The triadic systems model perspective and adolescent risk taking

In this special issue, Ernst (2014) outlines the triadic systems model, which focuses on the balanced interaction among three functional neural systems: the prefrontal cortex (regulation/control), striatum (motivation/approach), and amygdala (emotion/avoidance). Asynchrony in maturation timelines, coupled with less mature connectivity across brain regions, is thought to result in unique vulnerabilities for risk taking during the adolescent age period. Yet, the research evidence linking the triadic systems model to differences in risk taking across adolescence and adulthood is equivocal, and few studies have examined how neural development is associated with real-world behavior. In this commentary, we outline research on adolescent risk taking which highlights the importance of considering trait level and situational conditions when examining associations between neural systems and behavior, as well as the need to adopt a lifespan perspective.     

Spillover to triadic and dyadic systems in families with young children

Research has evidenced support for the spillover model, which asserts that parents' marital functioning influences their parenting and coparenting behavior in dyadic (mother-child and father-child) and triadic (mother-father-child) family contexts. However, few studies have simultaneously investigated the spillover model in both parenting and coparenting systems, preventing examination of whether spillover impacts both systems equally or differentially. Further, little research has examined whether quality of the marital system influences children's behavior toward their parents, as well as their parents' behavior, in dyadic interactions. We examined the spillover model using observational measures of parent and child behavior in parent-child dyadic interactions as well as coparenting in triadic interactions. We also explored parent and child gender differences in spillover effects. Participants were families with children aged 3 to 6 years (n = 149). Findings indicated that spillover occurs to multiple family systems, but the effects varied according to whose behavior (mother, father, child) was explored. In families of boys and girls, the marital system influenced warmth in triadic interactions, as well as fathers' responsiveness and children's responsiveness to mothers in dyadic interactions. Spillover effects were largely equivalent for girls and boys, but spillover to coparenting hostility in triadic interactions was limited to families raising girls. Parent gender also moderated associations between marital functioning and parent-child interactions: Spillover was significantly stronger for fathers' responsiveness (vs. mothers' responsiveness) and child responsiveness to mothers (vs. child responsiveness to fathers).     

Quantification for Peirce's preferred system of triadic logic

Without introducing quantifiers, minimal axiomatic systems have already been constructed for Peirce's triadic logics. The present paper constructs a dual pair of axiomatic systems which can be used to introduce quantifiers into Peirce's preferred system of triadic logic. It is assumed (on the basis of textual evidence) that Peirce would prefer a system which rejects the absurd but tolerates the absolutely undecidable. The systems which are introduced are shown to be absolutely consistent, deductively complete, and minimal. These dual axiomatic systems reveal an interesting elegance, independent of their historical motivation.     

Systemic analysis of father-mother-baby interactions: The Lausanne triadic play

Taking on the study of triadic interactions necessitates a dual perspective—one focusing on the triad as a whole and the other on the organization of its parts. Our method associates the framework of systems theory with the ethological-microanalytical approach. We use it both as a clinical tool and to analyze thoroughly visible interactions in single cases, leading to the comparison of problematic and nonproblematic families in order to explore and generate hypotheses. To introduce our methodology, we first present the Lausanne triadic play exercise, which we designed for the observation of the triad as a whole while systematically varying the individual contributions. We then describe our method for analyz ing the triadic interactions on the upper body, lower body, and gaze levels. We illustrate it through the analysis of two contrasting families with 17-week-old babies which, on clinical grounds, represent key aspects of interaction found in our population.     

Play with me at my speed: describing differences in the tempo of parent-infant interactions in the Lausanne Triadic Play paradigm in two cultures

The goal of the present study was to examine the tempo of triadic play in Swedish and American families through a comparison of 20 families from each culture. When infants were approximately 3 months old, families in both cultures participated in the Lausanne Triadic Play (LTP), a paradigm that facilitates the examination of the triad as a whole and an organization of its parts. All family play sessions were coded separately in Sweden and America using coding systems that had been developed in each country. Dynamics within the triadic play were compared across cultures, and also across coding systems. Results indicated that both coding systems described a distinct difference in the tempo of play between American and Swedish Families. Overall, although there were many similarities between countries, American families were found to have a faster pace in triadic play than Swedish families. This difference in tempo is explored in the data analyses and the discussion of this article.     

Situating System and Giving Self Its Due: A Story-Based Counseling Model

This essay explores Michael P. Nichols' criticism of certain aspects of the family systems therapeutic model, especially his concern that it takes insufficient account of the self in the family system. Building on Nichols' argument, and noting the paradigm shift occurring among family therapists from systems to story thinking, the essay sets forth a story model of counseling having four primary postulates: (a) possibilities for change are inherent in every story told; (b) characters in stories are always more than their ascribed social roles; (c) systems or dyadic and triadic relationships are a property of stories; and (d) the self is both a constituent of stories and exists independently of them. The importance of autobiographical studies to mediate pastoral theology's theoretical interest in theological anthropology and the story model of pastoral counseling is noted but not explored in depth.     

