Item to decision mapping in rapid response learning

Repeated classification of a visually presented stimulus rapidly leads to a form of response learning that bypasses the original evaluation in favor of a more efficient response mechanism. In two experiments, we examined the level of input and output representations that make up this form of learning. In Experiment 1, alterations in the finger mapping of the output response had no effect on the expression of response learning, demonstrating that a classification decision, not motor output, is associated with repeated items. In Experiments 2A and 2B, we tested whether response learning would transfer across different visual exemplars of a studied item. There was no evidence of transfer to different visual exemplars, even when these exemplars were judged to be highly visually similar. Taken together, these results indicate that response learning consists of the formation of an association between a specific visual representation and a classification decision.     

Does a Marriage Ideal Exist? Using Q-Sort Methodology to Compare Young Adults’ and Professional Educators’ Views on Healthy Marriages

This study sought to understand whether young adults and family educators share beliefs about the components of a successful relationship. Young adults viewed successful relationships as having partners who agree on most issues. Educators characterized successful partners as exhibiting positive communication patterns and using relationship maintenance strategies. A third prototype included young adults and educators who described successful relationships in terms of agreement and problem solving behaviors. Implications for researchers and practitioners conclude the article.     

"If you want me to treat you like an adult, start acting like one!" Comparing the criteria that emerging adults and their parents have for adulthood.

The purpose of this study was (a) to identify the criteria parents of emerging adults consider necessary and important for their children to achieve adulthood, (b) to compare parents' criteria for adulthood with the criteria espoused by emerging adults, and (c) to examine how these criteria might differ on the basis of gender of the parent and gender of the child. Participants included 392 unmarried college students, ages 18-25, and at least 1 of their parents (271 fathers, 319 mothers). Results revealed that (a) as did their children, most parents did not yet view their children as adults, (b) there was disagreement between children and their parents in the emphasis they placed on various criteria for adulthood, (c) mothers and fathers did not always agree on the importance of various criteria, and (d) the gender of both the parent and the child played a role in the criteria parents deemed important for adulthood. Taken together, the findings suggest that parents and children view the transition to adulthood differently, which might have implications for the parent-child relationship during this period of development.     

Driving after use of alcohol and marijuana in college students.

Driving after use of marijuana is almost as common as driving after use of alcohol in youth (P. M. O'Malley & L. D. Johnston, 2003). The authors compared college students' attitudes, normative beliefs and perceived negative consequences of driving after use of either alcohol or marijuana and tested these cognitive factors as risk factors for substance-related driving. Results indicated that youth perceived driving after marijuana use as more acceptable to peers and the negative consequences as less likely than driving after alcohol use, even after controlling for substance use. Results of zero-inflated Poisson regression analyses indicated that lower perceived dangerousness and greater perceived peer acceptance were associated with increased engagement in, and frequency of, driving after use of either substance. Lower perceived likelihood of negative consequences was associated with increased frequency for those who engage in substance-related driving. These results provide a basis for comparing how youth perceive driving after use of alcohol and marijuana, as well as similarities in the risk factors for driving after use of these substances.     

Prevalence of poor psychological morbidity following a minor road traffic accident (RTA): The clinical implications of a prospective longitudinal study

Few Road Traffic Accident (RTA) victims have their psychological needs attended to in hospital or afterwards. We conducted a small-scale preliminary investigation exclusively focussing on the prevalence of poor psychological morbidity following minor road traffic accidents (RTAs). Participants (N?=?50) completed assessments one-month after their minor RTA and (N?=?39) at 4-months follow-up. The identification of clinically significant anxiety, depression and post traumatic stress disorder (PTSD) in this minor RTA sample supports both evidence reported elsewhere and our specific predictions. Seven (14%) participants at baseline and five (12.8%) at follow-up met diagnostic criteria for PTSD. The clinical implications for identifying and meeting the psychological needs of minor RTA victims are discussed in the context of cognitive behavioural conceptualizations of mental disorder.     

Dissociative tendencies and memory performance on directed-forgetting tasks

The current article presents two studies that aimed to replicate DePrince and Freyd's (2001, 2004) studies demonstrating that high and low dissociators differentially recall neutral and trauma words under conditions of varying cognitive load. We did not find this effect. This lack of replication was apparent for both free recall and word recognition memory and in both studies. In effect, we found little evidence to support betrayal trauma theory, yet observed increased memory fallibility, as demonstrated by lower general recall and (in one study) commission errors, in high dissociators.     

Better the DVL you know: acronyms reveal the contribution of familiarity to single-word reading

Current theories of reading are divided between dual-route accounts, which propose that separable processes subserve word recognition for orthographically regular and irregular strings, and connectionist models, which propose a single mechanism mapping form to meaning. These theories make distinct predictions about the processing of acronyms, which can be orthographically illegal and yet familiar, as compared with the processing of pseudowords, which are regular but unfamiliar. This study examined whether acronyms are processed like pseudowords and words. Event-related potentials (ERPs) were recorded as subjects viewed familiar and unfamiliar acronyms, words, pseudowords, illegal strings, and--as the targets of the substantive behavioral task--proper names. Familiar acronyms elicited repetition effects on the N400 component, a functionally specific index of semantic activation processes; repetition effects for familiar acronyms were similar in magnitude, timing, and scalp distribution to those for words and pseudowords. The similarity of the brain response to familiar--but--illegal and unfamiliar--but--legal classes of stimuli is inconsistent with predictions of dual-route models of reading.     

Using cue words to investigate the distribution of autobiographical memories in childhood

The cue-word technique is frequently used with adults to examine the distribution of autobiographical memories across the life span. Such studies demonstrate childhood amnesia: a paucity of memories of events from the first 3(1/2) years of life, and a gradually increasing number of memories from age 3 to age 7. The pattern is remarkable in light of findings of autobiographical competence among children in the period of life eventually obscured by this amnesia. In the present study, we modified the cue-word task for use with school-age children. Seven- to 10-year-olds successfully generated and dated memories of past events. Girls provided more complete narratives than boys. Across the sample, the resulting distribution of memories was better fit by an exponential than by a power function, implying that early memories may not consolidate and instead remain vulnerable to interference. Implications for explanations of childhood amnesia are discussed.     

To Be,or Not to Be,Linear: An expanded representation of personality and its relationship to leadership performance

In this study, we tested for a set of complex, nonlinear relationships between derailing/dark side personality composites and leadership performance using two independent samples of managers/leaders (N=1306 and N=290 for Study 1 and 2, respectively). Based on the structure and characteristics of the derailing/dark side trait composites, we expected the relationship between these composites and leadership performance would best be described with an inverted U function. In Study 1, we found evidence of a nonlinear relationship between the derailing composite, as measured by the Global Personality Inventory^©, and behaviorally based, structured ratings of leadership performance in an assessment center. Similarly, Study 2 found evidence for a nonlinear relationship between dark side composites, as measured by the Hogan Development Survey^©, and supervisory/other ratings of leadership performance. We discuss the implications of these complex, nonlinear findings with respect to the continued use of personality for the selection and promotion of future leaders. Limitations of the current study and directions for future research are noted.
