Individual differences in children's memory and reading comprehension: an investigation of semantic and inhibitory deficits

Three experiments compared the verbal memory skills of children with poor reading comprehension with that of same-age good comprehenders. The aims were to determine if semantic and/or inhibitory deficits explained comprehenders' problems on measures of verbal short-term memory and verbal working memory. In Experiment 1 there were no group differences on word- and number-based measures of short-term storage and no evidence that semantic knowledge mediated word recall. In Experiment 2 poor comprehenders were impaired on word- and number-based assessments of working memory, the greatest deficit found on the word-based task. Error analysis of both word-based tasks revealed that poor comprehenders were more likely to recall items that should have been inhibited than were good comprehenders. Experiment 3 extended this finding: Poor comprehenders were less able to inhibit information that was no longer relevant. Together, these findings suggest that individual differences in inhibitory processing influence the ability to regulate the contents of working memory, which may contribute to the differential memory performance of good and poor comprehenders.     

Reduction of the misinformation effect by arousal induced after learning

Misinformation introduced after events have already occurred causes errors in later retrieval. Based on literature showing that arousal induced after learning enhances delayed retrieval, we investigated whether post-learning arousal can reduce the misinformation effect. 251 participants viewed four short film clips, each followed by a retention test, which for some participants included misinformation. Afterward, participants viewed another film clip that was either arousing or neutral. One week later, the arousal group recognized significantly more veridical details and endorsed significantly fewer misinformation items than the neutral group. The findings suggest that arousal induced after learning reduced source confusion, allowing participants to better retrieve accurate details and to better reject misinformation.     

Scholars’ preferred solutions for research misconduct: results from a survey of faculty members at America’s top 100 research universities

Research misconduct is harmful because it threatens public health and public safety, and also undermines public confidence in science. Efforts to eradicate ongoing and prevent future misconduct are numerous and varied, yet the question of “what works” remains largely unanswered. To shed light on this issue, this study used data from both mail and online surveys administered to a stratified random sample of tenured and tenure-track faculty members (N = 613) in the social, natural, and applied sciences at America’s top 100 research universities. Participants were asked to gauge the effectiveness of various intervention strategies: formal sanctions (professional and legal), informal sanctions (peers), prevention efforts (ethics and professional training), and reducing the pressures associated with working in research-intensive units. Results indicated that (1) formal sanctions received the highest level of support, (2) female scholars and researchers working in the applied sciences favored formal sanctions, and (3) a nontrivial portion of the sample supported an integrated approach that combined elements of different strategies. A key takeaway for university administrators is that a multifaceted approach to dealing with the problem of research misconduct, which prominently features enhanced formal sanctions, will be met with the support of university faculty.     

Right‐wing authoritarianism and social dominance orientation differentially predict biased evaluations of media reports

This study tested the dual‐process motivational (DPM) model, which posits that right‐wing authoritarianism (RWA) and social dominance orientation (SDO) differentially predict attitudes toward socially threatening or subordinate groups, respectively. Participants read articles on same‐sex relationships and affirmative action and evaluated the article content and the biases of the article authors. The article conclusions (i.e., pro‐ or anti‐same‐sex relationships and affirmative action) were varied between subjects. As expected, only RWA predicted evaluations of the same‐sex relationships articles and authors, whereas only SDO predicted evaluations of the affirmative action articles and authors. These results extend applications of the dual‐process model by demonstrating that RWA and SDO differentially predict evaluations of political information that pertains to socially threatening or subordinate groups, respectively.     

A taxonomy of errors in multiple-target visual search

Multiple-target visual searches are especially error prone; once one target is found, additional targets are likely to be missed. This phenomenon, often called satisfaction of search (which we refer to here as subsequent search misses; SSMs), is well known in radiology, despite no existing consensus about the underlying cause(s). Taking a cognitive laboratory approach, we propose that there are multiple causes of SSMs and present a taxonomy of SSMs based on searchers' eye movements during a multiple-target search task, including both previously identified and novel sources of SSMs. The types and distributions of SSMs revealed effects of working memory load, search strategy, and additional causal factors, suggesting that there is no single cause of SSMs. A multifaceted approach is likely needed to understand the psychological causes of SSMs and then to mitigate them in applied settings such as radiology and baggage screening.     

