چکیده
In the card game of poker, players attempt to disguise cues to the quality of their hand, either by concealment (e.g., adopting the well-known, expressionless “poker face”) or by deception. Recent work, however, demonstrates that motor actions can sometimes betray intentions. The same action can have different movement dynamics depending on the underlying intention (Becchio, Sartori, & Castiello, 2010), and these subtle differences can be decoded by observers (Becchio, Manera, Sartori, Cavallo, & Castiello, 2012; Sartori, Becchio, & Castiello, 2011). Thus, professional poker players’ intentions may be visible from their actions while moving poker chips to place bets. Even though professional players may be able to regulate their facial expressions, their motor actions could betray the quality of their poker hand. In three studies, we tested this hypothesis by examining observers’ perceptions of poker-hand quality. We also examined individual differences in sensitivity to nonverbal behavior and potential diagnostic motor behaviors as cues to hand quality.

متن کاملZero-error Slepian-Wolf Coding of Confined Correlated Sources with Deviation Symmetry
In this paper, we use linear codes to study zero-error Slepian-Wolf coding of a set of sources with deviation symmetry, where the sources are generalization of the Hamming sources over an arbitrary field. We extend our previous codes, Generalized Hamming Codes for Multiple Sources, to Matrix Partition Codes and use the latter to efficiently compress the target sources. We further show that ever...
متن کاملThe Redundancy of Slepian-Wolf Coding Revisited
[Draft] In this paper, the redundancy of Slepian Wolf coding is revisited. Applying the random binning and converse technique in [6], the same results in [5] are obtained with much simpler proofs. Moreover, our results reflect more details about the high-order terms of the coding rate. The redundancy is investigated for both fixed-rate and variable-rate cases. The normal approximation (or dispe...
