This article reports four subliminal perception experiments using the relationship between confidence and accuracy to assess awareness. Subjects discriminated among stimuli and indicated their confidence in each discrimination response. Subjects were classified as being aware of the stimuli if their confidence judgments predicted accuracy and as being unaware if they did not. In the first experiment, confidence predicted accuracy even at stimulus durations so brief that subjects claimed to be performing at chance. This finding indicates that subjects's claims that they (...) are ''just guessing'' should not be accepted as sufficient evidence that they are completely unaware of the stimuli. Experiments 2-4 tested directly for subliminal perception by comparing the minimum exposure duration needed for better than chance discrimination performance against the minimum needed for confidence to predict accuracy. The latter durations were slightly but significantly longer, suggesting that under certain circumstances people can make perceptual discriminations even though the information that was used to make those discriminations is not consciously available.

Contemporary studies in unconscious cognition are essentially founded on dissociation, i.e., on how it dissociates with respect to conscious mental processes and representations. This is claimed to be in so many and diverse ways that one is often lost in dissociation. In order to reduce this state of confusion we here carry out two major tasks: based on the central distinction between cognitive processes and representations, we identify and isolate the main dissociation paradigms; we then critically analyze their key tenets (...) and reported findings.

This paper defends the view that a correct analysis of knowledge must take empirical data into consideration. The data here provided is from experimental psychology, namely from phenomena involving unconscious cognition.

The contemporary metaethical theory, norm-expressivism, maintains that a moral judgment expresses one’s acceptance of norms governing guilt and anger. The theory’s founder, Allan Gibbard, argues that this understanding of the moral claim is supported through both the realization of weaknesses in other accounts and a naturalistic consideration of the way in which moral judgments function in our moral lives. Thus, a moral judgment is the acceptance of norms that permit anger at those who engage in wrongdoing and feelings of guilt (...) by those who do wrong. Because Gibbard arrives at this analysis, in part, through an understanding of the natural psychic mechanisms that determine our moral lives, norm-expressivism is then grounded upon the cogency of certain empirical claims. Should norm-expressivism be a cogent theory, then this would have implications upon the nature of guilt and anger. Guilt and anger would need to, in fact, be stronger motivators than are other moral emotions, moral judgments must be capable of influencing these moral emotions and yet anger and guilt could not entail moral judgments. Should guilt and anger turn out to be moral judgments, then norm-expressivism would offer a circular account of the moral judgment. This project will survey diverse theories of emotion in order to assess the compatibility of these theories with norm-expressivism. After introducing norm-expressivism, I will propose seven conditions for a compatible theory of emotion. I will argue that norm-expressivists can find theories of emotion that frame the nature of guilt and anger in ways consistent with the truth of their metaethical theory. While many facts about the nature of guilt and anger remain unanswered by the scope of this project, I will argue that there are theories of emotion that provide frameworks to explain both the nature of emotion and emotion typology in a way consistent with norm-expressivism.

This article compares research in neuroscience regarding the right and left hemispheres of the brain, particularly in the work of Iain McGilchrist and Robert Ornstein, with Whitehead’s perception in the mode of causal efficacy and in the mode of presentational immediacy, respectively.

Neuroscientific studies have shown that brain activity correlated with a decision to move can be observed before a person reports being consciously aware of having made that decision . Given that a later event cannot cause an earlier one , such results have been interpreted as evidence that decisions are made unconsciously . We argue that this interpretation depends upon an all-or-none view of consciousness, and we offer an alternative interpretation of the early decision-related brain activity based on models in (...) which conscious awareness of the decision to move develops gradually up to the level of a reporting criterion. Under this interpretation, the early brain activity reflects sub-criterion levels of awareness rather than complete absence of awareness and thus does not suggest that decisions are made unconsciously.
