Social facilitation of laughter and smiles in Preschool children

Surprisingly little is known about the social dimensions of laughter in preschool children. We studied children's responses to amusing video clips in the presence or absence of peers. The sample consisted of 9 boys and 11 girls aged 31-49 months (M 39.8, SD 4.2) who watched three cartoons under three different conditions: individually, in pairs, or in groups of 6 or 8. The social viewing conditions showed significantly higher numbers of laughs and smiles than the individual viewing condition. On average children laughed eight times as much in company as on their own and smiled almost three times as much. No differences were found between pairs and groups, and no association was found between subjective funniness ratings and group size. This suggests that the presence of even a single social partner can change behavior in response to humorous material. It supports the idea that laughter and smiles are primarily flexible social signals rather than reflexive responses to humor

Eight-month-old infants’ behavioural responses to peers’ emotions as related to the asymmetric frontal cortex activity

Infants are sensitive to and converge emotionally with peers’ distress. It is unclear whether these responses extend to positive affect and whether observing peer emotions motivates infants’ behaviors. This study investigates 8-month-olds’ asymmetric frontal EEG during peers’ cry and laughter, and its relation to approach and withdrawal behaviors. Participants observed videos of infant crying or laughing during two separate sessions. Frontal EEG alpha power was recorded during the first, while infants’ behaviors and emotional expressions were recorded during the second session. Facial and vocal expressions of affect suggest that infants converge emotionally with their peers’ distress, and, to a certain extent, with their happiness. At group level, the crying peer elicited right lateralized frontal activity. However, those infants with reduced right and increased left frontal activity in this situation, were more likely to approach their peer. Overall, 8-month-olds did not show asymmetric frontal activity in response to peer laughter. But, those infants who tended to look longer at their happy peer were more likely to respond with left lateralized frontal activity. The link between variations in left frontal activity and simple approach behaviors indicates the presence of a motivational dimension to infants’ responses to distressed peers

New corporate identity of Studio S

Due to the rapid changes in the marketing environment, organizations find themselves in an outdated philosophy, vision and mission of the company. New work areas, changing or upgrading services may give a rise for a new corporate image. At that time new questions begins, which we have to answer thoughtfuly. The designer is facing a major challenge, since the formation of its new corporate identity depends on the success of the company and the response of the target audience. I will present the theoretical foundations, which are an important element of corporate identity. I analyzed the original graphic sign of the Studio S, which I transformed into a timeless and modern logo. In the practical part I will present a modern logo of that company. Renewed logo will present several applications, which are important for the presentation of the company. The successful preparation of learning will encourage students to think about the good qualities of the logo. The empirical part I will carried out in primary school and analyse their work
