Previous research has shown that preferences for options, such as gambles, can reverse depending on the response mode. These preference reversals have been demonstrated when tasks were performed sequentially. That is, subjects completed one task before beginning another. In an attempt to eliminate preference reversals, we asked subjects to perform tasks simultaneously. That is, subjects made two types of responses for each pair of gambles before evaluating the next pair. In the condition with no financial incentives, preference reversal rates were slightly reduced. In another condition, subjects were paid for their participation and they were allowed to play a gamble with real monetary compensation. A gamble pair was randomly selected, and if a subject's responses in the two tasks were consistent for that pair, he or she was allowed to play the ‘preferred’ gamble. Otherwise, the experimenter selected the gamble from the pair. With these financial incentives, systematic preference reversals were eliminated for two of the three task combinations. Preference reversals continued to occur for attractiveness ratings versus selling prices, although, even for that pair of tasks, the reversal rate was significantly reduced. For all three task pairs, preference orders from the two tasks appeared to merge into more consistent orders. 相似文献

Subjects viewed a foveally stabilized target presented against a background field of dots moving sinusoidally. Several different modes of viewing the target were used (subjects were instructed to gaze, look, or hold), and the frequency of sinusoidal field motion was varied from 1/32 to 2 Hz. In line with previous findings, the presence of a stabilized target resulted in substantial suppression of optokinesis. The characteristics of this suppression (gain and phase of slow residual eye movements) were dependent on both the mode of viewing the target and the frequency of field motion. When subjects used an imaginary target, little suppression occurred. These findings provide an overall profile of dynamic characteristics of mechanisms involved in the suppression of optokinesis. They support the view that this suppression is significantly determined by the presence of a target against a moving background (even without retinal slip), and by the mode of attending to the target. 相似文献

The Relational Health Indices: A Study of Women's Relationships 总被引:1,自引:0,他引:1

A new measure of women's relationships, the Relational Health Indices (RHI), comprises three scales that assess growth-fostering connections with peers, mentors, and communities. The RHI was developed using the Relational Model (Jordan, Kaplan, Miller, Stiver, Surrey, 1991; Miller & Stiver, 1997), a theory of women's psychological development. The 37-item measure assesses three conceptual dimensions of growth-fostering relationships: engagement, authenticity, and empowerment/zest. This study examined the psychometric properties of the RHI with a group of 450 students at a women's liberal arts college, providing evidence for the reliability, validity, and utility of the new measure. The factor analyses confirmed a three-subscale structure: engagement, authenticity, empowerment/zest. The RHI's components generally demonstrate good overall internal consistency. Furthermore, associations between RHI scales and convergent validation scales were significant and in the direction hypothesized. Correlations with adjustment scales varied across the RHI components. The RHI has potential for enriching our understanding of important, subtle qualities and complex dynamics of both dyadic and group relationships, especially among women. The instrument is available for use by researchers interested in continuing the scale and theory development. 相似文献

Intersensory redundancy can facilitate animal and human behavior in areas as diverse as rhythm discrimination, signal detection, orienting responses, maternal call learning, and associative learning. In the realm of numerical development, infants show similar sensitivity to numerical differences in both the visual and auditory modalities. Using a habituation-dishabituation paradigm, we ask here, whether providing redundant, multisensory numerical information allows six-month-old infants to make more precise numerical discriminations. Results indicate that perceptually redundant information improved preverbal numerical precision to a level of discrimination previously thought attainable only after additional months of development. Multimodal stimuli may thus boost abstract cognitive abilities such as numerical competence. 相似文献

Traditional self-report ratings have some measurement problems that a relatively new method, best-worst scaling (BWS; Finn & Louviere, 1992), may overcome. This alternative method, based on Louviere's BWS, can be used to measure the relative importance or perceived trade-offs among choice alternatives. The method is illustrated as an alternative to the Schwartz Value Survey (SVS; Schwartz, 1992). In a series of samples, it was found that Schwartz values best-worst survey (SVBWS) reproduced Schwartz's (1992) theoretical value structure and supported hypothesized relationships between values and value-expressive behaviors, ethnocentrism, and environmental-related tourism activities. In addition, the SVBWS approach took significantly less respondent time than the traditional SVS approach. 相似文献

Research examining the association between self-esteem (SE) and aggressive behavior in childhood has produced mixed findings. Some of the confusion may stem from the fact that researchers have relied on explicit measures of SE, thus conflating two distinct types of positive self-regard: secure SE (characterized by high levels of explicit and implicit SE), and defensive SE (characterized by high levels of explicit but low levels of implicit SE). The current study tested the hypothesis that children with high levels of defensive, but not secure, SE would engage in higher levels of aggressive behavior. Ninety-three children completed measures of both explicit and implicit SE. Teachers assessed children’s level of physical and relational aggression in the school setting. As predicted, there was a positive association between explicit SE and aggression when levels of implicit SE were low, but not when levels of implicit SE were high. 相似文献

The development of language indicating the emergence of thinking about the thoughts of self and others has been scarcely studied in Spanish-speaking children. For this reason, we studied the development of mental state language and various indicators of language development in 25 Spanish-speaking children assessed at 3, 3 1/2, 4, 4 1/2, and 5 years of age. We coded and categorized the 40,250 utterances children produced during the five time points, 1202 (3.01%) of which had mental terms. In this sample, mental state language in Spanish children developed with a similar timeline and patterns as described in English-speaking children. However, several findings were novel for studies of mental state language. The general indexes of syntactic development did not correlate with the production of mental terms. The Index of Lexical Diversity was associated with the frequency of references to verbs of desire. The results of regression analyses suggest that not only the development of subordinate sentences with complement is associated with genuine mental references to desires and beliefs, but the development of lexical skills as well. 相似文献

Background Previous research has produced conflicting results regarding the effects of season of birth and age‐position on cognitive attainments. In Northern Ireland the school year divides the summer season into two providing an opportunity to evaluate the relative contribution of season of birth and age‐position effects. Aims To investigate the relationship between attainment in literacy skills and month of birth for primary and secondary school pupils and to determine the relationship between motor skills and month of birth in primary school pupils. Sample One thousand one hundred and twenty four primary school pupils participated, and results for key stage 3 (KS3) English and GCSE English Language, for 3,493 Year 10 and 3,697 Year 12 secondary school pupils, respectively, were obtained. Method Primary school pupils were individually assessed using standardised reading and spelling tests, as well as tests of motor skill. They were also assessed using a standardised group reading test in their class groups. For the secondary school pupils, the results for two year cohorts, in KS3 English and GCSE English language, respectively, were analysed. Results For the primary school pupils there was evidence of both a season of birth and an age‐position effect on all of the cognitive measures, particularly in the early years of schooling. There was, also, evidence of a significant age‐position effect at both KS3 and GCSE in favour of the older pupils. For the younger primary school pupils there was evidence of significant age‐position effects on both motor measures. Conclusions The findings from the present study suggest that month of birth may be related to both season of birth and age‐position effects. These effects may be compounded, particularly in the early years of primary school, when summer born children are youngest in their year, as in England. In Northern Ireland, age‐position effects are also evident in secondary school public examination results, which may have implications for long‐term life choices. 相似文献
