Contributions of semantic richness to the processing of idioms

AbstractIdiom studies typically consider variables such as familiarity, decomposability and literal plausibility, and the contributions of these to how figurative phrases are processed are well established. In this study we consider the effect of a previously untested variable: semantic richness. Semantic richness refers broadly to the range of semantic information denoted by a lexical item, and reflects features such as imageability, number of senses, semantic neighbourhood, etc. This has generally been restricted to single words and sometimes to metaphors, so here we investigate how some aspects of this measure – specifically those reflecting perceptual characteristics – contribute to the processing of idiomatic expressions. Results show that aspects of semantic richness affect idiom processing in different ways, with some (emotional valence) contributing to faster processing of figuratively related words, and others (those that highlight physical and literal aspects of the idiom) showing an inhibitory effect. We also show that for some of the dimensions of semantic richness considered here, there is a significant correlation between a measure constructed from the ratings of component words, and one gathered from ratings for the phrase as a whole, suggesting a straightforward way to operationalise semantic richness at a multiword level.

Increased reliance on a right hemispheric mechanism during idiom processing in adults with dyslexia

ABSTRACTPrevious studies on adults with dyslexia (DYS) have indicated difficulties in the comprehension of figurative language. Using the divided visual field paradigm, the present study investigated the hemispheric processing of idioms among 22 adults with DYS and 21 regular reader (RR) adults. Participants performed a lexical decision task for a target word related to either a literal or a figurative interpretation of an idiom. The results show that whereas the RR group demonstrated a bilateral pattern of hemispheric processing of idiomatic meanings, the DYS group showed a right hemisphere (RH) advantage. Furthermore, both groups demonstrated the typical RH advantage in processing the literal meanings of idioms. Our findings indicate increased recruitment of the RH in dyslexia, probably due to differences in cerebral language areas or weaker LH semantic processing.

Production of ambiguous idioms in English: A reading aloud study

In a reading‐aloud experiment, we investigated the on‐line processing of English idioms from a production perspective. The stimuli were ambiguous idioms used figuratively and literally, and matched novel control phrases. The analysis of the articulatory durations showed a processing advantage for idioms over controls. Further, we found that figurative meanings were articulated somewhat faster than their literal counterparts. The results suggest that the processing advantage for idioms over control phrases, previously reported in comprehension studies, is also present during their production. Unlike the comprehension idiom literature, however, the two idiom meanings might be processed differently during reading aloud. The study concludes with directions for future research, and a case is made for why this line of research is important for the field of applied linguistics.

Basic composition and enriched integration in idiom processing: An EEG study.

We investigated the extent to which the literal meanings of the words forming literally plausible idioms (e.g., break the ice) are semantically composed and how the idiomatic meaning is integrated in the unfolding sentence representation. Participants read ambiguous idiom strings embedded in highly predictable, literal, and idiomatic contexts while their EEG was recorded. Control sentences only contained the idiom-final word whose cloze values were as high as in literal and idiomatic contexts. Event-related potentials data showed that differences in the amplitude of a frontal positivity (PNP) emerged at the beginning and at the end of the idiom strings, with the idiomatic context condition associated with more positive voltages. The time frequency analysis of the EEG showed an increase in power of the middle gamma frequency band only in the literal context condition. These findings suggest that sentence revision mechanisms, associated with the frontal PNP, are involved in idiom meaning integration, and that the literal semantic composition of the idiomatic constituents, associated with changes in gamma frequency, is not carried out after idiom recognition.

Hemispheric processing of idioms in schizophrenia and autism spectrum disorder

ABSTRACTStudies conducted on individuals with schizophrenia (SZ) and autism spectrum disorder (ASD) show that they find it difficult to comprehend figurative language, and have a tendency to interpret it literally. This study examines hemispheric processing of idioms in patients with SZ, in comparison to individuals with ASD. Seventeen adults with SZ and 18 adults with ASD participated in the study. The two clinical groups were matched in age, vocabulary scores and verbal executive function scores. Using the divided visual field paradigm, the participants performed a lexical decision task for a target word related to either a literal or a figurative interpretation of an idiom. Whereas SZ patients showed the typical right lateralisation for non-salient literal interpretations of idioms, adults with ASD showed atypical bilateral processing. These findings indicate different hemispheric lateralisation in idiom processing in the two clinical groups.

The Real-Time Comprehension of Idioms by Typical Children, Children with Specific Language Impairment and Children with Autism.

