Cognitive functioning,personality variables and academic achievement of hemophilic and normal children: A comparative study

The present study was conceptualized in the context of the psychosocial needs of Hemophilic children and adolescents of Kolkata. Twenty four Hemophilic children and adolescents were compared with a matched group of normal controls to find out any specific difference in terms of visuomotor gestalt functioning, intellectual level, academic achievement and personality dimensions. Academic achievement was assessed by averaging the results of the last three consecutive school examinations. Intellectual functioning was assessed by Progressive Matrices by Raven, and personality dimensions were assessed by Junior Eysenck Personality Questionnaire. Chi square tests and ANOVA were conducted to determine whether the Hemophilic children differed significantly from the normal controls across age levels. Findings revealed that there was little difference between the two groups in terms of intellectual level, and most dimensions of personality, although the Hemophilics fared worse than normals in neuropsychological, social and academic aspects. Implication for intervention is discussed.     

Assessing the impact of organizational communication on job satisfaction and job performance

The present paper analyses the impact of organizational communication on job satisfaction and job performance. Data were collected from 380 employees working at different managerial levels in various organizations in India by using Organizational Communication Scale (Roberts & O’Reilly, 1974), Job Satisfaction Survey scale (Spector, 1985), and Job Performance scale (Rodwell, Kienzle & Shadur, 1998). It was found that organizational communication had a significant effect on job satisfaction and job performance of the employees. The analysis further indicated that the employees at different levels perceived job satisfaction differently. Thus, it can be inferred that in Indian organizations, job satisfaction and performance are very much dependent on the communication behavior of the organization.     

16 PF Profile of Schizophrenics With and Without Criminal Record

This study examined the personality characteristics of sixty Schizophrenics with and without criminal record on inpatients of Ranchi Institute of Neuro-Psychiatry and Allied Sciences, Ranchi (RINPAS) India. A comparison of their personality profiles on 16 PF test revealed that Schizophrenics with criminal record were more assertive, less reserved, less conscientious, and more extraverted than Schizophrenics without criminal record. It indicates that Schizophrenics who commit offences may be differentiated from those who are not involved in criminal act on the basis of their personality characteristics.     

Asparagus recemosus enhances memory and protects against amnesia in rodent models

Asparagus Racemosus (AR) is an Ayurvedic rasayana possessing multiple neuropharmacological activities. The adpatogenic and antidepressant activity of AR is well documented. The present study was undertaken to assess nootropic and anti-amnesic activities of MAR in rats. The Morris water maze (MWM) and elevated plus maze (EPM) models were employed to evaluate learning and memory activity. Subsequently, the anti-amnestic activity was evaluated in scopolamine and sodium nitrite (NaNO₂)-induced amnestic models in rats. Rats pre-treated with MAR (50, 100 and 200 mg/kg, p.o) for 7 days showed significant decrease in escape latency in the MWM test indicating nootropic activity. MAR also significantly reversed scopolamine and sodium nitrite-induced increase in transfer latency on EPM indicating anti-amnesic activity. Further, MAR dose-dependently inhibited acetylcholinesterase enzyme in specific brain regions (prefrontal cortex, hippocampus and hypothalamus). Thus, MAR showed nootropic and anti-amnesic activities in the models tested and these effects may probably be mediated through augmentation of cholinergic system due to its anti-cholinesterase activity.     

The role of idiosyncratic attribute evaluation in mass customization

The growing use of mass customization necessitates an understanding of consumers' evaluations of mass customization platforms. We hypothesize that consumers' objective and subjective knowledge of the customized product moderate the influence of idiosyncratically evaluated (i.e., personalizable) attributes on satisfaction with a customization platform. Consistent with our theoretical framework, results from three experiments show that offering greater variety in idiosyncratically evaluated attribute options increases consumers' satisfaction to a greater extent for: (1) novices than experts (2) consumers with more subjective knowledge, and (3) miscalibrated consumers whose subjective knowledge does not match their objective knowledge, than calibrated consumers whose subjective and objective knowledge match.     

