Children of HIV-infected mothers have more psychosocial adjustment difficulties than do those of noninfected mothers. In this study, child psychosocial adjustment in children of HIV-infected women is examined across the three stages of HIV-infected: asymptomatic, symptomatic and AIDS. Participants were 99 HIV-infected women and 148 noninfected women. Children were not identified as being HIV infected. Mother and child reports of behavioral difficulties are compared, and competing hypotheses about mother report of child behavior difficulties are tested. Results indicate an ascending linear trend for child report of internalizing and externalizing difficulties from the noninfected stage through increasingly severe stages of HIV-infection. According to mother report, child externalizing and internalizing difficulties are nonlinear, as mothers report an increase through the infected symptomatic stage, then a decrease in the AIDS stage. Implications for assessment, prevention and intervention in families with maternal HIV infection are discussed. 相似文献

Must readers intend to process a word to activate various levels of representation, or is such processing simply triggered by the presentation of a word (i.e., is it “automatic”)? This issue was addressed via the use of Besner and Care’s Task Set paradigm. On each trial a cue, which indicated which of two tasks to perform appeared either before the target, or at the same time as the target. If subjects can process the target while preparing a task set, then the effect of a manipulated psycholinguistic factor should be absorbed into the time taken to process the cue. Despite robust main effects of SOA and word frequency there was no interaction between these factors when the task was to read aloud. This result implies that target processing is delayed until the subject knows what task to perform, and therefore that intention plays an important role when reading words aloud. 相似文献

The field of genetic counseling faces a broad challenge: many potential clients may not be aware of the value and benefit
of genetic counseling services, and therefore may not utilize those services. Navigenics is a personal genomic testing company
that provides telephonic genetic counseling services for multifactorial diseases and pharmacogenetics. When first offered
in 2008, utilization of the Navigenics genetic counseling service was less than expected. To explore the basis for under-utilization
and potential mechanisms for increasing uptake, Navigenics initiated a quality improvement study, in which three different
methods of engaging clients in the uptake of genetic counseling services were assessed over the course of 1 year. Outcomes
showed significant differences in uptake rates between methodologies (7.5%, 24.6%, and 60.1%), yielding an 8-fold increase
in service utilization when post-test telephonic outreach to all clients was performed. Further, utilization spanned all risk
levels based on client results, evidence that not only clients with high-risk results were motivated to engage in the genetic
counseling service. This research indicates that implementing strategies to educate clients about genetic counseling can positively
impact client engagement and utilization of available services. 相似文献

Very little research has focused on rates of trauma exposure for youth in treatment foster care (TFC). Available research has utilized record review for assessing exposure, which presents limitations for the range of trauma types examined, as records are predominantly focused on abuse and neglect. The current study examines exposure rates and association with emotional and behavioral outcomes for 229 youth in 46 TFC agencies. The youth in this study had exceptionally high rates of trauma exposure by foster parent report, similar to youth in traditional foster care, with nearly half of the sample exposed to four or more types of traumatic events. A composite child abuse and neglect exposure variable was associated with child and adolescent emotional and behavioral outcomes. Implications for services provided as part of TFC are discussed. 相似文献

Benchmarking is a program evaluation approach that can be used to study whether the outcomes of parents/children who participate in an evidence-based program in the community approximate the outcomes found in randomized trials. This paper presents a case illustration using benchmarking methodology to examine a community implementation of Parent–Child Interaction Therapy (CI-PCIT) utilized as a child maltreatment prevention effort. Data were collected from 83 parent–child dyads. Change scores were compared to treatment and control effect sizes aggregated from the PCIT literature. Pre-post results indicated significant positive changes in child behavior for CI-PCIT completers. Benchmarking analyses revealed that parents who completed CI-PCIT reported significantly greater positive child outcomes than the aggregate control group benchmark, and significantly less than observed in the treatment benchmark. A summary of decision points and implications for utilizing this methodology in the child maltreatment field are postulated. 相似文献

Pigs are a valuable animal model for studying neurodevelopment in humans due to similarities in brain structure and growth. The development and validation of behavioral tests to assess learning and memory in neonatal piglets are needed. The present study evaluated the capability of 2-week old piglets to acquire a novel place and direction learning spatial T-maze task. Validity of the task was assessed by the administration of scopolamine, an anti-cholinergic drug that acts on the hippocampus and other related structures, to impair spatial memory. During acquisition, piglets were trained to locate a milk reward in a constant place in space, as well as direction (east or west), in a plus-shaped maze using extra-maze visual cues. Following acquisition, reward location was reversed and piglets were re-tested to assess learning and working memory. The performance of control piglets in the maze improved over time (P < 0.0001), reaching performance criterion (80 % correct) on day 5 of acquisition. Correct choices decreased in the reversal phase (P < 0.0001), but improved over time. In a separate study, piglets were injected daily with either phosphate-buffered saline (PBS; control) or scopolamine prior to testing. Piglets administered scopolamine showed impaired performance in the maze compared to controls (P = 0.03), failing to reach performance criterion after 6 days of acquisition testing. Collectively, these data demonstrate that neonatal piglets can be tested in a spatial T-maze task to assess hippocampal-dependent learning and memory. 相似文献

Participants were presented with sentences mentioning an entity with a typical location in the upper or lower vertical space (e.g., roof vs. root). Sentences supported or reversed the typical location of the target entity. Sensibility judgments requiring upwards or downwards responses were faster when the response matched rather than mismatched the target entity's typical location. This compatibility effect was independent of whether the sentence context supported or reversed the target entity's typical location. The results, therefore, provide clear evidence for word-based but no evidence for sentence-based simulation processes. 相似文献

Behavioral activation that is associated with incentive-reward motivation increases in adolescence relative to childhood and adulthood. This quadratic developmental pattern is generally supported by behavioral and experimental neuroscience findings. It is suggested that a focus on changes in dopamine neurotransmission is informative in understanding the mechanism for this adolescent increase in reward-related behavioral activation and subsequent decline into adulthood. Evidence is presented to indicate that incentive-reward motivation is modulated by mesoaccumbens dopamine, and that it increases in adolescence before declining into adulthood because of normative developmental changes at the molecular level. Potential mechanisms of variation in functional mesoaccumbens dopamine transmission are discussed with a focus on the interplay between tonic and phasic modes of dopamine transmission in modulating both general incentive-motivational biases and the efficacy of reward learning during exposure to novel reward experiences. Interactions between individual difference factors and these age-related trends are discussed. 相似文献

Feedback on task performance is often phrased in subjective language (e.g., “not bad!”), but how do recipients understand or translate that feedback into a clear, objective, performance metric? We suggest that when feedback is provided in a stereotype-relevant domain, translation is made with reference to stereotyped expectations for one's group. In Study 1, women and men were exposed to negative subjective feedback about their performance on a leadership task; in Study 2, Black and White participants were provided subjective negative feedback, or no feedback, on an academic writing task. Women relative to men, and Black students relative to White students, translated their feedback to indicate objectively worse performance. Furthermore, this translation mediated a drop in the importance placed on the domain among women and Blacks. This research extends the literature on gender- and race-based reactions to feedback by noting the importance of the immediate interpretation of the feedback received. 相似文献
