SOCIAL COMPARISONS AND CONTENTMENT Exploring the Psychological Costs of the Gender Wage Gapi

This study explored the role of social comparison processes in fostering contentment among those who are objectively disadvantaged. We focus on how comparisons can produce gender differences in personal entitlement, perceptions of one's own performance, and pay satisfaction. We hypothesized that individuals would base judgments of entitlement, performance, and pay satisfaction more on comparisons with ingroup (same-sex) than outgroup (cross-sex) others, even when both types of comparison information were equally available, unavoidable, and made clear the disadvantaged status of the ingroup. As predicted, the amount students felt they were entitled to be paid, how well they thought they had performed (women only), and how satisfied they were with their pay were all influenced more by same-sex than cross-sex comparison information. The implications of these results for the tolerance of injustice among disadvantaged groups are discussed.     

Wild hummingbirds rely on landmarks not geometry when learning an array of flowers

Rats, birds or fish trained to find a reward in one corner of a small enclosure tend to learn the location of the reward using both nearby visual features and the geometric relationships of corners and walls. Because these studies are conducted under laboratory and thereby unnatural conditions, we sought to determine whether wild, free-living rufous hummingbirds (Selasphorus rufus) learning a single reward location within a rectangular array of flowers would similarly employ both nearby visual landmarks and the geometric relationships of the array. Once subjects had learned the location of the reward, we used test probes in which one or two experimental landmarks were moved or removed in order to reveal how the birds remembered the reward location. The hummingbirds showed no evidence that they used the geometry of the rectangular array of flowers to remember the reward. Rather, they used our experimental landmarks, and possibly nearby, natural landmarks, to orient and navigate to the reward. We believe this to be the first test of the use of rectangular geometry by wild animals, and we recommend further studies be conducted in ecologically relevant conditions in order to help determine how and when animals form complex geometric representations of their local environments.     

Multidimensional Suicide Inventory-28 (MSI-28) Within a Sample of Military Basic Trainees: An Examination of Psychometric Properties

Suicide and suicidal ideation are serious public health concerns. Accurate detection and assessment are critical first steps in addressing this challenging issue. The present study examined self-reported suicidal ideation in a sample of United States Air Force enlisted active duty basic trainees (N = 470) using the Multidimensional Suicide Inventory (MSI-28). Exploratory factor analyses revealed a 4-factor structure for the MSI-28 in this sample. Together, these 4 factors explained approximately 72% of the variance in the MSI-28. The MSI-28 evidenced moderate to strong associations with measures of resilience (Dispositional Resilience Scale-15; DRS-15) and psychological distress (Outcome Questionnaire; OQ-30.2). These findings demonstrate that the MSI-28 is a promising tool for clinical measurement of self-reported suicidality. Future directions for further validation of the MSI-28 are discussed.     

The Impact of a Precision Teaching Intervention on the Reading Fluency of Typically Developing Children

This research investigated the efficacy of precision teaching (PT) on the reading fluency of typically developing children, aged 7–8 years. Seven participants were assigned to a PT intervention group and received 6 weeks of fluency training using Say All Fast a Minute Every Day Shuffled (SAFMEDS) fluency cards (Phase 1) and a Dolch story (Phase 2). Outcomes were measured using multiple baseline design (MBD) data, Standard Celeration Charts, and pre‐intervention–post‐intervention fluency scores. The MBD data show increased correct responding for PT participants from baseline to the end of each intervention phase. These improvements were maintained at a 3‐week post‐intervention follow‐up. The MBD clearly demonstrated a replication of intervention effects across participants. The study supports prior research in this area showing that PT can lead to large and socially relevant gains in children's reading fluency. Copyright © 2015 John Wiley & Sons, Ltd.     

Efficacy of neurostimulation to treat symptoms of Mal de Debarquement Syndrome. A preliminary study using repetitive transcranial magnetic stimulation

Mal de debarquement syndrome (MdDS) is a rare and poorly understood condition of perceived continual motion. Using a multiple‐case design (n = 13; 8 f; 63.5 ± 12.6 years), this study investigated the efficacy of eight 20‐min sessions, over 4 weeks, of repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral pre‐frontal cortex. Compared to sham, rTMS demonstrated improvement in balance and confidence in daily living activities. rTMS shows promise for the treatment of MdDS. However, larger trials with longer intervention periods are required.     

Processing of audiovisually congruent and incongruent speech in school‐age children with a history of specific language impairment: a behavioral and event‐related potentials study

Previous studies indicate that at least some aspects of audiovisual speech perception are impaired in children with specific language impairment (SLI). However, whether audiovisual processing difficulties are also present in older children with a history of this disorder is unknown. By combining electrophysiological and behavioral measures, we examined perception of both audiovisually congruent and audiovisually incongruent speech in school‐age children with a history of SLI (H‐SLI), their typically developing (TD) peers, and adults. In the first experiment, all participants watched videos of a talker articulating syllables ‘ba’, ‘da’, and ‘ga’ under three conditions – audiovisual (AV), auditory only (A), and visual only (V). The amplitude of the N1 (but not of the P2) event‐related component elicited in the AV condition was significantly reduced compared to the N1 amplitude measured from the sum of the A and V conditions in all groups of participants. Because N1 attenuation to AV speech is thought to index the degree to which facial movements predict the onset of the auditory signal, our findings suggest that this aspect of audiovisual speech perception is mature by mid‐childhood and is normal in the H‐SLI children. In the second experiment, participants watched videos of audivisually incongruent syllables created to elicit the so‐called McGurk illusion (with an auditory ‘pa’ dubbed onto a visual articulation of ‘ka’, and the expectant perception being that of ‘ta’ if audiovisual integration took place). As a group, H‐SLI children were significantly more likely than either TD children or adults to hear the McGurk syllable as ‘pa’ (in agreement with its auditory component) than as ‘ka’ (in agreement with its visual component), suggesting that susceptibility to the McGurk illusion is reduced in at least some children with a history of SLI. Taken together, the results of the two experiments argue against global audiovisual integration impairment in children with a history of SLI and suggest that, when present, audiovisual integration difficulties in this population likely stem from a later (non‐sensory) stage of processing.
