Emotional availability and attachment representations in kibbutz infants and their mothers.

Three components of the attachment transmission model were examined in 48 kibbutz dyads from 2 kibbutz sleeping arrangements: communal and home-based. Concurrent assessments used the Strange Situation procedure (M. D. Ainsworth, M. C. Blehar, E. Waters, & S. Wall, 1978) for infants' attachment relations, the Adult Attachment Interview (C. George, N. Kaplan, & M. Main, 1985) for mothers' attachment representations, and the Emotional Availability Scales (Z. Biringen, J. L. Robinson, & R. N. Emde, 1993) for emotional availability in the dyads. Security of infants' attachment relations as well as autonomy of mothers' attachment representations were associated with higher emotional availability scores. In addition, significantly poorer emotional availability was found in dyads in which infants were insecurely attached and mothers were nonautonomous. Results also indicate that in the ecology of collective sleeping, the associations between the experience of emotional availability in the dyads and infants' and mothers' attachment may have been disrupted.     

The relationship of attraction and sex composition to performance and nonperformance experimental outcomes in dyads

An experimental comparison of same- and mixed-sex dyads was conducted to investigate the relationship of interpersonal attraction and dyad sex composition to performance and nonperformance experimental outcomes. Ninety dyads each performed one verbal and one quantitative problem-solving task. Significant differences in speed of performance were found for dyad sex composition, but not for attraction. Attraction had its strongest impact on dyadic satisfaction, a non-performance outcome of the experiment. Among the all-female dyads racial composition of the dyad was significantly related to satisfaction: interracial dyads had higher levels of satisfaction than intraracial dyads. The results fail to demonstrate a significant association between attraction and performance, but do confirm that attraction and satisfaction are related, an assumption of the social exchange framework.The author wishes to thank Carl Castore, Angela M.

Training 90° bimanual coordination at high frequency yields dependence on kinesthetic information and poor performance of dyadic unimanual coordination

Two groups of participants were trained to be proficient at performing bimanual 90° coordination either at a high (2.5 Hz) or low (0.5 Hz) frequency with both kinesthetic and visual information available. At high frequency, participants trained for twice as long to achieve performance comparable to participants training at low frequency. Participants were then paired within (low-low or high-high) or between (low-high) frequency groups to perform a visually coupled dyadic unimanual 90° coordination task, during which they were free to settle at any jointly determined frequency to synchronize their rhythmic movements. The results showed that the coordination skill was frequency-specific. For dyads with one or both members who had learned the 90° bimanual coordination at low frequency, the performance settled at a low frequency (≈0.5 Hz) with more successfully synchronized trials. For dyads with both members who had learned the 90° bimanual coordination at high frequency, they struggled with the task and performed poorly. The dyadic coordination settled at a higher frequency (≈1.5 Hz) on average, but with twice the variability in settling frequency and significantly fewer synchronized trials. The difference between the dyadic coordination and bimanual tasks was that only visual information was available to couple the movements in the former while both kinesthetic and visual information were available in the latter. Therefore, the high frequency group must have relied on kinesthetic information to perform both coordination tasks while the low frequency group was well able to use visual information for both. In the mixed training pairs, the low frequency trained member of the pair was likely responsible for the better performance. These conclusions were consistent with results of previous studies.     

Peer interactions of dysphoric adolescents

The present study sought to extend our knowledge of dysphoric adolescents' dyadic peer interactions. Thirty female dyads (ages 13–17) were videotaped interacting during both a structured and an unstructured task. Fourteen of the dyads were each comprised of a dysphoric girl and a nondysphoric girl; the remaining dyads were comprised of two nondysphoric girls. Girls were considered dysphoric if they scored 10 or higher on the Beck Depression Inventory. Dysphoric subjects evaluated their performances more negatively than nondysphoric subjects and rated their partners more negatively overall. The partners of the dysphoric girls were viewed by raters as less positive and less happy. They saw the dysphoric teens as making more critical comments and evaluated them more negatively overall. There was also a tendency for these girls to reject their dysphoric partners and to become more passive during the unstructured task. The findings indicate that dysphoric adolescent girls evoke negative reactions from peers and negatively influence their peers' behavior. These negative reactions from others may lead to further difficulties in negotiating the developmental tasks of adolescence.     

