Dimensions of information processing: physiological reactions to motion pictures

Information processing is studied using physiological reactions to motion pictures as a major tool. In study I (N=44) physiological reactions are subjected to multivariate analysis revealing three major dimensions: familiarization, effort, and readiness (cf. Pribram and McGuinness, 1992). Each dimension contrasts controlled processing with automatic processing. In study II (N=72) and study III (N=96) the dimensions are tested. In those studies specific information is provided prior to film onset and the effects on the physiological reactions are studied. The results generally confirm the model. Study IV (N=44) is concerned with individual differences in information processing. Reactions to seven films are analysed with generalizability for each dimension separately. The results show that individual dimension scores are highly consistent across different situations. In the discussion it is argued that the three information processing dimensions identified here can be conceived as stable personality dispositions, underlying individual differences in learning and overt behaviour.
