身体映像影响因素的生态系统分析

身体映像对个体的身心发展有重要的意义, 对它的研究在近20年来更是如火如荼地发展。根据布朗芬布伦纳的生态系统理论, 从微系统(父母、同伴、伴侣)、外系统(媒体)、宏系统(社会文化)以及处于系统中的个体因素四个方面, 对影响身体映像的因素进行初步的分类和归纳, 为身体映像的干预措施提供参考。     

数量化维度特征搜索的影响因素探索

有关数量化维度特征搜索的研究表明 ,目标搜索斜率 (反应时间对呈现项目数量函数的斜率 )是由目标与干扰子之间的差异决定的 ,然而以往研究中其差异的值取决于具体的实验条件。根据韦伯定律 ,笔者推测 ,目标搜索斜率应由目标与干扰子之间的相对差异 (C)决定 ,C为目标值 (T)与干扰子值 (D)的差值与该干扰子值的比值。当C值对应相等时 ,不同几何形状刺激的目标搜索斜率应无差异。为此笔者分别采用圆 (实验一 )和三角形 (实验二 )进行实验研究。实验结果支持了上述假设 ,并发现目标大于干扰子时的目标搜索斜率对C值的函数是单调递减函数     

整体-局部范式下的负启动效应

在通常的负启动范式基础上 ,以小数字构成的大数字 ,即以同时具有整体特征和局部特征的复合数字为实验材料 ,采用数字命名任务 ,将刺激画面中复合数字的数目和注意指向作为变量进行实验。大学生充任被试。结果发现 ,在单个复合数字条件下对同一客体的非注意指向的特征进行忽略重复 ,注意整体时出现负启动 ,而注意局部时不出现负启动 ;在两个复合数字条件下对启动刺激中充当干扰项的复合数字进行忽略重复 ,则注意整体与注意局部都出现了负启动。该研究表明 ,在不同注意指向时 ,整体 -局部范式下的负启动效应具有知觉组织的层次性 ,并显示出客体内选择和客体间选择对负启动的不同影响。     

双任务间隔对特征搜索方式的影响

采用RSVP序列,以两个实验探讨了双任务间隔对特征搜索方式的影响。要求试被首先辨认数字序列中包含的字母(任务一,T1),随后完成特征搜索任务(任务二,T2)。在实验一中,T2是检测在同时呈现的多个椭圆中是否有方向不一致的目标出现;在实验二中,T2是检测同时呈现的多个灰色圆点中是否有红色圆点出现。结果发现:随T1-T2间距缩短,T2的正确率显著下降;T2所含刺激数目的增加并未引起其正确率下降,即任务转换只影响特征搜索的绩效而未改变搜索方式,特征搜索仍以并行方式进行。根据动态控制理论,由于在本研究范式中两个任务之间存在任务转换过程,特征搜索应当为系列搜索。可见上述结果与动态控制理论不符。     

表面特征和结构特征在故事类比通达中的作用

在基于相似性的迁移研究中,表面特征和结构特征在类比提取过程中的作用是研究者关注的中心课题。自20世纪90年代以来,不同的研究者在故事类比通达研究的基础上,得出有关表面特征和结构特征的作用的不同结论。文章以表面特征和结构特征的概念为切入点,主要介绍表面特征和结构特征在故事类比通达中的作用的理论分歧与类比通达模型,指出当前的研究中存在的问题,并提出新的类比通达研究的框架。     

Thin-Ideal Internalization: Mounting Evidence for a New Risk Factor for Body-Image Disturbance and Eating Pathology

Body-image disturbance and eating disorders are a significant physical and mental health problem in Western countries. We describe emerging work on one newly identified variable that appears to be a potent risk factor for the development of these problems internalization of societal standards of attractiveness. Work conducted independently in our labs over the past decade has included scale development, correlational studies, prospective risk-factor studies, randomized experiments, and randomized prevention trials. Findings collectively suggest that internalization is a causal risk factor for body-image and eating disturbances, and that it appears to operate in conjunction with other established risk factors for these outcomes, including dieting and negative affect. Future research is needed to examine the specific familial, peer, and media influences that promote internalization and to replicate and extend our prospective and experimental studies.     

Perceived relationship with God moderates the relationship between social comparison and body appreciation

Social comparison has been shown to contribute to the negative attitudes that most Western women have towards their bodies. However, minimal research has addressed the relationship between social comparison and body appreciation, which entails holding favourable opinions towards the body, accepting the body along with its deviations from societal beauty ideals, respecting the body by engaging in healthy behaviours, and protecting the body by rejecting unrealistic media appearance ideals. This study tested whether feeling loved and accepted by God would weaken the inverse relationship between social comparison and body appreciation among a sample of 186 female undergraduates. Results showed that frequent body-related comparisons were related to lower body appreciation, but this relationship was conditional upon the quality of women's perceived relationship with God. Results suggest that future research should explore interventions designed to create improved secure attachment relationships between clients and God.     

智能革命时代下脑机接口之于人类延展的伦理审思

脑机接口通过解码人类思维活动过程中的脑神经活动信息,构建出人脑与外部环境之间的直接信息交流和控制通路,帮助我们突破身体局限,增强人体机能。脑机接口技术将人的延展方式和水平提升至了一个新的境界,为人类认识自己开辟了新的维度。作为一种革命性的人机交互方式,脑机接口延展了人类身份的范畴,使人机混合体的赛博格身份成为可能;它延展了人类身体的边界,使超越身体局限的梦想成为可能;它延展了人类实践的方式,使意念控制的愿景成为可能。脑机接口技术在造福人类展现高价值的同时,也难免存在着高风险,其价值负载和伦理挑战越来越为人们所关注和重视。

     

Reconsidering the path for neural and physiological methods in consumer psychology

Recent decades have witnessed a burst of neuroscience research investigating mental and physiological processes central to consumer behavior, including sensory perception, memory, and decision making. Nonetheless, few publications that include neural and physiological measures, or develop conceptual frameworks around neuroscience principles, have been published in consumer psychology. It is clear that “consumer neuroscience” has thus far not lived up to its promises in the marketing literature. We suggest three main reasons for this. First, neural and other biological markers are often mistaken to be identical to the overlaying psychological constructs in traditional consumer psychology work. Second, somewhat surprisingly, there has been an overly narrow utilization of neural data. Most previous work focused on linking existing behavioral phenomena or psychological constructs central to consumer research to neural correlates using brain imaging techniques while ignoring other methods. We argue that much can be gained from improved integration of physiological measures and through them, different levels of analysis. Third, there remain significant structural hurdles to the broad adoption of neural and physiological measures for consumer researchers. We outline how addressing these three components can translate to a more holistic understanding of the consumer via both broader and deeper consumer insights.
