12‐Month‐Olds Produce Others' Intended but Unfulfilled Acts

Following Meltzoff's (1995) behavioral reenactment paradigm, this study investigated the ability of 12‐month‐olds (N = 44) to reproduce a model's attempted‐but‐failed actions on objects. Testing was conducted using a novel set of objects designed to enable young infants to readily identify the potential outcome of the model's actions. Infants who saw an adult's attempted‐but‐failed actions now produced her intended outcomes at an equivalent rate to infants who saw the model's completed acts, and significantly more so than infants who either observed an adult manipulating the test apparatus using nontarget actions or who did not see any actions demonstrated on the test apparatus. This result shows that, contrary to previous studies, 12‐month‐olds can produce the intended but unconsummated acts of others.     

Is a Bird an Apple? The Effect of Speaker Labeling Accuracy on Infants' Word Learning,Imitation, and Helping Behaviors

This study examined infants' sensitivity to a speaker's verbal accuracy and whether the reliability of the speaker had an effect on their selective trust. Forty‐nine 18‐month‐old infants were exposed to a speaker who either accurately or inaccurately labeled familiar objects. Subsequently, the speaker administered a series of tasks in which infants had an opportunity to: learn a novel word, imitate the speaker's “irrational” actions, and help the speaker obtain an out‐of‐reach object. In contrast to infants in the accurate (reliable) condition, those in the inaccurate (unreliable) condition performed more poorly on a word‐learning task and were less likely to imitate. All infants demonstrated high rates of instrumental helping behavior. These results are the first to demonstrate that infants as young as 18 months of age cannot only detect a speaker's verbal inaccuracy but also use this information to attenuate their word recognition and learning of novel actions.     

Relations Between Mother‐Child Interactions and the Neural Correlates of Face Processing in 6‐Month‐Olds

Developmental studies of face processing have revealed age‐related changes in how infants allocate neurophysiological resources to the face of a caregiver and an unfamiliar adult. We hypothesize that developmental changes in how infants interact with their caregiver are related to the changes in brain response. We studied 6‐month‐olds because this age is frequently noted in the behavioral and neurophysiological literature as a time of transition in which infants begin to discriminate more readily between caregivers and unfamiliar adults. We used infants' behavioral responses to an original behavioral paradigm to predict event‐related potential (ERP) responses to pictures of the mother's face and a stranger's face in the same group of participants. Our results suggest that individual differences in infants' proximity‐seeking behaviors during interactions with the mother correlate with their neurophysiological responses to the mother's face as opposed to an unfamiliar face for the Nc component of the ERP. These results have implications for understanding the role of the changing infant‐caregiver relationship on the development of the face processing system in early infancy.     

Smartphone and social media addiction: Exploring the perceptions and experiences of Canadian teenagers

“Addiction” to internet‐connected technology continues to dominate media discourses of young people. Researchers have identified negative outcomes, including decreased mental health, resulting from anxieties related to technology, e.g., a fear of missing out and social connectivity related to online technologies. Not enough is known, however, regarding young people's own responses to these ideas. This paper highlights discussions with teenagers around the idea of internet addiction, exploring their experiences and perceptions regarding the idea that “kids today” are addicted to their devices, especially smartphones and the social network sites they often access from them. Thirty‐five focus group discussions with 115 Canadian teenagers (aged 13–19 years old) center on their use of information communication technologies, especially contemporary social network sites such as Snapchat, Instagram and Facebook. Our discussions reveal (1) that teens are actively embracing the label of addiction; (2) their ironic positioning occurs despite a felt sense of debased agency in relation to the power of the algorithms and affordances of the technologies mediating their use; and (3) rather than a stark divide between adults as “digital immigrants” versus young people as “digital natives,” our teens positioned themselves in contrast to both their parents and younger siblings, both of whom are criticized as addicted themselves. A consistent theme is the influence of peer groups who socially compel addictive behaviours, including the fear of missing out, rather than the technologies per se. Wider implications for thinking beyond solely young people as suffering from online addiction are considered.     