ObjectiveWe examined on-line auditory idiom comprehension in typically developing (TD) children, children with specific language impairment (SLI), and children with autism. Theories of idiom processing in adults agree on a reliance on lexical/semantic memory for these forms, but differ in their specifics. The Lexical Representation hypothesis claims that literal and non-literal meanings are activated in parallel. The Configuration hypothesis claims that a non-literal meaning will take precedence, such that a literal meaning may not be activated at all.MethodChildren aged 6–16 years listened to sentences containing idioms for a cross-modal priming task. The idioms were ambiguous between an idiomatic and a literal meaning. We looked at priming for both meanings at the offset of the idiom.ResultsTD children (n=14) and children with SLI (n=7) primed for the idiomatic but not literal meaning of the idiom. Children with autism (n=5) instead primed for the literal but not idiomatic meaning.ConclusionsTD children showed an adult-like pattern, consistent with predictions of the Configuration Hypothesis. Children with SLI showed the typical pattern, whereas the atypical pattern observed for children with autism may reflect a particular deficit with complex material in semantic memory.

Bilingual and Monolingual Idiom Processing Is Cut from the Same Cloth: The Role of the L1 in Literal and Figurative Meaning Activation.

The present study examines non-native (L2) and native (L1) listeners' access to figurative idiomatic meaning and literal constituent meaning in two cross-modal priming experiments. Proficient German learners of English (L2) and native speakers of American English (L1) responded to English target words preceded by English idioms embedded in non-biasing prime sentences in a lexical decision task. English idioms differed in levels of translatability: Lexical level idioms had word-for-word translation equivalents in German, while post-lexical level idioms had matching idiomatic concepts in German but could not be translated word for word. Target words either related to the figurative meaning of the idiom or related to the literal meaning of the final constituent word of the idiom (e.g., to pull someone's leg, literal target: walk, figurative target: joke). Both L1 and L2 listeners showed facilitatory priming for literally- and figuratively-related target words compared to unrelated control target words, with only marginal differences between the listener groups. No effect of translatability was found; that is, the existence of word-for-word translation equivalents in German neither facilitated nor hindered meaning activation for German L2 listeners. The results are interpreted in the context of L1 and L2 models of idiom processing as well as further relevant translation studies.

The role of the ventro-lateral prefrontal cortex in idiom comprehension: An rTMS study

Previous research is equivocal with respect to the neural substrates of idiom processing. Particularly elusive is the role of the left ventro-lateral prefrontal cortex (VLPFC), a region implicated in semantic control generally. Although fMRI studies have shown that the left VLPFC is active during idiom processing (see Rapp et al. (2012), for review), rTMS studies have failed to corroborate a clear role of this prefrontal region (e.g., Oliveri et al., 2004).We investigated this issue using a semantic meaningfulness judgment task that compared idiom comprehension following rTMS-stimulation to the left VLPFC relative to a control site (vertex). We also investigated whether individual differences in general cognitive capacity among comprehenders modulated the effects of rTMS.The results indicate that left VLPFC stimulation particularly affected the processing of low-familiar idioms, possibly because these items involve a maximal semantic conflict between a salient literal and less-known figurative meaning. Of note, this pattern only emerged for comprehenders with higher cognitive control capacity, possibly because they were more likely to activate or maintain multiple semantic representations during idiom processing, which required VLPFC integrity. Taken together, the results support the importance of the left VLPFC to idiom processing.

"Going to town": Large-scale norming and statistical analysis of 870 American English idioms.

An idiom is classically defined as a formulaic sequence whose meaning is comprised of more than the sum of its parts. For this reason, idioms pose a unique problem for models of sentence processing, as researchers must take into account how idioms vary and along what dimensions, as these factors can modulate the ease with which an idiomatic interpretation can be activated. In order to help ensure external validity and comparability across studies, idiom research benefits from the availability of publicly available resources reporting ratings from a large number of native speakers. Resources such as the one outlined in the current paper facilitate opportunities for consensus across studies on idiom processing and help to further our goals as a research community. To this end, descriptive norms were obtained for 870 American English idioms from 2,100 participants along five dimensions: familiarity, meaningfulness, literal plausibility, global decomposability, and predictability. Idiom familiarity and meaningfulness strongly correlated with one another, whereas familiarity and meaningfulness were positively correlated with bothglobal decomposability and predictability. Correlations with previous norming studies are also discussed.

Hemispheric involvement in the processing of Chinese idioms: An fMRI study

Although the left hemisphere is believed to handle major language functions, the role of the right hemisphere in language comprehension remains controversial. Recently researchers have investigated hemispheric language processing with figurative language materials (e.g., metaphors, jokes, and idioms). The current study capitalizes on the pervasiveness and distinct features of Chinese idioms to examine the brain mechanism of figurative language processing. Native Chinese speakers performed a non-semantic task while reading opaque idioms, transparent idioms, and non-idiomatic literal phrases. Whole-brain analyses indicated strong activations for all three conditions in an overlapping brain network that includes the bilateral inferior/middle frontal gyrus and the temporo-parietal and occipital-temporal regions. The two idiom conditions elicited additional activations in the right superior parietal lobule and right precuneus. Item-based modulation analyses further demonstrated that activation amplitudes in the right angular gyrus, right superior parietal lobule and right precuneus, as well as left inferior temporo-occipital cortex, are negatively correlated with the semantic transparency of the idioms. These results suggest that both hemispheres are involved in idiom processing but they play different roles. Implications of the findings are discussed in light of theories of figurative language processing and hemispheric functions.

