Why don’t synaesthetic colours adapt away?

Synaesthetes persistently perceive certain stimuli as systematically accompanied by illusory colours, even though they know those colours to be illusory. This appears to contrast with cases where a subject??s colour vision adapts to systematic distortions caused by wearing coloured goggles. Given that each case involves longstanding systematic distortion of colour perception that the subjects recognize as such, how can a theory of colour perception explain the fact that perceptual adaptation occurs in one case but not the other? I argue that these cases and the relationship between them can be made sense of in light of an existing view of colour perception. Understanding colours as ways in which objects and surfaces modify light, perceived through grasping patterns and variations in colour appearances, provides a framework from which the cases and their apparent disanalogy can be predicted and explained. This theory??s ability to accommodate these cases constitutes further empirical evidence in its favour.     

Competitiveness across the life span: the feisty fifties

Existing theories on life span changes in confidence or motivation suggest that individuals' preferences to enter competitive situations should gradually decline with age. We examined competitive preferences in a field experiment using real financial stakes in 25- to 75-year-olds (N = 543). The critical dependent variable was whether participants chose to perform a simple mental arithmetic task either under a piece-rate payment schedule (i.e., $.25 per solved item) or a competitive payment schedule ($.50 per solved item if the overall score is better than that of a randomly selected opponent, $0 otherwise). Results revealed that competitive preferences increased across the life span until they peaked around age 50, and dropped thereafter. We also found that throughout, men had a substantially larger preference for competing than women-extending previous findings on college-aged participants. The age/gender differences in preferences were neither accounted for by actual differences in performance nor individuals' subjective confidence. This first systematic attempt to characterize age differences in competitive behavior suggests that a simple decline conception of competitiveness needs to be reconsidered.     

Gender Representation in Philippine Television Advertisements

This study analyzed 254 unduplicated primetime Philippine television advertisements from 2010 for differences in gender representation. Two coders independently coded the entire sample and achieved an intercoder reliability of greater than .700 for each reported variable. The findings are based on chi-square analyses and indicate a high prevalence of gender differences and stereotypes in Philippine television advertisements. For example, more males were shown in the workplace (17.9 % vs. 7.4 %), whereas more females were shown at home (45.9 % vs. 24.5 %); males were generally fully clothed (88.7 % vs. 44.6 %), whereas females were often suggestively dressed (52.7 % vs. 6.6 %); more males than females delivered voiceovers (46.1 % vs. 35.0 %); and product categories were stereotypically associated with gender. The only exception to these traditional, stereotypical gender portrayals was the predominance of female primary characters in television advertisements (58.3 % vs. 41.7 %). Overall, such stereotypical portrayals do not accurately reflect Philippine society, which is considered to be one of the most egalitarian Asian societies with regard to gender. By analyzing Philippine television advertisements, this study intends to close a gap in the still under-researched area of gender representation in developing countries, which could provide a more complete picture of this topic from an international perspective. The similarities and differences between this research and previous studies on this topic in developing and developed countries are examined. The possible effects of such representation on audiences are discussed based on social cognitive theory and cultivation theory.     

A Constructivist Pedagogue's Personal Narrative of Integrating Faith with Learning: Epistemological and Pedagogical Challenges

This article offers a personal narrative about integrating the Christian faith into the process of teaching and learning. The author begins by describing his understanding of pedagogy that framed his beliefs about teaching in higher-education environments. Understanding the author's beliefs provides a context for his experiences in integrating faith with learning. Specifically, the author offers three tensions of faith integration and describes how pedagogy helped him overcome these tensions.     

Illuminating and Applying “The Dark Side”: Insights From Elite Team Leaders

In contrast to socially desirable behaviors, recent work has implied that effective elite team leadership also relies on socially undesirable behaviors. Accordingly, this study aimed to further explore the authenticity of dark side leadership behaviors, what they look like, and how they may be best used. Via interviews with 15 leaders, behaviors associated with Machiavellianism/mischievousness, skepticism, social dominance, and performance-focused ruthlessness were found. Moreover, these behaviors were enabled by leaders’ sociopolitical awareness and engineering as well as their adaptive expertise. Findings promote practitioner sensitivity to dark side leadership and, for leader effectiveness, sociopolitical and temporal features of its application.     

It's All in the Mind: PETTLEP-Based Imagery and Sports Performance

Two studies examined the effects of PETTLEP-based imagery compared to more traditional imagery interventions. PETTLEP imagery aims to produce a realistic and more functionally equivalent imagery experience than traditional imagery methods through factors such as wearing the correct clothing or imaging in the correct environment. In Study 1, 48 varsity hockey players were divided into four groups: “Sport-specific” imagery, “clothing” imagery, “traditional” imagery, and control. Imagery participants imaged 10 penalty flicks daily for six weeks, and controls spent an equivalent time reading hockey literature. In the post-test, the sport-specific group scored significantly higher than the clothing group, who scored significantly higher than the traditional imagery group. In Study 2, 40 junior gymnasts attempted a turning jump on the beam. They were split into four groups: A physical practice group, a PETTLEP imagery group, a stimulus only imagery group, and a control (stretching) group. Each group performed their task three times per week for six weeks. Both the physical practice and PETTLEP groups improved significantly from pre-test to post-test, with no significant difference between them, but the stimulus and control groups did not improve significantly. Taken together the results from Study 1 and 2 provide support for the efficacy of PETTLEP-based imagery over more traditional imagery interventions.     

Testing Practices and Attitudes Toward Tests and Testing: An International Survey

On behalf of the International Test Commission and the European Federation of Psychologists' Associations a world-wide survey on the opinions of professional psychologists on testing practices was carried out. The main objective of this study was to collect data for a better understanding of the state of psychological testing worldwide. These data could guide the actions and measures taken by ITC, EFPA, and other stakeholders. A questionnaire was administered to 20,467 professional psychologists from 29 countries. Five scales were constructed relating to: concern over incorrect test use, regulations on tests and testing, internet and computerized testing, appreciation of tests, and knowledge and training relating to test use. Equivalence across countries was evaluated using the alignment method, four scales demonstrated acceptable levels of invariance. Multilevel analysis was used to determine how scores were related to age, gender, and specialization, as well as how scores varied between countries. Although the results show a high appreciation of tests in general, the appreciation of internet and computerized testing is much lower. These scales show low variability over countries, whereas differences between countries on the other reported scales are much greater. This implies the need for some overarching improvements as well as country-specific actions.     

Might “unique” factors be “common”? On the possibility of indeterminate common–unique covariances

The present paper shows that the usual factor analytic structured data dispersion matrix Λ Ψ Λ′ + Δ can readily arise from a set of scores y = Λ η + ε, where the “common” (η) and “unique” (ε) factors have nonzero covariance: Γ = Covε,η) ≠ 0. Implications of this finding are discussed for the indeterminacy of factor scores, and for the issue of invariance of factor analytic covariance models. The size of the problem is explored with numerical examples.
