Effects of plant growth retardant daminozide (Alar) on neuromuscular co-ordination behavior in Drosophila melanogaster.

Daminozide (alar), a plant growth retardant, is used in different fruit orchard to make fruits attractive and reduce pre-harvest losses. Previously data demonstrated that acute daminozide exposure affected reproductive fitness and produced neurodegeneration in Drosophila melanogaster. The goal of this study was to determine whether continuous exposure to daminozide affects neuromuscular co-ordination in D. melanogaster as manifested in various behavioral responses. Fruit flies were exposed to 200 or 400 mg/L concentration of daminozide for two successive generations. Treated D. melanogaster were examined for the behaviors indicative of neuromuscular coordination and cognitive abilities, that include climbing, social interaction, adult grooming, migration, flight, male aggression, and adult courtship. Aberrant behavioral responses were noted among treated D. melanogaster of both sexes as evidenced by the following parameters: reduction in flight duration, abnormal social interaction, altered copulatory acts, and over-aggressiveness. Data suggest that daminozide produces impairment in neuromuscular coordination and cognitive ability in Drosophila, which was reflected as altered behavioral patterns. As Drosophila is considered as a reliable in vivo model utilized in toxicity testing, our findings may help us to anticipate and monitor potential daminozide-induced toxicity in animals and humans.

Compreensão de emoções, aceitação social e avaliação de atributos comportamentais em crianças escolares / Emotion understanding, social acceptance and evaluation of behavioral attributes in school-age children

Diversos pesquisadores do campo de estudos sobre teoria da mente têm investigado a relação entre compreensão de emoções e interação social. Seguindo essa linha de investigação, o presente estudo explorou a relação entre compreensão emocional, aceitação social e avaliação de atributos comportamentais pelos pares. Cinquenta e duas crianças escolares responderam a um teste de inteligência emocional e a dois testes de avaliação sociométrica. Não foi encontrada uma correlação entre a compreensão emocional e a aceitação social, porém uma correlação negativa entre a compreensão emocional e a avaliação de atributos ligados à agressividade/disruptividade foi observada. Esses resultados sugerem que o conhecimento de diferentes emoções e de estratégias de regulação emocional podem tornar as crianças menos propensas à agressividade reativa.

Several researchers in the theory of mind field have been investigating the relation between emotion understanding and social interaction. Following this line of investigation, the present study explored the relation between emotion understanding, social acceptance and evaluation of behavioral attributes by peers. Fifty-two school-aged children were administered an emotional intelligence test and two instruments of sociometric evaluation. A correlation between emotion understanding and social acceptance was not found, however, a negative correlation between emotion understanding and the evaluation of behavioral attributes related to aggressiveness/disruptivity was observed. The results suggest that the knowledge of different emotions and of emotion regulation strategies may make children less prone to reactive aggressiveness.
