Humour Perception and Creation between Parents and 3‐ to 6‐month‐old Infants

Humour and laughter are universal to the human psychological experience and have serious developmental and evolutionary implications. Despite the early emergence of laughter in infancy, infants have been largely ignored in the humour research and humour has been largely ignored in the infant research. The present study describes the emergence of humour perception and creation in a sample of 20 parent–infant dyads who were followed from ages 3‐to‐ 6 months. The study examined how infants discover that absurd nonverbal behaviour, known as ‘clowning’, is amusing in the context of social engagement with caregivers. Results indicate that parents primarily use clowning when attempting to amuse their infants and pair these behavioural absurdities with affective cues like smiling and laughing. As they got older, infants were more likely to laugh and smile in response to clowning. Infants' ability to create humor via clowning also increased with age, starting with simple shrieks at 3 months to imitating absurd actions by 5 months. These increases are partly potentially explained by accompanying increases in parental smiling, laughing and clowning in response to infant clowning. Future research should employ more diverse samples and experimentally investigate the role of parental affect and social referencing in infants' interpretation of absurd behavior.

Does contingency in adults’ responding influence 12-month-old infants’ social referencing?

In two experiments we examined the influence of contingent versus non-contingent responding on infant social referencing behavior. EXPERIMENT 1: Forty 12-month-old infants were exposed to an ambiguous toy in a social referencing situation. In one condition an unfamiliar adult who in a previous play situation had responded contingently to the infant’s looks gave the infant positive information about the toy. In the other condition an unfamiliar adult who previously had not responded contingently delivered the positive information. EXPERIMENT 2: Forty-eight 12-month-old infants participated in Experiment 2. In this experiment it was examined whether the familiarity of the adult influences infants’ reactions to contingency in responding. In one condition a parent who previously had responded contingently to the infant’s looks provided positive information about the ambiguous toy, and in the other condition a parent who previously had not responded contingently provided the positive information. The infants looked more at the contingent experimenter in Experimenter 1, and also played more with the toy after receiving positive information from the contingent experimenter. No differences in looking at the parent and in playing with the toy were found in Experiment 2. The results indicate that contingency in responding, as well as the familiarity of the adult, influence infants’ social referencing behavior.

Social referencing in 10-month-old infants

In Experiment 1, forty 10-month-old infants participated together with an experimenter and a parent in a social referencing encounter. The experimenter or the parent presented an ambiguous toy. Neither of the adults provided information about the toy in order to examine infant spontaneous looking behaviour. The infants looked more at both adults when the experimenter presented the toy. In Experiment 2, forty-four 10-month-old infants participated. The experimenter or the parent provided positive information about an ambiguous toy. The infants played more with the toy when the experimenter provided information than when the parent did. The results are discussed in terms of seeking information from knowledgeable others in ambiguous situations.     

Parents’ moral intentions towards antisocial parent behaviour: An identity approach in youth sport

ObjectivesGrounded in personal and social identity theory, the purpose of this study was to examine whether parents’ personal and social identity perceptions influence their moral intentions towards antisocial parent behaviour in a youth sport setting.DesignParents of competitive youth ice hockey players (N = 437) read a vignette that either described a parent from the participant’s own team (i.e., ingroup), or a parent from an opposing team (i.e., outgroup) acting antisocially towards an athlete from the participant’s own team, an opposing athlete, or their own child. Parents were asked whether they would respond to the antisocial behaviour in the form of direct or indirect criticism or report the behaviour to the coach or to the league.ResultsParents were more likely to directly criticize ingroup parents than outgroup parents and they were more likely to indirectly criticize outgroup parents than ingroup parents. Further, parents with stronger social identities reported higher intentions to indirectly criticize an outgroup parent. There were no main effects for reporting behaviour (to coach or league), and personal identity did not moderate relationships with moral intentions towards antisocial behaviour.ConclusionBy providing parents with a situation that includes antisocial parent behaviour in the immediate youth sport environment, novel insight was gathered with regard to what contextual elements might drive parents’ intention to criticize, but not report antisocial behaviour.     

