The researcher selected a quantitative cross-sectional design to test the concurrent validity of learning potential and psychomotor ability by evaluating the relationships between mining machine operators’ learning potential and psychomotor ability as well as their work safety behaviour. Work safety behaviour was considered indicative of their capability to operate a moving machine. The utilization of measuring instruments capable of measuring their learning potential and psychomotor ability and measuring safety behaviour by means of their safety score cards provided the required measurement data. The study involved a quantitative investigation into the relationship between learning potential and psychomotor ability as independent variables and safety behaviour as dependent variable. De Vos, Strydom, Fouche and Delport (2002, p.79) defined quantitative research as “based on positivism, which takes scientific explanation to be nomothetic. Its main aims are to measure the social world objectively, to test hypotheses and to predict and explain human behaviour. A quantitative study may therefore be defined as an inquiry into social or human problems based on testing a theory composed of variables, measured with numbers and analysed with statistical procedures in order to determine whether the predictive generalization of the theory holds true.” The aim of the study was to determine the learning potential and psychomotor ability of mining machine operators as well as compare the following sub-groups (based on the biographical variables): age, years’ experience, educational level and gender. The respondents’ work safety behaviour was measured and the relationship between the two measures of the independent variables (learning potential and psychomotor ability) and work safety behaviour determined. / Industrial & Organisational Psychology / (M.Comm.
