不同年龄广告名人效应的心理加工机制研究   总被引:4,自引:1,他引:3  
陈宁 《心理科学》2003,26(1):37-40
本研究从自动化加工和控制性加工这个视角研究了名人效应的心理加工机制。实验运用加工分离程序,探讨了不同年龄阶段的受众对名人广告的信息加工模式。结果发现:(1)名人效应是一个普遍存在的现象,与用一般消费者做代言人相比,青少年、成年人(大学生)以及老年人对名人广告均明显存在更多的自动化加工,且加工水平没有年龄差异。但是,老年人的控制性加工明显低于其他两组;(2)在非注意条件下,代言人的专业化程度明显地影响了大学生组的控制性加工,但与各组被试的自动化加工都关系不大。这些研究发现为广告策略的制定带来了一些新的启示。  相似文献

Abstract: This article argues that Christine Korsgaard's conception of self‐constitution can be historicized by considering the impact of actual humans on our reflective activity. Because Korsgaard bases her argument on a philosophy of action rather than of intention (as Kant does), and our actions must always be concrete, the article argues that the principles for action which we develop in reflection are likewise responses to concrete human demands. It further interprets the types of demands humans make on each other as the expression of historical circumstance rather than as transcendentally anchored. The notion of universal respect that reflection seeks to achieve is thus seen as developing by a self‐correcting process of concrete human interaction. Finally, the article concludes that there can be no metaphysical proof of morality, since morality develops through human interaction that seeks to approximate the idea of respect for persons.  相似文献

We conducted a parametric analysis of response suppression associated with different magnitudes of noncontingent reinforcement (NCR). Participants were 5 adults with severe or profound mental retardation who engaged in a manual response that was reinforced on variable-ratio schedules during baseline. Participants were then exposed to NCR via multielement and reversal designs. The fixed-time schedules were kept constant while the magnitude of the reinforcing stimulus was varied across three levels (low, medium, and high). Results showed that high-magnitude NCR schedules produced large and consistent reductions in response rates, medium-magnitude schedules produced less consistent and smaller reductions, and low-magnitude schedules produced little or no effect on responding. These results suggest that (a) NCR affects responding by altering an establishing operation (i.e., attenuating a deprivation state) rather than through extinction, and (b) magnitude of reinforcement is an important variable in determining the effectiveness of NCR.  相似文献

文章主要介绍了语义启动的过程及其脑机制的研究进展。启动效应是内隐记忆的研究焦点,而语义启动是通过刺激的语义特征来研究启动效应的。语义启动的脑机制研究一般是通过脑损伤、脑成像和ERPs等方法实现的。研究表明,大脑的广泛区域都参与着语义启动过程,尤其是脑前区和大脑的左半球。  相似文献

DETECTION OF THE VELOCITY OF MOVEMENT OF VISUAL STIMULI BY PIGEONS   总被引:3,自引:2,他引:1       下载免费PDF全文
Nine pigeons were trained to discriminate a moving stimulus from a stationary stimulus. In one experiment, the stimulus was a rotating disc with radial stripes. In a second experiment, the stimulus was a vertically moving film strip with horizontal bars. Several psychophysical procedures were used to determine the minimal detectable velocity of movement. The detection thresholds for most of the pigeons fell in the range of 4.4 to 6.5 millimeters per second, corresponding to a retinal velocity of 4.1 to 6.01 degrees per second. A signal detection analysis of the psychophysical data indicated systematic changes in response bias that were related to the ordinal position of the stimulus velocity in the sequence.  相似文献

The effects of five procedures on the acquisition of conservation of length were studied. A Müller-Lyer illusion was used to induce apparent changes in length in the test- and practice-situations. Two procedures involved practice on addition-subtraction, one a progressive increase in the strength of the Müller-Lyer illusion, and one the anticipation of the outcome of displacements of the objects. A fifth procedure was a composite of the other four. The results showed some acquisitions in all groups, with highest frequency in the anticipation group, and lowest in the increase-in-illusion group.  相似文献

