Fostering house mice onto rats and deer mice: Effects on response to species odors

Newborn wild house mice (Mus musculus) were fostered upon maternal conspecifics, prairie deer mice (Peromyscus maniculatus bairdi) or laboratory rats (Rattus norvegicus). Male subjects were weaned into individual cages, in which they remained until testing commenced. At 35 days of age, subjects were given a four-choice test in which they had the opportunity to investigate tunnels scented with clean wood chips or with chips soiled by an adult male conspecific, deer mouse or rat. Compared to theMus-nursed andPeromyscus-nursed mice,Rattus-nursed mice were more active during the test and less reluctant to investigate theRattus-scented tunnel. These results were replicated in a two-choice test (Mus- vs.Rattus-scented tunnels) that included a group of mice fostered onto conspecifics, but withRattus scents present in the maternity cage throughout the nursing period. Early exposure to the scent ofRattus had no significant effects on the responses ofMus-nursed mice to the scent ofRattus.     

Different odors in rats from large and small rewards

Although rats emit different odors in a goalbox upon receipt of unsignaled reward and nonreward, recent studies have failed to find odor differences from unsignaled large and small reward, apparently disconfirming the generalization that frustration-producing manipulations lead to a distinctive emission. Experiment 1 tested the hypothesis that providing discriminative runway signals, permitting subjects to anticipate the large and small rewards, would lead to different odor emissions. Results supported the hypothesis: donor rats emitted odors sufficiently different to provide cues for differential responding in test subjects. However, an attempt to replicate the recent observations on unsignaled rewards suggested that these, too, occasioned goalbox emissions. Therefore, Experiment 2 again gave donors unsignaled large and small reward, but increased the incentive for discrimination in test rats. Test subjects readily discriminated, confirming the conclusion that large and small rewards occasion different emissions even without discriminative signals and supporting a frustration-odor interpretation.     

Aversive and aggression-promoting properties of urine from dominant and subordinate male mice

The urine of individual dominant and subordinate male mice was tested for aversive and aggression-promoting properties using open-field and aggression tests The results indicate the presence of (1) an aversive factor in male mouse urine which discourages investigation of an area marked with such urine and (2) an aggression-promoting factor. Dominant male urine proved far more effective in both respects than subordinate urine, the latter having similar effects to water. The results are discussed in terms of androgen output and possible territorial functions.

Are there constraints on learned responses to odors from rewarded and nonrewarded rats?

This study determined if test rats could utilize biological odors, generated from donor rats receiving reward (R) and frustrative nonreward (N) treatments, to predict reward and nonreward goal events equally well. In Phase 1, two groups of test rats were exposed to R and N odors that signaled, respectively, either R and N goal events (“same” condition) or N and R goal events (“opposite” condition). Rats demonstrated significant discriminative use of these odors under both conditions. Subjects in the “opposite” condition, however, were slightly slower to learn the discrimination. Reversal learning was readily accomplished in Phase 2, regardless of the same-opposite factor. Thus, little evidence for a constraint on learning was found, and an interpretation in terms of interfering response tendencies and their habituation seemed favored.

Recovery from sexual satiety in male rats

In order to describe more completely the time course of recovery from sexual satiety in male rats, 18 males were tested after each of six recovery intervals: 3, 6, 9, 11, 13, and 15 days. Different recovery rates were found for different measures of behavior. While most measures were restored to baseline levels by 6 days following satiation, the postejaculatory interval following the second ejaculation was still prolonged after 9 days of rest. No changes were seen in the number of intromissions preceding ejaculation. Systematic changes over the course of the experiment were found in the measures of copulatory behavior taken in the sessions that preceded each recovery test.

五四以来女性叙述声音的嬗变

美国后现代叙事理论家苏珊·S．兰瑟在对西方女性作家的小说文本分析基础上提出了三种叙述声音：作者型叙述声音、私人型叙述声音和集体型叙述声音。通过考察中国五四时代以来的女性作家小说文本,发现这三种叙述声音的特征对它们同样适用。在西方理论和中国文本相互观照的基础上,发现中国女性的叙述声音经过了一个由不自觉的隐匿（他者赋权）、自觉的显现（自我赋权）到与人物的声音交融（相互赋权）的过程,体现了中国女性作家书写的逐步成熟。
