Reading the same storybooks repeatedly helps preschool children learn words. In addition, sleeping shortly after learning also facilitates memory consolidation and aids learning in older children and adults. The current study explored how sleep promotes word learning in preschool children using a shared storybook reading task. Children were either read the(More)
BACKGROUND HIV-infected women are at increased risk for developing cervical cancer. Women living in resource-limited countries are especially at risk due to poor access to cervical cancer screening and treatment. We evaluated three cervical cancer screening methods to detect cervical intraepithelial neoplasia grade 2 and above (CIN 2+) in HIV-infected women(More)
BACKGROUND The risk of squamous intra-epithelial lesions (SIL) is higher in HIV-positive women. As these women begin to live longer due to highly active antiretroviral therapy (HAART), their risk of cervical cancer may increase. Few data exist regarding the effect of HAART on the incidence and progression of SIL in HIV-positive African women. The aim of(More)
OBJECTIVE South Africa has very high rates of both HIV infection and cervical pathology. The management of ASC-H is colposcopy and directed biopsy, but with so many women diagnosed with HSIL and a dearth of colposcopy centres in South Africa, women with cytologic diagnosis of ASC-H may not be prioritized for colposcopy. The aim of this study was to(More)
BACKGROUND Attentional biases for pain-related information have been commonly reported in patients with chronic pain. Biases may also exist in individuals who recently experienced an episode of acute clinical pain, although limited investigation has been conducted. The present study is the first to explore attentional biases in women who experienced recent(More)
Cooperative social interaction is a complex skill that involves maintaining shared attention and continually negotiating a common frame of reference. Privileged in human evolution, cooperation provides support for the development of social-cognitive skills. We hypothesize that providing audio support for capturing playmates' attention will increase(More)
Sleep deprivation may lead to increased impulsivity, however, previous literature has focused on examining effects of total sleep deprivation (TSD) rather than the more common condition, partial sleep deprivation (PSD) or 'short sleep'. Moreover, it has been unclear whether PSD impacts impulse-related cognitive processes, and specifically if it(More)
In the first few years of life children spend a good proportion of time sleeping as well as acquiring the meanings of hundreds of words. There is now ample evidence of the effects of sleep on memory in adults and the number of studies demonstrating the effects of napping and nocturnal sleep in children is also mounting. In particular, sleep appears to(More)
BACKGROUND Polycystic ovary syndrome (PCOS) is a major public health problem that affects women's physical and mental health. According to the US National Institutes of Health Office of Disease Prevention, there is a need to improve public awareness of the syndrome among health care providers and the public. Women's magazines are a type of "edutainment"(More)
Background HIV-seropositive women have a higher risk of oncogenic HPV infection, cervical neoplasia, and cervical cancer than HIV-seronegative women. As HIV-seropositive women begin to live longer due to effective highly active antiretroviral therapy (HAART), their risk of developing cervical cancer may increase. Little data exist regarding the progression(More)
