Influence of stimulus symmetry and complexity upon haptic scanning strategies during detection,learning, and recognition tasks

Two experiments were conducted to investigate the perceptual processes involved in haptic exploration of randomly generated shapes. Experiment 1 required subjects to detect the symmetrical or asymmetrical characteristics of individually presented plastic shapes. The shapes also varied in complexity as measured by the number of sides. Experiment 2 involved learning a set of shapes and then attempting to recognize these “old” shapes when presented together with a series of “new” shapes. In both experiments, reaction time was investigated as a function of stimulus complexity and task requirements. Furthermore, it was observed that an initial orienting response was used to direct the subjects to adopt specific scanning strategies when examining asymmetrical or symmetrical shapes. The influences of stimulus properties and task requirements upon haptic encoding processes are discussed.     

Psychometric Analysis and Tentative Shortening of Survey of Personal Beliefs

The Survey of Personal Beliefs (SPB) is a frequently used measure of irrational beliefs, but can display less than ideal psychometric properties. In the first study of the present project, the five subscales of the SPB correlated as expected with higher levels of perfectionism, shame, and guilt. A confirmatory factor analysis, nevertheless, revealed that these subscales did not adequately describe responding on the SPB, and internal reliability for some subscales was poor. An abbreviated 12-item version of the SPB was more reliable than the subscales and generally as valid as the full 50-item instrument. With a second data set, the shortened version of the SPB was more consistent than the full 50-item scale in correlating positively with at least some measures of maladjustment that included depression, anxiety, neuroticism, and alexithymia. Future researchers may want to utilize the shorter 12-item version of the SPB as a more convenient and psychometrically acceptable measure of irrational beliefs.     

Construction of Smoking-Relevant Risk Perceptions Among College Students: The Influence of Need for Cognition and Message Content1

Changing smokers' health-risk perceptions has been difficult. This study tested whether need for cognition (NC)—a factor within Petty & Cacioppo's (1986) elaboration likelihood model that reflects the preference for effortful cognitive information processing—moderated responses to a smoking risk message intervention. College smokers (n=227) evaluated a fact-based or emotion-based smoking risk pamphlet or a control pamphlet. Among occasional but not daily smokers, NC interacted as hypothesized with type of message to moderate risk perceptions. Among participants with higher NC, the fact-based message produced the greatest increase in risk perception; whereas among participants with lower NC, the emotion-based message produced the greatest change. Findings demonstrate that individual differences in cognitive processing can influence the potency of health-risk messages.     

Pretreatment task persistence predicts smoking cessation outcome

R. Eisenberger's (1992) learned industriousness theory states that individuals display differing degrees of persistence depending on their history of reinforcement for effortful behavior. These differences may influence the development, maintenance, and cessation of addictive behaviors. In cross-sectional studies, E. P. Quinn, T. H. Brandon, and A. L. Copeland (1996) found that cigarette smokers were less persistent than nonsmokers, and R. A. Brown, C. W. Lejuez, C. W. Kahler, and D. R. Strong (2002) found that smokers who had previously abstained for 3 months were more persistent than those who had never quit. The present study extended these findings by using a prospective design. A pretreatment measure of task persistence (mirror tracing) completed by 144 smokers predicted sustained abstinence throughout 12 months of follow-up. Moreover, persistence predicted outcome independent of other significant predictors: gender, nicotine dependence, negative affect, and self-efficacy.     

Managers' tactics of influence: perceptions of regular and temporary employees

The paper concerns managers' perceived influence tactics with regular and temporary employees. 156 subordinates completed the Behavioral Alteration Techniques Scale. Mean ratings of managers' use of tactics of influence with regular employees were significantly higher than those with temporary employees on 9 of the 22 measured techniques.     

Perception of mistuned harmonics in complex sounds by the bullfrog (Rana catesbeiana)

The ability of 73 male bullfrogs (Rana catesbeiana) to detect single mistuned harmonics in an otherwise periodic signal was studied. Bullfrogs in their natural environment were presented with playbacks of synthetic signals, resembling their species advertisement calls, that differed in the frequency of 1 harmonic component (out of 22). There were significant differences in the number and latency of the males' evoked vocal responses to these stimuli, suggesting that males were sensitive to the differences between the sounds. Differences in envelope shape (rate and depth of amplitude modulation) produced by the harmonic mistunings may underlie the differences in response. Frogs, like birds and humans, can discriminate sounds on the basis of harmonic structure, indicating that this is a general perceptual trait shared among vertebrates.     

Are male tokens bad for females? The effect of social dominance orientation on high‐status tokens' evaluations of low‐status members

Prior research has not given much attention to understanding how those in the numeric minority (i.e., tokens) with high social status (e.g., males) react to those with low social status (e.g., females). We draw from social dominance orientation (SDO) to better understand how male tokens' beliefs about group‐based hierarchies affect their evaluation of a highly qualified female candidate. We conducted a laboratory study in which participants were placed in a selection situation and were asked to evaluate a highly qualified female candidate. We discovered a significant interaction between token status and SDO such that male tokens who were high in SDO were more likely to evaluate negatively a highly qualified female.     

Creating a Self-Plagiarism Research Topic Typology through Bibliometric Visualisation

Self-plagiarism, textual recycling and redundancy seemed to be controversial and unethical; however some questions about its definition are still open. The objective in this paper presented study was to use bibliometric analysis to synthesise and visualize the research literature production and derive a typology of self-plagiarism research. Five topics emerged: Self-plagiarism, Institutional self-plagiarism, Self-plagiarism and ICT, Self-plagiarism in academic writing, Self-plagiarism in science. The state of the art topics seem to be “social medium”, “virtual world”, “face book”, “sociomateriality”, “knowledge sharing”, “open access”, “institutional repository”, “retraction” and “responsible conduct”.
