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.

Box for interaction with objects (BIO): A new device to synchronize the presentation of objects with electrophysiological recordings

Brain event-related potentials are a useful tool for investigating visual processing and action planning. This technique requires extremely accurate synchronization of stimulus delivery with recordings. The precision of the onset time of visual stimulus delivery is a major challenge when attempting to use real, three-dimensional objects as stimuli. Here, we present an innovative device, the “box for interaction with objects” (BIO), that is designed to synchronize the presentation of objects with electroencephalographic (EEG) recordings. To reach the required resolution of stimulus-onset timing, the BIO system features an interface with reflective glass and light-emitting diodes (LEDs). When the LEDs inside the BIO are turned on, the object inside becomes visible, and a synchronizing pulse is sent to the recording systems. The BIO was tested in a motivational study that focused on visual and motor event-related potentials. EEG signals were recorded during the presentation of an emotion-laden object that could be grasped and brought close to the participant’s chest. BIO successfully synchronized the appearance of a three-dimensional object with EEG recordings, which would allow for an analysis of visual and motor event-related potentials in the same experiment. The BIO device, through a high-quality psychophysiological approach, offers a new perspective for the study of the motivational factors that drive actions toward relevant stimuli.     

Moving through virtual reality without moving?

Virtual reality (VR) technology is increasingly used in spatial cognition research, as it offers high experimental control and interactivity in naturalistic multi-modal environments, something that is difficult to achieve in real-world settings. Even in the most sophisticated and costly VR systems, people do not necessarily perceive and behave as they would in the real world. This might be related to our inability to use embodied (and thus often highly automated and effective) spatial orientation processes in VR. While real-world locomotion affords automatic and obligatory spatial updating of our self-to-surrounding relationships, such that we easily remain oriented during simple perspective changes, the same is not necessarily true in VR. This can lead to striking systematic and qualitative errors such as failures to update rotations ("Nonturner" behavior). Here, we investigated whether rich naturalistic visual stimuli in immersive VR might be sufficient to compensate for the lack of physical motion. To this end, 24 participants performed point-to-origin tasks after visually simulated excursions along streets of varying curvature in a naturalistic virtual city. Most (21/24) participants properly updated simulated self-motions and showed only moderate regression toward mean pointing responses. 3/24 participants, however, exhibited striking "Nonturner" behavior in that they pointed as if they did not update the visually simulated turns and their heading had not changed. This suggests that our immersive naturalistic VR stimuli were an improvement over prior optic flow stimuli, but still insufficient in eliciting obligatory spatial updating that supported correct point-to-origin responses in all participants.     

Those Easily Forgotten: The Impact of Emigration on Those Left Behind

Much has been written about the experiences and stresses of those who emigrate. By contrast, little attention has been paid to the experiences of those who stay behind—family members and friends who for various reasons do not to join their loved ones in the destination country. In this article, I describe the experiences of some South Africans whose families and friends have emigrated. This study forms part of a larger research project focusing on the impact of emigration on South African family life. Twenty‐one participants were interviewed by means of a semistructured interview at least 6 months after one or more family member(s) and/or friend(s) left South Africa, to explore participants’ experiences around their loved ones’ emigration. A thematic analysis of the data reveals that those left behind experience various emotions, ranging from emotional ambivalence to anger and distress. Emigration is mostly experienced as a vast loss, almost akin to a “death,” bringing about significant changes in social networks and relationships. The therapeutic significance of the findings for those working with emigrant families is also explored.     

The Development of Family Alliance From Pregnancy to Toddlerhood and Child Outcomes at 5 Years

This article presents a longitudinal study of the development of “family alliance” from pregnancy to toddlerhood in a community sample, as well as its links with the emotional and cognitive development of the child at age 5 years. Family alliance is defined as the quality of the interactive coordination between family members. We consider that the alliance constitutes a context for the child to learn emotion regulation and to develop an understanding of inner states. Family interactions (N = 38) were observed at the 5th month of pregnancy and at 3, 9, and 18 months after birth in a standardized situation of observation (Lausanne Trilogue Play). Marital satisfaction and child temperament were assessed through self‐reported questionnaires. Several outcomes of the child at age 5 years were measured: theory of mind performances, predominant emotional themes in pretend play, internalized and externalized symptoms. Results show that (a) three patterns of evolution of family alliance occur: “high stable” (n = 19), “high to low” (n = 10), and “low stable” (n = 9); (b) a high stable alliance is predictive of better outcomes in children at age 5 years, especially regarding theory of mind; (c) the temperament of the child is predictive of child outcomes; and (d) an interaction effect occurs between family alliance and temperament. These results highlight the importance of both family‐level and individual‐level variables for understanding individual differences in the social and cognitive development of children.     

Belief in a just world and wellbeing in Indian schools

This study investigates the meaning of belief in just world (BJW) for students' subjective justice experiences with their parents and teachers and for students' subjective well-being. The hypotheses tested were that the more strongly students endorse BJW, the less the distress at school and depressive symptoms they experience. Two dimensions of BJW were assessed: personal BJW, reflecting the belief that events in one's own life are generally just, and general BJW, reflecting the belief that the world is basically a just place. The participants were 278 Indian students attending ten 10th grade classes at two private English-medium schools. The results showed that only the personal BJW, not the general BJW, was important in explaining justice experiences and wellbeing. The more the students endorsed the belief in personal just world, the more they felt treated justly by their teachers and their parents alike, and the less distress at school and depressive symptoms they experienced. In addition, teacher justice, but not parent justice, explained distress at school. Finally, the effect of personal BJW on depressive symptoms was partly mediated by both teacher and parent justice. This pattern of results persisted when class effects were controlled. Overall, this pattern of results emphasizes the importance of the individual and subjective experience of justice of the teacher behavior for adolescent wellbeing. Implications for further studies on BJW and wellbeing at school are discussed.
