The theory-of-mind abilities of twins, children with nontwin siblings, and only children were compared to investigate further the link between number and type of siblings and theory-of-mind abilities. Three- to 5-year-old children with nontwin siblings outperformed both only children and twins with no other siblings, twins who also had other siblings outperformed twins who did not, and children with at least 1 opposite-sex sibling outperformed children with only same-sex siblings. Twins performed significantly better when asked about the false beliefs of their twins than they did when asked about the false beliefs of their friends. Results are discussed in terms of potential mechanisms that may account for the twin and sibling effects.

A recent study has suggested that observers' visual explorations of the external world can proceed unimpaired when the visual environment precludes the operation of memory processes (as, for instance, when the display elements change locations every 100 ms). One theoretical limitation of this study was that distractors were the only elements that had the potential to be tagged during visual search. The present study sought to clarify the amnesic-search hypothesis by investigating whether memory processes can guide search in other contexts in which targets also have the potential to be tagged. Accordingly, the experimental conditions of the previous study were repeated using a different search task in which observers had to decide whether one target or two were present among a variable number of similar distractors. Under these search conditions, the present findings provided strong evidence that memory processes can guide visual search.

A usability study of a Virtual Reality Sterile Urinary Catheter Insertion Game (VR SUCIG) was conducted to understand user needs in regards to this game. Background: Learning and retention of psychomotor skills in health care is essential to safe clinical practice. Bauman suggests games are most useful when they are part of a layered-learning approach; in other words, they support various forms of learning and serve as cognitive aids ( Bauman et al., 2014 ). Intervention: The VR Sterile Urinary Catheter Insertion Game (VRSUCIG) was created by nurses and a computer gaming developer to provide nursing students with a cost-effective way to practice sterile catheter insertion skills in a systematic, evidence-based manner. A usability study and user reaction survey were conducted to gain a deep understanding of user’s needs. Methods: Three hundred nursing students, from 9 US nursing schools participated. Participants played the VR SUCIG and completed the System Usability Scale (SUS) and a User Reaction Survey (URS). Results: The SUS for the 2nd generation of the VR SUCIG was 57, or medium usability. The URS demonstrated the game motivated them to keep practicing. The VR SUCIG promoted repetitive practice of the skill and visually accentuated the concept of sterility. Conclusions. User reactions indicate that nursing students were eager and excited to utilize this technology. Usability scores indicate further refinement of technology is needed.

This article discusses Brown’s use of Afrofuturism and critical pedagogy in her creation of the class, Black Women and the Pandemic Imagination (BWPI), which she taught in Spring 2021 at Virginia Commonwealth University. Brown explains her implementation of precarious pedagogy to attend to the affective needs of students struggling under the effect of Covid-19. She discusses how the analytics of Afrofuturism and critical pedagogy provide strategies for combating white supremacy and for promoting social justice. Brown demonstrates how reading theoretical works by black women about cataclysmic moments (i.e., the apocalypse, contagions, pandemics and even the Middle Passage), as well as studying representations of black women during these moments provides an opportunity for students to “rehearse hope.” Brown sees BWPI as a course premised on Black Lives Matter and committed to black futurity – “there are black people in the future.” Through BWPI, she hoped to ignite the radical imagination of her students, thereby empowering them to think about creating a more equitable future.
