Familiarity breeds dissent: Reliability analyses for British-English idioms on measures of familiarity, meaning, literality, and decomposability

Four hundred Greek idiomatic expressions: Ratings for subjective frequency, ambiguity, and decomposability

Idioms differ from other forms of figurative language because of their dimensions of subjective frequency, ambiguity (possibility of having a literal interpretation), and decomposability (possibility of the idiom's words to assist in its figurative interpretation). This study focuses on the Greek language and aims at providing the first corpus of 400 Greek idioms rated for their dimensions by 113 native Greek students, aged 19 to 39 years. The study aimed at (1) rating all idioms for their degree of subjective frequency, ambiguity, and decomposability, and (2) investigating the relationships between these dimensions. Three different assessments were conducted, during which the participants were asked to evaluate the degree of idioms' subjective frequency, ambiguity, and decomposability. The idioms were selected from a dictionary of Greek idioms titled "Dictionary of Idioms in Modern Greek" (Vlaxopoulos, 2007). This study resulted in the first database of Greek idioms assessed for their dimensions. The intraclass correlation coefficient (ICC) (two-way mixed, absolute agreement) demonstrated high internal consistency in the ratings given for each dimension, for the same idiom, by the different individual raters. Correlational analyses showed that subjective frequency was positively moderately correlated with decomposability, and positively weakly correlated with ambiguity, while decomposability was positively moderately correlated with ambiguity.

Old Dogs and New Tricks: Assessing Idiom Knowledge Amongst Native Speakers of Different Ages

Idioms, along with other formulaic multiword phrases, represent a substantial part of vocabulary knowledge. This study investigates how idiom knowledge develops through the adult lifespan, comparing familiarity and transparency ratings for a large set of common English idioms. A total of 237 participants, ranging from 18 to 77 years old, collectively rated 200 idioms. They also completed a short single-word vocabulary test and provided information about their educational background. Results showed a clear increase in idiom and single-word knowledge throughout the lifespan. For idioms, this represented a jump from the youngest age-group, then a steady increase from the age of around 25 onward. Single word vocabulary knowledge increased more evenly as a function of age. Perceptions of transparency were not affected in the same way. I discuss what these results suggest about the development of vocabulary through the lifespan.

The Elephant in the Room: A Systematic Review of Stimulus Control in Neuro-Measurement Studies on Figurative Language Processing

The processing of metaphors and idioms has been the subject of neuroscientific research for several decades. However, results are often contradictory, which can be traced back to inconsistent terminology and stimulus control. In this systematic review of research methods, we analyse linguistic aspects of 116 research papers which used EEG, fMRI, PET, MEG, or NIRS to investigate the neural processing of the two figurative subtypes metaphor and idiom. We critically examine the theoretical foundations as well as stimulus control by performing a systematic literature synthesis according to the PRISMA guidelines. We explicitly do not analyse the findings of the studies but instead focus on four primary aspects: definitions of figurative language and its subtypes, linguistic theory behind the studies, control for factors influencing figurative language processing, and the relationship between theoretical and operational definitions. We found both a lack and a broad variety in existing definitions and operationalisation, especially in regard to familiarity and conventionality. We identify severe obstacles in the comparability and validation potential of the results of the papers in our review corpus. We propose the development of a consensus in fundamental terminology and more transparency in the reporting of stimulus design in the research on figurative language processing.

Psycholinguistic and affective norms for 1,252 Spanish idiomatic expressions

This study provides psycholinguistic and affective norms for 1,252 Spanish idiomatic expressions. A total of 965 Spanish native speakers rated the idioms in 7 subjective variables: familiarity, knowledge of the expression, decomposability, literality, predictability, valence and arousal. Correlational analyses showed that familiarity has a strong positive correlation with knowledge, suggesting that the knowledge of the figurative meaning of an idiom is highly related to its frequency of use. Familiarity has a moderate positive correlation with final word predictability, indicating that the more familiar an idiom is rated, the more predictable it tends to be. Decomposability shows a moderate positive correlation with literality, suggesting that those idioms whose figurative meaning is easier to deduce from their constituents tend to have a plausible literal meaning. In affective terms, Spanish idioms tend to convey more negative (66%) than positive meanings (33%). Furthermore, valence and arousal show a quadratic relationship, in line with the typical U-shaped relationship found for single words, which means that the more emotionally valenced an idiom is rated, the more arousing it is considered to be. This database will provide researchers with a large pool of stimuli for studying the representation and processing of idioms in healthy and clinical populations.

