Rats were injected with chlordiazepoxide 30 min before a situation of uncontrollable stress, or 30 min before an FR-3 escape test 24 h after the uncontrollable stress. Only in the latter situation they reduced their response latencies. The conclusion was that helplessness after moderate stress (i.e. electric shock) resembles a state of anxiety. Anxiety can be described on a behavioural level as inhibiting the ongoing behaviour. Therefore an explanation in terms of anxiety is in agreement with Weiss' inactivity hypothesis and with the results of the study by Drugan et al., who also emphasized the role of anxiety or fear in learned helplessness experiments.
在不可控应激情况前30分钟给大鼠注射氯氮卓，或在不可控应激24小时后的FR-3逃避测试前30分钟注射氯氮卓。只有在后一种情况下，它们才缩短了反应潜伏期。结论是，中度应激（即电击）后的无助感类似于焦虑状态。焦虑在行为层面上可被描述为抑制正在进行的行为。因此，从焦虑角度的解释与韦斯的不活动假说相符，也与德鲁根等人的研究结果相符，他们也强调了焦虑或恐惧在习得性无助实验中的作用。
