We examined the extent to which fathers can be taught and encouraged to develop positive relationships with their children, especially in infancy, and the effects of this fathering intervention on infant development. A multifaceted relationally focused intervention was used to assist fathers in Vietnam to engage in responsive direct and indirect involvement with their infants and work together with the mother as part of a parenting team. Fathers and mothers from 13 communes in a rural and semiurban district were recruited to the intervention group. Intervention fathers received group and individual counseling before and after birth, an interactive print resource, community messages about fathering, and the opportunity to participate in a Fathers Club. Couples from 12 comparable communes in a noncontiguous district were recruited to the control group. Fathers and mothers completed questionnaires at the prebirth recruitment and at 1-, 4-, and 9-months postbirth. Intervention fathers demonstrated greater increase in knowledge and attitudes regarding father-infant relationships. Both fathers and mothers reported that fathers engaged in more affection, care-taking, and play in the early months of their infants' lives and fathers felt more attached to their infants right from birth. A developmental assessment at 9 months showed that intervention infants demonstrated higher levels of motor, language, and personal/social development. This study demonstrated that fathers can be taught to interact more sensitively, responsively, and effectively with their newborn infants. Their increased interaction and emotional attachment appears to lay the foundation for enhanced infant development.

Guided by their own amoebic self theory (C. T. Burris & J. K. Rempel, 2004), in 6 studies the authors explore the impact that involvement in an intimate relationship has on how a person appraises and responds to threat. They first show that people in relationship feel less constrained by their physical bodies compared with single people. In 3 subsequent studies involving physical size, blood/body donation, sexual activities, and responses to evil, they show that generalized sensitivity to bodily threat predicts self-protective reactions to specific physical threats among singles, but not among people in relationship, suggesting that intimate relationship involvement decreases the salience of the physical body. In the final pair of studies, they show that the salience of the physical body rebounds when people in relationship are primed, either subliminally or supraliminally, to think of themselves as distinct and separate from their partners. Thus, the present research shows how conceptualizing the self as 'us' rather than 'me' can transform an individual's response to the outside world, and highlights how physical cues in particular are affected by this process.

Based on Amoebic Self Theory, the authors propose that the salience of different threats to the self affects the extent to which an intimate relationship partner is pushed away (excluded) or pulled closer (included). When social threat is salient among persons in relationships, it is hypothesized that partners will attempt to defuse the resulting sense of interpersonal vulnerability: offending partners may be pushed away, whereas offenders themselves may draw closer. When spatial-symbolic threat is salient and the relationship's capacity to function as an identity marker is jeopardized, it is hypothesized that the partner--regardless of his or her role will be pulled closer to maintain the perception that the relationship is secure. Self-report responses to hypothetical scenarios and perceptions of behaviors during a role-play were generally consistent with these hypotheses, suggesting that both an intimate partner and the relationship with that partner can be incorporated into the self.

A cross-lagged panel design was used to examine the links between trust and attributional processes in a sample of 75 married couples throughout a period of 2 years. During the first phase of the study, participants completed a measure of marital trust, engaged in a laboratory, problem-solving discussion of a recurrent conflict-related issue, and then rated their partner's behavior and motives. Approximately 2 years later, 54 couples were again contacted and measures of trust were obtained. Forty of these couples also viewed a videotape of their laboratory problem-solving discussion from 2 years previously and rated their partner's behavior and motives. Results suggested a reciprocal causal pattern by which partner-enhancing attributions predict changes in trust and trust predicts changes in partner-enhancing attributions.

According to amoebic self theory, the boundary defining the self encompasses 3 levels of self-representation--bodily, social, and spatial-symbolic. Study 1 related a newly developed measure of individual differences in sensitivity to boundary threat across these 3 domains to values and disgust sensitivity. Four subsequent studies focused on spatial-symbolic threat sensitivity and related it to right-wing authoritarianism, aversive reactions to unfamiliar out-groups, and revulsion to vermin. A final experiment illustrates how a salient spatial-symbolic threat (dust mites) can elicit reactions toward out-groups that closely parallel mortality salience effects observed in research inspired by terror management theory, even though dust mites do not elicit mortality concerns. The importance of preserving the familiar in order to preserve the self is discussed.

A multifaceted, relationally focused intervention involving group and individual pre- and postnatal counseling, print resources, and community resources encouraged 390 fathers of newborn infants in Vietnam to responsively support mothers and work with them as a parenting team. Both partners completed questionnaires prebirth and 1-, 4-, and 9-months postbirth on measures of breastfeeding support, exclusive breastfeeding duration, relationship quality, and infant development. Compared to 412 comparison group couples, intervention couples evidenced greater father support, especially in terms of helping and responsiveness to the mother's needs. This support predicted longer exclusive breastfeeding duration, improved relationship quality, and higher levels of infant development at 9 months. Sensitively working together with mothers as a coordinated team enhanced couple's relationship functioning and improved children's developmental outcomes. [ABSTRACT FROM AUTHOR]

Self-expansion without regard for others' well-being may represent the dark side of an otherwise healthy motive. Guided by Amoebic Self-Theory (AST), we developed the Engulfing Self Scale (ESS) to measure acquisitive tendencies across AST's three domains of the self. Four studies revealed that bodily engulfment appeared generally benign, and that the problematic aspects of social engulfment were generally restricted to interpersonal contexts. Spatial-symbolic engulfment motivation was linked to a breadth of problematic indices such as psychopathy, Machiavellianism, narcissism, psychological entitlement, social dominance orientation, economic system justification, greed, and valuation of power. It also predicted reluctance to expose a cheating group leader when doing so would threaten one's own positive outcomes, greater justification of a looter's behavior when prompted take his or her perspective, and greater justification of self-serving reward allocations after defeating an ostensible competitor. Spatial-symbolic engulfment may be a motivational fountainhead for behaviors that negate others' well-being. [ABSTRACT FROM AUTHOR]

Theories and models are central to Human Factors/Ergonomics (HFE) sciences for producing new knowledge, pushing the boundaries of the field, and providing a basis for designing systems that can improve human performance. Despite the key role, there has been less attention to what constitutes a good theory/model and how to examine the relative worth of different theories/models. This study aims to bridge this gap by (1) proposing a set of criteria for evaluating models in HFE, (2) employing a methodological approach to utilize the proposed criteria, and (3) evaluating the existing models of trust in automation (TiA) according to the proposed criteria. The resulting work provides a reference guide for researchers to examine the existing models' performance and to make meaningful comparisons between TiA models. The results also shed light on the differences among TiA models in satisfying the criteria. While conceptual models offer valuable insights into identifying the causal factors, their limitation in operationalization poses a major challenge in terms of testability and empirical validity. On the other hand, although more readily testable and possessing higher predictive power, computational models are confined to capturing only partial causal factors and have reduced explanatory power capacity. The study concludes with recommendations that in order to advance as a scientific discipline, HFE should adopt modelling approaches that can help us understand the complexities of human performance in dynamic sociotechnical systems.
