Item Examining the time course of post collaborative benefits across word lists and prose passages(Springer Science and Business Media LLC, 2024-07) Wei, Yunfeng; Charbonneau, Brooke Z.; Meade, Michelle L.; Hutchison, Keith A.In the current study, we investigated how long the effects of one single collaboration session continue to influence individual memory. Participants learned categorized word lists and prose passages individually, and then they were instructed to recall learned materials either collaboratively or individually. Following initial recall, participants completed an individual recall test after a delay of 5 min, 48 h, or 1 week. On the initial recall test, we found that collaboration reduced recall of correct items on both word lists and prose passages (collaborative inhibition), and that collaboration reduced false recall on both word lists and prose passages (error correction). However, on the subsequent individual memory test after a delay, the pattern of post collaborative effects differed across veridical and false recall. For both word lists and prose passages, post collaborative benefits on correct recall lasted 1 week. However, there were no lasting effects of error correction on subsequent false recall. These results suggest that the time course of post collaborative benefits can be long lasting, but they are selective to veridical recall. The results are explained by theories of reexposure and error correction.Item Perceived discrimination, political efficacy, and political participation in American Indian adults(Frontiers Media SA, 2024-03) Wood, Zachary J.; John-Henderson, Neha A.Introduction: Psychological factors linked to political participation are largely understudied in American Indians. Prior work notes relatively low levels of participation compared to other racial and ethnic groups and suggests that identification with being American Indian is linked to overall levels of civic engagement in part through perceptions of group discrimination. Methods: In the current work, in a sample of 727 American Indian adults, we created two groups: Group 1 (N = 398) reported perceived discrimination related to race, and Group 2 (N = 329) reported perceived discrimination not related to race or ethnicity. We investigated the relationships between individual experiences of everyday discrimination related to race, levels of political efficacy, and political participation (Group 1), and individual experiences of everyday discrimination not related to race or ethnicity, political efficacy, and political participation (Group 2). Results: We found that greater experiences of everyday discrimination related to race was associated with higher levels of political participation through increased levels of internal and collective efficacy. In contrast, greater experiences of everyday discrimination related to race was associated with higher levels of political participation through lower external political efficacy. For Group 2, we found that greater experiences of everyday discrimination not related to race or ethnicity was not directly associated with political participation, but mediation analyses revealed a relationship with lower levels of political participation through decreased internal and collective efficacy. The indirect effect through external political efficacy was not significant. Discussion: Given low levels of American Indian political participation, political efficacy could be a target for interventions aiming to increase participation in the political system.Item Profiles of historical loss and childhood trauma as predictors of mental and cardiometabolic health in American Indian adults(Elsevier BV, 2023-12) John-Henderson, Neha A.; Ginty, Annie T.Cardiometabolic disease and mental health conditions are two major contributors to persistent inequities in health and life expectancy for American Indian adults. The atrocities associated with European colonization are linked to intergenerational psychological and emotional wounding (i.e., historical trauma) and high incidence of childhood trauma. Prior work has examined the independent relationships of childhood trauma and thoughts about historical loss with cardiometabolic and mental health in American Indians. In the current work, we used a data-driven approach to identify profiles of childhood trauma and frequency of thoughts about historical loss, and then examined how these profiles related to cardiometabolic and mental health in a sample of American Indian adults from across the United States (N = 727). We found that a profile characterized by high levels of childhood trauma and high frequency of thoughts about historical losses was associated with the greatest risk for mental health conditions. The profile characterized by the highest levels of childhood trauma and by moderate frequency of thoughts about historical losses was associated with the largest risk of cardiometabolic conditions. The findings represent an important first step towards understanding how childhood trauma and thoughts about historical loss may simultaneously inform enduring inequities in American Indian health.Item Fast, Accurate, But Sometimes Too-Compelling Support: The Impact of Imperfectly Automated Cues in an Augmented-Reality Head-Mounted Display on Visual Search Performance(Institute of Electrical and Electronics Engineers, 2023-01) Warden, Amelia C.; Wickens, Christopher D.; Rehberg, Daniel; Ortega, Francisco R.; Clegg, Benjamin A.While the visual search for targets in a complex scene might benefit from using augmented-reality (AR) head-mounted display (HMD) technologies by helping to efficiently direct human attention, imperfectly reliable automation support could manifest in occasional errors. The current study examined the effectiveness of different HMD cues that might support visual search performance and their