The Suicide Opinion Questionnaire (SOQ) was administered to two samples of medical school students, from Japan (n = 80 males and 20 females) and the United States (n = 80 males and 20 females). A MANOVA followed by univariate tests indicated significant differences on the Right to die, Normality, and Aggression scales between Japanese and United States students, and significant gender differences on the Religion and Impulsivity scales. No gender by nationality interaction was obtained. An analysis of the individual SOQ items revealed substantial differences between Japanese and United States medical students in their views on suicide. 相似文献

ABSTRACT— Little is known about neural responses in the early automatic-stage processing of rejection cues from a partner. Event-related potentials (ERPs) offer a window to study processes that may be difficult to detect via behavioral methods. We focused on the N400 ERP component, which reflects the amount of semantic processing prompted by a target. When participants were primed by attachment-related contexts ("If I need help from my partner, my partner will be …"), rejection-related words (e.g., dismissing ) elicited greater N400 amplitudes than acceptance-related words (e.g., supporting ). Analyses of results for nonattachment primes suggest that these findings were not simply caused by target valence; the brain responds differentially to cues of partner rejection (vs. acceptance) in under 300 ms. Moreover, these early-stage neurophysiological responses were heightened or dampened as a function of individuals' adult attachment; women characterized by high anxiety and low avoidance showed the greatest N400 responses to cues of partner rejection (vs. acceptance). 相似文献

Two experiments investigated the effects of humor on memory for non-sensical pictures. Each picture was given three labels that differed in the degree of humor: high, low, and no humor labels. In Experiment 1, the humor of the picture labels was manipulated between participants. Participants were shown 30 pictures for 10 s each and were asked to rate the degree of humor of each picture. After the rating task, participants were asked to draw the pictures in an unexpected memory test. Performance in the memory test was best in the high humor label group, followed by the low and the no humor label groups. In Experiment 2, intention to learn (incidental versus intentional encoding tasks) as well as humor label was manipulated between the participants. In the incidental learning condition, the high humor group performed better than the low humor group, but in the intentional learning condition, there was no humor effect. The effects of humor on picture memory were discussed in terms of appraisal processing within a distinctiveness framework. 相似文献

Removal of mystacial vibrissae for strange rats placed in an established rat colony produced reliable decrements in defensive boxing for these animals, and corresponding increases in freezing. In a subsequent experiment, removal of the vibrissae of the attacking colony males did not change the attack behavior of the vibrissectomized animals. These results indicate that the vibrissae are involved in defensive boxing behavior, but play no essential role in the elicitation or maintenance of conspecific attack in the rat. 相似文献

Specific agonistic responses of albino rats were compared for dominant colony rats and intruders, and for rats in a “reflexive fighting” task. The “reflexive fighters” showed high levels of defensive responses such as boxing and freezing, and very low levels of aggressive behaviors such as piloerection, biting, and the lateral display. This pattern clearly suggests that the behaviors measured in the reflexive fighting task reflect conspecific defensive reactions, rather than “shockelicited aggression.” Moreover, striking responses seen in the reflexive fighting task also occur at a high rate when footshock is given to a solitary rat held in a boxing posture. Thus it appears that “reflexive fighting” primarily involves defensive rather than aggressive responses. 相似文献

Film analysis and direct observation suggest that 2 very different types of intra-specific fights occur among Japanese brown bears maintained in large stable colonies. Disputes arising over food are short, and involve such activities as threatening, muzzling, chasing, and flight. Weapon use during feeding fights primarily involves slashing blows to the back or head areas of the opponent. In contrast, “spontaneous” fights are longer, and consist almost exclusively of wrestling, with bites and forepaw blows directed at the opponent's ruff area. These spontaneous fights occur primarily among the larger and higher-ranked male bears, especially among animals with closely adjacent rankings. It is suggested that such fights facilitate the establishment of dominance relationships by providing an opportunity for mutual assessment of strength and stamina without serious risk of injury. 相似文献
