ABSTRACTThe opportunity to observe or interact with animals in a zoo is often vital in influencing visitors' positive feelings towards animals and ultimately their conservation behavior. This study explores the relationship between observed animal behavior and zoo visitors' responses. A self-administered questionnaire was completed by 717 visitors across four exhibits (giraffe, lion, cheetah, and red panda) at three zoos (Brookfield Zoo, San Diego Zoo Safari Park, and Central Park Zoo). The questionnaire measured observed animal behaviors and visitors' predispositions, affective responses, and meaning-making at animal exhibits. Multivariate path analyses indicated that up-close encounters with zoo animals, along with observable active animal behaviors, predicted visitors' reported positive affective responses which, in turn, predicted their meaning-making. These findings lend support to the role of positive affect as a mediator between observable animal behaviors and visitor meaning-making. Implications are discussed in relation to achieving both conservation education and animal welfare outcomes. 相似文献

Most people living with HIV/AIDS (PLWHA) take steps to protect their sexual partners. However, a minority of PLWHA continue to engage in sexual risk behaviors that might contribute to the transmission of HIV. Psychiatric conditions, including certain pathological traits, are associated with sexual risk behaviors. Research examining the association between narcissistic traits as they relate to HIV transmission risk is limited. In the present study, 303 PLWHA were recruited from an infectious disease clinic and completed questionnaires assessing narcissistic characteristics, substance use, sexual risk behavior, and intentions to use condoms in the future. Narcissistic traits predicted unprotected sex with partners who are HIV-negative or whose HIV status was unknown as well as lower intentions to use condoms, after controlling for demographic factors and substance use. Interventions focused on reducing the transmission of HIV should take into account associations between sexual risk behavior and narcissism. 相似文献

Structural equation modeling (SEM) is a viable multivariate tool used by communication researchers for the past quarter century. Building off Cappella (1975) as well as McPhee and Babrow (1987), this study summarizes the use of this technique from 1995–2000 in 37 communication‐based academic journals. We identify and critically assess 3 unique methods for testing structural relationships via SEM in terms of the specification, estimation, and evaluation of their respective structural equation models. We provide general guidelines for the use of SEM and make recommendations concerning latent variable models, sample size, reporting parameter estimates, model fit statistics, cross‐sectional data, univariate normality, cross‐validation, nonrecursive modeling, and the decomposition of effects (direct, indirect, and total). 相似文献

How does the brain carry out working memory storage, categorization, and voluntary performance of event sequences? The LIST PARSE neural model proposes an answer that unifies the explanation of cognitive, neurophysiological, and anatomical data. It quantitatively simulates human cognitive data about immediate serial recall and free recall, and monkey neurophysiological data from the prefrontal cortex obtained during sequential sensory-motor imitation and planned performance. The model clarifies why spatial and non-spatial working memories share the same type of circuit design. It proposes how laminar circuits of lateral prefrontal cortex carry out working memory storage of event sequences within layers 6 and 4, how these event sequences are unitized through learning into list chunks within layer 2/3, and how these stored sequences can be recalled at variable rates that are under volitional control by the basal ganglia. These laminar prefrontal circuits are variations of visual cortical circuits that explained data about how the brain sees. These examples from visual and prefrontal cortex illustrate how laminar neocortex can represent both spatial and temporal information, and open the way towards understanding how other behaviors derive from shared laminar neocortical designs. 相似文献

A prospective analysis of acceptance of pain and values-based action in patients with chronic pain. 总被引:1,自引:0,他引:1
OBJECTIVE: Acceptance of pain and values-based action appear important in the emotional, physical, and social functioning of individuals with chronic pain. The purpose of the current study was to prospectively investigate these combined processes. METHOD: 115 patients attending an assessment and treatment course for chronic pain in the U.K. completed a standard set of measures on two occasions separated by an average of 18.5 weeks. RESULTS: Correlation analyses showed that acceptance of pain and values-based action measured at Time 1 were significantly correlated with pain, pain-related distress, pain-related anxiety and avoidance, depression, depression-related interference with functioning, and physical and psychosocial disability measured at Time 2. Multiple regression analyses, in which pain and relevant patient background variables were controlled, showed that the combined acceptance and values measures accounted for between 6.5% and 27.0% of variance in six key measures of patient functioning later in time. CONCLUSION: These results support the importance of acceptance and values-related processes in relation to chronic pain. These results also encourage continued applications of a functional contextual model of psychopathology, the model underlying Acceptance and Commitment Therapy and related approaches such as Contextual Cognitive-Behavioral Therapy. 相似文献

