Previous research has found a disparity between the language trajectories of children within a high, medium, or low-economic-status family. A relationship is reliably found between the language trajectory of toddlers and success throughout school. This study will evaluate a training package to teach parents to engage in behaviors that promote language and assess the training's short-term effect on the trajectories of children (i.e., growing language) within low-socioeconomic backgrounds. Specifically, experimenters will evaluate the impact of the dosage of video modeling, self-evaluation, and self-monitoring on the acquisition of the targeted skills. Data may suggest that the more accurate the individual is with self-evaluating their own behavior, the more robust behavior change will be seen. The results from this training will inform the barriers and next steps to creating a low-cost training resource for organizations serving families with a low-socioeconomic status income bracket.
