Lexical projection and the interaction of syntax and semantics in parsing

A series of self-paced reading studies utilized an embedded anomaly technique to investigate long-distance dependencies with dative verbs. Previous research i our lab demonstrated that argument structure influences the gap-filling process. Experiment I extended that work by demonstrating that dative verbs pattern with other complex transitive verbs (i.e., a fronted filler that is implausible as the direct object will not be interpreted as the direct object until the absence of a noun phrase after the verb forces the postulation of a direct object gap. This pattern contrasts with that of transitive verbs that subcategorize for a single internal argument position, where fronted fillers are obligatorily interpreted as the direct object). Experiments 2 and 3 investigate the prediction that semantic analyses precede syntactic analyses in dative questions. It is argued that the lexical information about argument structure and thematic roles can guide semantic interpretation.This research was supported in part by NSF grant BNS-8617738 and NIH grant HD-22271.     

Lexical structure in parsing long-distance dependencies

We review a series of experiments investigating lexical influences in parsing sentences with long-distance dependencies. We report three primary results. First, gaps are posited and filled immediately following verbs that are typically used transitively, even when the filler is an implausible object of the verb. However, gaps are not posited after verbs that are typically used intransitively. Second, plausibility determines whether or not a filler is treated as the object of a verb when the verb is typically used with both a direct object and an infinitive complement. Finally, verb control information is used immediately in determining which noun phrase will be interpreted as the understood subject of an infinitive complement.     

Memory access: The effects of fact-oriented versus problem-oriented acquisition

This study examined the effects of similarity between the processing of acquisition and the processing of test materials on performance in a problem solving task. Previous work by Perfetto, Bransford, and Franks (1983) demonstrated that uninformed subjects’ failure to utilize relevant acquisition information in a later problem solving task is the result of a failure to spontaneously access such information. The present study demonstrated that spontaneous access can be enhanced when both acquisition and test materials are processed in a similar manner, that is, in a problem-oriented manner. Furthermore, the present findings indicate that the processing similarity leading to enhanced access is specific to particular acquisition and test items, rather than a general problem solving set induced at acquisition and the subsequent testing situation. Results are interpreted within a transfer-appropriate processing perspective.     

Person–Situation Interaction in Adaptive Emotional Functioning

Two studies applied a person–situation model to examine the effect of emotional affordances of situations. Participants rated their emotional functioning as more extensive in situations classified as being high in emotional affordance than those classified as low in emotional affordance. Participants who scored higher on the individual difference characteristic of emotional intelligence were more interested in entering high emotional affordance situations than were individuals lower in emotional intelligence, and participants who scored higher on emotional intelligence were rated by others as being more successful in high emotional affordance situations than individuals lower in emotional intelligence. These results provide preliminary evidence that the interaction between emotional intelligence and situations may influence emotional functioning.     

Exploring the Factor Structure of the Social Cognition and Object Relations–Global Rating Method: Support for Two- and Three-Factor Models

The Social Cognition and Object Relations Scales–Global Rating Method (SCORS–G) contains 8 scales for coding narrative content. This study explores the factor structure of this measure using college (n = 171), outpatient (n = 239), and inpatient (n = 78) samples. Participants told stories to the Thematic Apperception Test (TAT; Murray, 1943) cards. Stories were transcribed and coded by blind raters using the SCORS–G. Cases were randomly assigned to an exploratory or validation group. Exploratory factor analysis with the exploratory group suggested 2- and 3-factor models. The Emotional Investment in Relationships (EIR) scale did not obtain a primary loading on any factor and was not included in subsequentmodels. After modifications, confirmatory factor analysis indicated good-to-adequate fit for 2- and 3-factor models. Both models showed good fit in the validation group and met criteria for invariance across models. Findings indicated that some SCORS–G scales tap cognitive-structural elements, whereas others assess affective-relational components of narratives. We found mild support separating the affective-relational scales in terms of internal representations for the self and others and relationships. The results reported here indicate that clinicians and researchers can calculate a separate cognitive-structural composite score and an affective-relational composite score when using the SCORS–G to rate TAT stories.     

A Systematic Review of Cognition in Chiari I Malformation

Displacement of the cerebellar tonsils in Chiari type I malformation (CMI) can affect functions controlled by the cerebellum and brainstem. While playing an integral role in the control of movement, the cerebellum also has widespread cortical connections, influencing a range of cognitive process. A systematic literature review was conducted to examine the relationship between cognition and CMI, assessing evidence for general or domain-specific cognitive change. The search protocol examined the AMED, CINAHL, Cochrane Library, EMBASE, MEDLINE, PsycINFO, and Scopus databases. Articles meeting the following criteria were included in this review (i) examined children or adults with a clinically defined diagnosis of CMI, (ii) assessed cognitive function with a prospective examination, (iii) included at least one standardized instrument designed to measure general or specific domains of cognitive function, and (iv) were published in English in a peer-reviewed journal. Twelve articles were identified, including 783 cases aged 3 months to 64 years. General cognition, processing speed, and learning and memory appeared less affected, while language deficits appeared to diminish with age. Executive dysfunction was the most commonly reported cognitive impairment, while attention and working memory, and visuospatial and perceptual skills also appeared vulnerable. Numerous methodological limitations were identified that should be considered in interpreting the impact of CMI and planning future investigations. Overall, there is currently insufficient evidence to describe a valid and reliable profile of cognitive impairment in CMI. Further research is required to confirm these preliminary psychometric results and integrate them with pathophysiological models     

Procrastination,Hoarding, and Attention Beyond Age 65 a Community-Based Study

We examined procrastination, hoarding, and attention in 80 older adults in community samples in the American South. Volunteers completed Lay’s General Procrastination Inventory, Frost, Steketee, and Grisham’s Saving Inventory Revised, the Oral Trail Making Test, a computerized Stroop Color Word Test, and measures of semantic and phonemic verbal fluencies. Findings suggest that procrastination affects older adults and it may be reliably measured. As with younger people procrastination and hoarding correlated in a positive direction. Hoarding correlated negatively with performance on the Trail Making Test Part B and the Color Word Score on a modified version of the Stroop Test. Hoarding also correlated negatively with Semantic Fluency though not with Phonemic Fluency. Procrastination correlated significantly and negatively only with Semantic Fluency and not with other attention measures. Limitations of the study and implications for future research are discussed.
