Construct Validity of Raven's Advanced Progressive Matrices for African and Non‐African Engineering Students in South Africa

We test the hypothesis that the Raven's Advanced Progressive Matrices has the same construct validity in African university students as it does in non‐African students by examining data from 306 highly select 17‐ to 23‐year olds in the Faculties of Engineering and the Built Environment at the University of the Witwatersrand (177 Africans, 57 East Indians, 72 Whites; 54 women, 252 men). Analyses were made of the Matrices scores, an English Comprehension test, the Similarities subscale from the South African Wechsler Adult Intelligence Scale, end‐of‐year university grades, and high‐school grade point average. Out of the 36 Matrices problems, the African students solved an average of 23; East Indian students, 26; and White students, 29 (p<.001), placing them at the 60th, 71st, and 86th percentiles, respectively, and yielding IQ equivalents of 103, 108, and 118 on the 1993 US norms. The same pattern of group differences was found on the Comprehension Test, the Similarities subscale, university course grades, and high‐school grade‐point average. The items on the Matrices ‘behaved’ in the same way for the African students as they did for the non‐African students, thereby indicating the test's internal validity. Item analyses, including a confirmatory factor analysis, showed that the African/non‐African difference was most pronounced on the general factor of intelligence. Concurrent validity was demonstrated by correlating the Matrices with the other measures, both individually and in composite. For the African group, the mean r=.28, p<.05, and for the non‐African group, the mean r=.27, p<.05. Although the intercepts of the regression lines for the two groups were significantly different, their slopes were not. The results imply that scores on the Raven's Matrices are as valid for Africans as they are for non‐Africans.     

Jensen Effects and African/Coloured/Indian/White differences on Raven's Standard Progressive Matrices in South Africa

A test is made to determine whether various ethnic group differences on tests of cognitive performance in South Africa are like the Black/White differences in the United States in being positively associated with a tests' g loadings, where g is the general factor of intelligence. A non-parametric re-analysis is made of data from 1056 White, 1063 Indian, 778 mixed-race “Coloured,” and 1093 Black 14 year olds on the Raven's Standard Progressive Matrices Test in South Africa, given without time limits by Owen (1992) [Personality and Individual Differences, 13, 149]. The new analyses showed that the more highly correlated an item was with g, the more it predicted the White/Indian/Coloured/African differences on the test (Spearman's rhos from 0.35 to 0.85; all Ps<0.01). The effects remained regardless of which group g was extracted from. Understanding group differences around the world requires new research on the nature and nurture of g.

Psychometric Properties of the Right Wing Authoritarianism Scale in Black and White South African Students

Recently Taylor and Boeyens (1991) showed that the South African Personality Questionnaire has inadequate internal consistency and factorial validity for use in the black population. This paper reports a study supporting their conclusion that scales developed with data from a white sample do not hold together psychometrically or conceptually when used with a black sample. In a sample of white students, Altemeyer's Right Wing Authoritarianism scale, initially developed in Canada, had an acceptable alpha of 0.83, but there was an unacceptable alpha of 0.43 in a black student sample. Item and factor analysis showed that for the black sample there was little structure and that the scale was effectively a set of heterogenous items. This paper presents a detailed discussion of the item and factor analyses and shows how certain items have different connotations for whites and blacks as a result of their different political and cultural histories. Although cultural differences in conservatism can be observed by looking at individual items, a comparison between black and white individuals on the higher order construct of Authoritarianism cannot be made. It is concluded that basic conceptual work based on the phenomenology of the concept being measured needs to precede the psychometric development of scales for use in the black community.     

Attitudes Toward Abortion in a Sample of South African Female University Students

This study examines the structure of abortion attitudes in a sample of 124 full-time female university residence students, the relationship between self-rated religiosity and abortion attitudes, as well as their knowledge of the Choice on Termination of Pregnancy Act passed in South Africa in 1996. The data provide evidence for the existence of an underlying structure of abortion attitudes, which is complex and multifaceted. Almost 76% of the students described themselves as religious to very religious , and a pronounced trend toward pro-life is evident.     

