ResumenEste estudio examina los efectos de la descripción del autor de un delito en su identificación posterior, así como las estrategias utilizadas en la decisión y la confianza en la respuesta. Se preparó un vídeo que representaba el robo de un coche. Sólo la mitad de los sujetos realizó una descripción del autor antes de la tarea de identificación, presentada en vídeo mediante una rueda simultánea con 5 distractores y el autor del delito, indicando a los sujetos que el autor podía estar presente o no. La descripción no afectó ni a la exactitud de la identificación, ni a las estrategias utilizadas por los sujetos. Sin embargo, tanto el nivel de elecciones como la confianza disminuyeron considerablemente con descripción, efectos importantes de ensombrecimiento verbal. Por último, mas sujetos utilizaron espontáneamente procesos de eliminación y comparación que identificación automática, pero en este último caso todas las decisiones fueron correctas, mientras los errores predominaron cuando los sujetos utilizaron estrategias más elaboradas. En conclusión, la descripción previa de una persona, al contrario que la verbalización de una cara, no perjudica a la exactitud de la identificación, aunque es determinante para el nivel de elecciones del autor del delito. 相似文献

为了考察"解释法"、"解释-标记法"两种样例设计方法及其"分步呈现"方式对六年级小学生学习代数运算规则的促进作用,以六年级小学生为被试,以"完全平方和"和"平方差"代数运算样例为学习材料,进行了3项实验研究。结果表明:(1)采用"解释法"设计"完全平方和"和"平方差"的代数运算样例,明显提高了代数运算规则的样例学习效果。(2)在"解释法"设计的样例上添加"运算标记"要运用适当,如果运用不当,特别是"运算标记"过多时,容易增加样例学习的认知负荷,从而降低标记的使用效果。(3)对于运算步骤和"运算标记"过多的样例,采用被试自主控制的"分步呈现"运算步骤的样例学习方式,其学习效果显著优于整体呈现样例的学习效果。 相似文献

Two studies tested whether people interpreted verbal chance terms in a self‐serving manner. Participants read statements describing the likelihood of events in their own future and in the future of a randomly chosen other. They interpreted the chance terms numerically. Chance terms were interpreted as denoting a higher probability when they were used to describe the likelihood of pleasant events in one's own future than when they were used to describe the likelihood of pleasant events in someone else's future (Study 1). Similarly, chance terms were interpreted as denoting a lower probability when they were used to describe the likelihood of unpleasant events in one's own future than when they were used to describe the likelihood of unpleasant events in someone else's future (Studies 1 and 2). These differences occurred primarily when the risk statements were threatening. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

We evaluated the effects of listener training on the emergence of analogical reasoning, as measured via equivalence‐equivalence and explored the role of verbal behavior when solving analogy‐type tasks. We taught 18 college students to select component stimuli from 2 classes, labeled “vek” and “zog,” and evaluated tacts and relational responding in the presence of baseline (AB and BC), symmetry (BA and CB), and transitivity (AC and CA) compounds. In Experiment 1, 5 out of 6 participants passed analogy tests, but none of them engaged in the relational tacts “same” and “different” during tact tests, possibly due to lack of instructional control. A change in instructions during Experiment 2 produced relational tacts in 4 of 6 participants, and 5 participants passed analogy tests. In Experiment 3, we implemented a talk‐aloud procedure to determine if the participants were emitting relational tacts during analogy tests. All 6 participants tacted stimuli relationally and engaged in problem‐solving statements to solve analogy tests. Results from these studies suggest that listener and speaker behavior in the form of relational tacts and other problem‐solving statements influenced the participants' equivalence–equivalence performance. 相似文献

The purpose of the current study was to examine the effects of mand, tact, and native‐to‐foreign (NFI) and foreign‐to‐native (FNI) intraverbal training on the acquisition of a foreign language. We used a multiple‐baseline design across participants with an embedded adapted alternating treatments design to compare the effects of mand training, tact training, NFI training, and FNI training on the acquisition rate of Chinese words in four typically developing adults. We also examined the emergence of untrained foreign language responses for each training condition. Data for 3 out of the 4 participants suggest that mand training was the most efficient training procedure with respect to acquisition rate. The greatest amount of emergent responding was observed for the mand and tact training conditions. 相似文献

Rumination has long been considered a verbal thought process, though emerging evidence suggests that some individuals dwell on maladaptive imagery. This series of studies evaluated imagery and verbal thought during experimentally induced rumination and distraction. In Study 1, imagery and verbal thought during rumination resulted in similar increases in negative affect. Greater imagery during distraction, on the other hand, was associated with greater decreases in negative affect while verbal thought was not related to affect change. Given that greater verbal thought was reported in the rumination condition and greater imagery was reported in the distraction condition, Study 2 evaluated whether the rumination/distraction induction was confounded by concurrent induction of imagery or verbal thought. The rumination prompts induced both rumination and verbal thought and the distraction prompts induced both distraction and imagery. Using a revised induction, Study 3 tested whether imagery and verbal thought during rumination and distraction impacted affective response. Rumination maintained negative affect and distraction relieved negative affect, regardless of the degree to which imagery or verbal thought was experienced. This paper provides evidence that imagery-based rumination is just as impairing as verbally-based rumination and highlights imagery-based distraction as a potentially effective alternative to rumination. 相似文献

The suggestion that neurofunctional reorganization may contribute to preserved language abilities is still emerging in aging studies. Some of these abilities, such as verbal fluency (VF), are not unitary but instead rely on different strategic processes that are differentially changed with age. Younger (n = 13) and older adults (n = 13) carried out an overt self-paced semantic and orthographic VF tasks within mixed fMRI design. Our results suggest that patterns of brain activation sustaining equivalent performances could be underpinned by different strategies facing brain changes during healthy aging. These main findings suggest that temporally mediated semantic clustering and frontally mediated orthographic switching were driven by evolutive neurofunctional resources in high-performing older adults. These age-related activation changes can appear to be compatible with the idea that unique neural patterns expressing distinctive cognitive strategies are necessary to support older adults’ performance on VF tasks. 相似文献
