We examined the effect of perceptual training on a well-established hemispheric asymmetry in speech processing. Eighteen listeners were trained to use a within-category difference in voice onset time (VOT) to cue talker identity. Successful learners (n=8) showed faster response times for stimuli presented only to the left ear than for those presented only to the right. The development of a left-ear/right-hemisphere advantage for processing a prototypically phonetic cue supports a model of speech perception in which lateralization is driven by functional demands (talker identification vs. phonetic categorization) rather than by acoustic stimulus properties alone. 相似文献

Few studies have explored the effects of fixed‐time (FT) reinforcement on escape‐maintained behavior of students in a classroom setting. We measured the effects of an FT schedule on the disruptive and appropriate academic behaviors of 2 junior high students in a public school setting. Results demonstrated that FT escape from tasks resulted in a substantial decrease in disruptive behavior and an increase in time engaged in tasks for both participants. 相似文献

The effectiveness of a fixed‐ratio (FR) escalation procedure, developed by Pinkston and Branch (2004) and based on interresponse times (IRTs), was assessed during lever‐press acquisition. Forty‐nine experimentally naïve adult male Long Evans rats were deprived of food for 24 hr prior to an extended acquisition session. Before the start of the session, three food pellets were placed in the magazine. Otherwise, no magazine training, shaping, nor autoshaping procedure was employed. The first 20 presses each resulted in the delivery of a 45‐mg food pellet. Then, the FR increased (2, 4, 8, 11, 16, 20, 25, 30) when each IRT in the ratio was less than 2 s during three consecutive ratios. Sessions lasted 13 hr or until 500 pellets were earned. On average, rats reached a terminal ratio of 11 (mean) or 16 (median) during the first session. Seven rats reached the maximum value of FR 30 and only one rat did not acquire the response. In most rats, a break‐and‐run pattern of responding characteristic of FR schedules began to develop in this acquisition session. Subsequently, the ratio‐escalation procedure continued during daily 2‐hr sessions. In these sessions, the starting ratio requirement was set at the terminal ratio reached in the previous session. Using this procedure, over half (26) of the rats reached the FR 30 requirement by the fourth session. These data demonstrate that a ratio‐escalation procedure based on IRTs provides a time‐efficient way of establishing ratio responding. 相似文献

Thing, Value, Time, and Freedom: A Consideration of Some Key Concepts in Marx’s Philosophical System
Wujin Yu 《Frontiers of Philosophy in China》2006,1(1):114-123
Criticizing the misunderstanding and wrong explanation of Marx’s philosophical system made by recent Chinese textbooks on
Marxist philosophy, the author argues that Marx’s philosophy has practical, economical-philosophical, and ontological dimensions
and stresses on reconstructing Marx’s philosophical system through synthesizing the above three dimensions. This paper intends
to set up a new outline of Marx’s philosophical system, in terms of the following four concepts—thing, value, time, and freedom.

时间和人格都是心理学领域极为重要的研究内容。时间无处不在,它不仅是基本心理过程的存在方式,而且也是人格特征的存在方式。时间与人格心理的研究是现代心理学研究的重要领域之一。《时间与人格心理学探索》一书,向我们详尽地展现了时间和人格心理学的研究成果。综观全书,主要凸显四个方面特点:一、研究取向上强调中国化;二、研究过程上体现长期性;三、研究方法上注重多样性;四、研究成果上凸显创新性。 相似文献

中学生好胜心培养的实验研究 总被引:2,自引:0,他引:2
以积极的归因训练、表扬与奖励和适当的竞赛等手段对中学生的好胜心进行培养,通过一个学期三个阶段的培养,结果发现,实验班学生的好胜心水平增量显著高于对照班学生,实验班学生的学习成绩增量也显著高于对照班学生,好胜心水平与学习成绩存在着显著的正相关。研究表明,积极的归因训练、表扬与奖励、适当的竞赛是培养中学生好胜心的有效措施。 相似文献

The author offers a critique on current counseling psychology research from her perspective as a US counseling psychology researcher and editor. She notes that unless something happens to change the trajectory, future US counseling psychology research will be open to the same criticisms. She summarizes counseling psychology values and argues that counseling psychology research reflects those values. She then identifies five ways that counseling psychology could be different in the future by: building theory-based research, embracing diversity of populations, research questions and methodologies, informing (and being informed) by other psychological disciplines, and informing policy and practice. 相似文献

采用攻击性问卷、关系攻击行为量表、结果预期量表、移情量表和自我控制能力问卷对720名中学生进行调查,考察了结果预期与青少年攻击性行为的关系,以及自我控制在其中的中介作用和移情在其中的调节作用。结果发现:(1)结果预期与青少年的攻击性行为(外部攻击和关系攻击)存在显著负相关;(2)自我控制在结果预期与青少年攻击性行为之间起着完全中介作用;(3)在结果预期对青少年外部攻击行为的预测中,移情发挥了调节作用。在高移情个体中,结果预期并不预测外部攻击行为,而在低移情个体中,结果预期显著地反向预测外部攻击行为;(4)自我控制在结果预期与青少年外部攻击行为之间的中介作用受到移情的调节,高水平的移情能力可以有效地缓解青少年因低自我控制而导致的高攻击性。 相似文献

急性心肌梗死(AMI)患者的治疗关键在于早期诊断和及时开通闭塞的冠状动脉,患者在发病后能否及早到院接受再灌注治疗,对患者的治疗效果和预后有重要影响.院前延误时间(PDT)即为从患者出现症状至到达医院接受治疗的时间.AMI患者就医大多是延迟的,主要原因是患者不能决定自己的症状是否需要治疗,也就是患者决定就医时间延长.本研究目的是分析造成急性心肌梗死患者院前延误的相关影响因素,为患者赢得最佳治疗时间提供理论依据. 相似文献
