The Cognitive Demands of Gait Retraining in Runners: An EEG Study

Abstract

High impact forces during running have been associated with tibial stress injuries. Previous research has demonstrated increasing step rate will decrease impact forces during running. However, no research has determined the cognitive demand of gait retraining. The primary purpose was to determine the cognitive demand and effectiveness of field-based gait retraining. We hypothesized that in-field gait retraining would alter running mechanics without increasing cognitive workload as measured by EEG following learning. Runners with a history of tibial injury completed a gait retraining protocol which included a baseline run, retraining phase, practice phase, and re-assessment following retraining protocol. Results demonstrated an increase in the theta, beta, and gamma power within prefrontal cortex during new learning and corresponding return to baseline following skill acquisition and changes across alpha, beta, gamma, mu, and theta in the motor cortex (p < .05). In the midline superior parietal cortex, spectral power was greater for theta activity during new learning with a corresponding alpha suppression. Overall, the results demonstrated the use of EEG as an effective tool to measure cognitive demand for implicit motor learning and the effectiveness of in-field gait retraining.     

Independently Licensed Counselors' Work Values

Prospective clinical mental health counseling students need to know if their work values align with those of independently licensed counselors before investing their time and accumulating debt. Analyzing the work values of 463 independently licensed counselors in the United States, we found 89% expressing social (altruistic) work values and 22% expressing intrinsic work values. Independently licensed counselors want to help clients become fully functioning and self-actualized by maintaining unconditional positive regard, being congruent, and providing empathy. Clarifying these work values and their interaction can help prospective and current clinical mental health counseling students determine their future job role.     

Climate action now: How to fuel a social movement

Our research develops a framework that explores how to fuel the climate movement by accelerating grassroots, community-based climate action. Drawing on insights from consumer psychology, our framework identifies the psychological mechanisms that encourage and motivate people, both individually and collectively, to take climate action, thereby contributing to our understanding of how to advance social action and propel a social movement. Our climate action framework builds on: (1) individuals we describe as climate upstanders who rise up to take climate action with like-minded others, and (2) communities of climate upstanders who engage in collective action aimed at addressing the climate crisis. Our framework expands the field of consumer psychology by redefining the role of consumers to include the practice of social action and broadening the study of consumers to include collective, community-based action. We call on consumer psychologists to research individual and collective consumer practices related to social action and contribute to making social good central to the study of consumer psychology.     

Health Risk Behaviors and Their Relationships to Health Care Utilization Among Veterans Receiving Primary Medical Care

This paper reports the findings of a behavioral health risk screening form and examines the interrelationships among behavioral risk factors and health care utilization. Participants were 1,000 veterans who completed a brief self-report questionnaire assessing affective distress and behavioral health risk factors while they waited to see their primary care provider. Participants reported a mean level of affective distress in the mild range on a scale of 0 to 20 (M = 6.4, SD = 4.95), and 22.4% reported moderate or high levels of affective distress. Fifty percent of the sample denied alcohol use; 5% of the men and none of the women reported a pattern of use that met established criteria for at-risk drinking. Twenty-six percent of the sample reported current tobacco use, 45% acknowledged concerns about diet and/or weight, and 54% reported concern about pain. These factors were largely significantly intercorrelated and several were related to indices of health care utilization. It was concluded that veterans receiving health care in primary care settings report significant levels of affective distress and other health risk behaviors and that the presence of these factors is associated with increased use of the health care system. These data encourage increased efforts to identify these factors and to develop behavior change interventions.     

Mixed Messages: Co-Worker Responses to the Pregnant Employee

American organizations have been actively implementing work and family programs to meet employees' family demands. However, few comprehensive efforts to include the specific needs of pregnant employees into work and family programs have been taken. According to women who are or have been pregnant while employed, organizations must provide greater understanding and flexibility to pregnant employees. Women report mixed messages received from both co-workers and company policies. Based on the reports of pregnant women, recommendations are given which will guide co-workers on maintaining appropriate interactions with pregnant peers and help companies to better incorporate the concerns of pregnant employees into work and family initiatives.     

The psychological benefit of future vividness in goal persistence: An illustrative case of the class of 2020 before & during COVID-19

Graduating during COVID-19, the Class of 2020 had difficulty pursuing their future goals. This research examined the likelihood of academic and career goal change early in the pandemic, disparities in persistence by socioeconomic status (SES), and how psychological resources mitigated goal change during the early stages of the pandemic. This 4-year study surveyed students in the Class of 2020 eight times from their first week in college (Fall 2016) to their last semester before graduation (Spring 2020; N = 115; 20% below middle SES, 80% middle SES or above). Even in the first weeks of COVID-19, a quarter of students changed goals. Lower SES students were less likely to persist in their post-graduation plans. Nevertheless, students who entered college with a vivid image of their future were more likely to have secured a graduate school or job prospect prior to COVID-19, and, in turn, were less likely to change goals.     

Rapid judgements in assessing verbal and nonverbal cues: their potential for deception researchers and lie detection

In the present study it was investigated to what extent observers (i) could make rapid yet reliable and valid judgements of the frequency of verbal and nonverbal behaviours of interviewees (liars and truth tellers) and (ii) detect deceit after making these rapid judgements. Five observers watched 52 videoclips of 26 liars and 26 truth tellers. The findings revealed that rapid judgements were reliable and valid. They also revealed that observers were able to detect truths and lies well above the level of chance after making these rapid judgements (74% accuracy rate was found). The implications of these findings for deception researchers and lie detection are discussed. Copyright © 2004 John Wiley & Sons, Ltd.
