This study uses data collected using a 360°-assessment instrument to investigate the structural equivalence of 360°-assessment ratings, according to rater type, controlling for organizational level. Data from 533 managers and their raters were employed in the study, which used multi-group structural equations modeling. Issues central to the implementation and use of 360°-assessment data are also considered within the context of current research and practice. 相似文献

Recent interest in the nature of grounding is due in part to the idea that purely modal notions are too coarse‐grained to capture what we have in mind when we say that one thing is grounded in another. Grounding not being purely modal in character, however, is compatible with it having modal consequences. Is grounding a necessary relation? In this article I argue that the answer is ‘yes’ in the sense that propositions corresponding to full grounds modally entail propositions corresponding to what they ground. The argument proceeds upon two substantive principles: the first is that there is a broadly epistemic constraint on grounding, while the second links this constraint with Fine's Aristotelian notion of essence. Many think grounding is necessary in something like the sense specified above, but just why it's necessary is an issue that hasn't been carefully addressed. If my argument is successful, we now know why grounding is necessary. 相似文献

The goals of this research were to determine whether speakers adjust the stress patterns of words within sentences to create an alternation between strong and weak beats and to explore whether this rhythmic alternation contributes to the characteristics stress differences between two major lexical categories of English. Two experiments suggested that speakers do alter lexical stress in accordance with rhythmic biases. When speakers produced disyllabic pseudowords in sentence contexts, they were more likely to place stress on the first syllable when the pseudoword was preceded by a weak stress and followed by a strong one than when the strong stress preceded and the weak followed. This occurred both when the pseudowords served as nouns and when they served as verbs. Text analyses further revealed that weakly stressed elements precede nouns more often than verbs, whereas such elements follow verbs more often than nouns. Thus, disyllabic nouns are more likely than disyllabic verbs to occupy contexts biased toward trochaic rhythm, a finding consistent with leftward dominant stress in disyllabic English nouns. The history of stress changes in English nouns and verbs also conforms with the view that rhythmic context may have contributed to the evolution of stress differences. Together, the findings suggest that the citation stress patterns of words may to some degree reflect adaptations of lexical knowledge to conditions of language performance. 相似文献

This paper explores the notion of truthfulness in research on conversational remembering. It argues that people's accounts of past events, before they can be taken as data on the cognitive workings of memory, need to be examined as contextualized and variable productions that perform pragmatic and rhetorical work; no one version can be taken as a person's real memory. The consequences of this discourse-analytical perspective are examined first through a critical discussion of Ulric Neisser's study of John Dean's testimony to the senate ‘Watergate’ committee. The issues are then explored more deeply in an analysis of reportings of a different event, in which similar (Watergate-like) issues of memory, truth and accuracy are also at issue. It is argued that: (a) all of Neisser's three kinds of memory–verbatim, gist and ‘repisodic’–involve problematical assumptions concerning their relation to some true, original event; and (b) that Dean's accounts of his memory and his displays of memory should be approached as occasioned productions oriented pragmatically to the assignment of guilt and avoidance of scapegoating. Through an analysis of newspaper reports (based on memory) of a controversial briefing given by the then British Chancellor of the Exchequer, Nigel Lawson, we then examine: (a) how discourse about what could be used as an arbiter of truth was rhetorically organized; (b) how participants' versions of events were constructed rhetorically, as parts of arguments; (c) that both sides in the dispute maintained the coherence of their positions by a form of error accounting similar to that used by Neisser with respect to Dean. It is suggested that cognitive psychologists, whether working in the laboratory or attempting to do real-world studies of everyday remembering, need to avoid simplistic notions of true original events, and can do so by addressing the rhetorical organization of participants' memory accounts. 相似文献

Ambient white noise (80 dB), compared with quiet (52-dB) testing conditions, improved the performance of elderly and younger subjects on simple addition. Reliable age-related interactions were found on health measures of systolic and diastolic blood pressure, as well as heart rate. Heightened sensory conditions reduced the physiological measures of arousal in the younger group, whereas significant cardiovascular reactivity was found among the older group. The results are suggestive of the potential for increased cardiovascular risk as a function of sensory stimulation in the elderly despite improvements on cognitive tasks. Additional research is needed to evaluate the multidimensional effects of extended sensory stimulation on the elderly. 相似文献

This investigation examined the relationship between methylphenidate (MPH) and the learning and recall of paired associations by children with attention deficit disorder with hyperactivity (ADDH). Forty-five children with ADDH were randomly assigned to one of three groups (novel, partial mastery, and mastery learning) that varied in the amount of previous learning of paired associations and participated in a double-blind, placebo-control, repeated-measures-across-dose (crossover) design. Each child received four doses of MPH (5 mg, 10 mg, 15 mg, and 20 mg) and a placebo in a random, counterbalanced sequence. The results indicated that both the rate of acquisition and accuracy in learning paired associations were significantly, but differentially, affected by MPH dose and the degree of learning mastery. The implications of these results for psychopharmacological research and the monitoring of psychostimulant effects on children's learning performance in academic settings are discussed.The authors wish to acknowledge and express their sincere appreciation to the graduate and undergraduate student members of the Children's Learning Clinic. 相似文献
