Deaf readers’ response to syntactic complexity: Evidence from self-paced reading

This study was designed to determine the feasibility of using self-paced reading methods to study deaf readers and to assess how deaf readers respond to two syntactic manipulations. Three groups of participants read the test sentences: deaf readers, hearing monolingual English readers, and hearing bilingual readers whose second language was English. In Experiment 1, the participants read sentences containing subject-relative or object-relative clauses. The test sentences contained semantic information that would influence online processing outcomes (Traxler, Morris, & Seely Journal of Memory and Language 47: 69–90, 2002; Traxler, Williams, Blozis, & Morris Journal of Memory and Language 53: 204–224, 2005). All of the participant groups had greater difficulty processing sentences containing object-relative clauses. This difficulty was reduced when helpful semantic cues were present. In Experiment 2, participants read active-voice and passive-voice sentences. The sentences were processed similarly by all three groups. Comprehension accuracy was higher in hearing readers than in deaf readers. Within deaf readers, native signers read the sentences faster and comprehended them to a higher degree than did nonnative signers. These results indicate that self-paced reading is a useful method for studying sentence interpretation among deaf readers.     

A failure to replicate rapid syntactic adaptation in comprehension

Language comprehension requires successfully navigating linguistic variability. One hypothesis for how listeners manage variability is that they rapidly update their expectations of likely linguistic events in new contexts. This process, called adaptation, allows listeners to better predict the upcoming linguistic input. In previous work, Fine, Jaeger, Farmer, and Qian (PLoS ONE, 8, e77661, 2013) found evidence for syntactic adaptation. Subjects repeatedly encountered sentences in which a verb was temporarily ambiguous between main verb (MV) and reduced relative clause (RC) interpretations. They found that subjects who had higher levels of exposure to the unexpected RC interpretation of the sentences had an easier time reading the RC sentences but a more difficult time reading the MV sentences. They concluded that syntactic adaptation occurs rapidly in unexpected structures and also results in difficulty with processing the previously expected alternative structures. This article presents two experiments. Experiment 1 was designed as a follow-up to Fine et al.’s study and failed to find evidence of adaptation. A power analysis of Fine et al.’s raw data revealed that a similar study would need double the items and four times the subjects to reach 95% power. In Experiment 2 we designed a close replication of Fine et al.’s experiment using these sample size guidelines. No evidence of rapid syntactic adaptation was found in this experiment. The failure to find evidence of adaptation in both experiments calls into question the robustness of the effect.     

Heroic or competent? A second look

Knight (1984, Organizational Behavior and Human Performance, 33, 307–322) has hypothesized that B. M. Staw and J. Ross's (1980, Journal of Applied Psychology, 65(3), 249–260) findings result from observers' perceptions of competent leadership rather than from observers' perceptions of heroic leadership. Although Knight's data support his position, Knight used experimental subjects and materials different from those of Staw and Ross. This study replicated Knight's experiment using subjects and materials like those of Staw and Ross. The results show clear support for competent theory and mixed support for heroic theory. They suggest that business experienced and business inexperienced subjects disagree upon the value of leaders who are heroic, optimizers, or satisficers, but agree that plodders are less desirable than any of the other three.     

The association between perceptions of daily experiences and self- and spouse-rated mood

A recent study by L. P. Rehm (Journal of Consulting and Clinical Psychology, 1978, 46, 854–859) reported strong associations between the daily report of pleasant and unpleasant events and a global mood rating. This study examined desirable and undesirable events in an effort to replicate and extend Rehm's work by having 26 married couples complete a daily event and mood checklist about husbands for 14 consecutive days. The group averaging strategy generally used to describe event-mood correlations was compared to a tabulation of significant individual correlations. The observed correlations were consistent with a previous study of pleasant events by P. M. Lewinsohn and M. Graf (Journal of Consulting and Clinical Psychology, 1973, 41, 261–268) and a study of unpleasant events by P. M. Lewinsohn and J. Talkington (Applied Psychological Measurement, 1979, 3, 83–101), yet were considerably smaller than those reported by Rehm. Wives' ratings of their husbands' mood revealed the same relationship with experiences as did husbands' self-rated mood. Differences in the populations studied and the event and mood assessments between our study and Rehm's could account for this finding. A tabulation approach to the data showed that few subjects actually achieved statistically significant associations in contrast to the group approach which indicated small associations across all subjects.     

