Charles E. Osgood's theory of affective meaning defines affect as interplay of three meaning dimensions – evaluation, potency, and activity – that represent the central constituents of our affective ecology. Based on a rigorous Brunswikian sampling procedure, we selected a representative set of stimuli that mirror this ecology. A germane informative analysis explicates and corroborates the sampling approach. We then report two experiments testing whether these dimensions of affective meaning can be learnt by means of stimulus pairing and (...) class='Hi'>stimulus exposure. Our findings yield evidence for (1) stimulus pairing effects on evaluation and activity, and (2) stimulus exposure effects on potency and activity. Overall, the findings reveal that stimulus pairing and stimulus exposure differentially influence the learning of dimensions of affective meaning. We discuss implications of this research for current emotion theories as well as its contribution to research in the cognition–emotion interface. Finally, we argue that the implementation of representative design by virtue of Brunswikian sampling promotes theory development and opens new research avenues for an original and creative science of cognition and emotion.

The present commentary emphasizes that the acquisition of fear always involves complex changes in several quasi-independent response systems. Stimulus-specific electrodermal response differentiation as well as the bias to overestimate the belongingness of certain stimulus pairs mainly indicates cognitive processes of selective orienting and attention. Emotion, however, also involves the activation of subcortical motivational circuits. Why certain stimuli acquire rapid access to these basic motivational systems is not explained by the expectancy bias model.

Five experiments are reported that concern selective perception and representation following dichotic presentations of competing word pairs differing only in their initial consonants . Only one word from each pair tended to be subjectively perceived, even when participants were encouraged to guess two words. Robust selective perception effects were evidenced as a function of stimulus affective valence. Control tasks showed that these effects could not be attributed to report biases or to the acoustic properties of the stimuli. The (...) unreported words were not recognized on a two-alternative forced-choice task but were recognized with a more sensitive ranking task. Additional cognitive activity during the intertrial interval weakened memory only for the words reported as perceived. Moreover, negative affective valence decreased the recognition of words reported as consciously perceived but increased recognition of unreported words. The implications of these findings for theories of unconscious processing are discussed. (shrink)
