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

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

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

In this study, the validity of the recently developed 28-item Resilience Scale for Adolescents (READ) was examined. Survey
data from a representative sample of 6,723 Norwegian senior high school students between 18 and 20 years of age were used
for this purpose. Validity and reliability were investigated by means of exploratory and confirmatory factor analysis, correlations
with other relevant variables, and internal consistency measures. The results supported the construct and convergent validity
of the five factors of a modified 23-item version of the scale, which also yielded acceptable psychometric properties. The
paper concludes that the modified READ is a valid measure assessing relevant resilience factors with relatively few items,
thereby serving as a valuable tool in resilience and risk-factor research. 相似文献

Parents who came with their child to Child and Adolescent Psychiatry (CAP) for the first time were interviewed 1–2 weeks afterwards
in the presence of the child and the therapists. In a grounded theory analysis they revealed uncertainty about their role
in the first meeting as well as of future planning. What had been important to them were aspects like communication, sharing
perspectives, and the reformulation of problems. 相似文献

Gricean communication is communication between utterers and their audiences, where the utterer means something and the audience
understands what is meant. The weak transmission idea is that, whenever such communication takes place, there is something
which is transmitted from utterer to audience; the strong transmission idea adds that what is transmitted is nothing else
than what is communicated. We try to salvage these ideas from a seemingly forceful attack by Wayne Davis. Davis attaches too
much significance to the surface structure of sentences of the type ‘S communicates the belief (desire …) that p to A’ by assuming that the communicated entity is denoted by the grammatical object following ‘communicates’. On our proposal,
what is communicated in all Gricean cases is a thought. And since S communicates the thought that p to A only if S means that p and A understands what S means, the thought that p will be transmitted from S to A. 相似文献

The article reports a systematic review of controlled outcome evaluations of psychosocial and organic sexual offender treatment. A comprehensive search of the literature in five languages revealed 80 independent comparisons between treated and untreated groups of sexual offenders ( N = 22,181). The majority of studies confirmed a positive treatment effect. Overall, 11.1% of treated offenders and 17.5% of controls showed sexual recidivism (37% difference). Findings for violent and general recidivism were similar. Studies on surgical castration showed the strongest effect; however, this was confounded with methodological and offender characteristics. Hormonal medication, cognitive-behavioural, and behavioural approaches also revealed a positive effect. Non-behavioural treatments did not show a significant impact. Other moderators such as small sample size, authors' affiliation with the program, program completion versus dropout, or type of outcome measure had a significant impact. Methodological study characteristics explained the largest proportion of effect size variance. Overall, findings are promising but more differentiated evaluations of high quality are needed. 相似文献
