Although the 14th Amendment of the U.S. Constitution grants American citizenship to any person born or naturalized in this country, subjective perceptions of who belongs in the country are driven by default assumptions that the prototypical American is White. This belief that Whites are somehow more American than members of other ethnic groups lies in sharp contrast to the widespread endorsement of multiculturalism in everyday life. Two studies provide evidence that these race-based beliefs about the prototypical American can produce discriminatory behavior against ethnic minorities in domains where patriotism is relevant, but not in domains where patriotism is irrelevant. Study 1 demonstrated that the more participants believe that the prototypical American is White, the less willing they are to hire highly qualified Asian Americans in national security jobs where patriotism is essential. Additionally, this effect was partially mediated by doubts about Asian Americans’ loyalty to thee country. Study 2 replicated and extended these findings by demonstrating that the more participants believe that the prototypical American is White, the less willing they are to hire highly qualified Asian Americans in national security jobs, but not in private business jobs where patriotism is irrelevant. Together, these studies demonstrate how race-based beliefs about the prototypical American can lead to discriminatory behavior against ethnic minorities, particularly in domains where national loyalty is important.

Indiana University-Purdue University Indianapolis (IUPUI) / Fibromyalgia Syndrome (FMS) is a chronic, painful rheumatic condition characterized by recurrent musculoskeletal pain, fatigue, and nonrestorative sleep, for which there is currently no biological marker. People who suffer from fibromyalgia are extremely susceptible to the effects of psychological stressors which may in turn exacerbate the symptoms of the disease. As unrelenting pain is the main symptom of fibromyalgia, it follows that patients would experience personal losses and changes in their self-schemas or the way in which they view themselves as a result. This study was particularly focused on identifying the enmeshment of self-schemas and pain-schemas, and the extent to which women with fibromyalgia experience pain and self-schema enmeshment (PSSE). Additionally, this study sought to determine the utility of using the Implicit Association Test as a measure of PSSE. The present study compared FMS patients to a group of diabetes patients on several measures of schema enmeshment, including the IAT. It was hypothesized that the two disease groups would differ significantly on the level of PSSE indicated by the IAT, and the two disease groups would not differ on enmeshment with illness indicated by the IAT. Additionally it was hypothesized that the IAT would be correlated with explicit measures of PSSE. Results did not support either of these hypotheses; however the sample size and statistical power necessary to test these hypotheses was severely lacking and thus they could not be evaluated in an appropriate manner. Results did not support the hypothesis that the IAT would be highly correlated with the explicit measures of PSSE. Based on these results and the existing literature, it is still somewhat unclear as to whether or not the IAT would be an acceptable/feasible tool in assessing PSSE in fibromyalgia patients.

I investigated the presence, utility, and emergence of tacit knowledge in 9 study participants who used assistive-augmentative technology. I conducted phenomenologic interviews, audio-taping, and transcribed the interview with the written consent of the participants. Sixteen highly trained experts critiqued the final product of the interviews and answered a 25-question survey instrument. Non-parametric statistical processes were chosen to conduct inferential hypotheses testing. Wilcoxon - Mann Whitney U tests and Kruskal - Wallis One-Way ANOVA (alpha level of 0.05) were used for questions 1-10, and a 2 x R (R = 3 or 4) contingency table and Fisher's Exact Chi-Square were used for questions 11- 25. The responses to survey questions showed no statistically significant differences or interaction for the variables gender, expertise, and service (p < 0.0017). Qualitative analysis found discernable heuristics and ideation that was indicative of the presence of implicitly learned tacit knowledge in study participants; the utility of tacit knowledge emerged during direct observation or when participant's engaged in analogy, storytelling, and metaphor. The participants in this study used introspeculation, a learning style framed by reflection and introspection on the validity of one's own knowledge and the value of what is learned from life experience and in the classroom. The introspeculative examined the presence and utility of tacit knowledge in decision-making, and questioned the veracity of sources and resources that guide them on the path of life. The study suggested that tacit knowledge not only informs the practice of therapists and technology users but may assist classroom teachers facing student involvement in individual education plans (IEPs), Individuals with Disabilities Education Act (IDEA), or section 504 of the Americans with Disabilities Act (ADA).