Salience effect on the processing of idioms in L1: Evidence from Malay simpulan Bahasa

Experimental investigations into figurative language processing have received little attention for languages other than English and several major European languages. Research on the Malay language, in particular, has been very limited. This study thus aimed to investigate the figurative language processing of familiar Malay idioms by L1 native speakers. Familiarity or salience is hypothesised as having a dominating effect in the processing of idiom meaning. This means, regardless of context or other possible factors, salience is said to determine processing advantage. A total of 24 participants completed a timed lexical-decision task after listening to idiomatic stimuli. Eight highly familiar idioms embedded in neutral sentences were used as auditory stimuli, and were paired visually together with either their figurative or literal meaning as target words. Results revealed a similar processing speed for responses to both literal and idiomatic meanings. Hence, it was concluded that the salience levels of both meanings are balanced in line with the Graded Salience Hypothesis.

Hemispheric Processing of Idioms and Irony in Adults With and Without Pervasive Developmental Disorder.

Previous studies on individuals with pervasive developmental disorders (PDD) have pointed to difficulties in comprehension of figurative language. Using the divided visual field paradigm, the present study examined hemispheric processing of idioms and irony in 23 adults with PDD and in 24 typically developing (TD) adults. The results show that adults with PDD were relatively unimpaired in understanding figurative language. While the TD group demonstrated a right hemisphere advantage in processing the non-salient meanings of idioms as well as the ironic endings of paragraphs, the PDD group processed these stimuli bilaterally. Our findings suggest that brain lateralization is atypical in adults with PDD. Successful performance along with bilateral brain activation suggests that the PDD group uses a compensation mechanism.

Individual differences in executive control relate to metaphor processing: an eye movement study of sentence reading.

Metaphors are common elements of language that allow us to creatively stretch the limits of word meaning. However, metaphors vary in their degree of novelty, which determines whether people must create new meanings on-line or retrieve previously known metaphorical meanings from memory. Such variations affect the degree to which general cognitive capacities such as executive control are required for successful comprehension. We investigated whether individual differences in executive control relate to metaphor processing using eye movement measures of reading. Thirty-nine participants read sentences including metaphors or idioms, another form of figurative language that is more likely to rely on meaning retrieval. They also completed the AX-CPT, a domain-general executive control task. In Experiment 1, we examined sentences containing metaphorical or literal uses of verbs, presented with or without prior context. In Experiment 2, we examined sentences containing idioms or literal phrases for the same participants to determine whether the link to executive control was qualitatively similar or different to Experiment 1. When metaphors were low familiar, all people read verbs used as metaphors more slowly than verbs used literally (this difference was smaller for high familiar metaphors). Executive control capacity modulated this pattern in that high executive control readers spent more time reading verbs when a prior context forced a particular interpretation (metaphorical or literal), and they had faster total metaphor reading times when there was a prior context. Interestingly, executive control did not relate to idiom processing for the same readers. Here, all readers had faster total reading times for high familiar idioms than literal phrases. Thus, executive control relates to metaphor but not idiom processing for these readers, and for the particular metaphor and idiom reading manipulations presented.

Effects of familiarity, context, and abstract representations on idiom processing in aphasia

Time-dependent effects of decomposability, familiarity and literal plausibility on idiom meaning activation

We address a core question about idioms relevant to formulaic language generally: are the figurative meanings of idioms directly retrieved or compositionally built? An understanding of this question has been previously obscured by the fact that idioms vary in ways that can affect processing, and also because experimental tasks, which differ across studies, probe different kinds of comprehension processes. We thus investigate how linguistic differences among idioms in semantic decomposability, familiarity, and literal plausibility modulate figurative meaning activation using cross-modal semantic priming, which is ideal for tracking activation of a particular target meaning over time. Across two experiments, we obtained two key findings. First, a comparison of different prime-target delay conditions suggests that figurative meaning activation steadily accrues as the idiom unfolds to 1000 ms later. Second, different linguistic attributes of idioms modulate figurative activation at different time points: increased literal plausibility interferes with idiom priming prior to the offset of the phrase, increased familiarity facilitates idiom priming at phrase offset, and increased semantic decomposability (surprisingly) interferes with idiom priming 1000 ms following phrase offset. These results contradict strong decompositional models of idiom processing and rather suggest that multiple linguistic factors jointly constrain figurative meaning retrieval in a time-dependent fashion.

Is the comprehension of idiomatic sentences indeed impaired in paranoid Schizophrenia? A window into semantic processing deficits.

