Mouse ultrasonic vocalizations (USVs) are often used as behavioral readouts of internal states, to measure effects of social and pharmacological manipulations, and for behavioral phenotyping of mouse models for neuropsychiatric and neurodegenerative disorders. However, little is known about the neurobiological mechanisms of rodent USV production. Here we discuss the available data to assess whether male mouse song behavior and the supporting brain circuits resemble those of known vocal non-learning or vocal learning species. Recent neurobiology studies have demonstrated that the mouse USV brain system includes motor cortex and striatal regions, and that the vocal motor cortex sends a direct sparse projection to the brainstem vocal motor nucleus ambiguous, a projection previously thought be unique to humans among mammals. Recent behavioral studies have reported opposing conclusions on mouse vocal plasticity, including vocal ontogeny changes in USVs over early development that might not be explained by innate maturation processes, evidence for and against a role for auditory feedback in developing and maintaining normal mouse USVs, and evidence for and against limited vocal imitation of song pitch. To reconcile these findings, we suggest that the trait of vocal learning may not be dichotomous but encompass a broad spectrum of behavioral and neural traits we call the continuum hypothesis, and that mice possess some of the traits associated with a capacity for limited vocal learning. 相似文献

One persistent challenge in scientific practice is that the structure of the world can be unstable: changes in the broader context can alter which model of a phenomenon is preferred, all without any overt signal. Scientific discovery becomes much harder when we have a moving target, and the resulting incorrect understandings of relationships in the world can have significant real-world and practical consequences. In this paper, we argue that it is common (in certain sciences) to have changes of context that lead to changes in the relationships under study, but that standard normative accounts of scientific inquiry have assumed away this problem. At the same time, we show that inference and discovery methods can “protect” themselves in various ways against this possibility by using methods with the novel methodological virtue of “diligence.” Unfortunately, this desirable virtue provably is incompatible with other desirable methodological virtues that are central to reliable inquiry. No scientific method can provide every virtue that we might want. 相似文献

Four experiments examined the effect of category cueing on recall-to-reject, one of the central memory-editing mechanisms thought to prevent the occurrence of false memories. When category names were used as retrieval cues, the typically observed false recognition effect was eliminated for semantically associated distractors (Experiment 1a) and, moreover, a reduction in the absolute level of the false alarm rate was found for phonologically associated distractors (Experiment 2a). In addition to the old/new-recognition data, analyses using multinomial models support the interpretation that category cueing was successful in increasing the probability of recall-to-reject (Experiments 1b and 2b). The results are in line with dual-process theories of recognition memory and provide further evidence for recall-to-reject in single item recognition. They demonstrate its potential to reduce false recognition even when explicit instructions are not given. In addition, the results demonstrate that the paradigm can give rise to side effects that oppose recall-to-reject. A simultaneous familiarity increase can explain why many studies failed to find evidence for recall-to-reject in terms of false alarm rates. 相似文献

Abstract We examined the impact of acute marital conflict on emotion, cardiovascular arousal, and immune function in men and women. Subjects were 10 heterosexual, distressed couples, who panicipated in exchange for marital therapy. Each couple participated in a 40 minute conflict induction regarding an area of difficulty in their relationship. During this induction, blood pressure and heart rate were monitored and blood samples were drawn pre- and post-induction for analysis of immune change. Women responded to the experimental induction with significantly greater increases in depression and hostility, and with significantly greater increases in SBP than men. Women also responded to the acute marital distress with slight decreases in lymphocyte proliferative response to PHA, while men displayed an increase in PHA response. The sex by time interaction was significant Change in PHA was associated with change in hostility and SBP. 相似文献

Relationships between individual values and preferred leadership behaviors were examined in a sample of 324 managers from organizations in Romania, a country in transition from a controlled economy to a free‐market system. We found the value dimensions of achievement, benevolence, and power to predict preferences for both transformational and transactional leadership behaviors. Specifically, achievement and benevolence displayed positive relationships with both types of leadership. In contrast, power yielded a positive relationship with the preference for transactional behaviors, but an inverse relationship with the preference for transformational leadership. The implications of these findings are discussed. 相似文献

This paper argues that we have wrongly and not for the patient’s benefit made a form of stark autonomy our highest value which
allows physicians to slip out from under their basic duty which has always been to pursue a particular patient’s good. In
general – I shall argue – it is the patient’s right to select his or her own goals and the physician’s duty to inform the
patient of the feasibility of that goal and of the means needed to attain it. If the goal is not one that is possible, the
patient, with the physician and family, must select a feasible goal and then discuss the costs/benefits of various approaches.
The physician should take a leading role in helping the patient select the goal. I argue that to simply present a laundry
list of means and insist that patients choose for themselves is not only abandoning patients to their autonomy but is, in
fact, a crass form of violating the patient’s autonomy. Freely choosing not to choose is a choice a patient with decisional
capacity is entitled to make and one that needs to be respected. 相似文献
