The feasibility of an automated eye-tracking-modified Fagan test of memory for human faces in younger Ugandan HIV-exposed children

Objective: The Fagan Test of Infant Intelligence (FTII) uses longer gaze length for unfamiliar versus familiar human faces to gauge visual-spatial encoding, attention, and working memory in infants. Our objective was to establish the feasibility of automated eye tracking with the FTII in HIV-exposed Ugandan infants.

Method: The FTII was administered to 31 perinatally HIV-exposed noninfected (HEU) Ugandan children 6–12 months of age (11 boys; M = 0.69 years, SD = 0.14; 19 girls; M = 0.79, SD = 0.15). A series of 10 different faces were presented (familiar face exposure for 25 s followed by a gaze preference trial of 15 s with both the familiar and unfamiliar faces). Tobii X2-30 infrared camera for pupil detection provided automated eye-tracking measures of gaze location and length during presentation of Ugandan faces selected to correspond to the gender, age (adult, child), face expression, and orientation of the original FTII. Eye-tracking gaze length for unfamiliar faces was correlated with performance on the Mullen Scales of Early Learning (MSEL).

Results: Infants gazed longer at the novel picture compared to familiar across 10 novelty preference trials. Better MSEL cognitive development was correlated with proportionately longer time spent looking at the novel faces (r(30) = 0.52, p = .004); especially for the Fine Motor Cognitive Sub-scale (r(30) = 0.54, p = .002).

Conclusion: Automated eye tracking in a human face recognition test proved feasible and corresponded to the MSEL composite cognitive development in HEU infants in a resource-constrained clinical setting. Eye tracking may be a viable means of enhancing the validity and accuracy of other neurodevelopmental measures in at-risk children in sub-Saharan Africa.     

Directional discrepancy between implicit and explicit power motives is related to well-being among managers

This study investigates explicit –implicit motive discrepancies and their effect on well-being. Participants were 382 executive managers (107 females and 275 males). Female managers had higher explicit affiliation scores than males, whereas male managers had marginally significant higher explicit power scores than females. Males and females did not differ in their implicit motives. We expected a directional discrepancy on the power motive (explicit vs. implicit: “Striving for goals without gaining pleasure from doing so”) to predict impaired well-being. Results were consistent with this hypothesis, using polynomial regression analysis with response surface methods, instead of calculating motive difference scores. Discrepancies in the achievement and affiliation motives were not related to well-being. Results are discussed considering the specificity of motive discrepancies for selected groups, such as managers, and the importance of distinguishing between absolute versus directional motive discrepancy scores in motivation research.     

A critical appraisal of heterosexism in Zambia

On 24 February 2012, then United Nations Secretary-General Ban Ki-moon visited Zambia for three days. His call to respect human rights and give protection to all people regardless of sexual orientation was received mostly with hostility by the Zambian public. The media was inundated with opposing press statements from both government and civil society persons and entities. Politicians, church leaders, and the public widely condemned Ban's advocacy for “gay rights”. Although the debate on homosexuality is not new in Zambia, there is a dearth of research on the subject. This paper seeks, modestly, to re-examine popular rationale for heterosexism to contribute to the resolution of one of the perennial problems colouring African political, social, and cultural discourse. By deconstructing the popular views and systematising the debate, the paper aims at providing a baseline and guideline for addressing the problem of heterosexism in Zambia. Without suggesting that Africa is homogenous, what happened in Zambia following Ban's visit could have predictably happened in many African countries, notably Uganda and Nigeria. This paper, however, uses Zambia as a point of reference. The paper relies on views indicating negative attitudes and beliefs that legislators, and policy makers, church leaders and ordinary citizens have toward homosexuality. These positions have been thematised into six major grounds for the sexual prejudices against homosexuality. These are subjected to logical and epistemic scrutiny. Ultimately, the arguments in support of heterosexism are shown to be untenable.     

Dissociation of reward and effort sensitivity in methcathinone‐induced Parkinsonism

Methcathinone‐induced Parkinsonism is a recently described extrapyramidal syndrome characterized by globus pallidus and substantia nigra lesions, which provides a unique model of basal ganglia dysfunction. We assessed motivated behaviour in this condition using a novel cost‐benefit decision‐making task, in which participants decided whether it was worth investing effort for reward. Patients showed a dissociation between reward and effort sensitivity, such that pallidonigral complex dysfunction caused them to become less sensitive to rewards, while normal sensitivity to effort costs was maintained.     

The Experience of Minorities Under Pakistan's Blasphemy Laws

Human rights activists repeatedly assert that the blasphemy laws of Pakistan are discriminatory and violate human rights guaranteed by both the Constitution of Pakistan and international treaties. However, supporters of the blasphemy laws vehemently disagree with this view. They argue that Pakistan's blasphemy laws are not discriminatory and apply equally to all citizens of Pakistan. In support of this, they offer the evidence that the majority of those accused of blasphemy belong to the Muslim community. This article examines this argument in the light of the experience of minorities living under Pakistan's blasphemy laws. While the blasphemy laws have undoubtedly affected all the minority groups in Pakistan to a greater or lesser extent, this article will focus on Christians and Ahmadis as these are the two minorities most affected by the blasphemy laws.
