Purpose We report on a study that replicates previous treatment studies using Abstract Semantic Associative Network Training (AbSANT), which was developed to help persons with aphasia improve their ability to retrieve abstract words, as well as thematically related concrete words. We hypothesized that previous results would be replicated; that is, when abstract words are trained using this protocol, improvement would be observed for both abstract and concrete words in the same context-category, but when concrete words are trained, no improvement for abstract words would be observed. We then frame the results of this study with the results of previous studies that used AbSANT to provide better evidence for the utility of this therapeutic technique. We also discuss proposed mechanisms of AbSANT. Method Four persons with aphasia completed one phase of concrete word training and one phase of abstract word training using the AbSANT protocol. Effect sizes were calculated for each word type for each phase. Effect sizes for this study are compared with the effect sizes from previous studies. Results As predicted, training abstract words resulted in both direct training and generalization effects, whereas training concrete words resulted in only direct training effects. The reported results are consistent across studies. Furthermore, when the data are compared across studies, there is a distinct pattern of the added benefit of training abstract words using AbSANT. Conclusion Treatment for word retrieval in aphasia is most often aimed at concrete words, despite the usefulness and pervasiveness of abstract words in everyday conversation. We show the utility of AbSANT as a means of improving not only abstract word retrieval but also concrete word retrieval and hope this evidence will help foster its application in clinical practice.

Abstract Background STEM identity has been shown to have a powerful role in an individual’s success in educational environments, as well as on their career goals and trajectories. Historically, however, STEM identity formation for underrepresented students has been hampered by the lack of representation of in STEM fields, which predominantly consist of white males. One educational challenge is diversifying STEM classrooms, both in terms of the students themselves and also in terms of the science and scientists they learn about. Methods We piloted a 4-credit History, Philosophy, and Sociology of Science course at Michigan State University. Students were tasked with creating exhibits focused on themes of diversity and inclusion in science for a real client. Using a STEM identity survey, we assessed students’ attitudes towards the sciences, issues of diversity in science, and their sense of belonging to their educational communities. We also had the students respond to various short-answer questions throughout the semester to better understand their experiences working on a collaborative authentic learning task. Results Our results suggest that authentic learning experiences based around ideas of diversity and inclusion can help students develop sense of belonging and positive STEM identities. Students demonstrated shifts in their self-identities as scientists, focusing more on the intersection between their gender, ethnicity, and self-perception as a scientist. Through qualitative analysis of short-answer questions, we were able to ascertain that working in groups in an authentic learning environment helped the students improve their communication and collaboration skills. Conclusions Students’ increased focus on gender and ethnicity suggests that they are thinking critically about how their personal identities intersect with their scientific identities. Additional research would help us better understand if the coupling of authentic learning and inclusive teaching practices have significant impacts on the formation of students’ STEM identities.