Cry Babies and Pollyannas: Infants Can Detect Unjustified Emotional Reactions

Infants are attuned to emotional facial and vocal expressions, reacting most prominently when they are exposed to negative expressions. However, it remains unknown if infants can detect whether a person's emotions are justifiable given a particular context. The focus of the current paper was to examine whether infants react the same way to unjustified (e.g., distress following a positive experience) and justified (e.g., distress following a negative experience) emotional reactions. Infants aged 15 and 18 months were shown an actor experiencing negative and positive experiences, with one group exposed to an actor whose emotional reactions were consistently unjustified (i.e., did not match the event), while the other saw an actor whose emotional reactions were justified (i.e., always matched the event). Infants' looking times and empathic reactions were examined. Only 18‐month‐olds detected the mismatching facial expressions: Those in the unjustified group showed more hypothesis testing (i.e., checking) across events than the justified group. Older infants in the justified group also showed more concerned reactions to negative expressions than those in the unjustified group. The present findings indicate that infants implicitly understand how the emotional valence of experiences is linked to subsequent emotional expressions.     

Assessing Speech Discrimination in Individual Infants

Assessing speech discrimination skills in individual infants from clinical populations (e.g., infants with hearing impairment) has important diagnostic value. However, most infant speech discrimination paradigms have been designed to test group effects rather than individual differences. Other procedures suffer from high attrition rates. In this study, we developed 4 variants of the Visual Habituation Procedure (VHP) and assessed their robustness in detecting individual 9‐month‐old infants' ability to discriminate highly contrastive nonwords. In each variant, infants were first habituated to audiovisual repetitions of a nonword (seepug) before entering the test phase. The test phase in Experiment 1 (extended variant) consisted of 7 old trials (seepug) and 7 novel trials (boodup) in alternating order. In Experiment 2, we tested 3 novel variants that incorporated methodological features of other behavioral paradigms. For the oddity variant, only 4 novel trials and 10 old trials were used. The stimulus alternation variant was identical to the extended variant except that novel trials were replaced with “alternating” trials—trials that contained repetitions of both the old and novel nonwords. The hybrid variant incorporated elements from both the oddity and the stimulus alternation variants. The hybrid variant proved to be the most successful in detecting statistically significant discrimination in individual infants (8 out of 10), suggesting that both the oddity and the stimulus alternation features contribute to providing a robust methodology for assessing discrimination in individual infants. In Experiment 3, we found that the hybrid variant had good test‐retest reliability. Implications of these results for future infant speech perception work with clinical populations are discussed.     

Eighteen‐Month‐Old Infants Correct Non‐Conforming Actions by Others

At around their third birthday, children begin to enforce social norms on others impersonally, often using generic normative language, but little is known about the developmental building blocks of this abstract norm understanding. Here, we investigate whether even toddlers show signs of enforcing on others interpersonally how “we” do things. In an initial dyad, 18‐month‐old infants learnt a simple game‐like action from an adult. In two experiments, the adult either engaged infants in a normative interactive activity (stressing that this is the way “we” do it) or, as a non‐normative control, marked the same action as idiosyncratic, based on individual preference. In a test dyad, infants had the opportunity to spontaneously intervene when a puppet partner performed an alternative action. Infants intervened, corrected, and directed the puppet more in the normative than in the non‐normative conditions. These findings suggest that, during the second year of life, infants develop second‐personal normative expectations about their partner's behavior (“You should do X!”) in social interactions, thus making an important step toward understanding the normative structure of human cultural activities. These simple normative expectations will later be scaled up to group‐minded and abstract social norms.     

Toward a Sociology of Nature

Although we often believe that nature stands apart from social life, our experience of nature is profoundly social. This paper unpacks this paradox in order to (1) explain sociology's neglect of the environment and (2) introduce the articles in this special issue on “the sociology of nature.” I argue that sociology's disinterest in the biophysical world is a legacy of its classical concern with tracing society's “Great Transformation” from gemeinschaft to gesellschaft: while early anthropologists studied “primitive” societies that allegedly had not yet completed “the passage from nature to culture” (Lévi‐Strauss 1963 : 99), pioneering sociologists presumed that industrialization and urbanization liberated “modern” society from nature and therefore focused their attention on “urbanism as a way of life” (Wirth 1938 ). As exemplified by the articles in this symposium, environmental sociology critiques the nature‐culture and town‐country dualisms. One of environmental sociology's core contributions has been demonstrating that nature is just as much a social construction as race or gender; however, its more profound challenge to the discipline lies in its refutation of the sociological axiom that social facts can be explained purely through reference to other social facts. “Environmental facts” are a constitutive feature of social life, not merely an effect of it.     

