Comparing solid-body with point-light animations

The movement of faces provides useful information for a variety of tasks and is now an active area of research. We compare here two ways of presenting face motion in experiments: as solid-body animations and as point-light displays. In the first experiment solid-body and point-light animations, based on the same motion-captured marker data, produced similar levels of performance on a sex-judgment task. The trend was for an advantage for the point-light displays, probably in part because of residual spatial cues available in such stimuli. In the second experiment we compared spatially normalised point-light displays of marker data with solid-body animations and pseudorandom point-light animations. Performance with solid-body animations and normalised point-light displays was similar and above chance, while performance with the pseudorandom point-light stimuli was not above chance. We conclude that both relatively few well-placed points and solid-body animations provide useful information about facial motion, but that a greater number of randomly placed points does not support above-chance performance. Solid-body animations have the methodological advantages of reducing the importance of marker placement and are more effective in isolating motion information, even if they are subsequently rendered as point-light displays.

Introspective awareness of sensations

My goal is to formulate a theory of introspection that can be integrated with a strongly reductionist account of sensations that I have defended elsewhere. In pursuit of this goal, I offer a skeletal explanation of themetaphysical nature of introspection and I attempt to resolve several of the main questions about theepistemological status of introspective beliefs.I owe a large debt to Sydney Shoemaker. I have been helped considerably both by conversations with him and by the lectures he gave in the summer of 1985 in his N.E.H. Summer Seminar on Self-Consciousness and Self-Reference. I have also received valuable advice from Richard Lee, David Roach, David A. Schroeder, Lynne Spellman, and (especially) Anthony L. Brueckner, Willem de Vries, and David H. Westendorf.     

Are Newsjunkies More Likely to Vote? Intrinsic Need for Orientation and Voter Registration,Intention to Vote,and Voter Conscientiousness

This study examined the newsjunkie characteristic—intrinsic need for orientation (INFO)—as a predictor of being registered to vote, intention to vote, and voter conscientiousness among a large sample of U.S. adults (N = 2,059), while controlling for media use, news consumption, political partisanship, and demographics. INFO assesses the extent to which people access news in their downtime, feel discomfort when they cannot get news, check news among the first things they do daily, and believe that following news connects them with others. The current study is the first to examine relationships between the sustained, psychological INFO trait and political participation. INFO rests upon theoretical frameworks of uses and gratifications and self-determination theory, both of which are employed in this study. INFO was positively correlated with being registered to vote, with intending to vote in the 2020 U.S. election, and with voter conscientiousness, even after controlling for numerous other variables. Additionally, INFO was still positively associated with the political participation variables after political news consumption was included as a mediator in three mediation analyses.
