The development of idiom comprehension: an investigation of semantic and contextual processing skills

Two experiments compared 7- and 8-year-olds' and 9- and 10-year-olds' ability to use semantic analysis and inference from context to understand idioms. We used a multiple-choice task and manipulated whether the idioms were transparent or opaque, familiar or novel, and presented with or without a supportive story context. Performance was compared with that of adults (Experiment 1) and 11- and 12-year-olds (Experiment 2). The results broadly support Cacciari and Levorato's global elaboration model of figurative competence with a notable exception: Even the youngest children were able to use semantic analysis to derive the meanings of transparent idioms as well as being sensitive to meaning in context. The findings show that young children process language at both the small-grain phrase level and the discourse level to establish figurative meaning, and they demonstrate that the language processing skills that aid idiom comprehension, as well as idiom knowledge itself, are still not fully developed in 11- and 12-year-olds.     

Lexical Acquisition in Probable Alzheimer''s Disease

Patients with probable Alzheimer's disease (pAD) were exposed to a new verb in a naturalistic fashion. We probed their knowledge of the word's semantic and grammatical characteristics for several minutes following this exposure, and compared this with their performance on parallel measures assessing known words. Significant differences were seen between pAD patients and controls in the acquisition of the new verb's semantic meaning and its argument structure, but pAD patients did not differ from controls in the acquisition of the new word's grammatical form class. Individual patient analyses demonstrated parallel deficits restricted to the semantic meaning and argument structure of the new word and known words in several pAD patients, suggesting that a selective language impairment contributed to their word learning deficit. This pattern is consistent with an intimate relationship between semantic meaning and argument structure in semantic memory. Other pAD patients had difficulty learning about all aspects of the new word, despite good performance with known words, suggesting that compromised memory may have limited their lexical acquisition.     

惯用语理解的多种心理机制：不同的证据

惯用语的理解机制一直是心理语言学研究的热点问题。来自语言学和神经生理学的证据都表明,对惯用语的加工存在多样化趋势,而且加工策略和手段会随个体卷入社会生活的程度而变化。惯用语的加工受加工者自身的隐喻知识以及惯用语本身性质的影响。另外,惯用语加工激活的脑区表明句法和语义分析在惯用语理解中均发挥重要作用,惯用语并没有词汇化,但是不能使用统一的加工模型来整合惯用语的理解机制。惯用语自身性质的多样化导致惯用语理解的多种心理机制。     

Short-term retention of lexical-semantic representations: implications for speech production

Patients with semantic STM deficits have difficulty comprehending sentences that require the retention of several lexical-semantic representations prior to their integration into higher-level propositions (Martin, 1995: Martin & Romani. 1994). In Experiment 1, patients with a semantic retention deficit had difficulty with the same type of constructions in speech production, namely noun phrases with one or two prenominal adjectives. Their performance improved when they could produce the nouns and adjectives in sentence form, which placed smaller demands on lexical-semantic retention. In Experiment 2 these patients were better able to produce syntactically complex sentences than the prenominal adjective phrases having an equal number of content words, indicating that the findings in Experiment 1 could not be attributed to syntactic complexity. These patients produced more pauses in the sentence constructions in Experiments 1 and 2, suggesting that the timing of such productions is abnormal. In contrast, patient EA, with a phonological retention deficit, performed better than the patients with a semantic retention deficit on the AN phrases despite having a smaller STM span. She showed no significant benefit of producing sentence compared to phrase constructions, and also made fewer and shorter pauses than the other patients. These findings support the multiple capacities view of verbal working memory and suggest that the same semantic retention capacity used in language comprehension is used in speech production.     

Language Abilities in Children with Attention Deficit Hyperactivity Disorder, Reading Disabilities, and Normal Controls

Research has demonstrated a high prevalence of language impairments (LI) and reading disabilities (RD) in children with attention deficit hyperactivity disorder (ADHD). Since RD is also associated with LI, it is unclear whether the language impairments are specific to ADHD or associated with comorbid RD. The language abilities of ADHD children with and without RD were investigated in a task requiring recall of a lengthy narrative, and in tests assessing knowledge of the semantic aspects of language. The study was conducted with 50 boys—14 ADHD, 14 ADHD + RD, 8 RD, and 14 normal controls, aged 7 to 11. Children with ADHD (ADHD-only, ADHD + RD) exhibited difficulties in organizing and monitoring their story retelling. Children with RD (RD-only, ADHD + RD) demonstrated deficits in receptive and expressive semantic language abilities on the language processing tests. The comorbid group (ADHD + RD) exhibited the deficits of both ADHD and RD children. The deficiencies of ADHD children are consistent with higher-order executive function deficits while the deficits of RD children are consistent with deficits in the basic semantics of language processing.     

