- Effects of thinking training using graphical representations on spatial intelligence and its objective evaluation
Sugio Takeshi
The present study sought to determine what visual attributes are associated with global reading, whether it is possible to determine from objective measures such as eye movements that global reading is taking place, and the neural basis of semantic processing for graphical representations. The results revealed that global reading dominated when the multiple visual attributes that make up the graphical representation evoke common emotions among each other. Next, it was shown that differences in the extent of attention to visual stimuli can be quantified by an index derived from eye movement patterns. Finally, fMRI experiments revealed that semantic processing for graphical representations occurs in the left inferior parietal lobule., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2019/04 -2022/03, Grant-in-Aid for Scientific Research (C), Doshisha University - An integrated approach to the processing of abstract information in diagrammatic reasoning
Shimojima Atsushi
We studied the abstract information processing in diagrammatic reasoning by combining a logical, computational, and psychological approach. Under the logical approach, we showed that structurally diverse diagrammatic representations such as numerical graphs, connection diagrams, and tabular representations have a common semantic mechanism. We used this finding to give a general explanation for why many diagrams can exhibit abstract information in a flexible manner. Under the computational approach, we applied a proof-theoretic method to analyze the exchange of information in heterogenous proofs that use both sentences and diagrams, and thus pioneered a mathematical way to elucidate abstract information processing in diagrammatic reasoning. Under the psychological approach, we clarified the neurological mechanism and the attentional characteristics of global reading of diagrams, which is the quintessential process of extracting abstract information from diagrams., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2015/04 -2020/03, Grant-in-Aid for Scientific Research (B), Doshisha University - The role of executive function in the flexible reading of the diagrams
Sugio Takeshi
Reading a diagram in a flexible manner requires the utilization of the conventional knowledge about the diagram for deriving its meaning. In the present study, we investigated how both visual attention and cognitive control are involved in the perception and the cognition of the diagrams at both a global and a local level. In addition, we explored the neural mechanisms of global reading of the diagrams by using fMRI. As a result, we found that the category-specific knowledge of the diagrams indeed influenced both the global and the local processing of the diagrams. Moreover, the brain activation showed that inhibitory control was involved in the global processing of the diagrams. These results suggest that the role of conventional knowledge in the flexible reading of the diagrams, and it is necessary to consider how to apply such principle to a diagram design., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2015/04 -2018/03, Grant-in-Aid for Scientific Research (C), Doshisha University - Neural basis of interactive cognitive control: Common underlying mechanisms and individual differences

We conducted 5 research projects to elucidate the determinants of individual differences in cognitive control, and to investigate the role of cognitive control in behavior control, working memory, pattern recognition, and visual awareness. Projects on mind wandering, visual working memory, diagram understanding, and binocular rivalry revealed various interactions between task specific brain regions (default mode network [DMN], parietal lobe, higher visual areas, etc.) and prefrontal regions, using fMRI, EEG, and tDCS techniques. A project on individual differences in cognitive control revealed the effects of genetic polymorphisms related to dopamine and acetylcholine functions on both behavioral interference in MSIT task, and on the pattern of functional connectivity among brain regions., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2012/04 -2016/03, Grant-in-Aid for Scientific Research (A), Kyoto University - Integrated Study of the Competence of Diagrammatic Representation Systems and the Performance of Diagrammatic Reasoning
SHIMOJIMA Atsushi; SUGIO Takeshi; KATAGIRI Yasuhiro; TAKEMURA Ryo
The purpose of this study is to predict, on the basis of logical analysis of its semantic properties, what cognitive competences a diagrammatic system has, and to verify, on the basis of psychological experimentation, how those competences affect the actual processes of human reasoning. In particular, we have applied this integrated method to the systems of iconic tables, and analyzed the expression and comprehension of abstract information based on the visual properties of the row and column level, as well as the automatic expression and comprehension of logical consequences based on incremental expression of information to tabular representations., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2011 -2013, Grant-in-Aid for Scientific Research (B), Doshisha University - 物体認識における感覚運動系の役割

