Abstract How can deceptive communication signals exist in an evolutionarily stable signalling system? To resolve this age-old honest paradox, researchers must first establish whether deception benefits deceivers. However, while vocal exaggeration is widespread the animal kingdom and assumably adaptive, its effectiveness biasing listeners has not been established. Here, we show that human detect...

Pilgrimage is an important element of religious life in most religions. It no exaggeration to say that the Bible a record long pilgrimage history people Israel. Buddhism also has tradition Holy Land, which contains Buddha

Butterflies are among nature's most colorful animals, and provide a living showcase for how extremely bright, chromatic and iridescent coloration can be generated by complex optical mechanisms. The gross characteristics of male butterfly colour patterns are understood to function for species and/or sex recognition, but it is not known whether female mate choice promotes visual exaggeration of t...

Using Mandarin Chinese, a "tone language" in which the pitch contours of syllables differentiate words, the authors examined the acoustic modifications of infant-directed speech (IDS) at the syllable level to test 2 hypotheses: (a) the overall increase in pitch and intonation contour that occurs in IDS at the phrase level would not distort lexical pitch at the syllable level and (b) IDS provide...

We present a novel method for caricature synthesis based on mean value coordinates (MVC). Our method can be applied to any single frontal face image to learn a specified caricature face pair for frontal and 3D caricature synthesis. This technique only requires one or a small number of exemplar pairs and a natural frontal face image training set, while the system can transfer the style of the ex...

Extreme over-reliance on the impaired forelimb following unilateral lesions of the forelimb representation area of the rat sensorimotor cortex (FL-SMC) leads to exaggeration of injury when overuse is begun during the first week, but not later periods, after injury. Behavioral impairment is partially worsened by the additional tissue loss. In the present study, we show that complete disuse of th...

Symptom validity tests (SVTs) are predicated on the assumption that overendorsement of atypical symptoms flags symptom exaggeration (i.e., questionable symptom validity). However, few studies have explored how practitioners from different cultural backgrounds evaluate such symptoms. We asked professionals working in Western (n = 56) and non-Western countries (n = 37) to rate the plausibility of...
