Biases in the interpretation of ambiguous information may have a causal role in producing and maintaining anxiety. Training with repeated exposure to emotionally valenced meanings has been found to produce such a bias, as measured by lexical decisions for targets primed with related emotionally ambiguous homographs. Interpretation bias is thought to occur only when ambiguity causes competition for processing resources, but similar results might occur if valenced training causes a response bias. Twenty participants underwent training, followed by a lexical decision task with no ambiguous primes preceding the target stimuli. No training effect was found, supporting the resource competition explanation for the previous findings.
对模糊信息的解释偏差可能在焦虑的产生和维持中起因果作用。通过对与情感相关的模糊同形异义词引发的目标进行词汇判断来衡量，反复接触情感效价意义的训练已被发现会产生这种偏差。解释偏差被认为仅在模糊性导致处理资源竞争时才会发生，但如果效价训练导致反应偏差，可能会出现类似的结果。20名参与者接受了训练，随后进行了一项词汇判断任务，在目标刺激之前没有模糊的启动词。未发现训练效果，这支持了对先前研究结果的资源竞争解释。