respective consequences following automation errors. A total of 56 participants searched a three-dimensional environment containing 48 objects in a room, in order to locate a target object that was viewed prior to each trial. They searched either unaided or assisted by one of the three HMD types of cues: an arrow pointing to the target, a plan-view minimap highlighting the target, and a constantly visible icon depicting the appearance of the target object. The cue was incorrect in 17% of the trials for one group of participants and 100% correct for the second group. Through both analysis and modeling of both search speed and accuracy, the results indicated that the arrow and minimap cues depicting location information were more effective than the icon cue depicting visual appearance, both overall, and when the cue was correct. However, there was a tradeoff on the infrequent occasions when the cue erred. The most effective AR-based cue led to a greater automation bias in which the cue was more often blindly followed without careful examination of the raw images. The results speak to the benefits of AR and the need to examine potential costs when AR-conveyed information may be incorrect because of imperfectly reliable systems.Item How history trails and set size influence detection of hostile intentions(Springer Science and Business Media LLC, 2022-05) Patton, Colleen E.; Wickens, Christopher D.; Clegg, Benjamin A.; Noble, Kayla M.; Smith, C. A. P.Previous research suggests people struggle to detect a series of movements that might imply hostile intentions of a vessel, yet this ability is crucial in many real world Naval scenarios. To investigate possible mechanisms for improving performance, participants engaged in a simple, simulated ship movement task. One of two hostile behaviors were present in one of the vessels: Shadowing—mirroring the participant’s vessel’s movements; and Hunting—closing in on the participant’s vessel. In the first experiment, history trails, showing the previous nine positions of each ship connected by a line, were introduced as a potential diagnostic aid. In a second experiment, the number of computer-controlled ships on the screen also varied. Smaller set size improved detection performance. History trails also consistently improved detection performance for both behaviors, although still falling well short of optimal, even with the smaller set size. These findings suggest that working memory plays a critical role in performance on this dynamic decision making task, and the constraints of working memory capacity can be decreased through a simple visual aid and an overall reduction in the number of objects being tracked. The implications for the detection of hostile intentions are discussed.Item Supporting detection of hostile intentions: automated assistance in a dynamic decision-making context(Springer Science and Business Media LLC, 2023-11) Patton, Colleen E.; Wickens, Christopher D.; Smith, C. A. P.; Noble, Kayla M.; Clegg, Benjamin A.In a dynamic decision-making task simulating basic ship movements, participants attempted, through a series of actions, to elicit and identify which one of six other ships was exhibiting either of two hostile behaviors. A high-performing, although imperfect, automated attention aid was introduced. It visually highlighted the ship categorized by an algorithm as the most likely to be hostile. Half of participants also received automation transparency in the form of a statement about why the hostile ship was highlighted. Results indicated that while the aid’s advice was often complied with and hence led to higher accuracy with a shorter response time, detection was still suboptimal. Additionally, transparency had limited impacts on all aspects of performance. Implications for detection of hostile intentions and the challenges of supporting dynamic decision making are discussed.Item Association of racism and substance use treatment with belief in the myth of an American Indian/Alaska Native biological vulnerability to alcohol problems(American Psychological Association, 2023-06) Gonzalez, Vivian M.; Skewes, Monica C.Objectives: Belief in an American Indian/Alaska Native (AIAN) specific biological vulnerability (BV) to alcohol problems is associated with worse alcohol outcomes among AIANs. Despite a notable lack of evidence that biogenetic factors play a greater role in the development of alcohol problems among AIANs than other groups, many people still believe this myth. Consistent with theory and evidence that greater experiences with discrimination leads to the internalization of stereotypes and oppression, we hypothesized that greater perceived racial discrimination (racism) would be associated with greater BV belief, but that having a stronger ethnic identity would weaken this association. We also examined whether previous substance use treatment as well as participation in Alcoholics Anonymous (AA) or Narcotics Anonymous (NA) was associated with BV belief. Method: Participants were 198 reservation-dwelling AI adults with a substance use problem who completed a survey as part of a larger community-based participatory study. Results: A multiple regression analysis revealed that greater systemic racism was associated with greater belief in a BV; this association was not moderated by ethnic identity. Greater interpersonal racism was also associated with greater BV belief—but only among those low in ethnic identity. A regression analysis revealed that previous treatment, AA, and NA participation were not associated with BV belief. Conclusions: Greater systemic and interpersonal racism were associated with belief in a BV, and greater ethnic identity buffered the association between interpersonal racism and BV belief. This suggests that both combatting racism and fostering positive ethnic identity may help to lessen BV belief.

