The concurrent validity of learning potential and psychomotor ability measures for the selection of haul truck operators in an open-pit minePelser, Marikie Karen 11 1900 (has links)
The purpose of the present study was to determine the concurrent validity of learning potential and psychomotor ability measures for the prediction of haul truck operator (N=128) performance in an open-pit mine. Specific aims were to determine the nature of the relationship between learning potential and psychomotor ability; whether there are higher order cognitive or psychomotor factors present in the combined use of the TRAM 1 and Vienna Test System measures; and the relative contribution of learning potential and psychomotor ability in the prediction of haul truck operator performance. The validity of learning potential and psychomotor ability measures was partially supported. A positive correlation between general (cognitive) ability (g) and psychomotor ability was reported. Factor analysis provided relatively consistent evidence for a general (cognitive) ability factor (g) underlying performance on all measures. The relative contribution of learning potential and psychomotor ability in the prediction of performance could not be established. / Industrial and Organisational Psychology / M. Com.

The concurrent validity of learning potential and psychomotor performance compared to safe working behaviour of machine operations in a platinum mineKeyser, Karin 03 1900 (has links)
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. (Industrial and Organisational Psychology))

Psychomotor ability and learning potential as predictors of driver and machine operator performance in a road construction companyOlivier, Louis Petrus 06 1900 (has links)
The changing nature of work and its competitive characteristics are global phenomena and are mainly fuelled by ongoing technological advancement. This creates unique challenges for talent attraction and the retention of high performing individuals. In addition, the global workforce is becoming more diverse due to demographic, societal and cultural changes and companies are placing greater demands on employee competency and performance. Managing the human factor as a strategic asset in organisations remains a primary challenge in securing a competitive advantage.
The road construction industry in South Africa is no different. There is growing competition between civil engineering contractors to secure tenders and to maximise profitability. This is only possible with a sufficient and sustainable labour force. Valid selection processes are therefore required to ensure that the most productive individuals are selected for the most suitable jobs. Reliable and valid performance predictors will assist employers in making appropriate selection decisions. Selecting high performing individuals will support and enhance overall organisational performance.

In this study the investigation focused on whether psychomotor ability and learning potential are statistically significant predictors of work performance - with specific reference to drivers and machine operators in a road construction company. A quantitative approach was followed to investigate the relationships between variables, or then the prediction of one dependent variable (driver and machine operator performance) by means of two independent variables (psychomotor ability and learning potential).
Results from the study did not indicate any statistically significant relationships between the variables. Only scientifically validated assessment instruments were used in the study - which means the findings led to a renewed focus on the importance of performance measurement and the psychometric quality (reliability and validity) of performance data. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology)

Evaluering van die Vienna toetsbattery in die voorspelling van effektiewe busbestuurder gedragDu Toit, Martina Petronella 30 November 2006 (has links)
Vehicle accidents by means of Public transport annually leads to a large number of passenger deaths and life long disablement. AsDu Toit, Martina Petronella
a result, there is a need for preventative measures by identifying the psychomotor abilities of bus drivers during the recruitment and selection process of employment. The study was conducted among 398 bus drivers employed by a large bus company. The Vienna Test Battery was administered. It was found that distance estimation, ability to recognize forms and figures, concentration ability, eye-hand feet coordination and two-hand coordination predicted the effectiveness of bus drivers successfully. It is suggested that further research should focus on client services, attitude of bus drivers and learning potential, as factors that influence the effectiveness of bus drivers. / Industrial psychology / M.A. (Industrial Psychology)