Healthy individuals can adjust their movements when changes arise to the body or the environment. Advanced age is associated with central and peripheral changes that may negatively impact one’s ability to adapt motor performance, such us upper-limb (UL) reaching movements. In this thesis, we conducted four studies to address the impact of aging on coordination and adaptation of goal-directed reaches. In the first experiment, we examined compensatory arm–trunk coordination in older adults during trunk-assisted reaching, using two motor tasks : 1) the Stationary Hand Task (SHT) in which older and young participants were asked to maintain a fixed hand position while flexing forward at the trunk, and 2) the Reaching Hand Task (RHT) in which participants were instructed to reach to a within-arm’s reach target while simultaneously flexing forward at the trunk (Raptis et al., 2007; Sibindi et al., 2013). We found that in SHT, young and older participants were able to maintain a stable hand position and compensate for trunk movement by appropriate angular rotations at the elbow and shoulder joints. As well, in the RHT, both groups made similar small overshoot errors. However, older participants performance was significantly more variable compared to young adults. These results suggest that older adult preserve their ability to coordinate arm and trunk movements efficiently during reaching but are not as consistent as young adults. In the second experiment, we sought to determine the ability of older adults to adjust shoulder and elbow coordination in response to changing task demands. Thus, we asked young and older adults to perform the RHT of Raptis et al. (2007) from the first experiment. A detailed comparison of UL kinematics during reaches in the presence and absence of trunk motion (i.e., free- vs. blocked-trunk trials) was performed and compared between young and older adults. We found that participants in both age group were able to coordinate motion at the elbow and shoulder joints in accordance with motion at the trunk. However, the extent of changes at the UL joints was smaller and more variable in older adults compared to young ones, especially when trunk motion was involved. These results imply that older adults can coordinate their UL movements based on task requirements, but with less consistent performance compared to young adults. In the third experiment, we investigated the preservation of intermanual transfer and retention of implicit visuomotor adaptation in older adults. We had young and older participants train to reach with visual feedback rotated 30° counter-clockwise relative to their actual hand motion. Furthermore, we examined whether providing augmented somatosensory feedback regarding movement endpoint would enhance visuomotor adaptation. We found that older adults demonstrated a comparable magnitude of implicit adaptation, transfer, and retention of visuomotor adaptation as observed in young adults, regardless of the presence of augmented somatosensory feedback. These results indicate that intermanual transfer and retention do not differ significantly between young and older adults when adaptation is driven implicitly, regardless the availability of augmented somatosensory feedback. In the fourth experiment, we looked to determine age-related differences in the engagement of offline and online control processes during implicit visuomotor adaptation. A detailed analysis of reaching performance was conducted and between young and older adults, during and after visuomotor adaptation. We found that when rotation was introduced, participants in both age took longer time to complete their movements, reached with a lower peak velocity and spent more time homing in on the target compared to reaches with aligned cursor feedback. Additionally, older adults had more curved paths with rotated cursor feedback compared to their reaches with aligned cursor feedback. Moreover, these changes in reaching performance continued following adaptation for both groups. These results suggest that young and older adults engage more in online control processes during implicit visuomotor adaptation. Together, these studies show that older adults: 1) maintain the ability to use compensatory arm-trunk coordination to maintain reaching accuracy, 2) preserve the ability to adjust the coordination between UL joints to meet task demands, 3) maintain the ability to adjust reaches to meet changes in the reaching environment, as well as transfer and retain the newly acquired movement, and 4) preserve the ability to modify the control processes underlying these adapted movements to meet the demands of the reaching environment. In conclusion, the flexibility to coordinate and adapt upper limb reaching performance to meet changes in task demands is maintained across lifespan.

Although the concept of culturally responsive practices (CRP) began in the 1990’s, intentional study and professional development varies across schools and districts with limited impact on sustained pedagogical efficacy and shift, which is particularly concerning during the current socio-political climate. This phenomenological case study examined the impact on participants studying culturally responsive practices in peer led professional learning communities as a blueprint to feasibly address adult skill gaps. The study centers on four core questions on the impact of the initiative in general, the ability of participants to address implicit bias, the use of peer facilitation, and additional unforeseen factors related to this method of learning. Each participant ultimately indicated significant growth by moving from a technical approach to adaptive and cognitive shifts within the 6-month study, increased emphasis on reflective practice and elevated urgency to address culturally non-responsive practices. Finally, core conditions for successful implementation of peer-led professional learning communities studying culturally responsive practices are discussed. Schools and districts who recognize the need for staff to improve in cultural proficiency have few excuses pertaining to their ability to engage in this critical work, provided they have the courage and will to address implicit bias and culturally non-responsive pedagogy which negatively impacts BIPOC students across the nation and world.

