The importance of an ecologically valid method in the evaluation of toddler interaction with coloured liquid laundry detergent capsules.

ABSTRACT: The colour and appearance of liquid laundry capsules have been implicated in the risk of attracting the attention of toddlers, and therefore contributing to poisoning incidents in the home by encouraging interaction. This research set out to explore if differences in colours and contrasting colour designs used in mono and multi-coloured capsules result in different levels of attractiveness. This was performed using two study settings: a laboratory setting (out of context), and by comparison, a more ecologically valid setting, mimicking the real-world. Capsule attractiveness to toddlers was measured by visual attention (measured through eye tracking) and grasping choice (measured as frequency of grasping in a behavioural task). Results from the research in the out of context setting showed statistically significant differences in visual attention and grasping choice between colours and contrasting designs. In the visual attention study a preference for multi-coloured capsules was shown. In the grasping choice study, in addition to multi-coloured, mono-coloured white or purple capsules were also preferred. In the more ecologically valid setting, there were no statistically significant differences in the visual attention or grasping choice between any of the capsules. These results were consistent with each other and in line with market data reflecting poisoning incident rates, which show no change with colour or contrasting colour design. We suggest that the results from out of context studies might not be a reliable indicator of real world behaviour. Given the importance of toddler home safety, using a methodology that is aligned with market numbers is crucial to develop countermeasures.

Project description:Liquid laundry capsules have been involved in multiple poisoning incidents with young children in the home. There are a range of contributing factors for these incidents, including influences from industry, culture, home environments, and parenting/supervision. There also are influences from children's behaviour and decisions in reaction to potential hazards. Previous research examined the influence of capsule product appearance and colour on children's behaviour around hazardous household items, but little research examines the influence of product size. This research explored if differences in the size of liquid laundry capsules result in different levels of toddler interaction. We compared two commercially available capsule designs that are identical in physical appearance but differ in physical size. Our research was conducted using three studies: Study 1, forced-choice test in an out-of-context laboratory setting; Study 2, an ecologically-valid, simulated real-world setting replicating a home laundry cabinet with a container of capsules left open; and Study 3, a second ecologically-valid study replicating a home laundry cabinet, this time with a capsule left outside its container. Capsule interaction was measured by grasping choice among samples of 156 toddlers ages 9-36 months. The same sample was used for Studies 1 and 2, and a second identically sized sample recruited for Study 3. Results from Study 1 indicated toddlers selected the small (49.8% selection) and large (50.2%) capsule with nearly identical frequency. Study 2 largely replicated Study 1: Toddlers selected the small capsule or container of small capsules 26.8% of the time and the large capsule or container of large capsules 22.3% of the time. Study 3 also replicated previous findings: Toddlers selected the smaller capsule 18.0% of the time and the larger 19.2%. We discuss study results, which suggest no appreciable difference in toddler's grasping choice to smaller versus larger laundry capsules.
