Intrasexual peer aggression and dating behavior during adolescence: an evolutionary perspective

It has been suggested that the use of intrasexual aggression is a form of competition associated with reproductive opportunities. Here the authors investigated the relationship between retrospective dating and flirting behavior and peer aggression and victimization during middle and high school. Results indicate that the use of peer aggression was associated with adaptive dating outcomes in both sexes, whereas experiencing peer victimization was correlated with maladaptive dating behaviors among females only. Females who perpetrated high levels of indirect (i.e. nonphysical) aggression reported that they began dating at earlier ages in comparison to their peers, whereas aggressive males reported having more total dating partners. Experiencing female-female peer victimization was correlated with a later onset of dating behavior, more total dating partners, and less male flirtation while growing up. This report strengthens the connection between adolescent peer aggression and reproductive competition, suggesting a potential functionality to adolescent peer aggression in enhancing one's own mating opportunities at the expense of rivals.     

The contradictory effects of nostalgic advertisements on nostalgia for products and on remembering advertisements1

Our purpose was to investigate the relationships between the names of items that easily evoke nostalgic feelings and nostalgic advertisements from the perspective of nostalgia for the names of these items and from the perspective of source monitoring. We measured the effect of nostalgia on source monitoring and whether the names of items evoked nostalgic feelings when they were presented alone. We found that, from the perspective of the nostalgic feelings, we directly demonstrated that the names of articles that easily evoke nostalgic feelings are more likely to evoke nostalgia when they are presented with nostalgic advertisements than when they are presented with non‐nostalgic advertisements. From the perspective of source monitoring, we revealed that nostalgic advertisements are more forgettable than non‐nostalgic advertisements when they present the names of articles that easily evoke nostalgic feelings.     

Social aggression and resource conflict across the female life-course in the Bolivian Amazon

This work explores sources of conflict among forager-horticulturalist women in Amazonian Bolivia, and applies life history theory as a tool for understanding competitive and cooperative social networking behaviors among women. In this study, 121 Tsimane women and girls were interviewed regarding current and past disagreements with others in their community to identify categories of contested resources that instigate interpersonal conflicts, often resulting in incidences of social aggression. Analysis of frequency data on quarrels (N = 334) reveals that women target several diverse categories of resources, with social types appearing as frequently as food and mates. It was also found that the focus of women's competition changes throughout the life-course, consistent with the notion that current vs. future reproduction and quantity-quality trade-offs might have different influences on competition and social conflict over resources within women's social networks across different age groups.     

Increased sensitivity to proactive and retroactive interference in amnestic mild cognitive impairment: new insights

Background

Increased sensitivity to proactive (PI) and retroactive (RI) interference has been observed in amnestic mild cognitive impairment (aMCI). PI and RI are often explained as being the result of a response competition mechanism. However, patients with aMCI are supposed to suffer mostly from encoding deficits. We hypothesized that in aMCI interference may occur at encoding and not only at the retrieval stage.

Material and methods

We developed an original paradigm enabling PI and RI to be tested with and without response competitors. Eighteen young controls (YC), 16 elderly controls (EC) and 15 aMCI participated in the study.

Results

The YC and EC groups presented interference effects only in conditions that included a direct response competitor. In contrast, aMCI had interference effects in all conditions including the one without response competitor.

Conclusion

Increased sensitivity to interference in aMCI appears to occur at the encoding/consolidation stage and not only at the retrieval stage, as is the case in healthy subjects. This result is discussed in the context of the associative encoding deficits characterizing aMCI.     

Effects of a rival's perceived motives on constructive competition within organizations: A competitive dynamics perspective

Previous work on constructive competition has focused on competitors' motives and strategies; however, competition is an interactive process that is affected by both the competitor and the rival. Based on the competitive dynamics perspective and attribution theory, this study examines the impact of a perceived rival's motives on the constructiveness of competition. The results of a survey of 521 employees from 25 companies in the banking and insurance industry in Taiwan revealed that the perceptions of rivals' motives significantly affected the constructiveness of competition. By introducing the perspective of rival analysis to individual‐level competition, the present study provides a more comprehensive understanding of constructive competition within organizations.     

Cue strength in second-language processing: An eye-tracking study

This study used eye-tracking and grammaticality judgement measures to examine how second-language (L2) learners process syntactic violations in English. Participants were native Arabic and native Mandarin Chinese speakers studying English as an L2, and monolingual English-speaking controls. The violations involved incorrect word order and differed in two ways predicted to be important by the unified competition model [UCM; MacWhinney, B. (2005). A unified model of language acquisition. In J. F. Kroll & A. M. B. de Groot (Eds.), Handbook of bilingualism: Psycholinguistic approaches (pp. 49–67). Oxford: Oxford University Press.]. First, one violation had more and stronger cues to ungrammaticality than the other. Second, the grammaticality of these word orders varied in Arabic and Mandarin Chinese. Sensitivity to violations was relatively quick overall, across all groups. Sensitivity also was related to the number and strength of cues to ungrammaticality regardless of native language, which is consistent with the general principles of the UCM. However, there was little evidence of cross-language transfer effects in either eye movements or grammaticality judgements.     

Cue competition effects in human causal learning

Five experiments involving human causal learning were conducted to compare the cue competition effects known as blocking and unovershadowing, in proactive and retroactive instantiations. Experiment 1 demonstrated reliable proactive blocking and unovershadowing but only retroactive unovershadowing. Experiment 2 replicated the same pattern and showed that the retroactive unovershadowing that was observed was interfered with by a secondary memory task that had no demonstrable effect on either proactive unovershadowing or blocking. Experiments 3a, 3b, and 3c demonstrated that retroactive unovershadowing was accompanied by an inflated memory effect not accompanying proactive unovershadowing. The differential pattern of proactive versus retroactive cue competition effects is discussed in relationship to amenable associative and inferential processing possibilities.     

Skultety's Categories of Competition – A Competing Conceptualisation?

A recent article in this journal attempts to link categories of sport competition to appropriate psychologies of participants in the different sorts of competition. It criticises accounts of competition which understand it in relation to a very restricted range of psychologies because the purposes and psychologies with which people enter and engage in competition vary enormously. So, taking as a starting point a consensus view among sport philosophers of the key conditions governing competition, work is undertaken to identify fundamental distinctions drawing from the conditions, which are said to result in a fourfold typology of competitions. The final step is to suggest psychologies most suited to the components of the typology. My article examines this project and produces reasons to doubt its success.     

Challenging sex segregation: A philosophical evaluation of the football association’s rules on mixed football

The Football Association (FA) has been under pressure to allow girls to play in mixed teams since 1978, following 12-year old Theresa Bennett’s application to play with boys in a local league. In 1991, over a decade after Bennett’s legal challenge, the FA agreed to remove its ban on mixed football and introduced Rule C4 in order to permit males and females to play together in competitive matches under the age of 11. More recently, following a campaign by parents, coaches, local Members of Parliament and the Women’s Sport Foundation, the FA agreed to trial mixed football for the under-12 to under-15 age categories in order to establish, among other things, the risk of injury to players in sex-integrated competitions. A series of exponential changes ensued: between 2010 and 2014, the age at which mixed football was permitted increased from U11 to U16. In 2015, the FA announced the decision to raise the age limit on mixed football from U16 to U18 for the forthcoming 2015–2016 season. We critically examine the reasons given by the FA for enforcing segregated participation beyond the age of 18, namely that males have an unfair advantage and that females face an unacceptable risk of injury. We also discuss the argument that removing the ban might harm the women’s game. In conclusion, we suggest that the FA ought to abandon the ban on mixed football over the age of 18.
