Awareness of intention je fenomenální zkušenost prožitku motorické intence, charakterizovaná jako vědomé uchopení akce, kterou se agent chystá provést. Typicky bývá ztotožňována s okamžikem, kdy si participant vzpomíná, že se rozhodl provést svou akci, reportovaným prostřednictvím pozice ručičky na ciferníku Libetových hodin. Intenzivní výzkum prožitku jednání (sense of agency) v posledních letech přinesl velké množství poznatků, ale také kritiku metodologických slabin, mezi které patří závislost výsledků na metodě reportování a závislost na arbitrárních vlastnostech reportovacích nástrojů. Filozofové si zase všímají intervenujících klamů vědomí či chyby Karteziánského divadla. Význačnou otázkou je také značná heterogenita experimentálních výsledků. Východiskem textu je argument, že mnohé z problémů tohoto výzkumného program souvisí se sadou implicitně zastávaných postojů, které vnímají awareness of intention jako integrovaný, unitární proces charakterizovaný graduálním nárůstem premotorické mozkové aktivity a náhlým nástupem uvědomění. Tato konceptuální východiska jsou převážně nereflektovaná, kontingentní a představují významné omezení pro explanaci současných empirických pozorování. Těžištěm článku je nástin nového teoretického rámce, který jde za implicitní předporozumění integrované perspektivy a umožňuje integrovat rozporné behaviorální výsledky. Tato rekonceptualice staví na Schoolerově teorii meta-uvědomění a teorii access a phenomenal consciousness Neda Blocka a nachází také oporu v neurovědných studiích. Představená rekonceptualizace přichází s dichotomií fenomenálního awareness of intention, souvisejícího s přípravou motorické intence v prefrontální oblasti a reflexivního meta-awareness of intention, které patrně souvisí s procesy v parietálním kortexu.

Awareness of intention is a phenomenal experience characterized as a conscious grasp of an action the agent is about to perform. Classically, it is identified with the moment the participant recalls deciding to move, as reported by the position of a hand on the Libet clock face. Booming research on the sense of agency produced significant knowledge but also a discussion of the methodological weaknesses, including a reliance on the experimental results on the reporting method and the arbitrary features of the reporting methods. Philosophers, on the other hand, discuss the intervening illusions and biases of consciousness or the Cartesian theater fallacy. A significant concern is the considerable heterogeneity of the experimental outcomes. A starting point for the present text is the argument that many of the issues of the research program at hand stem from the specific, implicitly held conceptualization. This implicit conceptualization understands awareness of intention as an integrated unitary process characterized by a gradual rise of premotor brain activity and sudden onset of the awareness. As I argue, this conceptual pre-understanding is mostly unreflected, contingent, and presents a significant limitation for the explanation of the empirical results currently dealt with. The text aims at outlining the new theoretical framework that goes beyond the present integrated perspective and permits to consolidate conflicting behavioral results. This reconceptualization builds upon Schooler’s theory of meta-awareness, the theory of access and phenomenal consciousness by Ned Block and also finds support in neuroscientific studies. The reconceptualization presented here introduces the dichotomy of phenomenal awareness of intention associated with the preparation of motor intention in the prefrontal cortex and a reflexive meta-awareness of intention that is likely linked to processes in the parietal cortex.
