Pour comparer l'impact de trois techniques d'acquiescement sur l'incitation au comportement charitable, on a demandéà 409 personnes de verser $2 à l'American Cancer Society. Cette requête fut immédiatement présentée dans trois groupes contrôle et précédée dans neuf groupes expérimentaux d'une demande préliminaire correspondant à une procédure d'acquiescement à requête multiple. On a d'abord demandé aux sujets soumis à la technique pied dans la porte de répondre à un questionnaire composé 10, 35 ou 60 items. On sollicitait d'abord $10, 25 ou 50 de la part de ceux confrontés à la situation porte dans la figure; et $0,50, 1 ou 1,50 de la part des sujets ras des pâquerettes. Les résultats montrent que les méthodes $10 et 25 porte dans la figure furent les plus rentables. Les sujets contrôle et ras des pâquerettes donnèrent à peu près la même chose et les conditions pied dans la porte furent les moins productives. On discute, à partir de ces découvertes, de la valeur pratique et des inconvénients virtuels de l'application des techniques d'acquiescement à requête multiple pour stimuler le comportement charitable. 相似文献
When applying self-determination theory to educational settings, evidence suggests that the basic psychological need of relatedness is actually multi-dimensional, which could result in differential influences on intrinsic motivation. Thus, this study proposes a modification to the operationalization of relatedness. The relatedness items from the adapted Basic Satisfaction Needs at Work scale were altered so that items asked students to separately report the amount of connection they feel with their instructors and peers, as opposed to the original items that asked them to more broadly reflect on people in their course. College students (556 female, 321 male) completed a questionnaire assessing their basic psychological needs, including the two new relatedness subscales, motivation, and academic outcomes. Results of exploratory and confirmatory factor analyses revealed that the original relatedness scale should, in fact, be treated as two-dimensional. In addition, of all the basic psychological needs, instructor relatedness was most predictive of student interest/enjoyment in the course and self-reported effort. Conversely, peer relatedness did not significantly predict any outcome variables. Study implications, limitations, and areas for future research are discussed.

L-shaped configuration is a commonly used stimulus configuration in studying horizontal vertical illusion. Here, we report that the horizontal vertical illusion is substantially underestimated when the L-shaped configuration is used for evaluating the illusion. Experiment 1 found that, in a length perception task, the perceived length of a vertical bar was about 10% longer than that of a horizontal bar with the same physical size. Similar amount of HVI was found in a length comparison task, in which the length of a horizontal bar was compared to that of a vertical bar and the two bars were presented separately in space or in time. In contrast, when the length comparison task was conducted with the two bars being arranged in a connected L-shape, the illusion was halved in strength. Experiment 2 and 3 studied what might be the cause of this L-shape induced HVI-underestimation. Two factors were investigated: the connectedness of the two lines, and the 45° absolute orientation or the 45° inner angle information embedded in the upright isosceles L-shape. The results showed that the HVI strength was not much affected when the 45° absolute orientation and the 45° angle information was made useless for the length comparison task. In contrast, the illusion was significantly reduced in strength whenever the two lines were separated as compared to when they were connected. These results suggested that the connectedness of the two lines must underlie the underestimation of the horizontal vertical illusion in the L-shaped configurations. 相似文献
