Children's Production of Unfamiliar Word Sequences Is Predicted by Positional Variability and Latent Classes in a Large Sample of Child-Directed Speech

We explore whether children's willingness to produce unfamiliar sequences of words reflects their experience with similar lexical patterns. We asked children to repeat unfamiliar sequences that were identical to familiar phrases (e.g., A piece of toast) but for one word (e.g., a novel instantiation of A piece of X, like A piece of brick). We explore two predictions-motivated by findings in the statistical learning literature-that children are likely to have detected an opportunity to substitute alternative words into the final position of a four-word sequence if (a) it is difficult to predict the fourth word given the first three words and (b) the words observed in the final position are distributionally similar. Twenty-eight 2-year-olds and thirty-one 3-year-olds were significantly more likely to correctly repeat unfamiliar variants of patterns for which these properties held. The results illustrate how children's developing language is shaped by linguistic experience.     

Illustrating a Hierarchical Approach for Selecting Personality Traits in Personnel Decisions: An Application of the 3M Model

Recent research indicates that managers are not aware of the latest developments in theory regarding the use of personality inventories in personnel selection decisions. This article presents a systematic approach to selecting traits for use in personnel selection that is based on recent developments in hierarchical personality models. Results from a study of real estate sales associates indicate that the new approach does have much to offer the area. Results are discussed along with managerial implications.     

An extension of the exemplar-based random-walk model to separable-dimension stimuli

An extension of Nosofsky and Palmeri's (Psychol. Rev. 104 (1997a) 266) exemplar-based random-walk (EBRW) model of categorization is presented as a model of the time course of categorization of separable-dimension stimuli. Nosofsky and Palmeri (1997a) assumed that the perceptual encoding of all stimuli was identical. However, in the current model, we assume as in Lamberts (J. Exp. Psychol.: General 124 (1995) 161) that the inclusion of individual stimulus dimensions into the similarity calculations is a stochastic process with the probability of inclusion based on the perceptual salience of the dimensions. Thus, the exemplars that enter into the random-walk change dynamically during the time course of processing. This model is implemented as a Markov chain. Its predictions are compared with alternative models in a speeded categorization experiment with separable-dimension stimuli.     

Changes in attachment orientations across the transition to parenthood

According to attachment theory, individuals should experience changes in attachment orientations (styles) if they encounter experiences or events that strongly reinforce or directly contradict the major concerns of their existing orientations. Systematic changes should be most evident across stressful life transitions. Wives and husbands expecting their first child completed scales measuring their attachment orientations along with perceptions of themselves, their spouses, and their marriage both 6 weeks before and 6 months after childbirth. As predicted, women became more ambivalent across the transition if they entered parenthood perceiving less spousal support and more spousal anger, with perceptions of anger having stronger impact. Women who entered parenthood seeking less spousal support and those whose husbands were higher in avoidance became more avoidant across the transition. Men who perceived themselves as providing more prenatal support to their wives became less avoidant. These results extend attachment theory and research in novel directions.     

Models Clarified: Responding to Langdon Gilkey

We respond to concerns raised by Langdon Gilkey. The discussion addresses the nature of theological thinking today, the question of truth within the situation of pluralism, the identity and difference between theological models and scientific models, and the proposed methods for testing theological models.     

Reducing ethnic prejudice: an evaluation of seven recommended principles for incorporation in public campaigns

The present study investigated the effects of seven principles drawn from cognitive models of ethnic prejudice, general information processing models and persuasion models, on levels of ethnic prejudice. It was hypothesized that exposure to cue cards incorporating these principles would result in lower levels of prejudice than cue cards which did not incorporate the principles. A total of 400 caucasian participants were randomly assigned to experimental conditions (where participants were exposed to a cue card incorporating or omitting each of the seven principles), or the control condition (with no cue card exposure), and completed a questionnaire measuring ethnic prejudice. Results revealed that the absence of the principles in the cards led in several cases to unwanted negative effects (higher levels of prejudice than the control group). Reasons for these findings and implications for launching poster campaigns to reduce ethnic prejudice are discussed. Copyright © 2003 John Wiley & Sons, Ltd.     

On growth curves and mixture models

The multilevel model of change and the latent growth model are flexible means to describe all sorts of population heterogeneity with respect to growth and development, including the presence of sub‐populations. The growth mixture model is a natural extension of these models. It comes at hand when information about sub‐populations is missing and researchers nevertheless want to retrieve developmental trajectories from sub‐populations. We argue that researchers have to make rather strong assumptions about the sub‐populations or latent trajectory classes in order to retrieve existing population differences. A simulated example is discussed, showing that a sample of repeated measures drawn from two sub‐populations easily leads to the mistaken inference of three sub‐populations, when assumptions are not met. The merits of methodological advises on this issue are discussed. It is concluded that growth mixture models should be used with understanding, and offer no free way to growth patterns in unknown sub‐populations. Copyright © 2006 John Wiley & Sons, Ltd.     

The crisis of psychoanalysis and psychoanalytical training: The suffering of the candidate on the long road towards qualifi cation1

The author assesses the impact of the so‐called ‘crisis of psychoanalysis’ on the training of candidates, and on those who accompany them through the course. Different causes of the most relevant symptom of the crisis, i.e. the diffi culty of fi nding patients for a four‐sessions‐weekly analysis, are considered. According to the author, analysts themselves must bear some of the responsibility for it. She draws attention to a number of interrelated phenomena, such as: trainees' tension in their encounters with potential analysands, due to awareness of their own needs as trainees; the necessity to accept very disturbed patients whose selection might arouse criticism from the training committee; analyses in which trainees seem to become patients' hostages because of ever‐present fears of interruption; the diffi cult construction of a psychoanalytic identity in trainees who also are in full‐time psychiatric practice; trainees' profound uncertainty about the future both of psychoanalysis in general and their own careers in particular. In agreement with Kernberg, the author stresses the importance of considering the ‘crisis of psychoanalysis’ as a phenomenon whose development may be infl uenced by the analysts themselves.
