Perceptual filling-in for vision is the insertion of visual properties (e.g., color, contour, luminance, or motion) into one’s visual field, when those properties have no corresponding retinal input. This paper introduces and provides preliminary empirical support for filled/non-filled pairs, pairs of images that appear identical, yet differ by amount of filling-in. It is argued that such image pairs are important to the experimental testing of theories of consciousness. We review recent experimental research and conclude that filling-in involves brain activity with relatively high integrated information (Φ) compared to veridical visual perceptions. We then present filled/non-filled pairs as …

Across species, unpredictable patterns of maternal behavior are emerging as novel predictors of aberrant cognitive and emotional outcomes later in life. In animal models, exposure to unpredictable patterns of maternal behavior alters brain circuit maturation and cognitive and emotional outcomes. However, whether exposure to such signals in humans alters the development of brain pathways is unknown. In mother–child dyads, we tested the hypothesis that exposure to more unpredictable maternal signals in infancy is associated with aberrant maturation of corticolimbic pathways. We focused on the uncinate fasciculus, the primary fiber bundle connecting the amygdala to the orbitofrontal cortex and a key …

Attention abilities rest on the coordinated interplay of multiple components. One consequence to this multifaceted account is that selection processes likely intersect with perception at various junctures. Drawing from this overarching view, the current research examines how different forms of visuospatial attention influence various aspects of conscious perception, including signal detection, signal discrimination, visual awareness, and metacognition. In this effort, we combined a double spatial cueing approach, where stimulus- and goal-driven orienting were concurrently engaged via separate cues, with Type I and Type II signal detection theoretic frameworks through five experiments. Consistent with the modular view of visuospatial attention, our …
