Healthy Lifestyle,Well-being,Physical Activity,Sport, and Scholastic/academic Performance: Interactions and Connections

The physical activity and sport are key elements for a healthy lifestyle. However, a little-investigated element is the presence of a possible relationship between school or academic performance and the participation in physical activity and sport in groups of preadolescents and adolescents. In order to clarify the complex relationship between mind and body in preadolescence and adolescence, the present discussion investigates the causal and direct relationship between sport activity and performance; and describes how this relationship can be mediated by the sense of self-esteem and self-efficacy; and investigates the relationship between group sports practice and school or academic performance.     

Internet Addiction Disorder: Internet Gaming Disorder in a Nonclinical Sample Of Moba And Mmorpg Videoplayers

This study concentrates on two kinds of video games, Massive Online Battle Arena and Massive Multiplayer Online Role Play Game, and examines the scores obtained by the subjects in the sample. Score analyses pointed out that they do not exceed the respective cutoff scores for each scale. The sample was divided into three clusters to differentiate three kinds of users: nonproblematic, problematic, and “addicted” players. The study highlights that the variable “video game typology” relates to some personality traits. Players who excessively use them tend to experience relatively more negative emotions (anxiety and depression), avoid socioemotional involvement, and report bizarre and culturally incongruent thoughts (accompanied by the respective behavioral displays).     

On the existence of category-specific impairments. A reply to Parkin and Stewart

Parkin and Stewart (this issue) criticize Sartori, Miozzo, and Job's (this issue) demonstration of a category-specific naming impairment for living things when sets of living and non-living things were matched for familiarity, visual complexity, name frequency, and visual similarity. In this paper we discuss the points raised by Parkin and Stewart and argue that they do not undermine our demonstration of a category-specific impairment.
