Adult-child interaction under dyadic and polyadic conditions

The nature of adult-child interaction was examined under two conditions: dyadic (adult with one child) and polyadic (adult with four children). The subjects were staff and children in day nurseries, who were observed in a specially set-up task situation. In certain respects the interaction assumed different forms depending on group condition. The effects may be seen in stylistic differences in the adults' behaviour: thus in polyads individual children had not only less speech directed to them but also speech that tended to be more directive and prohibitive. While the total number of bids the adults received from children in polyads was considerably greater than in dyads, the increase was a selective one, referring only to requests for help and not to less urgent demands. The main strategy adopted by adults to cope with the increase in demand was by ignoring, the incidence of which was very much greater under polyadic than under dyadic conditions. Joint involvement of adult and child was also much reduced in the former setting. The implications of these findings for children reared under group care conditions are discussed, and attention is drawn to the importance of situational factors in determining caretaker responsiveness.     

Maternal and infant characteristics connected to shared pleasure in dyadic interaction

The aim of the study was to analyze which maternal factors (depressive symptoms, effect of life events, maternal sensitivity and structuring) and infant characteristics (temperament, social withdrawal symptoms, interactive behavior, genotype, gender) contribute to shared pleasure (SP) in parent–infant interaction. Participants were 113 mother–infant dyads. The mothers filled in the Edinburgh Postnatal Depression Scale, the Infant Behavior Questionnaire, and the Life Events Questionnaire. The dyads were videotaped in a free-play situation, and the videos were analyzed using the Alarm Distress Baby Scale and the Emotional Availability Scales. The infants were genotyped for four genes involved in emotion regulation. The occurrence and duration of SP (SP-MD) in mother–infant interactions were analyzed from the videotapes. Higher maternal sensitivity and depressive symptoms, better infant responsiveness, and the infant having the GG variant of the gene tryptophan hydroxylase isoform 2 (TPH2) -307 were associated with the occurrence of SP. Lower level depressive symptoms, better maternal structuring, and greater infant involvement were associated with the longer duration of SP. Those dyads where the mother and infant were best able to read each other's positive cues and to respond to them were more likely to experience mutual positive affect, as seen in SP.     

Marital interaction in dyadic and triadic contexts: continuities and discontinuities

While the systemic metaphor used in much current family research requires examination of the interrelationships among individuals, relationships, and the family as a whole, work on triadic relationships has generally been missing. This research examined the presence of second-order effects in marital interaction: changes in interactions between spouses when the husband-wife dyad became a parent-parent-child triad. Results indicated the presence of consistent context effects. Parental behavior when alone was not a good predictor of parental behavior in the presence of a child: behaviors occurred at significantly lower levels in parental dyads than in parent-parent-child triads, and correlations across the two contexts were less than consistent. Results are discussed in light of their implications for observations of families.     

The dyadic interaction of persons with violent and nonviolent histories

College students were classified as having violent or nonviolent histories on the basis of their responses to the Conflict Tactics Scale (CTS). Four groups of heterosexual pairs were then recalled for further testing: violent males paired with violent females, violent males with nonviolent females, nonviolent males with violent females, and nonviolent males with nonviolent females. These pairs were asked to role play their attempt to resolve an hypothetical conflict while being videotaped. Subsequently, their behavior was recorded into the three summary categories that emcompass the Marital Interaction Coding System. Persons with violent histories were more frequently negative than those with nonviolent histories while interacting with an individual having a similar history. This result supports the validity of the CTS by demonstrating that it is capable of predicting behavior during the verbal resolution of a conflict. However, the results suggested that the nature of the contribution to the aversiveness of the interaction may be different for males and females. Overall, these results offer some support for the notion that some individuals learn aversive behavior as a general behavioral style for controlling their environments with the probability of performing coercive behavior partially a function of other individuals.     

Infant's action skill dynamically modulates parental action demonstration in the dyadic interaction

When interacting with infants, human adults modify their behaviours in an exaggerated manner. Previous studies have demonstrated that infant‐directed modification affects the infant's behaviour. However, little is known about how infant‐directed modification is elicited during infant–parent interaction. We investigated whether and how the infant's behaviour affects the mother's action during an interaction. We recorded three‐dimensional information of cup movements while mothers demonstrated a cup‐nesting task during interaction with their infants aged 11 to 13 months. Analyses revealed that spatial characteristics of the mother's task demonstration clearly changed depending on the infant's object manipulation. In particular, the variance in the distance that the cup was moved decreased after the infant's cup nesting and increased after the infant's task‐irrelevant manipulation (e.g. cup banging). This pattern was not observed for mothers with 6‐ to 8‐month‐olds, who do not have the fine motor skill to perform the action. These results indicate that the infant's action skill dynamically affects the infant‐directed action and suggest that the mother is sensitive to the infant's potential to learn a novel action.

