语音意识、语素意识和快速命名在儿童言语发展中的作用

以130名幼儿园小、中、大班儿童为研究对象,通过分层回归,系统比较了语音意识、语素意识和快速命名三种认知技能在学前儿童口语词汇、汉字识别和阅读理解等言语能力发展中的作用和相对重要性,结果发现:(1)学前儿童的各项能力随着年龄的增加而显著提高;(2)除了年龄因素之外,语音意识和语素意识是解释口语词汇的重要变量;(3)在控制了年龄和口语词汇量之后,语音意识、语素意识和快速命名能力都分别对汉字识别成绩具有独立的预测作用;(4)在控制了年龄、口语词汇量、汉字识别和其他两种认知技能之后,只有语素意识仍然能够独立预测阅读理解成绩,表明语素意识对于汉语阅读能力的发展具有独特的作用.     

Video-based assessment of interpersonal problem solving skills in patients with schizophrenia, their siblings and non-psychiatric controls

The aim of this study was to analyze social functioning in patients with schizophrenia and their biological relatives with a Swedish version of the video-based vignette test Assessment of Interpersonal Problem Solving Skills (AIPSS). In a new video production with simulated "real life" situations we tested the ability to receive, process and send social information in 25 individuals with a DSM-IV diagnosis of schizophrenia, 20 siblings to patients with schizophrenia and 25 randomly selected non-psychiatric controls. The test proved to have good validity and interrater reliability. After controlling for positive or negative symptoms, patients had poor performance especially in acting out solutions leading to effective problem solving. Siblings generally did not differ from controls, but showed some deficiencies in non-verbal language. To conclude, AIPSS is appropriate for use in a Swedish-speaking context and might be useful in research on vulnerability indicators and in assessment of treatment interventions.     

Cracking the Code of Genocide: The Moral Psychology of Rescuers,Bystanders, and Nazis during the Holocaust

What turns neighbors into genocidalists? Why do some stand by, while others risk their lives to help? A narrative analysis of interviews with rescuers, bystanders, and Nazi supporters during World War II focuses attention on self‐image, worldview, and cognitive categorization as critical influences. Rescuers, bystanders, and Nazis demonstrated dramatically different self concepts, yet identity constrained choice for all groups. A critical aspect of identity is relational: the sense of self in relation to others. Worldview, canonical expectations, and idealized cognitive models are critical determinants, with the ethical importance of values emanating not from particular values but from the integration of these values into the speaker's sense of self. Finally, cognitive categorization carries strong ethical overtones. The dehumanization that spurs perpetrators and the sense of moral salience that drives rescuers work through the cognitive classification of “the other.”     

Using a System of Least Prompts Procedure to Teach Telephone Skills to Elementary Students with Cognitive Disabilities

Using the telephone to contact others can be an important skill in maintaining friendships with peers. This investigation used a system of least prompts (SLP) procedures to teach two telephone skills to 3 elementary students with cognitive disabilities: (a) placing phone calls and (b) leaving recorded voicemail messages. The SLP procedure was effective in teaching both skills to all 3 students. Results for maintenance and generalization, however, were mixed. This investigation was completed to partially satisfy the thesis requirement for a Master’s degree at the University of Kentucky.     

Skills Evaluator: a multicriteria decision support system for the evaluation of qualifications and skills in Information and Communication Technologies

Employees need to acquire new qualifications throughout their lives in order to deal with the multiple changes in the labour market. This knowledge and competences (formally or non-formally acquired) must be identified and evaluated. For that reason, an integrated approach to the evaluation of Information and Communication Technology knowledge and skills is proposed. The multicriteria method that has been developed refers to professionals who wish to be accredited in a particular specialization through the evaluation of their professional experience, studies and vocational training. The aim of this paper is to present the multicriteria decision support system, Skills Evaluator, which brings into effect the aforementioned method. Copyright © 2007 John Wiley & Sons, Ltd.     

MODIFICATION OF PERSEVERATIVE RESPONDING THAT INCREASED EARNINGS BUT IMPEDED SKILL ACQUISITION IN A JOB‐SKILLS TRAINING PROGRAM

Adults in a therapeutic workplace working on a computerized keyboarding training program earned vouchers for typing correct characters. Typing technique was evaluated on review steps. Participants could pass the review and earn a bonus, or skip the review and proceed with no bonus. Alternatively, participants could continue practicing on the same step. Participants persistently repeated the same step, which halted progress through the program but allowed them to increase their rate of responding and, as a result, their earnings. Blocking the initiation of practice on review steps and removing payment for practice initiated after prompts (extinction) both produced rapid progress through the program. These results underscore the importance of careful arrangement of the contingencies in adult education programs.     

THE EFFECTS OF BEHAVIORAL SKILLS TRAINING ON CAREGIVER IMPLEMENTATION OF GUIDED COMPLIANCE

The effectiveness of a behavioral skills training package that consisted of modeling, rehearsal, and feedback was evaluated to increase correct implementation of guided compliance by caregivers of 3 children who exhibited noncompliance. Results showed that the training package improved performance of guided compliance. Generalization probes indicated that the skills learned were exhibited in different settings 3 to 6 weeks after training ended.     

The mediating role of positive relations with others in associations between depressive symptoms, social skills, and perceived stress

This study was designed to examine the role of positive relations with others as a mediator of the association between poor social skills and depression and between depression and increased perceptions of stress. To test these two models, data were collected from 179 young adults assessed three times over the course of 4 months. Sobel’s product of coefficients test and lower-level mediation modeling were used to evaluate these predictions. The results showed that positive relations with others completely mediated the negative association between social skills and depression. Social skills also moderated the positive association between depression and perceptions of stress. These findings illustrate how positive relations with others function to promote psychological well-being.     

The influence of perceptual and semantic categorization on inhibitory processing as measured by the N2–P3 response

In daily activities, humans must attend and respond to a range of important items and inhibit and not respond to unimportant distractions. Our current understanding of these processes is largely based on perceptually simple stimuli. This study investigates the interaction of conceptual-semantic categorization and inhibitory processing using Event Related Potentials (ERPs). Participants completed three Go–NoGo tasks that increased systematically in the degree of conceptual-semantic information necessary to respond correctly (from single items to categories of objects and animals). Findings indicate that the N2 response reflects inhibitory processing but does not change significantly with task difficulty. The P3 NoGo amplitude, on the other hand, is attenuated by task difficulty. Further, the latency of the peak of the P3 NoGo response elicited by the most difficult task is significantly later than are the peaks detected during performance of the other two tasks. Thus, the level of complexity of conceptual-semantic representations influences inhibitory processing in a systematic way. This inhibition paradigm may be a key for investigating inhibitory dysfunction in patient populations.
