Differences in object sharing between infants at risk for autism and typically developing infants from 9 to 15 months of age

Object sharing abilities of infants at risk for autism (AR infants) and typically developing (TD) infants were compared from 9 to 15 months of age. Specifically, we examined the effects of infants’ locomotor abilities on their object sharing skills. 16 TD infants and 16 AR infants were observed during an “object sharing” paradigm at crawling and walking ages. Overall, AR walking infants demonstrated lower rates of object sharing with caregivers compared to TD walking infants. Specifically, AR walking infants had lower rates of giving and approaches toward caregivers compared to TD walking infants. AR walking infants also had lower step rates toward task-appropriate targets, i.e. caregivers and objects compared to TD walking infants. No group differences in object sharing were observed at crawling ages. Object sharing could be a valuable context for early identification of delays in infants at risk for developing Autism spectrum disorder.     

Differences in caregiver behaviors of infants at-risk for autism and typically developing infants from 9 to 15 months of age

During an object sharing paradigm, we compared infant-caregiver interactions between two groups: i) infants at high-risk (HR) for being diagnosed with Autism Spectrum Disorder (ASD) and ii) low-risk (LR) infants, observed at 9, 12, and 15 months of age. 16 HR infants (14 infants with an older sibling diagnosed with ASD and 2 preterm infants that received a diagnosis of ASD at 2 years) and 16 LR infants (typically developing infants without older siblings diagnosed with ASD) were included in the study. At each visit, infants played with objects in the presence of their caregivers as crawlers or walkers. Previously, we found that HR infants are less likely to share their object play with caregivers at walker ages. The present study found that caregivers of HR infants used greater directive bids including being more proximal to infants and using greater verbal and non-verbal bids to sustain their infant’s attention and to ensure their compliance during the task compared to caregivers of LR infants. Our study emphasizes the bidirectional and dynamic nature of infant-caregiver interactions. Our findings have implications for caregiver training programs that teach parents appropriate strategies to promote early social communication skills in at-risk infants.     

Content words in Hebrew child-directed speech

The goal of the study was to examine whether the ‘noun-bias’ phenomenon, which exists in the lexicon of Hebrew-speaking children, also exists in Hebrew child-directed speech (CDS) as well as in Hebrew adult-directed speech (ADS). In addition, we aimed to describe the use of the different classes of content words in the speech of Hebrew-speaking parents to their children at different ages compared to the speech of parents to adults (ADS). Thirty infants (age range 8:5–33 months) were divided into three stages according to age: pre-lexical, single-word, and early grammar. The ADS corpus included 18 Hebrew-speaking parents of children at the same three stages of language development as in the CDS corpus. The CDS corpus was collected from parent–child dyads during naturalistic activities at home: mealtime, bathing, and play. The ADS corpus was collected from parent–experimenter interactions including the parent watching a video and then being interviewed by the experimenter. 200 utterances of each sample were transcribed, coded for types and tokens and analyzed quantitatively and qualitatively. Results show that in CDS, when speaking to infants of all ages, parents’ use of types and tokens of verbs and nouns was similar and significantly higher than their use of adjectives or adverbs. In ADS, however, verbs were the main lexical category used by Hebrew-speaking parents in both types and tokens. It seems that both the properties of the input language (e.g. the pro-drop parameter) and the interactional styles of the caregivers are important factors that may influence the high presence of verbs in Hebrew-speaking parents’ ADS and CDS. The negative correlation between the widespread use of verbs in the speech of parents to their infants and the ‘noun-bias’ phenomenon in the Hebrew-child lexicon will be discussed in detail.     

Mother-infant interactions in western Lowland Gorillas (Gorilla gorilla gorilla): spatial relationships,communication, and opportunities for social learning

This study investigated mother-infant interactions in lowland gorillas (Gorilla gorilla gorilla) with particular focus on the relative role of mothers and infants in creating situations that are potentially conducive to infant social learning. Eleven gorilla mother-infant dyads were focally observed in weekly 1-hr sessions for 12 months. Spatial relationships were affected by age as well as by ambient temperature. Although the youngest infant was encouraged by its mother to walk and climb, mothers showed little or no encouragement in other contexts. In contrast, infants were quite interested in their mothers' activities, on some occasions repeated their mother's behavior, and actively encouraged their mothers to share food, play, or follow them. These findings suggest that gorilla infants are more active than their mothers in creating situations that are potentially conducive to the acquisition of knowledge or skills.     

