The current explanations for these variable results include the two-systems proposal -a theoretical framework that suggests that there are multiple systems at play and that these systems do not communicate early in infancy,

These factors and their role in adolescent risk-taking tend to be examined in isolation of other factors, which poses problems for gaining a clear understanding of adolescent risk-taking. The present essay reviews a number of these factors – specifically, social-contextual influences, cognitive and affective decision-making tendencies, impulsivity, sensation seeking, and sex differences – and organizes them within an opportunity-propensity framework. The implications of this approach for risk-taking interventions are briefly discussed

Sturz, Edwards, and Boyer (2014) developed a delayed match-to-sample task that presented a sample of a shape, shape word, or bi-dimensional stimulus (shape and shape word). Post delay, participants identified the sample shape or the sample word by selecting between two shapes or two shape words. An asymmetrical pattern of interference emerged with increased reaction times and errors occurring in matching shape targets but not word targets. This was interpreted as shape words activating a semantic and spatial representation of shapes, but shapes only activating a spatial representation; however, such a pattern of results could have resulted from the shape word being more salient than the shape. The present experiments replicated and extended these results by manipulating figure-ground relations to contrast the original condition with an alternative to address an explanation based upon sample shape saliency (Experiment 1) and by confirming the effectiveness of the saliency manipulation (Experiment 2). Experiment 1 replicated the asymmetrical pattern of results for both conditions, and Experiment 2 confirmed the saliency manipulation. Collectively, these results undermine a pure saliency explanation and have comparative implications for the isolation of geometric processing
