| Outline of Final Research Achievements |
The purpose of this study is to evaluate an implicit influence of spatial frequency on neural activities and scan path on eye movement, in humans.
An experiment was conducted where the electroencephalogram recordings of individuals, while they executed an implicit association task, was studied. This allowed for the detection of implicit biases of the subjects. The result showed a relationship between spatial frequency and neural activity; high frequency, particularly, seemed to affect the activities in the parahippocampal gyrus. Additionally, we conducted a visual image search task controlled by spatial frequency, and the scan path was analyzed using a convolutional neural network. During this task, a subconscious search may have occurred, but the subjects were unable to locate the target.

| Academic Significance and Societal Importance of the Research Achievements |
研究の成果より，空間周波数といった視覚デザインとして目立たない特性が，何かを探索する際の観察者の視線応答に潜在的な影響を与え，例えば探索物を見つけやすくなる等の可能性が示唆された．また潜在的な活動における大脳神経活動についての知見も得られた．
このため，建築デザイン，工業デザイン，映像コンテンツ等の視覚的な構成物に，空間周波数特性を利用することにより，ユーザが使いやすく，人間の自然な感覚に従う人にやさしいデザインといった新たな付加価値を与えるものと期待できる．
