Purpose This study continued Phase I investigation of a modified Phonomotor Treatment (PMT) Program on motor planning in two individuals with apraxia of speech (AOS) and aphasia and, with support from prior work, refined Phase I methodology for treatment intensity and duration, a measure of communicative participation, and the use of effect size benchmarks specific to AOS. Method A single-case experimental design with multiple baselines across behaviors and participants was used to examine acquisition, generalization, and maintenance of treatment effects 8–10 weeks posttreatment. Treatment was distributed 3 days a week, and duration of treatment was specific to each participant (criterion based). Experimental stimuli consisted of target sounds or clusters embedded nonwords and real words, specific to each participants' deficit. Results Findings show improved repetition accuracy for targets in trained nonwords, generalization to targets in untrained nonwords and real words, and maintenance of treatment effects at 10 weeks posttreatment for one participant and more variable outcomes for the other participant. Conclusions Results indicate that a modified version of PMT can promote generalization and maintenance of treatment gains for trained speech targets via a multimodal approach emphasizing repeated exposure and practice. While these results are promising, the frequent co-occurrence of AOS and aphasia warrants a treatment that addresses both motor planning and linguistic deficits. Thus, the application of traditional PMT with participant-specific modifications for AOS embedded into the treatment program may be a more effective approach. Future work will continue to examine and maximize improvements in motor planning, while also treating anomia in aphasia.

The Worry Domains Questionnaire was proposed as a measure of both pathological and nonpathological worry, and assesses the frequency of worrying about five different domains: relationships, lack of confidence, aimless future, work, and financial. The present study analyzed the factor structure of the long and short forms of the WDQ (WDQ and WDQ-SF, respectively) through confirmatory factor analysis in a sample of 262 students (M age = 21.8; SD = 2.6; 86.3% females). While the goodness-of-fit indices did not provide support for the WDQ, good fit indices were found for the WDQ-SF. Furthermore, no source of misspecification was identified, thus, supporting the factorial validity of the WDQ-SF scale. Significant positive correlations between the WDQ-SF and its subscales with worry (PSWQ), anxiety (STAI-T), and depression (BDI) were found. The internal consistency was good for the total scale and for the subscales. This work provides support for the use of the WDQ-SF, and potential uses for research and clinical purposes are discussed.

Future Work

Previous work has shown that is important to consider the disjunction between paranormal and nonparanormal beliefs about extraterrestrial life. The current study examined the association between both such beliefs and individual difference and demographic variables. A total of 555 British participants completed the Extraterrestrial Beliefs Scale, as well as measures of their Big Five personality scores, social conformity, sensation seeking, and demographics. Results showed no sex differences in ratings of paranormal and nonparanormal extraterrestrial beliefs, but participants rated nonparanormal beliefs more positively than paranormal beliefs. Results of structural equation modeling showed that individual difference factors (specifically, Openness, Conscientiousness, and social conformity) explained 21% of the variance in extraterrestrial beliefs, whereas demographic factors (specifically, education level, political orientation, and religiosity) explained 16% of the variance. Limitations and directions for future work are considered.

Opening Up

By reading written and visual artefacts of Gertrude Stein’s life, Gertrude Stein’s Transmasculinity reframes earlier scholarship to argue that her gender was transmasculine and that her masculinity was positive rather than a self-hating form of false consciousness. This book considers ways Stein’s masculinity was formed through her relationship with her feminine partner, Alice B. Toklas, and her masculine homosocial bonds with other modernists in her network. This broadens out Eve Kosofsky Sedgwick’s account of “male homosocial bonding” to include all masculine persons, opening up the possibility of examining Stein’s relationship to Toklas; masculine women such as Jane Heap; and men such as Pablo Picasso, Ernest Hemingway, and Carl Van Vechten. The Introduction and first four chapters focus on surfacings of Stein’s masculinity within the visual and the textual: in others’ paintings and photographs of her person; her hermetic writings from the first three decades of the twentieth century; and her self-packaging for mass consumption in The Autobiography of Alice B. Toklas (1933). Whereas the chapter on The Autobiography underscores Toklas’s role in the formation of Stein’s masculinity and success as a modernist, the final three register the vicissitudes of the homosocial bonds at play in her friendships with Picasso, Hemingway, and Van Vechten. The Coda, which cross-reads Stein’s Everybody’s Autobiography (1937) with the media attention two museum exhibits about her attracted between 2011 and 2012, points to possibilities for future work on the implications of her masculine homosocial bonds with Vichy collaborator Bernard Fäy.
