Two sides of the self-love coin: Self-compassion text-only posts and body positive photo-based content both positively affect body image.

Although body-positive content is associated with increased positive body image, concerns regarding the continued focus on appearance have emerged. Therefore, the purpose of this study was to examine whether self-compassion text-only content provided benefits beyond traditional photo-based body positivity content. Undergraduates (n = 283; 179 women, 104 men) were randomly assigned to view body positive photos, self-compassion text-only content, or architectural images (control condition). Participants assigned to both experimental conditions demonstrated a significant increase in measures of state body appreciation, state body satisfaction, and state self-compassion, however they did not differ significantly from each other. The self-compassion condition also differed significantly from the control condition. Trait appearance comparisons moderated the relationship between experimental condition and state body appreciation and state body satisfaction, and gender did not affect the relationship between condition and the outcome measures. Results of this study support the inclusion of body-positivity images and self-compassion text-only content in social media interventions for improving body image for men and women.

Walking in nature may improve affect but not cognition.

Beneficial effects of natural environments on affect have been consistently reported, but effects on cognition have been less consistent. We examined affect and cognitive performance in the domains of attention, working memory, executive function, and recall and recognition memory in a sample of 188 undergraduate participants who completed a walk in one of three environments: an outdoor nature environment, an outdoor urban environment, or an indoor (treadmill) environment. Supporting the hypotheses, the outdoor nature environment resulted in the greatest increase in positive affect and decrease in negative affect from pre-to post-walk. However, there were no effects of location on any cognitive measure. These results suggest that cognitive effects do not always occur in tandem with affective benefits. Possible explanations, including prior frequent exposure to nature in our participants and extremity of the natural environment, are discussed.

First do no harm: Measuring weight bias beliefs in preschool-age children.

Although the importance of investigating the development of weight bias in young children has been documented, little research has examined potential impacts of children's participation in such research. The purpose of the current study was to assess whether participation in research measuring beliefs about body size may engender changes in the development of weight beliefs in young children. Eighty children (44 boys, 36 girls), ages 3-5 (M = 3.73, SD =0.69) participated in tasks assessing weight bias beliefs and perception of their own body size at two time periods (two weeks apart). Participants' responses at Time 2 were also compared to data collected from a similar sample who completed the measures only once. Results demonstrated main effects of gender (girls reporting greater weight bias) and age (older children reporting greater weight bias)) across time points that are consistent with prior research. Importantly, there was no change in participants' responses from Time 1 to Time 2 and no significant differences between Time 2 data and data collected from participants who only completed the measures at one time period, suggesting that participation in such research may not pose undue risks to young children.

Dogs Supporting Human Health and Well-Being: A Biopsychosocial Approach.

Humans have long realized that dogs can be helpful, in a number of ways, to achieving important goals. This is evident from our earliest interactions involving the shared goal of avoiding predators and acquiring food, to our more recent inclusion of dogs in a variety of contexts including therapeutic and educational settings. This paper utilizes a longstanding theoretical framework- the biopsychosocial model- to contextualize the existing research on a broad spectrum of settings and populations in which dogs have been included as an adjunct or complementary therapy to improve some aspect of human health and well-being. A wide variety of evidence is considered within key topical areas including cognition, learning disorders, neurotypical and neurodiverse populations, mental and physical health, and disabilities. A dynamic version of the biopsychosocial model is used to organize and discuss the findings, to consider how possible mechanisms of action may impact overall human health and well-being, and to frame and guide future research questions and investigations.

Natural Is Not Always Better: The Varied Effects of a Natural Environment and Exercise on Affect and Cognition.

The Attention Restoration Theory (ART) has been widely cited to account for beneficial effects of natural environments on affect and attention. However, the effects of environment and exercise are not consistent. In a within-subjects design, participants completed affective and cognitive measures that varied in attentional demands (memory, working memory, and executive function) both before and after exercise in a natural and indoor environment. Contrary to the hypotheses, a natural environment resulted in lower positive affect and no difference in negative affect compared to an indoor environment. A natural environment resulted in the most improvement for cognitive tasks that required moderate attentional demand: Trail Making Test A and Digit Span Forwards. As predicted, exercise resulted in improved affect and improved executive function (Trail Making Test B). There were no interactions between environment and exercise. These results suggest that ART cannot fully explain the influence of environment on affect and cognition.

The Relationship of Cognitive Performance and the Theta-Alpha Power Ratio Is Age-Dependent: An EEG Study of Short Term Memory and Reasoning during Task and Resting-State in Healthy Young and Old Adults.

Objective: The Theta-Alpha ratio (TAR) is known to differ based upon age and cognitive ability, with pathological electroencephalography (EEG) patterns routinely found within neurodegenerative disorders of older adults. We hypothesized that cognitive ability would predict EEG metrics differently within healthy young and old adults, and that healthy old adults not showing age-expected EEG activity may be more likely to demonstrate cognitive deficits relative to old adults showing these expected changes. Methods: In 216 EEG blocks collected in 16 young and 20 old adults during rest (eyes open, eyes closed) and cognitive tasks (short-term memory [STM]; matrix reasoning [RM; Raven's matrices]), models assessed the contributing roles of cognitive ability, age, and task in predicting the TAR. A general linear mixed-effects regression model was used to model this relationship, including interaction effects to test whether increased cognitive ability predicted TAR differently for young and old adults at rest and during cognitive tasks. Results: The relationship between cognitive ability and the TAR across all blocks showed age-dependency, and cognitive performance at the CZ midline location predicted the TAR measure when accounting for the effect of age (p < 0.05, chi-square test of nested models). Age significantly interacted with STM performance in predicting the TAR (p < 0.05); increases in STM were associated with increased TAR in young adults, but not in old adults. RM showed similar interaction effects with aging and TAR (p < 0.10). Conclusion: EEG correlates of cognitive ability are age-dependent. Adults who did not show age-related EEG changes were more likely to exhibit cognitive deficits than those who showed age-related changes. This suggests that healthy aging should produce moderate changes in Alpha and TAR measures, and the absence of such changes signals impaired cognitive functioning.

Does stress enhance or impair memory consolidation?

Three experiments examined the hypothesis that stress-induced arousal enhances long-term memory for experiences associated with arousing events. Contrary to expectations, in each experiment exposure to a stressor (arm immersion in ice water) interfered with, rather than enhanced, long-term memory for associated material. Despite varying the stimuli (words, pictures), their emotional value (positive, negative, neutral), the time between learning and stress inductions (0 to 1 minute), and opportunities for post-learning rehearsal, each experiment produced a significant reversal of the hypothesised effect. That is, in each experiment, exposure to a stressor interfered with, rather than enhanced, long-term memory for associated material. We conclude that the relationship between stress and memory consolidation is more bounded than previously believed.
