Parent and child co-resident status among an Australian community-based sample of methamphetamine smokers.

Introduction: Children in families where there is substance misuse are at high risk of being removed from their parents' care. This study describes the characteristics of a community sample of parents who primarily smoke methamphetamine and their child or children's residential status.

Design And Methods: Baseline data from a prospective study of methamphetamine smokers ('VMAX').

Container size exerts a stronger influence than liquid volume on the perceived weight of objects.

Many features of an object can influence how we predict and perceive its weight. The current study evaluated the relative contributions of sensory and conceptual processing of object features on weight perception. We employed a novel paradigm to investigate how container size and the amount of liquid inside can influence the perceived weight of bottles and the forces deployed when lifting them.
