Parents may be reluctant to treat the feeding disorder of a chronically ill child who exhibits distressed behavior during feeding. In this study, we identified a child with chronic medical problems and a feeding disorder who cried during feedings. We introduced treatment components sequentially to address parental concerns about crying. First, we used a pacifier to reduce crying, and then we used a flipped spoon to increase mouth clean. The results showed that a sequential approach to treatment can be effective for children with complex medical and behavioral problems. 相似文献

We studied the extent to which subjective ratings of memory phenomenology discriminate true‐ and false‐memory responses, and whether degree of gist‐based processing influences false memory and phenomenology, in a classic forensic task, the Gudjonsson Suggestibility Scale (GSS). Participants heard a narrative of a robbery followed by suggestive questions about the content of the narrative. They were asked to rate the items they recognized as studied using the Memory Characteristics Questionnaire (MCQ). Consistent with studies of word lists, there were phenomenological differences between true and false memory responses: memory phenomenology was richer for true than for false memories, which supports opponent‐process accounts of false memory such as fuzzy‐trace theory. Thus, phenomenology is a useful means for differentiating experienced from non‐experienced events in forensic contexts. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Although the amnestic effects of alcohol in humans are well known, its effects on emotional memory are unclear. In this study, using a randomized double-blind placebo-controlled design, we examine narrative emotional episodic memory in healthy human female volunteers (n = 32) who received either a single dose of alcohol (0.6 g/kg), or a placebo and then viewed neutral story elements presented in either a neutral or emotional context. Memory was tested for gist and detail of the neutral elements 3 days later in a surprise recognition test. Since alcohol modulates GABAergic neurotransmission and may exert its effects on emotion through the limbic system, we predicted that acute alcohol treatment would reduce the expected emotional memory-advantage for gist, leaving detail memory relatively unaffected. Furthermore, given previous findings showing that ‘primacy’ memory is enhanced by physiological arousal, we predicted that reduced arousal produced by alcohol would have the opposite effect and impair primacy memory relative to the middle or ‘recency’ sections of the narrative. Emotional arousal was expected to oppose this effect, so impaired primacy memory following alcohol was only expected in the neutral version of the narrative. Although there was a main effect of story phase (though not of story version), contrary to expectations, alcohol impaired primacy memory for emotionally encoded neutral material. The results suggest that under certain circumstances emotional context or physiological arousal make memories labile and susceptible to disruption through pharmacological manipulation during encoding. 相似文献

A social indicators community project was conducted in 2007 to monitor living standards and quality of life in Rhini, a low-income
suburb of Grahamstown, Makana Municipality, South Africa. Since 1994, under democratic rule, considerable progress has been
made in service delivery to the formerly disadvantaged in South African society in terms of access to housing, infrastructure,
and a social safety net to mitigate the high rate of unemployment. A representative cross-sectional household study (n 1020)
conducted in 2007 in Rhini found that a positive assessment of the household’s situation and personal life satisfaction did
not reflect better living conditions. Lack of income and employment opportunities appeared to dilute gains from higher living
standards. The project also inquired into attitudes to place names and a proposed name change for the city under discussion
at the time of the survey. It is argued that a place name with which one can identify may be as important as service delivery
to enhance community satisfaction and overall quality of life. Dissatisfied residents who had limited access to services and
expressed less civic pride were more likely than others to opt for a proposed name change for the city of Grahamstown that
would better reflect the country’s new identity and multicultural heritage. It is concluded that a useful pursuit for community
quality-of-life studies in countries undergoing social transformation will be to inquire into the complex combination of factors
that drive perceptions of material and symbolic progress. 相似文献

CONTEXT: Alcohol use is frequently identified as a contributor to risky sexual behaviors; however, research results are mixed. Given the conflicting evidence, researchers have focused on other factors, such as expectations about alcohol's effects that might help explain the relationship of alcohol use and risky sexual behaviors. METHODS: Cross-sectional data from 312 sexually experienced males aged 18-30 in a shantytown in Lima, Peru, were used in logistic regression models to identify associations of heavy episodic drinking and sex-related expectations about alcohol with sexual risk behaviors. RESULTS: Heavy episodic drinking was associated with having had two or more sexual partners and having had sex with a casual partner in the past year (odds ratios, 2.8 and 2.5, respectively). After controlling for alcohol consumption, sex-related expectations about alcohol were associated with these high-risk sexual behaviors, as well as with not using a condom at last sex (1.2) and not using a condom at last sex with a casual partner (1.3). CONCLUSION: Beliefs about the effect of alcohol on sexual performance could help explain links between alcohol consumption and risky sexual behavior not completely accounted for by the pharmacological effects of alcohol. 相似文献

Although previous research demonstrated that networks matter for health-related outcomes, few studies have investigated the possibility that network effects may differ between women and men. In a multivariate regression analysis of a US sample of 548 hurricane victims, we ask whether effects of network composition, density, and size affect perceived adequacy of social support and depressive symptoms more strongly among women than among men. We find evidence for these moderating effects, for direct effects of density on support adequacy and size on depressive symptoms. Our examination of indirect effects of network structure on depressive symptoms, in the pathway through perceived adequacy of social support, suggests that gender may exert more substantial moderating effects than previous health studies suggest. 相似文献

Although prior research has examined predictions of memory performance under conditions of interference at encoding, predictions
of memory performance have not been examined for interference introduced via cues at retrieval. This was investigated in the
present study by exposing participants to a random subset of to-be-recalled items just prior to retrieval (part-set cuing)
and then eliciting an overall prediction of memory performance. Across three experiments, participants in part-set cuing conditions
recalled proportionally fewer items than did participants who were not exposed to any cues. However, participants were unable
to predict the detrimental effect of part-set cues on memory performance in either a semantic (Experiment 1) or an episodic
(Experiment 2) memory task. Predictions were better calibrated after practice with part-set cuing, and there was evidence
that prior experience with part-set cuing transferred to predictions made for a different part-set cuing task (Experiment
3). This suggests that only under some conditions are participants sensitive to the diminished accessibility of memories wrought
by part-set cues and illustrates situations in which participants are or are not aware of variables at retrieval that influence
memory performance. 相似文献

Evaluating whether a limited sample of evidence provides a good basis for induction is a critical cognitive task. We hypothesized that whereas adults evaluate the inductive strength of samples containing multiple pieces of evidence by attending to the relations among the exemplars (e.g., sample diversity), six-year-olds would attend to the degree to which each individual exemplar in a sample independently appears informative (e.g., premise typicality). To test these hypotheses, participants were asked to select between diverse and non-diverse samples to help them learn about basic-level animal categories. Across various between-subject conditions (N=133), we varied the typicality present in the diverse and non-diverse samples. We found that adults reliably selected to examine diverse over non-diverse samples, regardless of exemplar typicality, six-year-olds preferred to examine samples containing typical exemplars, regardless of sample diversity, and nine-year-olds were somewhat in the midst of this developmental transition. 相似文献

Research has demonstrated that interspersing mastered tasks with new tasks facilitates learning under certain conditions; however, little is known about factors that influence the effectiveness of this treatment strategy. The initial purpose of the current investigation was to evaluate the effects of similar versus dissimilar interspersed tasks while teaching object labels to children diagnosed with autism or developmental delays. We then conducted a series of exploratory analyses involving the type of reinforcer delivered for correct responses on trials with unknown or known object labels. Performance was enhanced under the interspersal condition only when either brief praise was delivered for all correct responses or presumably more preferred reinforcers were provided for performance on known trials rather than on unknown trials. 相似文献
