EEG correlates of postural audio-biofeedback

The control of postural sway depends on the dynamic integration of multi-sensory information in the central nervous system. Augmentation of sensory information, such as during auditory biofeedback (ABF) of the trunk acceleration, has been shown to improve postural control. By means of quantitative electroencephalography (EEG), we examined the basic processes in the brain that are involved in the perception and cognition of auditory signals used for ABF. ABF and Fake ABF (FAKE) auditory stimulations were delivered to 10 healthy naive participants during quiet standing postural tasks, with eyes-open and closed. Trunk acceleration and 19-channels EEG were recorded at the same time. Advanced, state-of-the-art EEG analysis and modeling methods were employed to assess the possibly differential, functional activation, and localization of EEG spectral features (power in α, β, and γ bands) between the FAKE and the ABF conditions, for both the eyes-open and the eyes-closed tasks. Participants gained advantage by ABF in reducing their postural sway, as measured by a reduction of the root mean square of trunk acceleration during the ABF compared to the FAKE condition. Population-wise localization analysis performed on the comparison FAKE - ABF revealed: (i) a significant decrease of α power in the right inferior parietal cortex for the eyes-open task; (ii) a significant increase of γ power in left temporo-parietal areas for the eyes-closed task; (iii) a significant increase of γ power in the left temporo-occipital areas in the eyes-open task. EEG outcomes supported the idea that ABF for postural control heavily modulates (increases) the cortical activation in healthy participants. The sites showing the higher ABF-related modulation are among the known cortical areas associated with multi-sensory, perceptual integration, and sensorimotor integration, showing a differential activation between the eyes-open and eyes-closed conditions.     

The role of community context and psychological well-being for physical health: A dyadic study of military couples

Drawing from the social organizational theory of community action and change (SOAC) within a systemic biopsychosocial perspective, associations between community context (military community connections and satisfaction with military life), psychological well-being (depressive symptoms, anxiety, and self-efficacy), and physical health were examined for a sample of active duty service members and their civilian spouses (N = 236 couples) using an actor partner interdependence framework. Service members with higher levels of military community connections reported better psychological well-being. When civilian spouses were more satisfied with military life, both partners reported better psychological well-being. In turn, both spouses’ psychological well-being was related to their own reports of physical health. Statistically significant indirect effects were found between community contexts and spouses’ physical health. Enhancing community connections may be an important leverage point for supporting health and family readiness.     

Differentiation of Self and Dyadic Adjustment in Couple Relationships: A Dyadic Analysis Using the Actor‐Partner Interdependence Model

Bowen's multigenerational theory provides an account of how the internalization of experiences within the family of origin promotes development of the ability to maintain a distinct self whilst also making intimate connections with others. Differentiated people can maintain their I‐position in intimate relationships. They can remain calm in conflictual relationships, resolve relational problems effectively, and reach compromises. Fusion with others, emotional cut‐off, and emotional reactivity instead are common reactions to relational stress in undifferentiated people. Emotional reactivity is the tendency to react to stressors with irrational and intense emotional arousal. Fusion with others is an excessive emotional involvement in significant relationships, whilst emotional cut‐off is the tendency to manage relationship anxiety through physical and emotional distance. This study is based on Bowen's theory, starting from the assumption that dyadic adjustment can be affected both by a member's differentiation of self (actor effect) and by his or her partner's differentiation of self (partner effect). We used the Actor‐Partner Interdependence Model to study the relationship between differentiation of self and dyadic adjustment in a convenience sample of 137 heterosexual Italian couples (nonindependent, dyadic data). The couples completed the Differentiation of Self Inventory and the Dyadic Adjustment Scale. Men's dyadic adjustment depended only on their personal I‐position, whereas women's dyadic adjustment was affected by their personal I‐position and emotional cut‐off as well as by their partner's I‐position and emotional cut‐off. The empirical and clinical implications of the results are discussed.     

Molyneux' question redux

After more than three centuries, Molyneux's question continues to challenge our understanding of cognition and perceptual systems. Locke, the original recipient of the question, approached it as a theoretical exercise relevant to long-standing philosophical issues, such as nativism, the possibility of common sensibles, and the empiricism-rationalism debate. However, philosophers were quick to adopt the experimentalist's stance as soon as they became aware of recoveries from congenital blindness through ophtalmic surgery. Such recoveries were widely reported to support empiricist positions, suggesting that the question had found its empirical answer. Contrary to this common view, we argue that studies of patients recovering from early blindness through surgery cannot provide an answer. In fact, because of the very nature of such ophtalmological interventions it is impossible to test the question in the empirical conditions outlined by Molyneux. Thus we propose that Molyneux's question be treated as an early thought experiment of a specific kind. Although thought experiments of this kind cannot be turned into actual experimental conditions, they provide a conceptual restructuring of theories. Such restructuring in turn leads to new predictions that can then be tested by normal experiments. In accord with this interpretation, we show that Molyneux's question can be analyzed into a hierarchy of specific questions about vision in its phenomenal and sensory-motor components. Some of these questions do lead to actual experimental conditions that could be studied empirically.

Forgiveness and religious practice: a study on a sample of Italian preadolescents

Abstract

In this study we examined the gender differences in self-reported forgiving behaviours in a sample of Italian preadolescents (aged 11 to 14 years), who were either involved or not involved in religious practises. Were asked 289 Catholic, Italian preadolescent students were asked about their involvement in the religious practises. They also completed measures of forgiveness, avoidance and revenge motivations. The results showed that forgiveness was negatively correlated to avoidance and revenge, as expected, given that these constructs represent two different forms of non-forgiveness. Avoidance and revenge motivations were positively inter-correlated, highlighting how these forms of non-forgiveness are two distinct, but related pathways, leading away from forgiveness. Regarding age, younger participants reported higher degrees of forgiveness than their older counterparts. Lastly, regarding the association between involvement in one’s faith and gender as predictors of forgiving behaviours, only girls actively practising their faith emerged as significantly more forgiving than the other participants.     

The Importance of Parents' Community Connections for Adolescent Well‐being: An Examination of Military Families

Drawing from the Social Organization Theory of Action and Change (SOAC), this analysis of 223 military families, including active duty (AD) military and civilian partners, examines how parents' sense of community and community engagement (two elements of community connections) are associated with their own resilient coping, and ultimately with important outcomes capturing their adolescent offspring's individual well‐being (depression, anxiety, and self‐efficacy) and family well‐being (family functioning and parenting quality). The roles of child gender and military context were also examined. Parents with stronger community connections, including greater sense of community and community engagement, reported more resilient coping when faced with adversity. The resilient coping of mothers, in turn, was particularly significant for more positive youth outcomes, when compared to that of fathers. While gender and military context were associated with individual and family well‐being, analyses of model invariance indicated that the model fit similarly for male and female adolescents and those experiencing high and low levels of military transitions. Indirect effects were also examined. These findings illuminate malleable dimensions of both community life and family life, primarily showing that community contexts matter for multiple family members.
