Psychological Hardiness Predicts Success in US Army Special Forces Candidates

Military ‘Special Forces’ represent a high‐reliability occupation, where stress levels are often intense and failure can be costly. Selection for such jobs should pay careful attention to psychological factors associated with resiliency under stress. In the present study, US Army Special Forces candidates (N=1138) were assessed for psychological hardiness using a short form of the Dispositional Resilience Scale, and these scores were then applied to predict successful completion of the course. Independent sample t‐tests and logistic regression analyses confirmed that Special Forces course graduates are significantly higher in psychological hardiness, as compared to non‐graduates. Psychological hardiness appears to be an important individual characteristic associated with stress tolerance and successful performance in highly demanding occupations.     

The discrimination of temporal fine structure in call-like harmonic sounds by birds

Thresholds for discriminating changes in the temporal fine structure of call-like, harmonic sounds were measured in zebra finches (Taeniopygia guttata) and budgerigars (Melopsittacus undulatus). Birds could detect changes in periods as short as 1.225 ms at near 100% accuracy even when spectral and envelope cues were identical, as in time-reversed stimuli. Humans performed poorly on such stimuli, paralleling results from previous studies. Bird thresholds were in the range of those reported in neurophysiological studies of the songbird high vocal center (HVC) to temporally modified conspecific songs. Taken together, these results show that birds can hear differences in temporal fine structure in their natural vocalizations that go beyond human capabilities, but whether these abilities have communicative relevance remains to be seen.     

Coping with recruiter stress: Hardiness,performance and well-being in US Army recruiters

ABSTRACT

Recruiting for military service can be a highly stressful job, but it is one that is essential for success in the all-volunteer force. Military recruiters face a number of job stressors, including pressure to meet monthly production quotas, long work hours and time away from family. They also work in relative isolation, with limited work social support networks. These factors make recruiters vulnerable to burnout and early attrition. The present study examines psychological hardiness and active, problem focused coping as potential stress resilience resources in US Army recruiters. In a stratified random sample of N = 817 recruiters, hardiness was found to predict supervisor-rated performance and psychological well-being. Hardiness also interacted with problem focused coping to predict psychological well-being, suggesting a mediating role for coping. These results can be applied to help improve policy for selecting and training military recruiters.
