In this study the occurrence of an “other-age” effect on age estimation was assessed. This effect consists in a more accurate estimation of own-age faces than other-age faces. Here, the age of participants (10 to 14 year old children and 20 to 30 year old adults) and the age of stimuli (faces of 10 to 14 year old children and faces of 20 to 30 year old adults) were crossed. Although we did not observe a crossed interaction where each age group would have been more accurate for in-group estimation than for out-group estimation, present results revealed the occurrence of an own-age bias in age estimation. Although both groups did not differ when estimating child faces, adults were more accurate than children when estimating the age of adult faces. Therefore, the present results showed an asymmetrical "other-age" effect. Several hypotheses explaining the present pattern of results are discussed. [less ▲]

Previous studies have shown that, in person-recognition tasks, people performance better for gaces belonging to their own race than for those belonging to another race. Recently, however, this 'other-race' effect has also been found in a sex-discrimination task (O'Toole et al, 1996, Perception 25, 669-676). In the present study, we investigated wheter this finding extends to age perception. Caucasian and African participants were asked to estimate the age of Caucasian and African faces. The main result of this experiment was a significant 'race of subject' x 'race of face' interaction showing that Caucasian participants performed better at evaluating Caucasian faces than African faces. However, African participants performed equally with both type of faces. This result is explained by the Africans' time of residence in Belgium. This implication of this 'older-race' effect for age estimation is discussed with respect to eyewitness reports. [less ▲]

The biomineralization of otoliths results mainly from the release of soluble Ca(2+), which is in turn precipitated as CaCO(3) crystals. In some Carapidae, sagittae sections have been shown to reveal a three-dimensional asymmetry with a nucleus close to the sulcal side, an unusual position. This study seeks to understand otolith formation in Carapus boraborensis. The unusual shape of the otolith is partly explained by the distribution of the epithelium cells, and particularly the sensory epithelium. Experimental evidence shows for the first time that aragonite growth takes place along the c-axis. These aragonite needles present two different habits. On the sulcal side is found the acicular form resulting from rapid growth during a short period of time. On the anti-sulcal side, the prismatic form seen there is due to a slower growth speed over longer periods. The otolith surface was observed each hour during a period of 24h in fishes reared in similar conditions. This allowed for the first time the direct observation on the otolith surface of the deposition of the two layers (L-zone and D-zone). In C. boraborensis, the organic-rich layer (D-zone) develops during the day, whereas the CaCO(3) layer (L-zone) seems to be deposited during the night. [less ▲]

The development of experimental animal models has played an invaluable role in understanding the mechanisms of neurosensory deafness and in devising effective treatments. The purpose of this study was to develop an adult mouse model of ototoxic drug-induced hearing loss and to compare the ototoxicity in the adult mouse to that in the well-described guinea pig model. Mice are a powerful model organism, especially due to the large availability of antibodies, probes and genetic mutants. In this study, mice (n=114) and guinea pigs (n=35) underwent systemic treatment with either kanamycin or cisplatin. Auditory brainstem responses showed a significant threshold shift in guinea pigs 2 weeks after the beginning of the ototoxic treatment, while there was no significant hearing impairment recorded in mice. Hair cells and neuronal loss were correlated with hearing function in both guinea pigs and mice. These results indicate that the mouse is not a good model for ototoxicity, which should be taken into consideration in all further investigations concerning ototoxicity-induced hearing loss.