Kangaroo mother care and mother‐premature infant dyadic interaction

The aim of this study was to investigate the psychological impact of Kangaroo Mother Care (KMC) on mother‐infant bonding in cases of premature delivery. Examined variables were mother‐infant relationships, maternal anxiety levels, and infant interactive signals. The KMC method requires that babies be undressed and held upright between their mother's breasts for a minimum of 1 hr a day, from birth until they are discharged from hospital. The present study examined 40 premature infants and their mothers, with 21 dyads experiencing KMC and 19 receiving traditional care (TC). Maternal emotional stress was assessed with the Parent Stress Index‐Short Form questionnaire (Abidin, 1990), and mother‐newborn interactive style was assessed with the Nursing Child Assessment Feeding Scale (Barnard, 1975). Results revealed a better mother‐infant interactive style, a significant decrease in maternal emotional stress, and better infant ability to make requests and respond to parental interactive style in the KMC group.     

Initial dyadic peer interaction of attention deficit-hyperactivity disorder and normal boys

The present study assessed the frequency and patterns of play duration and verbal behavior of medicated attention deficit-hyperactivity disorder (ADHD) boys in an initial social encounter with a normal, same-age peer. Eight pairs each of previously unacquainted ADHD/normal boys and normal/normal boys were videotaped as they interacted in a free-play setting (N=32). The ADHD/normal dyads engaged in more solitary play and less associative play than the normal/normal dyads. Sequential analyses of the ADHD/normal dyads' play patterns revealed that they had problems in their progression along the play hierarchy, in sustaining associative play, and in avoiding withdrawal after rough and tumble play. In comparison to the normal/normal dyads, the ADHD/normal dyads also differed in the quality of verbal interaction as seen in their lower levels of verbal reciprocity and affective expression. Process explanations for the problems ADHD boys display in an initial social encounter and the implications of these difficulties for diminished socialization opportunities were discussed.This research was supported by a University of Richmond undergraduate research grant to the first author.

Body posture and interpersonal perception in a dyadic interaction: A Big Two analysis

Body posture influences feelings about the self, but little is known about its impact on social cognition more generally. We apply the Big Two framework (Agency/Competence, Communion/Warmth) and study how body posture influences interpersonal perception in a dyadic interaction. In three experiments, we studied dyads with different body postures (Exps. 1 and 2: expanded/restricted; Exp. 3: expanded/neutral). Dyad members worked on a joint task, and rated self and other. Findings showed that participants in an expanded posture rated the self higher and the other lower on agency, whereas those in a submissive (or neutral) posture rated the self lower and the other higher on agency. In Experiment 2, participants in a submissive posture also rated their communion lower. Results are important both for the impact of body posture on interpersonal perception and for context effects in the relationship of Agency versus Communion ratings of self and others.     

Maternal depression and dyadic interaction: the role of maternal attachment style

Maternal mental health and the contents of her representational world are important determinants of early parent–child relationship. We examined, first, the role of prenatal and postnatal depressive symptoms and maternal attachment style in predicting the quality of mother–child interaction. Second, we analysed whether the secure‐autonomous attachment style can protect the dyadic interaction from the negative effects of maternal depression. The participants were 59 mother–infant pairs examined during pregnancy (T1), 4–5 months postpartum (T2) and when the children were approximately 14 months old (T3). Maternal attachment style was assessed with a modified Adult Attachment Interview ‐procedure, depressive symptoms with Edinburgh Postnatal Depression Scale, and observed mother–child interaction with Care Index. The results show that autonomous mothers were more sensitive and responsive and their children more co‐operative than dyads with dismissing maternal attachment style. As hypothesized, mothers with the combination of both prenatal and postpartum depressive symptoms were highly unresponsive in their dyadic interaction. Further, prenatal depressive symptoms had a stronger impact on maternal unresponsiveness than postnatal symptoms. As hypothesized, mother's autonomous attachment style protected the mother–child interaction from the negative impact of maternal postnatal depressive symptoms, whereas dyads with preoccupied mothers were especially at risk for interaction problems when mothers had postpartum depressive symptoms.

