Three experiments were conducted with adult male Meriones unguiculatus in an attempt to demonstrate that ventral scent marking can act to transfer body heat to the object marked. Experiment 1 showed that surgical removal of the ventral gland pad reduced the amount of heat transferred by 50%, even though intact and glandless animals did not differ in the average frequency of scent marking. Experiment 2 demonstrated that the difference in heat transfer due to the presence or absence of the scent pad was not due to differential pressure applied to the substrate during marking. Experiment 3 showed that the pattern of ventral hair spread that occurs as an animal moves over an object is different between intact and glandless animals but that this difference does not account for the difference in heat transfer. It is suggested that heat transfer to the environment with ventral scent marking may increase thermoregulatory competence and also may function to volatilize sebum used in chemocommunication. 相似文献

Very few behavioral patterns generalize across human and nonhuman species. We describe washing, drying, and anointing sequences in humans (Homo sapiens) that may have analogies with other species. The rank ordering of washing, drying, and anointing body parts was obtained over 3 successive days for 37 men and 60 women. Variation in rank ordering of body parts was nonrandom, and a cephalocaudal progression was evident for each behavior. Reliability of the behaviors as well as the correlations across rankings were highly significant, which indicates a generalized cephalocaudal progression for all 3 behaviors. Women's anointing was most variable, which suggests a more specific function. The cephalocaudal action pattern described for humans is similar to that for Mongolian gerbils and laboratory rats. Cross-species functions, such as these, may add to our understanding of common developmental and learning processes. 相似文献

For both adults and children, acoustic context plays an important role in speech perception. For adults, both speech and nonspeech acoustic contexts influence perception of subsequent speech items, consistent with the argument that effects of context are due to domain-general auditory processes. However, prior research examining the effects of context on children’s speech perception have focused on speech contexts; nonspeech contexts have not been explored previously. To better understand the developmental progression of children’s use of contexts in speech perception and the mechanisms underlying that development, we created a novel experimental paradigm testing 5-year-old children’s speech perception in several acoustic contexts. The results demonstrated that nonspeech context influences children’s speech perception, consistent with claims that context effects arise from general auditory system properties rather than speech-specific mechanisms. This supports theoretical accounts of language development suggesting that domain-general processes play a role across the lifespan. 相似文献

Adult gerbils, Meriones unguiculatus, autogroom their body parts in the order: mouth--nose, face, ears, flank, ventrum, and tail. This is the identical order in which the autogroom matures during the first 33 days of life. The parallel sequencing increases our understanding of neurophysiological processes underlying movement patterns and also indicates how movement patterns evolve. 相似文献

A glass housing unit for the study of rodent burrowing behavior is described. The results of 18 months of burrowing for a family ofMeriones unguiculatus are depicted. The system can be used to investigate relationships among the animals’ behaviors, communication processes, and ecology. 相似文献

Three experiments were conducted to explore the effects of first names on judgments of intelligence, popularity, and competence. In Experiment 1, first names that were used more often in the past than they are now (called Older Generation names) were rated by a sample of college-aged judges as less popular and less intelligent than were first names that are used more often now than in the past (called Younger Generation names). In addition, male first names tended to have higher ratings of these same qualities than did female first names. In Experiments 2 and 3, either resumes or personal ads were used to provide additional information to the raters. Results similar to those found in Experiment 1 were obtained. In general the present experiment used groups of names rather than individual names so as to control for possible irrelevant and idiosyncratic differences that might be found among individual names. Relevance to research in which men and women are compared was discussed. 相似文献
