Evidence of sleep-facilitating effect on formation of novel semantic associations: An event-related potential (ERP) study

Reactive control in evaluating appropriately or inappropriately novel ideas: Evidence from electrophysiological measures

“…First, perceptual conflicts between externally given solutions (strokes) and internally generated ideas (radicals) will certainly lead to semantic conflicts because the radicals convey phonological and semantic information of characters (Zou et al, 2019). Although the classical N400 component tends to have a centroparietal scalp distribution (Lau et al, 2014), it is sensitive to semantic violations in appreciating novel words (Bakker et al, 2015), novel compound words (Kaczer et al, 2015), novel associations (Lin & Yang, 2014), and novel metaphors (Obert et al, 2018). Second, Chinese characters are typical hieroglyphs, and compared with radical‐level decomposition, stroke‐level decomposition breaks the orthographic rules of characters to a greater extent.…”

A daily diary study on maladaptive daydreaming, mind wandering, and sleep disturbances: Examining within-person and between-persons relations

“…One possible explanation for this distinction is that poor sleep temporarily reduces executive cognitive control, which according to the cognitive failures hypothesis would reduce people’s ability to prevent the mind from wandering [cf., the cognitive failures hypothesis of mind wandering; 34]. Another speculative possibility is that poor sleep leads to lower functional connectivity [35, 36] and greater independence of semantic networks and generation of novel associations [37], which could lead to greater decoherence in the stream-of-consciousness—thus increasing the frequency of mind wandering episodes. Maladaptive daydreaming, on the other hand, may involve a narrower focus of attention, and therefore demand a higher degree of cognitive control and coherence than mind wandering.…”

Newly-acquired words are more phonologically robust in verbal short-term memory when they have associated semantic representations

“…Ho e e , the stud s design might have restricted sensitivity to semantic effects, since there was a small set of items for each condition (N=10) and each condition was tested separately; thus the ISR test was characterised by massed repetition. Lexical and semantic effects on ISR are strongest in open sets of non-repeated items (Jefferies et al, 2004;Roodenrys & Quinlan, 2000) Lin & Yang, 2014;Tamminen & Gaskell, 2013 To examine whether semantic information increases the stability of the phonological trace, independently of phonological familiarity, we considered 1) if nonwords trained with a semantic association would have higher stability than nonwords trained without meaning -i.e., if more whole items would be correctly recalled and if there would be fewer phoneme ordering errors in ISR following semantic training -and 2) if lexical or semantic effects on phonological coherence would be apparent in ISR from the day of training, or if they would emerge more strongly on the subsequent day. We used a phonological familiarisation procedure developed by Savill, Ashton, et al (2015), in which 48 novel phonological forms were paired with either pictures of objects (in the semantically-trained condition; SEM) or blurred images in which there were no discernible features (in the no semantics condition; FAM).…”
