We conduct a game-theoretic laboratory experiment to investigate the nature of information transmission in a communication environment featuring competition and information asymmetry. Two senders have private information about their preferences and simultaneously send messages to a receiver in a one-dimensional space with a large number of states, actions, and messages. We find that equilibrium...

Several studies have shown that a majority of students have problems in learning the topic of integers of the Form One Mathematics. This study was carried out to develop and testing a multimedia learning application with the principles of animation exaggeration on students’ achievement. The experimental study was based on the pre-test postest control group design involving two experimental grou...

Females often choose their mates, instead of mating at random, even when a father contributes nothing but genes to his offspring. Costly female preferences for males with exaggerated traits that reduce viability, such as the peacock's tail, are particularly puzzling. Such preferences can evolve if directly favoured by natural selection or when the exaggerated trait, although maladaptive per se,...

We investigate the role of prosody in child-directed speech of three English speaking adults using data collected for the Human Speechome Project, an ecologically valid, longitudinal corpus collected from the home of a family with a young child. We looked at differences in prosody between child-directed and adult-directed speech. We also looked at the change in prosody of child-directed speech ...

Models of sexual selection suggest that mate-choice preferences are favored because differences between males in their degree of ornamental exaggeration convey useful information about the direct or indirect benefits they have to offer [1-5]. Such arguments assume that variation in male ornament size can be attributed to variation in the degree of sexually selected exaggeration. We provide the ...

Previous studies have focused on the ability of cognitive symptom validity tests to identify simulated malingering or distinguish between clinical samples of individuals at low or high risk of cognitive symptom exaggeration. However, no published studies have examined the latent structure of negative response bias on cognitive tests: measures of cognitive symptom exaggeration may evaluate a con...

Trait exaggeration through sexual selection will tale place alongside other changes in phenotype. Exaggerated morphology might be compensated by parallel changes in traits that support, enhance or facilitate exaggeration: 'secondary sexual trait compensation' (SSTC). Alternatively, exaggeration might be realized at the expense of other traits through morphological trade-offs. For the most part,...

A common variant of caricature relies on exaggerating characteristics of a shape that differs from a reference template, usually the distinctive traits of a human portrait. This work introduces a caricature tool that interactively emphasizes the differences between two three-dimensional meshes. They are represented in the manifold harmonic basis of the shape to be caricatured, providing intrins...

This paper studies a class of decision-making problems under incomplete information which we call “aggregation games.” It departs from the mainstream information aggregation literature in two respects: information is aggregated by averaging rather than majority rule, and each player selects from a continuum of reports rather than making a binary choice. Each member of a group receives a private...
