编码方式对汉字短时记忆提取的影响

短时记忆提取是认知心理学研究中的重要课题之一。自Sternberg(1 966)提出短时记忆提取作的是序列的从头到尾的完全搜索以来 ,许多研究者对短时记忆提取进行了广泛的研究 ,提出了序列的自动停止的搜索、平行加工、直接存取 ,以及序列搜索和直接存取双重模型等许多不同看法 ,引起了激烈争论。本研究的目的是试图探索编码方式对汉字短时记忆提取的影响。实验运用Sternberg的“探测法” ,以随机排列的汉字作识记组和探测项刺激。实验结果表明 :编码方式对汉字短时记忆提取有很大影响 ,当用声音编码方式提取短时记忆汉字时 ,被试倾向于从头到尾的完全的搜索 ;当用形状编码时 ,被试倾向于作自动停止的搜索。     

Social desirability,perceived stress,and PACT ratings in lung transplant candidates: A preliminary investigation

Some aspect of psychosocial criteria is commonly utilized by most transplant programs in assessing candidates' acceptability for transplantation. However, regardless of the assessment methodology, information obtained in pretransplant assessments may be limited given the evaluative nature of the assessment as well as the sensitive nature of the contents. Indeed, transplant candidates may present themselves in a favorable fashion, minimizing any negative traits or psychological dysfunction which they perceive might prevent transplantation. Unfortunately, there are limited data addressing the extent to which transplant candidates may present themselves in an overly positive light. This investigation surveys the prevalence of social desirability in lung transplant candidates as well as its association with self-reports of perceived stress. Further, the relationship between social desirability and interviewer ratings of transplant candidacy is examined. Subjects included 24 patients in end-stage organ failure being evaluated for lung transplant candidacy. Subjects completed the Perceived Stress Scale and a brief version of the Marlowe-Crowne Social Desirability Scale. Additionally, subjects were interviewer-rated on the Psychosocial Assessment of Candidates for Transplantation. Results indicate social desirability is a prevalent phenomenon in lung transplant candidates, with more than half of the sample scoring at or above the 84th percentile on the social desirability measure. Further, self-reports of perceived stress are moderately and inversely associated with social desirability (r=–.55,p .01). Social desirability was unrelated to interviewer-ratings of transplant candidates acceptability (r=.13,p .56). Future research might include larger samples of subjects, other organ transplant candidates, and more detailed assessments of symptom distress.     

关于听觉条件下中文字词劣效果的研究

对听觉条件下中文字词劣效果的问题进行了实验考察,结果发现：在文章听点作业中,被试对高、低频目标字词语音的正误判断量存在着显著性差别,前者较后者成绩差,表现出字词劣效果的现象;在单字词的听点作业中,未发现被试对高、低频目标字词语音正误判断量方面的显著性差别;无论在文章还是单字词的听点作业中,被试对高、低频目标字词语音的正误判断量均比较低下,表明语音知觉的范畴性特征对字词语音的辩认准确性具有较大影响。     

Conversational skill and locus of perception

The present study attempted to identify behavioral skills associated with global perceptions of communication competence and to determine if the relationship between competence and skills varies as a function of perceptual locus. Fifteen dyadic conversations were videotaped. Each interactant rated self and partner and was rated by four observers who viewed each tape. Results indicated that subjects' perceptions of their partners' skills accounted for 87% of the variance in subjects' ratings of partners' competence and 80% of the variance in subjects'self-perceived confirmation. Observers' ratings of subjects' skills predicted 83% of the variance in observers' ratings of subjects' competence. Observers'ratings of subjects'skills were unrelated to subjects' self-rated competence.     

Validation of the Children's Assertive Behavior Scale

Relationships between sociometric indices and scores of 160 elementary-school children on the Children's Assertive Behavior Scale (CABS) were examined to determine whether this instrument differentiates children of varying levels of social competence. Children who obtained either high or low scores on peer nominations of friendship and admiration were identified and compared on CABS passive, aggressive, and assertive scores. Children who scored high on positive peer nominations responded in a significantly less aggressive manner than children who received low scores on such nominations. These effects were observed for the CABS format that consisted of stimulus situations involving adults but not for the form involving peers. With regard to responses toward peers, a significant interaction between sex and sociometric status emerged. These findings suggest the importance of incorporating subject variables such as race and sex as well as assessments of behavior toward both adults and children in isolating and training components of social skill.The authors wish to express their appreciation to Jean Birbilis, Gail Hammersly, Marieta Knopf, and Donna Wadley for their assistance in data collection and analysis.     

The Heterosocial Assessment Inventory for Women: A psychometric and behavioral evaluation

This paper presents a preliminary psychometric and behavioral evaluation of the Heterosocial Assessment Inventory for Women (HAI-W), a novel self-report instrument that evaluates five dimensions that may influence performance in 12 heterosocial situations: likelihood of initiation, anxiety, skillfulness, expectation of outcome, and influence of attractiveness. Study I obtained acceptable reliability and concurrent validity data and described the factor structure of the HAI-W with female college students. Study II found a significant relationship between the HAI-W factors and global ratings of the role-play performances of high- and low-heterosocially competent female college students as rendered by the male confederate, peer judges, and expert judges. The implications of these findings for the multidimensional assessment and facilitation of heterosocial competence are discussed.This study is part of a dissertation submitted to the Department of Psychology, Georgia State University, under the direction of Michael A. Milan. Portions of these data were presented at the Annual Meeting of the Association for Advancement of Behavior Therapy, Los Angeles, 1982.     

The impact of confederate responsivity on social skills assessment

The current investigation examined the degree to which judges' ratings of skill, anxiety, and attractiveness are influenced by the responsivity of the confederate. High-, medium-, and low-skilled subject-pool groupings, as well as self-referred clinical groups, were exposed to either a moderately or a minimally responsive confederate. Results indicated that subjects were rated as more skillful when interacting with a moderately responsive confederate than when interacting with a minimally responsive confederate. Further, there was a groups × condition interaction for anxiety ratings such that both the high- and the medium-skilled groups appeared more anxious under the minimal condition, whereas the low-skilled and self-referred groups did not. Self-referred subjects received significantly lower attractiveness ratings than did the high- or medium-skilled groups. Implications of these results and future directions for research are discussed.This research is based on a M.S. thesis carried out by the first author under direction of the second author.     

Factor analysis of the social performance survey schedule

There are several studies suggesting that the Social Performance Survey Schedule (SPSS) is a reliable and valid measure of social skill. However, the factorial structure of the SPSS has never been examined. In the present study, SPSSs taken by 652 college students were factor analyzed by the method of principal components and the resulting factors were rotated according to the varimax criterion. Separate factor analyses were conducted for men and women. Seven factors, which accounted for a little over a third of the total variance, were retained for each sex. A large general factor labeled Prosocial Competence emerged for both sexes. Beyond this, the factorial solutions for the two sexes tended to diverge, with males showing a large negative factor (Social Offensiveness) and three smaller negative factors and females showing five relatively small negative factors. Suggestions were made concerning additional factor analytic studies of the SPSS and the ways in which derived factors might be used in research and clinical work.This research was supported by funds from the Rutgers University Research Council.