Satisfaction at last: Evidence for the “satisfaction” hypothesis for multiple-target search errors

ABSTRACT

Multiple-target visual searches are susceptible to Subsequent Search Miss (SSM) errors—a reduced accuracy for target detection after a previous target has already been detected. SSM errors occur in critical searches (e.g., evaluations of radiographs and airport luggage x-rays), and have proven to be a stubborn problem. A few SSM theories have been offered, and here we investigate the “satisfaction” account: failing to completely finish a search after having found a first target. Accuracy on a multiple-target search task was compared to both how long participants spent searching after finding a first target and their target sensitivity in a separate vigilance task. Less time spent searching and poor vigilance predicted higher SSM error rates. These results suggest that observers who are more likely to miss a second target are less likely to thoroughly search after finding a first target, thus offering some of the first evidence for the “satisfaction” account.     

Action video game playing is associated with improved visual sensitivity, but not alterations in visual sensory memory

Action video game playing has been experimentally linked to a number of perceptual and cognitive improvements. These benefits are captured through a wide range of psychometric tasks and have led to the proposition that action video game experience may promote the ability to extract statistical evidence from sensory stimuli. Such an advantage could arise from a number of possible mechanisms: improvements in visual sensitivity, enhancements in the capacity or duration for which information is retained in visual memory, or higher-level strategic use of information for decision making. The present study measured the capacity and time course of visual sensory memory using a partial report performance task as a means to distinguish between these three possible mechanisms. Sensitivity measures and parameter estimates that describe sensory memory capacity and the rate of memory decay were compared between individuals who reported high evels and low levels of action video game experience. Our results revealed a uniform increase in partial report accuracy at all stimulus-to-cue delays for action video game players but no difference in the rate or time course of the memory decay. The present findings suggest that action video game playing may be related to enhancements in the initial sensitivity to visual stimuli, but not to a greater retention of information in iconic memory buffers.     

Presurgical Coping, Depression, and Quality of Life in Persons with Parkinson's Disease

This study describes utilization of coping strategies and evaluates the interaction between coping strategies, depression, and quality of life (QOL) in patients with Parkinson's disease (PD) who are being considered for neurosurgical intervention. Eighty patients (mean age 61.7 years) with PD being evaluated for possible deep brain stimulation completed self-report instruments of coping strategies (Coping Responses Inventory), depression (Beck Depression Inventory), and disease-specific QOL (Parkinson's Disease Questionnaire-39). Analyses showed that patients with PD cope with the acute stressor of approaching neurosurgery through a variety of strategies, but particularly avoidant and behavioral strategies. When the correlated but apparently opposing effects of cognitive and behavioral strategies were teased apart, greater use of cognitive strategies was associated with more severe depressive symptomatology (and poorer QOL), while greater use of behavioral strategies appeared to be associated with less depression. Depressive symptomatology, in turn, was associated with poorer QOL. However, coping had minimal direct association with QOL. From this it was concluded that patients with advanced PD generate a variety of coping responses to an acute stressor such as surgery, and the use of behavioral strategies, in particular seeking of alternative enjoyable activities, may be associated with better mood if salutary effects are not overwhelmed by less helpful cognitive coping techniques. The minimization of depressive symptomatology, in turn, is associated with better QOL.     

Managing Emotional Responses in Therapy: An Adapted EFT Supervision Approach

Therapists often encounter experiences in therapy that elicit emotionality, this could be in the form of self-of-the-therapist issues, compassion fatigue, or professional burnout. Whereas approaches to supervision for self-of-the-therapist issues recognize the need for accessing the supervisee’s emotionality, approaches have not focused on how the clinical and professional system could also be part of the cycle. We propose an adapted emotionally focused supervision approach that employs steps one through six of the EFT model. To display how this approach would work, we provide the example of work with longer-term clients. Working with longer-term clients can be a challenge for many therapists, and both the professional and client system come with factors increasing emotional risk to the therapist. Engaging the therapist’s emotionality through supervision has the potential to improve therapeutic outcomes, as well as reduce loss of good therapists in the field to professional burnout.
