作者检验了这样一个假设：威胁相关信息的激活和抑制异常可能是社交焦虑中信息处理偏差的原因。患有广泛性社交恐惧症（GSP）和非焦虑对照的个体被呈现以同形异义词和非同形异义词结尾的句子，并被要求对每个句子后面的提示词做出决定。一半的同形异义词具有社会威胁含义。与以非同形异义词结尾的句子相比，对以同形异义词结尾的句子做出决定的响应延迟更长，这被认为反映了同形异义词的不适当含义的激活。结果显示，GSP 最初激活了社会相关同形异义词的不适当含义，随后又抑制了这些含义。这些发现与社交恐惧症中威胁相关信息的信息处理的警惕避免模型一致。
The authors examined the hypothesis that abnormalities in activation and inhibition of threat-relevant information may account for information-processing biases in social anxiety. Individuals with generalized social phobia (GSP) and nonanxious controls were presented with sentences ending in homographs and in nonhomographs and were asked to make decisions about a cue word that followed each sentence. Half of the homographs had a social-threat implication. Longer response latency to make decisions about sentences ending in homographs compared with sentences ending in nonhomographs is thought to reflect activation of the inappropriate meaning of the homographs. Results revealed that GSPs showed initial activation of inappropriate meanings of socially relevant homographs followed by later inhibition of these meanings. These findings are consistent with a vigilance-avoidance model of information processing of threat-relevant information in social phobia.