Comprehension and memory of the literal and figurative meaning of proverbs

Proverbs were used to examine recognition memory for four types of sentence information (figurative meaning, literal meaning, lexical information, syntactic information) with two levels of comprehension. Forced-choice recognition tasks showed that subjects were successful in remembering all four types of information. Recognition scores for the figurative meaning of unfamiliar proverbs presented in isolation were above chance and were also significantly improved when procedures were employed which encouraged comprehension of this level of meaning. The results are most consistent with theories of comprehension which provide for different types of processing for figurative and literal language.     

Speakers' assumptions about the lexical flexibility of idioms

In three experiments, we examined why some idioms can be lexically altered and still retain their figurative meanings (e.g., John buttoned his lips about Mary can be changed into John fastened his lips about Mary and still mean "John didn't say anything about Mary"), whereas other idioms cannot be lexically altered without losing their figurative meanings (e.g., John kicked the bucket, meaning "John died," loses its idiomatic meaning when changed into John kicked the pail). Our hypothesis was that the lexical flexibility of idioms is determined by speakers' assumptions about the ways in which parts of idioms contribute to their figurative interpretations as a whole. The results of the three experiments indicated that idioms whose individual semantic components contribute to their overall figurative meanings (e.g., go out on a limb) were judged as less disrupted by changes in their lexical items (e.g., go out on a branch) than were nondecomposable idioms (e.g., kick the bucket) when their individual words were altered (e.g., punt the pail). These findings lend support to the idea that both the syntactic productivity and the lexical makeup of idioms are matters of degree, depending on the idioms' compositional properties. This conclusion suggests that idioms do not form a unique class of linguistic items, but share many of the properties of more literal language.     

Later language development in narratives in children with perinatal stroke

Studies of young children with unilateral perinatal stroke (PS) have confirmed the plasticity of the developing brain for acquiring language. While recent studies of typically developing children have demonstrated the significant development of language well into adolescence, we know little regarding the course of language development in the PS group as they mature. Will children with PS continue to show the same remarkable plasticity that they exhibited at younger ages? In the present paper we investigate later language and discourse in children with perinatal stroke (ages 7–16) using spoken personal narrative as the discourse context. In contrast to the findings of the discourse studies of younger children with PS, children with left hemisphere lesions made more morphological errors, used less complex syntax and fewer syntactic types than controls; they also produced more impoverished story settings. In contrast, those with right hemisphere lesions performed comparably to controls, except in their impoverished use of complex syntax. The findings provide insight into the nature of later spoken language development in these children, revealing both the nature and extent of neuroplasticity for language as well as potential regional biases.     

The muddy waters of idiom comprehension

Target sentences containing familiar and less familiar idioms used either literally or figuratively or containing no idioms were presented repeatedly for 100 msec per presentation. Each sentence was preceded by a short paragraph. The number of presentations required to read each target sentence and the cued recall of those target sentences containing idioms were recorded. Control sentences required fewer presentations to be read than all sentences except those with less familiar idioms used literally. Sentences with less familiar idioms used literally required fewer presentations to be read than those with less familiar idioms used figuratively and those with familiar idioms used literally. Familiar idioms were recalled significantly more often than less familiar idioms. The results of this study were unexpected and a model of idiom comprehension incorporating these results and those of other researchers is proposed. This model suggests that idioms fall along continuums of figurative meaning familiarity and literal meaning likelihood, and that their positions along these continuums determines whether the figurative or the literal meaning is processed initially.

Exploring the contribution of the cerebral hemispheres to language comprehension deficits in adults with developmental language disorder

A divided visual field, priming paradigm was used to observe how adults who have a history of developmental language disorder (DLD) access lexically ambiguous words. The results show that sustained semantic access to subordinate word meanings (such as BANK-RIVER), which is seen in control subjects, is disrupted in the right cerebral hemisphere for this special population of readers. In the left hemisphere, only the most dominant meaning of the ambiguous word shows sustained priming in both controls and DLD participants. Therefore, for the DLD readers the subordinate meanings of words are not primed in either hemisphere and, thus, may not be available during online processing and integration of discourse. This right hemisphere lexical access deficit might contribute to the language comprehension difficulties exhibited by adult readers with a history of DLD.     

COGNITIVE PROFILES OF READING-DISABLED CHILDREN:

Abstract— A comprehensive cognitive appraisal of elementary school children with learning disabilities showed that within the language sphere, deficits associated with reading disability are selective. Phonological deficits consistently accompany reading problems whether they occur in relatively pure form or in the presence of coexisting attention deficit or arithmetic disability. Although reading-disabled children were also deficient in production of morphologically related forms, this difficulty stemmed in large part from the same weakness in the phonological component that underlies reading disability. In contrast, tests of syntactic knowledge did not distinguish reading-disabled children from those with other cognitive disabilities, nor from normal children after covarying for intelligence.     

