7 hyperactive children in a pilot study, and 15 hyperactive and 15 non-hyperactive control children in a later study, were assessed for salivation to lemon juice stimulation, reactive inhibition on an audio-vigilance task, and visual-motor maze errors. Hyperactive children were tested under stimulant drug and nondrug conditions and nonhyperactive children twice under nondrug conditions. Pilot study hyperactive children displayed significantly fewer maze errors and somewhat greater salivation and lesser reactive inhibition levels under the drug than the nondrug conditions. Follow-up study control children did not differ significantly between test occasions on any measure, while the hyperactive children displayed significantly fewer maze errors, mote salivation, and less reactive inhibition under the stimulant drug, indicating significant decreases in extraversion after the stimulant drug.

Abstract Objective The FEAr pilot study was conducted to evaluate the construct validity of an instrument that measures self-reported fatigue levels among air medics (the Flight Risk Assessment [FRA] measure). Data Selection The population of interest, flight medics, is highly specialized and relatively small. As a result, non-probability, convenience sampling was used (N = 27). The participants were recruited from one air medical company with bases located across ten western states. Medics took two measures, the FRA and the PVT, three times a day, for three days. Data Synthesis To establish construct validity, scores on the FRA were compared to scores on the Psychomotor Vigilance Task (PVT), which is a widely used and validated measure to detect fatigue in field settings. The results of the study indicate that a total of five questions on the FRA was significantly and moderately correlated with the PVT efficiency score (r = -.49, p = .01). The mean reaction time was also significantly correlated with the total FRA score (r = .59, p = .001). Notably, perceived fitness for duty was poorly correlated with fatigue levels as measured by the FRA (r < .01). Conclusions The results of this study contribute to a very limited body of research on fatigue among air medical providers. Specifically, the study contributes to the knowledge about the construct validity of the Flight Risk Assessment, which can be used to evaluate fatigue among air medics. Further analysis can assist in determining appropriate cutoff scores to inform time-out policies for medics.

Methods to enhance the ergogenic effects of music are of interest to athletes of all abilities. The aim of this pilot study was to investigate the ergogenic effects of two commercially available methods of music augmentation: auditory beats and vibrotactile stimulation. Six male and five female cyclists/triathletes cycled for 7 minutes at three different intensities: a rate of perceived exertion (RPE) of 11 (“light”), RPE of 15 (“hard”), and a 7-minute time-trial. Before each 7-minute bout of cycling, participants listened to 10 minutes of self-selected music (MUS), or the same music with the addition of either isochronic auditory beats (ABS) or vibrotactile stimulation via SUBPACTM (VIB). MUS, ABS and VIB trials were performed in a randomized order. Power output was measured during cycling and felt arousal and feeling scores were recorded at timepoints throughout the protocol. The results found the augmented MUS interventions did not influence power output with no significant main effect of trial (p = 0.44, η2 = 0.09) or trial × cycling intensity interaction (p = 0.11, η2 = 0.20). Similarly, both felt arousal and feeling scores were unchanged between the MUS, ABS, and VIB trials (p &gt; 0.05). In conclusion, this pilot study indicated an ineffectiveness of the ABS and VIB to affect subsequent 7-min cycling performance compared to self-selected MUS alone.

Purpose This pilot study explored the effectiveness of an early storybook reading (ESR) intervention for parents with babies with hearing loss (HL) for improving (a) parents' book selection skills, (b) parent–child eye contact, and (c) parent–child turn-taking. Advancing research into ESR, this study examined whether the benefits from an ESR intervention reported for babies without HL were also observed in babies with HL. Method Four mother–baby dyads participated in a multiple baseline single-case experimental design across behaviors. Treatment effects for parents' book selection skills, parent–child eye contact, and parent–child turn-taking were examined using visual analysis and Tau-U analysis. Results Statistically significant increases, with large to very large effect sizes, were observed for all 4 participants for parent–child eye contact and parent–child turn-taking. Limited improvements with ceiling effects were observed for parents' book selection skills. Conclusion The findings provide preliminary evidence for the effectiveness of an ESR intervention for babies with HL for promoting parent–child interactions through eye contact and turn-taking.
