BACKGROUND: In 2013 the U.S. Army began developing physical tests to predict a recruit’s ability to perform the critical physically demanding tasks (CPDTs) of combat arms jobs not previously open to women. OBJECTIVE: To revalidate 15 CPDTs chosen by subject matter experts (SMEs) and researchers through questionnaires pertaining to task performance frequency, perceived importance, and performance expectations. METHOD: Web-administered job analysis questionnaires were completed by 2,090 soldiers. Seventy-three percent ranged between 25–38 years of age, 66%were staff sergeants or above, and 73%were in service for 7 + years. RESULTS: Overall, the nine SME-endorsed CPDTs were conducted more frequently and rated as more important than the six tasks identified by researchers. Foot march, dragging a casualty to safety, and connecting a tow bar (vehicle transport) were identified as the combined most important, most frequently performed and highly expected CPDTs to be performed. The canonical correlation between task performance frequencies and ratings of task importance across all 15 CPDTs was 0.82 (p <  0.001). Expectations of task completion were strongly associated with more frequent task performance (Cramer’s Vs ranged 0.22 to 0.71; all p‘s <  0.001), but not task importance (only four CPDTs at p <  0.05). CONCLUSION: This study revalidates the value of CPDTs chosen by SMEs and researchers. Soldier readiness should reflect tasks identified by incumbents as important to success (e.g., evacuating a casualty) be trained more often, whereas others classified as frequently performed, but less important (e.g., filling sandbags), be deemphasized while ensuring that standards are met.

The effects of success and failure on task performance, and attributions about performance, were compared for high and low instrumental college women. For the high instrumental group, success facilitated task performance, whereas failure had no debilitating effect; for the low instrumental group, success had no effect on subsequent performance, whereas failure interfered with it. High instrumental women attributed their success primarily to internal factors and their failures to external tactors (the “egotistical” attribution profile), whereas low instrumentar women revealed the opposite profile. The gender-appropriateness of the task had little effect on performance or attribution. Four potential mediators of these differences were investigated: self-esteem, perceived ability, expectancy of success, and attainment value. High-instrumental women's higher perceived ability and performance expectations accounted for their superior task performance, but none of the four mediators accounted for the relationship of instrumentality to attributions.

Despite the value of community health worker programs, such as Promotores de Salud, for addressing health disparities in the Latino community, little consensus has been reached to formally define the unique roles and duties associated with the job, thereby creating unique job training challenges. Understanding the job tasks and worker attributes central to this work is a critical first step for developing the training and evaluation systems of promotores programs. Here, we present the process and findings of a job analysis conducted for promotores working for Planned Parenthood. We employed a systematic approach, the combination job analysis method, to define the job in terms of its work and worker requirements, identifying key job tasks, as well as the worker attributes necessary to effectively perform them. Our results suggest that the promotores’ job encompasses a broad range of activities and requires an equally broad range of personal characteristics to perform. These results played an important role in the development of our training and evaluation protocols. In this article, we introduce the technique of job analysis, provide an overview of the results from our own application of this technique, and discuss how these findings can be used to inform a training and performance evaluation system. This article provides a template for other organizations implementing similar community health worker programs and illustrates the value of conducting a job analysis for clarifying job roles, developing and evaluating job training materials, and selecting qualified job candidates.

Abstract. Building on previous research which suggests that females are at a disadvantage when working with computers, the current paper investigates possible explanations. We used the cognitive-motivational process model ( Vollmeyer & Rheinberg, 1999 , 2000 ) to explore if motivation can account for the performance differences between male and female students. The model assumes that initial motivation affects strategies and motivation during learning which then influence performance. Male and female students from an introductory statistics class (N = 40), had to solve four statistics tasks with SPSS in 30 minutes. Measurements included initial motivation, functional state (i.e., flow) during task performance, navigation style, and task performance. Results show that males outperform females in terms of time needed for task completion and performance level. Male students displayed more solution-oriented navigation traces than female students. In a tentative exploratory path model, flow-experience and navigation style could be identified as mediating variables. The findings are interpreted in terms of a more effective use of trial-and-error strategies and a preference for tinkering behavior by males.

Heavy physical requirements characterize a large number of military occupational specialties (MOSs). Current efforts at reducing some of these physical requirements stem from concerns with health and safety, the need to conserve soldier strength and endurance for other battlefield tasks, and the need to optimize personnel utilization. This paper describes an ongoing feasibility study aimed at identifying and attempting to reduce physical demands in five MOSs. Three data-collection phases involve (a) review of publications describing occupational tasks, (b) structured interviews with subject matter experts (SMEs), and (c) filming the most physically demanding tasks. The fourth phase involves use of SMEs and ergonomists to identify specific redesign solutions. An illustrative example is provided. This technique coupled with others (job selection and physical training) can enhance military operational capability by reducing physical requirements.

End-to-end latency in remote-rendering systems can reduce user task performance. This notably includes aiming tasks on game streaming services, which are presently below the standards of competitive first-person desktop gaming. We evaluate the latency-induced penalty on task completion time in a controlled environment and show that it can be significantly mitigated by adopting and modifying image and simulation-warping techniques from virtual reality, eliminating up to 80% of the penalty from 80 ms of added latency. This has potential to enable remote rendering for esports and increase the effectiveness of remote-rendered content creation and robotic teleoperation. We provide full experimental methodology, analysis, implementation details, and source code.

Objective. Stress-reducing therapies help maintain cognitive performance during stress. Aromatherapy is popular for stress reduction, but its effectiveness and mechanism are unclear. This study examined stress-reducing effects of aromatherapy on cognitive function using the go/no-go (GNG) task performance and event related potentials (ERP) components sensitive to stress. The study also assessed the importance of expectancy in aromatherapy actions.Methods. 81 adults were randomized to 3 aroma groups (active experimental, detectable, and undetectable placebo) and 2 prime subgroups (prime suggesting stress-reducing aroma effects or no-prime). GNG performance, ERPs, subjective expected aroma effects, and stress ratings were assessed at baseline and poststress.Results. No specific aroma effects on stress or cognition were observed. However, regardless of experienced aroma, people receiving a prime displayed faster poststress median reaction times than those receiving no prime. A significant interaction for N200 amplitude indicated divergent ERP patterns between baseline and poststress for go and no-go stimuli depending on the prime subgroup. Furthermore, trends for beneficial prime effects were shown on poststress no-go N200/P300 latencies and N200 amplitude.Conclusion. While there were no aroma-specific effects on stress or cognition, these results highlight the role of expectancy for poststress response inhibition and attention.
