The Norwegian discussion of the training analyst system and the pro et contra arguments are shortly presented. When this note is written, the Board is contemplating to propose a revision of the by-laws, making it somewhat easier to fulfil the criteria for being approved as training analyst. 相似文献

A multi‐group factor model is suitable for data originating from different strata. However, it often requires a relatively large sample size to avoid numerical issues such as non‐convergence and non‐positive definite covariance matrices. An alternative is to pool data from different groups in which a single‐group factor model is fitted to the pooled data using maximum likelihood. In this paper, properties of pseudo‐maximum likelihood (PML) estimators for pooled data are studied. The pooled data are assumed to be normally distributed from a single group. The resulting asymptotic efficiency of the PML estimators of factor loadings is compared with that of the multi‐group maximum likelihood estimators. The effect of pooling is investigated through a two‐group factor model. The variances of factor loadings for the pooled data are underestimated under the normal theory when error variances in the smaller group are larger. Underestimation is due to dependence between the pooled factors and pooled error terms. Small‐sample properties of the PML estimators are also investigated using a Monte Carlo study. 相似文献

The present study explored whether the phonological bias favoring consonants found in French‐learning infants and children when learning new words (Havy & Nazzi, 2009; Nazzi, 2005) is language‐general, as proposed by Nespor, Peña and Mehler (2003), or varies across languages, perhaps as a function of the phonological or lexical properties of the language in acquisition. To do so, we used the interactive word‐learning task set up by Havy and Nazzi (2009), teaching Danish‐learning 20‐month‐olds pairs of phonetically similar words that contrasted either on one of their consonants or one of their vowels, by either one or two phonological features. Danish was chosen because it has more vowels than consonants, and is characterized by extensive consonant lenition. Both phenomena could disfavor a consonant bias. Evidence of word‐learning was found only for vocalic information, irrespective of whether one or two phonological features were changed. The implication of these findings is that the phonological biases found in early lexical processing are not language‐general but develop during language acquisition, depending on the phonological or lexical properties of the native language. 相似文献

This study investigated relations between pay-for-performance incentives designed to vary in instrumentality (annual pay-for-performance, quarterly pay-for-performance, and base pay level) and employee outcomes (self-reported work effort and turnover intention) in a longitudinal study spanning more than 2 years. After controlling for perceived instrumentality, merit pay increase, and the initial values of the dependent variables, the amount of base pay was positively related to work effort and negatively related to turnover intention, where both relationships were mediated by autonomous motivation. The amounts of quarterly and annual pay-for-performance were both positively related to controlled motivation, but were differently related to the dependent variables due to different relations with autonomous motivation. 相似文献

This study compares the realism of confidence judgments made by individuals and pairs of their answers to general knowledge questions, using a within-subjects design. In the initial Control condition, subjects first answered 30 questions and then confidence rated the chosen answer. For the next 30 questions (Condition 2), they wrote down an argument for the chosen answer and then confidence-rated their answer. In the third condition, the 40 subjects were divided into 20 pairs who then answered and confidence-rated the same 30 questions as in Condition 2. Pair members were asked to collaborate on all parts of the task. The results showed that overconfidence decreased in the Pair condition compared with the Single conditions. Analysis of the interaction in the Pair condition showed a higher overconfidence in those instances where one pair member dominated the interaction totally. Other analyses of the interaction in the Pair condition also supported the importance of argumentation between the pair members for realistic confidence judgments. A comparison with previous research suggests that the fact that the subjects first attempted the questions individually may have increased the proportion correct answers and limited the increase in confidence in the Pair condition. A control study, checking for the effect of subjects answering the same questions twice, found no effect of repetition for any of the three calibration measures used. 相似文献

Choices between positive and negative reinforcement during treatment for escape-maintained behavior.
I G DeLeon P L Neidert B M Anders V Rodriguez-Catter 《Journal of applied behavior analysis》2001,34(4):521-525
Positive reinforcement was more effective than negative reinforcement in promoting compliance and reducing escape‐maintained problem behavior for a child with autism. Escape extinction was then added while the child was given a choice between positive or negative reinforcement for compliance and the reinforcement schedule was thinned. When the reinforcement requirement reached 10 consecutive tasks, the treatment effects became inconsistent and reinforcer selection shifted from a strong preference for positive reinforcement to an unstable selection pattern. 相似文献

Regression among factor scores 总被引:1,自引:0,他引:1
Structural equation models with latent variables are sometimes estimated using an intuitive three-step approach, here denoted
factor score regression. Consider a structural equation model composed of an explanatory latent variable and a response latent
variable related by a structural parameter of scientific interest. In this simple example estimation of the structural parameter
proceeds as follows: First, common factor models areseparately estimated for each latent variable. Second, factor scores areseparately assigned to each latent variable, based on the estimates. Third, ordinary linear regression analysis is performed among the
factor scores producing an estimate for the structural parameter. We investigate the asymptotic and finite sample performance
of different factor score regression methods for structural equation models with latent variables. It is demonstrated that
the conventional approach to factor score regression performs very badly. Revised factor score regression, using Regression
factor scores for the explanatory latent variables and Bartlett scores for the response latent variables, produces consistent
estimators for all parameters. 相似文献

The likelihood of false recall in the Deese-Roediger-McDermott (DRM) paradigm was shown to depend on encoding context in two experiments. When fillers had been preselected to decrease the likelihood of encoding the critical lure's semantic features, false recall was virtually eliminated. However, when the same words were presented rearranged in different presentation orders, levels of false recall that were found in earlier DRM studies (Robinson & Roediger, 1997) were replicated. The role of encoding processes in the DRM paradigm was further explored with additional participants completing the experiment while thinking aloud. During encoding of word lists, participants verbalized semantic elaboration of the critical lure while studying the word lists. A path analysis demonstrated that participants' verbalization of critical lures during encoding reliably predicted their level of false recall. 相似文献

The detrimental phonological similarity effect (PSE), a robust finding in serial recall of words, sometimes reverses with
nonwords. The current study tested the hypothesis that nonwords benefit from phonological similarity because they are harder
to retrieve. In two experiments serial recall and serial reconstruction of visually presented words and nonwords were compared.
Phonological similarity is known to have a positive effect on item memory and a negative effect on position accuracy in serial
recall, and the demands on item retrieval were greatly reduced in the latter task. PSE occurred for words in both tasks and
was reversed for nonwords in serial recall, but not in serial reconstruction—a new finding in the literature. The following
conclusions can be made: (1) the detrimental PSE on order retrieval occurs irrespective of lexicality, in accordance with
prominent short-term memory models; and (2), the positive PSE on item retrieval is crucially affected by lexicality, a finding
less well explained by the existing models. 相似文献
