Emergence times, from the home cage and from the start-box of a runway, were measured in testosterone-injected and oil-injected chicks. Hormone treated birds took longer to emerge, a result which could not be explained in terms of earlier findings that testosterone decreased emotional responsiveness in novel environments. An attentional explanation is suggested, and the limitation of emergence tests for measuring fear is pointed out. © 1976.
