Several studies in the past have demonstrated a strong correlation of finger lengths ratio and human personality. This current prospective study attempts to correlate the finger length ratio of the 4 to 5 finger in males and females with the human personality traits --Psychoticism, Neuroticism & Extraversion using EPQ (Eysenck Personality Questionnaire). The hypothesis in this study is that mal...

We provide an analysis of hold out and giving (Ho&G) behaviours in pre-linguistic infants, and investigate their relationship with index finger pointing. The frequency of Ho&Gs at 10 and 11 months along with the length of the following social interaction correlated with index finger pointing at 12 months. We conclude that Ho&Gs are a precursor to index finger pointing and that this provides sup...

PURPOSE Metacarpal fractures are common in hand surgery. Metacarpal shortening ranging from 2 mm to as much as 10 mm has been deemed acceptable in the literature. We examined the effect of metacarpal shortening on interosseous muscle architecture and predicted force production capacity based on the standard muscle length-tension curve (commonly known as the Blix curve). METHODS The dorsal int...

QTUDENTS of psychology are familiar with the experiments of ~ Weber on the sense of touch. He found that different parts of the surface differ widely in their ability to give information concerning the things touched. Some parts, which yielded vivid sensations, yielded little or no knowledge of the size or form of the thing exciting it; whereas other parts, from which there came sensations much...

Postmortem measurements were made of distances from skin surface to underlying bone/cartilage on 43 children (up to 8 y old; weights from 0.7 to 26.4 kg) to determine optimal sites and lengths of lancet tips for skin puncture of the heel, great toe, and middle finger. For measuring depths, a needle-like probe was devised that minimized disfigurement. As long as the infant's heel was available f...
