Four factors (effectiveness, health risks, cost, and convenience) were orthogonally manipulated in a 3 × 2 × 2 × 2 factorial design to determine their relative importance in influencing attitudes toward and intentions to use male oral contraceptives. The experimental design also permitted a test of the assumption of additivity underlying expectancy-value models of attitude and the assumption of absence of context effects. Results were consistent with expectancy-value models of the relationship between beliefs and attitudes. In addition, it was found that health risks and effedtiveness, in that order, were the most important factors influencing receptivity to male oral contraceptives, with the effects of cost and convenience being mediated by these two factors. Sex differences in attitudes toward male oral contraceptives were also observed. 相似文献

Sentence imagery effects in recall are predicted by both perceptual and semantic elaboration models. The former attributes superior recall of high-imagery sentences to the addition of perceptual network components to an existing semantic network; the latter claims that additions of semantic components are involved. In order to identify the responsible components, free associates were generated to otherwise similar high- and low-imagery sentences in a short-term memory task. In accordance with the perceptual elaboration model, associates differed in rated imagery, but not in number. In a second study, the causal role of perceptual elaboration in recall was investigated by using high- and low-imagery sentence associates as recall cues. Differential effects of cue imagery were found for high-imagery sentences, indicating that perceptual codes are in part responsible for superior high-imagery sentence recall. Evidence is presented that perceptual and semantic network components are involved in a processing trade-off, and the adequacy of present network models to explain it is discussed. 相似文献

The latency of reading a single word is increased by 20 to 40 msec if another object is present in the display. The delay is affected by the spatial organization of the display: a colored frame causes less delay when it surrounds the word than when it is shown on the opposite side of fixation. A small gap in the frame is also more efficiently detected as a secondary task when the frame is around the word than when the two are spatially separate. The advantage of integrated over separate presentation suggests that a “filtering cost” is incurred when two distinct perceptual objects compete for attention. Attention in filtering tasks operates on perceptually distinct objects rather than on nodes in a semantic network. 相似文献

The purpose of the present investigation was to replicate a previous study of diabetic patients on the role of parental modeling in the etiology of illness behavior. A random sample of healthy individuals were assigned to an avoidant model (AM) (i.e. parent reported to have avoided work. chores etc. when ill) or non-avoidant model (NAM) group. Subjects subsequently provided retrospective and current information concerning their illness-behavior experiences. The results indicated that individuals with an AM reported more responsibility avoidance when ill currently and as a child compared to the NAM subjects. Additionally. AM subjects reported receiving more positive reinforcement for current illness compared to NAM subjects. It was concluded that the process by which individuals learn to respond to illness may be similar in healthy and chronically-ill individuals but that positive reinforcement for illness may be more likely to be received by healthy individuals during acute illness than by chronically-ill individuals. The present study provides further preliminary support for the learningtheory model of illness behavior. 相似文献

Tests of the automaticity of reading: dilution of Stroop effects by color-irrelevant stimuli 总被引:5,自引:0,他引:5
D Kahneman D Chajczyk 《Journal of experimental psychology. Human perception and performance》1983,9(4):497-509
A color word shown next to a color bar can facilitate color naming if it is congruent with the correct response; otherwise it will interfere with color naming. The congruence and conflict effects are both diminished (diluted) by the presentation of a color-neutral word elsewhere in the field. A row of X's also produces some dilution. The dilution effect represents attentional interference rather than sensory interaction or response conflict. Because Stroop effects are susceptible to interference, the involuntary reading of color words does not satisfy one of the standard criteria of automaticity. 相似文献
