CMN 147 Exam 2The Case of Baby Einstein - correct answer DVD for babies that didnt teach them squat because of video deficit.

Visual Perception - correct answer due to a lack of working memory, children cant take a 2D image and transfer the knowledge into a 3D world. Auditory Perception - correct answer due to lower levels of working memory, children need 3d visual cues to go along with auditory stimuli Symbolic Representations - correct answer At young ages, children struggle to understand that one thing can stand for something else Learning through a screen exacerbates this issue Object retrieval - tests symbolic representation (2nd child only 6 months older but did it) Ex: goal was to teach about sand - good b/c more content than Baby Einstein; some repetition Any distract-er (like sounds) will take away from learning What can be done to help?
