Objective: Hundreds of scientific publications are produced annually that involve the measurement of cortisol in saliva. Intra- and inter-laboratory variation in salivary cortisol results has the potential to contribute to crossstudy inconsistencies in findings, and the perception that salivary cortisol results are unreliable. This study rigorously estimates sources of measurement variability in the assay of salivary cortisol within and between established international academic-based laboratories that specialize in saliva analyses. One hundred young adults (Mean age: 23.10 years; 62 females) donated 2 mL of whole saliva by passive drool. Each sample was split into multiple- 100 μL aliquots and …

School-based concussion management programs cover thousands of young athletes, yet there is little in the way of research to assess program processes or outcomes. This study examined the referral patterns of consultants working with ten high school concussion management programs. In addition to the number of referrals made to specialists, other potential outcome variables were explored. The sample included over 5,000 athlete-seasons and 298 concussions managed directly by certified athletic trainers. All programs used computerized neuropsychological testing (both baseline and post injury). Two groups were compared: five programs used a clinical neuropsychologist (NP) as the testing consultant and five used …

Chronic ankle instability (CAI) is often debilitating and may be affected by a number of intrinsic and environmental factors. Alterations in neurocognitive function and attention may contribute to repetitive injury in those with CAI and influence postural control strategies. Thus, the purpose of this study was to determine if there was a difference in attentional functioning and static postural control among groups of Comparison, Coper and CAI participants and assess the relationship between them within each of the groups. Recruited participants performed single-limb balance trials and completed the CNS Vital Signs (CNSVS) computer-based assessment to assess their attentional function. Center …

Sandbagging On The Immediate Post-Concussion Assessment And Cognitive Testing (Impact) In A High School Athlete Population, Kathryn L. Higgins, Robert L. Denny, Arthur C. Maerlender
Center for Brain, Biology, and Behavior: Faculty Publications
The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called “sandbagging,” in order to return to their baseline cognitive scores, and thus to play, more quickly. This research examines ImPACT baseline scores when high school athletes were asked to attempt to “sandbag,” and compares those scores with scores …

High levels of endurance training have been associated with potentially negative health outcomes and addictive-like symptoms such as exercise in the presence of injury and higher levels of impulsivity. This pilot study examined the relationships among self-report measures of addictive symptoms related to exercise and behavioral and neural measures of impulsivity in endurance runners. We hypothesized endurance runners would have increased preference for immediate rewards and greater activation of cognitive control regions when making decisions involving delayed rewards. Twenty endurance runners (at least 20 miles/week) were recruited to undergo measures of self-report exercise addiction symptoms, impulsive decision-making (delay discounting) and …

Lateral hypothalamic area (LHA) local field potentials (LFPs) were recorded in a Prader–Willi patient undergoing deep brain stimulation (DBS) for obesity. During hunger, exposure to food-related cues induced an increase in beta/ low-gamma activity. In contrast, recordings during satiety were marked by prominent alpha rhythms. Based on these findings, we have delivered alphafrequency DBS prior to and during food intake. Despite reporting an early sensation of fullness, the patient continued to crave food. This suggests that the pattern of activity in LHA may indicate hunger/satiety states in humans but attest to the complexity of conducting neuromodulation studies in obesity.

Developmental Disabilities And Family Dynamics, Meghan Murray

Typically developing (TD) siblings of children with an Intellectual or Developmental Disability (IDD) are among those most influenced by their sibling’s diagnosis. Factors such as increased family stress, lack of family communication, and negative sibling perception can play a role in leading to internalizing and externalizing problems from the TD child. A limit to the existing sibling relationship literature is that the relationships in families with a child with IDD have only been collected via self-report measures through which respondents have been found to fake their responses to avoid being perceived in certain ways. Conversely, implicit measures, such as the …

Loss of control –inflight (LOC-I) has historically represented the largest category of commercial aviation fatal accidents. A review of worldwide transport airplane accidents (2001-2010) indicated that loss of airplane state awareness (ASA) was responsible for the majority of the LOC-I fatality rate. The Commercial Aviation Safety Team (CAST) ASA study identified12 major themes that were indicated across the ASA accident and incident events. One of the themes was crew distractionorineffective attention management, which was found to be involved in all 18 events including flight crew channelized attention, startle/surprise, diverted attention, and/or confirmation bias. Safety Enhancement(SE)-211, “Training for Attention Management” was …

International Symposium on Aviation Psychology - 2017
A Commercial Aviation Safety Team (CAST) study of 18 worldwide loss-of-control accidents and incidents determined that the lack of external visual references was associated with aflight crew’s loss of attitude awareness or energy state awareness in 17 of these events. Therefore, CAST recommended development and implementation of virtual day-Visual Meteorological Condition (VMC)display systems, such as synthetic vision systems, whichcan promoteflight crew attitude awareness similar to a day-VMC environment. This paper describes the results of a high-fidelity, large transport aircraft simulation experimentthatevaluatedvirtual day-VMC displays and a “background attitude indicator” concept as an aid to pilots in recovery from unusual attitudes.

The FAA is developing a standard set of colors for use inair traffic control (ATC) displays.The set will be defined in terms ofCIE Yu'v'values, corresponding sRGB values, and color names. A significant complication is that the ATC controller population includes people who havecolor-vision deficiencies (CVDs). We have written a softwaretool to assist the FAA inselecting and testing a suitable set of colors. It accepts a set of Yu'v'values as input and: (1) Draws graphics and calculates color-related figures of merit to predict whether the set will be acceptable for color-normal and CVD …

We have implemented an integrated system, called Computational Situation Awareness (CSA), into a prototype control station to coordinate dynamic task sharing and allow UxV operators to be quickly brought up to speed with sufficient situation awareness to effectively understand and handle new tasking. Within CSAwe have implemented a real-time workload model for estimating workload across a user’s visual, tactile, and cognitive resources. This workload estimate enables the system to recognize when tasks should be handed off and to whom they should be handed. By tracking user tasks, user workload, and system state, the system builds an understanding of the team’s …

Aptitude testing and “screening” at the FAA Academy have been viewed as keys to reducing field ATCS training attrition. To what extent have ATCS field training attrition rates changed over time with testing and screening? Historical data on training outcomes were extracted from FAA reports and other documented sources for controllers hired in five non-overlapping cohorts spanning 50 years. Academy Attrition Rateaveraged 26% (SD=18%) over the 50 yearsand across options, compared to 25% (SD=4%)in field training. LowerField Training Attrition Ratescoincided with no screening (22%, 1968– 1970) and intensive screening (19%, 1986–1992). Elimination of screening did not result …

NSSI affects many young adults and is associated with suicidal ideation, as well as numerous mental health disorders and other psychological variables. There were a total of 59 participants that participated in this study from an undergraduate college sample who endorsed self-injuring. An online platform for research was used to recruit participants and provide them with the online survey link. Self-injuring more than one bodily location may result in feeling more stigma than individuals who self-injure one bodily location. Self-stigma and self-injuring multiple bodily locations both significantly predicted suicidal ideation, but gender and social support did not predict suicidal ideation. …
