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

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

We tested a strategy to encourage cigarette smokers to think more frequently about the negative consequences of smoking, reasoning that increased thought might lead to greater worry and motivation to quit. College students who smoked daily were randomly assigned to one of three conditions in which they wore watches for one week that sounded an alarm randomly four times each day. When alerted, the students read one of eight cards that either had a written statement about studying (control condition), a statement about the negative effects of smoking behaviour (text condition), or a negative smoking statement accompanied by a picture (e.g., a blackened lung; image condition). Measures collected at week's end revealed that the smoking cards had no effects on perceived risk, but they increased worry and reports of intrusive thoughts, and had a small but reliable effect on plans to quit. Correlational data also supported the relationship between worry and motivation to quit, and we discuss the possible benefits of “normal” worrying and strategies for capitalising on the worry–motivation relationship to encourage smokers to abandon cigarettes. 相似文献

Participants are faster at detecting a visual target when it appears at a cued, as compared with an uncued, location. In general, a reversal of this cost-benefit pattern is observed after exogenous cuing when the cue-target interval exceeds approximately 250?ms (inhibition of return [IOR]), and not after endogenous cuing. We suggest that, usually, no IOR is found with endogenous cues because no bottom-up saliency-based orienting processes are claimed. Therefore, we developed an endogenous feature-based split-cue task to allow for endogenous saliency-based orienting. IOR was observed in the saliency-driven endogenous cuing condition, and not in the control condition that prevented saliency-based orienting. These results suggest that usage of saliency-based orienting processes in either endogenous or exogenous orienting warrants the appearance of IOR. 相似文献
