After 12-15 ejaculatory series, each consisting of several short intromissions (2- to 3-s vaginal penetration) and an ejaculation, male golden hamsters adopt an altered copulatory pattern consisting of long intromissions (5- to 25-s penetration with intravaginal thrusting). Receptivity declines and the tendency for the female to attack the male increases at about the time of this shift in copulatory pattern. Because the mean interintromission interval (III) between short intromissions is about 8 s compared to 100 s between long intromissions, it is possible that females detect this difference and adjust their mating accordingly. When the III between short intromissions from a rested male was experimentally increased to 100 s by use of a halter and lead device, the duration of lordosis was significantly less than that displayed by females paired with control males (8-s III) and virtually the same as that displayed by females paired with males that produced only long intromissions. This suggests that the female uses the temporal patterning of intravaginal stimulation as one criterion for terminating mating with a particular male.  相似文献

Three groups of rats were exposed to pairs of three different contingencies on two sides of a shuttlebox. One signaled contingency provided 10-min danger and safety cues plus an additional 10-sec cue immediately preceeding shock (P-S), another signaled contingency provided 10-min danger and safety cues but random 10-sec cues with respect to shock (R-S), and an unsignaled contingency provided no safety period, but only a 20-min danger period during which shock could occur (NS). Signaled P-S and R-S contingencies were preferred in a choice test to the unsignaled NS contingency, and P-S was preferred to R-S. Independent tests of the fear-eliciting properties of the cues made in an off-baseline test of suppression of ongoing exploration indicated more freezing (fear) to the 10-sec cue in rats experiencing the P-S contingency. The results were interpreted as indicating a preference for cues providing more precise information about the temporal location of shock even when those cues were fear-eliciting.  相似文献

Low-income families are more likely to have a child with an early-onset Behavior Disorder (BD); yet, socioeconomic strain challenges engagement in Behavioral Parent Training (BPT). This study follows a promising pilot to further examine the potential to cost-effectively improve low-income families’ engagement in and the efficiency of BPT. Low-income families were randomized to (a) Helping the Noncompliant Child (HNC; McMahon & Forehand, 2003), a weekly, mastery-based BPT program that includes both the parent and child or (b) Technology-Enhanced HNC (TE-HNC), which includes all of the standard HNC components plus a parent mobile application and therapist web portal that provide between-session monitoring, modeling, and coaching of parent skill use with the goal of improved engagement in the context of financial strain. Relative to HNC, TE-HNC families had greater homework compliance and mid-week call participation. TE-HNC completers also required fewer weeks to achieve skill mastery and, in turn, to complete treatment than those in HNC without compromising parent satisfaction with treatment; yet, session attendance and completion were not different between groups. Future directions and clinical implications are discussed.  相似文献

This article begins by summarizing the concept of ethical apophaticism in the theology of John Zizioulas and Christos Yannaras. The impetus for this concept, namely a desire to maintain the irreducibility of the human person to extrinsic ethical categories, is noted and celebrated. However, it is proposed that to do fuller justice to the understanding of the ethical and moral life in the Orthodox tradition, a certain ‘ethical cataphaticsm’ needs to be brought into the discussion. Some potential lineaments of what this might entail for these authors are highlighted (repentance and love) before seeking to supplement them with a discussion of the commandments of Christ through the lens of the theology of Sophrony Sakharov. It is argued that Christ’s commandments provide the sure path to developing an ethical cataphaticism that can work in tandem with the insights of the category of ethical apophaticism offered by Zizioulas and Yannaras.  相似文献

The purpose of this study was to explore potential differences between Asian and non-Asian university students in attitudes toward coercive and noncoercive sexual behavior. Four hundred women and men (205 Asian, 195 non-Asian) were assessed on attitudes towards rape, sexual harassment, and general sexual behavior. Length of residency in Canada for Asian respondents was examined to determine whether Westernization might attenuate differences. Analysis revealed that Asian students were significantly more conservative in attitudes toward sexual behavior. Asian students were also more tolerant of rape myths and more accepting of sexual harassment. Asian respondents demonstrated a decrease in tolerance for rape myths and sexual harassment as length of residency in Canada increased. Women were less conservative than men from the same background on almost all items.  相似文献

This study randomly assigned participants to either an aerobic, non-aerobic, or lecture group to assess whether one bout of exercise would alter mood state. Regardless of experimental condition, changes in mood state were found on the Sensation Seeking and Anxiety State Tests, where sensation-seeking scores increased and anxiety state decreased from pre- to posttest.  相似文献

Tooth whitening has become a very popular procedure. Advertisements for whitening products imply that whiter teeth are more attractive than yellower teeth. We tested this idea empirically by manipulating the tooth color of pictures of male and female targets. Participants' ratings of attractiveness were not influenced by tooth color. Exp. 2 yielded a negative correlation between attractiveness and age ratings: targets judged to be older were rated as less attractive. Unless whiter teeth help in some other way, e.g., improved self-esteem or confidence, it seems that tooth whitening procedures or products are not associated with increased attractiveness to others.  相似文献
