Aphantasia is the condition of reduced or absent voluntary imagery. So far, behavioural differences between aphantasics and non-aphantasics have hardly been studied as the base rate of those affected is quite low. The aim of the study was to examine if attentional guidance in aphantasics is impaired by their lack of visual imagery. In two visual search tasks, an already established one by Moriya (Attention, Perception, & Psychophysics, 80(5), 1127-1142, 2018) and a newly developed one, we examined whether aphantasics are primed less by their visual imagery than non-aphantasics. The sample in Study 1 consisted of 531 and the sample in Study 2 consisted of 325 age-matched pairs of aphantasics and non-aphantasics. Moriya’s Task was not capable of showing the expected effect, whereas the new developed task was. These results could mainly be attributed to different task characteristics. Therefore, a lack of attentional guidance through visual imagery in aphantasics can be assumed and interpreted as new evidence in the imagery debate, showing that mental images actually influence information processing and are not merely epiphenomena of propositional processing.

想象一下,您会发现–幻觉视觉影像缺乏注意力指导

幻觉症是自愿性影像减少或缺失的情况。到目前为止,由于受影响人群的基本比率很低,因此几乎没有研究幻觉行为者和非幻觉行为者之间的行为差​​异。这项研究的目的是要检查幻觉疗法中的注意力指导是否由于缺乏视觉形象而受到损害。在两项视觉搜索任务中,森谷已经建立了一项任务(注意力,知觉和心理物理学,第80页(5),1127-1142,2018)和一个新近开发的版本,我们研究了幻觉是否通过视觉图像进行灌注的程度比非幻象所致。研究1中的样本由531个组成,研究2中的样本由325个年龄匹配的幻影和非幻影对组成。Moriya的任务无法显示预期的效果,而新开发的任务却可以。这些结果可能主要归因于不同的任务特征。因此,在幻觉中通过视觉图像缺乏注意力指导可以被认为并解释为图像辩论中的新证据,表明心理图像实际上影响信息处理,而不仅仅是命题处理的现象。
