Mosher and Bond (this issue) suggest experimental designs that are not appropriate for the research purposes they criticize. In defending their own research, they make contradictory statements about the realism of their guided imagery procedure for simulating rape. They present data that we believe provide evidence for the possibility that wrongful harm occurred in their previous research. We assert our right to study the ethics of research and object to specious charges of having threatened sexual freedom and being associated with ideologues of the right and left. 相似文献

Abstract— Across two studies comparing younger and older adults, age differences in optimal performance periods were identified (Study 1), and then shown to be an important determinant of memory differences (Study 2). A norming study showed that while most younger adults were Evening or Neutral types, as determined by a standard questionnaire, the vast majority of older adults were Morning types. A second study compared the recognition performance of younger and older adults tested in the morning or in the late afternoon. Substantial age differences were found in the late afternoon, when younger but not older adults were at their optimal times. However, no age differences in memory performance were found in the morning, when older but not younger adults were at their peak period. Thus, synchrony between optimal performance periods and the time at which testing is conducted may well be a critical variable in determining group differences in intellectual performance, particularly between older and younger adults. 相似文献

Our purpose in this research was to determine the extent to which computer-based instruction can replace conventional teaching in experimental psychology. In Experiment 1, students from an advanced cognition and thinking course participated in a simulation of Schallert’s (1976) study of the role of context in prose comprehension and in a simulation of Carpenter and Just’s (1975) study of sentence-picture verification latencies. Half of the students completed each experiment with the computer, and half were taught traditionally. Comprehension of the purpose and design of the experiments was tested immediately after the laboratory session and 1 month later during the final examination. There were no significant differences between the groups. Several students in Experiment 1 appeared to rush through the experiments and pay little attention to the explanations. In Experiment 2, we studied the effectiveness of computer-based instruction in experimental laboratory sections that did or did not require a follow-up assignment. The second variable was introduced so that some factor of seriousness or importance of the laboratory exercise could be measured. Results from this study indicated that, regardless of the perceived importance of a laboratory exercise, students who studied classic research in a traditional setting comprehended the purpose and design of the experiment better than did the students who worked on the computer. In addition, the students assigned to write up the experiment performed better than did the students who were given no follow-up assignment. 相似文献

In the author's own words: I am a cancer patient involved in an agonizing struggle against disease. I decided to write about the humiliating aspects of cancer because I have experienced them firsthand. I know them all too well. I have incorporated my feelings about the humiliation of disease ... hoping they may help the reader better understand.Cynthia McGinnis Richards died of Hodgkin's Disease in February 1988. 相似文献

Two experiments asked whether listeners can judge word rate from a speech signal that has been degraded in various ways. In the first, the rates of spontaneous speech were increased by 42% and further transformed to produce tone-silence sequences. The tonesilence sequences were presented to listeners who judged the rate of each sequence. Results clearly indicated that listeners could differentiate the rates of the tone-silence sequences, suggesting that minimal nonlinguistic information may be sufficient to make grossly accurate estimates of speech rates. In the second study, listeners were presented with speech sequences involving three naturally produced rates (slow, moderate, and fast) in three conditions (clear, frequency-inverted, and tone-silence) such that different listeners participated in the three conditions, but heard all rates in each condition. Listeners in the clear and frequency-inverted conditions distinguished all three rates, but those in the tone-silence condition differentiated only the slow and moderate rates. Contrary to expectation, the gender and extroversion scores of the listeners did not affect their judgments. 相似文献

This study is an attempt to determine whether (a) the gender of a young child would elicit differential academic beliefs from individuals who aspire to become parents and teachers; and (b) male and female individuals who aspire to become parents and teachers have differential academic beliefs about young children. Data from 108 university students who intended to become parents and teachers showed that the gender of a young child elicited differential academic beliefs, and that male and female aspiring parents and teachers tended to have different academic beliefs about young children. The findings are discussed in terms of the relationship between stereotyped socialization practices and differential achievement between the two genders. Implications of the findings for education are noted.An earlier version of this paper was presented at the annual meeting of the Midwestern Educational Research Association in Chicago, Illinois, October 1988. The helpful comments of a review editor are most gratefully acknowledged. 相似文献

A set of four facial stimuli derived from the Bolton standards of craniofacial development representing a human male at 6 months, 3, 8, and 18 years of age were used in a test of Lorenz's concept of babyishness and of the discrepancy hypothesis. Each 4-month-old subject was habituated to a criterion with one of the four stimuli and then presented with one of the four as a new stimulus. The design and analysis permitted the response to a new stimulus to be broken down into a component attributable to the physical characteristics of the new stimulus and a part attributable to its discrepancy from the familiar standard. The data revealed longer looking at the infant facial stimulus, but no difference in a rating of affect accompanying fixation. This lent partial support to the babyishness concept for infant subjects. Both fixation and affect increased monotonically with magnitude of discrepancy. The increasing rather than curvilinear result presumably derived from the failure of these stimuli (which were common to the infant's experience) to generate extreme levels of subjective uncertainty. 相似文献

Two experimental paradigms were used to investigate the interference which occurs in a choice RT task when the source of a stimulus does not correspond with its meaning. In one paradigm, subjects were instructed to delay executing their response to a red or green light until they heard a go signal which was presented 0, 150,250, or 350 msec after the light. In the other paradigm, subjects translated the pitch of a tone into an appropriate keypress response. For some groups, the stimulus response connections were specified prior to or simultaneously with the presentation of the stimulus tone, while, for other groups, the labeling of the response keys followed the onset of the tone. Results indicated that irrelevant directional cues produce interference which affects the response selection stage and persists for approximately 250 msec 相似文献

Studied performance on a multiple-solution anagrams task by two-member nominal, pseudo, quasi, and real groups in relation to task conditions (set versus nonset) and school grades (10th, 11th, and 12th). Nominal groups were made up of individuals working alone. Pseudo groups were made up of members sitting together but working independently for individual scores. Quasi groups were made up of members who were working together for a common or shared goal but were not allowed to communicate with each other. Real groups were the usual teams of freely interacting and mutually consulting members. Five words were presented to the subjects in the set condition (unlike in the nonset co ndition) in order to channelize their problem-solving activity in particular directions. The subjects were 192 male American high school students. The most important finding was that both nominal and pseudo groups produced more errors than real groups. Also the set condition generated more errors than the nonset condition. These and other findings were discussed and interpreted in the context of previous research. 相似文献