In order to develop effective vaccine uptake interventions, we need to understand the extent to which vaccine hesitancy fluctuates and identify factors associated with both between- and within-person differences in vaccine hesitancy. The goals of the current study were to assess the extent to which COVID-19 vaccine hesitancy varied at an individual level across time and to determine whether disgust sensitivity and germ aversion were associated with between- and within-person differences in COVID-19 vaccine hesitancy. A national sample of U.S. adults (N = 1025; 516 woman; Mage = 46.34 years, SDage = 16.56, range: 18 to 85 years; 72.6 % White) completed six weekly online surveys (March 20 – May 3, 2020). Between-person mean COVID-19 vaccine hesitancy rates were relatively stable across the six-week period (range: 38–42 %). However, there was considerable within-person variability in COVID-19 vaccine hesitancy. Approximately, 40 % of the sample changed their vaccine hesitancy at least once during the six weeks. There was a significant between-person effect for disgust sensitivity, such that greater disgust sensitivity was associated with a lower likelihood of COVID-19 vaccine hesitance. There was also a significant within-person effect for germ aversion. Participants who experienced greater germ aversion for a given week relative to their own six week average were less likely to be COVID-19 vaccine hesitant that week relative to their own six-week average. This study provides important information on rapidly changing individual variability in COVID-19 vaccine hesitancy on a weekly basis, which should be taken into consideration with any efforts to decrease vaccine hesitancy and increase vaccine uptake. Further, these findings identify-two psychological factors (disgust sensitivity and germ aversion) with malleable components that could be leveraged in developing vaccine uptake interventions.Item Development and Feasibility Pilot Study of Indigenous Recovery Planning: A Community-Engaged Approach to Addressing Substance Use in a Native Community(SAGE Publications, 2023-02) Skewes, Monica C.; Gonzalez, Vivian M.; Gameon, Julie A.; Ricker, Adriann; Martell, Shannon; Reum, Martel; Holder, ShannonAlthough Native (American Indian [AI] and Alaska Native [AN]) populations have high rates of abstinence from alcohol, health problems associated with substance use remain a pressing concern in many AI/AN communities. As part of a longstanding community-based participatory research project involving 5 years of relationship building and three preliminary studies, our team of academic and community coresearchers developed a culturally grounded intervention to facilitate recovery from substance use disorders among tribal members from a rural AI reservation. Our Indigenous Recovery Planning (IRP) intervention consists of six weekly sessions and is designed to provide inroads to existing resources in the community, affirm and enhance Native identity, address culturally relevant risk factors, and build on strengths. Results from a feasibility pilot study (N = 15) suggest that IRP is feasible to implement and acceptable to the community. Although there was insufficient statistical power to conduct hypothesis testing, there were changes between pretest and posttest scores in the expected directions. Future directions and limitations of this research are discussed.Item Infant negativity moderates trajectories of maternal emotion across pregnancy and the peripartum period(Elsevier BV, 2023-01) Brooker, Rebecca J.; Mistry-Patel, Sejal; Kiel, Elizabeth J.; Liu, Shuling; Van Lieshout, Ryan J.; Schmidt, Louis A.; John-Henderson, NehaBackground. Although the effects of maternal behavior on the development of child emotion characteristics is relatively well-established, effects of infant characteristics on maternal emotion development are less well known. This gap in knowledge persists despite repeated calls for including child-to-mother effects in studies of emotion. We tested the theory-based postulate that infant temperamental negativity moderates longitudinal trajectories of mothers’ perinatal symptoms of anxiety and depression. Method. Participants were 92 pregnant community women who enrolled in a longitudinal study of maternal mental health; symptoms of anxiety and depression were assessed during the second and third trimesters of pregnancy and again at infant age 4 months. A multimethod assessment of infants’ temperament-based negative reactivity was conducted at infant age 4 months. Results. Maternal symptoms of anxiety showed smaller postnatal declines when levels of infant negativity were high. Mother rated and observed infant negative reactivity was related to smaller postnatal declines in maternal anxiety, while infant negative reactivity, at the level of neuroendocrine function, was largely unrelated to longitudinal changes in maternal anxiety symptoms. Infant negativity was related to early levels, but largely unrelated to trajectories of maternal symptoms of depression. Limitations. Limitations of this work include a relatively small and low-risk sample size, the inability to isolate environmental effects, and a nonexperimental design that precludes causal inference. Conclusions. Findings suggest that levels of infant negativity are associated with differences in the degree of change in maternal anxiety symptoms across the perinatal period.
