Sexual attraction/avoidance

Physical means of information are found with all living organisms. Chemical signaling is typical ofthe lower organisms and, through the vomeronasal neurons, the animals (Leinders-Zufall 2000). The latter rely also on sound and colors as information systems. Sound is flatly repetitive, such as with birds, to avoid breeding between closely related species. With man (MacNeilage 2000), and perhaps also apes and dolphins (Nowak 2000), soimd is syntactic. Man seems to have also inherited a rudimentary chemical information system, that is, sexual attraction exerted by pheromones released fi om the armpits (Stem 1998). However, the claim remains to be fiilly substantiated. [Pg.107]

Not surprisingly, many studies have considered attraction/avoidance as indicators of detection of sexual advertisement pheromones (Dawley 1984a, 1984b Walls et al. 1989 Malacame Vellano 1987 Cogalniceanu 1994). These responses are the easiest to quantify and interpretation of the results may be more straightforward for sexual advertisement pheromones than for territorial pheromones (see discussion above). For example, males are predicted to be attracted to females and individuals of either sex should be attracted to potential mates that they find more attractive. [Pg.287]

All these data indicate that, at least in laboratory conditions, adult females are consistently attracted by chemical cues excreted in urine by adult males. There is some evidence, however, that male mouse urine is attractive only for sexually mature females. In one study it was shown that adult females were more attracted to male urine than to female urine, while prepubertal females were more attracted to female urine (Coppola O Connell, 1988). This finding is confirmed by other assays, using preference chambers and stick-chewing tests prepubertal females avoided male signals, but at puberty they began to prefer adult male odors. The opposite pattern of responses was elicited by female olfactory signals, that is, female urine is preferred by females during the prepubertal period and are avoided by adults (Drickamer, 1989). [Pg.360]

Gay, lesbian, bisexual or sexually uncertain teens have higher risks of self-harm If their sexuality hasn t yet coalesced into an identity, avoid labels and ask who they re attracted to, e.g. Some teenagers have problems or worries about who they find attractive. Do you worry about that ... [Pg.535]
