元音和复合声识别中噪声分离机制的实验研究

该文用配对比较方法,从夫调谐波的数量对谐波筛的影响（实验一）、失调谐波的位置（实验二）以及谐波相位与其失调幅度之间的相互作用（实验三）等三个方面对失调谐波的分离机制进行探讨。研究结果表明：（1）多个谐波同时失调时其失调效应要比单个谐波强,即谐波失调存在累积效应;（2）谐波次数不同,其失调效应也存在差异,这种差异与谐波和共振峰之间的距离有关,谐波越靠近共振峰,其失调效应越明显,但对由等振幅的谐波系列构成的复合声而言,高次谐波的失调效应比低次谐波弱;（3）谐波相位对其失调效应产生间接影响,这种影响与谐波的起始振幅有关,当相位为π／2和3π／2时,失调效应更加明显。     

伪科学信徒的心理状态分析

伪科学现象的泛滥给社会造成极大危害。而各种伪科学的兴起均有众多信陡做为基础。是什么心理状态使许多人陷入其中,从俯仰危机、文化素质低下、精神病态心理、获益心理、利欲驱动、显示与控制欲等诸方面对伪科学信陡进行心理分析,以利于其迷知返,铲除伪科学现象,净化社会环境。     

谈生理功能的整体调节方式

面对生理学整体水平研究的挑战,应研究生理功能整体调节方式。这一调节方式的基础是神经内分泌免疫网络,它的特征是依照个体特点的分型。讨论其混沌特性,研究方法及医学的影响。     

Empirically identifying factors related to violence risk in corrections.

The authors used structural modeling to predict institutional aggression among male mentally ill offenders using the predictors of anger, antisocial personality style, current violent offense, ethnicity, and impulsivity. Measures included the Barratt Impulsiveness Scale, the Buss-Perry Aggression Questionnaire, the Personality Assessment Inventory, age, ethnicity, current violent offense, victim injury from current offense, and institutional incidents of physical and verbal aggression. The model fit the data, and accounted for 94% and 87% of the variance of physical and verbal aggression, respectively. Results indicated anger, antisocial personality style, and impulsivity are stronger predictors of institutional aggression than are ethnicity and current violent offense; anger was the best predictor. Results suggest dynamic variables such as anger can be targeted for clinical intervention to reduce institutional violence.     

Assessing the winning teams program of interactive satellite-based training

This research assessed an interactive satellite-based training program integrating interactive audiovisual experiences with face-to-face interactions. Key elements were content created by experts, high-quality video segments, satellite-based interaction, off-line interactions among teams of parents and caregivers, workshops, and team building exercises. For pragmatic reasons, it was necessary to develop brief assessment instruments concurrently with training. A large set of survey items were created from draft materials and reduced empirically through piloting to those with the best psychometric properties. To avoid the appearance of traditional testing, knowledge was assessed with Likert items. Surveys measured participant satisfaction, knowledge, attitudes, and the application and articulation of concepts. Participant satisfaction was high. Participants increased positive attitudes and learned appropriate vocabulary. Training was more effective than no training or watching videotapes. The program appears to represent a viable model of training that could successfully be applied to Internet technologies.     

任务难度对基于位置返回抑制时间进程的影响

在返回抑制的实验范式下,采用线索一靶子模式进行了视觉字母觉察实验、实验发现,返回抑制在线索与靶子之间的时间间隔（ＳＯＡ）为７００ｍｓ时出现,且在９００ｍｓ时消退。这与先前许多实验发现的返回抑制在ＳＯＡ为３００ｍｓ左右时出现的结果不一致。作者认为,实验任务的难度是影响返回抑制时间进程的一个重要因素。     

时点,时距和时序信息加工之间相关性研究

本研究分为两个实验,分别采用预期式和回溯式范型,探讨时距、时序和时点三者之间信息加工的相关性,结果发现：同一时间经历,时距估计与时序判断随注意参与程度的增加,由负相关趋势向正相关变化;时距估计与时点离散度可能呈正相关趋势;时序判断与时点离散度随注意参与程度的增加,由负相关趋势向正相关变化。     

遗忘症患者外显与内隐记忆实验研究:语义性启动效应任务

采用ＷＭＳ—ＣＲ和ＭＭＳＥ对临床脑损伤患者进行了认知功能与记忆功能两方面的筛选,获得９名遗忘症患者。然后采用偏好和自由联想两项语义性启动效应任务进行测验,发现遗忘症患者在外显记忆受损情况下,的确存在语义性启动效应,且与正常对照相近。推论语义性启动效应任务与遗忘患者损伤的颞叶或间脑结构无关。同时还讨论了启动效应任务,认为偏好任务采用言语性材料不是理想的方法。     

类比迁移发生机制的研究

本研究包含两个实验,探讨类比迁移发生的机制。实验一主要探索类比迁移中的图式归纳是一种自动加工还是控制加工。实验二主要探索类比迁移中的图式归纳是保留性的还是排除性的。本实验结果表明,类比迁移中的图式归纳主要是控制加工,是一种保留性的归纳。
