注意缺陷是精神分裂症核心症状中较为突出的表现。近期一项元分析表明，精神分裂症患者在内源性注意脱离方面存在缺陷。在本研究中，我们采用标准的空间线索范式，以探究此类患者的注意缺陷究竟是源于注意脱离受损，还是新奇性检测/习惯化过程存在缺陷。在一项采用外周非预测性线索及检测任务的空间线索程序中，我们在两个独立实验里分别对线索或目标（即威胁性面孔与打乱的面孔）的效价进行了操控。对照组仅在目标带有情绪负荷时，表现出较小的返回抑制（IOR）效应，而当线索带有情绪负荷时则无此现象。在患者组中，当威胁性面孔作为目标时，出现了较大的情绪效应；相反，当威胁性面孔作为线索时，未观察到效价的影响：无论效价如何，IOR均延迟或完全缺失。本研究结果与IOR源于注意脱离及随后的返回抑制这一假设相悖。相反，这些结果似乎表明，在先前提示过的位置检测新信息存在代价。从这个角度来看，精神分裂症患者似乎在检测新信息并将其视为当前情境中的新信息方面存在缺陷。
Attention deficits are prominent among the core symptoms of schizophrenia. A recent meta-analysis has suggested that patients with schizophrenia have a deficit in endogenous disengagement of attention. In this research, we used a standard spatial cueing paradigm to examine whether the attention deficit of such patients is due to impaired attentional disengagement or defective novelty detection/habituation processes. In a spatial cueing procedure with peripheral non-predictive cues and a detection task, we manipulated the valence of either the cue or the target (i.e., a threatening vs. scrambled face) in two separate experiments. The control group exhibited a smaller inhibition of return (IOR) effect only when the target had an emotional load, not when the cue had an emotional load. In the patient group, a larger emotional effect appeared when the threatening face was the target; by contrast, no effect of valence was observed when the threatening face was the cue: IOR was delayed or completely absent independently of valence. The present findings are in conflict with the hypothesis that IOR is due to the disengagement of attention and the subsequent inhibition to return. Instead, they seem to suggest a cost in detecting new information at a previously cued location. From this perspective, it seems that patients with schizophrenia might have a deficit in detecting new information and considering it as new in the current context.
