Variations on incremental interpretation

The strict competence hypothesis has sparked a small dialogue among several researchers attempting to understand its ramifications for human sentence processing and incremental interpretation in particular. In this paper, we review the dialogue, reconstructing the arguments in an attempt to make them more uniform and crisp, and provide our own analyses of certain of the issues that arise. We argue that strict competence, because it requires a synchronous computation mechanism, may actually lead to more complex, rather than simpler, models of incremental interpretation. Asynchronous computation, which is arguably both psychologically more plausible and conceptually more basic, allows for incremental interpretation to fall out naturally, without additional machinery for interpreting partial constituents. We show that this is true regardless of whether the presumed interpretation mechanism is top-down or bottom-up, contra previous conclusions in the literature, and propose a particular implementation of some of these ideas using a novel representation based on tree-adjoining grammars.The research in this paper was supported in part by grant IRI-9157996 from the National Science Foundation to the first author.

The effects of right hemisphere damage on the pragmatic interpretation of conversational remarks

The ability to interpret conversational utterances was assessed in a group of 12 male patients with unilateral right hemisphere brain damage (RHD) and 12 non-brain-damaged, age-matched male control subjects. Subjects listened to short vignettes which described both the affective tone of the relationship between a speaker and an actor, and the actor's performance on a task. Each vignette concluded with the speaker characterizing the actor's performance. In half of the items, the speaker's utterance was literally true; in the other half, the utterance was literally false and invited a nonliteral interpretation. Results showed no appreciable differences in the performance of control subjects and RHD patients when interpreting literally true utterances. In contrast, the two groups differed reliably when interpreting the pragmatic intent of nonliteral utterances: Control subjects used information about both the actor's performance and the speaker-actor relationship, while RHD patients demonstrated difficulty in using the information about the speaker-actor relationship. Results have implications for patients' understanding of essential elements of conversations, such as characters' internal states and their intentions in employing different forms of literal and nonliteral language.     

Lexical integration across saccades in reading

Summary Eye movements were recorded during sentence reading to examine the integration of parafoveal text across fixations. Four viewing conditions were used, each affording full view of the directly fixated word: no preview of the spatially adjacent parafoveal word; preview of its beginning trigram; preview of its beginning four letters; or preview of all its constituent letters. The magnitude of parafoveal-preview benefits (the difference between the no-preview condition and the different parafoveal-preview conditions) was examined as a function of the size of the saccade to the parafoveal target and as a function of the subsequent fixation location at the previewed target. The results revealed no effects of saccade size on parafoveal-preview benefits, but large effects of fixation position during the initial target fixation. Furthermore, parafoveal previews were used during the initial target fixation and during subsequent intratarget refixations. The results support a lexical-text-integration hypothesis which posits that lexical information is integrated across interword fixations and intraword refixations.     

Freud, Oedipus and the Hebrew Bible

The current paper examines the question of why Freud employed Greek rather than Hebrew foundation legends, specifically the story of Oedipus, as a basis for psychoanalysis, Freud's choice of Oedipus emanates from his deterministic view of the universe, paralleling the Greek rather that the Biblical story of creation. In the Biblical account God precedes and creates nature with no sign of an Oedipal conflict. In the Greek account, nature precedes the gods and the Oedipal conflict is inherent. Freud's choice has implications for his view of human psychology.     

Are All Hostility Scales Alike? Factor Structure and Covariation Among Measures of Hostility1

Few studies have examined the correlational and structural relationships between measures of hostility that may predict coronary heart disease. Using data from a population-based study (N= 2,682), we examined the factor structure among the five subscales from Siegel's (1986) Multi-dimensional Anger Inventory, the three subscales from Spielberger et al.'s (1985) anger expression scales, a Cook-Medley (Cook & Madley, 1954) hostility subscale that measures cynicism, and items measuring hostility from four scales that assess Type A behavior. Eight separate factors were identified: hostile anger expression, perceived control over the expression of one's anger, frequency of anger, ease of anger provocation, brooding, hostile outlook, cynicism, and sullenness. These results suggest that the structure of hostility measures is more complex than previous factor analyses have suggested. Our findings point to the dangers in assuming that a factor structure can be generalized beyond the data on which it is based to provide theoretical statements about psychological structure. The new scales appear to be valid because they correlate with demographic variables and indicators of social support in the expected directions.     

Working with older adults and their families – a review

This paper discusses family work with older adults by exploring some of the related literature published since Herr and Weakland's work in 1979, and compares psychoeducational and systems-based approaches to work with later life families. Issues of bias and omissions in the existing literature, and the definition of family therapy with this client group are raised. Areas for future research are indicated.     

The effects of observation on emotional arousal and affiliation

This study assessed the influence of anticipated experimenter surveillance during the performance of a painful or potentially embarrassing act on affiliative preferences before engaging in that act. As predicted, there was an overall preference for isolation when the act to be performed was embarrassing, and this tendency increased with anticipated surveillance. There was an overall preference for affiliation under fear arousal, and this preference also increased with anticipated surveillance. Contrary to previous research, whether or not the potential affiliate was a subject in the experiment (i.e., in a similar or dissimilar emotional state) did not affect these tendencies. Possible ways of accounting for these findings are discussed.