FOK产生机制的重新检验   总被引:1,自引:0,他引:1  
以中文低频字对为学习材料,采用被试内设计的方法对FOK产生机制,即靶项目强度、线索熟悉性以及两者之间联系强度对FOK的影响进行了重新检验。实验结果表明:单独的靶项目强度对FOK判断没有影响,而单独的线索熟悉性对FOK判断存在影响,线索与靶项目联结强度对FOK判断存在影响。线索熟悉性和联结强度对FOK的影响可能相互独立。  相似文献

We compared the subtlety of four measures of sexism and sources of variation in male and female psychology students' judgments that beliefs from these scales and everyday behaviors were sexist. Participants judged traditional gender role and hostile sexist beliefs as more sexist than benevolent and modern sexist beliefs, indicating the latter were more subtle measures of sexism. Participants also judged traditional gender role behaviors as more sexist than unwanted sexual attention, suggesting the latter may less readily be identified as sexist. Variation in judgments of beliefs as sexist was related to differences in likelihood of endorsing such beliefs. This relation fully accounted for the tendency for men to be less likely to judge beliefs as sexist in comparison to women. Endorsement of Modern and Hostile Sexist beliefs was related to judgments of behaviors as sexist. The implications of the results for scale usage and identifying sexist behavior are discussed.  相似文献

FOK产生机制的再验证   总被引:3,自引:0,他引:3  
韩凯  沈大为  李波 《心理学报》2001,34(1):13-16
通过用有意义联系和无意义联系的两种中文词对作为识记材料,在以前实验研究基础上,进一步验证关于FOK(Feelingof Knowing)产生机制的两种理论假说,即靶项日记忆强度假说(或靶项目提取可能性假说)与线索熟悉性假说。实验结果表明,靶项目记忆强度和线索熟悉性程度都能决定FOK判断等级的高低,说明两种假说并非绝对对立,非此既彼。但此二因素都需达到一定程度,才能显著影响FOK判断等级的高低。  相似文献

任务难度对基于位置返回抑制时间进程的影响   总被引:10,自引:5,他引:5  
王玉改 《心理科学》1999,22(3):205-208
在返回抑制的实验范式下,采用线索一靶子模式进行了视觉字母觉察实验、实验发现,返回抑制在线索与靶子之间的时间间隔(SOA)为700ms时出现,且在900ms时消退。这与先前许多实验发现的返回抑制在SOA为300ms左右时出现的结果不一致。作者认为,实验任务的难度是影响返回抑制时间进程的一个重要因素。  相似文献

汉字材料的熟悉性和复杂性对视觉短时记忆(VSTM)广度的影响研究存在分析。本研究在实验设计上区分了汉语字词的熟悉性和复杂性维度,探讨了它们对VSTM广义的不同影响程度,结果表明:(1)材料的熟悉性是影响汉语字词VSTM广度的最重要因素,材料的复杂性影响不大;(2)在材料熟悉程度一致,被试在11-20岁年龄范围条件下,汉语字词VSTM广义将保持相对恒定(3)在承认“组块假说”的前提,汉语字词VSTM  相似文献

Two experiments were designed to test information extraction capacity from briefly shown photographs depicting simple familiar objects and facial/affective stimuli. Photographs were presented tachistoscopically at six exposure times, 1 sec, 200 msec, 40 msec, 20 msec, 4 msec, 2 msec, to chronic schizophrenic patients, general medical patients, and nonpatient control subjects. Experiment 1 was conducted using the number of correct responses (true scores) and experiment 2 using the number of trials taken (error scores) to identify the target stimuli, as the dependent measures. In experiment 1, schizophrenics did not differ from general medical patients but both were inferior to nonpatient controls in identifying brief visual stimuli. However, in experiment 2, schizophrenics required significantly more trials than general medical patients, who in turn required significantly more trials than nonpatient controls in identifying brief visual stimuli.  相似文献