Uncertainty matters: impact of stimulus ambiguity on infant social referencing

Most infant social referencing studies have assumed that infants would be more likely to engage in social looking and be influenced by adults' message when a context is ambiguous. The present study empirically tested the effect of stimulus ambiguity on infants' referencing behaviours, with three different stimuli (positive, ambiguous, and negative), two different messages (happy and fearful), two different message providers (mother and stranger), and in two age groups (12 and 16 month olds). A typical social referencing paradigm was used and infants' social looking and regulation were measured. Infants looked at adults more frequently and faster during ambiguous situations than during unambiguous situations. They also tended to regulate their affect and behaviour based on adults' message only towards ambiguous toys. Older infants tended to look at adults faster, and showed stronger reactions towards ambiguous stimuli than younger infants, suggesting that infants' social development may moderate the effect of stimulus ambiguity on social referencing. Overall, results indicated that the ambiguity postulate is a legitimate assumption for infant social referencing. Copyright © 2010 John Wiley & Sons, Ltd.     

Early humour production

The current studies explored early humour as a complex socio‐cognitive phenomenon by examining 2‐ and 3‐year‐olds’ humour production with their parents. We examined whether children produced novel humour, whether they cued their humour, and the types of humour produced. Forty‐seven parents were interviewed, and videotaped joking with their children. Other parents (N= 113) completed a survey. Parents reported children copy jokes during the first year of life, and produce novel jokes from 2 years. In play sessions, 3‐year‐olds produced mostly novel humorous acts; 2‐year‐olds produced novel and copied humorous acts equally frequently. Parents reported children smile, laugh, and look for a reaction when joking. In play sessions, 2‐ and 3‐year‐olds produced these behaviours more when producing humorous versus non‐humorous acts. In both parent reports and play sessions, they produced novel object‐based (e.g., underwear on head) and conceptual humour (e.g., ‘pig says moo’) and used wrong labels humorously (e.g., calling a cat a dog). Thus, parent report and child behaviour both confirm that young children produce novel humorous acts, and share their humour by smiling, laughing, and looking for a reaction.     

The structure of feared social situations among individuals with a lifetime diagnosis of social anxiety disorder in two independent nationally representative mental health surveys

The present study employed both exploratory and confirmatory factor analytic approaches with nationally representative samples of individuals with a lifetime diagnosis of social anxiety disorder (n=1123; n=3091, respectively) using split-halves of the National Comorbidity Replication Survey (n=9282) and cross-validated with the Canadian Community Health Survey on Mental Health and Wellbeing (n=36,984). Strong support was found for a three-factor solution. This model was obtained from exploratory factor analysis and was further evaluated using two confirmatory factor analytic investigations in the two national samples. The three social situational domains reflected (1) Social Interaction Fears, (2) Observation Fears, and (3) Public Speaking Fears. Individuals with generalized social anxiety disorder (i.e., those who endorsed 7 or more of 13 feared social situations assessed in the survey) were significantly more likely to report Social Interaction Fears and Observation Fears compared to individuals with non-generalized social anxiety disorder (i.e., those who endorsed only 6 or fewer of 13 feared social situations). Individuals with generalized social anxiety were particularly characterized by combinations of Public Speaking Fears plus Social Interaction Fears and Observation Fears. The clinical and classification implications of our study for DSM-V are discussed.     

Infant–mother social referencing interactions: Description and antecedents in maternal sensitivity and infant irritability

The purpose of the study was to describe naturally occurring infant and maternal behaviours in terms of social referencing in a stranger wariness situation, and to explore antecedents to such behaviouts in early maternal sensitivity and infant irritability. One hundred and ten 10-months-old infants and their mothers were videotaped. Infant social referencing behaviour was defined as puzzled looks directed at mother's face after the infant had discovered the stranger. Almost half of the infants looked with a puzzled expression at their mothers immediately after discovering the stranger, and a majority of the mothers sent a positive message back to the infants. Twenty per cent of the infants never looked at their mothers and 20% of the mothers did not respond when their infants turned to them. Infants whose mothers had responded positively to the referencing look showed positive responses to the stranger to a higher degree than infants who did not reference or those who were not responded to. Antecedents to infant and mother interactive behaviours were sought in maternal sensitivity (general sensitivity, physical contact, responsiveness, intrusiveness, response to distress, and effectiveness in comforting) and in infant irritability as observed when the infants were 4 months old. It was found that infants who did not reference their mothers for information at 10 months had experienced less sensitive mothering 6 months earlier and had also shown more irritability.     

The informative value of emotional expressions: 'social referencing' in mother-child pretense

Mothers begin to pretend with their children during the second year, when children still have much to learn about the real world. Although it would be easy to confuse what is pretend with what is real, children at this young age often demonstrate comprehension during pretense situations. It is plausible that social referencing, in which the child uses the mother's emotional expression as a guide to behavior, might facilitate this emerging knowledge by signaling to the child not to take the pretend situation seriously. Data from 32 pairs of mothers and their 18-month-olds who had engaged in pretend and real snack behaviors were subjected to a sequential analysis to investigate a social referencing interpretation. Consistent with our hypothesis, behaviors suggestive of a baby's understanding pretense were more likely to follow a specific combination of behaviors consistent with social referencing than other combinations of behaviors. These results provide support for the possibility that children use information obtained through social referencing to assist understanding during pretense interactions.     

