Abstract
The illustration that verbally comprehending the semantics of an item that convey a sense of brightness or darkness can trigger a pupillary light response offers a novel opportunity to study the focus of attention within verbal working memory. In doing so, the present paper hypothesized while an item that conveys a sense of luminance is at the focus of attention in a verbal working memory task, a pupillary light response should be observable in expected directions. A retro-cue paradigm was employed to isolate attention towards target items (bright vs dark-related), that are known to evoke a pupil light response. The task required the participants to judge whether a verbally cued item, retrieved from a verbal working memory sequence, rhymed or did not rhyme with another matched word. A 3s retention interval after cue onset was the window of interest as the target item should be at the focus of attention during this period. Analysis revealed that while the target items are in a prioritized state (i.e., focus of attention) within verbal working memory a pupillary light response is present. As such, the pupillary light response reveals the content of the attended in verbal working memory. This paper provides further support for previous research on verbal semantic comprehension while also extending similar observations in visual working memory of attention to the verbal domain.
