Although the incidence of HIV in the United States is higher among men compared to women, the global proportion of women versus
men who are infected has been approximately 50% since the late 1990s. Women have been under-represented in neuropsychological
studies of HIV. A small number of studies have reported a significantly higher prevalence of neurocognitive impairment among
HIV+ women compared to HIV− controls regardless of symptom status and with or without an AIDS diagnosis. Impairment was most
evident on psychomotor tasks. The risk of neuropsychological impairment was increased among HIV+ women not on antiretroviral
therapy. Age and depressive symptoms also increase neurocognitive risk. New neurocognitive studies of ovarian steroid hormones,
PTSD and other psychiatric conditions are critical for addressing potential female-specific aspects of HIV-Associated Neurocognitive
Disorder. Such studies will also address questions regarding involvement of the hippocampus and verbal memory, which may be
of particular significance among HIV+ women.

This study investigated infants’ rapid learning of two novel words using a preferential looking measure compared with a preferential reaching measure. In Experiment 1, 21 13-month-olds and 20 17-month-olds were given 12 novel label exposures (6 per trial) for each of two novel objects. Next, in the label comprehension tests, infants were shown both objects and were asked, “Where’s the [label]?” (looking preference) and then told, “Put the [label] in the basket” (reaching preference). Only the 13-month-olds showed rapid word learning on the looking measure; neither age group showed rapid word learning on the reaching measure. In Experiment 2, the procedure was repeated 24 h later with 10 participants per age group from Experiment 1. After a further 12 labels per object, both age groups now showed robust evidence of rapid word learning, but again only on the looking measure. This is the earliest looking-based evidence of rapid word learning in infants in a well-controlled (i.e., two-word) procedure; our failure to replicate previous reports of rapid word learning in 13-month-olds with a preferential reaching measure may be due to our use of more rigorous controls for object preferences. The superior performance of the younger infants on the looking measure in Experiment 1 was not straightforwardly predicted by existing theoretical accounts of word learning. 相似文献

Mixed reality environments represent a new approach to creating technology-mediated experiences. However, there is a lack of empirical research investigating users' actual experience. The aim of the current exploratory, non-experimental study was to establish levels of and identify factors associated with presence, within the framework of Schubert et al.'s model of presence. Using questionnaire and interview methods, the experience of the final performance of the Desert Rain mixed reality environment was investigated. Levels of general and spatial presence were relatively high, but levels of involvement and realness were not. Overall, intrinsic motivation, confidence and intention to re-visit Desert Rain were high. However, age was negatively associated with both spatial presence and confidence to play. Furthermore, various problems in navigating the environment were identified. Results are discussed in terms of Schubert's model and other theoretical perspectives. Implications for system design are presented. 相似文献

Ambiguous loss is a newly identified type of loss that occurs when a loved one is physically present, but psychologically
absent. Dementia is just one example. Because the lost person is here, but not here, grief is frozen, life is put on hold,
and people are traumatized. With no official verification of death, no possibility of closure, and no rituals for support,
there is no resolution of grief (Boss 1999). Clergy, especially pastoral counselors, can witness and provide comfort for such uncanny loss because people rely on them
for support, not just from the clear loss of death, but from the ambiguous losses, catastrophic and ordinary, that inevitably
will occur across the life course. 相似文献

In a British sample, the wrong-number technique was used to examine levels of helping behavior shown toward lesbians and gay men. A wrong-number telephone call, from either a man who self-identified as gay or heterosexual, or a woman who self-identified as either lesbian or heterosexual, was made to 232 men and women. The caller requested help by asking the respondent to relay a message to his or her partner by telephone. As predicted, lesbians and gay men were less likely to be given help than were their same-gender heterosexual counterparts. However, lesbians were given a similar amount of help as were heterosexual men. Male participants were less likely to give help to gay men than to lesbians, but female participants were no less likely to help lesbians than gay men. The results suggest that, although lesbians and gay men meet discrimination in everyday life, the level of discrimination may differ. 相似文献

Suitable normative information on the Iowa Gambling Task (IGT) is not currently available, though it is clear that there is great individual variability in performance on this assessment tool. Given that the task is presumed to measure the emotion-based learning systems that are thought to form the biological basis of 'intuition,' there is some reason to think that education (especially tertiary education) might explicitly de-emphasise the role of emotion-based learning in decision-making. This suggests the paradoxical finding that better-educated participants should show poorer performance on the IGT. We recruited 30 participants (all female, all aged 18-25) to participate in a 'real money' version of the IGT. There was no significant difference in performance in blocks 1-3 of the task (trials 1-60). However, there was a substantial effect of education on the final two blocks (trials 61-100), such that the less-well-educated participants produced twice as much of an improvement over baseline as did their university-educated colleagues. A range of possible explanations for this remarkable finding are discussed. The most likely appears to be that tertiary education specifically discourages the use of emotion-based learning systems in decision-making. These findings bear on the extent to which education has a role to play in our reliance on cognition and emotion in decision-making, including the likely role of education in the generation and maintenance of false beliefs. 相似文献

The Iowa Gambling Task (IGT) has been widely used in the assessment of neurological patients with frontal lesions. Emphasis has been placed on the complexity of the task (i.e., four decks of varying contingency pattern) with the suggestion that the participant must use emotion-based learning to deal with a complex decision-making process. The present study used a single deck card game (the Bangor Gambling Task, BGT), matched in many respects with the Iowa Gambling Task, in which the contingencies varied over time (gradually becoming worse for the participant) rather than across deck (as in the IGT). Forty participants performed both tasks. Performance on the tasks showed many similarities, with participants showing a comparable pattern of incremental learning on both tasks, reaching an analogous final level of performance. More importantly, there was a high correlation (r(2) = .93) in performance between the two tasks, the most salient feature of which was that virtually every participant who fell below categorisation of impaired IGT performance, also did very poorly on the BGT. These findings bear on the question of whether arguments about the 'complexity' of the Iowa Gambling Task necessarily explain why it appears to require emotion-based learning. The Bangor Gambling Task might also be a useful tool for clinical neuropsychologists, in the assessment of patients with executive dysfunction-given that the task is easier and quicker to administer than the Iowa Gambling Task, but appears to share the same performance features. 相似文献
