Fetal and infant rats can learn to avoid odors paired with illness before development of brain areas supporting this learning in adults, suggesting an alternate learning circuit. Here we begin to document the transition from the infant to adult neural circuit underlying odor-malaise avoidance learning using LiCl (0.3 M; 1% of body weight, ip) and a 30-min peppermint-odor exposure. Conditioning groups included: Paired odor-LiCl, Paired odor-LiCl-Nursing, LiCl, and odor-saline. Results showed that Paired LiCl-odor conditioning induced a learned odor aversion in postnatal day (PN) 7, 12, and 23 pups. Odor-LiCl Paired Nursing induced a learned odor preference in PN7 and PN12 pups but blocked learning in PN23 pups. 14C 2-deoxyglucose (2-DG) autoradiography indicated enhanced olfactory bulb activity in PN7 and PN12 pups with odor preference and avoidance learning. The odor aversion in weanling aged (PN23) pups resulted in enhanced amygdala activity in Paired odor-LiCl pups, but not if they were nursing. Thus, the neural circuit supporting malaise-induced aversions changes over development, indicating that similar infant and adult-learned behaviors may have distinct neural circuits. 相似文献

The Fechner wheel is a disk that is printed in black and white. When the Fechner wheel spins at an appropriate speed, semicircles
on the wheel appear to be in color. Modern computer technology makes it possible to rapidly and repeatedly present a series
of images on a monitor screen. A series of still images of a Fechner wheel can be substituted for a Fechner wheel on a motor
shaft. Straight lines and lines of text can be substituted for semicircles to obtain a color effect. A color effect can be
obtained in small areas of black-and-white pictures. 相似文献

General catastrophic thinking styles about uncomfortable bodily sensations may predispose the development of common health pathologies, such as persistent headache. The purpose of this research was to explore the relationships between the Pain Catastrophizing (PC) Scale and Anxiety Sensitivity (AS) Index, which measure tendencies to catastrophize pain- and anxiety-related somatic sensations, respectively. A non-clinical sample completed the PC Scale, AS Index, and health outcome questionnaires regarding headache (n = 1018). Results revealed that: (i) AS and PC are empirically separate constructs; (ii) the overlap between PC and AS lies within the domain of fearing physical catastrophe; (iii) AS independently predicts weekly headache, headache pain intensity, and the number of a wide range of physical symptoms associated with headache; and (iv) PC independently predicts the presence of weekly headache. Limitations and implications of this research, as well as recommendations for future research directions are discussed. 相似文献

A hybrid efficacy-effectiveness design in which participants (n = 91/93) were retained in the study regardless of whether or not they received treatment enabled evaluation of CBT intensity in relation to panic disorder in the primary care setting. CBT intensity was operationalized as number of cognitive-behavioral therapy sessions, number of follow-up booster phone calls, and secondarily, as number of cognitive behavioral coping and exposure strategies. Baseline psychosocial and demographic predictors of CBT intensity were analyzed first. Severity of anxiety sensitivity predicted number of cognitive behavioral sessions, but no baseline variables predicted number of follow-up booster phone calls or number of coping and exposure strategies. Multivariate logistic and linear regressions were used to evaluate the degree to which treatment intensity predicted 3-month and 12-month outcomes (anxiety sensitivity, phobic avoidance, depressive symptoms, disability, and medical and mental health functioning) after controlling for potential confounding baseline variables. Number of cognitive behavioral therapy sessions predicted lower anxiety sensitivity at 3 and 12 months, and number of follow-up booster phone calls predicted lower anxiety sensitivity, less phobic avoidance, and less depression at 12 months. These findings indicate that "dose" of psychotherapy was an important predictor of outcome. The significance of follow-up booster phone contact is discussed as an index of continued self-management of panic and anxiety following acute treatment. 相似文献

In this paper we introduce a comprehensive database of the vocabulary in reading materials used by 5 – 9 year old children in the UK. The database is available on‐line http:www.essex.ac.ukpsychologycpwd and allows researchers into early reading development the possibility of rigorous control over critical characteristics of experimental stimuli such as word frequency, regularity and length, frequency of grapheme‐phoneme correspondences, orthographic and phonological neighbourhoods etc. The on‐line database is also a resource that can be used by practitioners with interests in literacy development and literacy instruction. It can be used to obtain characteristics for a user‐generated list of words, or else to generate a list of words according to constraints specified by the user. Here we present an overview of the construction of the database, the materials entered into it, the survey of schools by which we obtained information about the books that were most likely to be used by children in each age group, and the search features available on the database website. We also discuss certain characteristics of the Vocabulary itself and compare these with those reported in an earlier non‐representative database reported in Stuart, Dixon, Masterson and Gray (2003). We then present a detailed analysis of the characteristics of Vocabulary in books used in the Reception year, against the background of recent recommendations for change in the early teaching of reading. Finally, we present data showing that the database is indeed already proving a useful resource for both practitioners and researchers. 相似文献

Drawing upon expectancy value, hope, and self-determination theories, this study explores the contributions of work-based beliefs and autonomy support as predictors of adaptive achievement-related beliefs. Two hundred and one urban high school students who were enrolled in a work-based learning program completed measures of work hope, autonomy support, and achievement beliefs. Results from the full canonical correlation model revealed that work hope, career planning, and autonomy support shared 37.5% of the variance with achievement-related beliefs. Moreover, work hope and teacher autonomy support further contributed unique variance in explaining these beliefs. The findings contribute to the theoretical knowledge base concerning the value of work-based learning in fostering academic motivation among adolescents. 相似文献

Using data from the Health and Retirement Study, I examine the relationship between adult mortality and religious affiliation. I test whether mortality differences associated with religious affiliation can be attributed to differences in socioeconomic status (years of education and household wealth), attendance at religious services, or health behaviors, particularly cigarette and alcohol consumption. A baseline report of attendance at religious services is used to avoid confounding effects of deteriorating health. Socioeconomic status explains some but not all of the mortality difference. While Catholics, Evangelical Protestants, and Black Protestants benefit from favorable attendance patterns, attendance (or lack of) at services explains much of the higher mortality of those with no religious preference. Health behaviors do not mediate the relationship between mortality and religion, except among Evangelical Protestants. Not only does religion matter, but studies examining the effect of "religiosity" need to consider differences by religious affiliation. 相似文献

This qualitative study compiled input from employers (N = 7) participating in a program geared to prepare high school students with emotional disturbances for post‐high‐school employment situations. Data were collected through open‐ended interviews related to 4 research questions and analyzed through thematic and comparative analysis. Results showed a link between the skills employers desired from their employees and skills needed for students with emotional disturbances to be successful. Employers' recommendations included measures to address prior to program implementation and ways to create strong support systems for students with disabilities. 相似文献