Marital Conflict and Children's Emotions: The Development of an Anger Organization

The aim of this study was to examine the relationship between anger‐based marital conflict and the development of an anger organization in children between the ages of 4 and 8 years old. Anger organization was defined as an adversarial approach to relationships demonstrated through (a) short‐term anger expressions during social interaction and (b) aggression in relationships. Seventy‐one children from diverse socioeconomic backgrounds, their mothers, and their teachers participated in the study. Mothers completed questionnaires on anger‐based marital conflict and on children's aggression. Sociometric ratings of anger and aggression were obtained from peers. Teachers supplied reports of children's aggression. Children's short‐term emotional expression and the circumstances that elicited emotions were observed during peer interaction. Anger‐based marital conflict was found to be strongly associated with peer, maternal, and teacher reports of aggression, but not with reports of internalizing symptomatology. Anger‐based marital conflict was also associated with short‐term anger expressions, but not with short‐term expressions of sadness. I argue that children develop an emotional organization in which anger predominates when they are exposed to high levels of anger‐based marital conflict.     

Fine‐Grained Analysis of Motionese: Eye Gaze,Object Exchanges,and Action Units in Infant‐Versus Adult‐Directed Action

Mothers modify their actions when demonstrating objects to infants versus adults. Such modifications have been called infant‐directed action (IDA) or motionese (Brand, Baldwin, & Ashburn, 2002). We investigated the IDA features of interactiveness and simplification by quantifying eye gaze, object exchanges, and action units enacted between exchanges in 42 mothers' demonstrations of novel objects to infants (6–8 months or 11–13 months) or adults. We found more eye gaze, more object exchanges, and fewer action types per turn in demonstrations to infants relative to adults. Unlike prior research using global measurements, we detected differences in behavior directed at infants of different ages: Shorter, more frequent gazes and more exchanges characterized demonstrations to older versus younger infants. These findings indicate the fruitfulness of fine‐grained analysis of IDA, and further clarify how adults may support infants' processing of human motion.     

ACKNOWLEDGMENT OF GUEST REVIEWERS

This study explored 14‐month‐old infants' ability to form novel word‐spatial relation associations. During habituation, infants heard 1 novel word (e.g., teek) while viewing dynamic containment events (i.e., Big Bird placed in a box) and, on other habituation trials, a second novel word (e.g., blick) while viewing dynamic support events (i.e., Big Bird placed on the box). Each novel word was presented in a sentence (e.g., “She's putting Big Bird teek the box”). During the test, infants discriminated an event that maintained the habituation word‐relation pairing from one that presented a switch in this pairing. The results indicate that 14‐month‐olds can learn to form word‐relation associations quickly, requiring only a few minutes of experience with each word‐relation pairing.     

Limits on Infants' Ability to Dynamically Update Object Representations

Like adults, infants use working memory to represent occluded objects and can update these memory representations to reflect changes to a scene that unfold over time. Here we tested the limits of infants' ability to update object representations in working memory. Eleven‐month‐old infants participated in a modified foraging task in which they saw 2 quantities of crackers sequentially hidden in buckets and then were allowed to choose between them. We manipulated the working memory demands of the task by either hiding crackers in direct succession (i.e., infants saw all of the crackers hidden in the first location, then saw all of the crackers hidden in the second location), or hiding them in alternation (i.e., infants saw some crackers hidden in the first location, then saw some crackers hidden in the second location, then saw more crackers hidden in the first location). Across 6 experiments we found that infants successfully updated their representations of the hidden arrays when crackers were presented in succession. However, when crackers were hidden in alternation and infants had to reupdate an array that was no longer in the current focus of attention, infants showed a striking pattern of failure. These results suggest that, for infants as well as for adults, the flexibility of working memory is subject to processing constraints.     

