Students representing the top 0.03% of their age group in intellectual ability, who were identified by the Study of Mathematically Precocious Youth (Benbow & Stanley, 1980), were tested along with their parents using a battery of specifically designed cognitive tests. These highly intelligent children had less intelligent, but yet quite bright parents. Vernon's (1961) model of intelligence best fits our results. His following two factors explained most of the variance in the performance of the students and parents: verbal-educational and practical-spatial-mechanical. Moreover, there was potential evidence for a general factor. Among the children, who were mostly past puberty, age related to development of verbal abilities, but not spatial or mechanical abilities. Sex differences favoring the males were found on the spatial ability and mechanical comprehension tests. 相似文献

A test of Holland's vocational theory across and within selected occupational groups demonstrated concurrent validity for three of the four groups investigated. Statistically significant coefficients of concordance indicated a degree of agreement among individuals in each of the occupational groups investigated. Statistically significant Page's L statistics indicated that a degree of agreement between the theoretical ordering and the observed ordering of the six types or themes was obtained on three of the four groups tested. 相似文献

Content analyses of crime coverage in the news media (e.g., Graber, 1980) consistently demonstrate the overrepresentation of crimes of violence. It was hypothesized that in addition to direct effects upon members of the public (e.g., leading people to overestimate the number of violent crimes) this would also have several indirect effects. Reading about crimes of high seriousness might lead the public to (a) view other offenses more seriously, (b) regard other offenders more negatively, (c) punish other offenders more severely, and (d) emphasize the importance of retribution as a sentencing goal. Two experiments were conducted, using 90 members of the general public as subjects, to test these hypotheses. In Experiment I, subjects first read a news story about a crime that was of high, medium, or low seriousness. Later they rated an unrelated offender and offense more negatively, and were more punitive in their sentences, if the earlier offense had been very serious. There was equivocal support for the hypothesis that changes in punitiveness are caused by subjects shifting to a punishment-oriented sentencing strategy. Rather, it would appear that harsher penalties resulted from changes in perceptions of offense seriousness. These findings are discussed, as are future research directions. 相似文献

Ss agree in attributing character traits to strangers’ photographs, but there has been no explication of what such labels imply. Presumably. trait names either mediate or reflect Ss’ expectations of such strangers" likely social behaviors: but that remains undemonstrated, and we may be able to study such physiognomy-tied expectations directly. Sampling problems confront trait studies and intention studies alike, but the present research showed that Ss’ expectations of a person’s behavioral intentions, as measured by alternative interpretations of short “scenarios,” were reliably influenced by that person’s photograph. 相似文献

Although correlational evidence of a positive relationship between participation in decision-making and satisfaction is relatively consistent, whether participation in decision-making has a causal effect on satisfaction remains unclear. The present research examined, through an organizational simulation in which high and low levels of participation in decision-making were manipulated, the causal effect of participation on satisfaction and productivity. The subjects were 128 male undergraduates randomly assigned to 32 four-person groups. Results of the experiment showed that participation in decision-making had a significant positive effect on satisfaction. In addition, the correlation between perceived influence and satisfaction was positive (r= .31). Contrary to theoretically derived predictions, participation had no impact on productivity. 相似文献

The present experiments address the issue of stimulus specificity in fear and avoidance learning. First, it was established that light stimuli are effective warning signals (WS) in shuttle avoidance. Then light stimuli were shown to produce conditioned suppression in the conditioned emotional response situation comparable to that produced by noise conditioned stimuli. Finally, the effectiveness of noise onset and noise offset as feedback signals was tested. This was assessed under conditions of immediate and delayed termination of a light WS. Delayed termination of a light WS interfered with avoidance learning and the introduction of noise offset as a feedback signal enhanced it. The only demonstration of stimulus specificity was the failure of noise onset to function as a feedback signal. 相似文献

Two experiments were used to compare the recognition memory of amnesic and normal subjects for intentionally encoded words (targets) and for incidentally encoded words that were meaningfully related to the targets and presented at the same time (interactive context). In both experiments the target recognition of the two groups was matched at a high level by presenting the amnesics with much shorter lists of words to remember. Experiment 1 compared 20 amnesics and their matched controls and showed that whereas the amnesics' recognition of the target words did not benefit significantly when they were presented together with their interactive context words (relative to their recognition when the target words were presented alone), that of the controls did. Experiment 2 compared 14 amnesics and their matched controls and showed that when patients and their controls were matched on their target word recognition in isolation, then the patients still showed worse recognition for the interactive context words. These effects were not found only in Korsakoff patients, and their size did not correlate with behavioural measures of frontal-lobe damage. It is concluded that amnesics may be more impaired at recognizing incidentally encoded interactive context than they are at recognizing target material, and this deficit may be an essential feature of the syndrome. 相似文献

Navigation in the Morris swim task as a baseline for drug discrimination: a demonstration with morphine 下载免费PDF全文
Ziegler D Keith JR Pitts RC Galizio M 《Journal of the experimental analysis of behavior》2002,78(2):215-223
A morphine versus saline discrimination was demonstrated using the Morris swim task as the behavioral baseline. The apparatus was a large circular pool filled with water made opaque by floating polypropylene pellets. Rats were placed in the tank in randomly selected locations (12 trials per session) and could escape by swimming to a platform submerged 2 cm below the surface. Morphine (5.6 mg/kg) or saline was injected prior to training sessions. The position of the platform in a given session depended on the drug condition, thus forming the basis for discriminative responding. Three of the 4 rats acquired the discrimination, as evidenced by direct swims to the condition-appropriate platform. Generalization probe sessions were conducted following acquisition. Probe sessions were preceded by injections of morphine (0, 1.0, 3.0, 5.6, or 10.0 mg/kg) and involved placing the rat in the pool for 1 min without a platform. Swim patterns revealed a gradient, with probe swimming more concentrated in the area of the morphine platform position after higher morphine doses. In addition, dose-dependent increases in the likelihood of swimming first to the morphine-associated platform location were obtained. These results illustrate the generality of drug discrimination across different behavioral procedures, and of particular interest with respect to spatial learning, demonstrate interoceptive stimulus control of navigation. 相似文献

The degree to which emotional aspects of stimuli are processed automatically is controversial. Here, we assessed the automatic elicitation of emotion-related brain potentials (ERPs) to positive, negative, and neutral words and facial expressions in an easy and superficial face-word discrimination task, for which the emotional valence was irrelevant. Both emotional words and facial expressions impacted ERPs already between 50 and 100 ms after stimulus onset, possibly reflecting rapid relevance detection. Following this initial processing stage only emotionality in faces but not in words was associated with an early posterior negativity (EPN). Therefore, when emotion is irrelevant in a task which requires superficial stimulus analysis, automatically enhanced sensory encoding of emotional content appears to occur only for evolutionary prepared emotional stimuli, as reflected in larger EPN amplitudes to faces, but not to symbolic word stimuli. 相似文献