Implicit family process rules refer to unspoken rules about family beliefs and expectations about communication, closeness, and organization and are an important dimension of family functioning that may have a powerful influence over adolescent psychological well being. This study focused on the relationship between implicit family process rules and adolescent psychological symptoms such as: Hostility, interpersonal sensitivity, depression, anxiety, and somatization. It was hypothesized that more facilitative implicit family process rules would be related to fewer adolescent psychological symptoms. In addition, a model was created that included theexogenousindependent variables of family status, (defined as intact-marriage or non-intact), treatment status (whether the adolescent was currently in a psychological treatment program or not), and gender to test their relationships to implicit family process rules and adolescent psychological symptoms. A non-treatment sample (N=99) was recruited in Utah County, Utah, using a sample of convenience. The treatment sample (N=144) was recruited from an adolescent residential wilderness therapy program located in Duchesne County, Utah. The Brief Symptom Inventory (BSI) and the Family Implicit Rules Profile (FIRP) were administered to each participant along with a questionnaire requesting demographic information. Structural equation modeling was used to explore the relationships between the exogenous variables, facilitative implicit family process rules, and adolescent psychological symptoms. The model was tested using AMOS statistical software. Results showed that implicit family process rules were significantly related to adolescent psychological symptoms such that facilitative rules were related to fewer psychological symptoms. Males reported more constraining rules on the Expressiveness subscale of the FIRP while females reported more symptomology on the Interpersonal Sensitivity subscale of the BSI. These findings support previous research on family dynamics and psychological functioning and support the hypothesis that perceived implicit family process rules are important to study in adolescents. This research is a step toward a more epistemological approach to family therapy with adolescents as well as a step toward more preventative family therapy and education by addressing family rules. Implications for family therapists and future research are discussed.

The purpose of this study was to examine how implicit family process rules are related to observed child emotional responsiveness with child self regulation as a possible mediating variable. Data from Wave 1 of the Flourishing Families project was used and included 337 two parent families and a target child between the ages of 10 and 13. Mother and father perception of family implicit rules were used to measure family implicit rules; child and mother report of the child's self regulation were used to measure self regulation, and child's emotional responsiveness to mother and father were taken from coding data. The Iowa Family Interaction Rating Scales (Melby, et. al., 1998) were used to code the behavior of the child with mother and with father. Multiple Group Comparison using AMOS 16 was used to compare differences based on child gender. Results showed that family implicit rules were positively related to emotional responsiveness to mother for both sons and daughters and to emotional responsiveness to father for sons but not for daughters. Family implicit rules were positively related to child self regulation for both sons and daughters, and self regulation was related to both emotional responsiveness to mother and to father. Results indicated child self regulation significantly mediated the relationship between family implicit rules and emotional responsiveness to mother as well as the relationship between implicit rules and emotional responsiveness to father. Implications for family therapy are discussed.

This study explored the main effects and interaction effects of implicit learning and explicit instructional approaches on the language acquisition of beginning adult and child learners of Chinese and analyzed the successful adult and child learners' learning styles in their information processing time, second language acquisition techniques, and cognitive strategies. Volunteers from Brigham Young University and Wasatch Elementary School were randomly assigned to either an Explicit Instruction Treatment (EIT) or an Implicit Learning Treatment (ILT). Following the treatment, the participants completed an online survey and a vocabulary application test. Results from a 2 x 2 factorial ANOVA indicated that adults performed significantly better than children on the listening and vocabulary tests scores (F (1, 135) =158.901, p<.001), and the EIT was significantly more effective than the ILT. There was no interaction between maturity and treatment factors. Results from a 3 x 2 factorial MANOVA indicated that in the Learning Phase, adults in the high and mid performance groups spent significantly longer processing information than those in the low performance group, and adults in the EIT also spent a longer time than those in the ILT. Results from the stepwise regression showed that for successful adult and child learners, Phonological Processing was the most frequently used second language strategy for both adults and children, which was strongly correlated with their vocabulary application test scores. Guessing was the most popular cognitive strategy. Successful children spent significantly less time than the low performing children in the Testing Phase.
