title: Studies on tube restraint-induced attack on a metal target by laboratory mice.
abstract: This study examines factors influencing the attack on a metal target by laboratory 'TO' strain mice confined within a narrow perspex tube and contrasts this form of behaviour with attack seen in less equivocal forms of 'aggression test'. The effects of sex, housing condition, reproductive experience, density, anosmia and castration (in the male) were systematically examined. This 'model' of 'aggression' shows few parallels with social conflict, parental defense and electroshock-induced forms of attack as none of the above manipulations influenced the level of target biting in this situation. Thus, in spite of claims that tube restraint-induced attack may show parallels with intermale aggression, the data suggest that it involves a totally different motivation.
