Predicting dating behavior from aggression and self‐perceived social status in adolescence

We investigated the longitudinal associations between self‐reported aggression, self‐perceived social status, and dating in adolescence using an intrasexual competition theoretical framework. Participants consisted of 536 students in Grade 9 (age 15), recruited from a community sample, who were assessed on a yearly basis until they were in Grade 11 (age 17). Adolescents self‐reported their use of direct and indirect aggression, social status, and number of dating partners. A cross‐lagged panel model that controlled for within‐time covariance and across‐time stability while examining cross‐lagged pathways was used to analyze the data. The findings revealed that direct aggression did not predict dating behavior and was negatively associated with self‐perceived social status in Grade 10. Self‐perceived social status in Grade 9 was positively associated with greater use of indirect aggression in Grade 10. Regarding dating, in Grade 9, self‐perceived social status positively predicted more dating partners the following year, while in Grade 10, it was higher levels of indirect aggression that predicted greater dating activity the following year. Overall, there were no significant sex differences in the model. The study supports the utility of evolutionary psychological theory in explaining peer aggression, and suggests that although social status can increase dating opportunities, as adolescents mature, indirect aggression becomes the most successful and strategic means of competing intrasexually and gaining mating advantages.

     

Competing Explanations and Explaining-Away Arguments

An “explaining-away argument” [EAA] aims to discredit some explanatory hypothesis by appealing to the explanatory power of an alternative hypothesis. Nietzsche's genealogical argument against theism and Darwin's case against Paley's “old argument of design in nature” are famous examples. In order for EAAs to have their negative force, they must satisfy several conditions. After clarifying these conditions, I focus in on one in particular: the two hypotheses in question offer potential explanations that compete with one another. I develop a formal account of what it takes for potential explanations to compete, and I use this account to argue that EAAs are often misapplied today. This is due to the fact that philosophers often fail to appreciate the subtle line dividing competing from non-competing explanations.     

Representing disability in charity promotions

Social psychological research in relation to charity advertising in the area of disability has attempted to distinguish between ‘positive’ and ‘negative’ images and the way in which these are related to their fundraising potential. In the light of the critique of charity advertising offered by a number of disability theorists, it is suggested that this perspective would be enhanced by consideration of the attitudes of disabled people to charity advertisements. A study is reported that compares the attitudes of disabled and non‐disabled people to two charity advertisements. Differences between these two groups are reported and in the light of the nature of these it is suggested that what are considered to constitute ‘positive images’ is unlikely to be consensual.

Consumer evaluation of net utility: Effects of competition on consumer brand selection processes

This study explores how brand-related information is integrated within a competitive environment. Specifically, we develop a structural equation model of competition between two brands, which includes each brand's price-quality characteristics (i.e., net utility). The model simultaneously tests how the net utility of the focal and competing brands affects consumers' attitudes, intentions, and choice regarding the focal brand. This study extends existing research with the findings that price-quality evaluations of a focal brand and net utility perceptions of competing brands influence consumers' attitudes, intentions, and choice regarding the focal brand. Thus, in order to attract consumers to their brands, marketers should focus not only on improving the performance and net utility of their own brands, but also on studying competing brands in the marketplace.     

Fallow deer tactic to compete over food with red deer

Small ungulates may compete with larger species through higher mobility, greater aggressiveness, and/or by larger group sizes. We observed a herd of approximately 100 red deer (Cervus elaphus) and 130 fallow deer (Dama dama) at the Žehušice Deer Park during supplemental feeding to determine whether fallow deer can displace red deer at feeding sites and to describe strategies used for displacement. Data were analyzed during the antlered period (AP) when males of both species had hard antlers and the cast period (CP) when all red deer stags had cast antlers, but fallow bucks were still in a hard antler. We conducted 41 observation sessions, 29 during the AP and 12 during the CP. In both periods red deer were more numerous than fallow deer at the feeding sites. Fallow bucks initially waited until red deer arrived at the feeding site, after which they attacked any red deer. Fallow bucks were more aggressive than red deer stags or hinds. When stags retaliated, the bucks turned their attacks toward hinds. During feeding sessions, attacks against hinds intensified, while bucks avoided encounters with stags. As a result, in most cases (90%), red deer vacated the feeding site before the supplementary food was depleted. In contrast, fallow does not compete with the larger red deer and selected other sources of food in the park. © 1996 Wiley-Liss, Inc.     

男性监控配偶、配偶不贞与精子竞争的关系

精子竞争是指同一女性产道中两个或两个以上男人的精子相互竞争卵子的过程。女性得到社会承认的性伙伴可能因精子竞争失败而损失惨重,因为女性私通可能引起男性投资于不携带自己基因的后代。过去研究表明进化而来的男性配偶监控策略可以防止女性不贞,减少精子竞争失败的危险。当前研究发现男性与配偶进行性行为后离别时间越久,男性就越采取出其不意地打电话、独占配偶时间、威胁对配偶感兴趣的男性等手段来监控配偶     

知晓感和学习判断产生机制的实验研究

以汉语配对词为实验材料,在已有实验研究的基础上,采用干扰模式进一步探讨了关于知晓感(Feeling of knowing)和学习判断(Judgment of learning)产生机制的四种理论假说,即线索熟悉性假说、目标提取假说、可接近性假说和竞争性假说。实验结果表明:在干扰条件下,知晓感和学习判断符合竞争性假说。     

不同教师群体激励因素的比较研究

本研究选择云南曲靖和浙江宁波的两所师范学校作为研究对象,以教育人种学研究方法为基本方法,通过现象分析、个案访谈、问卷调查、文献分析等途径,对不同地区教师群体的工作积极性状态及其原因进行了实证性对比研究,得出以下结论:竞争压力和相对报酬之间的相互关系是决定不同教师群体工作积极性大小的两个关键因素。其中竞争因素的激励功能相对较强。竞争压力大小与相对报酬高低之间的相互关系影响着群体激励力量的大小。     

The effect of a subliminally primed context on intrasexual competition depends on individual differences in sex drive

We argue that sex drive can be regarded as a fundamental correlate of individual differences in mating strategies, and that it modulates men’s tendencies to engage in intrasexual competition. We expected that men with a high sex drive would be more threatened by a rival in a sexual context than in a commitment context, whereas men with a low sex drive would be more threatened by a rival in a commitment context. Male participants were subliminally primed with either sex-related or commitment-related words, and then confronted with a romantic rival. The results confirm expectations and are discussed in light of other research.     

卷入影响广告理性诉求信息加工效果的眼动研究

使用眼动技术,考察了卷入的两方面（个人卷入与产品卷入）共同对广告理性诉求信息加工效果的影响。研究发现：（1）随着个人卷入或产品卷入度的提高,被试获得的广告信息显著增加。（2）仅在产品卷入度高时,强说服证据理性诉求广告的品牌信息所获得的加工深度才明显优于弱说服证据者;同时,只有当个人卷入度高时,产品卷入度高的商品信息所获得的加工才明显比产品卷入度低者更为精细。这说明,广告理性诉求方式可能主要适宜于宣传产品卷入度高的商品,且只有当个人卷入度高时才可能更为有效