Decoding dyadic interactive nonverbal behaviour in Chinese and Australian cohorts: A novel dyadic puzzle‐solving task

The current study used a novel problem‐solving task in which the solution could only be reached via interactions between members of dyads. The study aimed to systematically examine how nonverbal interactive behaviour was related to the cultural background of the dyads, the participant's role in the dyad (viz., instructor, problem solver) and task repetition. Twenty‐one Australian dyads and 32 Chinese dyads performed the dyadic puzzle‐solving task while their interactions were video‐recorded. In each dyad, one instructor and one problem solver worked together to solve a seven‐piece puzzle. Six trials, each comprising a different puzzle, were completed. Results indicate that the Australian instructors engaged in significantly more eye gazing and displayed more hand gestures but smiled less than the Chinese instructors. The Australian problem solvers maintained longer eye gazing, displayed more hand gestures and more echoing than their Chinese counterparts. Over trials, the Chinese instructors reduced their total talking time, hand gestures, nodding behaviour and smiling during self‐talking more than the Australian instructors. Moreover, the problem solvers in the dyads from both countries significantly reduced their smiling across trials. The current study shows that nonverbal behaviours during dyadic interactions are related to one's cultural background, role in the task and task repetition.     

A randomized controlled trial of mother–infant psychoanalytic treatment: II. Predictive and moderating influences of qualitative patient factors

A randomized control trial was performed on 75 dyads in Stockholm, Sweden, with infants under 1½ years. It recruited mothers who worried about the babies, themselves as mothers, and/or the mother–baby relationship. Two groups of mother–infant dyads were compared. One received only Child Health Centre care (the “CHCC” group) while the other received mother–infant psychoanalytic treatment plus CHCC (the “MIP” group). Significant treatment effects were found on mother‐reported depression, interviewer‐rated dyadic relationship qualities and externally rated maternal sensitivity, and near‐significant effects on mother‐reported stress, all in favor of MIP. The objective of this study is to investigate the predictive and moderating influences on outcomes by qualitatively assessed maternal and infant characteristics. The qualitative factors covered maternal suitability for psychoanalysis, and “ideal types” of mother and child, respectively. Outcome measures from two interviews with a 6‐month interval were depression (Edinburgh Postnatal Depression Scale (J. Cox, J. Holden, & R. Sagovsky, 1987 ), stress (Swedish Parental Stress Questionnaire (M. Östberg, B. Hagekull, & S. Wettergren, 1997 ), distress (Swedish Symptom Checklist‐90 (SCL‐90; L.R. Derogatis, 1994 ; M. Fridell, Z. Cesarec, M. Johansson, & S. Malling Thorsen, 2002 ) and infant social and emotional functioning (Ages and Stages Questionnaire: Social–Emotional (J. Squires, D. Bricker, K. Heo, & E. Twombly, 2002 ), relationship qualities (Parent–Infant Global Assessment Scale (PIR‐GAS; ZERO TO THREE, 2005), and videotaped interactions (Emotional Availability Scales, Z. Biringen, J.L. Robinson, & R.N. Emde, 1998 ). Suitability for psychoanalysis predicted outcome only on the PIR‐GAS. Two overarching maternal ideal types were created, reflecting their attitude to the psychoanalytic process: “Participators” and “Abandoned.” The Participators benefited more from MIP than they did from CHCC on maternal interactive sensitivity. A contrasting, but nonsignificant, pattern was found among the Abandoned mothers. Two ideal types of babies emerged: those “Affected” and “Unaffected” by the disturbance, respectively. Among Affected babies, dyadic relationships and sensitivity among their mothers improved significantly more from MIP than they did from CHCC. The superior effects of MIP applied especially to Participator mothers and Affected infants. For Abandoned mothers and Unaffected infants, CHCC seemed to be of equal value.     

