ECs are a key to elucidating the computational system of syntax, algorithms of language processing, and their neural implementation. Here we examined the distinction between raising and control sentences in Japanese and whether ECs are psychologically real. Methods: We recruited 254 native speakers of Japanese in the present internet-based experiment. We used a self-paced reading and a probe recognition priming technique. To investigate whether raising and control sentences have different ECs (i.e., Copy and PRO) and whether these ECs cause a reactivation effect, behavioral data were analyzed using linear mixed-effects models. Results: We found two striking results. First, we demonstrate that the reading times of raising and control sentences in Japanese were better explained by the linear mixed-effects model considering the differences of ECs, i.e., Copy and PRO. Secondly, we found a significant reactivation effect for raising and control sentences, which have ECs, and reflexive sentences without ECs. These results indicate that ECs are processed similarly to reflexive pronouns (e.g., himself ). Discussion: Based on these results, we conclude that raising and control sentences in Japanese have different ECs, i.e., Copy and PRO, and that ECs have psychological reality. Our results demonstrate that behavioral experiment based on theoretical linguistics, which is the first step for developing linking hypotheses connecting theoretical linguistics and experimental neuroscience, is indeed necessary for testing hypotheses proposed in theoretical linguistics.. |
| 2. | 太田真理, 岩下千咲, 子音の音韻素性がオノマトペの音象徴に与える影響：SD法と因子分析を用いた研究, 音韻研究, 26, 43-50, 2023.03, Previous studies on sound symbolism of Japanese onomatopoeia have reported that the phonological feature [±voice] of a word-onset consonant causes contrastive meanings/impressions. However, whether or not [±voice] of word-internal consonants, as well as other phonological features, produces different meanings/impressions has remained unclear. Using semantic differential and factor analysis on Japanese onomatopoeic words, we examined the effects of word-internal consonants, as well as of word-onset consonants, on sound symbolism. We replicated previous findings, showing that the phonological feature [±voice] of the word-onset consonants caused sound symbolism related to psychological state (e.g. tense/relaxed), movement (e.g. heavy/light), shape (e.g. large/small), and sound (e.g. noisy/quiet). We also found for the first time that [±voice] of the word-internal consonants made contrastive meanings/impressions related to movement, shape, and sound. Furthermore, [±sonorant] of both word-onset and word-internal consonants caused sound symbolism of the onomatopoeia related to psychological state and sound. Our results demonstrate that the phonological features of [±voice] and [±sonorant], which produce contrastive meanings/impressions, are crucial for sound symbolism in onomatopoeia.. |

However, the necessity of the PPC in executive functions has been questioned. The present study used the stop-signal task to examine response inhibition, an executive function that inhibits prepotent response tendency. The brain activity and resting-state functional connectivity were measured to analyze a parcellation-based network that was aimed at identifying a candidate PPC region essential for response inhibition in humans. The intraparietal sulcus (IPS) was activated during response inhibition and connected with the inferior frontal cortex and the presupplementary motor area, the two frontal regions known to be necessary for response inhibition. Next, transcranial magnetic stimulation (TMS) was used to test the essential role of the IPS region for response inhibition. TMS over the IPS region prolonged the stop-signal reaction time (SSRT), the standard behavioral index used to evaluate stopping performance, when stimulation was applied 30–0 ms before stopping. On the contrary, stimulation over the temporoparietal junction region, an area activated during response inhibition but lacking connectivity with the two frontal regions, did not show changes in SSRT. These results indicate that the IPS identified using the parcellation-based network plays an essential role in executive functions.. |
