In contrast to prospective power analysis, retrospective power analysis provides an estimate of the statistical power of a hypothesis test after an investigation has been conducted rather than before. In this article, three approaches to obtaining point estimates of power and an interval estimation algorithm are delineated. Previous research on the bias and sampling error of these estimates is briefly reviewed. Finally, an SAS macro that calculates the point and interval estimates is described. The macro was developed to estimate the power of anF test (obtained from analysis of variance, multiple regression analysis, or any of several multivariate analyses), but it may be easily adapted for use with other statistics, such as chi-square tests ort tests. 相似文献

Several recent studies have investigated relationships between post-traumatic stress disorder (PTSD) and learning and memory
problems. These reports have found in general that not only does PTSD affect trauma-related memories, but when patients with
PTSD are compared with similar trauma patients without PTSD, general memory impairments have been found. The present paper
reports a study in which associative learning, using Pavlovian eyeblink conditioning, was investigated in combat veterans
with and without chronic PTSD, using interstimulus intervals of 500 and 1000 msec in two separate experiments. Although several
recent reports suggest that larger-magnitude autonomic conditioned responses occur in patients with PTSD during Pavlovian
conditoning, the present study found evidence of impaired Pavlovian eyeblink conditioning in combat veterans with and without
PTSD, compared to non-combat veterans. Although these data suggest that combat leads to an impaired associative learning process
regardless of whether PTSD is apparent, a group of community-dwelling combat veterans not under medical treatment showed normal
conditioning, suggesting that variables other than prior combat must also be involved. 相似文献

The effect of multiple childhood sexual assaults on the believability of a repressed memory of the assault was assessed using mock jurors. Participants read a fictional civil trial summary about a child sexual assault case presented in one of three reporting conditions: (a) immediate condition-the alleged victim testified immediately after the assault(s); (b) repressed condition-the alleged victim reported the assault(s) 20 years later, after remembering it/them for the first time; or (c) no-repressed condition-the alleged victim reported the assault(s) 20 years later, but the memory of the assault(s) had been present for those years. The number of assaults was either one or 30. The results showed that for all reporting conditions 30 alleged assaults led to relatively more decisions for the plaintiff than the defendant, and greater believability of the plaintiff. The increases in decisions rendered and believability were also generally true for the immediate condition compared to when there was a delay in reporting. The results are discussed in terms of mock jurors' perceptions of child sexual assault, both those reported immediately and those reported after many years. 相似文献

Distinguishing Language from Thought: Experimental Evidence That Syntax Is Lexically Rather Than Conceptually Represented 总被引:1,自引:0,他引:1

It is generally assumed that syntax is represented linguistically rather than conceptually, consistent with the more general view that language and thought are coded separately. This claim is widely defended on logical grounds, but it has received little experimental support. In the present study, we asked Spanish and English speakers to make semantic and syntactic categorizations for pictures and their corresponding names. Consistent with past results, latencies to semantically categorize pictures and words were similar. The new finding is that participants were faster to make syntactic decisions for words compared with pictures, suggesting that syntactic features such as grammatical gender and the count-mass distinction are more closely linked to lexical than conceptual representations. 相似文献

As the religious diversity of English towns and cities has grown over the past thirty years due to the establishment in some places of sizeable communities of Hindus, Muslims and Sikhs, as well as other faiths, there have been important changes to local public religion. Traditional civic ceremonies, such as Remembrance Sunday, as well as new forms of civic celebration and commemoration, are now increasingly taking account of the diversity of faiths represented in Britain. This paper examines the consequences of religious diversity for English civic religion by looking at some of the traditions of civic ceremonies in England and at the way in which they have been transformed by the changing religious landscape of towns and cities. The paper also explores some of the dilemmas and questions that have emerged both for the Church of England as well as for the other faith communities when it comes to the design and delivery of civic ceremonies. 相似文献

In this paper, I introduce and examine the notion of “mathematical engineering” and its impact on mathematical change. Mathematical engineering is an important part of contemporary mathematics and it roughly consists of the “construction” and development of various machines, probes and instruments used in numerous mathematical fields. As an example of such constructions, I briefly present the basic steps and properties of homology theory. I then try to show that this aspect of contemporary mathematics has important consequences on our conception of mathematical knowledge, in particular mathematical growth. 相似文献
