Exploring the mediating role of integrative self-knowledge in the relationship between mindfulness and well-being in the context of a mindfulness-based stress reduction program

Mindfulness-based stress reduction (MBSR) is an effective program for improving well-being. A growing body of studies is exploring the mechanisms mediating its beneficial effects. Integrative self-knowledge (ISK) is the construct of focus in this study. The primary goal of the current study was to investigate the mediating role of ISK in the relationship between improved mindful observing (MO), non-judging inner experience (NJ), and well-being following an MBSR program with an Iranian sample. Participants (n = 118) enrolled in MBSR and completed depression, anxiety, stress (DASS), Bartone Symptoms Checklist (BSC), Five-Facet Mindfulness Questionnaire, and ISK scale before and after the program. Results showed significant reductions in BSC, DASS, and improvements in MO, NJ, and ISK at the end of the program. Mediation analyses revealed that changes in ISK significantly mediated the relationship between changes in MO and NJ and symptoms (MO indirect effect on DASS: β = 0.11, confidence interval [CI] [0.003, 0.29]; NJ indirect effect on DASS: β = 0.12, CI [−0.16, 0.45]; MO indirect effect on BSC: β = 0.08, CI [0.001, 0.27]; NJ indirect effect on BSC: β = 0.09, CI [0.01, 0.22]). Improvements in MO and NJ may provide a pathway to cultivating ISK in MBSR, which may lead to enhanced well-being.     

A Structural Model of Racial Discrimination, Acculturative Stress, and Cultural Resources Among Arab American Adolescents

Despite evidence towards the risk for discrimination and acculturative stress that Arab American adolescents may face, the link between socio-cultural adversities and psychological well-being in this population has not been established. This study examined the role of socio-cultural adversities (discrimination and acculturative stress) and cultural resources (ethnic identity, religious support and religious coping) in terms of their direct impact on psychological distress. Using structural equation modeling, the proposed model was tested with 240 Arab American adolescents. The results indicated a strong positive relationship between socio-cultural adversities and psychological distress. Furthermore, this study supported a promotive model of cultural resources, where a negative association between cultural resources and psychological distress was found. Understanding the manner in which socio-cultural adversities and resources are linked to psychological distress can inform the development of culturally appropriate interventions that can effectively mitigate mental health concerns for understudied and vulnerable populations.     

Age differences in the neural response to emotional distraction during working memory encoding

Age-related declines in attention and working memory (WM) are well documented and may be worsened by the occurrence of distracting information. Emotionally valenced stimuli may have particularly strong distracting effects on cognition. We investigated age-related differences in emotional distraction using task-fMRI. WM performance in older adults was lower for emotional compared with neutral distractors, suggesting a disproportional impairment elicited by emotional task-irrelevant information. Critically, older adults were particularly distracted by task-irrelevant positive information, whereas the opposite pattern was found for younger adults. Age groups differed markedly in the brain response to emotional distractors; younger adults activated posterior cortical regions and the striatum, and older adults activated frontal regions. Also, an age by valence interaction was found for IFG and ACC, suggesting differential modulation of attention to task-relevant emotional information. These results provide new insights into age-related changes in emotional processing and the ability to resolve interference from emotional distraction.     

Dietary planning,self-efficacy,and outcome expectancies play a role in an online intervention on fruit and vegetable consumption

Objective: An online intervention to improve fruit and vegetable (FV) intake examines the role of planning, outcome expectancies, self-efficacy and gender. Women are not only expected to eat more FV than men, but they are also expected to be more responsive to nutritional advice and benefit more from treatment.

Method: A two-arm digital intervention with 269 men and 395 women (M_age = 41.2, SD_age = 11.45; range: 19–66 years) was conducted in Italy, Spain and Greece, followed up at three and six months, comparing a static with a dynamic, feedback-intensive platform.

Results: Linear mixed models yielded an increase in FV consumption in both the dynamic and the static intervention arms. In men, outcome expectancies were positively related to follow-up FV intake. Dietary planning interacted with self-efficacy on behavioural outcomes.

Conclusion: FV intake increased overall, and being a woman and involvement in planning facilitated behaviour change. Women seemed to be more engaged in the dynamic platform resulting in a higher amount of planning. Initial motivation, as indicated by outcome expectancies, seemed to be beneficial for men. Self-efficacious individuals benefitted from their engagement in planning, but self-efficacy did not compensate for failing to plan.     

