The Role of Sketching States in the Stimulation of Idea Generation: An Eye Movement Study

We investigate the role of context in the comprehension of competing semantic representations of sentences with aspectual verbs (AspVs). On the Structured Individual Hypothesis, AspVs select for structured individuals as their complement, construed as a directed axis along various dimensions. During comprehension, the verb’s lexical functions are exhaustively retrieved and the AspV+complement composition yields multiple mutually exclusive dimension representations, which are later constrained by context. Results from this eye-movement study show that AspV sentences engender additional processing cost independent of context. That is, while processing multiple dimension representations is costly, the exhaustive lexical retrieval and dimension composition are initially encapsulated from context.

Movement Study

The current eye-movement study investigated whether a salient segmentation cue like the hyphen facilitates the identification of long and short compound words. The study was conducted in Finnish, where compound words exist in great abundance. The results showed that long hyphenated compounds (musiikki-ilta) are identified faster than concatenated ones (yllätystulos), but short hyphenated compounds (ilta-asu) are identified slower than their concatenated counterparts (kesäsää). This pattern of results is explained by the visual acuity principle ( Bertram & Hyönä, 2003 ): A long compound word does not fully fit in the foveal area, where visual acuity is at its best. Therefore, its identification begins with the access of the initial constituent and this sequential processing is facilitated by the hyphen. However, a short compound word fits in the foveal area, and consequently the hyphen slows down processing by encouraging sequential processing in cases where it is possible to extract and use information of the second constituent as well.

Sleep alterations after a 1-min exposure to ether vapor were studied in rats to determine if this stressor increases rapid eye-movement (REM) sleep as does an immobilization stressor. Ether exposure before light onset or dark onset was followed by significant increases in REM sleep starting ∼3–4 h later and lasting for several hours. Non-REM (NREM) sleep and electroencephalographic slow-wave activity during NREM sleep were not altered. Exposure to ether vapor elicited prolactin (Prl) secretion. REM sleep was not promoted after ether exposure in hypophysectomized rats. If the hypophysectomy was partial and the rats secreted Prl after ether exposure, then increases in REM sleep were observed. Intracerebroventricular administration of an antiserum to Prl decreased spontaneous REM sleep and inhibited ether exposure-induced REM sleep. The results indicate that a brief exposure to ether vapor is followed by increases in REM sleep if the Prl response associated with stress is unimpaired. This suggests that Prl, which is a previously documented REM sleep-promoting hormone, may contribute to the stimulation of REM sleep after ether exposure.
