Integrating sequential arrays in visual short-term memory

Are sequential visual arrays represented as separate images or as a combined image in visual short-term memory (VSTM)? Proponents of the integration account suggest that an image of the first array is gradually formed and integrated with an image of the second to produce a combined representation. This view is evidenced by successful performance in an empty-cell detection task. In this task, on a 4 x 4 square matrix, 7 locations are occupied on a first array, followed by a variable interval, and then by 8 other occupied locations on a second array. Subjects' success in identifying the remaining empty cell has been taken as evidence for integration. In this study, we show that success in this task can be better accounted for by a convert-and-compare process than by an integration process. We conclude that VSTM only supports limited integration across sequential arrays.     

Individual Differences in Substance Preference and Substance Use

Using H. J. Eysenck's (1957, 1967) theory of temperament, this study examined the relationship between drug preference, drug use, and personality among incarcerated inmates. Analysis indicated a general preference for marijuana and alcohol over 8 other commonly used drugs across different personality types. Theoretical and clinical implications are offered.     

Examining role stress among technical students in India

Although organizational stress has been the subject of much research, role stress among professional students in India has not been well examined. This study explores the extent and types of role stresses present among the engineering and management students in India. The findings reveal that students are experiencing role overload, role stagnation and self-role distance. Male students experience higher levels of role stagnation than female students. However, no significant differences could be observed on any of the role stressors between first year students and their seniors, or between management and engineering students. The results are indicative of the social and educational environment prevailing in the country.     

Correlates of Canadian native children's reading performance: From cognitive styles to cognitive processes

Individual differences in reading and cognitive processing among a sample of generally poor readers were studied in order to answer two major questions: Do they have a specific cognitive style that favors global-simultaneous strategies and a weak sequential strategy? If they do not have a distinct cognitive style or strategy, but are merely poor in using sequential (Successive) strategies, then, would the same processes that influence reading performance in the general population determine their performance as well? A sample of 84 Canadian First Nations (FN) children were assessed in word and pseudoword reading, rapid naming speed, and ability to process information using the Planning, Attention, Successive, and Simultaneous (PASS) theory of intelligence. Results confirmed that this sample of children did not exhibit a specific cognitive style. Rather, there was evidence of a weakness in Successive processing only in the subgroup of poor readers. The importance of understanding the role of Successive processing and rapid naming speed relative to reading is further discussed.     

Suicidal behavior in hospitalized schizophrenics

A group of 131 hospitalized schizophrenics who had attempted suicide within the past year was compared with another group of 70 hospitalized schizophrenics who had not attempted suicide, using the Present State Examination (PSE) depressive symptoms. The former had a significantly higher number of symptoms indicative of a depressive disorder.     

Initial Development and Validation of a Measure of Intercultural Development Scale

Intercultural development in global employees will aid organizations to function successfully in the current global work scene. However, there is a need for a psychometrically valid and reliable measure, which can be used by practitioners and academics to assess the capabilities of individuals. This vignette based intercultural development scale was conceived on the basis of Bennett’s developmental model of intercultural sensitivity. The content was generated using interviews with international employees and subject matter experts. Psychometric properties were established with both qualitative and quantitative analysis. A sample of 461 international employees was used to test the validity of the scale. Confirmatory factor analysis, reliability analysis and construct validity was established with cosmopolitanism and openness to experience scales. The study confirms the scale’s dimensionality and established convergent, discriminant and nomological validity. The applications of this scale in building capabilities, talent management and strategic decisions in both practical and theoretical assessment are outlined.     

Positive Psychology and Indian Psychology: Birds of the Same Feather

Positive psychology and Indian psychology share similar concerns regarding human life. But Indian psychology has more to offer towards our understanding of happiness and well-being than what Positive psychology can at this point of time, because of latter’s paradigmatic limitations. This commentary draws attention to certain shortcomings of the target article: (a) in presenting the contemporary Positive psychology perspective; (b) in conceptualizing IP with reference to its epistemological position; (c) and in equating certain concepts from PP and IP and their implications.
