Given the burden of depression among those with HIV, and the impact of HIV on urban minority communities there is an urgent need to assess innovative treatment interventions that not only treat depression but do so in a way that allows for increased access to mental health care. This single site, uncontrolled, pilot study sought to determine the feasibility and depression outcomes of an 11-session telephone-based cognitive behavioral therapy intervention delivered over 14 weeks targeting low-income, urban-dwelling, HIV-infected African-American people with major depression. The diagnosis of major depression was made using the Mini International Neuropsychiatric Interview. The primary outcome was the Hamilton Depression Rating Scale (HAM-D) and the secondary outcome was the Quick Inventory of Depression Symptomatology-Self Report (QIDS-SR). Feasibility and satisfaction were also assessed. Assessments occurred at baseline, midpoint and at study conclusion (14 weeks). Fifteen people were screened for the study. Six HIV-infected, low-income, African-American people individuals (five females and one male) were eligible and participated in the study. All patients finished the study. On average, participants completed nine sessions. The sessions lasted for an average of 48 min (SD = 11.5). Compared to mean HAM-D score at baseline (HAM-D = 22.8 (SD = 3.1), the mean HAM-D score was significantly reduced at study conclusion (HAM-D = 9.8 (SD = 7.4); (t (5) = 4.6, p = 0.006); (Cohen d = 1.9)). Compared to the mean QIDS-SR score at baseline (QIDS-SR = 15.5 (SD = 4.2) the mean QIDS score was significantly reduced at study conclusion (QIDS = 7.0 (SD = 5.4);(t (5) = 3.2, p = 0.02); (Cohen d = 1.3)).The mean satisfaction scores across all participants at post-treatment was 5.7 (SD = 0.3) with of a maximum score of 6. Telephone-based CBT can be delivered to low-income, urban-dwelling ethnic minority HIV-infected people resulting in significant reductions in depression symptoms with high satisfaction. The efficacy of this intervention will be assessed in a planned randomized control trial. 相似文献

The IIFF model of organ donation holds that the simultaneous presence of four factors directly influence donor registration: (1) immediate and complete registration opportunity (ICRO), (2) information, (3) focused engagement, and (4) favorable activation. Two field experiments examined the impact of an ICRO on organ donation registration. In Study 1, participants were at town halls where they knew organ donation was to be discussed. Registration cards were distributed and then collected at the end of the session in half of the town halls. For the other half, participants were asked to mail in completed cards. In three US cities, participants given an ICRO registered at a significantly greater rate (z?=?4.865, p?0.05). Study 2, targeting Hispanics at a swap meet, differed in that the registration impact of awareness of the availability of an ICRO was investigated. Participants made aware of an ICRO registered at a significantly greater rate (z?=?4.1, p?=?0.000). 相似文献

A current theory of attention posits that several micro-indices of attentional vigilance are dependent on activation of the locus coeruleus, a brainstem nucleus that regulates cortical norepinephrine activity (Aston-Jones et al., 1999). This theory may account for many findings in the infant literature, while highlighting important new areas for research and theory on infant attention. We examined the visual behaviors of n = 16 infants (6-7 months) while they attended to multiple spatially distributed targets in a naturalistic environment. We coded four measures of attentional vigilance, adapted from studies of norepinergic modulation of animal attention: rate of fixations, duration of fixations, latency to reorientation, and target 'hits'. These measures showed a high degree of coherence in individual infants, in parallel with findings from animal studies. Results also suggest that less vigilant infants showed greater habituation to the trial structure and more attentiveness to less salient stimuli during periods of high attentional competition. This pattern of results is predicted by the Aston-Jones model of attention, but could not be explained by the standard information processing model. 相似文献

We establish attentional capture by emotional distractor faces presented as a "singleton" in a search task in which the emotion is entirely irrelevant. Participants searched for a male (or female) target face among female (or male) faces and indicated whether the target face was tilted to the left or right. The presence (vs. absence) of an irrelevant emotional singleton expression (fearful, angry, or happy) in one of the distractor faces slowed search reaction times compared to the singleton absent or singleton target conditions. Facilitation for emotional singleton targets was found for the happy expression but not for the fearful or angry expressions. These effects were found irrespective of face gender and the failure of a singleton neutral face to capture attention among emotional faces rules out a visual odd-one-out account for the emotional capture. The present study thus establishes irrelevant, emotional, attentional capture. 相似文献

