Text–Picture Integration: How Delayed Testing Moderates Recognition of Pictorial Information in Multimedia Learning

When learning with multimedia, text and pictures are assumed to be integrated with each other. Arndt, Schüler, and Scheiter (Learning & Instruction, 35, 62–72, 2015) confirmed the process of text picture integration for sentence recognition, not, however, for picture recognition. The current paper investigates the underlying reasons for the latter finding. Two experiments are reported, where subjects memorized text–picture stimuli that differed in the specificity of information contained in either sentences or pictures. In a subsequent picture recognition test, subjects showed no integration effect after a 30‐minute delay (Experiments 1 and 2), but only after a 1‐week delay (Experiment 2). Furthermore, eye‐tracking data showed that participants sufficiently processed the pictures during learning (Experiment 1). This data pattern speaks in favor of the assumption that after a short delay participants had available a short‐lived pictorial surface representation, which masked the integration effect for pictorial recognition.Copyright © 2015 John Wiley & Sons, Ltd.

Brief cognitive behavioral intervention for children and adolescents with persistent post-concussive symptoms: A pilot study

This study aims to evaluate the efficacy of a brief cognitive behavioral intervention program for children and adolescents experiencing persistent post-concussion symptoms. A total of 31 patients aged 10 to 18 years participated in the intervention. The median time since injury at treatment onset was 95 days though the range was large (23–720 days). Treatment was on average four sessions in duration. Sessions included concussion education, activity scheduling, sleep hygiene relaxation training, and cognitive restructuring. Outcomes were measured using symptom reports on the Sports Concussion Assessment Tool – Third Edition (SCAT-3) and parent-reported quality of life on the Pediatric Quality of Life Inventory (PedsQL). Mixed-effects models revealed that symptom reports did not decrease prior to the initiation of this treatment, though significant symptom improvement occurred following treatment. Quality of life scores significantly improved across domains, with the largest gains made in the emotional and school domains. Participant characteristics including age, sex, maternal education, and previous mental health problems were not found to be significantly related to treatment outcomes. Contrary to predictions, length of time since injury was not related to symptom changes. The primary limitation of this study is that it lacks randomization and an experimental control group. The results suggest that brief cognitive behavioral intervention may be a promising treatment for children and adolescents experiencing persistent post-concussive symptoms and warrants further investigation.     

Naïve and Robust: Class‐Conditional Independence in Human Classification Learning

Humans excel in categorization. Yet from a computational standpoint, learning a novel probabilistic classification task involves severe computational challenges. The present paper investigates one way to address these challenges: assuming class‐conditional independence of features. This feature independence assumption simplifies the inference problem, allows for informed inferences about novel feature combinations, and performs robustly across different statistical environments. We designed a new Bayesian classification learning model (the dependence‐independence structure and category learning model, DISC‐LM) that incorporates varying degrees of prior belief in class‐conditional independence, learns whether or not independence holds, and adapts its behavior accordingly. Theoretical results from two simulation studies demonstrate that classification behavior can appear to start simple, yet adapt effectively to unexpected task structures. Two experiments—designed using optimal experimental design principles—were conducted with human learners. Classification decisions of the majority of participants were best accounted for by a version of the model with very high initial prior belief in class‐conditional independence, before adapting to the true environmental structure. Class‐conditional independence may be a strong and useful default assumption in category learning tasks.     

The Health and Well-Being of Military Drone Operators and Intelligence Analysts: A Systematic Review

The aim of this study was to systematically review the existing research on the health and well-being of military drone operators and intelligence analysts in order to provide an overview of research and identify gaps in this area. Six literature databases and 2 databases containing unclassified military reports were searched for relevant papers produced between January 1996 and May 2016. The search criteria were broad to allow for the identification of all relevant studies on the topic. Fifteen studies met the inclusion criteria; all of which were conducted in the U.S. with the U.S. Air Force personnel. The main sources of occupational stress reported by participants across the studies were operational. The rates of mental health diagnoses, including PTSD, were low, but levels of psychological distress were higher in drone and intelligence operators than in comparison groups. Fatigue emerged as a significant concern. It is important that future studies examine a variety of mental and physical health outcomes. The health and well-being of drone operators and intelligence analysts should be studied not just in the U.S., but also in other countries that are using drones for military purposes.     

