| Outline of Final Research Achievements |
First, I showed that the potentiation of the pupil-linked neuromodulatory system and the more forceful motor actions occurred regardless of whether the goal-priming words were fully visible or not. This indicates that conscious awareness of behavioural goal-priming is not a necessary condition for goal pursuit processes to recruit resources for motor action. This in turn suggests that the implicit motivation effect, which is induced by an association between physical exertion and positive affect, underlies motor-goal priming and acts as a reward signal.
Next, I observed a trend that when combined with the term maximal in the consciously visible form, the effect of such subliminal motor-goal priming was abolished without conscious awareness. This is important because I hypothesise that the behavioural goal of maximal voluntary contraction (MVC), namely maximal voluntary force exertion, may unconsciously prevent goal pursuit, contributing to the inhibitory mechanism underlying MVC.

| Academic Significance and Societal Importance of the Research Achievements |
（古典的条件付けパラダイムの）無自覚的動機づけの運動促進効果は、その条件刺激（運動の概念を持った語彙）の見え方の意識的な知覚の有無に関係なく確認された。これは、閾下プライミングにおける「被験者がプライムに気づいているのではないか」との疑念を払しょくできた点で意義深い。
また、この高い信頼性が担保された暗示的連合学習を用いた、仮説「最大筋力（MVC）発揮時に働くと考えられている抑制因子がMVC時の『最大筋力の発揮』の行動目標自体に内在する」の実証と心理的限界解明の試みは、競技力向上を目指したスポーツ選手のみならず、筋機能改善を目指した中高齢者やリハビリテーション患者にも大いに役立つと考えられる。