Normative Data for Novel Nominal Metaphors, Novel Similes, Literal, and Anomalous Utterances in Polish and English

The two studies reported in the article provide normative measures for 120 novel nominal metaphors, 120 novel similes, 120 literal sentences, and 120 anomalous utterances in Polish (Study 1) and in English (Study 2). The presented set is ideally suited to addressing methodological requirements in research on metaphor processing. The critical (sentence-final) words of each utterance were controlled for in terms of their frequency per million, number of letters and syllables. For each condition in each language, the following variables are reported: cloze probability, meaningfulness, metaphoricity, and familiarity, whose results confirm that the sentences are well-matched. Consequently, the present paper provides materials that can be employed in order to test the new as well as existing theories of metaphor comprehension. The results obtained from the series of normative tests showed the same pattern in both studies, where the comparison structure present in similes (i.e., A is like B) facilitated novel metaphor comprehension, as compared to categorical statements (i.e., A is B). It therefore indicates that comparison mechanisms might be engaged in novel meaning construction irrespectively of language-specific syntactic rules.

Speedy Metonymy, Tricky Metaphor, Irrelevant Compositionality: How Nonliteralness Affects Idioms in Reading and Rating

It is widely acknowledged that fixed expressions such as idioms have a processing advantage over non-idiomatic language. While many idioms are metaphoric, metonymic, or even literal, the effect of varying nonliteralness in their processing has not been much researched yet. Theoretical and empirical findings suggest that metonymies are easier to process than metaphors but it is unclear whether this applies to idioms. Two self-paced reading experiments test whether metonymic, metaphoric, or literal idioms have a greater processing advantage over non-idiomatic control sentences, and whether this is caused by varying nonliteralness. Both studies find that metonymic and literal idioms are read significantly faster than controls, while the advantage for metaphoric idioms is only tenuous. Only experiment 2 finds literal idioms to be read fastest of all. As compositionality of the idioms cannot account for these findings, some effect of nonliteralness is suggested, together with idiomaticity and the sentential context.

Normative Data of Dutch Idiomatic Expressions: Subjective Judgments You Can Bank on

The processing of idiomatic expressions is a topical issue in empirical research. Various factors have been found to influence idiom processing, such as idiom familiarity and idiom transparency. Information on these variables is usually obtained through norming studies. Studies investigating the effect of various properties on idiom processing have led to ambiguous results. This may be due to the variability of operationalizations of the idiom properties across norming studies, which in turn may affect the reliability of the subjective judgements. However, not all studies that collected normative data on idiomatic expressions investigated their reliability, and studies that did address the reliability of subjective ratings used various measures and produced mixed results. In this study, we investigated the reliability of subjective judgements, the relation between subjective and objective idiom frequency, and the impact of these dimensions on the participants' idiom knowledge by collecting normative data of five subjective idiom properties (Frequency of Exposure, Meaning Familiarity, Frequency of Usage, Transparency, and Imageability) from 390 native speakers and objective corpus frequency for 374 Dutch idiomatic expressions. For reliability, we compared measures calculated in previous studies, with the D-coefficient, a metric taken from Generalizability Theory. High reliability was found for all subjective dimensions. One reliability metric, Krippendorff's alpha, generally produced lower values, while similar values were obtained for three other measures (Cronbach's alpha, Intraclass Correlation Coefficient, and the D-coefficient). Advantages of the D-coefficient are that it can be applied to unbalanced research designs, and to estimate the minimum number of raters required to obtain reliable ratings. Slightly higher coefficients were observed for so-called experience-based dimensions (Frequency of Exposure, Meaning Familiarity, and Frequency of Usage) than for content-based dimensions (Transparency and Imageability). In addition, fewer raters were required to obtain reliable ratings for the experience-based dimensions. Subjective and objective frequency appeared to be poorly correlated, while all subjective idiom properties and objective frequency turned out to affect idiom knowledge. Meaning Familiarity, Subjective and Objective Frequency of Exposure, Frequency of Usage, and Transparency positively contributed to idiom knowledge, while a negative effect was found for Imageability. We discuss these relationships in more detail, and give methodological recommendations with respect to the procedures and the measure to calculate reliability.

