Aggressive motivation in Betta splendens: Replication and extension

Abstract

In two experiments with male Ss, mirrors were more effective than live male fish in eliciting aggressive displays; Ss displayed less frequently but spent more time viewing both stimuli during continued or repeated exposure to them. Presence of a female Betta decreased display frequency to mirror but did not affect display frequency to male. Responsiveness to live fish was more consistent than that to mirrors. © 1969, Psychonomic Journals, Inc.. All rights reserved.
