While the general topic of agency has been collaboratively explored in philosophy and psychology, mental action seems to resist such an interdisciplinary research agenda. Since it is difficult to empirically access mental agency beyond externally measurable behavior, the topic is mainly treated philosophically. However, this has not prevented philosophers from substantiating their arguments with psychological findings, but predominantly with those which allegedly limit the scope and conscious controllability of mental action in favor of automated subpersonal processes. By contrast, the call (...) for a methodological extension through introspective access is particularly noticeable among proponents of a wider significance of mental action. Taking this up, it is shown how an empirical-introspective methodology can obtain a differentiated structure of mental activities occurring in directed thought. The empirical results gained under replicable conditions with 32 participants lead to insights about mental activity regarding (1) immanent causation, (2) content-free intention, (3) active receptivity and (4) its selective openness to mental content, and (5) different levels of observational awareness. These arguments speak for assigning an agentive status to the activities studied and hence for a more significant role of mental action in cognitive processes. (shrink)

Based on a short presentation of the unexplained relation of brain and consciousness, the mereological fallacy is addressed as a main point of criticism on typical, especially materialistic attempts of solution. Facing the risk of an unrefected mixing of different descriptive levels, purified phenomenologies of brain and consciousness have to be elaborated. Comparing the analytical results, not only incommensurable aspects but also superordinated structure factors can be shown which allow us to formulate a first featurebased relation. Because this interim result (...) does not disclose any evidence for a neurally based constitution of consciousness, an investigation of the structure-phenomenology of Herbert Witzenmann is embarked on as an intrinsic approach to consciousness research. Spurred on by cognitive borderline situations, this approach is motivated and elucidated referring to its method and outcome. Following its path, it becomes possible to interpret certain findings of neuroscience and systematic self-observation in the sense of cross-border effects and to establish a trans-categorical correlation in the context of logical constitution. This innovative concept of correlations is illustrated by aspects of rhythmicity, topology and plasticity. The attempt to position structure-phenomenology between monism and dualism leads to a dynamic integration of this polarity. Implications for human constitution and philosophy are sketched shortly. Finally, an outlook is given on possible projects of trans-disciplinary research. (shrink)
