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.     

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.     

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 Confirmatory Approach to Examining the Factor Structure of the Strengths and Difficulties Questionnaire (SDQ): A Large Scale Cohort Study

The aim of this study was to examine the factor structure of the Strengths and Difficulties Questionnaire (SDQ) using a Structural Confirmatory Factor Analytic approach. The Danish translation of the SDQ was distributed to 71,840 parents and teachers of 5–7 and 10–12-year-old boys and girls from four large scale cohorts. Three theoretical models were examined: 1. a model with five first order factors (i.e., hyperactivity/inattention, conduct, emotional, peer problems and prosocial), 2. a model adding two internalising and externalising second order factors to model 1, and 3. a model adding a total difficulties second order factor to model 1. Model fits were evaluated, multi-group analyses were carried out and average variance extracted (AVE) and composite reliability (CR) estimates were examined. In this general population sample, low risk sample models 1 and 2 showed similar good overall fits. Best model fits were found when two positively worded items were allowed to cross load with the prosocial scale, and cross loadings were allowed for among three sets of indicators. The analyses also revealed that model fits were slightly better for teachers than for parents and better for older children than for younger children. No convincing differences were found between boys and girls. Factor loadings were acceptable for all groups, especially for older children rated by teachers. Some emotional, peer, conduct and prosocial subscale problems were revealed for younger children rated by parents. The analyses revealed more internal consistency for older children rated by teachers than for younger children rated by parents. It is recommended that model 1 comprising five first order factors, or alternatively model 2 with additionally two internalising/externalising second order factors, should be used when employing the SDQ in low risk epidemiological samples.     

Dimensions of achievement goal orientation and coping in South African wheelchair rugby players with quadriplegia

This study investigated the relationship between dispositional achievement goal orientation (task and ego) and coping ability in wheelchair rugby players with quadriplegia. The sample consisted of 16 (15 males and 1 female) players between the ages of 25 and 44 (M=33.7 years; SD=8.7) who were selected for South Africa's national training squad in preparation for the 2011 International Wheelchair Rugby Federation (IWRF) Asia-Oceania Championship. Players self-reported on their perception of success and athletic coping skills. The data were analysed for correlational associations between dimensions of achievement goal orientation and psychological skills associated with coping in sport. Findings revealed that players have both high task and fairly high ego orientation of which task orientation was significantly correlated with coping ability.     

Most adults show opposite-side biases in the imagined holding of infants and objects

Three hundred university undergraduates were asked to imagine holding in their arms first an object (either an "expensive vase" or an "old shoebox") and then a young infant. For all three tasks, side biases were found that were significantly different from chance and from one another: 81% of the subjects reported holding the imagined vase in their right arm, 64% reported holding the imagined shoebox in their right arm, and 66% reported holding the imagined infant in their left arm. These results further support the hypothesis that the left-side bias is unique to infants and, for the first time, establish this through direct comparisons of holding-side biases for infants and objects within subjects. The sex and handedness of the holder as well as the qualities of the imagined object also were found to contribute to the side and strength of the bias.
