The effects of enhancing cage complexity on the behaviour and welfare of laboratory rats.

abstract：:Continua abound in the natural world, but the treatment of these continua in the psychological study of behavior is often categorical. Four practices and their consequences are considered: limited sampling of a continuum, turning continuous predictors into categories through dichotomization and similar practices, trea...
