans to annihilate the transgressors, which they justify as vengeance for the transgressions made against them. The self-exacerbating and obsessive qualities of these perceptions are more consistent with paranoid thinking than with psychopathy. The perceptions feed on themselves and, being part of a closed belief system, expand with time. In the rare cases where the perpetrator survives the mass shooting, they are diagnosed as paranoid schizophrenic. We focus on the pre-psychotic deterioration of their thinking.