Verbal and Nonverbal Interactions of Four- and Five-Year-Old Friends in Potential Conflict Situations

Dyads of 4- and 5-year-old friends and nonfriends attending preschools in central Italy were identified by friendship nominations. The 217 dyads of friends and non-friends participated in 2 closed-field tasks designed to simulate real-life situations of potential conflict. In the 4-year-old cohort, there were no significant differences in the behavior of the partners in either of the situations. However, at age 5 years, friends respected the rules of a fast-paced competitive game significantly more than did nonfriends. In discussing how to share a single object (a chocolate egg with a toy inside), 5-year-old friends were more likely to reach agreement than were nonfriends. The results suggest important developmental changes in the processes of negotiation and sharing within the preschool years.

Learning blossoms: Caregiver-infant interactions in an outdoor garden setting

Plants provide unique opportunities for learning by engaging all human senses. Recent laboratory studies have shown that infants use a combination of behavioural avoidance and social learning strategies to safely learn about plant properties from adults. Here we investigate how infants and their caregivers interact with plants in an outdoor garden as a first step towards examining the operation of these social learning processes in naturalistic settings. We focus on two specific aspects of spontaneous infant-caregiver interactions with plants: olfactory and touch behaviours. Additionally, we look at whether infants' and caregivers’ prior knowledge of the plants in our study influences infants’ behaviour. Our results showed a multifaceted connection between infants’ and caregivers' previous experience with the plants and their olfactory and touch behaviours. First, infants tended to touch and smell the plants after their caregivers did, and this appeared to be independent of whether infants had seen the plant before. Second, infants systematically engaged in some of the same types of olfactory and touch behaviours their caregiver displayed towards plants. Finally, infants whose caregivers were given more information about the plants in the study showed fewer touch behaviours, but no difference in olfactory behaviours. These findings bolster the previous laboratory studies of plant learning early in life, highlighting the importance of olfactory behaviours, and underscoring the benefits of using ecological observations to explore unique aspects of human development.     

Inter- and intra-cultural variation in learning-through-participation among Hadza and BaYaka forager children and adolescents from Tanzania and the Republic of Congo

We examined cross-cultural variation in children’s learning-through-participation in economic work in two forager societies; the Hadza of Tanzania and the BaYaka of the Republic of Congo. We used observational data from 46 Hadza (41% female) and 65 BaYaka (48% female) children and adolescents between the ages of 3 and 18; interview data from 73 Hadza (49% female) and 52 BaYaka (56% female) adults; and ethnographic observations from both populations. Results showed that by providing tools, assigning chores, and foraging with children, Hadza and BaYaka adults provided opportunities for autonomous learning through facilitating participation. Furthermore, although both Hadza and BaYaka children foraged alongside adults when they could be of help, Hadza children were more likely than BaYaka children to forage independently, and BaYaka children were more likely than Hadza children to participate in domestic tasks. We argue that these strategies provided children with opportunities to learn while contributing economically.

Nous avons examiné les variations interculturelles dans l’apprentissage des enfants dans le contexte de leur participation à des travaux économiques dans deux sociétés de chasseurs-cueilleurs; les Hadza de Tanzanie et les BaYaka du Congo. Nous avons utilisé les données d’observation de 46 enfants et adolescents Hadza (41% femmes) et 65 BaYaka (48% femmes) âgés de 3 à 18 ans, celles d’interviews de 73 adultes Hadza (49% femmes) et de 52 adultes BaYaka (56% femmes), ainsi que des observations ethnographiques sur ces deux groupes. Les résultats montrent qu’en leur fournissant des outils, en leur assignant des tâches et en chassant et en cueillant avec les enfants, les adultes Hadza et BaYaka leur offrent des possibilités d’apprentissage autonome tout en facilitant leur participation. En outre, alors que les enfants Hadza et BaYaka chassent et cueillent aux côtés des adultes quand ils peuvent, les enfants Hadza sont plus susceptibles que les enfants BaYaka de recourir à la chasse et à la cueillette. Ces derniers sont aussi plus susceptibles que les enfants Hadza de participer aux tâches domestiques. Nous en concluons que ces stratégies fournissent aux enfants des opportunités d’apprentissage tout en contribuant, parallèlement, aux ressources économiques de leur groupe.     

Lover and learner: Exploring relational schema change following relationship dissolution

Romantic relationships are known to be very influential, but less is known about how these relationships, and particularly the breakup of these relationships, may affect individuals’ relational schemas, or their expectations for relationships. Undergraduate students reported on how their views of themselves, romantic partners, and relationships changed after breaking up with a past partner. Results suggest that relational schemas change following relationship dissolution and that there are both positive and negative aspects to this change. There was also some evidence that aspects of the past relationship predicted change and the valence of change, and that change and the valence of change were related to aspects of current relationship quality. These results are an important first step in understanding how past romantic relationships influence people’s expectations about relationships and, by extension, their health and wellbeing.     

