Ethical Academic Judgments and Behaviors: Applying a Multidimensional Ethics Scale to Measure the Ethical Academic Behavior of Graduate Students

Using Reidenbach and Robin's Multidimensional Ethics Scale, this study investigated the relationships between background variables and students' ethical evaluations, judgments, and behavioral intentions using 3 scenarios involving dilemmas related to academic dishonesty. The sample included 436 master's students and 142 doctoral students. The study found that the participants used a combination of ethical philosophies to make ethical decisions. The respondents judged improper citations more harshly than acts of inappropriate authorship or the falsification of data. The doctoral students generally considered behaviors related to plagiarism and falsification to be more unethical than the master's students did, though no gender differences were found.     

The topology of performance curves during 72 hours of sleep loss: A memory and search task

Three levels of working memory load of a visual search (Memory and Search) task were tested in a 72-hour sleep deprivation paradigm. General performance and accuracy decrease over time with monotonic and rhythmic components. The signal detection discriminability index, d', decreases monotonically with rhythmic variations. The index of response bias, β, shows no monotonic trend, but significant circadian rhythmicity. The extent of the monotonic and rhythmic changes in accuracy and in d' is directly related to the level of working memory load. The amplitude of the circadian component of accuracy and d' is enhanced for the higher levels of working memory load. The implication of potentiated circadian rhythmicity as a function of cumulative sleep loss is discussed.     

The Relative Importance of Personality,Financial Satisfaction,and Autonomy for Different Subjective Well-Being Facets

Abstract

Using a nationally representative sample (N?=?507) from Singapore, this study examined whether personality, financial satisfaction, and autonomy were important to subjective well-being (SWB), and how the importance of these predictors varied across different SWB facets—life satisfaction, happiness, positive feelings, and negative feelings. The findings indicated that neuroticism, financial satisfaction, and autonomy, were important predictors of happiness. Personality was most important for affective well-being (i.e., positive and negative feelings), whereas financial satisfaction was most important for life satisfaction. Specifically, neuroticism accounted for substantial variance in positive and negative feelings, and was the strongest correlate among the Big Five traits. In contrast, financial satisfaction explained most of the variance in life satisfaction. This highlights that the importance of well-being predictors depended on the facet of well-being examined. The findings suggest that residents in an affluent nation like Singapore do not emphasize only postmaterialist values (e.g., autonomy) and disregard materialist concerns (e.g., financial satisfaction). Though certain SWB facets (positive and negative affect) are largely influenced by dispositional factors, other facets (life satisfaction and happiness) are closely related to factors (e.g., financial satisfaction, autonomy) that may be affected by social policies. Policymakers can thus target those aspects to enhance people’s SWB.     

Improving insight and non‐insight problem solving with brief interventions

Developing brief training interventions that benefit different forms of problem solving is challenging. In earlier research, Chrysikou (2006) showed that engaging in a task requiring generation of alternative uses of common objects improved subsequent insight problem solving. These benefits were attributed to a form of implicit transfer of processing involving enhanced construction of impromptu, on‐the‐spot or ‘ad hoc’ goal‐directed categorizations of the problem elements. Following this, it is predicted that the alternative uses exercise should benefit abilities that govern goal‐directed behaviour, such as fluid intelligence and executive functions. Similarly, an indirect intervention – self‐affirmation (SA) – that has been shown to enhance cognitive and executive performance after self‐regulation challenge and when under stereotype threat, may also increase adaptive goal‐directed thinking and likewise should bolster problem‐solving performance. In Experiment 1, brief single‐session interventions, involving either alternative uses generation or SA, significantly enhanced both subsequent insight and visual–spatial fluid reasoning problem solving. In Experiment 2, we replicated the finding of benefits of both alternative uses generation and SA on subsequent insight problem‐solving performance, and demonstrated that the underlying mechanism likely involves improved executive functioning. Even brief cognitive– and social–psychological interventions may substantially bolster different types of problem solving and may exert largely similar facilitatory effects on goal‐directed behaviours.     

Is STEM running out of steam for Asian Americans? College admissions officers' perceptions of applicants

While many people view Asian Americans as ‘model minorities’ who excel in math, science and music, they are also negatively stereotyped as nerdy and unsociable. Research has shown that Asian Americans have to outperform other races academically to receive equal consideration by colleges. This study is the first to test whether this bias is directed towards all Asian Americans or only those who fit the model minority stereotype. The present experiment investigates the effect of race and stereotypes on perceptions of students in the college admission process. College admission officers (N = 79) were randomly assigned to view a shortened version of a college application. The participants rated the student whose application they saw according to likelihood of being accepted into college, social competence, academic competence and contribution to a college's diversity. The stereotypical Asian American student was perceived to be significantly less likely to be accepted into college and had a lower perceived social competence than the other three students. Additionally, students who participated in counter‐stereotypical Asian activities were perceived as being more likely to be accepted, more socially competent and to contribute more diversity than students who participated in stereotypical Asian activities. A multiple regression revealed that social competence was the only significant predictor of likely acceptance. This study suggests that rather than all Asian American students being disadvantaged in the college admissions process, it is only those who fit common stereotypes who are affected.     

Development of a mentoring program for Chinese immigrant adolescents' cultural adjustment

The development and evaluation of a peer mentoring program for Chinese immigrant adolescents' cultural adjustment is described. Twenty-three high school students who recently immigrated from Mainland China participated in the year-long program and 4 high school students served as their peer mentors. Data analyses revealed that the students who participated in the mentoring program had significantly higher peer attachment-trust and need for closeness scores at post-test than at pre-test. Implications for working with adolescent immigrants are discussed.     

Perceived cultural importance and actual self-importance of values in cultural identification

Cross-cultural psychologists assume that core cultural values define to a large extent what a culture is. Typically, core values are identified through an actual self-importance approach, in which core values are those that members of the culture as a group strongly endorse. In this article, the authors propose a perceived cultural importance approach to identifying core values, in which core values are values that members of the culture as a group generally believe to be important in the culture. In 5 studies, the authors examine the utility of the perceived cultural importance approach. Results consistently showed that, compared with values of high actual self-importance, values of high perceived cultural importance play a more important role in cultural identification. These findings have important implications for conceptualizing and measuring cultures.     

Effect of chronic angiotensin converting enzyme inhibition on spatial memory and anxiety-like behaviours in rats

Angiotensin converting enzyme inhibitors (ACEis) are widely used anti-hypertensive agents that are also reported to have positive effects on mood and cognition. The present study examined the influence of the ACEi, perindopril, on cognitive performance and anxiety measures in rats. Two groups of rats were treated orally for one week with the ACEi, perindopril, at doses of 0.1 and 1.0mg/kg/day. Learning was assessed by the reference memory task in the water maze, comparing treated to control rats. Over five training days both perindopril-treated groups learnt the location of the submerged platform in the water maze task significantly faster than control rats. A 60s probe trial on day 6 showed that the 1.0mg/kg/day group spent significantly longer time in the training quadrant than control rats. This improved performance in the swim maze task was not due to the effect of perindopril on motor activity or the anxiety levels of the rats as perindopril-treated and control animals behaved similarly in activity boxes and on the elevated+maze. These results confirm the anecdotal human studies that ACEis have a positive influence on cognition and provide possibilities for ACEis to be developed into therapies for memory loss.
