The role of ‘action-effects’ and agency in toddlers’ imitation

We report an experiment on imitation by children between 14 and 26 months in which the presence or absence of an outcome of the procedure to be imitated was varied against whether the procedure was one performed by the experimenter or by a descending arrow. The presence of an outcome did not affect performance positively when the procedure was performed by the experimenter, but it did when it was performed by the descending arrow. When there was an outcome, performance on the experimenter-perform and the arrow-perform conditions did not differ. We argue that this result puts pressure on theories like ‘the theory of common coding’ (W. Prinz) which view the presence of an outcome as being crucial to imitation.     

Promoting Generalization of Oral Reading Fluency: Providing Drill versus Practice Opportunities

Extensive evidence exists demonstrating the benefits of repeated readings (RR) interventions at increasing students’ fluency on intervention passages. Few studies however have examined the extent to which repeatedly reading one passage improves students’ reading fluency on similar passages. Using an alternating treatment design, we examined the extent to which two interventions resulted in improvements in students’ fluency on generalization passages. While both interventions incorporated RR, one intervention involved students reading one passage four times and the other involved students reading two similar passages each twice. Intervention effects were evaluated by having students read a generalization passage prior to and following intervention implementation. Results indicate that both interventions were effective in increasing students reading fluency on generalization passages. For 3 participants the RR intervention produced greater gains in fluency on the generalization passages, while data for the remaining 3 participants are inconclusive. Implications of these findings for practice and for better understanding application of the instructional hierarchy to the development of reading interventions are discussed.

Dissimilarity cumulation theory and subjective metrics

We present a new mathematical notion, dissimilarity function, and based on it, a radical extension of Fechnerian Scaling, a theory dealing with the computation of subjective distances from pairwise discrimination probabilities. The new theory is applicable to all possible stimulus spaces subject to the following two assumptions: (A) that discrimination probabilities satisfy the Regular Minimality law and (B) that the canonical psychometric increments of the first and second kind are dissimilarity functions. A dissimilarity function Dab for pairs of stimuli in a canonical representation is defined by the following properties: (1) a≠b?Dab>0; (2) Daa=0; (3) If and , then ; and (4) for any sequence {a_nX_nb_n}_n∈N, where X_n is a chain of stimuli, Da_nX_nb_n→0?Da_nb_n→0. The expression DaXb refers to the dissimilarity value cumulated along successive links of the chain aXb. The subjective (Fechnerian) distance between a and b is defined as the infimum of DaXb+DbYa across all possible chains X and Y inserted between a and b.     

泛文化的自尊——基于中国大学生的研究证据

过去一直认为,自尊是人类普遍的需要,是泛文化的。但是,过去十多年来,这一观点受到严重挑战。其主要理由是许多跨文化的研究显示集体主义文化下个体的自尊显著低于西方,少有自我促进的迹象。但是,几乎所有这样的证据都是来自自陈式测量。由于自陈式测量难以避免自我展现（Self-presentation）或社会期许（Social Desirability）的影响,并且严重依赖于个体的自我报告,本研究采用新的能够防止社会期许的影响并能触及无意识的内隐测量——阈下评价性启动（Subliminal Evaluative Priming）程序,对中国大学生的自尊进行了研究。结果发现中国大学生对自我持有显著的积极、肯定的评价,中国人存在内隐自尊。这表明,集体主义文化下的个体的自尊需要是存在的,只是以内隐的方式表现或在自我展现的影响最小化后表现出来。这一发现和自尊的泛文化论是一致的     

Accuracy,Consensus, In-Group Bias,and Cultural Frame Shifting in the Context of National Character Stereotypes

We examined Finns’ and bilingual Swedish-Finns’ stereotypes regarding personality differences between Finns and Swedish-Finns and compared them with their respective self-ratings. Stereotype ratings by both groups converged on depicting Swedish-Finns as having a more desirable personality. In-group bias also influenced stereotypes. Contrary to predictions based on the Stereotype Content Model, out-group stereotypes were not compensatory. Consistent with the kernel of truth hypothesis of national stereotypes, Swedish-Finns’ aggregate self-ratings resembled their stereotype of personality differences between the two groups, and their personality self-ratings were more desirable than Finns’ self-ratings. Tentatively suggesting the occurrence of cultural frame shifting, the resemblance between Swedish-Finns’ self-ratings and their stereotype of Swedish-Finns was, although only marginally statistically significantly, somewhat stronger when the self-ratings were provided in Swedish.     

Accounting for the evaluative factor in self-ratings provides a more accurate estimate of the relationship between personality traits and well-being

Social desirability may cause spurious relations in self-rating measures. The present study sought to disentangle socially desirable responding and content in the relation between measures of personality traits and well-being. Social desirability was operationalized as the evaluative factor (the tendency to react to evaluative content in questionnaire items). We collected self- and peer-ratings of personality and self-ratings of well-being from 219 participants. The evaluative factor in personality self-ratings significantly predicted well-being and explained more variance than all Big Five traits combined. The evaluative factor in personality peer-ratings had no unique relation to well-being. These findings suggest that previous estimates of the relationship between personality traits and well-being have generally been exaggerated. Different methods of accounting for social desirability are discussed.     

Not too little, but not too much: The perceived desirability of responses to personality items

Paradigms typically employed to investigate socially desirable responding in personality assessment implicitly assume linear relationships exist between trait level and desirability but recent research has called this assumption into question. In this study, participants rated the desirability of a hypothetical applicant to one of four jobs on the basis of which five-point Likert-type scale option he/she selected when responding to personality items. Results generally indicated that the most extreme option, on the desirable side of the response scale, was rated as most desirable, but perceived desirability asymptotes with the penultimate option. The middle (neutral) option, however, was consistently regarded as being much less desirable. The occupational context also significantly moderated the patterns of desirability ratings for many items.     

Social desirability, personality questionnaires, and the “better than average” effect

It is well established that respondents are much more likely to rate themselves highly on personality questionnaire items with high social desirability (SD) than on items with low SD. However, conflicting explanations have been offered for this phenomenon. In the present study, 286 participants were randomly assigned to four groups that rated 119 items from two well-known personality questionnaires. One group of participants rated themselves, a second group rated their family and friends, a third rated “people in general,” and a fourth rated the items’ SD. It was found that mean SD ratings of personality items were highly correlated with mean self-ratings and with mean ratings of family and friends for the same items (all rs > .800), but not with mean ratings of “people in general.” In other words, participants strongly tended to rate themselves, their family, and their friends as high on socially desirable qualities, but this tendency did not extend to ratings of people in general. These results support the conclusion that respondents’ personality ratings of themselves, their family and friends, but not of people in general, are influenced by the form of self-serving bias known as the “better than average effect.”
