The Draw-a-Scientist Test in an African context: comparing students’ (stereotypical) images of scientists across university faculties

Background: People’s perceptions of scientists have repeatedly been investigated using the Draw-a-Scientist Test (DAST). The test is used to identify people’s (stereotypical) images of scientists, which might affect attitudes towards science and science-related career choices.

Purpose: The current study has two goals. (1) Applying the DAST at a university in South Africa, the study will add to the existing research literature through its Southern African context. (2) The study will also look more closely at the link between (stereotypical) images of scientists and science-related career choices.

Sample: The DAST was applied to first-year students (n = 445) across different faculties at a South African university. If the assumption that young people’s perceptions of scientists influence their career choice is correct, one would expect differences in the drawings made by students who have opted for different fields of study.

Design and methods: The DAST was administered during orientation week of the first-year students in January 2017. Students were provided with a prepared blank sheet of paper and asked to draw a scientist and to fill in further information on the back of the paper. A content analysis applying the DAST checklist was used to analyse the images.

Results: The findings show that South African students use about four stereotypical indicators when drawing a scientist, and social science students drew stereotypical attributes more frequently when compared to students from other faculties. A typical scientist – as depicted in this study – is a man of uncertain age, who wears eyeglasses and a lab coat, and is surrounded by laboratory equipment.

Conclusions: Findings are largely in line with the international research literature. To challenge gender stereotypes, more contact between students and female role models might be essential. If (stereotypical) images really affect science-related career choices deserves further attention in future research studies.

Social Justice in Sport and Exercise Psychology: A Position Statement

ABSTRACT

There are varied approaches that have been used in sport for development (SFD) projects. This article is focused on the move by sport and exercise psychology researchers toward community-based SFD projects where marginalized groups are centralized. The authors have chosen two of their projects to exemplify different approaches to SFD. An initial project with an Aboriginal community is critically examined to reveal cultural missteps that perpetuated cultural colonization–something antithetical to community capacity building. The second project is then considered because of its closer alignment with cultural praxis and community capacity building. This second project focuses on the initial developments of a YMCA physical activity project designed to meet the needs of forced immigrants (a self-titled name developed by the refugee community members) and the staff who work with them. We culminate with five postulates proposed for SFD project teams derived from our vantage in sport and exercise psychology, where community engagement and eventual self-governance are imperatives.     

Associative structure of second-order conditioning in humans

Second-order conditioning (SOC; i.e., conditioned responding to S2 as a result of S1–US pairings followed by S2–S1 pairings) is generally explained by either a direct S2→US association or by an associative chain (i.e., S2→S1→US). Previous research found that differences in responses to S2 after S1 was extinguished often depended on the nature of the S2–S1 pairings (i.e., sequential or simultaneous). In two experiments with human participants, we examined the possibility that such differences result from S1 evoking S2 during extinction of S1 following simultaneous but not sequential S2–S1 pairings. This evocation of S2 by S1 following simultaneous pairings may have paired the evoked representation of S2 with absence of the outcome, thereby facilitating mediated extinction of S2. Using sequential S2-S1 pairings, both Experiments 1 and 2 failed to support this account of how extinction of S1 reduced responding to S2. Experiment 1 found that extinguishing S1 reduced responding to S2, while extinguishing S2 had little effect on responses to S1, although forward evocation of S1 during extinction of S2 paired the evoked representation of S1 with absence of the outcome. In Experiment 2, evocation of S2 during S1 nonreinforced trials was prevented because S2–S1 pairings followed (rather than proceeded) S1-alone exposures. Nevertheless, responding to S2 at test mimicked S1 responding. Responding to S2 was high in the context in which S1 had been reinforced and low in the context in which S1 had been nonreinforced. Collectively, these experiments provide additional support for the associative-chain account of SOC.     

Assessing visibility,legibility and comprehension for interactive whiteboards (IWBs) vs. computers

The usability of interactive whiteboards vs. computers was evaluated on three dimensions (visibility, legibility and comprehension) in the secondary school pupils. The visibility assessment consisted in detecting a visual stimulus varying in luminance using a staircase procedure, legibility was assessed with a target-search task, and we administered narrative and explanatory texts with or without illustrations to evaluate comprehension. The results of the visibility test showed that pupils found the light signal easier to detect on the IWB. For the legibility test, we observed differences in error rates and discriminability according to medium, font size and congruence between target and the distractor letters. Performances in the comprehension test were similar for both explanatory and narrative texts. Moreover, the presence of illustrations does not improve comprehension. These results could be related to the hierarchical structure of the texts, which facilitate comprehension.     

Qualité De L’éducation En Afrique: Le Rôle Potentiel Des Tic

THE QUALITY OF EDUCATION IN AFRICA: THE ROLE OF ICTS IN TEACHING – This article reports on the presence of ICT in educational institutions, presents an overview of the types of ICT uses found in African schools, and explores the relations between ICT use and the quality of education. Data were obtained from a transnational research project (Projet des écoles pionnières-TIC en Afrique / Pioneer ICT-Schools Project in Africa) funded by the International Research Development Centre (IDRC) of Canada. A total of 68,662 students, 2,627 teachers, 217 school administrators, and 428 additional education stakeholders in West and Central Africa participated in the study. The results show multiple uses of ICT in the participating schools, albeit centered on teaching ICT basic skills. A biaxial model with four quadrants is used to visualize the range of ICT usages in the schools. The analysis reveals a limited pedagogical use of ICT to teach academic subjects in most of the schools. Approximately 80% of the reported uses involved teaching ICT basic skills, while barely 17% involved subject-specific ICT integration for teaching and learning purposes.     

The Impact of Inclusion on Children's Lives: Multiple outcomes,and friendship in particular

This paper describes the work of a Consortium for Collaborative Research on the Social Relationships of Children and Youth with Diverse Abilities. The Consortium was a 5 year research institute funded by the US Department of Education, carrying out research in the Los Angeles, San Francisco, and Sacramento areas of California; the Seattle and rural-suburban regions of Washington State; New York State including New York City, Syracuse and rural regions; and Maryland. The work was undertaken in rural, urban, and suburban school districts, with a demographically diverse population, and also directly with families. This paper shares the results of research findings on children's social lives in inclusive settings, while weaving a theme throughout the presentation of how this research was done. The focus was upon the role research should play and was directed toward closing the gap between research and practice.     

Cortisol in Neonatal Mother's Milk Predicts Later Infant Social and Cognitive Functioning in Rhesus Monkeys

Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother–infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex‐differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the “lactational programming” hypothesis on the impact of maternal‐origin hormones ingested via milk.     

Self‐paced segmentation of written words on a touchscreen tablet promotes the oral production of nonverbal and minimally verbal children with autism

We investigated in a pilot study the effects of various types of visual mediation (photos, written words and self‐paced syllabic segmentation of written words displayed on a touchscreen tablet) that are thought to facilitate the oral production of nonverbal and minimally verbal children with autism, according to the participants’ level of oral language development and, more specifically, their ability to produce delayed echolalia. We also sought to identify the cognitive characteristics that need to be taken into account when seeking to develop the oral production of nonverbal children with autism. Results showed that the nonverbal and minimally verbal children with autism were able of using written words to produce them orally. Their performance was largely dependent on their level of language development. Tasks combining written and oral modalities prompted some of them to engage in oral production for the first time (isolated syllables for nonverbal children) and allowed others to produce non‐random strings of syllables (minimally verbal children).