In this research task, the new domain of the data science about cultural properties was exploited. In particular about cultural properties, various researches were not progressing in the field until now. The distinctive character of cultural-properties data was investigated, that database was developed, and analysis of the cultural phenomenon was carried out by this project. STIS (Spatio-Temporal Information System) which unifies various information were developed and various phenomenon analysis modules were implemented.Also Our project held international symposium in the last fiscal year, advanced the share in question, and exhibited the result., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2006 -2009, Grant-in-Aid for Scientific Research (A), Doshisha University - Investigation on the internal representation of interaction processing using multiple approach

Interactions between hand movements and visual feedback are investigated. Results suggest that the central nervous system controls movements based on the prediction or the estimation of consequent motor accuracy taking into account both sensory and motor error. It is also suggested that the pre-supplementary motor area (pre-SMA), the right posterior parietal cortex (PPC), and the right temporo-parietal junction (TPJ) are involved in internal movement prediction, online evaluation of visuomotor error, and movement estimation to compensate for visual feedback delay, respectively. Experiments on cross-modal integration between vision and haptics with dynamic objects revealed that representation of dynamics as a weighted linear summation of sensory cues mediates cross-modal integration, and that temporal cues used in integration is independent of those used in simultaneity judgments. Experiments on cross-modal object recognition showed that recognition of 3-D objects within single modality utilized both viewpoint-dependent and viewpoint-invariant information, whereas object recognition by a modality not used in learning exclusively utilized viewpoint-invariant information. It was found that the motor program for a familiar object is highly activated during the execution of the action in conventional manner, while the role of visual feedback is more dominant for an unfamiliar action. These results suggest that the motor representation for a familiar object is based on the previous interactions between the part of the object to be grasped and a particular hand shape. It was experimentally shown that active exploration of object views using a track ball facilitates object recognition. It suggested that a rule for view transformation of objects was learned by the interaction between information provided by hand movements from the motor system and visual information. Moreover, it was demonstrated that active exploration leads to a significant decrease of the amplitude of the magnetic field in the left hemisphere at the time period when the current dipole was estimated in the left parietal cortex., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2004 -2007, Grant-in-Aid for Scientific Research (A), Kyoto University - Measurement of colored-hearing synesthesia-Non-verbal mapping between sound and color-

(1)Brain activity in colored-hearing synesthetes when listening to music : an fMRI study We measured brain activity in colored-hearing (musical tonality-color ) synesthesia, in which a person sees colors when listening to music, by using functional magnetic resonance imaging (fMRI). We compared the images acquired from two colored-hearing subjects and 11 non-colored-hearing subjects when listening to various kinds of music. The results showed that the fusiform gyrus, cerebellum, right lateral inferior parietal lobule and superior frontal gyrus were activated only in the colored-hearing synesthetes. Moreover we found that the area of activity in the cerebellum and the color area, V4/V8 (V4 complex), in the fusiform gyrus which was also activated, are next to each other, and were activated coincidently. It indicates that colored-hearing synesthetes actually perceive colors when listening to music and that they experience a direct interaction between the auditory and visual modalities. In addition, this suggests evidence for the synesthesia cross-wiring hypothesis that there is a strong neurological connection between the color V4 complex and the cerebellum, and that the activity in the V4 complex occurs as a result of the activity of the cerebellum caused by listening to music. (2)Interactions between pictures and music in TV commercials- We presented an analysis of the relationship between the elements of pictures and music which make up commercials. In order to clarify the interactions between the expressions of pictures and music, the expressions were classified into 9 elements, 71categories. These categories were applied to commercial samples using Hayashi's Quantification Theory III. The result shows picture and music elements contribute greatly to the impression such as Exciting-Calm and Homely-Sophisticated made by commercial. We have been also successful in clarifying the relationship between basic elements such as color tone and tonality, indicating the probability of their appeal to the subconscious feelings of human beings., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2005 -2006, Grant-in-Aid for Scientific Research (C), Kwansei Gakuin University - 操作的動作の運動イメージに基づいた物体認識メカニズムに関する研究

