BACKGROUND:When an action is being observed, it is matched to the observer’s internal representation of the action. The more similar, the more the action is perceived as natural. A factor influencing judgement of naturalness is the kinematic features of a movement. However, these features could be altered due to certain conditions that can modify movement such as Autism Spectrum Disorders. As a result, neurotypical observers may fail to interpret the action due to impaired naturalness.AIM:This work aims to investigate (1) whether neurotypical observers judge the autistic individuals’ movement as less natural, (2) which kinematic factors (jerk, acceleration, velocity and size) contribute to their perception and (3) whether cue reliance correlates with autistic traits.METHODS:Thirty neurotypical participants (20 – 33 years old; 15 males) completed autistic trait screening questionnaires (ADC, TAS-20, AQ). They completed a computer task showing 2D side-to-side arm movements recorded from neurotypical and autistic individuals. Finally, they rated the naturalness of the observed movements, and how certain they were with their answer.RESULTS:There was a significant difference between the participants’ perception of naturalness of the two movement groups. Jerk, acceleration and velocity contributed to shaping the participants’ perception with a jerk as the most significant factor. The correlation between the participants’ autistic trait and both their perception of naturalness as well as of each kinematic cue were not significant.CONCLUSION:Our neurotypical participants perceived the autistic movements as less natural. Their perceptions were influenced mainly by the jerk as well as acceleration and velocity of the autistic movements. Autistic traits in the participants did not correlate to their perception of movement naturalness nor to any of the kinematic factors.

The discovery of internet information, performed business transaction, etc. The occurence of social media since the 1990s has developed a new function of each other virtually. Unfortunately, social media is suspected to cause phubbing behavior among internet users. A previous study has stated that the 'like' and 'love' responses in social media posts may cause a social media addiction in the users' everyday life that can interfere with their daily activities. In this article, we explain briefly a review from neuroscience perspective on the emergence of addictive behavior in the use of social media in daily life.

Pornography content is becoming an increasingly serious problem in Indonesia, where it is suspected that around 97% of 1,600 children and adolescents have been exposed to pornography. Various efforts prevalence of pornography content, such as by blocking porn known that the exposure of massive and periodic pornography content to children and adolescents can result in adverse e EEG (Edison, RE., et al) and fMRI (Prawiroharjo, P., et al) have reported changes in the brain activity of children and adolescents who were suspected as having addiction to pornography content. Intere among the subjects. This article discusses the phenomenon from the perspectives of psychology and neuroscience.