Your goals or mine? Women’s personal and vicarious eating regulation goals and their partners’ perceptions of support,well-being,and relationship quality

This research examined the types of eating regulation goals that women have for themselves as well as for their romantic partner, and how these relate to their interpersonal style toward their partner, and to their partner’s psychological and relational well-being. Participants were 131 heterosexual couples. Results show that the eating regulation goals that women have for their partner (health or appearance oriented) reflect the type of goals that they personally pursue. Furthermore, women who have health-focused eating goals for their partner are perceived as more autonomy-supportive, which is associated with the partner’s report of higher relationship quality. Conversely, women who have appearance-focused eating goals for their partner are more likely to be perceived as controlling, which negatively predicts the partner’s psychological and relational well-being. These results attest to the importance of considering women’s personal eating regulation goals for a better understanding of the type of goals they have for their partners and how these relate to their partners’ well-being and relationship quality.     

New Evidence for the Social Embeddedness of Infants' Early Triangular Capacities

Infants appear to be active participants in complex interactional sequences with their parents far earlier than previously theorized. In this report, we document the capacity of 3‐month‐old infants to share attention with two partners (mothers and fathers) simultaneously, and trace links between this capacity and early family group‐level dynamics. During comprehensive evaluations of the family's emergent coparenting alliance completed in 113 homes, we charted infants' eye gaze patterns during two different mother‐father‐infant assessment paradigms. Triangular capacities (operationalized as the frequency of rapid multishift gaze transitions between parents during interactions) were stable across interaction context. Infants exhibiting more advanced triangular capacities belonged to families showing evidence of better coparental adjustment. Theoretical and practice implications of these findings are discussed.     

The development of Japanese mother–infant feeding interactions during the weaning period

During the weaning period, infants are not skilled at self-feeding and caregivers play a prominent role in feeding. Solid feeding is therefore an inherently collaborative and interactive process between infants and caregivers. The present study examined how caregivers and infants coordinate their solid feeding interactions, based on naturalistic longitudinal observations of three Japanese mother–infant dyads. The main results were as follows. Four or five months after weaning (about 10–11 months of age), children's mouth movements and mothers’ arm movements became more synchronized, and the success or failure of coordinated feeding became independent on children's gaze behavior. During this same period, both mothers’ and children's body movements accelerated. Specifically, children's food-intake motions and mothers’ food-carrying movements became faster together, although before 10–11 months fluctuations of these motions were not as correlated. Finally, at 9–11 months of age rhythmic body movements became frequent. From the first day of weaning, all three mothers swayed their bodies rhythmically while feeding, and about 2–3 months later their children also began to sway as they ate, at first infectiously but later spontaneously. These observations indicate how specific behavioral development contributes to mother–infant coordination in feeding.     

Infants’ behavioral styles in joint attention situations and parents’ socio-economic status

In this study the eco-cultural model of parenting (Keller, H. (2007). Cultures of infancy. Mahwah, NJ: Erlbaum) was applied to the study of joint attention behavior of children from families with different socio-economic status (SES). It was hypothesized that infants’ early communication styles would differ with SES reflecting more independent or interdependent interactions with their caregivers. It was also hypothesized that infants would use the same types of behaviors whether they have declarative or imperative communication goals. The Early Social Communication Scales (ESCS, Mundy et al., 2003) was administered to 103 typically developing infants of 12 months (approximately half of them siblings of children with autism). A factor analysis, yielding four behavioral factors, namely pointing, eye contact, actions and following points, confirmed the hypothesis that infants use behaviors consistently across situations independent of their communicative intent. MANOVAs (comprising parental education and income) revealed that higher SES infants showed actions more frequently in the ESCS whereas lower SES infants followed experimenter's points more frequently. The results are discussed in the context of presumably differing socialization goals for infants and the divergent contribution of parental education and income that seem to have additive contribution to some factors (actions, following points) but divergent contributions to others (pointing, eye contact).     

