An examination of learning processes during critical incident training: implications for the development of adaptable trainees

Three experiments are reported that examined the process by which trainees learn decision-making skills during a critical incident training program. Formal theories of category learning were used to identify two processes that may be responsible for the acquisition of decision-making skills: rule learning and exemplar learning. Experiments 1 and 2 used the process dissociation procedure (L. L. Jacoby, 1998) to evaluate the contribution of these processes to performance. The results suggest that trainees used a mixture of rule and exemplar learning. Furthermore, these learning processes were influenced by different aspects of training structure and design. The goal of Experiment 3 was to develop training techniques that enable trainees to use a rule adaptively. Trainees were tested on cases that represented exceptions to the rule. Unexpectedly, the results suggest that providing general instruction regarding the kinds of conditions in which a decision rule does not apply caused them to fixate on the specific conditions mentioned and impaired their ability to identify other conditions in which the rule might not apply. The theoretical, methodological, and practical implications of the results are discussed.     

Children's printed word database: Continuities and changes over time in children's early reading vocabulary

In this paper we introduce a comprehensive database of the vocabulary in reading materials used by 5 – 9 year old children in the UK. The database is available on‐line http:www.essex.ac.ukpsychologycpwd and allows researchers into early reading development the possibility of rigorous control over critical characteristics of experimental stimuli such as word frequency, regularity and length, frequency of grapheme‐phoneme correspondences, orthographic and phonological neighbourhoods etc. The on‐line database is also a resource that can be used by practitioners with interests in literacy development and literacy instruction. It can be used to obtain characteristics for a user‐generated list of words, or else to generate a list of words according to constraints specified by the user. Here we present an overview of the construction of the database, the materials entered into it, the survey of schools by which we obtained information about the books that were most likely to be used by children in each age group, and the search features available on the database website. We also discuss certain characteristics of the Vocabulary itself and compare these with those reported in an earlier non‐representative database reported in Stuart, Dixon, Masterson and Gray (2003). We then present a detailed analysis of the characteristics of Vocabulary in books used in the Reception year, against the background of recent recommendations for change in the early teaching of reading. Finally, we present data showing that the database is indeed already proving a useful resource for both practitioners and researchers.     

Applied sport psychology: A view from britain

Abstract

Based on the findings of a field study with youth sport coaches, contextual factors in youth sport arc considered. Youth sport is discussed as a “developmental intervention” (Birkel, Lerner, &; Smyer, 1989). Although past research has examined a variety of issues in youth sport (e.g., coaching behavior, participation motivation), the dynamics of the context have been largely ignored. It is argued that situational factors may have important implications for the quality of children's youth sport experiences. Data arc presented to show the significance of contextual factors in coaches' experiences. Examples of previous interventions aimed at manipulating contexts arc offered and suggestions for future interventions, based on the present study, arc discussed. The roles of parents. spectator location. rules, and time are discussed in detail.     

Applications,Implications, Complications: Reply to Reviews by Elkind,Gerson, and Levine

The author appreciates the careful reading and thoughtful reviews by Sue Elkind, Sam Gerson, and Howard Levine. Elkind's review particularly captures and articulates many of the key ideas in the book Building Bridges: The Negotiation of Paradox in Psychoanalysis and creatively applies concepts of negotiation, paradox, an inherently multiple “distributed self,” and metaphor in her own work consulting on treatment impasses. Gerson incisively focuses on the core idea of recognizing, accepting, and bridging differences and contradictions in personal, and national, perspectives; he also articulates an understanding of the attempt of relational analytic writers to bridge the intrapsychic and the interpersonal with due recognition of each. The author replies extensively to Levine's comparison of Pizer's work with that of Semrad and other “classical” analysts and challenges Levine's premise that a relational perspective, grounded as it is in a two-person contextual psychology, ignores or devalues interpretation, insight, free association, and autonomous mental functioning. Quoting from clinical material in his book, Pizer presents the outcome of a “relational” analysis in terms of the patient's increased access to internal “potential space,” unconscious experience, curiosity, and reflectiveness about the mental life of self and other, and an increased ability to value personal experience in relationship and in solitude.     

Is Memory for Head Orientation Based on a Left-Looking Schema?

Research has shown that people misremember right-looking heads on coins as facing to the left, suggesting a general memory schema that favors left-lookers. This hypothesis was investigated in a study of 241 subjects in three experiments who were shown photographs of faces looking to the left, to the right, or at the observer and were later asked to identify whether each one had subsequently been left-right reversed. Also, in Experiments 2 and 3, respectively, initial judgments of liking and of orientation were obtained. Unexpectedly, orientation memory accuracy was lower after a 5-s exposure than after a 1-s exposure, and after initial judgments of lateral orientation than after judgments of liking. Although the difference between left- and right-lookers was significant in only 2 of 14 comparisons, aggregated data showed that identification accuracy was generally higher for left-lookers, with a mean effect size of 0.16. Although small, this difference is consistent with the hypothesis of a left-looking schema for heads.     

Haloperidol-induced Mood and Retrieval of Happy and Unhappy Memories

The present study investigated the effect of haloperidol-induced mood in normal healthy male volunteers on the retrieval of memories of real-life personal experiences using a between-subjects double-blind design. Forty subjects were required to retrieve past real life experiences associated with a series of stimulus words following administration of a single oral dose of 5mg haloperidol or placebo. The experiences were subsequently rated by subjects for their happiness felt at the time of the original experience. A significant decline in self-reported hedonic tone was observed in subjects given haloperidol. In addition, subjects on placebo recalled a significantly greater percentage of happy memories than subjects who were on haloperidol; a trend for a reverse pattern was observed for unhappy memories. The effects of the drug on the retrieval of memories were only in part mediated by the decline in hedonic tone scores. The effects of haloperidol are interpreted in terms of drug-induced dysphoria.     

Matching Methods for Selection of Participants for Follow-Up

This work examines ways to make the best use of limited resources when selecting individuals to follow up in a longitudinal study estimating causal effects. In the setting under consideration, covariate information is available for all individuals but outcomes have not yet been collected and may be expensive to gather, and thus only a subset of the comparison participants are followed. Expressions in Rubin and Thomas (1996) Rubin, D. B. and Thomas, N. 1996. Matching using estimated propensity scores, relating theory to practice.. Biometrics, 52: 249–264. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] show the benefits that can be obtained, in terms of reduced bias and variance of the estimated treatment effect, of selecting comparison individuals well matched to those in the treated group compared with a random sample of comparison individuals. We primarily consider nonexperimental settings but also consider implications for randomized trials. The methods are illustrated using data from the Johns Hopkins University Baltimore Prevention Program, which included data collection from age 6 to young adulthood of participants in an evaluation of 2 early elementary-school-based universal prevention programs.