Choosing Childlessness: Weber's Typology of Action and Motives of the Voluntarily Childless*

There has been little in‐depth theoretical study in sociology of the motives of women and men who are childless by choice. This article begins to remedy this deficiency by analyzing the motives articulated by twenty‐three childless women and men using Weber's typology of social action and distinction between primary and end motives. In‐depth interview and focus group data reveal that, compared to men, women more often were affected by the parenting models of significant others, saw parenting as conflicting with career and leisured identities, and claimed the lack of a “maternal instinct” or disinterest in children as dominant influences. Men more explicitly than women rejected parenthood because of its perceived sacrifices, including financial expense. Both women and men were motivated by personality traits that they deemed incongruent with good parenting. Declared motives especially demonstrated instrumentally rational action in Weber's schema, although affectual and value‐rational actions also were present. Respondent motives are compared to those that they, and empirical studies, have attributed to parents.     

Mothers' Verbal and Nonverbal Strategies in Relation to Infants' Object‐Directed Actions in Real Time and Across the First Three Years in Ethnically Diverse Families

We examined maternal behavioral strategies in relation to infants' object‐directed actions in real time and over developmental time in 206 mother–infant dyads from African American, Dominican immigrant, and Mexican immigrant backgrounds. Mothers were asked to share a set of beads and strings with their infants when children were 14, 24, and 36 months. We coded three types of maternal strategies—eliciting attention, instructive assistance, and encouragement—which could be expressed verbally (e.g., “look”, “turn it”, “good job!”) or physically (i.e., through gestures, hands‐on guidance, or transfer of objects). We also coded infants' unassisted bead‐stringing. Across ethnic groups and ages, mothers' hands‐on guidance and object transfer increased the likelihood that infants would follow with unassisted bead‐stringing during real‐time interaction. Over developmental time, mothers modified their strategies: They displayed fewer attention‐getting strategies and more encouragement across infant ages, and peaked in their provision of instructive assistance when infants were 24 months. Additionally, Mexican mothers displayed more nonverbal strategies (e.g., gestures, hands‐on guidance) than did African American and/or Dominican mothers, who displayed more verbal strategies (e.g., attention‐getting and encouraging language). Developmental and real‐time patterns in mother–infant object‐related interactions generalize across ethnicities, although mothers' emphases on specific strategies are culture specific.     

Where It's At! The Role of Best Friends and Peer Group Members in Young Adults' Alcohol Use

We examined the hypothesis that best friends and members from a broader peer group would not differ in the amount of influence they have on young adults' alcohol consumption and that what counts would be the mere presence of drinking peers in a given context—irrespective of the type of relationship such peers would have with the target young adult. Data were used from a naturalistic observation study that was conducted in a “bar‐lab” among 221 young adults aged 18–25 years. Both hierarchical and multilevel regression analyses showed that group effects (i.e., average group levels of alcohol consumption) explained young adults' drinking. When taking into account these group effects, best friends' alcohol consumption in the bar‐lab was a nonsignificant predictor of young adults' alcohol use—although best friends' questionnaire‐assessed drinking did predict alcohol consumption in the bar‐lab.     

Sensitivity to Social Contingency and Positive Emotion in 2‐Month‐Olds

This study was aimed at sorting out conflicting results in the literature concerning 2‐month‐olds' sensitivity to interpersonal contingency, and investigated the potential role of infants' positive emotion in contingency detection. Infants were randomly assigned to an experimental group (EG) that was presented an uninterrupted live–replay–live sequence of three 30‐sec episodes of their mothers' communicative behavior using a double video TV paradigm, or to a control group (CG) that was presented an uninterrupted 90 sec of contingent maternal interactions. Infants of the EG grimaced more than infants of the CG only during the 2nd period of social exchange (replay vs. 2nd live period), but there was an increase of grimacing and a reduction in gazing during the 3rd period of televised interactions in infants of the CG. Each group was split into 2 subgroups a posteriori according to the presence or absence of smiling during the 1st contingent episode. Smiling infants of the EG reacted more negatively during the 2nd interaction period compared to other subgroups. These findings support the view that sensitivity, not fatigue or loss of interest to maternal stimulation, accounts for 2‐month‐olds' expressive changes during noncontingent maternal interactions; fatigue or loss of interest better explains the decline in attention and the increase of negative expressiveness during the last period of contingent interaction. The findings also suggest that the emotional climate of dyadic exchanges could be a contributing factor to infants' ability to detect the relations between their own actions and those of their social partners.     

