Making and correcting errors during sentence comprehension: Eye movements in the analysis of structurally ambiguous sentences

Eye movements were recorded as subjects read sentences containing temporary structural ambiguities. In accord with the garden-path theory of sentence comprehension, shorter reading times were found for sentences conforming to certain independently motivated parsing strategies (late closure and minimal attachment) than for comparable sentences which violate these strategies. Further, longer fixation durations were associated with the very first fixation in the region of the sentence which disambiguated the sentence, suggesting that the human sentence-parsing mechanism operates in a rather systematic fashion, immediately computing the structural consequences of fixated material for the analysis of preceding material. The pattern of regressive eye movements did not conform to the view that the parsing mechanism automatically returns to the beginning of the sentence to revise an incorrect analysis of linguistic material nor did it support the view that the parsing mechanism systematically backtracks through the sentence until the source of the erroneous analysis is located. Rather, the pattern of regressions indicated that the parsing mechanism typically engages in selective reanalysis, exploiting whatever information it has available about the type of error it has committed to guide its reanalysis attempts. Finally, it is emphasized that an understanding of the parser's revision procedures is essential to an explanation of why certain linguistic structures cannot be successfully parsed by humans.

On Bound Variable Interpretations: The LF-Only Hypothesis

Under what conditions do perceivers prefer to assign a bound variable interpretation to a pronominal that is ambiguous between a bound variable and a coreferential interpretation? Several experiments were designed to test the hypothesis that language perceivers prefer a bound variable over a coreferential interpretation of a pronoun because the former only requires consultation of a logical form (LF) representation, while the latter requires access to a discourse representation. The hypothesis was disconfirmed in two respects. First, although bound variable interpretations show a processing advantage over coreferential interpretations in VP ellipsis constructions, the preference for bound variable interpretations is not general--it does not extend to other quantificational contexts. Second, the preference for bound variable interpretations in VP ellipsis constructions is not limited to examples in which the antecedent and the ellipsis site occur in the same sentence. If the bound variable advantage were due to the ready availability of the LF for the current sentence, the advantage should disappear across sentence boundaries. An alternative hypothesis is then considered which could explain the source of the bound variable advantage in VP ellipsis contexts.     

Processing Coordinate Structures

Coordination often involves syntactically like categories. Based on the results of four reading time studies, it is argued here that the syntactic like-category restriction is not grammatical. Coordination of unlike categories can be just as acceptable as coordination of like categories. However, syntactically like category coordination is processed faster than coordination of unlike categories even when the two sentence types are judged to be fully acceptable. Further, parallelism of conjuncts facilitates processing regardless of whether it is parallelism in the category of the conjuncts (a property which the grammar might regulate) or parallelism in the internal structure of the conjuncts (a property which the grammar does not regulate, on anyone's view). Parallelism did not facilitate processing when the structure of a subject and object were manipulated, implying that parallelism effects are largely limited to the conjuncts of a coordinate structure and not due simply to the repetition of a phrase with a particular shape.     

Cognitive vulnerability to depression: a taxometric analysis

Although there is increasing support for the hypothesis that negative cognitive styles contribute vulnerability to depression, it remains unclear how best to conceptualize the heterogeneity in cognitive vulnerability to depression. Specifically, does this heterogeneity reflect quantitative or qualitative differences among individuals? The goal of this study was to address this question by examining whether the underlying structure of cognitive vulnerability to depression is best conceptualized as dimensional or categorical. Taxometric analyses provided consistent support for the dimensional nature of negative cognitive styles. It appears, therefore, that cognitive vulnerability to depression is best conceptualized as a dimensional construct, present to a greater or lesser extent in all individuals. Despite this, the strength of the relationship between negative cognitive styles and depressive symptoms does appear to vary as a function of where along the cognitive style continuum one falls.     

Perceived control and distress following sexual assault: a longitudinal test of a new model

Longitudinal data were collected from female sexual assault survivors (N = 171) at 4 points postassault. Consistent with the predictions of the temporal model (P. Frazier, M. Berman, & J. Steward, 2002), past, present, and future control were differentially related to posttrauma distress. Both personal past (behavioral self-blame) and vicarious past (rapist blame) control were associated with higher distress levels. In addition, the belief that future assaults are less likely was more strongly associated with lower distress levels than was future control. Present control (i.e., control over the recovery process) was most adaptive. Hierarchical linear modeling analyses revealed that changes in perceived control were associated with changes in distress after linear change in distress over time was accounted for.     

The Pronoun Bias Effect Strikes Again: A Reply to Pynte and Colonna

The gender of an initial adjectival phase (AP) influences the analysis of a phrase which is a potential main clause subject in French. Pynte and Colonna (this issue) establish this generalization but analyze it without considering critical aspects of sentence structure, specifically, the fact that the AP has a null pronominal subject. If grammars contain a violable constraint requiring coreference between the pronominal subject of an initial subordinate phrase and the subject of the main clause, then in Pynte and Colonna's study perceivers must choose on-line between an analysis which satisfies the same subject constraint and one which doesn't. From this perspective, it is expected that the subject analysis of the ambiguous phrase predominates. Further, on this view, the preference fits with independent generalizations about language such as the existence of switch-reference languages which obligatorily mark the coreference relation between the initial subordinate subject and the main clause subject. It also fits with already established facts about language processing, such as Cowart and Cairns' (1987) Pronoun Bias Effect.     

Assessment and Diagnosis of Eating Disorders: A Guide for Professional Counselors

Despite the prevalence of and risk associated with disordered eating, there are few guidelines for counselors on how to conduct an eating disorder assessment. Given the importance of the clinical interview, the purpose of this article is to provide recommendations for the assessment and diagnosis of eating disorders that (a) specifically focus on assessment in the context of a clinical interview and (b) can be used by counselors whether or not they specialize in eating disorder treatment.     

Electrodermal responses to sources of dual-task interference

There is a response selection bottleneck that is responsible for dual-task interference. How the response selection bottleneck operates was addressed in three dual-task experiments. The overlap between two tasks (as indexed by the stimulus onset asynchrony [SOA]) was systematically manipulated, and both reaction time and electrodermal activity were measured. In addition, each experiment also manipulated some aspect of the difficulty of either task. Both increasing task overlap by reducing SOA and increasing the difficulty of either task lengthened reaction times. Electrodermal response was strongly affected by task difficulty but was only weakly affected by SOA, and in a different manner from reaction time. A fourth experiment found that the subjectively perceived difficulty of a dual-task trial was affected both by task difficulty and by SOA, but in different ways than electrodermal activity. Overall, the results were not consistent with a response selection bottleneck that involves processes of voluntary, executive attention. Instead, the results converge with findings from neural network modeling to suggest that the delay of one task while another is being processed reflects the operation of a routing mechanism that can process only one stream of information for action at a time and of a passive, structural store that temporarily holds information for the delayed task. The results suggest that conventional blocked or event-related neuroimaging designs may be inadequate to identify the mechanism of operation of the response selection bottleneck.
