电脑游戏与青少年问题行为、家庭各因素的关系研究

本研究着眼于探讨6、8、10年级的中学生的电脑游戏活动,以及游戏时间、游戏暴力程度、行为问题、父母教养方式、家庭收入等因素的相互作用。结果显示,6年级学生较之8和10年级学生有较少的行为问题。研究也发现,学生玩游戏时间越多,玩游戏的历史越长,具有行为问题的可能性越多。此外,那些游戏暴力指数较高的学生所得到的来自父母的温暖指数较少,有较多的问题行为。在游戏的暴力指数方面,女孩比男孩要低得多。父亲教养方式中的温暖和惩罚因子、母亲教养方式中的温暖、椎绡和惩罚因子可用于预测孩子的问题行为。     

咨询会谈中的人际互补及其与工作同盟、咨询效果的关系

Leary的人际理论将人际互动行为划分为“情感”和“控制”两个维度, 互动双方在情感维度的一致性和控制维度的互补性统称为人际互补。为探究心理咨询过程中人际互补的发展趋势及其与工作同盟、咨询效果的关系, 采用电脑操纵杆方法, 编制《咨询会谈人际互补行为评分手册》, 对16个个案的48个心理咨询会谈录像进行评估。结果表明：有经验的咨询师在咨询前期的情感轴一致性高于中期和后期, 在咨询后期的控制轴互补性高于前期和中期, 新手咨询师的情感轴一致性和控制轴互补性均无阶段性差异; 咨询中期的情感轴一致性负向预测工作同盟和会谈深度; 情感轴一致性呈高-低-高发展趋势的个案咨询效果更好。结论: 心理咨询的人际互补三阶段模型得到一定程度的支持, 其作用机制有待进一步验证。     

Infanticide by genetically deaf mice: Possible evidence for an inhibiting function of pups' ultrasonic calls

The influence of pup ultrasonic calls on male infanticidal behavior was evaluated by using mice of the GFF strain which includes two different lines: a normally hearing line and a genetically deaf line. Deaf male mice exhibited more infanticidal behavior than mice with normal hearing. In addition, deaf pups, which emitted fewer ultrasonic calls than normal pups, suffered a higher, even though not significant, rate of infanticidal behavior by normally hearing males. On the whole, these results question Labov's hypothesis that pups emit few ultrasounds in the presence of strange males in order to avoid being located and killed by them.

关于香港信息技术教育应用中师资准备状况的研究

通过对香港146名小学教师进行问卷调查,考察教师的电脑经验状况、学习和教学观念、电脑辅助教学态度及观念,并探讨它们之间的关系。结果表明,对电脑辅助教学持积极态度的人显著多于持消极态度的人,但多数教师并没有认识到电脑在教学中的独特潜力及其对教学范式转变的影响。电脑辅助教学态度与其电脑经验状况显著相关;电脑辅助教学观念既与其电脑经验显著相关又与其学习和教学观念显著相关。这些结果启示,教师培训应当将电脑技能与学习理论有机地结合起来进行。     

Enhanced social docility in male hooded rats by dermal cautery of the vibrissal pads

Ablation of the vibrissal pads in rats causes subsequent deposition of scar tissue with little or no regrowth of the vibrissae. Cauterized and intact mature male Long Evans rats were tested for shockelicited fighting, mouse killing, and colony intrusion forms of laboratory-induced aggression. The results revealed that only conspecific social fighting is blocked by ablation of the major vibrissal follicles. Although no significant group differences were noted in tests for mouse killing, shock-elicited paired fighting and territorial defense against a strange intruder were minimal in cauterized groups. The results emphasize the importance of specific sensory experience in reference to distinct forms of aggressive responding and support a new experimental technique for further investigation of sensory interactions with sources of aggressive behavior.     

The introduction of a group of alien mice (Mus musculus L.) into hierarchically organized groups of five male mice

Groups of 3 male or female Mus musculus were introduced into hierarchically organized colonies of 5 male mice for a period of 8 days. The colonies were of 2 kinds; high-level aggressive (HLA), which had been set up 3 days prior to the introduction of the aliens, and low-level aggressive (LLA), which had been established for 21 days before strangers were introduced. Both males and anestrous females were attacked, but males were attacked 5 times more frequently than females. In HLA colonies most of the attacks on the aliens were by the dominant; in LLA colonies there was no difference in the behavior of dominant and subordinate mice toward strangers. Both aggression toward aliens and intracolony aggression declined over the 8 day experimental period. In HLA colonies the dominant mouse mounted females 5 times more frequently than did either his subordinates or male mice in the LLA colonies. In HLA colonies aliens huddled with subordinates to form a single colony with 1 dominant and 7 subordinates. In LLA colonies alien males remained as a discrete group spatially separated in the cage. Female aliens were incorporated into the main colony. In all cases dominant male mice made more attacks on aliens as compared with familiar mice.     

Attack and defensive behaviors in the albino mouse

Attack by dominant male colony mice on intruders included chasing and lateral attack behaviors, while the corresponding intruder behaviors were flight, boxing, and checking. Both of these are similar to the attack and defensive behaviors of colony rats and intruders. However, mice did not show a significant constraint on bites to ventral areas, and the rat defensive behavior of lying on the back, which is effective because of this constraint, was rare; the corresponding “on-top” behavior of attackers was almost absent in mice. These findings strongly support the view that intraspecific attack and defensive behaviors, and target sites for bites, are interrelated factors facilitating effective but nonlethal agonistic interactions in muroid rodents.     

Flirting With Disaster: Short‐Term Mating Orientation and Hostile Sexism Predict Different Types of Sexual Harassment

We combine evolutionary and sociocultural accounts of sexual harassment, proposing that sexuality‐related and hostility‐related motives lead to different types of harassment. Specifically, men's short‐term mating orientation (STMO) was hypothesized to predict only unwanted sexual attention but not gender harassment, whereas men's hostile sexism (HS) was hypothesized to predict both unwanted sexual attention and gender harassment. As part of an alleged computer‐chat task, 100 male students could send sexualized personal remarks (representing unwanted sexual attention), sexist jokes (representing gender harassment), or nonharassing material to an attractive female target. Independently, participants’ STMO, HS, and sexual harassment myth acceptance (SHMA) were assessed. Correlational and path analyses revealed that STMO specifically predicted unwanted sexual attention, whereas HS predicted both unwanted sexual attention and gender harassment. Furthermore, SHMA fully mediated the effect of HS on gender harassment, but did not mediate effects of STMO or HS on unwanted sexual attention. Results are discussed in relation to motivational explanations for sexual harassment and antiharassment interventions. Aggr. Behav. 38:521‐531, 2012. © 2012 Wiley Periodicals, Inc.     

Ethical Concerns About Virtual Schools

Abstract

The emergence of a diverse range of virtual schools in recent times raises ethical concerns. The paper considers historical antecedents, and reflects on the contribution that virtual schools might make to individuals and to society. Despite their potential, virtual schools are seen as unsuitable for some students, and there are indications that they have sometimes been supported for inappropriate reasons. Concerns are also raised about the effectiveness of socialization, communications in a virtual school, and the moral distancing effect of educational technologies. Suggestions related to ethical issues are offered for parents who are considering virtual schools for their children.
