Experimental group members watched a fish aquarium or a fish videotape, while control group members viewed a placebo videotape. Three eight-minute treatment sessions were held one week apart. Members of all three groups perceived their treatments as relaxing. Aquarium observers tended to experience a decrease in pulse rate and muscle tension and an increase in skin temperature. Theoretical and practical implications of the results and ideas for further research are discussed.