A Dyadic Perspective on Speech Accommodation and Social Connection: Both Partners' Rejection Sensitivity Matters

Findings from confederate paradigms predict that mimicry is an adaptive route to social connection for rejection‐sensitive individuals (Lakin, Chartrand, & Arkin, 2008). However, dyadic perspectives predict that whether mimicry leads to perceived connection depends on the rejection sensitivity (RS) of both partners in an interaction. We investigated these predictions in 50 college women who completed a dyadic cooperative task in which members were matched or mismatched in being dispositionally high or low in RS. We used a psycholinguistics paradigm to assess, through independent listeners' judgments (N = 162), how much interacting individuals accommodate phonetic aspects of their speech toward each other. Results confirmed predictions from confederate paradigms in matched RS dyads. However, mismatched dyads showed an asymmetry in levels of accommodation and perceived connection: Those high in RS accommodated more than their low‐RS partner but emerged feeling less connected. Mediational analyses indicated that low‐RS individuals' nonaccommodation in mismatched dyads helped explain their high‐RS partners' relatively low perceived connection to them. Establishing whether mimicry is an adaptive route to social connection requires analyzing mimicry as a dyadic process influenced by the needs of each dyad member.     

Dyadic interracial interactions: a meta-analysis

This meta-analysis examined over 40 years of research on interracial interactions by exploring 4 types of outcomes: explicit attitudes toward interaction partners, participants' self-reports of their own emotional state, nonverbal or observed behavior, and objective measures of performance. Data were collected from 108 samples (N = 12,463) comparing dyadic interracial and same-race interactions, predominantly featuring Black and White Americans. Effect sizes were small: Participants in same-race dyads tended to express marginally more positive attitudes about their partners (r = .07), reported feeling less negative affect (r = .10), showed more friendly nonverbal behavior (r = .09), and scored higher on performance measures (r = .07) than those in interracial dyads. Effect sizes also showed substantial heterogeneity, and further analyses indicated that intersectional, contextual, and relational factors moderated these outcomes. For example, when members of a dyad were the same sex, differences between interracial and same-race dyads in negative affect were reduced. Structured interactions led to more egalitarian performance outcomes than did free-form interactions, but the effects of interaction structure on nonverbal behavior depended on participant gender. Furthermore, benefits of intergroup contact were apparent: Differences in emotional state across dyadic racial composition disappeared in longer term interactions, and racial minorities, who often have greater experience with intergroup contact, experienced less negative affect in interracial interactions than did majority group members. Finally, there was a significant historical trend toward more egalitarian outcomes across dyadic racial composition for explicit attitudes and for nonverbal behavior; however, participants' emotional responses and performance have remained consistent.     

Male/Female Gaze in Same-Sex and Mixed-Sex Dyads Gender-Linked Differences and Mutual Influence

In this study, 108 university students (54 men and 54 women) were each videotaped in two 8-minute problem-solving dyadic interactions: (1) same-sex, and (2) mixed-sex. Trained observers coded the interactions for simultaneous, moment-to-moment gaze and talk behavior of both interactants. MANOVA results for three dyad types (male/male, female/female, and male/female) measured on 10 dyad gaze/talk variables showed that F/F dyads exhibited more mutual gaze/mutual talk and mutual gaze/mutual silence than either M/M or M/F dyads. F/F dyads exhibited less one gazes/same talks and mutual avert/one talks than either M/M or M/F dyads. No differences were found between M/M and M/F dyads on any variable. Analyses of individual change scores from same-sex to mixed-sex dyads indicated that the women in the M/F dyads converged to the male behavior in that dyad condition, whereas the men remained unchanged. The results are discussed in terms of speech accommodation theory.     

Dyadic synchrony among young Latina mothers and their toddlers: The role of maternal and child behavior

Synchronous interactions are an important indicator of parent-child relationship quality with positive implications for child development. Latina adolescent mothers face several demographic challenges that place them at risk for less synchronous interactions. To identify factors that may facilitate more optimal parent-child relationships in this population, our study examined maternal sensitivity and children’s behavioral styles as joint predictors of dyadic synchrony among young Latina mothers and their toddlers. Mother-toddler dyads (N = 170) were observed interacting across different tasks, and toddlers’ behavior was observed during the administration of a developmental test. Results of multivariate regressions revealed additive effects of maternal sensitivity and child behavioral styles (i.e., dysregulation and positive attentional control). Maternal sensitivity related to higher dyadic synchrony for the entire sample. Positive attentional control was related to higher dyadic synchrony for mother-daughter dyads only. Although no gender differences in dyadic synchrony or the behavior style variables emerged, the relative contribution of maternal and child factors differed by child gender, suggesting that mothers may have responded differently to similar behavior and affect displayed by boys and girls. The findings provide insights regarding factors that contribute to dyadic synchrony in this understudied population and emphasize the need to consider child gender when studying parent-child interactions in young Latina families.     

