1 第七章 注意 ◼ 构造主义心理学：冯特（1908）《情感 和注意心理学》； ◼ 机能主义：W. James (1892)《心理学教科 书》； ◼ 行为主义； ◼ 格式塔心理学； ◼ 认知心理学；

Two types of attentionFocused attentionDividedattention

2 Two types of attention ◼ Focused attention ◼ Divided attention

Focused attentionFocus on (select) what's relevant and ignorewhat'sirrelevant.Present two or more inputs and see how wellpeople can concentrate on one and ignore theother. Stroop effects: name the color a word is printedin while ignoring the word itself

3 Focused attention ◼ Focus on (select) what’s relevant and ignore what’s irrelevant. ◼ Present two or more inputs and see how well people can concentrate on one and ignore the other. ◼ Stroop effects: name the color a word is printed in while ignoring the word itself

Divided attention Present two or more inputs and see how wellpeople can concentrate on more than one.Studies of divided attention often used indesigning aircraft --how well can people useinformation from several dials and indicatorsat once. Results from studies such as this areused to design displays that maximizepeople's ability to pay attention to multiplesources of information

Results from studies such as this are used to design displays that maximize people’s ability to pay attention to multiple sources of information

一、注意研究中的主要变量Dependent Variables:Reaction time is by farthe preferred variable and is extensivelyused.Percentage of correct responses is also used,especially in studies of attention in whichmemory plays a role. When an experiment isframed within the context of a particularmodel, such as the theory of signal detection,derived statistics such as d and B are alsousedasdependentvariables

5 一、注意研究中的主要变量 ◼ Dependent Variables: Reaction time is by far the preferred variable and is extensively used. Percentage of correct responses is also used, especially in studies of attention in which memory plays a role. When an experiment is framed within the context of a particular model, such as the theory of signal detection, derived statistics such as d ´ and ßare also used as dependent variables

一、注意研究中的主要变量Independent Variables:These variables centeraround the need for the human to makedecisions and the rate at which such decisionscan be made.varying the number of alternatives;varying the presentation rate of a series ofstimuli;

二、过滤器模型及其双耳同时分听实验的依据对注意的研究是从有关信息缩减问题开始的。人类的各种感官每时每刻都在同时受到许许多多的内外刺激的撞击，由于人类信息加工系统的能力是有限的，人不可能对所有撞击感官的刺激都进行完善加工，所以，人们总是选择重要的而忽略其他的。因此，注意的核心问题也就是对信息的选择分析

8 二、过滤器模型及其双耳同时分听实验的依据 ◼ 对注意的研究是从有关信息缩减问题开 始的。人类的各种感官每时每刻都在同 时受到许许多多的内外刺激的撞击，由 于人类信息加工系统的能力是有限的， 人不可能对所有撞击感官的刺激都进行 完善加工，所以，人们总是选择重要的 而忽略其他的。 ◼ 因此，注意的核心问题也就是对信息的 选择分析

(1)单通道的过滤器模型过滤器模型（filtermodel）是英国心理学家Broadbent（1958）在双耳同时分听实验的基础上提出的一个较早的注意模型输入通道选择性过燃器→反应容量有限的通道刺激长时记忆Broadbent的过滤器模型图7-1

9 （一）单通道的过滤器模型 ◼ 过滤器模型（filter model）是英国心理学家 Broadbent（1958）在双耳同时分听实验的基础 上提出的一个较早的注意模型

(一)单通道的过滤器模型Broadbent认为，来自外界的信息是大量的，而人的神经系统高级中枢的加工能力则是有限的于是就出现了瓶颈。为了避免系统超载，就需要某种过滤器来对之加以调节，选择其中较少的信息，使其进入高级分析阶段，这类信息将受到进一步加工而被识别和存储，而其他信息则不让通过。这种过滤器体现着注意的选择功能。因此这种理论被称为“注意的过滤器模型”。因为这种过滤器模型的核心思想是它到达高级分析水平的通道只有一条，因而Welford（1959）称之为“单通道模型”10