SEMANTIC AND PHONOLOGICAL CODING PROCESSES IN SKILLED AND LESS SKILLED READERS' READING OF TEXT

Abstract

Two experiments examine the memory coding processes of skilled and less skilled readers during the reading of connected text. In experiment 1, students read several paragraphs which required a lexical decision about an underlined letter string within a sentence. Underlined letter strings were either synonyms, repeated words, or control words in reference to items in the sentence. Students were later asked to recall words related to their lexical decision, as well as verify the occurrence of sentences from the text. Skilled readers recalled more synonyms than poor readers, whereas no differences emerged between groups in their recall of other types of words related to the lexical task or for the verification of sentences. Experiment 2 procedures were similar to Experiment 1, except that synonyms were replaced with homophones and the sentence verification task included phrases related to the homophones. When compared to less skilled readers, skilled readers recalled more homophones and repeated words, but were more likely to be disrupted in correct verification of sentences with homophones. Taken together, the experiments suggest that along with phonological coding, semantic processing contributes an important amount of variance to deficiencies in the reading of connected text.     

A dual system for producing self-repairs in spontaneous speech: Evidence from experimentally elicited corrections

This paper presents a cognitive theory on the production and shaping of self-repairs during speaking. In an extensive experimental study, a new technique is tried out: artificial elicitation of self-repairs. The data clearly indicate that two mechanisms for computing the shape of self-repairs should be distinguished. One is based on the repair strategy called reformulation, the second one on lemma substitution. W. Levelt's (1983, Cognition, 14, 41–104) well-formedness rule, which connects self-repairs to coordinate structures, is shown to apply only to reformulations. In case of lemma substitution, a totally different set of rules is at work. The linguistic unit of central importance in reformulations is the major syntactic constituent; in lemma substitutions it is a prosodie unit, the phonological phrase. A parametrization of the model yielded a very satisfactory fit between observed and reconstructed scores. © 1987 Academic Press, Inc.     

Deaf signers and serial recall in the visual modality: Memory for signs,fingerspelling, and print

This study investigated serial recall by congenitally, profoundly deaf signers for visually specified linguistic information presented in their primary language, American Sign Language (ASL), and in printed or fingerspelled English. There were three main findings. First, differences in the serial-position curves across these conditions distinguished the changing-state stimuli from the static stimuli. These differences were a recency advantage and a primacy disadvantage for the ASL signs and fingerspelled English words, relative to the printed English words. Second, the deaf subjects, who were college students and graduates, used a sign-based code to recall ASL signs, but not to recall English words; this result suggests that well-educated deaf signers do not translate into their primary language when the information to be recalled is in English. Finally, mean recall of the deaf subjects for ordered lists of ASL signs and fingerspelled and printed English words was significantly less than that of hearing control subjects for the printed words; this difference may be explained by the particular efficacy of a speech-based code used by hearing individuals for retention of ordered linguistic information and by the relatively limited speech experience of congenitally, profoundly deaf individuals.     

The Neural Bases of Strategy and Skill in Sentence–Picture Verification

This experiment used functional Magnetic Resonance Imaging to examine the relation between individual differences in cognitive skill and the amount of cortical activation engendered by two strategies (linguistic vs. visual–spatial) in a sentence–picture verification task. The verbal strategy produced more activation in language-related cortical regions (e.g., Broca's area), whereas the visual–spatial strategy produced more activation in regions that have been implicated in visual–spatial reasoning (e.g., parietal cortex). These relations were also modulated by individual differences in cognitive skill: Individuals with better verbal skills (as measured by the reading span test) had less activation in Broca's area when they used the verbal strategy. Similarly, individuals with better visual–spatial skills (as measured by the Vandenberg, 1971, mental rotation test) had less activation in the left parietal cortex when they used the visual-spatial strategy. These results indicate that language and visual–spatial processing are supported by partially separable networks of cortical regions and suggests one basis for strategy selection: the minimization of cognitive workload.     

