Rosner and Kochanski (2009) noticed an inconsistency in the mathematical statement of the Law of Categorical Judgment and derived "the valid equation, the Law of Categorical Judgment (Corrected)" (p. 125). The purpose of this comment is to point out that the law can be corrected in many different ways, leading to substantially different equations. The different versions have different consequences for the predicted distributions of the responses and, hence, for fitting real data. Some of these consequences are unexpected and sometimes undesirable. Researchers should be aware of the different possibilities as they may lead to pronouncedly different accounts of given data. 相似文献

In this study, we used event-related potentials (ERPs) to evaluate the contribution of surface color and color knowledge information in object identification. We constructed two color-object verification tasks - a surface and a knowledge verification task - using high color diagnostic objects; both typical and atypical color versions of the same object were presented. Continuous electroencephalogram was recorded from 26 subjects. A cluster randomization procedure was used to explore the differences between typical and atypical color objects in each task. In the color knowledge task, we found two significant clusters that were consistent with the N350 and late positive complex (LPC) effects. Atypical color objects elicited more negative ERPs compared to typical color objects. The color effect found in the N350 time window suggests that surface color is an important cue that facilitates the selection of a stored object representation from long-term memory. Moreover, the observed LPC effect suggests that surface color activates associated semantic knowledge about the object, including color knowledge representations. We did not find any significant differences between typical and atypical color objects in the surface color verification task, which indicates that there is little contribution of color knowledge to resolve the surface color verification. Our main results suggest that surface color is an important visual cue that triggers color knowledge, thereby facilitating object identification. 相似文献

Mental simulations of future experiences are often concerned with emotionally arousing events. Although it is widely believed that mental simulations enhance future behavior, virtually nothing is known about how memory for these simulations changes over time or whether simulations of emotional experiences are especially well remembered. We used a novel paradigm that combined recently developed methods for generating simulations of future events and well-established procedures for testing memory to examine the retention of positive, negative, and neutral simulations over delays of 10 min and 1 day. We found that at the longer delay, details associated with negative simulations were more difficult to remember than details associated with positive or neutral simulations. We suggest that these effects reflect the influence of the fading-affect bias, whereby negative reactions fade more quickly than positive reactions, and that this influence results in a tendency to remember a rosy simulated future. We discuss implications of our findings for individuals with affective disorders, such as depression and anxiety. 相似文献

A spatial compatibility effect (SCE) is typically observed in forced two-choice tasks in which a spatially defined response (e.g., pressing a left vs. a right key) has to be executed to a nonspatial feature of a stimulus (e.g., discriminating red from green) that is additionally connoted by a spatial feature (e.g., the stimulus points to the left or the right). Responses are faster and more accurate when the response side and the spatial stimulus feature are compatible than when they are incompatible. Previous research has demonstrated that SCEs are diminished when stimuli from only one response category are responded to in individual go/no-go tasks, whereas SCEs reemerge when two participants work jointly on two complementary, individual go/no-go tasks in a joint go/no-go task setting. This social Simon effect has been considered evidence for shared task representations. We show that SCEs emerge in individual go/no-go tasks when the spatial dimension is made more salient, whereas SCEs are eliminated in joint go/no-go tasks when the spatial dimension is made less salient. These findings are consistent with an account of social Simon effects in terms of spatial response coding, whereas they are inconsistent with an account of shared task representations. The relevance of social factors for spatial response coding is discussed. 相似文献

RESUMENLos autores comienzan planteando que las opiniones vertidas en algunas revisiones acerca del constructo placebo son respuestas a la evolución actual hacia el empleo de conceptualizaciones más cognitivas en la psicoterapia. Seguidamente ofrecen un breve repaso histórico de esta noción, para centrarse en sus aspectos denotativos y connotativos. Respecto a los primeros, revisan las dos metáforas dominantes que pueden encontrarse en la literatura: (a) los placebos como ingredientes inertes en vez de activos y (b) como agentes no específicos en vez de específicos. En relación con los aspectos connotativos, examinan las cuatro fuentes de donde proceden y afirman que distinguiendo entre los verdaderos efectos placebo y los artefactos de medida las connotaciones negativas de este constructo son inmerecidas. Seguidamente abordan su utilidad en la evaluación de la eficacia de la psicoterapia y responden a la cuestión de si las terapias actuales son más eficaces que el tratamiento inespecífico. Este trabajo concluye que como el placebo ha de jugar un papel crucial en la evaluación científica de la psicoterapia, rechazarlo prematuramente constituiría una regresión conceptual y metodológica. 相似文献

Surprise has been described in various contexts as a neutral, a positive, or a negative emotion. Six experiments are reported in which surprise ratings of unexpected positive and negative outcomes, with identical prior probabilities, were compared. For unexpected occurrences of events that are beyond the control of the protagonist, successes were consistently perceived as more surprising than failures. For unexpected action controlled outcomes for which the protagonist was partly responsible, failures were rated as more surprising than successes. The findings are interpreted as being due to an implicit contrast between out-of-control situations and success, in the first case, and between goal-directed efforts and failure, in the second. 相似文献

A number of single- and dual-process theories provide competing explanations as to how reasoners evaluate conditional arguments. Some of these theories are typically linked to different instructions—namely deductive and inductive instructions. To assess whether responses under both instructions can be explained by a single process, or if they reflect two modes of conditional reasoning, we re-analysed four experiments that used both deductive and inductive instructions for conditional inference tasks. Our re-analysis provided evidence consistent with a single process. In two new experiments we established a double dissociation of deductive and inductive instructions when validity and plausibility of conditional problems were pitted against each other. This indicates that at least two processes contribute to conditional reasoning. We conclude that single-process theories of conditional reasoning cannot explain the observed results. Theories that postulate at least two processes are needed to account for our findings. 相似文献

From personal experiences of working with coaches toward the modification of behaviors and psychological constructs that include motivation, enjoyment, and self-confidence, this commentary highlights how the integration of single case designs can enhance the services of sport psychology practitioners. Interventions within golf, soccer, and tennis are outlined, targeting factors pertinent to the coaches, their players or team members, and the development of relationships with parents. Single case designs are posited as enabling the implementation of personal, evidence-based interventions that yield perceptible differences in cognitive, affective, and behavioral responses within athletic populations; factors that enhance and underpin the practitioner-coach relationship. 相似文献
