The present paper reports a pilot study which tested cognitive effects of mindfulness practice in a theory-driven approach. Thirty-four fifth graders received either a mindfulness training which was based on the mindfulness-based stress reduction approach (experimental group), a concentration training (active control group), or no treatment (passive control group). Based on the operational definition of mindfulness by Bishop et al. (2004), effects on sustained attention, cognitive flexibility, cognitive inhibition, and data-driven as opposed to schema-based information processing were predicted. These abilities were assessed in a pre-post design by means of a vigilance test, a reversible figures test, the Wisconsin Card Sorting Test, a Stroop test, a visual search task, and a recognition task of prototypical faces. Results suggest that the mindfulness training specifically improved cognitive inhibition and data-driven information processing.

The present study examined the effects of mindfulness training on attention regulation in university students and whether the potential benefits of implementation are influenced by the yoga component of mindfulness-based interventions (MBIs) and/or by MBI homework practice. In a non-randomized trial with pre-and post-assessments, n = 180 university students were allocated to either mindfulness training (experimental groups), awareness activities (active control group), or no training (passive control group). Mindfulness was taught through two MBIs, one including yoga and the other excluding yoga. Attention regulation was operationalized via behavioral indicators, namely sustained attention, cognitive flexibility, cognitive inhibition, and data-driven information processing. With the exception of speed in a cognitive flexibility task, the results indicated no systematic or differential advantage arising from mindfulness training, with or without yoga, regarding the aspects of attention regulation. There was no consistent influence of homework quantity or quality. The implications for mindfulness training in academic contexts are discussed.

Background/Objective The present research investigated potential effects of mindfulness training on emotion regulation and mood of future schoolteachers in a nonrandomized pre–post design, and whether these are influenced by the yoga component of mindfulness‐based stress reduction (MBSR) and/or by homework practice. Method N = 169 university students received either mindfulness training (experimental groups), awareness activities (active control group), or no training (passive control group), in the context of university seminars. Allocation to groups was bound by the seminar chosen by participants, and in that sense was self‐selected. Mindfulness was trained in two adapted MBSR courses, one of which including yoga, and the other excluding yoga. Results Specific benefits of both mindfulness training groups were observed for emotion regulation in terms of an increase in cognitive reappraisal and a reduction in symptom‐focused rumination as well as depressive mood. No benefits of mindfulness training were observed for reductions in expressive suppression, self‐focused rumination, anxious, and negative mood or an increase in distraction and positive mood respectively. Mindfulness training with and without yoga was mostly equally effective. Outcomes were largely not moderated by practice quantity or quality, but reductions in depressive mood were mediated by gains in reappraisal and distraction. Conclusions Mindfulness training can be implemented in the context of university seminars to foster advantageous emotion regulation strategies and lower depressive mood in future schoolteachers. Discontinuing yoga within mindfulness interventions does not seem to reduce training benefits.

We report a study testing the validity of the three most commonly used indicators of lifetime exposure to print fiction, namely a self-report scale, an author recognition test (ART), and book counting, in a sample of older adults (N=306; Mage = 59.29 years, SDage = 7.01). Convergent validity of the self-report scale and book counting was assessed through correlations with the fiction sub-score of the ART; divergent validity of these two indicators was examined via correlations with the non-fiction sub-score of that ART. We also assessed criterion-related validity by testing the degree to which each of the three indicators predicted participants’ performance in a vocabulary test. The self-report scale and book counting were significantly more positively associated with the ART fiction sub-score than the ART non-fiction sub-score. Regression analyses, controlling for gender and non-fiction exposure, revealed that the ART fiction sub-score had the highest explanatory power among all indicators under investigation for predicting vocabulary test performance. The present results suggest that only ARTs may have satisfactory levels of both construct and criterion-related validity. Recommendations for the assessment of fiction exposure and future directions are discussed.

Two pre-registered studies investigated associations of lifetime exposure to fiction, applying a battery of self-report, explicit and implicit indicators. Study 1 ( N = 150 university students) tested the relationships between exposure to fiction and social and moral cognitive abilities in a lab setting, using a correlational design. Results failed to reveal evidence for enhanced social or moral cognition with increasing lifetime exposure to narrative fiction. Study 2 followed a cross-sectional design and compared 50–80 year-old fiction experts ( N = 66), non-fiction experts ( N = 53), and infrequent readers ( N = 77) regarding social cognition, general knowledge, imaginability, and creativity in an online setting. Fiction experts outperformed the remaining groups regarding creativity, but not regarding social cognition or imaginability. In addition, both fiction and non-fiction experts demonstrated higher general knowledge than infrequent readers. Taken together, the present results do not support theories postulating benefits of narrative fiction for social cognition, but suggest that reading fiction may be associated with a specific gain in creativity, and that print (fiction or non-fiction) exposure has a general enhancement effect on world knowledge.

We report an event-related brain potential (ERP) experiment that tests whether autistic adults are able to maintain and switch between counterfactual and factual worlds. Participants (N = 48) read scenarios that set up a factual or counterfactual scenario, then either maintained the counterfactual world or switched back to the factual world. When the context maintained the world, participants showed appropriate detection of the inconsistent critical word. In contrast, when participants had to switch from a counterfactual to factual world, they initially experienced interference from the counterfactual context, then favoured the factual interpretation of events. None of these effects were modulated by group, despite group-level impairments in Theory of Mind and cognitive flexibility among the autistic adults. These results demonstrate that autistic adults can appropriately use complex contextual cues to maintain and/or update mental representations of counterfactual and factual events.

We present two experiments examining the effects of reading narrative fiction (vs. narrative non-fiction vs. expository non-fiction) on social and moral cognition, using a battery of self-report, explicit and implicit indicators. Experiment 1 (N = 340) implemented a pre-registered, randomized between-groups design, and assessed multiple outcomes after a short reading assignment. Results failed to reveal any differences between the three reading conditions on either social or moral cognition. Experiment 2 employed a longitudinal design. N = 104 participants were randomly assigned to read an entire book over seven days. Outcome variables were assessed before and after the reading assignment as well as at a one-week follow-up. Results did not show any differential development between the three reading conditions over time. The present results do not support the claim that reading narrative fiction is apt to improve our general social and moral cognition.