Social referencing in infants of mothers with symptoms of depression

The present study examined the acquisition of social referencing skills in infants of mothers with symptoms of depression (n = 44). We aimed to determine if a short discrimination training could facilitate infants’ social referencing. Mothers were instructed to pose either joyful or fearful facial expressions to cue infants’ approach/avoidance responses toward an ambiguous object. Maternal expressions were correlated with pleasant or unpleasant events occurring after the infant's response. The results showed that after the intervention, infants looked at their mothers more frequently and reached or avoided the ambiguous object based on the preceding maternal expression. The results suggest that discrimination training procedures can establish social referencing in infants of mothers with symptoms of depression.     

Infants prefer to imitate a reliable person

Research has shown that preschoolers prefer to learn from individuals who are a reliable source of information. The current study examined whether the past reliability of a person's emotional signals influences infants’ willingness to imitate that person. An emotional referencing task was first administered to infants in order to demonstrate the experimenter's credibility or lack thereof. Next, infants in both conditions watched as the same experimenter turned on a touch light using her forehead. Infants were then given the opportunity to reproduce this novel action. As expected, infants in the unreliable condition developed the expectation that the person's emotional cues were misleading. Thus, these infants were subsequently more likely to use their hands than their foreheads when attempting to turn on the light. In contrast, infants in the reliable group were more likely to imitate the experimenter's action using their foreheads. These results suggest that the reliability of the model influences infants’ imitation.     

Development of hand preference in the Colorado Adoption Project

A longitudinal study of the development of hand preference in 152 adopted and 120 nonadopted (control) infants measured in natural behavioral situations at both 12 and 24 mo. of age is reported. Significant developmental trends were observed for both increasing strength and direction of handedness. Less than 10% of the infants exhibited a clear preference at 12 mo. of age, whereas about 30% were lateralized at 24 mo., with more boys than girls being left-handed. In contrast, over 90% of the parents of these children (both biological and adoptive parents of the adopted children and parents of the nonadopted children) were lateralized. Perhaps because so few infants were lateralized at either age, parent-offspring resemblances were inconsistent and the number of significant parent/child correlations was about that expected on the basis of chance alone.     

Digital disruption? Maternal mobile device use is related to infant social‐emotional functioning

Mobile device use has become increasingly prevalent, yet its impact on infant development remains largely unknown. When parents use mobile devices in front of infants, the parent is physically present but most likely distracted and unresponsive. Research using the classic Still Face Paradigm (SFP) suggests that parental withdrawal and unresponsiveness may have negative consequences for children's social‐emotional development. In the present study, 50 infants aged 7.20 to 23.60 months (M = 15.40, SD = 4.74) and their mothers completed a modified SFP. The SFP consisted of three phases: free play (FP; parent and infant play and interact), still face (SF; parent withdraws attention and becomes unresponsive), and reunion (RU; parent resumes normal interaction). The modified SFP incorporated mobile device use in the SF phase. Parents reported on their typical mobile device use and infant temperament. Consistent with the standard SFP, infants showed more negative affect and less positive affect during SF versus FP. Infants also showed more toy engagement and more engagement with mother during FP versus SF and RU. Infants showed the most social bids during SF and more room exploration in SF than RU. More frequent reported mobile device use was associated with less room exploration and positive affect during SF, and less recovery (i.e., engagement with mother, room exploration positive affect) during RU, even when controlling for individual differences in temperament. Findings suggest that the SFP represents a promising theoretical framework for understanding the impact of parent's mobile device use on infant social‐emotional functioning and parent–infant interactions.     

The sustained effect of emotional signals on neural processing in 12‐month‐olds

Around the end of the first year of life, infants develop a social referencing ability – using emotional information from others to guide their own behavior. Much research on social referencing has focused on changes in behavior in response to emotional information. The present study was an investigation of the changes in neural responses that underlie social referencing behavior, reflected in event‐related potentials (ERPs). Twenty‐six 12‐month‐olds participated in a single‐session visit in which ERPs were recorded both immediately before and after a behavioral intervention in which infants' caregivers provided positive, negative or neutral information about each of three stimuli (ERP data available for n = 17). After the intervention, infants devoted more neural resources to processing negative versus neutral and positive information, as observed in early and late positive‐going components. Changes in neural responses from the pre‐ to post‐intervention recordings clarify this observation, indicating a sustained response in the negative and positive conditions, and a decrease in the neutral condition, suggesting an attenuation effect in the neutral condition. Further, infants who attended most to the objects in the behavioral intervention showed increased neural responses in the negative condition and decreased responses in the positive condition. Taken together, these findings suggest that infants' neural responses are differentially affected by positive, negative and neutral information. Furthermore, the findings highlight the importance of measuring the change in neural responses to better interpret post‐experience responses.     

