The Influence of Positive and Negative Affectivity on Attitude Change Toward Organizations

This study tests hypothesized differences in pre-post (product-harm) crisis attitude change toward an organization for positively and negatively oriented individuals. Contrary to theoretical predictions, there was not a strong differential attitude change between positively and negatively oriented individuals. The results suggest a possible boundary condition for the influence of positive and negative affectivity on attitude change. Two explanations are offered for these findings: (1) that the vividness of the situation might override affectivity and (2) that affectivity might not be a strong predictor of attitude change for nonpersonalized attitudes.     

刺激呈现时间对汉字语义加工脑偏侧化的影响

以往关于汉字字词识别脑功能偏侧化的研究发现了左半球优势、右半球优势或者大脑两半球均势三种不同的结果。该研究采用一侧化Stroop范式(刺激分别只呈现于左视野、中央视野或右视野中),通过系统地改变刺激呈现时间以期探讨刺激呈现时间是可以解释这些不一致结果的可能因素之一。结果显示:对于右利手被试,在刺激呈现时间为60 ms时右半球出现了较强的Stroop效应,在刺激呈现200 ms时左右半球的Stroop效应没有表现出差异,在刺激呈现时间较长时左半球表现出较强的Stroop效应。该结果提示,随着刺激呈现时间的延长,语义优势发生了从右半球到左半球的转换。     

Social anxiety disorder in childhood and adolescence: descriptive psychopathology

Although the presentation of social anxiety disorder (SAD) in adults is well documented, less is known about its clinical manifestation in children and adolescents. To date, most studies have included combined samples of children and adolescents despite the fact that this age range represents an extensive period of growth and development. This study compares and contrasts the clinical presentation of SAD among children (ages 7-12) and adolescents (ages 13-17). One hundred and fifty children (n=74) and adolescents (n=76) with a primary diagnosis of SAD participated in the study. The assessment battery included clinical ratings and behavioral observation as well as parental and self-report. The results indicate that, although the symptom presentation of children and adolescents with primary SAD shares many features, children tend to present with a broader pattern of general psychopathology, while adolescents have a more pervasive pattern of social dysfunction and may be more functionally impaired as a result of their disorder. These findings suggest that interventions for SAD need to carefully consider clinical presentation of the disorder as it manifests in childhood and adolescence.     

Perspectives of Indian Traditional and Allopathic Professionals on Religion/Spirituality and its Role in Medicine: Basis for Developing an Integrative Medicine Program

Allopathic medical professionals in developed nations have started to collaborate with traditional, complementary, and alternative medicine (TCAM) to enquire on the role of religion/spirituality (r/s) in patient care. There is scant evidence of such movement in the Indian medical community. We aim to understand the perspectives of Indian TCAM and allopathic professionals on the influence of r/s in health. Using RSMPP (Religion, Spirituality and Medicine, Physician Perspectives) questionnaire, a cross-sectional survey was conducted at seven (five TCAM and two allopathic) pre-selected tertiary care medical institutes in India. Findings of TCAM and allopathic groups were compared. Majority in both groups (75 % of TCAM and 84.6 % of allopathic practitioners) believed that patients’ spiritual focus increases with illness. Up to 58 % of TCAM and allopathic respondents report patients receiving support from their religious communities; 87 % of TCAM and 73 % of allopaths believed spiritual healing to be beneficial and complementary to allopathic medical care. Only 11 % of allopaths, as against 40 % of TCAM, had reportedly received ‘formal’ training in r/s. Both TCAM (81.8 %) and allopathic (63.7 %) professionals agree that spirituality as an academic subject merits inclusion in health education programs (p = 0.0003). Inclusion of spirituality in the health care system is a need for Indian medical professionals as well as their patients, and it could form the basis for integrating TCAM and allopathic medical systems in India.     