Condom Use Among South African University Students in the Province of KwaZulu-Natal

South Africa has one of the highest HIV infection rates in the world, with young people particularly affected. Condoms are an effective preventative method against HIV among sexually active adults. This study assessed the level of condom usage among university students in South Africa and their attitudes towards condom usage, negotiation efficacy and confidence in condom usage. It was a cross-sectional study conducted amongst South African university students living at the university residences. Students were randomly selected and required to complete a self-administered questionnaire. The mean age of participants (n?=?441) was 22.7?±?4.3 years. The mean age of sexual debut was 17.7?±?3.0 years with 1.4?±?1.47 (range 0–13) current partners. Less than half of the students used a condom at sexual debut and only 28.5% used condoms during recent sexual activity. Those students who used a condom at first sexual intercourse had marginally more positive attitudes about condom usage than those who did not do so (p?=?0.056). Students with a single current partner had more positive attitudes about condom usage than those with multiple current partners (p?=?0.021). Only 32.5% (n?=?127) of the students were very confident in using condoms. Similarly, only 33.0% (n?=?130) of the participants felt that they could definitely negotiate condom use with their partners. We conclude that condom use among South African students is low and that they lack the confidence to use condoms. We recommend that programmes to step up condom use must also incorporate educational interventions on usage.     

The induction of solution rules in Raven's Progressive Matrices Test

In a passive task participants recall material in the format in which it was presented, whereas in an active task they transform or manipulate the material. Experiment 1 describes an active visuo-spatial task that is vulnerable to the effects of ageing, and Experiment 2 shows that it is more sensitive to the effects of ageing than a passive task carried out concurrently using the same material. In Experiment 3, similar results were obtained using active and passive verbal tasks carried out concurrently using the same material. Finally, these findings were replicated in Experiment 4 using active and passive verbal and visuo-spatial tasks that were carried out in separate experimental conditions. It is concluded that effects of ageing show an earlier onset in tasks requiring active processing than in tasks requiring the passive storage of information.     

Dynamic Testing in Selection for an Educational Programme: Assessing South African Performance on the Raven Progressive Matrices

This article describes the research results of an investigation into the use of dynamic testing for the selection of candidates for an educational programme. The selection of students from educationally disadvantaged backgrounds for mathematics‐, science‐, and technology‐based programmes is a problem for which most South African higher education institutions still have to find adequate solutions. Dynamic testing procedures are often seen as more fair to use for selection than single‐session tests in situations of unequal educational opportunity. The possibility that a selection instrument using a dynamic testing process could add significantly to the selection effectiveness already achieved in a South African mathematics and science foundation year using single‐session tests was investigated. The performance of a group of educationally disadvantaged black South African students on the Raven Progressive Matrices is compared to that of other groups reported in research literature. Considering the disadvantaged nature of the South African group, the group performed well on the Raven test when compared with data from other countries.     

Normative data for Raven's Coloured Progressive Matrices scale in Yemen

Results are reported for a standardization sample of 986 6- to 1-yr.-olds for the Coloured Progressive Matrices in Yemen. Younger children performed better than older children relative to British norms, and there was no significant sex difference in means or variability. In relation to a British IQ of 100 (SD=15), the sample obtained an average IQ of approximately 81.     

Formal Operational Reasoning in African University Students

Few studies have investigated formal operational concepts among Africans. The present study examined formal operational reasoning among African university students. Both Piagetian and neo-Piagetian criteria of 75% and 50% success rate were used for determining the presence of formal operational concepts. Three formal operational concepts—propositional, proportional, and combinatorial reasoning—were assessed among African university students.     

Knowledge,Beliefs and Attitudes Regarding Abortion in South Africa Among a Sample of University Students

A survey study design was used to determine the knowledge of a sample of South African university students regarding the Choice on Termination of Pregnancy (CTOP) Act and their beliefs and attitudes toward abortion. A total of 146 (110 female, 36 male) undergraduate psychology students participated in the study. As part of a larger study participants were given a questionnaire on knowledge, beliefs, attitudes and practices regarding sexuality among young South Africans. The results showed that most of the students were unaware of key provisions of the Act. The data also indicated opposition to abortion except in the case of rape or when the pregnancy posed a threat to the health of the woman. It is concluded that increasing public awareness of the Act is vital not only in improving access to abortion services but also in terms of reducing the stigma that seems to be associated with abortion in South Africa.     

