    ABSTRACT: PurposeTo investigate the application of critical thinking (CT) in medical ultrasound by sonographers in south-eastern Nigeria as a measure of the quality of practice.MethodsA semi-structured questionnaire based on six elements of CT was distributed to 82 sonographers selected through a simple random sampling. The questionnaire investigated the application of the elements of interpretation, analysis, evaluation, inference, explanation and self-regulation involved in CT by medical sonographers. The data for each respondent were categorized into age, experience and the elements of CT. Statistical analyses were done using mean and Spearman's Rank correlation.ResultsThe overall mean score of the practitioners on all the elements of CT application was 8.65 ± 6.76 against a total of 60. The application of CT did not show any correlation with age or clinical experience using Spearman's Rank correlation (r = −0.017; p > 0.05 and r = −0.086; p > 0.05, respectively).ConclusionsThe results show that there is poor application of CT by medical sonographers in the locality which may impact negatively on the outcome of this diagnostic process. Increase in the number of formal training programmes in sonography and inclusion of CT skills in the curriculum are recommended.

    ABSTRACT: 60 male Nigerian prison inmates (30 with convicted status and 30 awaiting trial) and 210 male noninmates were administered the Tennessee Self-concept Scale to test the hypotheses that (1) inmates with convicted status would obtain higher self-concept scores than those with ¿awaiting trial¿ status, and (2) the self-concept scores of prison inmates generally would be lower than those of noninmates. The two hypotheses were strongly supported for this sample. It was concluded that self-concept scores were not only related to delinquency by also to custodial status.

    ABSTRACT: This paper reviews some studies done on the psychological aspects of albinism. Studies on the intellectual ability of albinos produce equivocal results. Results from personality studies seem more consistent and show albinos to be more emotionally unstable than non-albinos. This paper also reports a study by the author which examines the phenomenon of albinism from the albino's viewpoint. It examined the responses of three undergraduate albino subjects--one female and two males--to the author's request for each to write an essay on the merits and demerits of being an albino based on personal experiences. All consider being an albino to be more of a demerit than a merit. The demerits include conspicuous colour, delicate skin which blisters under the sun, defective sight, interpersonal, especially heterosexual, problems and society's unkind attitude. The paper ends with a discussion of possible future research in the area and a recommendation of the need for psychological rehabilitation as part of the management programme for albinos.

    ABSTRACT: The study examined the suitability of Furth's nonverbal conservation test as a psychometric tool for measuring individual differences in Zambia. The subjects included normal and mentally deficient Zambian children aged 7–13 years. The test was validated against age differentiation, differentiation of different intellectual levels, and school performance. The results showed that scores on the test increased significantly with increase in age, correlated positively and significantly with school scores, and differentiated normal from mentally deficient children. Within the normal sample the test also differentiated dull from average children; within the deficient sample the test did not differentiate the moderately mentally deficient from the severely mentally deficient. These results are explained by reference to the characteristics of the test, performance on which requires learning, memory, and perceptual abilities.
