Drosophila larvae combine a numerically simple brain, a correspondingly moderate behavioral complexity, and the availability of a rich toolbox for transgenic manipulation. This makes them attractive as a study case when trying to achieve a circuit-level understanding of behavior organization. From a series of behavioral experiments, we suggest a circuitry of chemosensory processing, odor-tastant memory trace formation, and the "decision" process to behaviorally express these memory traces--or not. The model incorporates statements about the neuronal organization of innate vs. conditioned chemosensory behavior, and the types of interaction between olfactory and gustatory pathways during the establishment as well as the behavioral expression of odor-tastant memory traces. It in particular suggests that innate olfactory behavior is responsive in nature, whereas conditioned olfactory behavior is captured better when seen as an action in pursuit of its outcome. It incorporates the available neuroanatomical and behavioral data and thus should be useful as scaffold for the ongoing investigations of the chemo-behavioral system in larval Drosophila. 相似文献

Cognitive neuroscientists study how the brain implements particular cognitive processes such as perception, learning, and decision-making. Traditional approaches in which experiments are designed to target a specific cognitive process have been supplemented by two recent innovations. First, formal cognitive models can decompose observed behavioral data into multiple latent cognitive processes, allowing brain measurements to be associated with a particular cognitive process more precisely and more confidently. Second, cognitive neuroscience can provide additional data to inform the development of formal cognitive models, providing greater constraint than behavioral data alone. We argue that these fields are mutually dependent; not only can models guide neuroscientific endeavors, but understanding neural mechanisms can provide key insights into formal models of cognition. 相似文献

The present field experiment examined how multi-trial visuo-spatial learning and memory performance are impacted by excessive
arousal, instigated by a potentially life-threatening event (i.e., a first parachute jump). Throughout a parachute training
activity, subjective and neuroendocrine (i.e., cortisol) stress levels were assessed of 61 male military cadets who were randomly
assigned to a control (n = 30) or a jump stress condition (n = 31). Post-stress learning and memory capacity was assessed with a 10-trial path-learning task that permitted emergence
of learning curves. Pre-activity cortisol concentrations indicated a significant neuroendocrine anticipatory stress response
in the stress group. Following parachuting, subjective stress levels and salivary cortisol reactivity differed significantly
between groups. Visuo-spatial path-learning performance was impaired significantly after jump stress exposure, relative to
the control group. Moreover, examination of the learning curves showed similar learning and memory performance at onset of
the trials, with curves bifurcating as the task became more complex. These findings are in accordance with leading theories
that acknowledge a moderating effect of task complexity. In sum, the present study extends knowledge concerning anticipatory
stress effects, endogenously instigated cortisol reactivity, and the influence of extreme arousal on visuo-spatial path learning. 相似文献

The changing natures of both work and the lives of the U.S. workforce have created an array of challenges for organizations attempting to foster work engagement. To accommodate the work and family needs of an increasingly diverse workforce, many firms are offering flexible work solutions to employees. However, the distribution of these types of organizational resources is unequal, with workers in lower-wage hourly jobs having the least access to any form of flexibility. The purpose of this paper is to examine the relationship of schedule control, as a form of flexible work practice, and work engagement among workers employed in hourly retail jobs. Authors tested a model whereby the relationship between schedule control and work engagement is mediated by schedule satisfaction and perceived supervisor support. A sample of 1343 full-time hourly retail workers was used to address the study's purpose. Hypothesized relationships were fully or partially supported. Implications for research and practice are discussed. 相似文献

Public understanding of climate change in the United States 总被引:2,自引:0,他引:2
This article considers scientific and public understandings of climate change and addresses the following question: Why is it that while scientific evidence has accumulated to document global climate change and scientific opinion has solidified about its existence and causes, U.S. public opinion has not and has instead become more polarized? Our review supports a constructivist account of human judgment. Public understanding is affected by the inherent difficulty of understanding climate change, the mismatch between people's usual modes of understanding and the task, and, particularly in the United States, a continuing societal struggle to shape the frames and mental models people use to understand the phenomena. We conclude by discussing ways in which psychology can help to improve public understanding of climate change and link a better understanding to action.

It is still a popular philosophical position to call for a strict “separationism” concerning the private and the public sphere
when it comes to religious convictions. Richard Rorty is one prominent supporter of this claim. The traditional critique against
this division is mostly built on a particular characterization of religion that is at odds with Rortian assumptions. In this
article, however, Rorty is criticized on his own terms turning pragmatically the objection to a fully internal one. What Rorty
values most, namely a tolerant and ironic liberalism as the capacity to describe oneself in new and interesting ways is precisely
the role, I argue, that religious faith could play under “neo-liberal” conditions. 相似文献

As psychology has moved toward emphasizing evidence-based practice, use of treatment manuals has extended from research trials into clinical practice. Minimal research has directly evaluated use of manuals in clinical practice. This survey of international eating disorder professionals examined use of manuals with 259 clinicians’ most recent client with bulimia nervosa. Although evidence-based manuals for bulimia nervosa exist, only 35.9% of clinicians reported using a manual. Clinicians were more likely to use a manual if they were younger; were treating an adult client; were clinical psychologists; were involved in research related to eating disorders; and endorsed a cognitive-behavioral orientation. Clinicians were less likely to use a manual if they provided eclectic psychotherapy that incorporated multiple psychotherapeutic approaches. We conclude that psychotherapy provided in clinical practice often does not align with the specific form validated in research trials, and “eclecticism” is at odds with efforts to disseminate manuals into clinical practice. 相似文献

In a birth cohort of 6281 men from Aberdeen, Scotland, social class of origin, childhood intelligence, childhood behavior disturbance and education were examined as predictors of status attainment in midlife (46 to 51 years). Social class of origin, intelligence and behavior disturbance were conceptualized as correlated predictors, whose effects were hypothesized to be partially mediated by educational qualifications. A structural equation model using Full Information Maximum Likelihood estimation confirmed that education had the strongest direct effect on status attainment at midlife. Furthermore, education partially mediated the effects of social class of origin and childhood intelligence, and fully mediated the effects of behavior disturbance on status attainment. Social class of origin, childhood intelligence and behavior disturbance were strongly inter-correlated. After controlling for these associations, educational and social status attainments were influenced to a considerably greater extent by childhood intelligence than by social class of origin. 相似文献