It Takes Two To Tango: Understanding and Acquiring Symmetrical Verbs

Children's ability to understand symmetrical verbs was investigated, along with adults' use of linguistic and visual cues to learn novel symmetrical verbs. Symmetrical verbs encode a relationship r between two entities such that X r Y entails Y r X. In Experiment 1, sixteen children (mean age 4;8) acted out two types of sentences with symmetrical and asymmetrical verbs. Eight adult judges viewed videotapes of the children's performance and tried to guess what sentence type was being enacted. Judges' performance was predicted(p < .05) by the verb type, symmetrical or asymmetrical. In Experiment 2, seventy-two adult subjects received visual and linguistic cues to the meanings of novel verbs. Both cue types affected subjects' judgments about whether the new verbs were symmetrical or asymmetrical (p < .05).     

Unilateral versus bilateral presentation methods in the reaction time paradigm

The use of bilateral presentation in lateralized tachistoscopic reaction time (RT) tasks has been precluded by problems of how to instruct the subject to respond to the left visual field (LVF) or right visual field (RVF) stimulus and by the necessity of fixation control with bilateral presentation. Schmuller and Goodman, 1979 and Schmuller and Goodman, 1980, Brain and Language, 11, 12–18) offered a method, applied to date only in recognition accuracy studies, which can overcome these problems. They used an “arrowhead pointer” at fixation. This instructs the subject as to which stimulus to report first and also controls fixation. We adapted the method to the RT paradigm by having subjects report only the stimulus indicated and applied it in a bilateral presentation version of the Object Naming Latency Task (W. F. McKeever & T. L. Jackson, 1979, Brain and Language, 7, 175–190). Fifty subjects received the unilateral task and 50 received the bilateral task. The bilateral task yielded right visual field superiority in 98% of the subjects and the magnitude of the superiority was over three times as large as in the unilateral task. Different sex × familial sinistrality × VHF interactions obtained on the tasks. Combining the advantages of reaction time and bilateral presentation methods may substantially increase the resolving power of lateralized tachistoscopic tasks.     

Rearing in response to a visual conditioned stimulus: An index of associative strength or of associability?

Two procedures for observing rearing behavior during a localized visual CS paired with an appetitive US were compared within subjects during classical conditioning and extinction procedures. When rearing was observed using the method and response definition described by P. C. Holland (1977, Journal of Experimental Psychology: Animal Behavior Processes, 3, 77–104), responding was acquired and maintained during conditioning trials in rats receiving paired presentations of the CS and US, but not in rats receiving the stimuli according to a “truly random” procedure. When rearing of the same rats was observed using the method and response definition described by H. Kaye and J. M. Pearce (1984, Journal of Experimental Psychology: Animal Behavior Processes, 10, 90–109), responding declined across conditioning trials in both groups. Furthermore, in extinction, rearing during the CS declined according to Holland's scoring method but was temporarily restored according to Kaye and Pearce's scoring. Observations of a second behavior, magazine responding, revealed essentially the same pattern of responding for both methods of scoring. These results support the position that the response criteria used by Holland and by Kaye and Pearce assess different components of behavior that occur in response to a visual CS, reflecting associative strength (i.e., a CR) and associability of the CS (i.e., an OR), respectively.

Fill the Gap! Combining Pragmatic and Prosodic Information to Make Gapping Easy

Two studies investigated the effects of prosody and pragmatic context on off-line and on-line processing of sentences like John greeted Paul yesterday and Ben today. Such sentences are ambiguous between the so-called ‘nongapping’ reading, where John greeted Ben, and the highly unpreferred ‘gapping’ reading, where Ben greeted Paul. In the first experiment, participants listened to dialogues and gave a speeded response as to which reading of an ambiguous target sentence first comes to mind. In the second experiment, they also responded to a visual probe that was presented during the presentation of the ambiguous target. The results show that context and prosody have independent and strong effects on both on-line processing and off-line interpretation of gapping; in the right combination they can make gapping as easy as the normally preferred nongapping reading.     

Some observations on the universality of the late-closure strategy

Two questionnaire studies and a reading time experiment investigated the application of the late-closure principle in Italian, a Romance language which contrasts with English with respect to several linguistic properties. All the studies addressed interpretation preferences in sentences containing a complex NP followed by a relative clause (e.g....the son of the woman who arrived yesterday...). While the questionnaires investigated final preferences, the reading time experiment addressed also the principle governing the initial attachment of a relative clause to a complex NP. Furthermore, through a manipulation of the type of preposition within the complex NP, we investigated the role of the thematic structure of the complex NP in initial and final parsing. The results showed that the late-closure principle applies in Italian to the initial parsing without being affected by the thematic structure of the complex NP. Final interpretation instead shows an effect of pragmatic preference and an effect of thematic structure on syntactic revisions. The results are discussed in terms of a parsing model that adopts syntactic parsing strategies and makes modular use of linguistic information. Some implications for the relationship between syntactic theories and the human parser are also addressed.     

