This study investigated longitudinal relations between measures of neonatal state behavior and developmental outcome in a sample of preterm infants (N = 16). Results indicate that irritability/reactivity in the neonatal period is positively associated with Bayley scores and exploratory play at 8 months. Conversely, neonatal alertness was not associated with these developmental measures. These preliminary findings, based on a small sample, are discussed in the context of preterm function. 相似文献

The credible intervals that people set around their point estimates are typically too narrow (cf. Lichtenstein, Fischhoff, & Phillips, 1982). That is, a set of many such intervals does not contain the actual values of the criterion variables as often as it should given the probability assigned to this event for each estimate. The typical interpretation of such data is that people are overconfident about the accuracy of their judgments. This paper presents data from two studies showing the typical levels of overconfidence for individual estimates of unknown quantities. However, data from the same subjects on a different measure of confidence for the same items, their own global assessment for the set of multiple estimates as a whole, showed significantly lower levels of confidence and overconfidence than their average individual assessment for items in the set. It is argued that the event and global assessments of judgment quality are fundamentally different and are affected by unique psychological processes. Finally, we discuss the implications of a difference between confidence in single and multiple estimates for confidence research and theory. 相似文献

Gender displays in portrait photographs 总被引:1,自引:0,他引:1
Janet Mills Ragan 《Sex roles》1982,8(1):33-43
Following the research of Goffman (1976) and Henley (1977) on sex differences in nonverbal behavior, 1,296 portrait photographs from high school and university yearbooks and from the media files of a university were analyzed for sex differences. Females smiled with a significantly greater frequency and expansiveness than males and head canted significantly more than males. Results supporting the hypothesis that males would face the camera more directly than females failed to reach the acceptable significance level. The prediction that persons working in opposite-sex roles would deintensify their gender displays failed to gain support.The author expresses appreciation to Bill Drell and Andrea Wilson for their assistance in data collection. 相似文献

This study examines the effects of (1) generality equivalence between attitudinal and behavioral entities and (2) the order and proximity of the attitude and behavior questions on the observed relationship between attitudes and behavior. The behaviors examined are sentence recommendations for six hypothetical defendants. The sample is composed of 185 line probation officers from New York State. The variables chosen conform to Martin Fishbein's model of behavioral intentions. As predicted, the observed relationship is affected by both level of specificity and proximity of the questions. Order of the questions has little effect. 相似文献

The apparently divergent similarity-attraction findings of the reinforcement theory and uniqueness theory researchers were investigated by exposing male (N = 45) and female (N = 45) subjects to conditions of slight, moderate, or high similarity relative to one comparison other. Similarity was manipulated by means of a bogus personality and attitude inventory. For the self-report measures, results consistent with reinforcement theory were obtained in that greater self-reported attraction to the partner was linearly related to increased similarity. Additionally, interpersonal distance was curvilinearly related to similarity. This distancing pattern reflected the fact that moderate similarity subjects positioned themselves relatively closer to the other person's chair than the slight or high similarity subjects. The physical distance results support the uniqueness theory notion that high similarity may have some aversive properties. The discrepancy between the physical distance and self-report results is discussed in terms of an implicit causal theory that subjects may have about interpersonal similarity (i.e., greater similarity is good). 相似文献

Orthography and familiarity effects in word processing 总被引:1,自引:0,他引:1

Both orthographic regularity and visual familiarity have been implicated as contributors to the efficiency of processing visually presented words. Our studies sought to determine which of the internal codes representing words in the nervous system are facilitated by these two variables. To do this, sets of letter strings in which orthography and familiarity were factorially combined were used as the basis for physical, phonetic, semantic, and lexical judgments. The data indicated consistent effects of orthography on the activation of all codes. These effects were seen in same-different matching and in judgments of stimulus orientation, which are based on visual codes; in judgments of pronounceability based on phonetic codes; in judgments of meaningfulness based on semantic codes; and in lexical decisions, which are based on phonetic and semantic codes together. Familiarity, on the other hand, had a clear influence on the activation of semantic codes and to a lesser extent affected phonetic codes. Despite previous positive results found in matching letter strings, however, no influence of familiarity occurred in judgments based on visual codes once evidence for criterion shifting was eliminated. Our negative results included direct tests of facilitation in matching acronyms (e.g., FBI) and in matching both regular and irregular strings familiarized by specific training. It now appears that earlier findings of visual familiarity effects may be attributed to response biases resulting from the activation of higher level codes sensitive to familiarity, and to the use of small sets of training stimuli that allowed subjects to induce orthographic-like rules. The results obtained so far with our methods seem to reconcile an inconsistent literature by showing that speeded decisions based on visual codes are most strongly influenced by rule-governed processing mechanisms sensitive to orthographic structure, whereas decisions based on phonetic and semantic codes are affected about equally by rule-governed mechanisms and by stimulus-specific mechanisms sensitive to familiarity. This conclusion may lead to changes in notions of how effective various kinds of visual training are likely to be at different stages in the acquisition of reading skill. 相似文献
