This study explores the English it-cleft construction and its components. It examines hypotheses, empirical studies, and general discussions regarding the presence of an antecedent and contrastiveness in cleft sentences.

Outline • Hypotheses • Empirical studies • General discussion
The English it-cleft (1) It’s John who cooked beans. Often conceived as identificational focus (Kiss 1998), with the following standard components:
Hypotheses • The standard components suffice. • In addition to to the standard components, an antecedent in prior discourse(corresponding to a focal alternative à la Rooth) is required. • A contrastiveness requirement must be added to the standard components.
Evidence for Hypothesis B (2) A: Sarah looks good with glasses! B: #Yeah, it was Boots she got them from. B:Yeah, she got them from Boots. (3) A: Sarah just got some glasses from Vision Express. B: No, it was Boots she got them from B: No, she got them from Boots. These examples do not differ wrt to the standard components, but rather the presence of an antecedent (Rooth1992; Schwarschild 1999)
Evidence for Hypothesis C? Even an antecedent is not enough for a cleft to be perfectly felicitous (Destruel & Vellemann 2014): (4) A: Where did Sarah get those glasses? B: # I think it was Boots she got them from. B: I think she got them from Boots.
Contrastiveness • Zimmermann 2008: “contrastivity… means that a particular focus content or a particular speech act containing a focus is unexpected for the hearer from the speaker’s perspective”. • Extrapolating: The more commitment the hearer has displayed to a contrary claim, the more likely contrastive marking is.

Idea to test The more strongly the interlocutor appears committed to a (false) proposition, the better it is to repudiate them with a cleft.
Example stimuli Weak commitment context A: Mark just bought a very ugly car. And it looks like it's about to fall apart. I guess Leah convinced him to buy it. Strong commitment context A: Mark just bought a very ugly car. And it looks like it's about to fall apart. Leah convinced him to buy it. Responses (same for both contexts) B: Actually, it’s Linda who convinced him to buy it. (cleft) B’: Actually, Linda who convinced him to buy it. (SVO)
Contexts 1, 3, 5, 7 - CONTRADICT + CONTRADICT
Subject vs. non-subject Context with non-subject focus: A: Look at John this evening. He’s all dressed up. I guess he is going out with Tammy. B: Actually, he is going out with Karen. B’: Actually, it’s Karen he’s going out with.
Design • 6 contexts x 2 grammatical functions (subject vs. non-subj)= 12 lexicalizations • 12 lexicalizations x 12 items= 144 experimental dialogues • Counterbalanced across 12 lists;each participant saw 24 items (12 subj, 12 non-subj). • Order pseudo-randomized among 24 fillers.
Three studies • Pre-test 1: strength of existential inference • Pre-test 2: strength of commitment • Main study • All used the exact same material,except only A’s part was presented in pre-tests. • 3 different groups of participants.
Pre-test studies #1 & #2 1. Strength of existential inference: How strongly does A believe `someone V-ed’? 2. Strength of commitment: How committed is Speaker A to `Subj V-ed’?
Pre-test #1: Strength of existential inference Speaker A: Mark just bought a very ugly car. And it looks like it's about to fall apart. I guess Leah convinced him to buy it. On a scale from 1-7, how likely is it that someone convinced Mark to buy a very ugly car? (1-Extremely unlikely, 7-Extremely likely) 1 2 3 4 5 6 7
Good news! • The contradictory contexts (2-6) don’tdiffer significantly from each other with respect to Speaker A’s commitment to existence. • So, if these contexts differ in the strength of A’s commitment to a statement that B will contradict (as they were designed to do), then we can test our prediction.
Pre-test #2:Strength of commitment • Question: How strongly is A committed to the target proposition? • 4 designed levels of commitment strength: • Non-contradictory • Weak • Strong • Presuppositional Increasingly stronger commitment
Pre-test #2: Procedure Speaker A: Mark just bought a very ugly car. And it looks like it's about to fall apart. I guess Leah convinced him to buy it. On a scale from 1-7, how strongly is Speaker A committed to the fact that Leah convinced Mark to buy a very ugly car? (1-Extremely not committed, 7-Extremely committed) 1 2 3 4 5 6 7
More good news! • Recall: Contradictory contexts (2-6) all provide an antecedent and commit Speaker A to existence. • But, crucially, they differ in the strength of A’s commitment to a statement that B will contradict. • So we can test our prediction (Hypothesis C).
Main study • Conducted on MTurkplatform (N= 64) • Measured naturalness of B’s response. • Independent variables: • Contrastiveness (commitment * contradiction) • Existential • At-issueness • Grammatical function
Measuring contrastiveness • In non-contradictory contexts, items have a contrastiveness value of 0. • In contradictory contexts, the contrastiveness value for an item is the strength of Speaker A’s commitment to the conflicting proposition (as measured in pre-test #2). Contrastiveness = Commitment * Contradiction
Non-contradictory contexts Contradictory contexts
Models for dataset with clefts**random effects were also included 1: Judgment ~ Grammatical function (ns.) 2: Judgment ~ At-issueness(ns.) 3: Judgment ~ Contrastiveness(t = 17.36) 4: Judgment ~ Existential (t = 14.8) 5: Judgment ~ Contrastiveness+Existential (better than 4;χ2 = 69.5, p < 0.001)
Conclusion for clefts Contrastiveness improves the acceptability of cleft sentences, independently of whether the existential presupposition is satisfied.
Non-contradictory contexts Contradictory contexts
Models for dataset with canonicals**random effects were also included 1: Judgment ~ Grammatical function (ns.) 2: Judgment ~ At-issueness(ns.) 3: Judgment ~ Contrastiveness(t = -5.24) 4: Judgment ~ Existential (ns.) 5: Judgment ~ Contrastiveness+Existential (not better than model 4;χ2 = 1.39, p = 0.23)
Outline • Hypotheses • Empirical studies • General discussion
General discussion • We have experimentally operationalized a notion of contrastivenessthat relates to how strongly the addressee believes the contrary. • We have shown that this factor significantly improves clefts, in contrast to canonicals, controlling for other factors known to influence the acceptability of clefts. • Not captured by any existing model of clefts.
