Online interpretation of scalar quantifiers: insight into the semantics-pragmatics interface

Scalar implicature has served as a test case for exploring the relations between semantic and pragmatic processes during language comprehension. Most studies have used reaction time methods and the results have been variable. In these studies, we use the visual-world paradigm to investigate implicature. We recorded participants’ eye movements during commands like “Point to the girl that has some of the socks” in the presence of a display in which one girl had two of four socks and another had three of three soccer balls. These utterances contained an initial period of ambiguity in which the semantics of some was compatible with both characters. This ambiguity could be immediately resolved by a pragmatic implicature which would restrict some to a proper subset. Instead in Experiments 1 and 2, we found that participants were substantially delayed, suggesting a lag between semantic and pragmatic processing. In Experiment 3, we examined interpretations of some when competitors were inconsistent with the semantics (girl with socks vs. girl with no socks). We found quick resolution of the target, suggesting that previous delays were specifically linked to pragmatic analysis.     

Are errors differentiable from deceptive responses when feigning memory impairment? An fMRI study

Previous neuroimaging studies have suggested that the neural activity associated with truthful recall, with false memory, and with feigned memory impairment are different from one another. Here, we report a functional magnetic resonance imaging (fMRI) study that addressed an important but yet unanswered question: Is the neural activity associated with intentional faked responses and with errors differentiable? Using a word list learning recognition paradigm, the findings of this mixed event-related fMRI study clearly indicated that the brain activity associated with intentional faked responses was different to the activity associated with errors committed unintentionally. For intentional faked responses, significant activation was found in the ventrolateral prefrontal cortex, the posterior cingulate region, and the precuneus. However, no significant activation was observed for unintentional errors. The results suggest that deception, in terms of feigning memory impairment, is not only more cognitively demanding than making unintentional errors but also utilizes different cognitive processes.     

文章结构清晰度对修改的影响研究

研究了文章结构清晰度对文章修改的影响。高低水平的作者各分别修改结构清晰度不同的材料。实验结果表明,文章修改质量的水平差异显著;文章结构清晰有助于修改者在修改过程中建构文章的整体模式,从而促进意义错误的修改。文章结构清晰度对修改的影响主要是通过影响工作记忆资源的分配而实现的。     

Avoiding Anxiety,Being in Denial,or Simply Stroking Self‐Esteem: Why Self‐Positivity?

This article studies the presence, resilience, and direction of the self‐positivity bias under various conditions to examine the role of self‐esteem maintenance as an important antecedent for the bias. Experiment 1 manipulates the perceptions of the uncontrollability of cancer and presence of base‐rate information as independent variables that together eliminate the self‐positivity bias in perceptions of the risk of cancer. Experiment 2 shows the same effects using 4 life events that differ in terms of valence and perceived controllability; that is, base‐rate information affects self‐estimates for uncontrollable life events, reducing the self‐positivity bias, but does not affect self‐estimates for controllable events. Experiment 3 shows that these effects only apply to optimistic individuals who fail to incorporate base‐rate information into their self‐perceptions for controllable events. In contrast, pessimists use base rates to update their self‐estimates irrespective of the controllability of the event. Overall, the pattern suggests that self‐positivity is attenuated in conditions that implicate self‐esteem. Implications for health care marketing are discussed.

特质焦虑大学生注意偏向的实验研究

焦虑与注意偏向的研究是近年来情绪与认知领域的热点.本研究采用点探测和线索靶子两个实验任务来探讨特质焦虑大学生注意偏向的特点及其内在机制.结果表明:(1)高特质焦虑大学生对负性情绪词附近靶刺激的反应时显著短于中性和正性情绪词附近的靶刺激.表现出一种对负性刺激的注意偏向.而低特质焦虑大学生没有出现注意偏向;(2)高低特质焦虑大学生在有效线索情况下反应时没有显著差异;在无效线索情况下.高特质焦虑大学生对以负性情绪词为线索的靶刺激反应时显著长于对其他靶刺激的反应时,表现出一种对负性刺激的空间注意的解除困难.因此,高特质焦虑个体对负性刺激的注意偏向是一种注意解除困难.     

Pooling data from multiple longitudinal studies: the role of item response theory in integrative data analysis

There are a number of significant challenges researchers encounter when studying development over an extended period of time, including subject attrition, the changing of measurement structures across groups and developmental periods, and the need to invest substantial time and money. Integrative data analysis is an emerging set of methodologies that allows researchers to overcome many of the challenges of single-sample designs through the pooling of data drawn from multiple existing developmental studies. This approach is characterized by a host of advantages, but this also introduces several new complexities that must be addressed prior to broad adoption by developmental researchers. In this article, the authors focus on methods for fitting measurement models and creating scale scores using data drawn from multiple longitudinal studies. The authors present findings from the analysis of repeated measures of internalizing symptomatology that were pooled from three existing developmental studies. The authors describe and demonstrate each step in the analysis and conclude with a discussion of potential limitations and directions for future research.     

Changes in suicide methods in Quebec between 1987 and 2000: the possible impact of bill C-17 requiring safe storage of firearms

This study presents the changes in the overall and firearm suicide rates for Québec (Canada) before and after Bill C-17, which was implemented to secure safe storage of firearms. It covers 20,009 suicide cases reported to the coroner's office. Interrupted time series analysis is used to compare suicide rates in the two periods. Firearm suicide rates have dropped among males and females, but the downward trends were not significant when compared to those prior to the law. Hanging suicide rates have risen considerably among men and women, but those upward trends did not increase significantly when compared with those preceding the law. The decline in suicide rates involving firearms has not resulted in a parallel decline in overall suicide rates. The analyses suggest that Bill C-17 neither improved the downward trend in firearm suicide, which had already begun before the enactment of the law, nor reduced the upward trend of the overall suicide rate. Correlation analyses between firearm suicide, hanging suicide, and the overall suicide rate suggest that firearm suicide is replaced by hanging suicide among males.     

A brief exploration of the development of internet use for communication among undergraduate students.

This study examined the growth in e-mail, MSN, and chatroom uses longitudinally among 280 Taiwanese college students. Data were collected at five points in time over a two-and-half-year period. Little change in the mean level of e-mail use was observed, while MSN showed an inverse U-shaped development. The use of chatroom seemed to decrease slightly over time. Almost all autocorrelations for three mediums were statistically significant. As moderate to low correlations were found among e-mail, MSN, and chatroom uses, future research should explore which factors may affect the growth of these three mediums.
