Ray Over 《Australian psychologist》1982,17(2):129-139
The research productivity of psychologists holding appointment in Australian universities was established at two times of measurement across groups defined with respect to chronological age and date of birth. The design allowed cross-sectional gradients to be contrasted over times of measurement, and longitudinal gradients to be compared across cohorts. Psychologists aged 26–35 years in 1970 showed no decline in publication rate between 1968–1970 and 1978–1980, while psychologists aged more than 35 years in 1970 showed a drop in research output over the 10-year period. However, a person's publication rate in 1978–1980 was better predicted by their past productivity (publication rate in 1968–1970) than by their age. These results are discussed in the context of factors that affect research productivity, as well as changes that will occur in the age distribution of Australian academics over the next 20 years. 相似文献

Early sexual explorations of children that are of a traumatic nature are often labeled by the child as bad or wrong and subsequently repressed. The guilt that results from the labeling may be intensified at a later date by some other similar incident, and at this time the person may make a binding commitment or promise to God to serve Him in some dutiful way. If, at a later date, these plans to serve God cannot be realized, depression, phobias, or conversion symptomatology may occur, which we have referred to as the Missionary Syndrome.Ray O.

Does the administrator of a test have an effect on the results of a group taking a test? If so, does a warm positive administrator have a different effect than a cold aloof examiner? Is there a difference in the effect of a male and female administrator? These are the questions that this study was designed to investigate. One hundred forty females 22 years or over taking the clerical battery of the GATB as part of a civil service examination were randomly assigned to one of three test administrators: (1) a warm, positive administrator, (2) a neutral administrator and (3) a negative, aloof and unhelpful administrator. One male and one female employed each of the experimental treatments resulting in six treatment groups. Findings: (1) Subjects taking the test administered by males did not achieve significantly different scores from those taking the test administered by females; (2) Warm positive administrator behavior produced significantly higher scores than negative administrator behavior; (3) Neutral administrator behavior produced significantly higher scores than negative administrator behavior; (4) Neutral and positive administrator behaviors were on the average equally effective in promoting high scores. 相似文献

Four rhesus monkeys learned both a color and tilt discrimination. The stimuli were combined to produce incompatible behavior. The behavior controlled by one set of stimuli was reinforced until “errors” virtually disappeared. The stimuli were tested separately again. Sixteen replications of the entire procedure indicated that the stimuli producing “errors” were ignored. 相似文献

The finding that Pavlovian signals for food or shock influence avoidance responding might be explained either by interaction of conditioned central mediational states or interaction of learned instrumental responses. Using three groups of dogs, the two hypotheses were pited one against the other in a three-stage transfer-of-control experiment. In the initial conditioning phase, tones were established as signals for food, shock, or neither; additionally the tones also cued a common instrumental response. Following avoidance training, the tone was tested for its influence upon avoidance. If the lone had signaled food, avoidance was suppressed; if shock, avoidance was facilitated; if neither, avoidance was unaffected. This was interpreted as supporting the hypothesis that interaction of central states mediates the transfer-of-control. 相似文献

Indexes of skewness and kurtosis for a test-score distribution are expressed in terms of item parameters. Both are shown to depend, in part, on item means, variances, and covariances. The index of skewness depends also on trivariances. A trivariance is a product moment involving first powers of deviation scores for three items. The index of kurtosis depends on quadrivariances, as well as trivariances. A quadrivariance is a product moment involving first powers of deviation scores for four items. Empirical data are presented for responses of groups of subjects to 25 triads and 25 tetrads of items from five tests.Certain parts of this article represent the results of doctoral research conducted by Hundleby and Goldstein under the direction of Ray in the Department of Psychology at Pennsylvania State University. The authors are indebted to Professor Lester Guest and Professor William Lepley for their supervisory assistance in the final stages of the two dissertations during the absence of the senior author. 相似文献

Each of four groups of monkeys were trained on a different simultaneous discrimination procedure involving a vertical line as the correct choice. Each group, after acquiring the discrimination, was tested for generalization along the dimension of line tilt. Monkeys that learned to select the vertical line when the alternative choices were distinguished from the correct choice by two aspects (brightness and absence of line) showed almost complete tilt generalization (flat gradient). Monkeys that learned to select the line when the alternatives were distinguished only by the absence of the line showed poor tilt discrimination (generalization gradient slightly peaked at vertical). Monkeys developed a good tilt discrimination when nonvertical lines were gradually introduced by progressively darkening them on the previously blank alternatives. Monkeys developed a tilt discrimination with the lowest error rate when only horizontal alternatives were gradually introduced and then pairs of alternatives progressively closer to vertical were made available. 相似文献
