Low-frequency irregular words are named more slowly and are more error prone than low-frequency regular words (the regularity
effect). Rastle and Coltheart (1999) reported that this irregularity cost is modulated by the serial position of the irregular
grapheme-phoneme correspondence, such that words with early irregularities exhibit a larger cost than words with late ones.
They argued that these data implicate rule-based serial processing, and they also reported a successful simulation with a
model that has a rule-based serial component—the DRC model of reading aloud (Coltheart, Rastle, Perry, Langdon, & Ziegler,
2001). However, Zorzi (2000) also simulated these data with a model that operates solely in parallel. Furthermore, Kwantes
and Mewhort (1999) simulated these data with a serial processing model that has no rules for converting orthography to phonology.
The human data reported by Rastle and Coltheart therefore neither require a serial processing account, nor successfully discriminate
among a number of computational models of reading aloud. New data are presented wherein an interaction between the effects
of regularity and serial position of irregularity is again reported for human readers. The DRC model simulated this interaction;
no other implemented computational model does so. The present results are thus consistent with rule-based serial processing
in reading aloud. 相似文献

Cognitive behaviour therapy is effective for obsessive-compulsive disorder and for obsessive-compulsive spectrum disorders such as trichotillomania. Unfortunately, many people with these disorders, especially those living in rural areas, have limited access to treatment. Telephone-administered cognitive behaviour therapy may help address this problem. In a recent study of telephone treatment for obsessive-compulsive disorder, we found that such treatment was often effective (42% in remission at post-treatment, and 47% in remission at 12-week follow-up). This article presents 2 case reports of the same treatment, applied to obsessive-compulsive spectrum disorders (trichotillomania and compulsive skin picking). Treatment was associated with symptom reduction for both participants, although one subsequently relapsed. Possible reasons for relapse are discussed. The findings encourage further studies to identify the characteristics of people most likely to benefit from telephone treatment for spectrum disorders. 相似文献

The present investigation analyzes the characteristics of two tasks that have been considered as a measure of visuospatial abilities: The Knox Cube Imitation Test and the Corsi Blocks Test. The former was originally devised by Knox (1913) to diagnose mental retardation in potential immigrants to the United States, while the latter has been specifically designed to be used in neuropsychological practice by Corsi (1972). Although both tasks have been widely used in the past, there is little empirical research investigating the characteristics of these tasks from a theoretical point of view. In order to do so, we carried out two parallel experiments in which both tasks were presented in a baseline condition as well as in association with three different concurrent tasks (i.e., articulatory suppression, spatial tapping, and random generation) supposed to tap the various components of working memory. Results showed that neither of the tasks can be considered as a pure measure of visuospatial processing and that, at the same time, it is necessary to reconsider the architecture of working memory in order to suggest a more integrated functioning of the system. 相似文献

The present study examined the impact of parental divorce during adolescence, interparental conflict, and intimacy with parents on young adult adjustment. One hundred sixty-seven undergraduate students (146 females, 21 males) completed a questionnaire regarding their psychosocial adjustment, their present relationships with their parents, the level of interparental conflict experienced during adolescence, and the marital status of their parents during adolescence. High levels of interparental conflict were found to be negatively associated with adjustment and current intimacy with parents. A poor relationship with both parents was negatively associated with several domains of psychosocial adjustment, while high intimacy with at least one parent was positively associated with adjustment. Intimacy with mother and with father were found to be the most important predictors of psychosocial adjustment. This investigation highlights the importance of maintaining a good parent-young adult relationship, particularly in divorced families. The findings indicate that future research should examine multiple family variables when assessing the impact of parental divorce or conflict on young adult adjustment. 相似文献

According to the contextual change theory of memory loss, spontaneous forgetting reflects a retrieval impairment due to subtle and unprogrammed shifts in environmental cues over a retention interval. However, Riccio, Richardson, and Ebner (1984) noted an apparent paradox in this model; specifically, laboratory studies inducing explicit shifts in contextual cues found less disruption of performance as retention intervals increased. Bouton, Nelson, and Rosas (1999) critiqued several of the claims made by Riccio et al. and concluded that the contextual cue theory is still a valid account of spontaneous forgetting. In this comment, the authors address the 3 major criticisms offered by Bouton et al., point out an inconsistency in their argument, and conclude that the original paradox still poses problems for the contextual change theory of forgetting. 相似文献

Three experiments investigated the perception of collisions involving bouncing balls by 7- and 10-month-old infants and adults. In previous research, 10-month-old infants perceived the causality of launching collisions (events in which one object moves along a smooth horizontal trajectory toward a second object, apparently launching it into motion) in relatively simple event contexts. In more complex event contexts, infants failed to discriminate among the events or respond to changes in individual features. Experiments 1 and 2 of the present investigation revealed that 7- and 10-month-old infants attended to spatial and temporal contiguity, but not causality, in collisions involving the movement of bouncing balls. In Experiment 3, both spatiotemporal contiguity and general knowledge about movement trajectories influenced adults’ judgments of causality for these collisions. The present results add to a growing understanding of infants’ event perception as constructive and a function, in part, of the complexity of the event context. 相似文献

This paper examines in detail the multitude of ways used by Jesus Movement organizations to raise money to fund their many activities. The research was provoked by sharp differences between fund‐raising methods used by the two largest and well known JM organizations—the Children of God (now called The Family) and Christ Communal Organization (a pseudonym for a group called Shiloh). The COG mainly relied on various forms of public solicitation, while Shiloh depended on working for others and themselves in an effort to become self‐supporting. Seven other JM groups were examined to find out what patterns of support were most prevalent, and to examine possible relationships between sustenance activities and theological developments within the groups. A large number of experimental approaches were taken by JM groups trying to sustain themselves during their sometimes tumultuous histories, leading to a number of general conclusions. 相似文献

A central issue for researchers of human spatial knowledge, whether focused on perceptually guided action or cognitive-map acquisition, is knowledge of egocentric directions, directions from the body to objects and places. Several methods exist for measuring this knowledge. We compared two particularly important methods, manual pointing with a dial and whole-body rotation (body heading), under various conditions of sensory or memory access to targets. In two experiments, blindfolded body rotation resulted in the greatest variability of performance (variable error), while the manual dial resulted in greater consistent bias (constant error). The variability of performance with body rotation was no greater than that of the dial when subjects' memory loads for directions to targets was reduced by allowing them to peek at targets in between trials, point to concurrent auditory targets, or point with their eyes open. In both experiments, errors with the manual dial were greater for directions to targets that were further from the closest orthogonal axis (ahead, behind, right, left), while errors with body rotation with restricted perceptual access were greater for directions to targets that were further from an axis straight ahead of subjects. This suggests that the two methods will produce evidence of different organizational frameworks for egocentric spatial knowledge. Implications for the structures and processes that underlie egocentric spatial knowledge, and are involved in estimating directions, are discussed, as is the value of decomposing absolute errors into variable and constant errors. 相似文献