Time course of visual attention across perceptual levels and objects

Theories of shifts of visual attention based on attentional blink or dwell time do not directly address shifts of attention across different levels (global or local) involving multiple objects. Two experiments were conducted employing the attentional dwell time paradigm to investigate the shifts of visual attention between objects selected at same or different levels. Participants were instructed to identify two successive compound stimuli at a pre-specified level (global or local) presented at two different locations with variable SOA. The initial pair of locations in which the stimulus was presented was fixed in Experiment 1 but not in Experiment 2. Experiment 1 results showed very little impairment for second target identification when both the targets were at the global level. Attentional shift was better with both targets at the same level compared to different levels. Experiment 2 results showed that local followed by global target identification is difficult at short SOAs compared to other conditions. The results indicate that scope of attention affects the time course of visual attention. Global processing could be performed with very little capacity limitation simultaneously with distributed attention. The default mode of attention might be distributed and attention becomes focused for target identification. Different mechanisms may underlie shifts in focused attention between different locations and changes in attentional set required by changes in perceptual levels.     

Screening detoxifying inpatients with substance-related disorders for a major depressive disorder

The Beck Depression Inventory-Fast Screen for Medical Settings (BDI-FS; [Beck, Steer, & Brown, 2000]) and the Mood Module (MM) from the Primary Care Evaluation of Mental Disorders [Spitzer, Williams, Kroenke, Linzer, deGruy, III, Hahn, & Brody, 1995] were used to screen 100 inpatients detoxifying from alcohol, illicit substances, or both for a major depressive disorder (MDD). Receiver operating characteristic (ROC) analyses indicated that both tests were highly and comparably effective in differentiating patients who were and not diagnosed with a MDD; the ROC areas-under-curves for the BDI-FS and MM were, respectively, .87 and .84. A BDI-FS cut-off score of 10 and above had 90% sensitivity and 78% specificity rates, and a MM cut-off score of 7 and above had 90% sensitivity and 72% specificity rates for discriminating patients with and without a MDD. The clinical advantages and disadvantages of both instruments for rapidly screening detoxifying inpatients for clinical depression were discussed.     

Income and neighbourhood‐level inequality predict self‐esteem and ethnic identity centrality through individual‐ and group‐based relative deprivation: A multilevel path analysis

Although income and inequality (objective measures of deprivation and the distribution of income within a defined area, respectively) predict people's self‐appraisals, the psychological mechanisms underlying these relationships are largely unknown. We address this oversight by predicting that feeling individually deprived (individual‐based relative deprivation [IRD])—a self‐focused appraisal—mediates the relationship between these two objective measures and self‐esteem. Conversely, believing that one's group is deprived (group‐based relative deprivation [GRD])—a group‐focused appraisal—mediates the relationship between these two objective measures and ethnic identity centrality. We examined these predictions in a national sample of New Zealand adults (N = 6349). As expected, income negatively correlated with IRD and GRD; in turn, IRD negatively correlated with self‐esteem, and GRD positively correlated with ethnic identity centrality. Moreover, after accounting for between‐level variability in income, neighbourhood‐level inequality had indirect effects on self‐esteem and ethnic identity centrality through IRD and GRD, respectively. Thus, income and inequality independently predicted self‐esteem and strength of ingroup identification through distinct mechanisms. Copyright © 2015 John Wiley & Sons, Ltd.     

Terminal decline of episodic memory and perceptual speed in a biracial population

We compared trajectories of terminal cognitive decline in older Black (n = 3372) and White (n = 1756) persons from a defined population who completed tests of episodic memory and perceptual speed at 3-year intervals for up to 18 years. During a mean of 9.9 years of observation, 1608 Black persons and 902 White persons died. Preterminal decline of episodic memory did not differ by race. Terminal episodic memory decline began earlier in Black persons (mean of 4.3 years before death) than in White persons (mean = 3.9 years) and progressed more slowly. By contrast, terminal decline of perceptual speed began earlier in White persons (mean = 5.0 years) than in Black persons (mean = 4.5 years). Rate of perceptual speed decline was more rapid in White persons than in Black persons in both the preterminal and terminal periods. The results indicate that terminal cognitive decline occurs in Black persons but suggest that the rate of cognitive decline during the terminal period is less rapid in Black persons than in White persons.     

Speech motor skill and stuttering

The authors review converging lines of evidence from behavioral, kinematic, and neuroimaging data that point to limitations in speech motor skills in people who stutter (PWS). From their review, they conclude that PWS differ from those who do not in terms of their ability to improve with practice and retain practiced changes in the long term, and that they are less efficient and less flexible in their adaptation to lower (motor) and higher (cognitive-linguistic) order requirements that impact on speech motor functions. These findings in general provide empirical support for the position that PWS may occupy the low end of the speech motor skill continuum as argued in the Speech Motor Skills approach (Van Lieshout, Hulstijn, & Peters, 2004).