This longitudinal assessment concentrated on the relation between the home literacy environment (HLE) and early language acquisition during infancy and toddlerhood. In study 1, after controlling for socio‐economic status, a broadly defined HLE predicted language comprehension in 50 infants. In study 2, 27 children returned for further analyses. Findings revealed that the HLE measured in infancy predicted language production in toddlerhood and maternal redirecting behaviours measured in toddlerhood were negatively associated with expressive language. Results across both studies indicate the importance of a broadly defined HLE (including joint attention and parent–child conversation) for language development. Taken together, these findings highlight the importance of the HLE in supporting both receptive and expressive vocabulary growth in the second and third years of life.

Dominance and submission constitute fundamentally different social interaction strategies that may be enacted most effectively to the extent that the emotions of others are relatively ignored (dominance) versus noticed (submission). On the basis of such considerations, we hypothesized a systematic relationship between chronic tendencies toward high versus low levels of interpersonal dominance and emotion decoding accuracy in objective tasks. In two studies (total N = 232), interpersonally dominant individuals exhibited poorer levels of emotion recognition in response to audio and video clips (Study 1) and facial expressions of emotion (Study 2). The results provide a novel perspective on interpersonal dominance, suggest its strategic nature (Study 2), and are discussed in relation to Fiske's (1993) social-cognitive theory of power. 相似文献

Although the majority of research focuses on the risks and disadvantages of online gaming, the present authors suggest that
online games also represent new ways of satisfying basic human needs within the conditions of modern society. The aim of our
present study was to reveal and operationalize the components of the motivational basis of online gaming. A total 3,818 persons
(90.6% males; mean age 20.9 years, SD = 5.81) were recruited through websites providing online games. A combined method of exploratory and confirmatory factor
analysis was applied. The results confirmed our preliminary model as we identified seven motivational factors (social, escape,
competition, coping, skill development, fantasy, and recreation), which were used to develop the 27-item Motives for Online
Gaming Questionnaire (MOGQ). The seven dimensions identified seem to cover the full range of possible motives for gaming, and the MOGQ proved to be an
adequate measurement tool to assess these motives. 相似文献

Semantic memory is the subsystem of human memory that stores knowledge of concepts or meanings, as opposed to life-specific experiences. How humans organize semantic information remains poorly understood. In an effort to better understand this issue, we conducted a verbal fluency experiment on 200 participants with the aim of inferring and representing the conceptual storage structure of the natural category of animals as a network. This was done by formulating a statistical framework for co-occurring concepts that aims to infer significant concept-concept associations and represent them as a graph. The resulting network was analyzed and enriched by means of a missing links recovery criterion based on modularity. Both network models were compared to a thresholded co-occurrence approach. They were evaluated using a random subset of verbal fluency tests and comparing the network outcomes (linked pairs are clustering transitions and disconnected pairs are switching transitions) to the outcomes of two expert human raters. Results show that the network models proposed in this study overcome a thresholded co-occurrence approach, and their outcomes are in high agreement with human evaluations. Finally, the interplay between conceptual structure and retrieval mechanisms is discussed. 相似文献

Earlier studies have demonstrated that spatial cueing differentially reduces stimulus-stimulus congruency (e.g., spatial Stroop) interference but not stimulus-response congruency (e.g., Simon; e.g., Lupiá?ez & Funes, 2005). This spatial cueing modulation over spatial Stroop seems to be entirely attributable to object-based attention (e.g., Luo, Lupiá?ez, Funes, & Fu, 2010). In the present study, two experiments were conducted to further explore whether the cueing modulation of spatial Stroop is object based and/or space based and to analyse the "locus" of this modulation. In Experiment 1, we found that the cueing modulation over spatial Stroop is entirely object based, independent of stimulus-response congruency. In Experiment 2, we observed that the modulation of object-based attention over the spatial Stroop only occurred at a short cue-target interval (i.e., stimulus onset asynchrony; SOA), whereas the stimulus-response congruency effect was not modulated either by object-based or by location-based attentional cueing. The overall pattern of results suggests that the spatial cueing modulation over spatial Stroop arises from object-based attention and occurs at the perceptual stage of processing. 相似文献