Idioms show effects of meaning relatedness and dominance similar to those seen for ambiguous words

Does the language comprehension system resolve ambiguities for single- and multiple-word units similarly? We investigate this question by examining whether two constructs with robust effects on ambiguous word processing - meaning relatedness and meaning dominance - have similar influences on idiom processing. Eye tracking showed that: (1) idioms with more related figurative and literal meanings were read faster, paralleling findings for ambiguous words, and (2) meaning relatedness and meaning dominance interacted to drive eye movements on idioms just as they do on polysemous ambiguous words. These findings are consistent with a language comprehension system that resolves ambiguities similarly regardless of literality or the number of words in the unit.

Idiom comprehension in aphasia: Literal interference and abstract representation

We investigate three potential mechanisms underlying the deficit in idiom comprehension seen in aphasia: difficulty inhibiting literal meanings, inability to recognize that a figurative interpretation is required, and difficulty processing abstract words and concepts. Unimpaired adults and PWA read high and moderate familiarity idioms either preceded or followed by a figuratively biasing context sentence. They then completed a string-to-word probe selection task, choosing between a figurative target, a literal lure, and unrelated concrete and abstract lures. PWA chose the figurative target more often for more familiar idioms and after figuratively biasing contexts, suggesting that difficulty accessing figurative meanings may be a key contributor to idiom impairment in aphasia. Importantly, PWA chose abstract lures at the same rate as they chose literal lures, suggesting that abstract lures may be considered equally good matches for weak idiomatic representations in PWA, and therefore that idiomatic figurative meanings may be represented similarly to abstract concepts for PWA. These results have implications for models of idiom comprehension in aphasia, as well as the design of future studies of idiom comprehension in PWA.

Psycholinguistic norms for 320 fixed expressions (idioms and proverbs) in French

We provide psycholinguistic norms for a new set of 160 French idiomatic expressions and 160 proverbs: knowledge, predictability, literality, compositionality, subjective and objective frequency, familiarity, age of acquisition (AoA) and length. Different analyses (reliability, descriptive statistics and correlations) performed on the norms are reported and discussed. The norms can be downloaded as Supplemental Material .

"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 both global decomposability and predictability. Correlations with previous norming studies are also discussed.

Normative data for idiomatic expressions

Idiomatic expressions such as kick the bucket or go down a storm can differ on a number of internal features, such as familiarity, meaning, literality, and decomposability, and these types of features have been the focus of a number of normative studies. In this article, we provide normative data for a set of Bulgarian idioms and their English translations, and by doing so replicate in a Slavic language the relationships between the ratings previously found in Romance and Germanic languages. Additionally, we compared whether collecting these types of ratings in between-subjects or within-subjects designs affects the data and the conclusions drawn, and found no evidence that design type affects the final outcome. Finally, we present the results of a meta-analysis that summarizes the relationships found across the literature. As in many previous individual studies, we found that familiarity correlates with a number of other features; however, such studies have shown conflicting results concerning literality and decomposability ratings. The meta-analysis revealed reliable relationships of decomposability with a number of other measures, such as familiarity, meaning, and predictability. Conversely, literality was shown to have little to no relationship with any of the other subjective ratings. The implications for these relationships in the context of the wider experimental literature are discussed, with a particular focus on the importance of attaining familiarity ratings for each sample of participants in experimental work.