道具などの日常物体を把持するときに無意識的に取っ手に対して手を伸ばす現象は,道具を構成している部分間の3次元的な構造に関する知識と,道具をどのように使用したらよいかに関する知識の統合が脳内で行われていることを示唆している.こうした統合メカニズムを明らかにすることは,物体に対する操作的動作の知識が物体認識において果たす役割を解明する上で重要であるといえる.本年度は,こうした統合過程の脳内基盤に関する検討を行った.日常的な物体に対する把持と関連した構造特性として,大局的な伸長性と局所的な特徴があげられる.実験では,これら2種類の特性がそれぞれ異なる4種類の物体(ハンマー,定規マグカップ,小ボトル)の画像を用いて,到達把持運動のイメージ化課題を行った.事象関連型fMRIによって脳活動の計測を行い,4種類の物体で共通した活動がみられた脳内領野を結合解析によって検討した後,物体の違いによる活動の変調を検討するためにROI解析を行った.その結果,両側の視覚関連領野,左優位の頭頂皮質から中心前回にかけての領野,そして右優位で小脳に活動がみられた.これらの領野の活動は先行研究と一致するものであった.さらに,ROI解析の結果,把持に関連した頭頂間溝前外側領野(AIP)ではマグカップのみが有意に高く,到達に関連した頭頂間溝内側領野(MIP)や上頭頂小葉(SPL)では小ボトルの活動が他の3つよりも有意に低かった.これらの結果は,いずれも運動計画における自由度と関係していると考えられる.把持を行う物体の位置と手の形状に関する自由度が物体の構造知識と意味知識から検索され,到達把持運動における自由度が決定される.後部頭頂皮質はこうした過程に関与していることが示唆された., 日本学術振興会, 科学研究費助成事業, 2003 -2004, 若手研究(B), 京都大学 - Mechanisms of information integration between dorsal and ventral visual systems in human

Inui and Konishis' report: We measured the activity of the brain during using chopsticks, observing, imaging the use of them, and performing the use of them by pantomime. As a result, we found that inferior parietal lobe, which is assumed to operate the memory representation of actions, is related to these performances. It also appeared during executing these actions, right PMv is related to the precise adjustment of the movement. On the other hand, we examined the kinds of visual information which plays an important role in the motor control of grasping movement. As a result, we found that visual information between 150ms and 350ms after the movement onset is important especially for the motor control in which the movement duration is fixed at around 1,100ms. Our results emphasized the relevance of the time to record the maximum speed, approximately 350ms after the start of movement. Saiki's report: We conducted the experiments of MOPT tasks using objects that are defined with colors and shapes. Our results show that three to four combinations of colors and shapes cannot be retained at the sue time. It was revealed that three to four object representations, each of which is processed and integrated through the dorsal and ventral pathways, are not retained in the brain at a given time. Rather, we found that we can retain only the limited numbers of object representations, repeatedly and dynamically constructing and deconstructing them through the feature integration process by the selective attention. Sugio's report: We investigated the effects of local features and familiarity of everyday objects on hand shaping control of grasping by the event-related fMRI studies. Our results indicated that hand shapes of grasping the object with handle parts depended on the motor scheme activated by both semantic knowledge and local graspable features. Hayashi's report: We measured the latency of the saccadic eye movement when the position of the target object unexpectedly changed during reaching and grasping movement. The average latency over six subjects were 258±35ms in actually reaching and grasping, and 323±40ms in only fixating. This meant that the latency became short due to the execution of reaching and grasping. Suggested that the degree of the focus of visual attention would be positively correlated with the saccadic latency, this could predict that attention may be easily disengaged in early period of reaching and grasping control., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1999 -2002, Grant-in-Aid for Scientific Research (A), KYOTO UNIVERSITY - 行為理解における感覚運動系の役割
