Effects of experimentally manipulating camera cuts (high vs. low frequency) and music (present vs. absent) on total and selective visual attention to and imitation of prosocial TV programs were examined. Subjects were 96 adults (mean IQ = 46). Within programs, selective viewing of content features (dialogue, distress, helping, and reinforcement) and media features (music, cuts, zooms, and scene changes) were examined. Subjects selectively attended to cuts and zooms and all four content features. High-cuts frequencies in a program reduced selective attention and subsequent verbal imitation. There were no significant effects for music.
研究了通过实验操纵镜头切换（高频与低频）和音乐（有与无）对亲社会电视节目的总体视觉注意力、选择性视觉注意力以及模仿行为的影响。研究对象为96名成年人（平均智商 = 46）。在节目中，对内容特征（对话、困境、帮助行为和强化）和媒体特征（音乐、镜头切换、变焦和场景变化）的选择性观看进行了研究。研究对象选择性地关注镜头切换、变焦以及所有四种内容特征。节目中的高频镜头切换频率降低了选择性注意力和随后的言语模仿。音乐没有显著影响。
