To approach the question of motivation toward contraception, the new French law on contraception passed in 1967, and the mode of action and risks of pills, IUDs, and diaphragms are reviewed. The new law governs import sale, prescription, placement of IUDs, consent for minors, and facilities of the clinics that issue contraceptives. Physicians dislike the prescription registration system, the written consent, lack of reimbursement by social security, and neglect of abortion. Oral contraceptives act on gonadotropin release, cervical mucus, and endometrial development. The can cause nausea, weight gain, bleeding, and thromboembolism. The relationship of medicine phobia, forgetting pills, and religion to success with pills remains to be studied. IUDs act on tubal and uterine motility and the endometrium. They frequently cause bleeding, pain, and expulsion, and rarely infection or perforation. Their failure rate is .5-2%. They are indicated when contraception must be separated from sexuality. Diaphragms and caps require technical fastidiousness and usually are preferred by older women. Their failure rate is 10-12% Now that contraceptive research can be done openly in France, more information about contraceptive motivation will become available.

This review identifies four receiver psychology perspectives that are likely to be important in the design and evolution of warning signals. Three of these perspectives (phobia, learning and prey recognition) have been studied in detail, and I include a brief review of recent work. The fourth, a memory perspective, has received little attention and is developed here. A memory perspective asks, 'how might warning signals function to reduce forgetting of avoidances between encounters?'. To answer this question I review data from psychology literature that describe important features of animal long-term memory. These data suggest that components of warning signals may function to reduce forgetting (and therefore increase memorability) by (1) preventing forgetting of learnt prey discriminations; (2) jogging the memories of forgetful predators; and (3) biasing forgetting in favour of prey avoidance when the warning signal of a defended aposematic species is copied by an edible Batesian mimic. A combination of a learning and a memory perspective suggests that the features of aposematic prey that accelerate avoidance learning may also be the features that decelerate forgetting processes. If correct, this would have important implications for the comprehension of signal design. Finally, I suggest that the cryptic appearance of an edible prey may decelerate predator learning and accelerate predator forgetting, to the benefit of the prey. In terms of learning and memory, crypsis may be an antisignal. Copyright 2000 The Association for the Study of Animal Behaviour.