A Sequential Analysis of Depressive Behaviors Within Adolescent Peer Interactions

This study examined depressive and positive patterns of interactions among clinical and nonclinical adolescent peers within an interpersonal context. Ten clinical dyads with a depressed partner and 10 nonclinical dyads engaged in 16-min audiotaped conversations under positive and negative task instructions discussing positive and negative experiences. Conversations were unitized and coded according to depressive, aggressive, positive, and neutral behaviors. The clinical dyad-group demonstrated over two times more depressive behaviors than did the nonclinical dyad-group. Both dyad-groups exhibited increased depressive interactions during negative task instructions and increased positive interaction during positive task instructions. The loglinear approach to sequential analysis demonstrated significant overall bidirectional influence in the adolescents' dyadic interaction. Specifically, we found that the depressed adolescents' depressive behaviors decreased the likelihood of partners' aggressive behaviors, and increased the likelihood of partners' positive behaviors. Clinical and nonclinical dyad-groups showed reliable patterns of positive interaction sequences. Results demonstrate that depressive and positive behaviors are functional in adolescent dyadic interaction.     

Shared Affect and Dyadic Synchrony Among Secure and Insecure Parent–Toddler Dyads

The present investigation explored the role of shared affect in parent–child dyadic synchrony during toddlerhood and examined if patterns of dyadic synchrony and shared affect differ for secure and insecure parent–child dyads. Data were collected from 128 families with toddler age children (67 girls and 61 boys) during a laboratory assessment. Mother–toddler and father–toddler interactions were coded for shared positive and negative affect, as well as dyadic synchrony. Attachment status was assessed using the Strange Situation. Data revealed that securely attached parent–toddler dyads spent more time in synchronous interaction, and less time in asynchronous interaction, than insecurely attached parent–toddler dyads. Parent–toddler synchronous interaction among both securely and insecurely attached dyads was characterized by shared positive affect. Among insecure dyads, shared negative affect was more predominate in asynchronous than in synchronous interaction. The role of individual differences in the manifestation of synchronous interaction among securely and insecurely attached parent–toddler dyads is discussed.

The increased construct validity and clinical utility of assessing relationship quality using separate positive and negative dimensions

The Positive and Negative Quality in Marriage Scale (F. D. Fincham & K. J. Linfield, 1997) is a self-report measure that separately assesses positive and negative dimensions of relationship quality. Fincham and Linfield found that ratings of positive and negative marital quality accounted for unique variance in maladaptive attributions and self-reports of dyadic behavior beyond that accounted for by the Marital Adjustment Test (H. J. Locke & K. M. Wallace, 1959), a widely used measure of marital quality that combines these dimensions. The current study expanded on these findings using a different measure of relationship quality and observed dyadic behavior with a sample of engaged couples (N=43). The results indicate that a two-dimensional approach to measuring self-evaluations of relationship quality is more informative than a one-dimensional approach during the engagement period.     

Interaction between mother and pre-term infant at 34 weeks post-conceptional age

The impact of premature birth and perinatal medical status on early mother–infant interaction was assessed in 75 dyads with pre-term infants divided into three groups. Infants' gestational age at birth and need for neonatal intensive care intervention differentiated the groups: group 1, 23–31 weeks with intensive care; group 2, 32–35 weeks with intensive care; group 3, 32–35 weeks with no intensive care. The methodological approach was based on observations of the dyads performed when the infant reached a post. conceptional age of 34 weeks (4 weeks before estimated due date of delivery). The observations were conducted in the neonatal nursery during cleaning, face-to-face and feeding interactions. Significant group differences were found in infant distress, maternal sensitivity to the infant and dyadic behaviours of positive interaction. Group 1 dyads showed higher scores or more desirable performance than dyads of group 3. Group 2 dyads usually achieved intermediate scores and performed better than dyads of group 3, especially during the feeding situation. We suggest that, in addition to a possible emergence of maternal compensatory mechanisms in the higher-risk groups, the amount of dyadic experience after birth affects the quality of mother–infant interaction at this early stage.     

