线索-反应相容性效应和线索有效概率的影响

运用前置线索技术,考察了线索－反应的相容性效应,研究了不同线索与反应的关系和线索有效概率对视觉剌激进行命名反应的时间的影响。结果表明：线索－反应的相容性存在,且符合维度重合理论,支持了相容性是信息加工过程的基本特征;线索客观有效概率影响了线索－反应的相容性效应的强度,线索客观有效概率越高,线索－反应的相容性效应越强。     

Children with developmental coordination disorder (DCD) and their ability to disengage ongoing attentional focus: more on inhibitory function

Children with developmental coordination disorder (DCD), along with their Control counterparts, completed two endogenous, spatial precue tasks. When the precue arrow was informative (.80) with respect to target location, the spatial precue effect results demonstrated that children with DCD take significantly longer than Control individuals to volitionally disengage (inhibit) attention from an endogenously cued location (i.e., a disengagement inhibition deficit). When the precue was uninformative (.25), we found, contrary to a common assumption, that the precue arrow automatically moved attention in the direction of the arrow, and, in addition, that DCD children may also be less able to inhibit the precued-induced urge to move attention (i.e., an initiation inhibition deficit). This type of inhibitory difficulty was also indicated for manual response inclinations produced on catch trials. Overall, DCD children appeared to have an elevated difficulty suppressing the initiation of incorrect, stimulus-provoked movement urges, be they manual or attention in nature.