Psychology in Indian Tradition

In the Indian tradition, psychology is the study of the person (jiva). The person is a composite of consciousness, mind and body, a unique blend of thought, passion and action. Consciousness is perceived as changeless and the permanent base of all knowledge and awareness. Mind is the interfacing instrumentality, a necessary link between consciousness and the body. The body is the physical base, and the frame that constrains and moulds consciousness reflected in the mind of the person. The person, in the existential condition, is seen as conditioned, her consciousness is clouded and consequently unable to know the truth and realize her full potential. This is considered to be a state of ignorance and suffering that needs to be overcome. The goal of Indian Psychology is to understand the human condition and to explore ways to elevate it to higher levels of being, to clear the clouds of ignorance, and to enable the person to attain a state of bliss where the truth is known and the person becomes perfect. Three ways of achieving such a state are suggested: work (karma marga), worship (bhakti marga), and wisdom (jnana marga), which appear to cater to the three basic aspects of the mind: volition, emotion and cognition. In essence, each of these is a distinct way of deconstructing the ego, which is believed to be the main obstacle to transcending existential limitations. The applications of IP include (1) holistic understanding of human nature, (2) exploring the extended spectrum of the human condition, (3) exploiting the hidden potentials for the common good, and (4) cultivating altruism in the person and conflict-free conditions in society.     

Reducing self‐control depletion effects through enhanced sensitivity to implementation: Evidence from fMRI and behavioral studies

Research suggests self-control relies on a limited set of resources that can be diminished by use. Recent theories posit that there are two stages of self-control: recognizing the need for control and implementing controlled responses. We conducted a functional magnetic resonance imaging experiment and an intervention experiment to investigate whether one or both stages were affected by the prior exercise of self-control. Results from both experiments indicated that only the implementation stage was affected. Further, we demonstrate that self-control can be increased by an intervention designed to boost implementation, as opposed to the recognition of the need to control one's responses.     

Social deviance activates the brain’s error-monitoring system

Social psychologists have long noted the tendency for human behavior to conform to social group norms. This study examined whether feedback indicating that participants had deviated from group norms would elicit a neural signal previously shown to be elicited by errors and monetary losses. While electroencephalograms were recorded, participants (N = 30) rated the attractiveness of 120 faces and received feedback giving the purported average rating made by a group of peers. The feedback was manipulated so that group ratings either were the same as a participant’s rating or deviated by 1, 2, or 3 points. Feedback indicating deviance from the group norm elicited a feedback-related negativity, a brainwave signal known to be elicited by objective performance errors and losses. The results imply that the brain treats deviance from social norms as an error.     

One-step synthesis of bulk quantities of graphene from graphite by femtosecond laser ablation under ambient conditions

Bulk synthesis of few-layer graphene (FLG) for industrial applications still remains a challenge for researchers. Here, we report a very simple technique for bulk synthesis of FLG by femtosecond laser ablation of graphite powder suspended in ethanol without the requirement of a controlled environment. Graphite powder, with an average particle size <20 μm, was suspended uniformly in ethanol and ablated at room temperature using fs pulses (wavelength ~800 nm and an input beam diameter ~8 mm) followed by ultrasonication to obtain FLG with a lateral size of ~1 μm. Raman spectroscopy and high-resolution transmission electron microscopy data confirmed the nature and morphology of the FLG. The quality and number of layers in the FLG could be controlled by tuning the laser parameters.     

Role of Body Dissatisfaction in Developmental Psychopathology Among the Adolescents with Obesity: A Matched Case Control Study

Body-image is a significant component of self-image, and problems with the same are associated with several behavioural and psychological disorders. Adolescents, who otherwise more concerned about their body-image than any other age group, are at a higher risk for various psychological problems due to obesity. But much of our understanding in this regard comes from studies on the adults. In this backdrop, this study aims to examine the role of body dissatisfaction in developmental psychopathology among adolescents with obesity. Participants were 32 adolescents with obesity and 32 with normal weight, aged 11–16 years and school-going. Both groups were matched for age, gender and academic levels on one-to-one basis. Those with a body mass index (BMI) ≥ 30 kg/m² were considered obese, and those with a BMI < 25 kg/m² were considered as normal weight. All the participants were assessed using standard scales of body-image and developmental psychopathology. Results indicated that both obesity and poor body-image correlated with psychopathology in specific domains, but neither of them predicted psychopathology. This study suggests that body-image and obesity are risk factors but not predictors of psychopathology. However, psychosocial interventions are indicated to address the issues of body satisfaction and self-image in adolescents with obesity.
