An eye fixation analysis of choice and judgment with multiattribute stimuli

The present paper examined the selection of processing heuristics for choice and judgment across a range of stimuli. Eye fixations were monitored while six subjects made choices or judgments of pairs of gambles, vacations, or gifts. Each stimulus was represented by three attributes that varied in the amount of dimensional interdependency. The two heuristics of interest were dimensional and holistic evaluation. Each manifested a characteristic pattern of eye fixations. Dimensional evaluation required alternating fixations from a single attribute of one stimulus to the same attribute of the other stimulus. Holistic evaluation was characterized by transitions from attribute to attribute within a single stimulus. The results demonstrated that when the stimulus attributes were either interdependent (gambles) or dissimilar (gifts), the processing heuristic was determined by stimulus characteristics. When the stimulus dimensions were neither interdependent nor dissimilar (vacations), the selection of a processing strategy was determined by the prescribed task. This study suggests that any global theory of choice or judgment must be validated over a wide range of stimuli.     

Tolerance for ambiguity and self-actualization

This study was designed to test the hypothesis, implicit in several areas of previous research, that high tolerance for ambiguity is a cognitive style which reflects high levels of underlying psychological health. Using Self-Actualization scores on the Tennessee Self Concept Scale, 36 adult subjects were defined as relatively high or low in self-actualization with equal numbers of males and females in each group. All subjects then performed individually on the Rorschach test and the Rorschach protocols were rated reliably for degree of tolerance for ambiguity. It was found that regardless of sex the high self-actualization group exhibited a significantly higher level of tolerance for ambiguity than the low self-actualization group. The finding was interpreted as confirmation of the study's hypothesis.     

工作家庭冲突的初步研究

工作家庭冲突是一种特殊类型的角色交互冲突 ,它对于了解人的胜任特征模型和提高人力管理的效率有重要的意义。本研究通过在银行、科研单位和高新技术企业进行的有关工作家庭冲突的调查结果表明 ,较之家庭—工作冲突 ,工作—家庭冲突能较好预测员工的工作压力 ,它通过工作压力间接地对工作满意感起作用 ,女性员工的工作态度更容易受到工作—家庭冲突的影响。     

阅读中自然学习生词的实验研究

本研究对儿童阅读时从语境中自然学习生词的过程及其多个影响因素进行了探讨。301名三、五年级小学生参加了实验。首先要求他们阅读文章,然后测验他们对文章中生词的知识。本研究在不同年级和能力的儿童中都发现了显著的自然学习效应。结果还表明,词的概念难度、词结构的语义透明度、语境线索强度和儿童课外阅读量对儿童的自然学习有重要影响。     

领导-部属交换的多维结构及对工作绩效和情境绩效的影响

通过两项研究,对领导-部属交换的结构及其对员工的工作绩效和情境绩效进行了探讨。采用探索性因素分析、验证性因素分析、分层回归分析等方法对来自不同企业的员工及其主管的问卷调查结果进行了分析。 结果表明,领导-部属交换是一个多维度的结构,由情感、忠诚、贡献和专业尊敬四个维度组成。单维度的领导-部属交换和多维度的领导-部属交换都对员工的工作绩效和情境绩效具有预测作用,但多维度领导-部属交换的预测作用更强。     

男性择偶策略改变的前提：自感配偶价值提高

研究分为问卷调查与实验研究两部分。首先,40名女性和33名男性完成有关自感配偶价值评价（SPMV）和择偶偏爱策略的问卷调查,问卷调查结果是实验研究中数据分析的基线。其次,第二部分实验开始后,被试会得到实验者编造的他人潜在择偶对象的积极正面评价,其目的在于提高被试的SPMV。可以假设,男性的SPMV与随意性行为的认同或追求有正相关,男性SPMV的提高将会更加偏爱短期的性策略;女性SPMV与随意性行为不存在相关,女性SPMV的提高不会改变女性的性策略。研究结果显示,SPMV高基线水平的男性更加认可随意性行为,男性SPMV的提高与短期策略选择的增加有关。另外,SPMV提高,而不是一般自尊的提高,与择偶策略的改变具有相关。本研究结果没有证实,与长期稳定的性关系相比,SPMV的基线水平或是提高与女性对随意性行为的认同或追求之间存在相关
