In the typical induction of the orientation-contingent color aftereffect (CCAE), the stimuli are composed of elements that differ in both color and luminance. Three experiments are reported that show that chromatic contrast between stimulus elements is insufficient for the induction of the orientation-CCAE and that luminance contrast is necessary. These experiments expand on previous research concerned with the role of luminance contrast in the induction of orientation-CCAEs by eliminating alternative explanations. 相似文献

Abstract— A conceptual model based on staffing theory was applied to previously collected survey data from a representative sample of American workers The model links organizational size, workload, work experience variables (felt responsibility and involvement, assessments of work associates), and work outcomes (job satisfaction, work self-esteem, stress symptoms) Path analyses indicated that the model fit data from all waged and salaried workers relatively well When the model was applied to subsamples of new and established employees and of employees from two contrasting occupational groups (professional-technical workers and operative workers), somewhat different patterns emerged The study illustrates the benefits of applying psychological theories across subdisciplines, as well as the limitations of generalizing research findings across different categories of workers We suggest that localized theories and fine-grained analyses of workplace events could help to make research more applicable to work settings 相似文献

Adult subjects in two experiments were presented pairs of stimuli that differed in varying degree on an abstract semantic attribute, and were required to choose the one with the higher value on the given dimension. Subjects in Experiment 1 chose the more pleasant member of a pair of pictures, concrete nouns, or abstract nouns. Those in Experiment 2, presented a pair of pictures or concrete nouns, chose the one whose referent had the higher monetary value. Theoretical interest centered on the effects of semantic distance, stimulus mode, and individual differences in imagery and verbal ability on choice time. In both experiments, response times (1) decreased with increases in semantic distance, (2) were faster for pictures than words (and for concrete than abstract words in Experiment 1), and (3) were faster for high- than for lowimagery participants. The results are completely consistent with a dual-coding (image vs. verbal) interpretation: Pleasantness and value, though conceptually abstract, are attributes of things rather than words, and they are accordingly represented in and processed by a system specialized for dealing with nonverbal information. 相似文献

A simple laboratory computer system based on a Digital Equipment Corporation LSI-11, floppy disk, DRV11 parallel input-output board, and the RT-11 operating system is described. Interface to experimental devices is provided through a lab-built relay driver and relay closure sensing interface. An extensive high-level software package provides an easy-to-use control language (e.g., stimuli can be controlled with a simple “TURN ON” or “TURN OFF” instruction) and easy-to-use FORTRAN subroutines for data exploration (e.g., “IFIND” searches a data file for a particular event). The control software automatically generates, codes, and stores a complete log of every input and output event and its time of occurrence in each of five simultaneously running experiments. This provides the capability to reanalyze data in light of hypotheses not available when the experiment was designed. The FORTRAN subroutine library for data exploration provides a conditional and iterative search facility to sift out events or sets of events from the data file for analysis. Standard FORTRAN statements perform arithmetic operations on the resulting data. 相似文献

A single lever, discrete-trials observing procedure was used with stumptailed monkeys (Macaca arctoides). Lever-presses during a trial produced colored key lights (IS+ and IS?) which signaled whether the trial would end with response-independent food or without food. During the baseline period, both IS+ and IS? were produced on a variable-interval (VI) 15-sec schedule which began operating at the onset of the trial. The two experimental conditions involved a combination of this VI schedule and a DRL schedule. In one of these conditions, only a response that both met the VI requirement and was preceded by at least 6 sec of nonresponding could produce IS? on nonfood trials, while the schedule for IS+ on food trials remained VI 15 sec. In the other experimental condition, the schedules for producing the two stimuli were the reverse. All subjects eventually learned to produce either IS+ or IS? on the combined VI-DRL schedule. These data support an information hypothesis of observing in monkeys and contrast with data from pigeons which support a conditioned reinforcement hypothesis. 相似文献

Process control, the capacity to influence the content of a conflict resolution hearing, has been found repeatedly to affect disputants' judgments of the fairness of conflict resolution procedures, but never has there been an unambiguous test of the effect in nonbinding procedures. It was hypothesized that disputants experiencing nonbinding conflict resolution procedures, as well as those experiencing binding conflict resolution, would judge as more fair procedures high in disputant process control. One hundred nineteen undergraduate males and females were placed in apparent conflict with other suhjects. The procedure used to resolve the conflict was either high or low in disputant process control and was either binding or nonbinding. The outcome of the conflict resolution procedure was either favorable or unfavordblc to the subject. High disputant process control procedures were judged more fair than low disputant process control procedures regardless of whether the decision was binding, confirming the hypothesis. The results support new applications of procedural fairness theory and research and encourage testing of process control-like variables in nonlegal settings. 相似文献

Studies concerned with judgments of contingency between binary variables have often ignored what the variables stand for. The two values of a binary variable can be represented as a prevailing state (nonevent) or as an active state (event). Judgments under the four conditions resulting from the combination of a binary input variable that can be represented as event-nonevent or event-event with an outcome variable that can be represented in the same way were obtained. It is shown in Experiment 1, that judgments of data sets which exhibit the same degree of covariation depend upon how the input and output variables are represented. In Experiment 2 the case where both the input and output variables are represented as event-nonevent is examined. Judgments were higher when the pairing of the input event was with the output event and the input nonevent with the output nonevent that when the pairing was of event with nonevent, suggesting a causal compatibility of event-event pairings and a causal incompatibility of event-nonevent pairings. Experiment 3 demonstrates that judgments of the strength of the relation between binary input and output variables is not based on the appropriate statistical measure, the difference between two conditional probabilities. The overall pattern of judgments in the three experiments is mainly explicable on the basis of two principles: (1) judgments tend to be based on the difference between confirming and disconfirming cases and (2) causal compatibility in the representation of the input and output variables plays a critical role. 相似文献
