Fulltext Does the implicit models of leadership influence the scanning of other-race faces in adults?

Densten IL, Borrowman L

PLoS One, 2017;12(7):e0179058.
PMID: 28686605 DOI: 10.1371/journal.pone.0179058

The current study aims to identify the relationships between implicit leadership theoretical (ILT) prototypes / anti-prototype and five facial features (i.e., nasion, upper nose, lower nose, and upper lip) of a leader from a different race than respondents. A sample of 81 Asian respondents viewed a 30-second video of a Caucasian female who in a non-engaging manner talked about her career achievements. As participants watch the video, their eye movements were recorded via an eye tracking devise. While previous research has identified that ILT influences perceptional and attitudinal ratings of leaders, the current study extends these findings by confirming the impact of ILT on the gaze patterns of other race participants, who appear to adopt system one type thinking. This study advances our understanding in how cognitive categories or schemas influence the physicality of individuals (i.e., eye gaze or movements). Finally, this study confirms that individual ILT factors have a relationship with the eye movements of participants and suggests future research directions.

Knowledge, attitudes, and perceptions of epilepsy in Asia: toward a uniform study protocol

Lim SH, Pan A

Knowledge, attitudes, and perceptions of epilepsy (KAPE) among the public play a major role in determining the extent to which people with epilepsy can be integrated into their society.

Colour detection thresholds in faces and colour patches

PMID: 24344549

Human facial skin colour reflects individuals' underlying health (Stephen et al 2011 Evolution & Human Behavior 32 216-227); and enhanced facial skin CIELab b* (yellowness), a* (redness), and L* (lightness) are perceived as healthy (also Stephen et al 2009a International Journal of Primatology 30 845-857). Here, we examine Malaysian Chinese participants' detection thresholds for CIELab L* (lightness), a* (redness), and b* (yellowness) colour changes in Asian, African, and Caucasian faces and skin coloured patches. Twelve face photos and three skin coloured patches were transformed to produce four pairs of images of each individual face and colour patch with different amounts of red, yellow, or lightness, from very subtle (deltaE = 1.2) to quite large differences (deltaE = 9.6). Participants were asked to decide which of sequentially displayed, paired same-face images or colour patches were lighter, redder, or yellower. Changes in facial redness, followed by changes in yellowness, were more easily discriminated than changes in luminance. However, visual sensitivity was not greater for redness and yellowness in nonface stimuli, suggesting red facial skin colour special salience. Participants were also significantly better at recognizing colour differences in own-race (Asian) and Caucasian faces than in African faces, suggesting the existence of cross-race effect in discriminating facial colours. Humans' colour vision may have been selected for skin colour signalling (Changizi et al 2006 Biology Letters 2 217-221), enabling individuals to perceive subtle changes in skin colour, reflecting health and emotional status.

PMID: 19513153

OBJECTIVE: To evaluate the level of knowledge, attitudes, and risk perceptions of University Sains Malaysia final-year pharmacy students regarding human immunodeficiency virus (HIV) and acquired immunity deficiency syndrome (AIDS).
METHOD: A cross-sectional study among pharmacy students. Data were analyzed with Chi-square to find difference at p value < 0.05.
RESULTS: The majority of students (83.07%) responded showing a difference in gender and race. Students showed low willingness (9.2%) to assist patients and low confidence (36.1%) in their education about HIV/AIDS patients. Students recommended HIV testing for health care professionals (69.4%) and patients (75.9%) before surgical procedures. Students knew little about Post Exposure Prophylaxis (18.5%) or about the time for HIV to develop into AIDS (57.4%). About 40% of students were unaware of the inability of antivirals to treat HIV/AIDS. Students had low awareness for opportunistic infections (18.5%), and low agreement on competency to treat and counsel HIV patients (12.9%).
CONCLUSION: The study highlighted students' misconceptions, negative attitudes, and risk perceptions towards HIV/AIDS.