Gender roles,computer attitudes,and dyadic computer interaction performance in college students

Females tend to score lower than males on measures of computer aptitude and attitudes. This study examined the potential effects of several mediating factors, sex of experimenter, sex of experimental partner, sex typing (Bem Sex Role Inventory score), and level of past experience, on a computer interaction task involving a dyad. College students, drawn from a primarily white college population, after completing paper-and-pencil measures assessing computer experience, computer attitudes, and gender roles, participated in a computer task involving drawing up to ten prescribed geometric patterns on a computer screen. Research assistants recorded the number of correctly completed patterns and videotaped participant interaction through a one-way mirror. Males reported experiencing more computer involvement than females. For males, past computer experience and masculinity were correlated with more positive computer attitude scores. For females, only past computer experience related to more positive computer attitude scores. Analyses of the computer interaction variable indicated that participants asked male research assistants significantly more questions than female research assistants. Several interaction effects were also found.A previous version of this paper was presented at the annual meeting of the Southwestern Psychological Association, New Orleans, April 1991.     

Infants' vagal regulation in the still-face paradigm is related to dyadic coordination of mother-infant interaction

The authors investigated relations between mother-infant dyadic coordination and infants' physiological responses. Mothers (N=73) and 3-month-old male and female infants were observed in the still-face paradigm, and mothers' and infants' affective states were coded at 1-s intervals. Synchrony and levels of matching between mother-infant affective states were computed, and infants' heart rate and vagal tone were measured. Infants showed increased negative affect and heart rate and decreased vagal tone during mothers' still-face, indicating physiological regulation of distress. Infants who did not suppress vagal tone during the still-face (nonsuppressors) showed less positive affect, higher reactivity and vagal suppression in normal play and reunion episodes, and lower synchrony in normal play with mothers. The results indicate that infants' physiological regulation in social interaction differs in relation to dyadic coordination of affective behaviors.     

Imposed latencies,interruptions and dyadic interaction: Physiological response and interpersonal attraction

This study explored the impact of paralinguistic phenomena on interpersonal attraction and physiological measures during dyadic interaction. Conversations between undergraduate subjects and same-sex experimenters were either synchronous or asynchronous, with half the asynchronous conversations including imposed long latencies and the remainder frequent interruptions. Results showed that imposed latencies were associated with decreased positive attributions and greater physiological arousal, but interruptions had a moderately positive effect. The findings were discussed in terms of Chapple's theory of interaction, and their implications for psychotherapy and other interviews.     

Emotional signals in nonverbal interaction: dyadic facilitation and convergence in expressions, appraisals, and feelings

We examined social facilitation and emotional convergence in amusement, sadness, and fear in dynamic interactions. Dyads of friends or strangers jointly watched emotion-eliciting films while they either could or could not communicate nonverbally. We assessed three components of each emotion (expressions, appraisals, and feelings), as well as attention to and social motives toward the co-participant. In Study 1, participants interacted through a mute videoconference. In Study 2, they sat next to each other and either were or were not separated by a partition. Results revealed that facilitation and convergence are not uniform across different emotions and emotion components. Particularly strong supporting patterns emerged for the facilitation of and convergence in smiling. When direct interaction was possible (Study 2), friends showed a general tendency for strong convergence, with the exception of fear-related appraisals. This suggests that underlying processes of emotional contagion and social appraisal are differentially relevant for different emotions.     

Problematic dyadic interaction among toddlers and their polydrug‐cocaine‐using mothers

Dyadic interactions between 84 at‐risk toddlers and their nondrug‐, polydrug‐non‐cocaine‐, or polydrug‐cocaine‐using mothers were examined during unstructured play. Coded videotaped behaviors revealed two maternal constructs (interactive competence, maladaptive engagement) and three toddler constructs (responsiveness, active positive initiation, play). Cocaine‐using mothers displayed more maladaptive engagement than did prenatal nondrug users; however, poorer interactive competence further distinguished them from polydrug‐but‐noncocaine users. Toddlers of cocaine‐using mothers displayed less responsiveness and positive initiation than non‐drug‐group peers; however, these behaviors did not reliably differ from polydrug‐non‐cocaine counterparts. Play interest remained relatively similar across groups. Results suggest that difficulties in social interaction appear to continue among cocaine‐using mothers during dyadic exchanges with their offspring in the second year; however, toddler deficits do not appear to be greater than those experienced by polydrug‐non‐cocaine counterparts.