Health Is Associated With Antiparasite Behavior and Fear of Disease-Relevant Animals in Humans

Evolutionary arms races between humans and parasites resulted in a set of behavioral adaptations that serve as parasite-avoidance mechanisms. We investigated associations among reported health of the respondent, antiparasite behavior, and sensitivity to disgust and fear of disease-relevant and irrelevant animals. Ninety-seven participants (15–19 years old) rated their fear and disgust at 25 colorful pictures of disease-relevant and disease-irrelevant invertebrates. Consistent with previous work, we found that participants reported greater fear and disgust of disease-relevant invertebrates relative to disease-irrelevant invertebrates. Better perceived health correlated with lower fear of disease-relevant invertebrates. Sensitivity to disgust correlated with reported antiparasite behaviors. Contrary to expectations, we found a positive correlation between antiparasite behavior and reported health, which suggests that antiparasite behavior influences perceived health (but not vice versa), and we found that males perform more antiparasite behaviors than females. These results support the idea that disgust and fear of disease-relevant objects are adaptive emotions that prevent contact with contagious objects, especially in individuals with low perceived health.     

More of myself: Manipulating interoceptive awareness by heightened attention to bodily and narrative aspects of the self

Psychology distinguishes between a bodily and a narrative self. Within neuroscience, models of the bodily self are based on exteroceptive sensorimotor processes or on the integration of interoceptive sensations. Recent research has revealed interactions between interoceptive and exteroceptive processing of self-related information, for example that mirror self-observation can improve interoceptive awareness. Using heartbeat perception, we measured the effect on interoceptive awareness of two experimental manipulations, designed to heighten attention to bodily and narrative aspects of the self. Participants gazed at a photograph of their own face or at self-relevant words. In both experimental conditions interoceptive awareness was significantly increased, compared to baseline. Results show that attention to narrative aspects of self, previously regarded as relying on higher-order processes, has an effect similar to self-face stimuli in improving interoceptive awareness. Our findings extend the previously observed interaction between the bodily self and interoception to more abstract amodal representations of the self.     

Philosophical Sensitivity

Although much has been written about the nature of philosophy and how the discipline can be defined, little attention has been paid to the ways we develop the facility to reflect philosophically or why cultivating this ability is valuable. This article develops a conception of “philosophical sensitivity,” a perceptual capacity that facilitates our awareness of the philosophical dimension of experience. Based in part on Aristotle's notion of a moral perceptual capacity, philosophical sensitivity starts with most people's natural inclinations as children to reflect about life's fundamental mysteries; when this capacity is cultivated with training over time, our attentiveness to the philosophical features of ordinary life becomes almost second nature. In much the same way an aesthetically sensitive person notices certain qualities of experience not readily perceptible by others, philosophical sensitivity involves the development of a particular way of seeing the world.     

Body Image Preference in the United States and Rural Thailand: An Exploratory Study

The authors conducted a field study to examine the female body image preferences of young women and young men in a rural northern province of Thailand and in central California. The Thai participants did not have stronger body image preferences than did the U.S. participants overall. However, the young women preferred a significantly more slender body image than did the young men, F(1, 80) = 14.98, p < .001, and the Respondent Gender x Nationality interaction was also significant, F(1, 80) = 4.42, p = .039. Thai men, as expected, exhibited preferences for figures that were heavier than those preferred by their U.S. counterparts. Thai women, in contrast, exhibited preferences for figures that were thinner than those preferred by their U.S. counterparts or their male countrymen. These results are explained in terms of traditional Thai and U.S. values and in terms of Western cultural influences in modern Thailand.