Ambivalence Toward Men: Comparing Sexism Among Polish, South African and British University Students

This study extends the literature on attitudes toward gender roles by exploring whether the nature of sexism (i.e., benevolence and hostility directed at men) differs among university students from two under-researched countries, Poland (n?=?190) and South Africa (n?=?188), in a comparison with students in the United Kingdom (n?=?166). Based on empirical literature applying Ambivalent Sexism Theory, and in the light of the socio-political context, it was hypothesized that: (1) both hostile and benevolent attitudes toward men in Poland would be more liberal than in South Africa and more conservative than in the United Kingdom, and (2), women would exhibit more hostile but less benevolent attitudes than men in relatively more conservative South Africa. The Ambivalence to Men Inventory was used to measure the two types of sexist attitudes about men. Findings supported the first hypothesis for hostile attitudes and partially for benevolent attitudes. South African and Polish students were more benevolent and hostile to men than British students, and students from South Africa were more hostile than those from Poland. Moreover, as predicted, a significant country-by-gender interaction revealed that South African women had more hostile and less benevolent attitudes to men than South African men. No such gender gap was present in the case of hostile attitudes in Poland and benevolent attitudes in the United Kingdom. Findings are discussed in terms of Ambivalent Sexism Theory and the countries’ socio-cultural context.     

How to Gain Eleven IQ Points in Ten Minutes: Thinking Aloud Improves Raven's Matrices Performance in Older Adults

ABSTRACT

Few studies have examined the impact of age on reactivity to concurrent think-aloud (TA) verbal reports. An initial study with 30 younger and 31 older adults revealed that thinking aloud improves older adult performance on a short form of the Raven's Matrices (Bors & Stokes, 1998 Bors, D. A. and Stokes, T. L. 1998. Raven's Advanced Progressive Matrices: Norms for first-year university students and the development of a short form. Educational and Psychological Measurement, 58: 382–398. [Crossref], [Web of Science ®] , [Google Scholar], Educational and Psychological Measurement, 58, p. 382) but did not affect other tasks. In the replication experiment, 30 older adults (mean age = 73.0) performed the Raven's Matrices and three other tasks to replicate and extend the findings of the initial study. Once again older adults performed significantly better only on the Raven's Matrices while thinking aloud. Performance gains on this task were substantial (d = 0.73 and 0.92 in Experiments 1 and 2, respectively), corresponding to a fluid intelligence increase of nearly one standard deviation.     

The Subjective Experience of Using Ignatian Meditation by Male and Female South African University Students: An Exploratory Study

This study is set out to examine the subjective experience of using the Ignatian method of meditation to reflect on and pray through Ruth 2. A group of male and female Theology students from the University of KwaZulu-Natal were invited to reflect upon/pray through Ruth 2 using Ignatian meditation. Following this exercise, participants were invited to participate in a focus group in which they shared their experience of this exercise, focusing particularly on some of the gendered aspects of the experience. The transcribed focus group material was subjected to a critical thematic analysis, in order to identify which core aspects of the experience of using this method of meditation and reflection were responsible for the reported subjective experiences. The analysis also included a comparison of the experience for men and women participating in this exercise, and the differential effect of various aspects of the exercise on men and women.     

The reliability and validity of Raven's Standard Progressive Matrices for Irish apprentices

The Standard Progressive Matrices (SPM) is a 'test of a person's capacity at the time of the test to apprehend meaningless figures presented for his observation, see the relations between them, conceive the nature of the figure completing each system of relations presented and, by so doing, develop a systematic method of reasoning' (Raven et al., 1983, p. 2). It was developed in Britain in the mid-1930s (see Penrose and Raven, 1936) as a non-verbal measure of Spearman's 'g' factor, eduction of relations among abstract items.     

Klopfer's Prognostic Scale Used with Raven's Progressive Matrices in Play Therapy Prognosis

Summary: The influence of buffer items on response to the MarloweCrowne Social Desirability Scale (MC) was examined. Thirty-four college student subjects received MC questionnaires with intermixed extraversion and neuroticism items, while 35 others received separate MC and extraversion-neuroticism questionnaires. MC means under the two conditions differed nonsignificantly, and confidence interval estimation spoke against the likelihood of any appreciable buffer item effect. Little insight into the purpose of MC was exhibited—less than half that previously reported by Shrauger (1972)—nor was it related to the buffer item manipulation.     

The Structure of Parental Bonding in South African Students

The Parental Bonding Instrument (PBI: Parker, Tupling & Brown, 1979) offers a practical way of conceptualizing parental experiences. In the present study, PBI scores of 522 students from a South African university were factor analyzed, yielding a three-factor structure for the maternal-PBI subscale. However, the paternal-PBI data were interpretable only for a four-factor solution. Confirmatory factor analyses were conducted and Kendler's (1996) three-factor model offered the best-fit to the maternal-PBI data. The regression analyses on depression versus PBI factors of warmth, protectiveness and authoritarianism showed that higher parenting-style scores of maternal authoritarianism and paternal warmth increased the subjective experience of depression, and paternal protectiveness predicted a decrease of depression reports.
