Sexual dimorphism in ultrasonic vocalizations of mice (Mus musculus): gonadal hormone regulation 总被引:1,自引:0,他引:1

Male mice (Mus musculus), during courtship and sexual behavior, vocalize substantially more 70-kHz ultrasounds than do females. Four experiments demonstrated that testosterone propionate (TP) substantially increased ultrasonic emissions and mounting by ovariectomized females and the long-term gonadectomized males and females increased their amount of ultrasound production in response to TP to approximately the same levels. From these results it is suggested that the sexual dimorphism normally seen in ultrasonic vocalizations can be accounted for by the activational effects of androgen in adulthood. 相似文献

Ultrasonic vocalizing by adult female mice (Mus musculus) 总被引:3,自引:0,他引:3
J C Maggio G Whitney 《Journal of comparative psychology (Washington, D.C. : 1983)》1985,99(4):420-436
Though an extensive body of literature exists concerning the emission of 70-kHz ultrasonic vocalizations by adult male mice (Mus musculus), almost nothing is known about the ultrasonic vocalizing of adult females. A series of five experiments was conducted to examine adult female mouse ultrasound emission. Results indicated female ultrasonic vocalizing to be typically displayed among female mouse dyads and comparable to the ultrasonic vocalizing levels obtained among male-female pairs. Genotypically based variations in the production of ultrasounds by females were also noted. Like male mice, socially naive females readily ultrasonically vocalized to anesthetized female conspecifics and rarely vocalized to anesthetized males. Unlike males, socially experienced females emitted few ultrasounds to either female urine or female-soiled cage shavings. Although social experience served to increase the ultrasound emission of male mice to female sex cues, the production of ultrasounds by females to these cues was decreased by social experience. Implications with regard to the existence of a behavioral/functional sexual dimorphism in adult mouse ultrasonic vocalizing are discussed. 相似文献

Acetaldehyde poisoning from ethanol ingestion may lead to aversion to ethanol among DBA mice but not among C57s, since the former are relatively deficient in aldehyde dehydrogenase activity. The present study paired ingestion of saccharin with a single intraperitoneal injection of one of four concentrations of ethanol for DBA/2J and C57BL/6J mice. Subjects were then given a two-bottle saccharin versus water preference test for 10 days. Substitution of saccharin for the taste of ethanol resulted in avoidance of saccharin with all concentrations of ethanol by DBAs but not by C57s, consistent with the conditioned taste aversion paradigm as a model for genetically mediated ethanol avoidance. 相似文献

This research extends previous attempts to determine whether subjects make predictive inferences during comprehension. For example, when subjects read a passage about someone falling out of a 14th-story window, do they infer that the person is dead? Previous research in which lexical decision, word naming, and recognition tasks have been used for detecting predictive inferences has had mixed results. In experiment 1, a word-stem completion task was used to test for predictive inferences. The word stems were formed from target inferences that followed either priming or control passages. The data revealed that predictive inferences are generated only about concepts that are foregrounded in the passages. In Experiments 2 and 3, lexical decision and naming were used to test for predictive inferences. The lexical decision data replicated the word-stem completion data. A control experiment ruled out a simple context-checking explanation for the lexical decision results. The naming data indicated that this tasks was not sensitive to elaborative inference generation. Theresults show that readers make predictive inferences, but do so selectively. 相似文献

Individuals can quickly and effortlessly recognize facial expressions, which is critical for social perception and emotion regulation. This sensitivity to even slight facial changes could result in unstable percepts of an individual’s expression over time. The visual system must therefore balance accuracy with maintaining perceptual stability. However, previous research has focused on our sensitivity to changing expressions, and the mechanism behind expression stability remains an open question. Recent results demonstrate that perception of facial identity is systematically biased toward recently seen visual input. This positive perceptual pull, or serial dependence, may help stabilize perceived expression. To test this, observers judged random facial expression morphs ranging from happy to sad to angry. We found a pull in perceived expression toward previously seen expressions, but only when the 1-back and current face had similar identities. Our results are consistent with the existence of the continuity field for expression, a specialized mechanism that promotes the stability of emotion perception, which could help facilitate social interactions and emotion regulation. 相似文献

The goal of this study was to explore the ability to discriminate languages using the visual correlates of speech (i.e., speech-reading). Participants were presented with silent video clips of an actor pronouncing two sentences (in Catalan and/or Spanish) and were asked to judge whether the sentences were in the same language or in different languages. Our results established that Spanish-Catalan bilingual speakers could discriminate running speech from their two languages on the basis of visual cues alone (Experiment 1). However, we found that this ability was critically restricted by linguistic experience, since Italian and English speakers who were unfamiliar with the test languages could not successfully discriminate the stimuli (Experiment 2). A test of Spanish monolingual speakers revealed that knowledge of only one of the two test languages was sufficient to achieve the discrimination, although at a lower level of accuracy than that seen in bilingual speakers (Experiment 3). Finally, we evaluated the ability to identify the language by speech-reading particularly distinctive words (Experiment 4). The results obtained are in accord with recent proposals arguing that the visual speech signal is rich in informational content, above and beyond what traditional accounts based solely on visemic confusion matrices would predict. 相似文献

The Mini-Mental State Examination (MMSE) and the Peabody Picture Vocabulary Test, Third Edition (PPVT-III) were administered to 76 Extended Care Center inpatients of a Veterans Affairs Medical Center, 56 of whom did not carry a diagnosis associated with brain impairment, and 20 of whom had a diagnosis associated with degenerative or cerebrovascular conditions. MMSE and PPVT-III scores, the latter of which estimates verbal IQ, were significantly correlated in both groups, even when controlling for the effects of education. This correlation was attenuated, but remained significant, in the face of varying levels of patient effort. The findings of this study support earlier findings, which also suggest that interpretation of "impaired" performance on the MMSE for those with IQ scores below 90 should be interpreted with caution. Average MMSE scores for Wechsler IQ classifications are provided. 相似文献

The loss of a spouse is associated with a host of negative health outcomes. While bereaved individuals commonly report somatic symptoms, no investigations exist of the association between reactivation of latent Epstein–Barr virus (EBV) and somatic symptoms among this population. Further, how an individual perceives the quality of their lost relationship in retrospect may impact loss outcomes. Among 99 bereaved spouses, elevated EBV antibody titers were associated with somatic symptoms for those who retrospectively reported high or mean levels of relationship satisfaction (RS), but not among those less satisfied. Further, higher RS was associated with greater grief symptoms. This study identifies higher retrospective RS as a possible risk factor for negative physical and mental health outcomes during bereavement. 相似文献

Borderline personality disorder (BPD) is a pervasive pattern of psychopathology characterized by unstable affect, suicidal behaviors, and identity problems (Diagnostic and statistical manual of mental disorders. Washington, DC: Author; 2000). BPD is heterogeneous in nature, highly prevalent in clinical settings, and increasingly studied by clinical and social psychologists. This review highlights affective instability, impulsivity, and interpersonal hypersensitivity, the interaction of which we believe accounts for the symptoms of BPD, the BPD criteria most associated with these features, and the interrelationships among these underlying dimensions. We also discuss difficulties in measurement of these dimensions. Real-world assessment methods will assist in the measurement of time-dependent processes and identify causes, covariates, or consequences of these processes to determine how these features manifest themselves in real life. 相似文献
