采用重复启动范式探讨语义启动效应减少的机制。结果发现,在SOA为短的167ms条件下,重复/相同和重复/相关的启动效应无差异,且重复/相关启动并未导致语义启动效应的减少;而在SOA为长的1200ms条件下,重复/相同和重复/相关的启动效应差异显著,且重复/相关启动导致了语义启动效应的减少,而重复/相同未导致语义启动效应的减少。在抵消了期望和消退的作用后,在SOA为1200ms条件下所得到的重复/相同和重复/相关启动效应的差异,是由于扩散受到了阻碍而导致的。这一结论支持了激活扩散是有一定条件的观点。 相似文献

Development of behavioural regulation in Do and Don't contexts among behaviourally inhibited Chinese children 下载免费PDF全文

Behavioural inhibition influences the development of behavioural regulation in early childhood. Previous studies have mainly focused on the relationship between inhibition and regulation in the Don't context (e.g., inhibitory control), while few have investigated this relationship in the Do context (e.g., task persistence). This longitudinal study examined the effect of temperamental inhibition on behavioural regulation during both the Do and Don't contexts in 112 Chinese preschoolers. At 3.5 years of age, children's behavioural inhibition was assessed by behavioural observation and parental report, and then at 4.5 years of age, their regulatory behaviours were measured in the following two challenging contexts: Do [locked box (LB)] and Don't [toy inhibition (TI)]. In each task, children were randomly assigned to either a high‐ or a low‐incentive condition designed to vary the value of a given goal. Results suggested that higher inhibition was associated with poorer regulation (lower task persistence) in both conditions of the Do context (LB), whereas in the Don't context (TI) highly inhibited children showed better regulation (less violation behaviours) in the low‐incentive condition than they did in the high‐incentive condition. The results highlight the context characteristics and goal incentive as important factors for behavioural regulation development in inhibited children in China. 相似文献

The eye level and the horizontal midline of the body trunk can serve, respectively, as references for judging the vertical and horizontal egocentric directions. We investigated whether the optic-flow pattern, which is the dynamic motion information generated when one moves in the visual world, can be used by the visual system to determine and calibrate these two references. Using a virtual-reality setup to generate the optic-flow pattern, we showed that judged elevation of the eye level and the azimuth of the horizontal midline of the body trunk are biased toward the positional placement of the focus of expansion (FOE) of the optic-flow pattern. Furthermore, for the vertical reference, prolonged viewing of an optic-flow pattern with lowered FOE not only causes a lowered judged eye level after removal of the optic-flow pattern, but also an overestimation of distance in the dark. This is equivalent to a reduction in the judged angular declination of the object after adaptation, indicating that the optic-flow information also plays a role in calibrating the extraretinal signals used to establish the vertical reference. 相似文献

Computerized classification testing (CCT) commonly chooses items maximizing information at the cut score, which yields the most information for decision-making. However, a corollary problem is that all examinees will be given the same set of items, resulting in high test overlap rate and unbalanced item bank usage, which threatens test security. Moreover, another pivotal issue for CCT is time control. Since both the extremely long response time (RT) and large RT variability across examinees intensify time-induced anxiety, it is crucial to reduce the number of examinees exceeding the time limitation and the differences between examinees' test-taking times. To satisfy these practical needs, this paper proposes the novel idea of stage adaptiveness to tailor the item selection process to the decision-making requirement in each step and generate fresh insight into the existing response time selection method. Results indicate that a balanced item usage as well as short and stable test times across examinees can be achieved via the new methods. 相似文献

Building trust and enhancing consumers' participation are critical for the growth of peer-to-peer sharing economy. This research explores the effect of driver username on passengers' intention to use ride-sharing service and its underlying psychological mechanisms. The results indicate that driver username has a significant impact on passengers' intention to use ride-sharing service, as a driver with a real name elicits greater intention to use ride-sharing service than a driver with a screen name (studies 1, 2, 3a, 3b, and 3c). In addition, the effect of driver username on passengers' intention to use ride-sharing service is serially mediated by social presence and trust (study 2). Importantly, the effect of driver username on passengers' intention to use ride-sharing service is moderated by driver reputation (studies 3a, 3b, and 3c). A high (vs. low) reputation facilitates the impact of driver username on passengers' usage intention. Based upon these findings, theoretical and practical implications are discussed. 相似文献

Over the past decade, research at three different levels of sensorimotor control has revealed a degree of complexity that challenges traditional hypotheses regarding servocontrol of individual muscles: (a) The connectivity of spinal circuits is much more divergent and convergent than expected. (b) The normal and reflex-induced recruitment of individual muscles and compartments of muscles is more finely controlled than was noted previously. (c) The mechanical interactions among linked skeletal segments and their often multiarticular muscles are neither simple nor intuitively obvious. We have developed a mathematical model of the cat hind limb that permits us to examine the influence of individual muscles on posture and gait. We have used linear quadratic control theory to predict the optimal distribution of feedback from a hypothetical set of proprioceptors, given different assumptions about the behavioral goals of the animal. The changes in these predictions that result from changes in the structure and control objectives of the model may provide insights into the functions actually performed by the various circuits in the spinal cord. 相似文献
