People can automatically perceive the color diversity of an unattended visual display without sacrificing their ability to report a cued letter. This finding suggests that detailed visual information, such as the variety of colors, is registered outside focal attention and does not consume working memory resources. The result supports the idea that visual experience may overflow what can be reported, offering a way to study phenomenal consciousness without relying solely on limited-capacity report.
The Unfolding Argument (UA) against causal structure theories of consciousness relies on unwarranted assumptions that express a behaviorist methodology, despite its proponents' claims. The same reasoning can be applied to functionalist approaches, proving too much and deeming a wide range of non-causal structure theories unscientific. The authors argue that the UA's philosophical assumptions are overly restrictive and fit poorly with common practice in cognitive neuroscience. They propose a more inclusive methodology for consciousness science that incorporates neural, behavioral, and phenomenological evidence from the first-person perspective. Theories of consciousness should be tested and evaluated on humans, not on systems considerably different from us, thus restricting the range of systems rather than the methodology.
