Perceivers generally show a poor ability to detect changes, a condition referred to as “Change Blindness” . They are, in addition, “blind to their own blindness”. A common explanation of this “Change Blindness Blindness” is that it derives from an inadequate, “photographical” folk-theory about perception. This explanation, however, does not account for intra-individual variations of CBB across trials. Our study aims to explore an alternative theory, according to which participants base their self-evaluations on two activity-dependent cues, namely search time and (...) perceived success in prior trials. These cues were found to influence self-evaluation in two orthogonal ways: success-feedback influenced self-evaluation in a global, contextual way, presumably by recalibrating the norm of adequacy for the task. Search time influenced it in a local way, predicting the success of a given trial from its duration. (shrink)

We investigate the nature of the sense of presence that usually accompanies perceptual experience. We show that the notion of a sense of presence can be interpreted in two ways, corresponding to the sense that we are acquainted with an object, and the sense that the object is real. In this essay, we focus on the sense of reality. Drawing on several case studies such as derealization disorder, Parkinson’s disease and virtual reality, we argue that the sense of reality is (...) two-way independent from the spatial and sensory contents of experience. We suggest that the sense of reality is an affective experience akin to a metacognitive feeling. Finally, we present a potentially important implication of our account for the current debate between Intentionalism and Naïve Realism. Since perception is “opaque” with respect to the reality of what is perceived, Intentionalism cannot refer to the sense of reality as what differentiates perception from sensory-like experiences such as imaginings. In contrast, Naïve Realism has an independent explanation of the specificity of perception. (shrink)

Over the last few decades, empirical researchers have become increasingly interested in explaining the formation of “basic” aesthetic judgments, i.e. simple judgments of sensory preferability and the pleasure that seems to accompany them. To that end, Reber et al. have recently defended a “processing-fluency” view, which identifies aesthetic pleasure with one’s ability to easily process an object’s perceptual properties (e.g. Reber 2012 ). While the processing-fluency theory is certainly an improvement over its competitors, it is currently vulnerable to several serious (...) criticisms. In what follows, I aim to provide a more holistic, explanatorily robust, model of the processing-fluency theory of aesthetic pleasure by incorporating what the view neglects: the crucial role of perceptual disfluency, interest, and the underlying values that drive aesthetic appraisal.
