Individuals with agrammatic Broca's aphasia experience difficulty when processing reversible non‐canonical sentences. Different accounts have been proposed to explain this phenomenon. The Trace Deletion account (Grodzinsky, 1995, 2000, 2006) attributes this deficit to an impairment in syntactic representations, whereas others (e.g., Caplan, Waters, Dede, Michaud, & Reddy, 2007; Haarmann, Just, & Carpenter, 1997) propose that the underlying structural representations are unimpaired, but sentence comprehension is affected by processing deficits, such as slow lexical activation, reduction in memory resources, slowed processing and/or intermittent deficiency, among others. We test the claims of two processing accounts, slowed processing and intermittent deficiency, and two versions of the Trace Deletion Hypothesis (TDH), in a computational framework for sentence processing (Lewis & Vasishth, 2005) implemented in ACT‐R (Anderson, Byrne, Douglass, Lebiere, & Qin, 2004). The assumption of slowed processing is operationalized as slow procedural memory, so that each processing action is performed slower than normal, and intermittent deficiency as extra noise in the procedural memory, so that the parsing steps are more noisy than normal. We operationalize the TDH as an absence of trace information in the parse tree. To test the predictions of the models implementing these theories, we use the data from a German sentence—picture matching study reported in Hanne, Sekerina, Vasishth, Burchert, and De Bleser (2011). The data consist of offline (sentence‐picture matching accuracies and response times) and online (eye fixation proportions) measures. From among the models considered, the model assuming that both slowed processing and intermittent deficiency are present emerges as the best model of sentence processing difficulty in aphasia. The modeling of individual differences suggests that, if we assume that patients have both slowed processing and intermittent deficiency, they have them in differing degrees. 相似文献
Black children are exposed to police violence at alarming rates. Such stress impacts development and treatment of physical health problems. In the current discourse, we introduce STYLE (Self-examination, Talk about community-police relations and racism, Yield space and time to anti-racism work, Learn about how structural racism impacts child health, Evaluate policies and practices through an anti-racism lens). STYLE offers a framework through which professionals in pediatric psychology can engage in anti-racist work across contexts from clinical care to academic and advocacy settings. Pediatric psychologists have a responsibility to be on the frontline as interventionists, educators, researchers, organizers, and advocates for racial justice through anti-racism practices. The current paper introduces STYLE in clinical care, community service, training/supervision, and academic and advocacy contexts. Case examples are provided. Professionals in pediatric psychology must first focus on changing their STYLE to promote individual and infrastructural change consistent with anti-racism work.
This paper is a review of leadership research, focusing primarily on women as leaders. The more recent perspective of studying leaders by examining followers is included; but research is sparse as to how leaders are perceived as empowering by their subordinates. A study in progress, conducted by Denmark, Nielson, and Scholl, indicates that stereotypes were more typically held by women against female leaders. However, a leader's ability to be empowering varies with status. The higher the status, the more empowering that individual is perceived, whether female or male. Yet, more men than women held higher status positions. More women are needed in high-level positions to better assess leadership and empowerment. 相似文献
A method used in program evaluation and public health research called concept mapping is examined in this article for its usefulness in feminist research. This method embodies several defining characteristics of feminist social science. Concept mapping is a single method that integrates qualitative and quantitative approaches, provides an opportunity for participants to work together as a group to develop an understanding of a concept, and places the participants in control of interpretation. Over the course of a six-step process, a group of people are assembled to discuss an issue or concept, moving toward a group understanding of that concept, which is then represented in a visual picture, or map. Concept mapping was used in the current study to examine how community resources for sexual-assault victims could be improved. A national random sample of 168 rape-victim advocates provided ideas as to how the legal, medical, and mental health systems could better serve victims. A subgroup of advocates then constructed and interpreted a concept map. The map suggested that rape victims still face many problems in seeking community help. Twelve clusters of broad-based and specific system changes were identified (e.g., fighting victim blaming, community education, sensitizing medical staff, legal reform). Implications for research on sexual assault and feminist research methodology are discussed. 相似文献
This Special Issue examines ethical challenges in community psychology research and practice. The literature on ethics in community psychology has remained largely abstract and aspirational, with few concrete examples and case studies, so the goal of this Special Issue was to expand our written discourse about ethical dilemmas in our field. In these articles, researchers and practitioners share stories of specific ethical challenges they faced and how they sought to resolve them. These first‐person narratives examine how ethical challenges come about, how community psychology values inform ethical decision making, and how lessons learned from these experiences can inform an ethical framework for community psychology. 相似文献
In this study, a priming Stroop paradigm was used to determine whether stereotype activation is unintentional. Priming conditions (priming/no‐priming) and the relationship between priming and target (consistent/inconsistent/no‐relation) were the independent variables; accuracy, reaction time and N400 amplitude were used as dependent variables. The reaction time revealed that stereotype activation is, to some extent, unintentional. Furthermore, the event‐related potenial (ERP) results showed that N400 amplitude was larger for inconsistent conditions than for consistent conditions. This result supported the notion that stereotype activation is an unintentional and automatic process. 相似文献
This study tested and refined a framework that proposes a mechanism for retrieving alternative causes and disabling conditions (Cummins, 1995) during reasoning. Experiment 1 examined the relation between different factors affecting retrieval. The test revealed high correlations between the number of possible alternative causes or disabling conditions and their strength of association and plausibility. Experiment 2 explored the hypothesis that due to a more extended search process, conditional inferences would last longer when many alternative causes or disabling conditions were available. Affirmation of the consequent (AC) and modus ponens (MP) latencies showed the hypothesized pattern. Denial of the antecedent (DA) and modus tollens (MT) inferences did not show latency effects. The experiment also identified an effect of the number of disabling conditions on AC and DA acceptance. Experiment 3 measured efficiency of disabler retrieval by a limited time, disabler generation task. As predicted, better disabler retrieval was related to lower acceptance of the MP and MT inferences. 相似文献
This research examined the extent to which research methods textbooks in psychology and general social science discuss feminist challenges and approaches to social science (N = 40 textbooks). Two dimensions were examined. First, within the nonsexist dimensions, textbooks were analyzed to determine if they used nonsexist language and if they discussed ways to avoid sexist bias in research. The second dimension was profeminist. Within this dimension four subdomains receiving considerable attention from feminist researchers were explored: (a) epistemology (or ways of knowing); (b) objectivity and subjectivity; (c) the relationship between the researcher and the researched; and (d) qualitative versus quantitative methodologies. Results demonstrated that although the majority of the textbooks did not use sexist language, they did not move much beyond this standard. There was little discussion of feminist challenges to these research issues. When the textbook authors did mention these topics, their analyses were most often inconsistent with feminist approaches. 相似文献
