Dextroamphetamine and measures of intelligence

A sample of 320 male high school students was drawn on the basis of their neuroticism and extraversion scores from a population of 2500 students. By following a 4 × 4 randomized block design (replicated 20 times) an attempt was made to study the effects of dextroamphetamine on the test scores of fluid and crystallized intelligence of high school children. The study lends support to the hypothesis that the drug will have a differetial effect on the test scores of fluid and crystallized intelligence.     

Job stress and employee behaviors

The relationship between four job stresses (role ambiguity, role overload, underutilization of skills, and resource inadequacy) and two employee withdrawal behaviors (absenteeism and turnover) was investigated. The joint prediction of employee withdrawal from measures of job stress and selected backgroundd variables was also investigated. Data were obtained regarding 651 employees in five organizations through personal interviews and company records. Analysis indicated that job stress is related to employee withdrawal behaviors, that prediction of subsequent behaviors is stronger than prediction of prior behaviors, and that the predictive power of job stress and background variables taken together is as strong as, or stronger than, the predictive power of background variables alone. Confidence in the strength of the findings is enhanced by the use of multiple data sources and multiple data points.     

Vulnerability of facial attractiveness perception to early and multi-year visual deprivation

Judgments of facial attractiveness invariably accompany our perception of faces. Even neonates appear to be capable of making such judgments in a manner consistent with adults. This suggests that the processes supporting facial attractiveness require little, if any, visual experience to manifest. Here we investigate the resilience of these processes to several years of early-onset visual deprivation. Specifically, we study whether congenitally blind children treated several years after birth possess the ability to rate facial attractiveness in a manner congruent to normally sighted individuals. The data reveal significant individual variability in the way each newly sighted child perceives attractiveness. This is in marked contrast to data from normally sighted controls who exhibit strong across-subject agreement in facial attractiveness ratings. This variability may be attributable, in part, to atypical facial encoding strategies used by the newly sighted children. Overall, our results suggest that the development of facial attractiveness perception is likely to be vulnerable to early visual deprivation, pointing to the existence of a possible sensitive period early in the developmental trajectory.     

Practice makes perfect: familiarity of task determines success in solvable tasks for free-ranging dogs (<Emphasis Type="Italic">Canis lupus familiaris</Emphasis>)

Domestic dogs’ (Canis lupus familiaris) socio-cognitive faculties have made them highly sensitive to human social cues. While dogs often excel at understanding human communicative gestures, they perform comparatively poorly in problem-solving and physical reasoning tasks. This difference in their behaviour could be due to the lifestyle and intense socialization, where problem solving and physical cognition are less important than social cognition. Free-ranging dogs live in human-dominated environments, not under human supervision and are less socialized. Being scavengers, they often encounter challenges where problem solving is required in order to get access to food. We tested Indian street dogs in familiar and unfamiliar independent solvable tasks and quantified their persistence and dependence on a novel human experimenter, in addition to their success in solving a task. Our results indicate that free-ranging dogs succeeded and persisted more in the familiar task as compared to the unfamiliar one. They showed negligible amount of human dependence in the familiar task, but showed prolonged gazing and considerable begging behaviour to the human experimenter in the context of the unfamiliar task. Cognitive abilities of free-ranging dogs thus play a pivotal role in determining task-associated behaviours based on familiarity. In addition to that, these dogs inherently tend to socialize with and depend on humans, even if they are strangers. Our results also illustrate free-ranging dogs’ low competence at physical cognitive tasks.     

Structural examination of RIASEC scales in high school students: Variation across ethnicity and method

The structural validity of Holland’s model of vocational interests across racial/ethnic groups was examined in the population of high school juniors in two states. The fit of the circumplex model to Holland’s RIASEC types as assessed by the UNIACT-R was evaluated for the general sample and five subgroups: Caucasian/Euro-Americans, African Americans, Asian Americans, Latinos, and Native Americans. Four different methods were used to test the proposed circumplex structure, each with various circumplex definitions. Results indicate that nonparametric methods generally showed good model-data fit, whereas SEM-based results indicated less support. No differences in fit were found across ethnicity supporting the usage with U.S. ethnic groups.     

The effect of evolving resource synergy beliefs on the intentions–behavior discrepancy in ethical consumption

Consumers are less likely to buy ethical products than their stated intentions in marketplace polls, due at least in part to the distinct temporal frames guiding their poll responses versus actual purchase decisions. We propose that as consumers' beliefs about the synergy between the resources a firm devotes to their ethical and functional attributes evolve, as part of the broader ethical marketing/corporate social responsibility movement, from negative to positive, this discrepancy between intentions and behavior is likely to disappear. Two studies provide support for this basic contention, implicating the importance consumers ascribe to a brand's ethical attribute as the driver of the temporal frame- and resource synergy beliefs-based differences in their preference for that brand.     

The Engineering Undergraduate Experience: A Qualitative Perspective

College experience is central to the life of adolescents. Apart from academic tasks, identity development is an important feature of this developmental stage. This paper reports two studies. One study illustrates the qualitative aspects of the college experience. The second study investigates factors affecting the academic performance of undergraduate engineering students. Time management and its links with college experience and academic performance are explored in this paper. The formation of identity emerges as an overarching concept.     

Using Mixed Methods Approach in Cross-Cultural Studies: Lessons of a Research Experience

The primary purpose of this paper is to share the lessons the first author learnt as a novice researcher while carrying out a comparative culture study focused on exploring differences in organizational culture in units located in two societies in two distinct culture zones, using mixed methods approach, as a part of his doctoral research program. The authors have shared “why” and “how” the first author chose and applied mixed methods approach to conduct the above study, which might be of help to budding researchers, given that mixed methods approach is rarely used by doctoral students in India. The authors have presented three kinds of lessons in this paper, learnt by the first author. The first kind of lessons deals with the methodology, the second one is about the research approach and the last one is related to the qualities of an effective researcher. The authors have also presented “do’s and don’ts” in researching for the benefit of budding researchers. The insights shared in this paper, the authors hope, would be useful and relevant for the researchers employing mixed methods approach. Besides, it might also definitely help budding research scholars make an informed choice of research method to effectively deal with research problems under investigation.
