Toys listed in the Cause Effect Category are selected because they best facilitate the teaching of basic cause-effect. Cause-Effect is an early language concept where and individuals learns that if they do something, there will be a direct result. Such as, if I press a button, a toy will play. When I stop pressing the button, the toy will stop. Toys that continue to play after a switch is released are not suited for teaching this concept, but are engaging and fun once an individual understands Cause-Effect concept. Cause-Effect is a precursor to language development. Cause-Effect language is important because it allows a person to effectively communicate causative relationships between events.
