The potential of cross-lagged correlation analysis in field research

Abstract: Some problems of investigating causal relationships when undertaking field research are outlined. The potential of cross-lagged correlation analysis in this context is assessed by describing the technique, its underlying assumptions and its previous use in applied occupational research. A method for evaluating the technique using simulated data is described. Preliminary findings using this approach show that cross-lagged correlation analysis is a viable technique under relatively straightforward conditions. Nevertheless, further work needs to be done before it is sufficiently well understood to give a high level of confidence in conclusions based on the technique.

Salience, importance and evaluation in judgements about people

Abstract: Three experiments are described which examine the mutual operation of different weighting criteria. The criteria are evaluative direction, and what are termed ‘general salience’ and ‘importance-in-context’. The first experiment establishes a paradigm case where general salience is varied but importance-in-context is controlled. Later experiments extend this paradigm case to stimulus compounds where both general salience and importance-in-context are controlled and to compounds where both are varied. Each experiment employs different stimulus material: trait adjectives, tape-recorded messages and newspaper articles. The three weighting criteria are shown to operate in an apparently non-additive way, in that the influence of one depends upon the state of the others. This is viewed as consistent with a sequential judgement process in which a perceiver searches for a significant starting point and then adjusts his provisional estimate in the light of the other information available to him.
