Emotionality in male and female rodents: a reply to Archer.

Archer (1979) has complained that his criticisms (Archer, 1971, 1973, 1975) of Gray's (1971 a, b) views on emotionality and on sex differences in fearfulness in rodents have not been answered. These criticisms are shown to lack substance and to depend on confused arguments and misleading reviews of the literature.