Schizophrenia patients have been reported to be more impaired in comprehending non-literal than literal language since early studies on proverbs. Preference for literal rather than figurative interpretations continues to be documented. The main aim of this study was to establish whether patients are indeed able to use combinatorial semantic processing to comprehend literal sentences and both combinatorial analysis, and retrieval of pre-stored meanings to comprehend idiomatic sentences. The study employed a sentence continuation task in which subjects were asked to decide whether a target word was a sensible continuation of a previous sentence fragment to investigate idiomatic and literal sentence comprehension in patients with paranoid schizophrenia. Patients and healthy controls were faster in accepting sensible continuations than in rejecting non-sensible ones in both literal and idiomatic sentences. Patients were as accurate as controls in comprehending literal and idiomatic sentences, but they were overall slower than controls in all conditions. Once the contribution of cognitive covariates was partialled out, the response times (RTs) to sensible idiomatic continuations of patients did not significantly differ from those of controls. This suggests that the state of residual schizophrenia did not contribute to slower processing of sensible idioms above and beyond the cognitive deficits that are typically associated with schizophrenia.

Sticking your neck out and burying the hatchet: what idioms reveal about embodied simulation.

Idioms are used in conventional language twice as frequently as metaphors, but most research, particularly recent work on embodiment has focused on the latter. However, idioms have the potential to significantly deepen our understanding of embodiment because their meanings cannot be derived from their component words. To determine whether sensorimotor states could activate idiomatic meaning, participants were instructed to engage in postures/actions reflecting various idioms (e.g., sticking your neck out) relative to non-idiomatic control postures/actions while reading and responding to statements designed to assess idiomatic meaning. The results showed that statements were generally more strongly endorsed after idiom embodiment than control conditions, indicating that the meaning of idiomatic expressions may not be as disconnected from perceptual and motor experiences than previously thought. These findings are discussed in terms of the mirror neuron system and the necessity of pluralistic contributions from both sensorimotor and amodal linguistic systems to fully account for the representation and processing of idioms and other figurative expressions.

False memory for idiomatic expressions in younger and older adults: evidence for indirect activation of figurative meanings.

Idiomatic expressions can be interpreted literally or figuratively. These two meanings are often processed in parallel or very rapidly, as evidenced by online measures of idiomatic processing. Because in many cases the figurative meaning cannot be derived from the component lexical elements and because of the speed with which this meaning is accessed, it is assumed such meanings are stored in semantic memory. In the present study, we examined how literal equivalents and intact idiomatic expressions are stored in memory and whether episodic memory traces interact or interfere with semantic-level representations and vice versa. To examine age-invariance, younger and older adults studied lists of idioms and literal equivalents. On a recognition test, some studied items were presented in the alternative form (e.g., if the idiom was studied, its literal equivalent was tested). False alarms to these critical items suggested that studying literal equivalents activates the idiom from which they are derived, presumably due to spreading activation in lexical/semantic networks, and results in high rates of errors. Importantly, however, the converse (false alarms to literal equivalents after studying the idiom) were significantly lower, suggesting an advantage in storage for idioms. The results are consistent with idiom processing models that suggest obligatory access to figurative meanings and that this access can also occur indirectly, through literal equivalents.

An Empirical Study on Chinese EFL Learners’ Processing of English Animal Idioms

The present article reports on the effect of various animal idiom types and that of both proficiency levels on animal idiom comprehension. Based on the different match of equivalence/similarity and difference between surface linguistic forms and their underlying cultural connotations, a contrastive model for English and Chinese animal idioms is built, each distinguishing four possible combinations. Results of participants' performance on an English animal idioms comprehension test revealed that (a) The effects of English animal idiom types on idiom interpretation are significant. (b) The effects of English proficiency level on the comprehension of English animal idioms are significant, too. (c) During the processing of English animal idioms, L2 proficiency level and animal idiom types interact with each other and the interaction reached the level of significance.

Getting your wires crossed: Evidence for fast processing of L1 idioms in an L2

Monolingual speakers show priming for idiomatic sequences (e.g. a pain in the neck) relative to matched controls (e.g. a pain in the foot); single word translation equivalents show cross-language activation (e.g. dog–chien) for bilinguals. If the lexicon is heteromorphic (Wray, 2002), larger units may show cross-language priming in the same way as single words. We used the initial words of English idioms (e.g. to spill the. . . beans) and transliterated Chinese idioms (e.g. draw a snake and add. . . feet) as primes for the final words in a lexical decision task with high proficiency Chinese–English bilinguals and English monolinguals. Bilinguals responded to targets significantly faster when they completed a Chinese idiom (e.g. feet) than when they were presented with a matched control word (e.g. hair). The results are discussed in terms of conceptual activation and lexical translation processes, and are also incorporated into a dual route model of formulaic and novel language processing.