In this article, we present an analysis of defeasible generalizations – generalizations which are essentially exception-laden, yet genuinely explanatory – in terms of various notions of privileged conditions. We argue that any plausible epistemology must make essential use of defeasible generalizations so understood. We also consider the epistemic significance of the sort of understanding of context that is required for understanding of explanatory defeasible generalizations on any topic. 相似文献

Few studies have assessed the underlying theoretical components of the Common Sense Model. Past studies have found, through implicit priming, that coping strategies are embedded within illness schema. Our aim was to evaluate the effect priming ‘headache’ illness schema upon attentional engagement to pain relief medication and to examine the interaction with illness treatment beliefs. Attentional engagement to the pain relief medication (‘Paracetamol’) was assessed using a 2 (primed vs. control) × 2 (strong belief in medication efficacy vs. weak belief in medication efficacy) design. During a grammatical decision task (identifying verbs/non-verbs), participants were randomised to receive a headache prime or a control. Response latency to the target word, ‘Paracetamol’ was the dependent variable. ‘Paracetamol’ treatment beliefs were determined using the brief illness perception questionnaire. Sixty-three participants completed the experiment. There was a significant interaction between illness-primed vs. control and high vs. low treatment efficacy of Paracetamol (p < .001), suggesting an attentional disengagement effect to the coping strategy in illness-primed participants whom held stronger treatment beliefs regarding the efficacy of Paracetamol. In summary, implicit illness schema activation may simultaneously activate embedded coping strategies, which appears to be moderated by specific illness beliefs. 相似文献

The purpose of this study was to develop an accurate metabolic equation for estimating steady-state oxygen consumption (VO2) during submaximal NuStep exercise. Adults (N = 40; M age = 64.0 yr., SD = 6.5; M height = 170.1 cm, SD = 9.1; M weight = 85.7 kg, SD = 19.9) performed two randomized testing sessions. Each session consisted of six stages with combinations of four workloads (1, 3, 5, and 7) at 3 cadences (60, 80, and 100 steps/min.). Multiple regression analysis to predict steady-state VO2 from NuStep workload (W), NuStep steps/min., and subject body mass resulted in the following model (R2 = .73): Steady-state VO2 = 3.5 + 0.016 (W* steps/min.) + 0.092 (steps/min.) - 0.053 (weight). The standard error of the estimate and total error for the prediction of steady-state VO2 under all NuStep workload conditions were 2.3 mL/kg/min. and 2.4 mL/kg/ min., respectively. The standard error of the estimate and total error values are similar to those previously reported in the literature regarding the accuracy of metabolic equations for other exercise modalities. These findings support the use of the equation developed to predict steady-state VO2 for NuStep exercise in older adult clientele. 相似文献

Objective: An enhanced stress and coping model was used to explain depression among HIV‐positive women in healthcare and community settings where highly active anti‐retroviral treatment (HAART) was commonplace. Method: HIV‐infected women in four cities (N=978) were assessed, cross‐sectionally, for mental and physical health, stress, social support, and other background factors. Results: Self‐reported level of depressive symptomatology was high. Number of physical symptoms, illness intrusiveness, and perceived stress were positively associated with depressed mood, while coping self‐efficacy and social support were negatively associated. Stress mediated the effect of health status on depression and coping self‐efficacy mediated the effect of psychosocial resources on depression. Our enhanced stress and coping model accounted for 52% of variance in depressive symtpomatology. Conclusions: Interventions focused on improving coping self‐efficacy, bolstering social supports, and decreasing stress in the lives of HIV‐positive women may help to reduce the negative effects of HIV disease on mood. 相似文献
