The Use of Referential Context and Grammatical Gender in Parsing: A Reply to Brysbaert and Mitchell (2000)

Based on the results of an event-related brain potentials (ERP) experiment (van Berkum, Brown, & Hagoort. 1999a, b), we have recently argued that discourse-level referential context can be taken into account extremely rapidly by the parser. Moreover, our ERP results indicated that local grammatical gender information, although available within a few hundred milliseconds from word onset, is not always used quickly enough to prevent the parser from considering a discourse-supported, but agreement-violating, syntactic analysis. In a comment on our work, Brysbaert and Mitchell (2000) have raised concerns about the methodology of our ERP experiment and have challenged our interpretation of the results. In this reply, we argue that these concerns are unwarranted and, that, in contrast to our own interpretation, the alternative explanations provided by Brysbaert and Mitchell do not account for the full pattern of ERP results.     

Applying a Family-Ecosystemic Model to Reunite a Family Separated Due to Child Abuse: A Case Study

Family reunification following the removal of a child due to child abuse is a challenging process. In this case study the authors demonstrate the success of a family-ecosystemic intervention for achieving the reintegration of an adolescent into her family following a court-imposed separation. The SET (Structural Ecosytems Therapy) model was used to: (1) repair family bonds, (2) build collaborations among the agencies involved in overseeing the child's welfare, and (3) build an alliance between the mother and agency personnel. This case study suggests that facilitating such collaborations can be helpful in the evaluation and follow-through of high risk cases.     

Nonconceptual Self-Consciousness And Cognitive Science

This paper explores some of the areaswhere neuroscientific and philosophical issuesintersect in the study of self-consciousness. Taking aspoint of departure a paradox (the paradox ofself-consciousness) that appears to blockphilosophical elucidation of self-consciousness, thepaper illustrates how the highly conceptual forms ofself-consciousness emerge from a rich foundation ofnonconceptual forms of self-awareness. Attention ispaid in particular to the primitive forms ofnonconceptual self-consciousness manifested in visualperception, somatic proprioception, spatial reasoningand interpersonal psychological interactions. Thestudy of these primitive forms of self-consciousnessis an interdisciplinaryenterprise and the paper considers a range of pointsof contact where philosophical work can illuminatework in the cognitive sciences, and vice versa.     

Discourse Before Gender: An Event-Related Brain Potential Study on the Interplay of Semantic and Syntactic Information During Spoken Language Understanding

A study is presented on the effects of discourse–semantic and lexical–syntactic information during spoken sentence processing. Event-related brain potentials (ERPs) were registered while subjects listened to discourses that ended in a sentence with a temporary syntactic ambiguity. The prior discourse–semantic information biased toward one analysis of the temporary ambiguity, whereas the lexical-syntactic information allowed only for the alternative analysis. The ERP results show that discourse–semantic information can momentarily take precedence over syntactic information, even if this violates grammatical gender agreement rules.     

Matrix correlation

A correlational measure for ann byp matrixX and ann byq matrixY assesses their relation without specifying either as a fixed target. This paper discusses a number of useful measures of correlation, with emphasis on measures which are invariant with respect to rotations or changes in singular values of either matrix. The maximization of matrix correlation with respect to transformationsXL andYM is discussed where one or both transformations are constrained to be orthogonal. Special attention is focussed on transformations which causeXL andYM to ben bys, wheres may be any number between 1 and min (p, q). An efficient algorithm is described for maximizing the correlation betweenXL andYM where analytic solutions do not exist. A factor analytic example is presented illustrating the advantages of various coefficients and of varying the number of columns of the transformed matrices.This research was supported by grant APA 0320 from the Natural Sciences and Engineering Research Council of Canada. The authors wish to acknowledge valuable discussion of this problem with Jan de Leeuw, University of Leiden.     

A joint treatment of varimax rotation and the problem of diagonalizing symmetric matrices simultaneously in the least-squares sense

The present paper contains a lemma which implies that varimax rotation can be interpreted as a special case of diagonalizing symmetric matrices as discussed in multidimensional scaling. It is shown that the solution by De Leeuw and Pruzansky is essentially equivalent to the solution by Kaiser. Necessary and sufficient conditions for maxima and minima are derived from first and second order partial derivatives. A counter-example by Gebhardt is reformulated and examined in terms of these conditions. It is concluded that Kaiser's method or, equivalently, the method by De Leeuw and Pruzansky is the most attractive method currently available for the problem at hand.The author is obliged to Dirk Knol for computational assistance and to Dirk Knol, Klaas Nevels and Frits Zegers for critically reviewing an earlier draft of this paper.     

Cognitive Avoidance in Phobia

It is suggested that anxious individuals would have a processing bias for threat only in the initial processing stage, whereas in the consecutive stages the more elaborate analysis of the stimulus would be inhibited. The purpose of this study was to investigate the stage in which the bias changed into avoidance and whether cognitive avoidance of threat is restricted to information that refers to the anxiety response as opposed to the threatening stimulus. Therefore, 37 spider phobics and 34 controls were administered a negative priming task and a free recall task, using threat words and neutral words, both divided into stimulus-related and response-related words. There was no indication of cognitive avoidance of the response-related threat words as assessed by the negative priming task. Recall findings indicated an incomplete memory bias in phobics, with a better recall of stimulus-related threat words instead of a worse recall of response-related threat words. This suggests a passive cognitive avoidance mechanism, which may still impede the processing of response-related information, crucial for the success of exposure therapy.     

Clinical Ethics: Theory Or Practice?

This article starts with a brief historical account of the ongoing debate about the status of clinical ethics: theory of practice. The author goes on to argue that clinical ethics is best understood as a practice. However, its practicality should not be measured by the extent to which clinical-ethical consultants manage to mediate or negotiate resolutions to ethical conflicts. Rather, clinical ethics is practical because it is characterized by a profound concern for the well-being of individual patients as well as the moral parameters of swift and urgent medical action in the face of limited supportive information.     

Normative Data for the Boston Naming Test in Native Dutch-Speaking Belgian Elderly

A normative study of the 60-item version of the Boston Naming Test (BNT) was performed in a group of 200 native Dutch-speaking Flemish elderly. Analysis of test results revealed that BNT performance in Dutch is significantly affected by age, years of education, and gender. Error analysis disclosed verbal semantic paraphasias to occur as the most frequent error type (1/3 errors). “Don't know responses,” verbal semantic paraphasias, and adequate circumlocutions were found on at least 30 different BNT items and constituted the most diffusely distributed error types. Following a careful review of other normative BNT studies, group characteristics rather than cultural differences were found to account for the difference in the overall mean scores. Our study surprisingly revealed that, as far as American–English, Australian–English and Dutch-speaking elderly are concerned, linguistics do not have an impact on the overall mean BNT score. A linguistic impact, however, clearly holds on the qualitative levels of performance, reflected by fundamental differences in the error distribution in different languages. Language-related BNT characteristics therefore stress the need for specific adaptations of norms.
