Pramipexole: augmentation in the treatment of depressive symptoms

We describe a retrospective case series of three patients, two with bipolar depression and one with unipolar depression. Pramipexole is a Food and Drug Administration-approved antiparkinsonian agent, which, when used to augment antidepressants, would be considered an off-label use and should be discussed with the patient. These patients had robust responses to pramipexole augmentation of their treatment regimen. All three patients had been taking an atypical antipsychotic. The depressive symptoms were evaluated using the Hamilton Rating Scale for Depression.     

Simple visual reaction time,personality and strength of the nervous system: A signal-detection theory approach

Eysenck (1967) has reviewed evidence which suggests that introverts have a higher level of arousal than extraverts. Moreover, Gray (1967) has proposed that introverts have weak nervous systems, in the Russian terminology. Studies of simple reaction time such as that of Mangan and Farmer (1967) have posed problems for these views, but it is suggested that this may have been due to criterion differences between introverts and extraverts. In the present study a simple visual reaction-time task and a signal-detection task were conducted side by side. No significant differences between introverts and extraverts were found in measures of strength derived from the former, or measures of criterion derived from the latter. However, high N Ss were found to have a significantly lower value for Nebylitsyn's index of the slope of the reaction time/stimulus intensity function, thus supporting the view that high N Ss have relatively weak nervous systems.     

Point biserial correlation coefficient and its generalization

The problem of measuring the association between two characters, one quantitative and the other qualitative, is discussed. The formula for the large sample standard error of the point biserial correlation coefficient under general conditions is derived. The point multiserial correlation coefficient is introduced and some of its properties are examined. Tests of different hypotheses appropriate to these types of problems are formulated.I wish to pay my sincerest thanks to Dr. C. R. Rao, Dr. S. K. Mitra, and the reviewers for their valuable suggestions.     

Effect of schizotypy on responding maintained by free-operant schedules of reinforcement

Deviations from otherwise reliable patterns of responding in human performance on schedules of reinforcement could be associated with personality characteristics, such as psychometrically-measured schizotypy. The present study examined differences between high and low scorers on four schizotypy subscales (unusual experiences, cognitive disorganisation, introvertive anhedonia and impulsive non-conformity) on a random-ratio (RR) and random-interval (RI) schedule of reinforcement. Results showed a higher rate of responding on the RR than RI schedule, consistent with the differences in performance normally observed between these schedules. However, these differences were dependant on whether or not participants scored high or low on the schizotypy subscales, as well as the specific schedule parameters between the schedules. Specifically, high scorers on the unusual experiences (UE) subscale of the O-LIFE(B) were the only group in Experiment 1 not to show a difference in schedule performance, suggesting high scores on this subscale are linked to altered RR and RI performance. Experiment 2 explored this finding further using different schedule parameters, and confirmed that high scorers in UE did not differ in response rates between the two schedules.     

Internalized Misogyny as a Moderator of the Link between Sexist Events and Women’s Psychological Distress

This study examined the relationship between internalized misogyny and two other forms of internalized sexism, self-objectification and passive acceptance of traditional gender roles. In addition, it examined the moderating role of internalized misogyny in the link between sexist events and psychological distress. Participants consisted of 274 heterosexual women who were recruited at a large southern university in the United States and completed an online survey. Results indicated that internalized misogyny was related to, but conceptually distinct from self-objectification and passive acceptance. Findings also indicated that greater experiences of sexist events were associated with higher levels of psychological distress. In addition, internalized misogyny intensified the relationship between external sexism and psychological distress.     

Neuromarketing in predicting voting behavior: A case of National elections in India

Political choice has huge importance, either expressed in the balloting place or in the exit poll, in bringing a political party to power and thus impacting the economy and society's welfare. Research in leadership and decision-making suggests that the physical characteristics and traits of an individual influence the consumer's trustworthiness. Despite being a less explored research area, studying the impact of specific verbal and non-verbal cues of a political leader through a technological lens, such as eye-tracking has been sparsely talked about. Three sets of experiments were conducted to study voters' visual attention and reactions to gage their willingness to vote. First, an eye-tracking tool was used to record the visual attention and regions of interest (ROI) of voters. Subsequently, a short survey was used to analyze the “willingness to vote”, followed by a pilot study on their attention to non-verbal cues from the candidate. Also, a sentiment analysis of the voters was gathered from social media platforms. The present study analyzed the non-verbal aspects of a political leader with regard to voting intention and found that even a few of the non-verbal cues have an influence on the willingness to vote for a candidate. The findings contribute to the literature of neuro-politics and decision-making by analyzing voters' experiences of two political leaders, Narendra Modi (NaMo) and Rahul Gandhi (RaGa) based on non-verbal cues. Political parties and candidates should focus on non-verbal cues to increase their chances of winning elections. In addition, practitioners from the industry should incorporate appropriate non-verbal cues while designing ad campaigns, personal branding, PR campaigns, and CEO addresses.     

Couples treatment for major depression: critique of the literature and suggestions for some different directions

Current couples approaches to the treatment of depression show considerable promise for some couples, but have substantial room for improvement – in terms of efficacy as well as applicability and acceptability to a broader population. Although conjoint approaches have been shown to be efficacious in reducing couple distress and are possibly efficacious in ameliorating depression that co-occurs with couple distress, methodological problems hamper generalization from the published findings. Therefore, it is not clear that most depressed persons are likely to benefit from currently available conjoint formats. Most basically, there may often be obstacles that prevent or delay partner involvement, highlighting the need for treatments that can enhance relationship functioning without relying on a conjoint format. Existing treatment delivery systems may also fail to reach a considerable segment of the population. Developing a more flexible set of options for implementing couple-focused treatment, as well as rethinking dominant assumptions about depression, may be integral to extending the viability of couples therapy for depression.
