Challenging physiognomy: questioning the idea that facial characteristics are indicative of personality

Physiognomy; the idea that facial characteristics are indicative of personality has persisted within the science of psychology despite some questionable supporting evidence. Indeed the idea is not unreasonable if certain premise can be supported. The aim of this research was to test three related premise in order to ascertain whether people could accurately judge the personality of a stranger from only a superficial exposure. An experiment was devised which exposed participants to one of eight video clips. The video clips were all of the same person but varied in duration, whether the eyes were visible, and whether the person was talking. One hundred and forty participants took part in the study. After watching one of the video clips each participant was asked to assess the personality of the person in the video using a standard personality questionnaire. The null results challenge the findings of previous research in support of physiognomy

Performance of a Multiple-Access DCSK-CC System over Nakagami-mm Fading Channels

In this paper, we propose a novel cooperative scheme to enhance the performance of multiple-access (MA) differential-chaos-shift-keying (DCSK) systems. We provide the bit-error-rate (BER) performance and throughput analyses for the new system with a decode-and-forward (DF) protocol over Nakagami-$m$ fading channels. Our simulated results not only show that this system significantly improves the BER performance as compared to the existing DCSK non-cooperative (DCSK-NC) system and the multiple-input multiple-output DCSK (MIMO-DCSK) system, but also verify the theoretical analyses. Furthermore, we show that the throughput of this system approximately equals that of the DCSK-NC system, both of which have prominent improvements over the MIMO-DCSK system. We thus believe that the proposed system can be a good framework for chaos-modulation-based wireless communications.Comment: 4 pages, 5 figures, accepted, IEEE ISCAS, 201
