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.     

High-efficiency single-layer organic light-emitting diode based on green fluorescent protein

We have fabricated a molecular organic light-emitting device comprising indium–tin oxide/a molecular organic layer/aluminum in which the organic layer is a green fluorescent protein. The device exhibits peak external quantum and power efficiencies of 8?±?0.2% and 13?±?0.7?lm?W?^??1 at a current of J?=?1.5?A?m^?2, respectively. In addition, the turn-on voltage is 2.5?V for 1?cd?m^?2 and the maximum luminance achieved is 1275?cd?m^?2. This good performance can be explained by the presence of singlet-excited states, leading to a high internal efficiency.     

Relations of attachment styles and group cohesion in premier league female volleyball players

The relations of attachment styles with group cohesion were monitored for premier league female volleyball teams. 74 volleyball players from 8 teams responded to the Relationship Scales Questionnaire and Group Environment Questionnaire. Pearson correlations indicated significant association of attachment styles with group cohesion. Specifically, a significant negative correlation was found between female volleyball players' individual attraction to the group-social subscale and fearful attachment style. In addition, there was a significant positive correlation for scores on the group integration-social and secure and preoccupied attachment subscales and a significant negative correlation for scores on the group integration-task subscale and preoccupied attachment style. In conclusion, attachment styles might be considered important in predicting group cohesion     

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.     

Religiousness,spirituality, and eudaimonic and hedonic well-being

This study tested a conceptual model of religiousness/spirituality (R/S) and hedonic well-being (HWB; measured by life satisfaction and positive affect) by including eudaimonic well-being (EWB; measured by meaning in life) as a mediator. Given the multidimensionality of R/S, we examined whether and how the magnitudes of direct and indirect relationships varied for various aspects of R/S: organizational religious practices, private religious practices, daily religious/spiritual experiences, and subjective spirituality. Web survey data of 450 US American adults were analyzed using structural equation modeling. Results showed that EWB partially mediated the relation of daily religious/spiritual experiences and HWB; however, the other three aspects of R/S had no indirect relationships with HWB. Additionally, private religious practices and subjective spirituality indicated negative direct relationships with HWB. Approximately 68% of the variance in HWB was accounted for by the variables included in this model. Implications for research and clinical practice are discussed.     

Neuroticism and Close Relationships: How Negative Affect is Linked with Relationship Disaffection in Couples

Dispositional vulnerability afforded by personality can lead to adverse relationship outcomes. Neuroticism personality is bundled with a disadvantageous temperament that makes people high in neuroticism more sensitive to negativity. Consequently, neuroticism signifies negative emotions such as anger, anxiety, and sadness. Neuroticism is also inversely related to marital satisfaction. The present study examined the relationship between relationship disaffection (emotional indifference) and negative affect in the context of neuroticism. The present study included 819 participants (511 females, 308 males) between the ages of 18 years to 74 years (M = 27.16, SD = 10.58) who were in a committed or married heterosexual relationship. Our mediation model explored the relationship between neuroticism and relationship disaffection with negative affect acting as a mediator. We found a modest indirect relationship between neuroticism and relationship disaffection via negative affect. Acknowledging that individuals high in neuroticism are temperamentally sensitive to negative stimuli, therapists can assist partners in learning ways to curb negative mood to combat relationship disaffection. Future studies can build on these findings and design research addressing the limitation of the present study.
