To investigate a cognitive diathesis-stress model, the present study evaluated the main and interactive effects of anxiety sensitivity (AS) and exposure to aversive conditions (past month) in predicting theoretically relevant panic vulnerability variables in an epidemiologically defined sample from Russia (N = 390). Consistent with expectation, findings suggested that the combination of high levels of exposure to aversive conditions and high AS physical concerns predicted panic attacks (past week) and agoraphobic avoidance above and beyond the variance accounted for by negative affect. These findings are discussed in relation to biopsychosocial theories of panic disorder, which emphasize the importance of both a cognitive diathesis and stress component in the pathogenesis of the disorder. 相似文献

We studied error monitoring in ADHD and control children in a task requiring inhibition of a motor response. The extent of slowing following successful (stopped) and failed (nonstopped) inhibition was compared across groups. We also measured the time required to inhibit a response (stop signal reaction time, SSRT). Compared to controls, ADHD participants slowed less following nonstopped responses. Slowing did not vary with comorbid reading, oppositional, conduct or anxiety disorder, sex or ADHD subtype. Slowing after nonstopped responses was marginally, although significantly correlated with total ADHD symptoms and with age. ADHD participants had significantly longer SSRT than controls, but SSRT was not significantly correlated with slowing. The apparent deficit in error monitoring in ADHD and its independence from the inhibition deficit observed in ADHD has implications for executive control models of ADHD, performance problems associated with the disorder and for component theories of executive control. 相似文献

The present study addresses the question of what kind of information children use when orientating in new environments, if given proximal and distal landmarks, and how spatial memory develops in the investigated age groups. Ten 5-year-old, ten 7-year-old and ten 10-year-old children were presented with the ‘Kiel Locomotor Maze’, containing features of the Radial Arm Maze and the Morris Water Maze, in order to assess spatial memory and orientation. Children had to learn to approach baited locations only. Task difficulty was equated with respect to the children's age. Training was given until the children reached criterion. During testing, the maze configuration and response requirements were systematically altered, including response rotation, cue rotation, cue deletion and response rotation with cue deletion in order to assess the spatial strategies used by the children. During training and testing, working-memory errors (WM), reference-memory errors (RM) and working-reference memory errors (WR) were recorded. As expected, no difference between age groups appeared during training, thus confirming comparable task difficulty across age groups. During testing, age groups differed significantly with regard to the orientation strategy used. The 5-year-olds were bound to a cue strategy, orientating towards local, proximal cues. The 10-year-olds mastered all tasks, thus displaying a place strategy, being able to use distal cues for orientation, and were even able to do so after being rotated 180°. The 7-year-olds proved to be at an age of transition: five of them were bound to a cue strategy, five children were able to adopt a place strategy. The differences in the orientation strategies used by children of different age groups was reflected by the sum of errors they made, also by RM. WM were found to be rare, especially in older children. We conclude that preschoolers use a cue strategy, that the development of place strategies occurs during primary school age and seems to be complete by the age of 10 years. 相似文献

Even though perceptional abilities have repeatedly been found to be associated with certain personality styles (e.g., extraversion), such connections were reported sparsely for the olfactory modality. Two studies were carried out to investigate the relationship between olfactory sensitivity and 12 personality dimensions (including extraversion and neuroticism). In the first study, single olfactory measurements were compared to repeated measurements. In the second study, twins were recruited as subjects to also examine the heredity of olfactory sensitivity. The results indicate that neuroticism is a stronger predictor for olfactory sensitivity than extraversion. Repeated measurements seem to be necessary to obtain valid data on olfactory performance. 相似文献

We have used a combined genetic and pharmacological approach to define the time course of the requirement for protein kinase A (PKA) and protein synthesis in long-term memory for contextual fear conditioning in mice. The time course of amnesia in transgenic mice that express R(AB) and have genetically reduced PKA activity in the hippocampus parallels that observed both in mice treated with inhibitors of PKA and mice treated with inhibitors of protein synthesis. This PKA- and protein synthesis-dependent memory develops between 1 hr and 3 hr after training. By injecting the protein synthesis inhibitor anisomycin or the PKA inhibitor Rp-cAMPs at various times after training, we find that depending on the nature of training, contextual memory has either one or two brief consolidation periods requiring synthesis of new proteins, and each of these also requires PKA. Weak training shows two time periods of sensitivity to inhibitors of protein synthesis and PKA, whereas stronger training exhibits only one. These studies underscore the parallel dependence of long-term contextual memory on protein synthesis and PKA and suggest that different training protocols may recruit a common signaling pathway in distinct ways. 相似文献

Locomotor activity of single, freely walking flies in small tubes is analyzed in the time domain of several hours. To assess the influence of the mushroom bodies on walking activity, three independent noninvasive methods interfering with mushroom body function are applied: chemical ablation of the mushroom body precursor cells; a mutant affecting Kenyon cell differentiation (mushroom body miniature1); and the targeted expression of the catalytic subunit of tetanus toxin in subsets of Kenyon cells. All groups of flies with mushroom body defects show an elevated level of total walking activity. This increase is attributable to the slower and less complete attenuation of activity during the experiment. Walking activity in normal and mushroom body-deficient flies is clustered in active phases (bouts) and rest periods (pauses). Neither the initiation nor the internal structure, but solely the termination of bouts seems to be affected by the mushroom body defects. How this finding relates to the well-documented role of the mushroom bodies in olfactory learning and memory remains to be understood. 相似文献

Already after sending the first two parts of this paper ([5], [6]) to the editor, two new results on the subject have appeared — namely the results of G. Wilmers and Z. Ratajczyk. So for the sake of completeness let us review them here.Allatum est die 2 Septembris 1976 相似文献

This article examines the prospects for an authentic regional architecture in the light of alternative development paradigms. It is argued that the failure of orthodox development strategies and the domination of western culture, including architecture, over non-Western cultures, is due to fundamental imbalances between northern and southern economic structures. By contrast, ecodevelopment, appropriate technology and regional architecture all represent significant devolutionary movements toward a global “eco-culture.” A cultural typology placing eco-culture in historical perspective is outlined. It is concluded that, to be fully effective, changes in development patterns in the south have to be matched by equivalent cultural changes in the North. 相似文献
