CMN 147 Exam 2The Case of Baby Einstein - correct answer DVD for babies that didnt teach them squat because of video deficit. The Video Deficit - correct answer Children < 3 years of age are unable t learn from screens because of the lack of cognitive development. 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? (the video deficit) - correct answer Making the presentation more real or meaningful If children think that the representation is really the actual thing, then they show a willingness to learn For example, in one study, the researchers told the children that the room was shrunk by a "shrinking machine". They then un-shrunk the room to its normal size, and children were able to locate the hidden toy Researchers also videotaped the children and had them watch themselves on television Afterwards, they were much better at the object retrieval task than children without that experience watching themselves
