The relationship between responsiveness to social and monetary rewards and ADHD symptoms

Alterations in reward processing are frequently reported in attention deficit hyperactivity disorder (ADHD). One important factor affecting reward processing is the quality of reward as social and monetary rewards are processed by different neural networks. However, the effect of reward type on reward processing in ADHD has not been extensively studied. Hence, in the current study, an exploratory research was conducted to investigate the effect of reward type (i.e., social or monetary) on different phases of reward processing. We recorded event-related potentials (ERPs) during a spatial attention paradigm in which cues heralded availability and type of the upcoming reward and feedbacks informed about the reward earned. Thirty-nine (19 males) healthy individuals (age range: 19-27 years) participated in the study. ADHD symptoms were assessed by using ADHD self-report scale (ASRS). Our results revealed a consistent negative correlation between the hyperactivity subscale of ASRS and almost all social-feedback related ERPs (P2, P3, and FRN). ERP amplitudes after social feedbacks were less positive for P2 and P3 and more negative for FRN for individuals with greater hyperactivity levels. Our findings suggest that hyporesponsiveness to social feedbacks may be associated with hyperactivity. However, the results have to be confirmed with clinical populations.     

The Soul,as an Uninhibited Mental Activity,is Reduced into Consciousness by Rules of Quantum Physics

This paper is an effort to describe, in neuroscientific terms, one of the most ambiguous concepts of the universe—the soul. Previous efforts to understand what the soul is and where it may exist have accepted the soul as a subjective and individual entity. We will make two additions to this view: (1) The soul is a result of uninhibited mental activity and lacks spatial and temporal information; (2) The soul is an undivided whole and, to become divided, the soul has to be reduced into unconscious and conscious mental events. This reduction process parallels the maturation of the frontal cortex and GABA becoming the main inhibitory neurotransmitter. As examples of uninhibited mental activity, we will discuss the perceptual differences of a newborn, individuals undergoing dissociation, and individuals induced by psychedelic drugs. Then, we will explain the similarities between the structure of the universe and the structure of the brain, and we propose that consideration of the rules of quantum physics is necessary to understand how the soul is reduced into consciousness.     

American women missionaries in the Gulf: Agents for cultural change

Arabia has figured in Western imagination from a very early time, but seldom in neutral terms. For reasons not thoroughly understood, the Arab role in Western thinking has fluctuated between hope and menace, love and hate. While nineteenth‐century Europe saw in Arabia a romantic adventure — an illustration of the Victorian era — nineteenth‐century America viewed it differently. It saw an alternation between the images of the supposedly fanatical Islam that at one time overran the Christian world and a deprived contemporary society in need of Christian aid. Plainly, Western images of Arabia have been more changeable than the conditions of Arab life. Perhaps one reason for this love/hate, menace/hope attitude lies in the fact that Islamic civilization has been the great alternative to Christendom. Being so different and also so distant, Arabia seemed like a cultural incognito, a place where Americans could start their intercultural experience. Nothing would bring them a step closer to their goal than missionary work.