Processing homonymy and polysemy: effects of sentential context and time-course following unilateral brain damage

The present study investigated the abilities of left-hemisphere-damaged (LHD) non-fluent aphasic, right-hemisphere-damaged (RHD), and normal control individuals to access, in sentential biasing contexts, the multiple meanings of three types of ambiguous words, namely homonyms (e.g., "punch"), metonymies (e.g., "rabbit"), and metaphors (e.g., "star"). Furthermore, the predictions of the "suppression deficit" and "coarse semantic coding" hypotheses, which have been proposed to account for RH language function/dysfunction, were tested. Using an auditory semantic priming paradigm, ambiguous words were incorporated in dominant- or subordinate-biasing sentence-primes followed after a short (100 ms) or long (1,000 ms) interstimulus interval (ISI) by dominant-meaning-related, subordinate-meaning-related or unrelated target words. For all three types of ambiguous words, both the effects of context and ISI were obvious in the performance of normal control subjects, who showed multiple meaning activation at the short ISI, but eventually, at the long ISI, contextually appropriate meaning selection. Largely similar performance was exhibited by the LHD non-fluent aphasic patients as well. In contrast, RHD patients showed limited effects of context, and no effects of the time-course of processing. In addition, although homonymous and metonymous words showed similar patterns of activation (i.e., both meanings were activated at both ISIs), RHD patients had difficulties activating the subordinate meanings of metaphors, suggesting a selective problem with figurative meanings. Although the present findings do not provide strong support for either the "coarse semantic coding" or the "suppression deficit" hypotheses, they are viewed as being more consistent with the latter, according to which RH damage leads to deficits suppressing alternative meanings of ambiguous words that become incompatible with the context.     

Coh-Metrix: Analysis of text on cohesion and language

Advances in computational linguistics and discourse processing have made it possible to automate many language- and text-processing mechanisms. We have developed a computer tool called Coh-Metrix, which analyzes texts on over 200 measures of cohesion, language, and readability. Its modules use lexicons, part-of-speech classifiers, syntactic parsers, templates, corpora, latent semantic analysis, and other components that are widely used in computational linguistics. After the user enters an English text, Coh-Metrix returns measures requested by the user. In addition, a facility allows the user to store the results of these analyses in data files (such as Text, Excel, and SPSS). Standard text readability formulas scale texts on difficulty by relying on word length and sentence length, whereas Coh-Metrix is sensitive to cohesion relations, world knowledge, and language and discourse characteristics.     

A critique of Mark D. Allen's "the preservation of verb subcategory knowledge in a spoken language comprehension deficit"

Allen [Allen, M. (2005). The preservation of verb subcategory knowledge in a spoken language comprehension deficit. Brain and Language, 95, 255-264.] reports a single patient, WBN, who, during spoken language comprehension, is still able to access some of the syntactic properties of verbs despite being unable to access some of their semantic properties. Allen claims that these findings challenge linguistic theories which assume that much of the syntactic behavior of verbs can be predicted from their meanings. I argue, however, that this conclusion is not supported by the data for two reasons: first, Allen focuses on aspects of verb syntax that are not claimed to be influenced by verb semantics; and second, he ignores aspects of verb syntax that are claimed to be influenced by verb semantics.     

The comprehension of idioms

Four experiments will performed to examine how familiar idioms are interpreted. Subjects had to respond as rapidly as possible whether an idiom had the same or different meaning as a phrase which, on half of the trials, was a paraphrase of either the figurative or literal meaning of the idiom. When subjects were instructed to respond on the basis of either figurative or literal meaning, idioms were matched to their literal and figurative paraphrases equally rapidly. When subjects were instructed to respond only on the basis of literal meaning, idiom-phrase pairs that shared a figurative interpretation took longer to reject as different than idiom pairs that shared no interpretation. These results domonstrated that whenever a familiar idiom is comprehended, both its literal and figurative interpretations are made.     

Electrophysiological and behavioral measures of the influence of literal and figurative contextual constraints on proverb comprehension

Proverbs tend to have meanings that are true both literally and figuratively (i.e., Lightning really doesn't strike the same place twice). Consequently, discourse contexts that invite a literal reading of a proverb should provide more conceptual overlap with the proverb, resulting in more rapid processing, than will contexts biased towards a non-literal reading. Despite this, previous research has failed to find the predicted processing advantage in reading times for familiar proverbs when presented in a literally biasing context. We investigate this issue further by employing both ERP methodology and a self-paced reading task and, second, by creating an item set that controls for problems with items employed in earlier studies. Our results indicate that although people do not take longer to read proverbs in the literally and proverbially biasing contexts, people have less difficulty integrating the statements in literal than figurative contexts, as shown by the ERP data. These differences emerge at the third word of the proverbs.
