Children's memories of experienced and nonexperienced events following repeated interviews

The present study compared 3- and 5-year-olds' reports of a true or false play interaction following repeated interviews. Final interviews were conducted either by the same researcher or by a new researcher. Age-related improvements in performance were evident. Also, 3-year-olds questioned repeatedly about an entirely false event made more errors in response to specific questions than 3-year-olds questioned repeatedly about false details of a true event. Five-year-olds who were questioned about the false event, however, were particularly accurate when answering questions about never-experienced body touch. Interviewer familiarity was associated with decreases in the amount of narrative detail 5-year-olds provided in free-recall and with increases in 3-year-olds' accuracy in response to direct questions. Both errors and response latency on a cognitive matching task were related to children's suggestibility.     

Five-factor model (Big Five) personality traits and universal-diverse orientation in counselor trainees

In this study the authors explored the relationship between five-factor model (FFM: Big Five) personality traits (J. M. Digman, 1990; R. R. McCrae & O. P. John, 1992; J. S. Wiggins & P. D. Trappnell, 1997) and universal-diverse orientation (UDO; M. L. Miville et al., 1999) in counselor trainees. FFM traits were measured using the NEO-Personality Inventory-Revised (P. T. Costa & R. R. McCrae, 1992). Statistically significant relationships were found between UDO and one of the Big Five personality traits (Openness to Experience) in counselor trainees. Further regression analysis suggested a relationship between UDO and a particular facet of Openness to Experience, Openness to Aesthetics. This finding suggests that counselor trainees who are open to the creative expressions of others may be comfortable working with a wide variety of clients. These results suggest that counselor training that encourages experiences of aesthetic diversity in addition to an exploration of values may promote trainees' ability to work with diverse clients.     

The role of pictorial convention in haptic picture perception

An investigation of tactile picture perception is reported. Blindfolded sighted subjects explored either 'line drawings' or 'textured' tactile pictures produced on Zytex swell paper. All pictures were 'two-dimensional', that is they depicted only one object face and so did not represent a third dimension. Both picture sets represented the same objects. Results revealed that the textured pictures, in which solid surfaces of depicted objects were uniformly textured, were recognised more often than tactile line drawings, in which surfaces of objects were simply bounded by lines. There were no significant correlations between imagery ability (visual, cutaneous, or kinaesthetic) and picture recognition success. Texture may be a form of 'uniform connectedness' (Palmer and Rock 1994 Psychonomic Bulletin & Review 1 29-55) or 'common region' (Palmer 1992 Cognitive Psychology 24 436-447), highlighting the global characteristics of stimuli. We argue that textured pictures may encourage the haptic system to take a more globally oriented approach to tactile picture perception, benefiting recognition.     

On specifying the null model for incremental fit indices in structural equation modeling

In structural equation modeling, incremental fit indices are based on the comparison of the fit of a substantive model to that of a null model. The standard null model yields unconstrained estimates of the variance (and mean, if included) of each manifest variable. For many models, however, the standard null model is an improper comparison model. In these cases, incremental fit index values reported automatically by structural modeling software have no interpretation and should be disregarded. The authors explain how to formulate an acceptable, modified null model, predict changes in fit index values accompanying its use, provide examples illustrating effects on fit index values when using such a model, and discuss implications for theory and practice of structural equation modeling.     

Forms of resistance: Foucault on tactical reversal and self-formation

This paper argues that two distinct models of resistance are to be found in Foucault's work. The first, tactical reversal, is predicated on the idea that conflict is inherent to power relations, the strategical model of power, and thus that a specific configuration of power and knowledge can be thwarted by reversing the mechanisms whereby this relation is sustained. The second, the aesthetics of existence, is based in the governmental model of power and holds that it is possible to forge autonomous forms of life in and through such techniques of governance. I argue that Foucault came to favor the latter of these two alternatives because the model of power underlying resistance as tactical reversal proved insufficient both historically and conceptually. It was thus on this basis that he was able to work out the governmental conception of power relations and thereby accord a fundamental role to the concept of resistance as autonomy or self-formation. The key to understanding how this project is not only practical, but is also our obligation lies in the genealogy of the critical attitude that Foucault was developing in his final years.     

Expectancies generated by recent exposure to melodic sequences

In four experiments, we examined the effects of exposure to unfamiliar tone sequences on melodic expectancy and memory. In Experiment 1, 30 unfamiliar tone sequences (target sequences) were presented to listeners three times each in random order (exposure phase), and listeners recorded the number of notes in each sequence. Listeners were then presented target and novel sequences and rated how well the final note continued the pattern of notes that preceded it. Novel sequences were identical to target sequences, except for the final note. Ratings were significantly higher for target sequences than for novel sequences, illustrating the influence of exposure on melodic expectancy. Experiment 2 confirmed that without exposure to target sequences, ratings were equivalent for target and novel sequences. In Experiment 3, new listeners were assessed for explicit memory for target sequences following the exposure phase. Recognition of target sequences was above chance, but unrelated to expectancy judgments in Experiment 1. Experiment 4 replicated the exposure effect, using a modified experiment design, and confirmed that the effect is not dependent on explicit memory for sequences. We discuss the idea that melodic expectancies are influenced by implicit memory for recently heard melodic patterns.     

Response acquisition under direct and indirect contingencies of reinforcement

We compared the effects of direct and indirect reinforcement contingencies on the performance of 6 individuals with profound developmental disabilities. Under both contingencies, completion of identical tasks (opening one of several types of containers) produced access to identical reinforcers. Under the direct contingency, the reinforcer was placed inside the container to be opened; under the indirect contingency, the therapist held the reinforcer and delivered it to the participant upon task completion. One participant immediately performed the task at 100% accuracy under both contingencies. Three participants showed either more immediate or larger improvements in performance under the direct contingency. The remaining 2 participants showed improved performance only under the direct reinforcement contingency. Data taken on the occurrence of "irrelevant" behaviors under the indirect contingency (e.g., reaching for the reinforcer instead of performing the task) provided some evidence that these behaviors may have interfered with task performance and that their occurrence was a function of differential stimulus control.