Older adults' frequent visits to a fast-food restaurant: Nonobligatory social interaction and the significance of play in a “third place”

How might older adults' nonobligatory social interactions in a “third place” be described and interpreted? The ethnographic methodology, primarily participant observation, was used to gather data from a naturally occurring group of older adults who frequent a fast-food restaurant. Emerging themes include the concept of sociability, play, and laughter. Findings suggest that: (a) older adults congregate at this fast-food restaurant to be with their buddies “to play”; (b) the group is fun for members and there are lots of laughter; (c) group membership in this “third place” provides structure, meaning, and opportunities for these older adults to engage in personal expression; and (d) the members are sociable, but relatively little social support is exchanged.     

The backstage work negotiators do when communicating with persons in crisis

When a person in crisis threatens suicide, police negotiators engage them in a conversation to prevent death. Working in small teams, the primary negotiator's role is to talk directly to the person in crisis. A secondary negotiator, working “behind the scenes,” supports the ongoing negotiation. Using 31 hours of audio‐recorded British negotiations, we uncover the backstage work of secondary negotiators. We use conversation analysis to identify the sequential position, linguistic form, and action of the secondary negotiator's interventions on (1) the delivery (e.g. “sound angry”) and (2) next actions (e.g. “say please,” “try asking them to move”) of the primary negotiator, and how the primary incorporates them into the negotiation. Our analysis shows that, while some suggestions were effective, others disrupted the flow of the negotiation as well as the alignment between primary negotiator and person in crisis. The paper augments current sociolinguistic understandings of the high‐stakes language activity of crisis negotiation and highlights the importance of attending to linguistic features of interaction when training negotiators to work better as a team.     

Infant Brain Responses to Object Weight: Exploring Goal‐Directed Actions and Self‐Experience

Recent work has suggested the value of electroencephalographic (EEG) measures in the study of infants' processing of human action. Studies in this area have investigated desynchronization of the sensorimotor mu rhythm during action execution and action observation in infancy. Untested but critical to theory is whether the mu rhythm shows a differential response to actions which share similar goals but have different motor requirements or sensory outcomes. By varying the invisible property of object weight, we controlled for the abstract goal (reach, grasp, and lift the object), while allowing other aspects of the action to vary. The mu response during 14‐month‐old infants' own executed actions showed a differential hemispheric response between acting on heavier and lighter objects. EEG responses also showed sensitivity to “expected object weight” when infants simply observed an experimenter reach for objects that the infants' prior experience indicated were heavier vs. lighter. Crucially, this neural reactivity was predictive—during the observation of the other reaching toward the object, before lifting occurred. This suggests that infants' own self‐experience with a particular object's weight influences their processing of others' actions on the object, with implications for developmental social‐cognitive neuroscience.     

Becoming a Communicative Partner: Infant Contingent Responsiveness to Maternal Language and Gestures

Infant contingent responsiveness to maternal language and gestures was examined in 190 Mexican American, Dominican American, and African American infant–mother dyads when infants were 14 and 24 months. Dyads were video‐recorded during book‐sharing and play. Videos were coded for the timing of infants’ vocalizations and gestures and mothers’ referential language (i.e., statements that inform infants about objects and events in the world; e.g., “That's a big doggy!”), regulatory language (i.e., statements that regulate infants’ attention or actions; e.g., “Look at that”, “Put it down!”), and gestures. Infants of all three ethnicities responded within 3 sec of mothers’ language and gestures, increased their responsiveness over development, and displayed specificity in their responses: They vocalized and gestured following mothers’ referential language and gestures, but were less likely than chance to communicate following mothers’ regulatory language. At an individual level, responsive infants had responsive mothers.