The Sequential Production of Social Acts in Conversation

With reference to Mead, Peirce, speech act theory, conversation analysis, and Luhmann's phenomenological grounded version of systems theory, the paper tries to reconstruct actions as products of communication. A triadic sequence is identified as the elementary unit for the intersubjective constitution of an act. This unit combines three achievements: (a) the constitution of meaning by sequential attribution, (b) the intersubjective coordination of attributed meanings, and (c) the reproduction of rules, guiding the process of constitution and coordination of attributed meanings. Then, using the tools of systems theory and applying them to empirical results of ethnomethodology and conversation analysis, it is shown how the rule scheme is integrated in a triadic sequence, functioning on three different levels of communication. Finally, a specific form of repair after next turn is discussed, relating it to the function of preserving the structure of conversational types. The analysis of such conversational types opens a possible realm of cooperation between conversation analysis and Luhmann's version of systems theory.

The space of reflection: thirdness and triadic relationships in family therapy

This article explores ideas about threes and the triadic space of reflection. Early family therapy theory offered rich ideas about triadic relationship patterns. Contemporary practice frameworks have generated reflective therapeutic practices and an attention to reflexivity. Meanwhile, a contemporary theory constellation allied with psychoanalysis has studied the capacity for ‘thirdness’ in intersubjective relating, reflective functioning and mentalization, and the triadic space of thinking. The article reviews this psychoanalytic theory, explores symbolic thirdness alongside actual triadic relating, and maps an understanding of the space of reflection as triadic and relational. Thinking about the space of reflection as triadic and relational offers one way of orienting ourselves to reflective processes and an inclusive frame for valuing both the earlier family therapy attention to relationship patterns and the different, current contemporary family therapy practices of reflection.     

The nested neural hierarchy and the self

In spite of enormous recent interest in the neurobiology of the self, we currently have no global models of the brain that explain how its anatomical structure, connectivity, and physiological functioning create a unified self. In this article I present a triadic neurohierarchical model of the self that proposes that the self can be understood as the product of three hierarchical anatomical systems: The interoself system, the integrative self system, and the exterosensorimotor system. An analysis of these three systems and their functional features indicates that the neural hierarchy possesses features of both non-nested and nested hierarchies that are necessary for the creation of a unified consciousness and self. These functional properties also make the central nervous system a biologically unique entity unlike anything else in nature.     

Dyadic and triadic skills in preterm and full term infants: a longitudinal study in the first year

This longitudinal study examined dyadic and triadic skills in 26 preterm and 31 full term infants at 3, 6 and 9 months of age. In dyadic interaction, infants engaged with a stranger in face-to-face play interrupted by a still-face episode. In triadic interaction, infants interacted with the adult stranger as she coordinated gaze between the infant and object. Both groups were sensitive for non-contingency in both dyadic and triadic interactions. There were significant group and developmental differences for dyadic and triadic competencies. Compared to full term infants, preterms made less positive elicits during the still-face at 6 months and followed gaze less at 9 months of age. Six-month dyadic skills and 9-month triadic competencies were positively related in preterm and full term infants.     

The triadic model as applied to the treatment of conduct-disordered children: A review and critique

Conduct-disordered behaviour in children has long been recognised as an area of particular concern for counsellors, clinical and educational psychologists and other professionals, especially given its widespread incidence and poor long-term prognosis. In response to this concern, one recent development in the field has been the use of an applied social learning theory approach, utilising a triadic model of intervention. Such a model, rather than working directly with the child, firmly locates the parent or other caregiver as the agent of change. This paper reviews critically the work which has been carried out under the broad rubric of the triadic model, addressing specifcally the short- and longer-term efficacy of such interventions. In addition, certain shortcomings and limitations in existing practice are identifed. It is argued that, in order to optimise the effectiveness of interventions, this will in many instances require a consideration of and work on parental well-being and self-esteem, the role of family dynamics and the influence of the social context.     

Laterality effects in the method of triads

The method of triads for psychophysical judgments was analyzed in terms of the unidimensional unfolding model of Coombs (1964). This model predicts laterality effects on the stochastic transitivity of triples for which existing models have been unable to account. An experiment was conducted in which triadic judgments were made on circles differing in area. The results confirmed the stochastic transitivity predictions, but a quantitative formulation of the model proved unsatisfactory.     

Mother–Father–Child Triadic Interaction and Mother–Child Dyadic Interaction: Gender Differences Within and Between Contexts

Differences in mother and father behavior during a triadic interaction session, and differences in mothers’ behavior across triadic and dyadic interaction, were examined in 60 two-parent families with an 11- to 15-month-old child (30 boys, 30 girls). Results revealed that mothers were less involved, less sensitive, and more negative during triadic than during dyadic interaction. Mothers of sons displayed more emotion during triadic interaction than mothers of daughters did. Mothers were more involved with children than fathers were during triadic interaction, whereas fathers displayed more emotion than mothers did during triadic interaction. Fathers were more supportive of mothers, and mothers were more intrusive toward fathers, during triadic interaction. The results are discussed in terms of the role that context plays in gender-typed patterns of family interaction.     