‘What's New?’ at the Dinner Table: Family Dynamics During Mealtimes in Two Cultural Groups in Hawaii

This study shows systematic differences in how parents structure mealtime discourse in two cultural groups in Hawaii. Fifty-nine families were videotaped during week-day evening meals at home. Thirty of the families were middle-class Japanese-American (JA) families; 29 were middle-class Caucasian-American (CA) families. Evening meals in the Caucasian-American homes in this sample are clear-cut events. Families sit at tables and talk throughout the meal. Children are encouraged to describe their experiences, wishes, plans and perceptions. Parents cue children to focus on distinctive aspects of their realities, to talk about ‘what's new’, or unfamiliar to the audience. Evening meals in the Japanese-American homes are less focused on formal discussion. Half the families watch television while eating; others play games, cook, listen to music, talk on the phone or play with babies or pets during dinner. JA family members talk to each other less and structure their discourse differently. Rather than report on distinct, individual experiences, JA family members co-narrate and comment on what they are collectively doing. The observed differences are related to cultural differences in construals of self and other. The cultural importance of being able to clearly communicate individual realities across separate beings is seen in the CA mealtimes. Appreciation of smooth, group process and coordinated belonging is seen in the JA evening meals.     

SEQUENTIAL APPLICATION OF CAREGIVER TRAINING TO IMPLEMENT PEDIATRIC FEEDING PROTOCOLS

The purpose of this study was to evaluate the effectiveness of current caregiver training practices by implementing training components sequentially, to teach parents mealtime protocols. A multiple baseline design was implemented across two caregiver dyads. Therapist‐fed meals were conducted prior to training to identify an effective intervention to increase food acceptance and decrease food refusal. The package consisted of seven components: observation, written and verbal protocol review, video review, structured observation, modeling, role play, and immediate feedback. Correct implementation of mealtime protocols, by caregivers, were evaluated throughout the training process by having caregivers conduct meal sessions following each training component to determine if additional training was necessary. Results showed that the training procedures were effective in teaching caregivers to implement mealtime protocols, and systematic introduction of the training components produced systematic and incremental changes in correct caregiver implementation. In addition, all participants completed training without requiring all seven training components. Copyright © 2012 John Wiley & Sons, Ltd.     

A complex systems perspective on psychedelic brain action

Recent findings suggesting the potential transdiagnostic efficacy of psychedelic-assisted therapy have fostered the need to deepen our understanding of psychedelic brain action. Functional neuroimaging investigations have found that psychedelics reduce the functional segregation of large-scale brain networks. However, beyond this general trend, findings have been largely inconsistent. We argue here that a perspective based on complexity science that foregrounds the distributed, interactional, and dynamic nature of brain function may render these inconsistencies intelligible. We propose that psychedelics induce a mode of brain function that is more dynamically flexible, diverse, integrated, and tuned for information sharing, consistent with greater criticality. This ‘meta’ perspective has the potential to unify past findings and guide intuitions toward compelling mechanistic models.     

The Association between Symptom Accommodation and Emotional Coregulation in Couples with Binge Eating Disorder

Intense negative emotions and maladaptive behavioral strategies to reduce emotional distress occur not only in patients with various forms of psychopathology but also in their committed partners. One common strategy to reduce distress is for partners to accommodate to the symptoms of the disorder, which reduces distress short term but maintains symptoms long term. Accommodation is believed to be motivated by the partner reacting behaviorally to the patient's emotions, but the emotions of the partner in this context have yet to be examined. This pilot study examined how partner accommodation related to specific patterns of emotional coregulation between patients with binge eating disorder (BED) and their partners, before and after a couple‐based intervention for BED. Vocally encoded emotional arousal was measured during couples’ (n = 11) conversations about BED. As predicted, partners’ emotional reactivity to patients’ emotional arousal was associated with high accommodation before treatment. Thus, partners may use accommodation as a strategy to reduce both the patients’ and their own distress. After treatment, partners’ arousal was no longer associated with the patients’ emotional arousal; instead, partners showed greater emotional stability over time, specifically when accommodation was low. Additionally, patients were less emotionally aroused after treatment. Therefore, treatment may have decreased overall emotionality of patients and altered the association between accommodation and partners’ emotional reactivity. If replicated, this understanding of the emotional context associated with accommodation in BED can inform couple‐based treatment by targeting specific emotional precipitants of behaviors that maintain symptoms.     

Family Mealtimes and Family Functioning

ABSTRACT

This study contributes to the existing research literature by assessing how the frequency of family mealtimes correlates with family communication and life satisfaction. Participants consisted of 50 families from the Southeastern United States. Parent and child participants completed measures assessing frequency of family mealtime, family communication, and family satisfaction. Results indicated that, based on parent-report, the frequency of all family members eating dinner together was significantly and positively correlated with both family communication and family satisfaction. Implications of findings highlight the importance of encouraging regular mealtime interactions among families.