Contextual control of negative transfer produced by prior CS-US pairings

When a conditioned stimulus (CS) is repeatedly paired with a weak unconditioned stimulus (US) prior to being paired with a stronger US in a second conditioning phase, interference, or negative transfer, is often observed during Phase 2. Two conditioned suppression experiments with rat subjects examined the effect of a context switch between phases in this “Hall-Pearce negative transfer paradigm.” In Experiment 1, negative transfer was obtained when the context remained the same for both phases, but there was no evidence of negative transfer when the context was switched between phases. Experiment 2 was designed to control for familiarity with the Phase 2 context, and showed that a context switch between phases again attenuated negative transfer. The effect of context on negative transfer was also similar to its effect on latent inhibition produced under comparable conditions. The results are not consistent with a model proposed by J. M. Pearce and G. Hall (Psychological Review, 87, 532–555, 1980), which ascribes no major role to the context in this situation, but are consistent with A. R. Wagner's (In S. H. Hulse, H. Fowler, & W. K. Honig, Eds., Cognitive Processes in Animal Behavior, pp. 177–209. Hillsdale NJ: Erlbaum, 1978) short-term memory model of conditioning, or with the view that contexts may signal specific CS-US relations. The results extend previous research on other interference paradigms, like latent inhibition and extinction, where context may play a similar role.     

Many-Valued Logic and Event-Related Potentials

In previous experiments on event-related potentials (ERPs) during linguistic judgments, the subjects' decisions have been categorical (e.g., true vs false). In this experiment, more realistic variations in truth value and subject certainty were used. Thirty-eight naive undergraduates read a story about a fictional murder. ERPs were recorded as the subjects rated the strength of their beliefs about statements relating to suspects in the crime. Because no subject was sure which of the suspects was guilty of committing the crime, binary (true–false) category judgments were inappropriate. Three components of the ERP waveforms were affected by the experimental manipulations. An early positive component was largest to sentences concerning the suspect considered most likely to have committed the crime. A subsequent broad posterior positivity (LPC) also showed significant sentence-type differences, but it was larger to sentences considered probable—whether they were true or false—than to more ambiguous sentences. A third ERP component (N400) was negative at midline electrode sites and peaked at approximately 420 ms. Subjects' truth-value judgments had no effect on the N400. N400 was, however, affected by the subject's task. It was more negative when subjects made graded judgments about truth value than when they made binary true–false judgments. Overall, naturalistic judgments of sentence validity produced a variety of brain responses that reflected different aspects of linguistic decision making.     

Possible effects of forced report order on tachistoscopic recognition of bilaterally presented stimuli: A response to Young and Ellis

Comparing visual field asymmetries for bilaterally presented words and corresponding line drawings, we found an RVF advantage for words and no visual field asymmetry for line drawings. We suggested that the RVF advantage previously obtained by Young, Bion, and Ellis (Brain and Language, 11, 54–65, 1980) for bilaterally presented line drawings may have resulted from a forced order of report procedure, noting that the RVF advantage was greater on trials on which subjects were forced to report in the nonpreferred right-to-left order. Young and Ellis (Brain and Language, 20, 166–171, 1983) attempt to discredit this claim and maintain their hypothesis that the RVF advantage for line drawings is attributable to better temporary storage of these stimuli by the left than the right hemisphere. In the present article, we present in greater detail our arguments for the effects of forced order of report on the perception of bilaterally presented stimuli and refute Young and Ellis's ibid. criticisms of this proposal.     

Meaning and learning: Response to Moerk

In response to Moerk (1986, Developmental Review, 6, 365–385) the following points are discussed: (a) Semantic and conceptual development must be conceived in terms of systems that undergo developmental change, (b) Objects are viewed as embedded in events and as being conceptualized first within a syntagmatic and later a paradigmatic system, (c) While the nature of the input to the child is important, its effects cannot be considered independently of the state of the child's conceptual and linguistic system. (d) The neurological considerations discussed by Moerk are not relevant to the particular developmental issues discussed in my book.