Humour production may enhance observational learning of a new tool-use action in 18-month-old infants

Many studies have shown that making children laugh enhances certain cognitive capacities such as attention, motivation, perception and/or memory, which in turn enhance learning. However, no study thus far has investigated whether laughing has an effect on learning earlier in infancy. The goal of this study was to see whether using humour with young infants in a demonstration of a complex tool-use task can enhance their learning. Fifty-three 18-month-old infants participated in this study and were included either in a humorous or a control demonstration group. In both groups infants observed an adult using a tool to retrieve an out-of-reach toy. What differed between groups was that in the humorous demonstration group, instead of playing with the toy, the adult threw it on the floor immediately after retrieval. The results show that infants who laughed at the demonstration in the humorous demonstration group reproduced significantly more frequent target actions than infants who did not laugh and those in the control group. This effect is discussed with regard to individual differences in terms of temperament and social capacities as well as positive emotion and dopamine release.     

Some Beginnings of Word Comprehension in 6-Month-Olds

Previous studies of infants' comprehension of words estimated the onset of this ability at 9 months or later. However, these estimates were based on responses to names of relatively immobile, familiar objects. Comprehension of names referring to salient, animated figures (e.g., one's parents) may begin even earlier. In a test of this possibility, 6-month-olds were shown side-by-side videos of their parents while listening to the words "mommy" and "daddy." The infants looked significantly more at the video of the named parent. A second experiment revealed that infants do not associate these words with men and women in general. Infants shown videos of unfamiliar parents did not adjust their looking patterns in response to "mommy" and "daddy."     

Infant illness severity and family adjustment in the aftermath of NICU hospitalization

Up to 15% of parents have an infant who will spend time in a neonatal intensive care unit (NICU). After discharge, parents may care for a medically fragile infant and worry about their development. The current study examined how infant illness severity is associated with family adjustment. Participants included parents with infants who had been discharged from the NICU 6 months to 3 years prior to study participation (N = 199). Via a Qualtrics online survey, parents reported their infants’ medical history, parenting stress, family burden, couple functioning, and access to resources. Multivariable regression analyses revealed that more severe infant medical issues during hospitalization (e.g., longer length of stay and more medical devices) were associated with greater family burden, but not stress or couple functioning. Infant health issues following hospitalization (i.e., medical diagnosis and more medical specialists) were associated with greater stress, poorer couple functioning, and greater family burden. Less time for parents was associated with increased stress and poorer couple functioning. Surprisingly, parents of infants who were rehospitalized reported less stress and better couple functioning, but greater family burden. Family-focused interventions that incorporate psychoeducation about provider−patient communication, partner support, and self-care may be effective to prevent negative psychosocial sequelae among families.     

Siblings’ Understanding of Teaching in Early and Middle Childhood:‘Watch Me and You’ll Know How to Do It’

This study examined siblings’ knowledge about the teaching concept during naturalistic teaching contexts, wherein children’s communicative interactions were used as a gateway to their social understanding (Turnbull, Carpendale, & Racine, 2009). Participants included 39 sibling dyads (older age group, M_age = 6;4; younger age group, M_age = 4;5) observed for six 90-min sessions at home. Teaching episodes were identified and coded for: a) initiation of teaching (i.e., assumes role or learner requests teaching), b) knowledge states (i.e., knowledge, lack of knowledge, questioning knowledge), c) transfer of knowledge (i.e., learning), and d) teaching strategies (e.g., direct instruction). Children who assumed the teaching role referenced knowledge and questioning knowledge, whereas learners requested teaching by referencing a lack of knowledge. Firstborn learners were more likely to reference knowledge versus second-born learners who referenced a lack of knowledge. Transfer of knowledge occurred when teachers referenced knowledge. When learners referenced knowledge states, teachers were more likely to use direct instruction, demonstration, and negative feedback. Results underscore the developmental significance of sibling teaching and demonstrate a novel approach to studying children’s social understanding in the teaching context (Turnbull et al., 2009).
