This paper reports on the ways in which new entities are introduced into discourse. First, we present the evidence in support of a model of indefinite reference processing based on three principles: the listener’s ability to make predictive inferences in order to decrease the unexpectedness of upcoming words, the availability to the speaker of grammatical constructions that customize predictive inferences, and the use of “expectancy monitors” to signal and facilitate the introduction of highly unpredictable entities. We provide evidence that one of these expectancy monitors in Dutch is the post-verbal variant of existential er (the equivalent of the unstressed existential “there” in English). In an eye-tracking experiment we demonstrate that the presence of er decreases the processing difficulties caused by low subject expectancy. A corpus-based regression analysis subsequently confirms that the production of er is determined almost exclusively by seven parameters of low subject expectancy. Together, the comprehension and production data suggest that while existential er functions as an expectancy monitor in much the same way as speech disfluencies (hesitations, pauses and filled pauses), er is a higher-level expectancy monitor because it is available in spoken and written discourse and because it is produced more systematically than any disfluency.  相似文献

Escalation of commitment refers to the tendency to persist with or even intensify losing courses of action. In this study, we examined whether authentic and contrived dissent reduces escalation in group decision making. Participants first individually indicated their preference on how to allocate money between two alternatives. Based on these individual preferences, homogeneous and heterogeneous three‐person groups were formed. In addition, group discussion was either structured by assigning one group member to play the role of a devil's advocate or was not structured. Results revealed that escalation tendencies over multiple decisions were reduced in heterogeneous groups that used the devil's advocacy procedure. The rationality of this behavior is discussed.

Contextual cueing occurs when repetitions of the distractor configuration are implicitly learned. This implicit learning leads to faster search times in repeated displays. Here, we investigated how search adapts to a change of the target location in old displays from a consistent location in the learning phase to a consistent new location in the transfer phase. In agreement with the literature, contextual cueing was accompanied by fewer fixations, a more efficient scan path and, specifically, an earlier onset of a monotonic gaze approach phase towards the target location in repeated displays. When the repeated context was no longer predictive of the old target location, search times and number of fixations for old displays increased to the level of novel displays. Along with this, scan paths for old and new displays became equally efficient. After the target location change, there was a bias of exploration towards the old target location, which soon disappeared. Thus, change of implicitly learned spatial relations between target and distractor configuration eliminated the advantageous effects of contextual cueing, but did not lead to a lasting impairment of search in repeated displays relative to novel displays.  相似文献

A prominent finding in escalating commitment and entrapment research is the “responsibility effect”: people invest more in a losing course of action or persist with it for longer if they themselves initiated this action (responsibility) as opposed to if it was assigned to them. We argue that this effect is driven by participants’ preferences. Responsible participants usually prefer the chosen alternative since they have chosen it themselves. Non-responsible participants, in contrast, represent a mix of persons who either favor or disfavor the chosen alternative. In two experiments, we demonstrate that responsible participants favor the chosen course of action more strongly than non-responsible participants do, that these preferences facilitate reinvestment in and persistence with the chosen course of action, and that responsibility has no effect over and above this effect of preferences. Non-responsible participants preferring the chosen course of action made similar reinvestments and exhibited similar persistence as responsible participants.  相似文献

Previous studies investigating the ability of high priority stimuli to grab attention reached contradictory outcomes. The present study used eye tracking to examine the effect of the presence of the self-face among other faces in a visual search task in which the face identity was task-irrelevant. We assessed whether the self-face (1) received prioritized selection (2) caused a difficulty to disengage attention, and (3) whether its status as target or distractor had a differential effect. We included another highly familiar face to control whether possible effects were self-face specific or could be explained by high familiarity. We found that the self-face interfered with the search task. This was not due to a prioritized processing but rather to a difficulty to disengage attention. Crucially, this effect seemed due to the self-face’s familiarity, as similar results were obtained with the other familiar face, and was modulated by the status of the face since it was stronger for targets than for distractors.  相似文献

Research has shown that neighborhoods play a role in the etiology of violence. However, few adolescent relationship aggression (ARA) studies have objective measures of violent neighborhoods. Drawing on a nationally representative sample of youth, this study examines the association between ARA and local levels of violent crime (measured using geocoded Uniform Crime Report data from each of the youths’ residential neighborhoods). Study analyses are based on survey data from 723 youth (ages 10–18) in current or recent dating relationships (351 males and 372 females) in the Survey on Teen Relationships and Intimate Violence (STRiV), a national representative household panel survey exploring interpersonal violence and related aggression among adolescents. About 19% of the sample reported ARA victimization in their most recent dating relationship (ARA perpetration was 17%). Neighborhood violent crime in the study (males living in 86.9 and females 99.8) was slightly lower than the national average of 100. With a broad national sample, 40% non-Whites, hypotheses guided by theories of neighborhood influence were tested. The study did not find an association between neighborhood violent crime and ARA victimization and perpetration, controlling for key demographic factors. The results, for a broad range of high- and low-crime neighborhoods, suggest that neighborhood violence does not seem to affect individual rates of ARA. The results suggest the ARA victimization and perpetration are perhaps ubiquitous and found both in low and high violent crime neighborhoods, suggesting that addressing local violent crime rates alone does not seem to be a path to also reducing ARA.  相似文献

Self-reports of health and well-being are central for population monitoring, so it is paramount that they are measured accurately. The goal of this study was to examine the impact of age on the use of the comparison standards or frames of reference (FoRs) in self-reports of health, life-satisfaction, fatigue, and pain, and to determine if the age-health outcome associations were affected by age differences in FoRs. Respondents (n = 2000) selected from the U.S. general population self-rated their life-satisfaction and health outcomes. Following this, they were asked to indicate if they used any comparisons (FoRs) when making their rating and the direction of these comparisons (upward, lateral or downward). Analyses examined (a) whether age groups differed in the type and direction of FoRs, and (b) whether age patterns in health, life-satisfaction, fatigue, and pain were altered when FoRs were statistically controlled. Compared to middle-aged and older people, younger respondents were more likely to compare themselves with other people when self-rating their health and life-satisfaction. They were also more likely to use a hypothetical situation when evaluating their pain and fatigue. Younger participants used lateral comparisons less often and downward comparisons more often than middle-aged and older participants. When these age differences in FoRs were statistically controlled, the observed age patterns in self-reported health outcomes were somewhat reduced. The results show that people of different ages use different FoRs when self-reporting their life-satisfaction and health outcomes.

Few pedagogical theories and practices have met with such strong reactive ambivalence in Germany as Dewey’s. As it contained the ideas of democracy and pragmatism it clashed with the monarchial and idealistic patterns of school-practice and pedagogic theory right from the beginning. On the other hand, reformists of all kinds were overwhelmed with enthusiasm. But even in the democratic phases of political development this ambivalence continued. The tradition of setting metaphysical and religious backgrounds stood in the way of a free examination of Dewey. Therefore, the reception has, up until now, been signed by mistakes and misinterpretations, but also by a minority of fruitful debates.  相似文献
