The Contribution of Executive Skills to Reading Comprehension

Although word recognition deficits (WRD) are a known cause of reading comprehension deficits (RCD), other contributions to RCD, including executive function (EF), have not been fully explored. We examined the contribution of EF (working memory and planning), along with attention, decoding, fluency, and vocabulary to reading comprehension in 60 children (including 16 WRD and 10 RCD), ages 9–15 years. After controlling for commonly accepted contributors to reading comprehension (i.e., attention, decoding skills, fluency, and vocabulary), EF continued to make a significant contribution to reading comprehension but not to word recognition skills. These findings highlight the need for consideration of the role of EF in RCD.     

Egocentric framing — One way people may fail in a switch dilemma: Evidence from excessive lane switching

To study switching behavior, an experiment mimicking the state of a driver on the road was conducted. In each trial participants were given a chance to switch lanes. Despite the fact that lane switching had no sound rational basis, participants often switched lanes when the speed of driving in their lane on the previous trial was relatively slow. That tendency was discerned even when switching behavior had been sparsely reinforced, and was especially marked in almost a third of the participants, who manifested it consistently. The findings illustrate a type of behavior occurring in various contexts (e.g., stocks held in a portfolio, conduct pertinent for residual life expectancy, supermarket queues). We argue that this behavior may be due to a fallacy reminiscent of that arising in the well-known “envelopes problem”, in which each of two players holds a sum of money of which she knows nothing about except that it is either half or twice the amount held by the other player. Players may be paradoxically tempted to exchange assets, since an exchange fallaciously appears to always yield an expected value greater than whatever is regarded as the player's present assets. We argue that the fallacy is due to egocentrically framing the problem as if the “amount I have” is definite, albeit unspecified, and shows that framing the paradox acentrically instead eliminates the incentive to exchange assets. A possible psychological source for the human disposition to frame problems in a way that inflates expected gain is discussed. Finally, a heuristic meant to avert the source of the fallacy is proposed.     

Ten years of career success in relation to individual and situational variables from the employee development literature

Individual, situational, and socio-demographic variables from the employee development literature were combined with theory and research on career success in a ten-year study of 289 workers from across many jobs and industries in the workforce. Support for employee development by one's employer ten years prior and a trend of increasing/accumulating support contributed to career success, providing the first long-term confirmation of the value to careers from support for development by employers. Proactive personality had unique effects on success not accounted for by a broad array of other variables, strengthening conclusions from prior research about the predictive value of proactive personality which were based on data not controlling for these variables. Finally, achievement goal orientation influenced success in a unique way via “profile effects:” Goal orientation dimensions interacted to predict success, suggesting simple linear effects (e.g. being more learning-oriented) may be inadequate in explaining career success. Implications for future research and practice are discussed.     

Anxiety Sensitivity and Interoceptive Exposure: A Transdiagnostic Construct and Change Strategy

Recent findings support the relevance of anxiety sensitivity (AS) and interoceptive exposure (IE) across emotional disorders. This study (a) evaluated levels of AS across different anxiety disorders, (b) examined change in AS over the course of transdiagnostic psychological intervention, and its relationship with outcome, and (c) described the implementation of IE to address AS with patients with different anxiety disorders. Participants (N = 54) were patients who received treatment with the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) in two consecutive treatment trials. Participants completed a measure of AS at pre- and posttreatment, and multiple occasions during treatment. Symptom severity was assessed at pre- and posttreatment, and clinical information related to physical symptoms and IE were collected as part of routine clinical practice. Elevated AS was observed at pretreatment across diagnoses and decreases in AS were observed from pre- to posttreatment. Similar changes occurred across the diagnostic categories, notably coinciding with the introduction of IE. Change in AS was correlated with reduced symptom levels at posttreatment and 6-month follow-up. Patients with different anxiety disorders endorsed similar physical symptoms and practiced similar IE exercises with similar effects. Results provide preliminary support for the usefulness of IE as a treatment strategy across the spectrum of anxiety disorders, and additional support for the transdiagnostic relevance of AS.     

A unified approach to multiple‐set canonical correlation analysis and principal components analysis

Multiple‐set canonical correlation analysis and principal components analysis are popular data reduction techniques in various fields, including psychology. Both techniques aim to extract a series of weighted composites or components of observed variables for the purpose of data reduction. However, their objectives of performing data reduction are different. Multiple‐set canonical correlation analysis focuses on describing the association among several sets of variables through data reduction, whereas principal components analysis concentrates on explaining the maximum variance of a single set of variables. In this paper, we provide a unified framework that combines these seemingly incompatible techniques. The proposed approach embraces the two techniques as special cases. More importantly, it permits a compromise between the techniques in yielding solutions. For instance, we may obtain components in such a way that they maximize the association among multiple data sets, while also accounting for the variance of each data set. We develop a single optimization function for parameter estimation, which is a weighted sum of two criteria for multiple‐set canonical correlation analysis and principal components analysis. We minimize this function analytically. We conduct simulation studies to investigate the performance of the proposed approach based on synthetic data. We also apply the approach for the analysis of functional neuroimaging data to illustrate its empirical usefulness.     

Working with psychosis: Part 2 – encounters with an omnipotent super-ego

This is the second in a series of four papers presenting work with a man suffering from a bipolar disorder. The present paper describes the second year of the work and my encounters with an omnipotent super-ego which made ferocious attacks on the work, especially when there were any developments. The attacks were particularly disabling because my own implacable super-ego was mobilized in the counter-transference. Consequently developments seemed to melt away as my patient and I were often reduced to mindless states. I came to understand that these omnipotent attacks were stirred by feelings of infantile helplessness and dependency, and were a means of trying to manage a dread of falling to pieces and unintegration.     

Does category labeling lead to forgetting?

What effect does labeling an object as a member of a familiar category have on memory for that object? Recent studies suggest that recognition memory can be negatively impacted by categorizing objects during encoding. This paper examines the “representational shift hypothesis” which argues that categorizing an object impairs recognition memory by altering the trace of the encoded memory to be more similar to the category prototype. Previous evidence for this idea comes from experiments in which a basic-level category labeling task was compared to a non-category labeling incidental encoding task, usually a preference judgment (e.g., “Do you like this item?”). In two experiments, we examine alternative tasks that attempt to control for processing demands and the degree to which category information is explicitly recruited at the time of study. Contrary to the predictions of the representational shift hypothesis, we find no evidence that memory is selectively impaired by category labeling. Overall, the pattern of results across both studies appears consistent with well-established variables known to influence memory such as encoding specificity and distinctiveness effects.     

Influence of response time frame on mood assessment

Abstract

Dental anxiety and the related avoidance of dental treatment can result in severe impairment of health. We investigated the influence on avoidance behavior of phobic severity, gender, characteristics related to generalized anxiety and depression, such as dysfunctional cognitions and sensitivity of bodily symptoms, as well as personality traits of self-efficacy and locus of control. Forty-eight dental phobics were given an initial assessment and avoidance behavior was determined by the degree of observance of three subsequent dental appointments. Principal component analysis revealed separate factors for trait and phobic anxiety as well as for avoidance and dysfunctional cognitions. Women showed a higher degree of avoidance than men. Regression analysis revealed a high desire for control over dental treatment combined with a low level of perceived control as the only significant predictor variable of avoidance. The results suggest that avoidance behavior in dental phobia could be reduced by extending patients’ control over treatment conditions.
