A remarkable result, due to Moore & Repullo (1988) is that any social choice function can be implemented as the unique equilibrium of a suitably constructed dynamic game (subgame perfect implementation). Yet such mechanisms are never observed in practice, which raises the question: why not? In this paper we test such mechanisms experimentally and find that even small deviations from perfect inf...

The present study investigates the effects of neighborhood size and neighborhood frequency in reading Chinese two-character words. The neighborhood size of a word is defined as the summation of neighbors sharing the first constituent (neighborhood size 1) and the second constituent (neighborhood size 2) characters. The first experiment found two opposite neighborhood size effects in lexical dec...

The authors investigated semantic neighborhood density effects on visual word processing to examine the dynamics of activation and competition among semantic representations. Experiment 1 validated feature-based semantic representations as a basis for computing semantic neighborhood density and suggested that near and distant neighbors have opposite effects on word processing. Experiment 2 conf...

Two experiments employing an auditory priming paradigm were conducted to test predictions of the Neighborhood Activation Model of spoken word recognition (Luce & Pisoni, 1989, Neighborhoods of words in the mental lexicon. Manuscript under review). Acoustic-phonetic similarity, neighborhood densities, and frequencies of prime and target words were manipulated. In Experiment 1, priming with low f...

Two lexical decision experiments, using words that were selected and closely matched on several criteria associated with lexical access provide evidence of facilitatory effects of orthographic neighborhood size and no significant evidence of inhibitory effects of orthographic neighborhood frequency on lexical access. The words used in Experiment 1 had few neighbors that were higher in frequency...

Efficient communication is essential in disasters in order to coordinate a response and assure effective evacuation. This paper focuses on the case study of the Melbourne bushfires in 2009. We first analysed some interviews of the population to know who the population communicates with (neighbours, family, authorities, etc), and using what channel (radio, phone, internet, etc). We then develope...
