This study investigated changes of interoceptive awareness and cardiac autonomic activity induced by short-term food deprivation and its relationship to hunger and affective experience. 20 healthy women were exposed to 24 h of food deprivation in a controlled setting. Interoceptive awareness was assessed by using a heartbeat tracking task. Felt hunger, cardiac autonomic activity, mood and subjective appraisal of interoceptive sensations were assessed before and after fasting. Results show that short-term fasting intensifies interoceptive awareness, not restricted to food cues, via changes of autonomic cardiac and/or cardiodynamic activity. The increase of interoceptive awareness was positively related to felt hunger. Additionally, the results demonstrate the role of cardiac vagal activity as a potential index of emotion related self-regulation, for hunger, mood and the affective appraisal of interoceptive signals during acute fasting.

In a within-subjects design (two points of measurement, exactly seven days apart), participants' self-control strength was experimentally manipulated (depletion: yes vs. no; order counterbalanced) via the Stroop test before the participants performed a cycling task. In line with our hypothesis, hierarchical linear modelling (HLM) revealed that participants consistently performed worse over a period of 18 minutes when they were ego depleted. In addition, HLM analysis revealed that depleted participants invested less effort in the cycling task, as indicated by their lower heart rate. This effect escalated over time, as indicated by a time x condition interaction. These results indicate that self-control strength is necessary to obtain an optimal level of performance in endurance tasks requiring high levels of persistence. Practical implications are discussed.

Poor self-regulation is associated with a higher body mass index (BMI) and is a risk factor for the development of obesity. Intuitive eating, an adaptive eating style characterized by eating in response to internal cues of hunger and satiety, is associated with a lower BMI. Using cross-sectional data, this study examined whether intuitive eating mediates the relationship between self-regulation and BMI in a community sample of adults. Participants (N = 530) completed the Self-Regulation Scale, the Intuitive Eating Scale-2 with its facets Unconditional Permission to Eat (UPE), Eating for Physical Rather Than Emotional Reasons (EPR), Reliance on Hunger and Satiety Cues (RHSC) and Body-Food Choice Congruence (B-FCC). They also self-reported their height and weight. Using percentile bootstrap resampling procedures, the simple mediation analysis showed an indirect relationship between self-regulation and BMI through intuitive eating. The multiple mediation analysis revealed that EPR and B-FCC, but not UPE and RHSC, mediated the relationship between self-regulation and BMI. Intuitive eating seems to play an important intermediating role in the relationship between self-regulation and BMI. Regarding weight management interventions, it could be useful to promote intuitive eating, especially for individuals with low self-regulation. Prospective studies are needed to explore the causal and temporal relationships among self-regulation, intuitive eating and BMI.

A1 - Lensing, Johanna Nele A1 - Fay, Doris T1 - Personal initiative BT - Developmental predictors and positive outcomes from childhood to early adolescence JF - Journal of Applied Developmental Psychology N2 - Although the effects of personal initiative (PI) on adults' performance and other favorable outcomes are well documented, research has only recently begun to study PI in childhood. This study aimed at examining the development of PI, its predictors, and its developmental effects from childhood to early adolescence. A total of 1,593 German children participated in a longitudinal study starting at Grades 2 to 4, with a second measurement wave two years later. Latent change score analyses revealed that 1) children differed significantly in their change scores of PI, that 2) executive functions and positive parenting predicted change scores in PI, and that 3) high initial levels and change scores in PI reduced the development of internalizing and externalizing problems and supported the development of prosocial behavior and academic competencies. These findings endorse the plasticity of PI and shed light on the active part of children in promoting their own development.
