Mood influences on automatic and controlled semantic priming.

Mood effects on automatic and controlled components of semantic priming were examined. After a neutral or positive mood manipulation, subjects underwent two blocks of a priming task. Automatic and strategic priming processes were operationally differentiated by the assumption that automatic priming remains constant during the task, whereas controlled priming develops slowly during the course of the experiment. In the first block the priming effect was greater for happy than for neutral mood participants. In the second block the priming effect was greater for neutral mood than for happy participants. The results confirm the hypothesis of a mood-dependent processing change: During early trials priming is based on automatic processing facilitated by positive mood. This processing mode is later superseded by controlled processes aided by neutral mood.

[Effect of mood and analytic and intuitive judgement tendencies in the "false-fame" effect].

In two experiments the process dissociation procedure (Jacoby, 1991) was used to examine the effects of mood on automatic and consciously controlled processes in a fame judgment task. Thirty nonfamous names were presented once in a study phase to the subjects. After a mood manipulation subjects performed a fame judgment task. The old nonfamous names were presented together with new nonfamous and famous names. Subjects got either the hint that names repeated from the study phase were all famous (inclusion test) or that they were all nonfamous (exclusion test). Results, especially the comparison of the inclusion and the exclusion test, indicated that subjects under negative mood based their judgments more on consciously controlled processes, i.e. recollection of names from the study phase. There was only a weak impact on good mood on controlled processes. In respect to automatic consequences of the study phase (familiarity of names) there was no difference between the three mood conditions.

[Effects of natural mood changes on discrimination performance and response trends in pattern recognition].

The effects of mood on thinking and behavior are characterized by "loosening" in the case of positive feeling states and "tightening" for negative ones (Fiedler, 1988). Style of cognitive processing, effort expenditure, and capacity models are discussed as explanatory concepts. To compare these approaches, the theory of signal detection provides methods for the independent evaluation of parameters of response bias and discrimination (and also efficiency). A laboratory experiment (Klauer et al., 1991) was replicated and supplemented by a field study. In the sense of convergent and discriminant validation of the insufficient techniques of mood induction, the naturally occurring mood changes of everyday life were used as mood manipulations. 13 subjects (M = 25.9 years of age, SD = 3.8) reported their feeling states on 18 days for self-selected episodes, which represented the range of their mood changes. Immediately after each mood report, they worked on a visual discrimination task. The indices of signal detection theory for response bias, discrimination, and efficiency were calculated in each cases, and correlated with measures of emotional and unspecific feeling states. Along with a shift from negative to positive feeling states, a trend towards a liberal response bias, a higher discrimination rate, and a greater efficiency resulted. Our findings replicate the laboratory experiment and support the effort expenditure and cognitive processing style view, rather than the reduced-capacity explanation. Speculations are offered concerning the emotional and cognitive processes which led to these results.

[Experimental induction of emotional conditions--alternatives to the Velten method].

The technique most often used to induce emotion is based on self-referent statements read by the subjects (Velten, 1968). This technique is known to be of intermediate efficiency. Therefore film and hypnosis-like procedures were investigated as alternative techniques. Efficiency was tested using two selected scales of a mood questionnaire (SES by Hampel, 1977). The subjects were male and female students. Both alternative procedures allowed us to induce significant changes in Ss' moods. The film method was more efficient than the Velten-technique in inducing a negative mood, whereas it was equally efficient in inducing a positive mood. The hypnosis-like procedure, however, was not more efficient than the Velten-technique. Obviously film is a quite efficient and easy applicable alternative technique to induce moods.
