Territorial cichlids were presented for 30 min with a conspecific male intruder (contained in a clear glass tube). Eight hr prior, 2 groups were administered alcohol (0.15 or 0.30 percent in the aquaria water). A third group served as a control. Three responses were recorded to allow analysis of topographic changes in behavior as well as changes in absolute levels. During the habituation phase, the normal group showed a sequence of long displays, followed by shorter ones as the frequency of attacks increased. The occurrence of threat which gradually gives way to attack is characteristic of the agonistic behavior of this species. In contrast to the controls, the 0.15 percent group was hyperaggressive, while the 0.30 percent group was hypoaggressive. Furthermore, the patterning of responses were abnormal. The 0.15 percent group gave abbreviated threats and more attacks (interpreted as a tendency to attack without warning); whereas, the 0.30 percent group gave many long threat displays, but few attacks. A stimulus specificity test provided strong evidence that the waning found during the initial phase was habituation.
将领地性丽鱼科鱼与一只同种雄性入侵者（置于透明玻璃管中）放在一起30分钟。8小时前，两组鱼被给予酒精（水族箱水中含0.15%或0.30%）。第三组作为对照。记录了三种反应，以便分析行为的形态变化以及绝对水平的变化。在习惯化阶段，正常组表现出一系列长时间的展示，随着攻击频率增加，随后展示时间变短。威胁的出现逐渐让位于攻击，这是该物种争斗行为的特征。与对照组相比，0.15%组具有过度攻击性，而0.30%组具有低攻击性。此外，反应模式异常。0.15%组发出简短的威胁并进行更多攻击（被解释为无预警攻击的倾向）；而0.30%组发出许多长时间的威胁展示，但很少攻击。一项刺激特异性测试提供了有力证据，表明在初始阶段发现的减弱是习惯化。
