Three experiments examined the involvement of newly learnt words in lexical competition. Adult participants were familiarized with novel nonsense sequences that overlapped strongly with existing words (e.g. cathedruke, derived from cathedral) through repeated presentation in a phoneme-monitoring task. Experiment 1 looked at the immediate effects of exposure to these sequences, with participants showing familiarity with the form of the novel sequences in a two-alternative forced choice task. The effect of this exposure on lexical competition was examined by presenting the existing words (e.g. cathedral) in a lexical decision task. The immediate effect of the exposure was facilitatory, suggesting that the novel words had activated the representation of the closest real word rather than developing their own lexical representations. In Experiment 2, inhibitory lexical competition effects emerged over the course of 5 days for offset-diverging (e.g. cathedruke-cathedral) but not onset-diverging (e.g. yothedral-cathedral) novel words. Experiment 3 disentangled the roles of time and level-of-exposure in the lexicalization process and assessed the generality of the observed lexical inhibition using pause detection. A single, concentrated exposure session was used, which resulted in good recognition performance soon after. Lexicalization effects were absent immediately after exposure but emerged 1 week later, despite no intervening exposure to the novel items. These results suggest that integrating a novel word into the mental lexicon can be an extended process: phonological information is learnt swiftly, but full integration with existing items develops at a slower rate.  相似文献

ObjectivesOur aim was to investigate the link between youth soccer players' perceptions of the coach-initiated motivational goal climate within their team and their perceptions of inclusion as a function of societal status. Societal status refers to one's national background which numerically forms the majority or a minority in a particular society.Design and methodsSurvey data was collected among 245 male youth soccer players (M = 12.9 years, SD = 1.60), who all played in culturally diverse teams in the Netherlands. The societal status of 94 players (38.4%) was majority, and 151 players (61.6%) were classified as minority. To test our main hypothesis, perceived inclusion as the dependent variable was hierarchically regressed on coach-initiated mastery goal climate perceptions, performance goal climate perceptions, societal status, and their interactions.ResultsOverall, mastery goal perceptions and performance goal perceptions of intra-team competition were positively and negatively related, respectively, to perceived team inclusion. As hypothesized, only among players with a societal minority status, perceptions of inclusion were higher when mastery goal climate perceptions were higher and performance goal climate perceptions were lower.Discussion and conclusionOur findings suggest that a coach-initiated mastery-oriented team climate may enhance an inclusive soccer environment in culturally and nationally diverse teams. For societal minority players, intra-team competition should be de-emphasized by the coach in order to strengthen the experience of inclusion.  相似文献

Research has demonstrated that false memories are capable of priming and facilitating insight-based problem-solving tasks by increasing solution rates and decreasing solution times. The present research extended this finding by investigating whether false memories could be used to bias ambiguous insight-based problem-solving tasks in a similar manner. Compound remote associate task (CRAT) problems with two possible correct answers, a dominant and a non-dominant solution, were created and normed (Experiment 1). In Experiment 2, participants were asked to solve these CRAT problems after they were given Deese/Roediger-McDermott lists whose critical lures were also the non-dominant solution to half of the corresponding CRATs. As predicted, when false memories served as primes, solution rates were higher and solution times were faster for non-dominant than dominant CRAT solutions. This biasing effect was only found when participants falsely recalled the critical lure, and was not found when participants did not falsely recall the critical lure, or when they were not primed. Results are discussed with regard to spreading activation models of solution competition in problem-solving tasks and current theories of false memory priming effects.  相似文献

We demonstrate that a person's eye gaze and his/her competitiveness are closely intertwined in social decision making. In an exploratory examination of this relationship, Study 1 uses field data from a high‐stakes TV game show to demonstrate that the frequency by which contestants gaze at their opponent's eyes predicts their defection in a variant on the prisoner's dilemma. Studies 2 and 3 use experiments to examine the underlying causality and demonstrate that the relationship between gazing and competitive behavior is bi‐directional. In Study 2, fixation on the eyes, compared to the face, increases competitive behavior toward the target in an ultimatum game. In Study 3, we manipulate the framing of a negotiation (cooperative vs. competitive) and use an eye tracker to measure fixation number and time spent fixating on the counterpart's eyes. We find that a competitive negotiation elicits more gazing, which in turn leads to more competitive behavior.  相似文献

Introduction

Competition between French local communities to build infrastructures to attract enterprises and residents could sometimes result in irrational public spending.

Objectives

Show the influence of psychological factors and the phenomenon of escalating commitment in particular on this type of economic decision.

Method

We conducted a survey comprising four scenarios which were sent to 285 local elected representatives and we study the impact of the factors “Amount of sunk costs” and “Level of project completion” on two dependent variables, “the desire to complete the project” and “the judgment regarding the quality of the investment”. The scenarios presented a project which involve servicing a site and the construction of a road infrastructure in order to attract an enterprise.

Results

In conformity with the works of Boehne and Paese, whatever the dependent variable, the level of project completion significantly explains the escalation of commitment. The hypothesis of “sunk costs” is confirmed when the escalation of commitment is measured by the dependent variable “desire to complete the project”.

Conclusion

We have highlighted the effect of sunk costs and level of project completion on the decisions of local elected representatives, enriching the understanding of economic decision factors.  相似文献

合作与竞争是社会互动的两种主要形式,也是冲突解决的两种方法,对人际交往具有重要作用,一直以来都受到研究者的广泛关注。但是从心理与社会学角度研究合作与竞争的文献却相对较少,而对于精神障碍人群在合作与竞争中异常表现的原因目前也存在争议。本文从心理与社会学的角度出发,对合作与竞争的神经机制和生物基础进行综合论述,并对精神障碍人群在合作与竞争两种社会互动中的表现进行比较,试图为精神障碍人群在人际交往中的康复训练提供理论依据。  相似文献

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.

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.  相似文献

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.  相似文献

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.  相似文献
