A substantial portion of the knowledge base of psychology is based on subjective reports with a risk of information bias. The objective of the present study was to elucidate one contextual source of variance and potential bias in subjective reports: the influence of affective state at the time of responding to questionnaires. Employees were subjected to mood-induction procedures in the laboratory. Neutral, positive, and negative moods were induced by combinations of pictures from the international affective picture set and music. The (...) subjects responded to questions on visual analog scales in order to optimize sensitivity and attenuate short-term memory effects. Most subjects exhibited significant affective-state inductions with no change in arousal. The analyses took affective response to the manipulation into account. Only four of 20 questions were somewhat influenced by induced affective state: job overload, social support from co-workers, satisfaction with getting to develop personally, and an item measuring agreeableness. In general, responding to questions of work that were phrased for valence was little or insignificantly influenced by induced affective state. (shrink)

There is a speed-accuracy trade-off in perception. The ability to quickly extract sensory information is critical for survival, while extended processing can improve our accuracy. It has been suggested that emotions can change our style of processing, but their influence on processing speed is not yet clear. In three experiments, combining online and laboratory studies with different emotion induction procedures, we investigated the influence of both affective states, manipulated with music, and individual traits in sensory-processing sensitivity on the ability to (...) rapidly segregate two visual flashes. Across studies, the musical manipulations pushed participants towards either rapid or slow processing. Individual variations in sensory-processing sensitivity modulated these effects. Our findings demonstrate that affective states, influenced by music, can shift the balance between fast and slow visual processing, altering our perceptual experience. These results also emphasise the interaction of individual traits in sensory processing and affective states. (shrink)