Effects of a pairing contingency on behavior in a three-person programmed environment

Four groups of three subjects resided for 10 days within a continuously programmed environment. Subjects followed a behavioral program of contingently scheduled activities that determined individual and social behaviors. A triadic condition was in effect when all three subjects were required to select simultaneous access to a group area before it became available for a social episode. A dyadic condition was in effect when access to a group area was permitted to any combination of two, and only two, subjects. The effects of these two conditions on individual and social behaviors were studied in reversal designs with several successive days devoted to each condition. Results showed that durations of social activities and synchronization of individual activities were greater during triadic conditions than during dyadic conditions. Under both conditions, wake-sleep cycles departed from a typical day-night rhythm for most subjects. Instances when subjects did not respond to each others' attempts to initiate conversations using the intercom were generally more frequent during dyadic than triadic conditions. Physical distance during triadic social episodes was found to be related to sociability levels during dyadic conditions.     

Mothers' and Fathers' Parenting Quality and Toddlers' Interactive Behaviours in Dyadic and Triadic Family Contexts

Based on a family systems perspective, this research examined the role of parental gender and family play context in parent–toddler interactions and how behaviours of family members influence each other. Sixty‐seven mostly White, middle‐class families consisting of a mother, father and toddler were videotaped in three separate sessions: mother–child, father–child and both parents–child at a university laboratory setting. The results indicated that there were significant main effects of both parent gender (mother versus father) and context (dyadic versus triadic) on parents' positive and negative parenting and children's engagement and negativity toward parents. Higher levels of mutual engagement between mothers and toddlers were associated with lower levels of fathers' positive parenting and children's engagement with fathers, when moving from the dyadic to the triadic play context. However, fathers' mutual engagement with toddlers was not associated with mothers' parenting quality and child interactive behaviours with mothers. There were also interaction effects of parent gender and context on parents' negative parenting and children's engagement and negativity toward parents. This study adds unique insights to the differences and similarities of parent–child dyadic and triadic interactions during toddlerhood. Copyright © 2012 John Wiley & Sons, Ltd.     

Human agency in social cognitive theory

The present article examines the nature and function of human agency within the conceptual model of triadic reciprocal causation. In analyzing the operation of human agency in this interactional causal structure, social cognitive theory accords a central role to cognitive, vicarious, self-reflective, and self-regulatory processes. The issues addressed concern the psychological mechanisms through which personal agency is exercised, the hierarchical structure of self-regulatory systems, eschewal of the dichotomous construal of self as agent and self as object, and the properties of a nondualistic but nonreductional conception of human agency. The relation of agent causality to the fundamental issues of freedom and determinism is also analyzed.     

Parental capacities for triadic relationships during pregnancy: Early predictors of children's behavioral and representational functioning at preschool age

This study examines associations between parental capacities for triadic (mother–father–child) relationships, assessed prenatally, and the representational and behavioral functioning of their offspring at preschool age. Thirty‐eight parental couples were given an intensive psychodynamic interview during their first pregnancy to assess how they anticipated their future parenthood and their relationships as threesomes (mother–father–child). The capacity for triadic relationships (“triadic capacity”) was defined as the capacity of fathers and mothers to anticipate their family relationships without excluding either themselves or their partners from the relationship with the infant. Four years later, the representational and behavioral functioning of their children were assessed in depth using child narrative interviews and parental behavior ratings. The coherence of the children's narratives and the number of positive themes they expressed were significantly negatively correlated with the number of behavioral problems. In the longitudinal analyses, there were significant positive correlations between the parental triadic capacities and the coherence/number of positive themes in the children's narratives whereas parental triadic capacities showed a significant negative correlation with the number of the children's externalizing problems. The significance of triadic relational family processes for the development of children's representational world and behavioral functioning is discussed. ©2005 Michigan Association for Infant Mental Health.     

New methods,measures, and models for analyzing memory impairment using triadic comparisons

We study the effect of memory impairment on triadic comparisons of animal names in a large clinical data set. We define eight groups of subjects in terms of their delayed free recall performance, and present standard analyses of the triadic comparison and free recall data that provide little insight into the effect of memory impairment on semantic structure. We then develop and apply two new methods for analyzing the data, based on cognitive models and using Bayesian statistical inference. The first new method focuses on modeling changes in semantic representation, by inferring multidimensional scaling (MDS) representations for each group based on their triadic comparisons. These representations reveal a successive decrease in semantic cluster structure and increase in uncertainty with increasing impairment. We propose a measure of spatial organization as a means of quantifying the visually evident changes in semantic organization, and demonstrate its usefulness. The second new method focuses on modeling changes in memory access with impairment, inferring the extent to which each individual makes triadic comparisons consistent with a common semantic representation. Although these inferences are based on just 12 comparisons per subject, we show that they vary systematically with memory impairment group. We conclude by discussing the potential for clinical application of our new models, measures, and methods.
