BACKGROUND
Research has suggested that depression is characterized by maintained attention for negative information.
METHODS
In this study, we examined whether maintained attention for emotional words influenced the attentional blink in a sample of stable dysphoric (n=14) and non-dysphoric (n=14) undergraduates. In a rapid serial visual presentation of white words, two green target words (T1, T2) had to be identified. If attention is maintained at negative information, T2 identification should be hampered by presenting a negative word at T1.
RESULTS
Results supported the hypothesis that negative words as T1 hampered the identification of T2 words if T2 was presented within 300 ms.
CONCLUSIONS
These results improve our understanding of the nature of attentional bias in dysphoria.
背景
研究表明，抑郁症的特征是对负面信息保持关注。
方法
在本研究中，我们在一组稳定的烦躁不安（n = 14）和非烦躁不安（n = 14）的本科生样本中，检验了对情感词汇的持续关注是否会影响注意瞬脱。在白色单词的快速序列视觉呈现中，必须识别两个绿色目标单词（T1、T2）。如果注意力保持在负面信息上，那么在T1呈现一个负面单词应该会妨碍T2的识别。
结果
结果支持了这样的假设，即如果T2在300毫秒内呈现，作为T1的负面单词会妨碍T2单词的识别。
结论
这些结果增进了我们对烦躁不安中注意偏向本质的理解。
