The aim of this study was to clarify how the sense of heaviness changes our cognition. According to recent studies in cognitive science, intelligent human behaviors ranging from perception to inference are not closed mental processes; rather, they are affected by body and action (Wilson, 2002; Gibbs, 2005; Proffitt, 2006). In previous studies, the sense of heaviness activated concepts metaphorically related to heaviness, and changed impressions accordingly. However, previous studies have not distinguished between subjective heaviness and physical weight. The purpose of this study was to clarify whether changes in impressions are due to subjective heaviness or physical weight. To examine this issue, a psychological experiment using a tasting task was conducted. The results confirmed that subjective heaviness influences evaluations of price and value.

Acceptability Rating Data for Japanese (ARDJ) is a project that explores the true nature of acceptability judgement basedon a large-scale survey using theoretically unbiased stimuli. Its main survey was carried out in 2018 in two phases withcarefully constructed 300 stimulus sentences: Phrase 1 was a smaller scale experiment with roughly 300 college students;Phase 2 was a large scale web survey with over 1,600 participants.This paper reports on phase 2 and provides two results: Analysis 1 brought us a good typology of 300 sentences; Analysis2 implements explicit modeling of acceptability judgement using Semi-supervised local Fisher discriminant analysis.The results, if combined, suggest that i) acceptability is not a simple dichotomous partitioning of stimuli; ii) acceptabilityis a complex property that emerges through an interplay among the three factors: 1) degree or strength of deviance, 2)syntactic and/or semantic complexity of stimulus, and 3) localizability of deviance.
