词汇判断中汉语多义词识别的优势效应

运用词汇判断任务,考察了汉语双字词识别中的多义性效应。实验一运用2个真字任意组合构成的假词（如：镜社）作填充材料,发现多义词识别的优势效应仅仅存在于错误率中。实验二运用与源真词（如：冲锋）同音形似的假词（如：冲烽）作填充材料,促使被试更多地在语义水平上做出判断,结果发现很强的多义词识别的优势效应,这种效应主要表现在低频词上。两个实验结果表明,在词汇判断中用不同的假词作填充词会影响被试的词汇判断策略,从而在不同水平上通达词义。最后,用反馈模型对实验结果进行了解释。

Stimuli inevitably generated by behavior that avoids electric shock are inherently reinforcing.

A molecular analysis based on the termination of stimuli that are positively correlated with shock and the production of stimuli that are negatively correlated with shock provides a parsimonious count for both traditional discrete-trial avoidance behavior and the data derived from more recent free-operant procedures. The necessary stimuli are provided by the intrinsic feedback generated by the subject's behavior, in addition to those presented by the experimenter. Moreover, all data compatible with the molar principle of shock-frequency reduction as reinforcement are also compatible with a delay-of-shock gradient, but some data compatible with the delay gradient are not compatible with frequency reduction. The delay gradient corresponds to functions relating magnitude of behavioral effect to the time between conditional and unconditional stimuli, the time between conditioned and primary reinforcers, and the time between responses and positive reinforcers.     

Negative life events, cognitive emotion regulation and emotional problems

A new questionnaire, named the Cognitive Emotion Regulation Questionnaire, has been constructed, measuring nine cognitive coping strategies people tend to use after having experienced negative life events. A test–retest design was used to study the psychometric properties and relationships with measures of depression and anxiety among 547 high school youngsters. Principal component analyses supported the allocation of items to subscales, while alphas of most subscales exceeded 0.80. Cognitive coping strategies were found to play an important role in the relationship between the experience of negative life events and the reporting of symptoms of depression and anxiety. The results suggest that cognitive coping strategies may be a valuable context of prevention and intervention     

The role of response readiness in subliminal visuomotor processes

The present study aims to examine the impact of response readiness on visuomotor processes triggered by subliminal stimuli using a mixed paradigm involving the masked prime paradigm and a foreperiod paradigm. Experiment 1 ensured that response readiness was successfully manipulated in the mixed paradigm. Importantly, Experiment 2 found that the negative compatibility effect (NCE; a behavioral indicator of subliminal visuomotor processes) disappeared and that response time lost its power to modulate the compatibility effect (CE) with reduced response readiness (due to temporal uncertainty). These results of CEs both independent of response latency and across different levels of response latency indicate that response readiness is a prerequisite for obtaining the NCE. The findings suggest that automatic processing of subliminal stimuli is susceptible to top-down control for reducing the interference of irrelevant information, which ensures a high degree of adaptability and flexibility of our cognitive system in interactions with the changing environment.     

The ghost of Christmas future: didn't Scrooge learn to be good? Commentary on Magnuson,McMurray, Tanenhaus,and Aslin (2003)

Magnuson, McMurray, Tanenhaus, and Aslin [Cogn. Sci. 27 (2003) 285] suggest that they have evidence of lexical feedback in speech perception, and that this evidence thus challenges the purely feedforward Merge model [Behav. Brain Sci. 23 (2000) 299]. This evidence is open to an alternative explanation, however, one which preserves the assumption in Merge that there is no lexical–prelexical feedback during on‐line speech processing. This explanation invokes the distinction between perceptual processing that occurs in the short term, as an utterance is heard, and processing that occurs over the longer term, for perceptual learning.
