Hedonic arousal, time intervals, and excitation transfer

Zillmann’s (1978, 1983) excitation transfer theory was tested in relation to arousal processes opposite in hedonic valence. Sixty female subjects, randomly assigned to six experimental conditions, were initially exposed either to arousal stimulation positive in hedonic valence (sexual humor), or to arousal stimulation negative in hedonic valence (insulting remarks), or to a neutral unarousing task. In each condition, half of the subjects rated mildly arousing positively valenced male models’ photographs on several scales either immediately or with a 4 minute delay following prior arousal. In support of Zillmann’s theory, subjects in the positive hedonic arousal condition gave significantly lower photograph ratings on the arousal-related scales at the immediate, than at the delayed, rating time. However, contrary to Zillmann’s theory, the pattern of these ratings was reversed in the negative hedonic arousal condition, with the significantly higher ratings at the immediate, rather than delayed, rating time. Also, there were significant differences in these ratings among all three conditions both at the immediate and at the delayed rating time, but, as predicted, no significant differences were obtained for these ratings between the rating times in the control unarousing condition. The differences in excitation transfer between arousal processes positive and negative in hedonic valence may be due to their differences on a temporal dimension with regard to the speed of accumulation and the speed of dissipation of each arousal type.     

The effects of satiation and reinforcer develuation on signal-centered behavior in the rat

Two experiments are described which investigate the effects of satiation and reinforcer devaluation on signal-centered behavior in rats. In Experiment 1 lever contacts were established in hungry rats by pairing retractable lever presentations (CS) with response-independent food (UCS). Subsequently, food satiating these subjects significantly reduced the level of CS contact during an extinction test and, in particular, suppressed CS-directed licking and pawing. In Experiment 2 lever contacts which were established by lever-food pairings were suppressed when the food reinforcer was paired with lithium chloride (LiCl) induced illness. In particular, CS-directed licking, sniffing, and orienting were significantly suppressed by these food-LiCl pairings. These results suggest that signal-centered behavior (i) is not simply a manifestation of “conditioned hunger,” (ii) is determined to some extent by the animal's current need state, and (iii) is influenced by the status of specific reinforcer representations.     

The goal structure of situations

An empirical method for analysing the goal structure within and between persons in different social situations is described. The method involves establishing the main goals of occupants of situational roles and then finding out how the different goals inter-relate in terms of degree and type/direction of conflict and compatibility. Principal components analyses were carried out on ratings of importance of goals of those in different situational roles. Criteria of high factor loadings combined with high mean importance ratings were used to produce the main higher order goals for each of the roles. The goals for the six roles studied were, in each case except one: social acceptance/developing relationships, own well being and achieving a specific situational task goal. However, the precise nature of these goals is rather different in the different situations. Inter-relationship of goals was studied using ratings of conflict or compatibility between pairs of goals within and across roles of each situation. The results were used to describe the goal structures of the different situations. The situation with the most conflict between goals was, as expected, the complaint. Ways were suggested in which knowledge of the goal structure, particularly the points of conflict, could help with skilful handling of potentially difficult social situations.     

Word familiarity and retention

These experiments examine the relationship between subjects' familiarity judgements of words of similar (low) frequency and their recall or recognition of these words. The expected relationship between familiarity and recall was well confirmed, as was the less expected relationship between familiarity and recognition. An analysis of the vocabulary acquisition process led to more specific predictions about performance on delayed, as compared with immediate, retention tests. The most crucial of these predictions was that words which are familiar, but whose meanings are not known, are remembered by tagging sets of phonological (as opposed to semantic) features, leading to good immediate recall but poor delayed recall, and a greater likelihood of acoustic confusions following a delay. Some support was obtained for these predictions. However, subjects showed unexpectedly good retention of unknown words and it was felt that tagging alone does not account for all the findings.
