Organizational Membership versus Informal Interaction: Contributions to Skills and Perceptions that Build Social Capital

Participation in formal organizations has been considered a marker of social capital, but informal interactions may also provide social-capital relevant benefits. The current studies (N = 252 undergraduates; 60 adult members of a service organization) assessed skills, outcomes, and social-structural perceptions that may be developed from organizational or informal participation. Results suggested that organizations serve as potential training grounds for diverse types of civic participation; individuals hone their leadership and public speaking skills within the structures provided by organized groups. On the other hand, informal interaction also contributed importantly to social capital formation by fostering negotiating skill, the sharing of opinions, and companionship, and by creating networks of mutual obligation.     

The emergence of personality: Dynamic foundations of individual variation

We conceptualize personality and individual variation from the perspective of dynamical systems. People’s thoughts, feelings, and predispositions for action are inherently dynamic, displaying constant change due to internal mechanisms and external forces, but over time the flow of thought and action converges on a narrow range of states—a fixed-point attractor—that provides cognitive, affective, and behavioral stability. An attractor for personal dynamics develops through two mechanisms: the synchronization of individuals’ internal states in social interaction, and the self-organization of thoughts and feelings with respect to a higher-order property (e.g., goal, self-concept). We present formal models of both processes and instantiate each in computer simulations. Discussion centers on the implications of interpersonal synchronization and self-organization dynamics for issues in personality psychology, including shared vs. non-shared environmental influences on personality development, the expression of personality in social interaction, personal stability vs. change, personal vs. situational causation, and the emergence of self-concept.

Meta‐CART: A tool to identify interactions between moderators in meta‐analysis

In the framework of meta‐analysis, moderator analysis is usually performed only univariately. When several study characteristics are available that may account for treatment effect, standard meta‐regression has difficulties in identifying interactions between them. To overcome this problem, meta‐CART has been proposed: an approach that applies classification and regression trees (CART) to identify interactions, and then subgroup meta‐analysis to test the significance of moderator effects. The previous version of meta‐CART has its shortcomings: when applying CART, the sample sizes of studies are not taken into account, and the effect sizes are dichotomized around the median value. Therefore, this article proposes new meta‐CART extensions, weighting study effect sizes by their accuracy, and using a regression tree to avoid dichotomization. In addition, new pruning rules are proposed. The performance of all versions of meta‐CART was evaluated via a Monte Carlo simulation study. The simulation results revealed that meta‐regression trees with random‐effects weights and a 0.5‐standard‐error pruning rule perform best. The required sample size for meta‐CART to achieve satisfactory performance depends on the number of study characteristics, the magnitude of the interactions, and the residual heterogeneity.

Full Information Maximum Likelihood Estimation for Latent Variable Interactions With Incomplete Indicators

Researchers have developed missing data handling techniques for estimating interaction effects in multiple regression. Extending to latent variable interactions, we investigated full information maximum likelihood (FIML) estimation to handle incompletely observed indicators for product indicator (PI) and latent moderated structural equations (LMS) methods. Drawing on the analytic work on missing data handling techniques in multiple regression with interaction effects, we compared the performance of FIML for PI and LMS analytically. We performed a simulation study to compare FIML for PI and LMS. We recommend using FIML for LMS when the indicators are missing completely at random (MCAR) or missing at random (MAR) and when they are normally distributed. FIML for LMS produces unbiased parameter estimates with small variances, correct Type I error rates, and high statistical power of interaction effects. We illustrated the use of these methods by analyzing the interaction effect between advanced cancer patients’ depression and change of inner peace well-being on future hopelessness levels.     

‘Her Majesty the Baby’: narcissistic states in babies and young children

This article considers narcissistic states in babies and young children with some reference to the myth of Narcissus in Ovid’s Metamorphosis. The object-seeking character of babies from the beginning of life is elaborated in connection with selected research from mother–baby interaction. This forms the backdrop to a discussion of withdrawal into illusions of self-sufficiency and denial of dependence in adverse circumstances. Two clinical cases are discussed in some depth. One boy whose superiority, self-reliance and pseudo maturity is prompted by anxieties around separation as he approaches starting school is considered within the parameters of ordinary transient narcissism. The lengthy psychotherapy of another child, who developed entrenched narcissistic defences as a response to traumatic, abusive and neglectful experiences in early life, and who needed considerable help, is described in greater detail. Some links are made with difficulties associated with the emergence from narcissistic functioning and encountering the pain of separation and loss.     

Chronic stress in the mother-infant dyad: Maternal hair cortisol,infant salivary cortisol and interactional synchrony

Stress physiology is shaped by early experience, with enduring effects on health. The relation of chronic maternal physiological stress, as indexed by hair cortisol, to infants’ stress systems and to mother-infant interaction quality has not been established. We examined maternal hair and salivary cortisol, six-month-old infants’ salivary cortisol, and mother-infant interaction in 121 mother-infant dyads. High maternal hair cortisol was related to higher infant average salivary cortisol concentration. Maternal hair cortisol and bedtime salivary cortisol were both uniquely related to infant bedtime salivary cortisol. Mothers with higher hair cortisol were more intrusive and had lower positive engagement synchrony with their infants. Maternal intrusiveness moderated the association of maternal hair cortisol and infant salivary cortisol, such that maternal hair and infant average salivary cortisol were related only when mothers were more intrusive. Maternal chronic physiological stress may upregulate infants’ developing stress systems, particularly in the context of lower mother-infant interaction quality.     

Affective facial expression in sub-clinically depressed and non-depressed mothers during contingent and non-contingent face-to-face interactions with their infants

BackgroundDepression in the postpartum period involves feelings of sadness, anxiety and irritability, and attenuated feelings of pleasure and comfort with the infant. Even mild- to- moderate symptoms of depression seem to have an impact on caregivers affective availability and contingent responsiveness. The aim of the present study was to investigate non-depressed and sub-clinically depressed mothers interest and affective expression during contingent and non-contingent face-to-face interaction with their infant.MethodsThe study utilized a double video (DV) set-up. The mother and the infant were presented with live real-time video sequences, which allowed for mutually responsive interaction between the mother and the infant (Live contingent sequences), or replay sequences where the interaction was set out of phase (Replay non-contingent sequences). The DV set-up consisted of five sequences: Live1-Replay1-Live2-Replay2-Live3. Based on their scores on the Edinburgh Postnatal Depression Scale (EPDS), the mothers were divided into a non-depressed and a sub-clinically depressed group (EPDS score ≥ 6).ResultsA three-way split-plot ANOVA showed that the sub-clinically depressed mothers displayed the same amount of positive and negative facial affect independent of the quality of the interaction with the infants. The non-depressed mothers displayed more positive facial affect during the non-contingent than the contingent interaction sequences, while there was no such effect for negative facial affect.ConclusionsThe results indicate that sub-clinically level depressive symptoms influence the mothers’ affective facial expression during early face-to-face interaction with their infants. One of the clinical implications is to consider even sub-clinical depressive symptoms as a risk factor for mother-infant relationship disturbances.
