The broaden-and-build theory (Fredrickson, 1998, 2001) hypothesises that positive emotions broaden the scope of attention and thought-action repertoires. Two experiments with 104 college students tested these hypotheses. In each, participants viewed a film that elicited (a) amusement, (b) contentment, (c) neutrality, (d) anger, or (e) anxiety. Scope of attention was assessed using a global-local visual processing task (Experiment 1) and thought-action repertoires were assessed using a Twenty Statements Test (Experiment 2). Compared to a neutral state, positive emotions broadened the scope of attention in Experiment 1 and thought-action repertoires in Experiment 2. In Experiment 2, negative emotions, relative to a neutral state, narrowed thought-action repertoires. Implications for promoting emotional well-being and physical health are discussed.
拓展与建构理论(弗雷德里克森,1998年,2001年)假设,积极情绪会拓宽注意力范围和思维行动指令库。两项针对104名大学生的实验对这些假设进行了测试。在每项实验中,参与者观看一部引发(a)愉悦、(b)满足、(c)中立、(d)愤怒或(e)焦虑的影片。注意力范围通过一项全局-局部视觉加工任务进行评估(实验1),思维行动指令库通过一项20个陈述测试进行评估(实验2)。与中立状态相比,积极情绪在实验1中拓宽了注意力范围,在实验2中拓宽了思维行动指令库。在实验2中,与中立状态相比,消极情绪缩小了思维行动指令库。文中还讨论了该理论对促进情绪健康和身体健康的意义。