Towards a better understanding of the relationship between executive control and theory of mind: an intra‐cultural comparison of three diverse samples

Previous research has consistently indicated that theory of mind (ToM) is associated with executive control in the preschool years. However, interpretation of this literature is limited by the fact that most studies have focused exclusively on urbanized Western cultural samples. Consequently, it is not clear whether the association between ToM and executive control reflects the specific features of this particular cohort or instead reflects a universal pattern. The present study provides the first empirical assessment of these two constructs in three diverse groups of Iranian children. Participants were 142 preschoolers (4–5 years old) from high–socioeconomic status (SES) urban (n = 33), low–SES urban (n = 37) and rural villages (n = 77). The results show that there is a robust association between ToM and executive control in all three groups, and that executive control contributes significant unique variance to ToM understanding, even after controlling for a range of variables that have been proposed as potential confounders of this relationship. However, although the three groups were equated in ToM, significant differences in executive control were evident. Moreover, cluster analysis identified three distinct clusters that were relatively homogeneous with respect to executive control and SES. One of these clusters was characterized by both low SES and low executive functioning, and showed little evidence of ToM understanding. Taken together, these findings provide possibly the clearest evidence to date that the association between ToM and executive control is not dependent on children's previous experiences on the tasks, or their family and cultural background.

Longitudinal Analysis of Associations between 3-D Mental Rotation and Mathematics Reasoning Skills during Middle School: Across and within Genders

ABSTRACT

The development of math reasoning and 3-d mental rotation skills are intertwined. However, it is currently not understood how these cognitive processes develop and interact longitudinally at the within-person level – either within or across genders. In this study, 553 students (52% girls) were assessed from fifth to seventh grades on 3-d mental rotation spatial skills (assessed each fall) and numerical and algebraic math reasoning skills (assessed each spring). Boys outperformed girls on mental rotation tests across all three grades, and on fifth and seventh grade math reasoning tests. Consistent with the literature on between-person comparisons, there was a positive correlation between mental rotation and math reasoning skills in the full sample and for both genders. A random intercept cross-lagged panel model was used to control for these confounding group-level differences in order to isolate within-person associations between earlier and later performance. Initially in fifth grade, math reasoning predicted subsequent sixth grade mental rotation skills. By seventh grade, more advanced mental rotation skills were associated with subsequent math reasoning skills while math reasoning skills were no longer predictive of mental rotation skills. An examination of gender differences revealed that this pattern was driven by boys while girls experienced less within-person change. These findings suggest that boys may initially rely in part on their math reasoning skills to solve 3-d mental rotation tasks. However, as their 3-d mental rotation skills mature, they begin to primarily depend upon these developing spatial skills to solve math reasoning problems rather than the reverse.     

The Impact of PREP Training on Marital Conflicts Reduction: A Randomized Controlled Trial With Iranian Distressed Couples

The purpose of this study was to examine the efficacy of the Prevention and Relationship Education Program (PREP) training on marital conflict and marital satisfaction among a sample of distressed couples in Iran. The research procedure was experimental with a pretest, posttest, and follow-up design, including a control group. The sample included 76 volunteer couples among a sample of distressed couples who were randomly selected and assigned to the experimental or control group. They completed demographic questions, the Marital Conflicts questionnaire, and a revised Marital Satisfaction Inventory in pretest, posttest and at the 1-year follow-up. Results showed that PREP training effectively led to decreased marital conflict and improvement of marital satisfaction of couples at posttest and at the 1-year follow-up. The result of covariance analysis showed significant differences between the experimental and the control groups' marital conflict and marital satisfaction at posttest and at the 1-year follow-up.     

Too hot to help! Exploring the impact of ambient temperature on helping

Building on the conservation of resources model, we conducted three studies to explore the link between ambient temperature and individual prosocial behavior. In study 1, analyzing the two‐wave field data from a chain of retail stores in Eastern Europe, we find that, in hot, as opposed to normal temperatures, employees are less likely to act in a prosocial manner. In study 2, we replicate and extend these findings in a randomized controlled experiment by identifying mechanisms underlying the relationship between hot ambient temperature and helping behavior. Specifically, we find that heat increases fatigue that leads to reduction in positive affect and subsequently reduces individual helping. Finally, in study 3, we replicate these findings in a field experiment. Taken together, our study helps to explain how and through what mechanisms ambient temperature influences individual helping. The theoretical and practical implications of our findings are discussed.     

Reflexive Social Orienting in Parents of Children with Autism Spectrum Disorders: Evidence from Gaze Cueing Paradigm

Twin and family studies have shown that Autism Spectrum Disorders (ASD) have a strong genetic basis and are highly heritable. First degree relatives of individuals with ASD often show mild expressions of autistic traits attributed to Broad Autism Phenotype (BAP). While numerous studies investigated different aspects of BAP, less research has been done on gaze orienting especially in parents. In the present investigation, 43 parents of children with ASD and 29 parents of typically developed children completed a modified version of gaze cueing paradigm. Results demonstrated that the control group used the eye gaze in a way that their RT was affected by congruent versus incongruent cues, while this effect was not observed in parents of individuals with ASD. Findings of the current study provide further evidence on gaze orienting deficits in parents of children with ASD, which might relate to their mild difficulties in mind-reading abilities and a common cognitive phenotype with their affected children.