Explaining teacher-student interactions in early childhood: An interpersonal theoretical approach

The present study used an interpersonal theoretical perspective to examine the interactions between Dutch teachers and kindergartners. Interpersonal theory provides explanations for dyadic interaction behaviors by stating that complementary behaviors (dissimilar in terms of control, and similar in terms of affiliation) elicit and sustain each other. We observed 69 kindergarten children (M_age = 5.79 years) and their 37 regular teachers during a dyadic interaction task. Every 5 s, independent observers rated teachers' and children's behaviors along the interpersonal dimensions of control and affiliation. Teachers reported on children's shyness and the quality of the teacher-child relationship. Multilevel modeling provided correlational evidence for complementarity within and between dyads. Cross-lagged analyses revealed that teachers showed complementarity for control and that children showed complementarity for affiliation. Children also reacted complementarily with respect to control but only if they were shy or shared positive relationships with their teachers. Implications for theory and practice are discussed.     

Stable same‐sex friendships with higher achieving partners promote mathematical reasoning in lower achieving primary school children

This study was designed to investigate friend influence over mathematical reasoning in a sample of 374 children in 187 same‐sex friend dyads (184 girls in 92 friendships; 190 boys in 95 friendships). Participants completed surveys that measured mathematical reasoning in the 3rd grade (approximately 9 years old) and 1 year later in the 4th grade (approximately 10 years old). Analyses designed for dyadic data (i.e., longitudinal actor‐partner interdependence model) indicated that higher achieving friends influenced the mathematical reasoning of lower achieving friends, but not the reverse. Specifically, greater initial levels of mathematical reasoning among higher achieving partners in the 3rd grade predicted greater increases in mathematical reasoning from 3rd grade to 4th grade among lower achieving partners. These effects held after controlling for peer acceptance and rejection, task avoidance, interest in mathematics, maternal support for homework, parental education, length of the friendship, and friendship group norms on mathematical reasoning.     

Computer-mediated communication: task performance and satisfaction

The author assessed satisfaction and performance on 3 tasks (idea generation, intellective, judgment) among 75 dyads (N = 150) working through 1 of 3 modes of communication (instant messaging, videoconferencing, face to face). The author based predictions on the Media Naturalness Theory (N. Kock, 2001, 2002) and on findings from past researchers (e.g., D. M. DeRosa, C. Smith, & D. A. Hantula, in press) of the interaction between tasks and media. The present author did not identify task performance differences, although satisfaction with the medium was lower among those dyads communicating through an instant-messaging system than among those interacting face to face or through videoconferencing. The findings support the Media Naturalness Theory. The author discussed them in relation to the participants' frequent use of instant messaging and their familiarity with new communication media.     

Reflective family play: A model for whole family intervention in the infant and preschool clinical population

This article proposes a new treatment model, Reflective Family Play, for clinical intervention in two‐parent families of children aged 0 to 5 years. It is play‐based and grounded in the evidence‐based treatment approach of Watch Wait and Wonder (WWW) as well as the assessment tool known as the Lausanne Family Play paradigm (LFP). WWW is a dyadic treatment for caregivers and their infants or preschoolers that has been shown to shift attachment in the very young (N.J. Cohen, E. Muir, & M. Lojkasek, 1999; N.J. Cohen, M. Lojkasek, E. Muir, R. Muir & C.J. Parker, 2002). The LFP is a more recent adaptation of the Lausanne Trilogue Play paradigm (LTP; E. Fivaz‐Depeursinge & A. Corboz‐Warnery, 1999). Together, the LTP/LFP have now been used for over 2 decades as reliable measures of the family alliance and interactions in two‐parent households. By combining concepts from WWW and the LTP/LFP, a novel approach is presented for treatment in two‐caregiver households. Clinical excerpts are used to illustrate.
