Copyright © Lee, Miyata, & Ortega, 2008 A usage-based approach to overpassivization: The role of input and conceptualization biases Sang-Ki Lee, Munehiko Miyata, & Lourdes Ortega University of Hawai‘i at Mānoa SLRF 2008 Sunday, October 19th Overpassivization (1) *The most memorable experience of my life was happened 15 years ago. (Arabic L1; Zobl, 1989) (2) *Most of people are fallen in love and marry with somebody. (Japanese L1; Zobl, 1989) (3) *Rush hour traffic can be vanished because working at home is a new version. (Chinese L1; Yip, 1995) SLRF 2008 Overpassivization Why happen but never *is happened? “to happen” unaccusative verb: S(patient)+V(active) *Never occurs as transitive or in passive voice in the L1 SLRF 2008 Complications! Your Amazon.com order has shipped (#103-5354879-2596262) Greetings from Amazon.com. We thought you'd like to know that we shipped your item, and that this completes your order. Why not “Your Amazon.com order has been shipped” ?? “to ship” Used as transitive, active or passive Used as unaccusative, S(patient)+V(active) SLRF 2008 What L2 learners need to learn Intransitives can be of several types Unergatives: [S(agent)+Verb(action)] run, play... Unaccusatives (a.k.a. ergatives): S(patient)+Verb(active) Alternating unaccusatives: Ship, change, close... Non-alternating unaccusatives: happen, result... (Unaccusativity Hypothesis by Perlmutter, 1978) L2 developmental route: active passive overpassivization unaccusativity SLRF 2008 Studies of overpassivization are many: Free production data: Zobl (1989), Oshita (2000), Yip (1995) Elicited data (e.g., GJTs): Balcom (1997), Ju (2000), Hirawaka (2001), Kondo (2005), Sorace (1993, 1995; Sorace & Shomura, 2001), Montrul (1999, 2000, 2005), Zyzik (2006) Both: Han (2000, 2006) SLRF 2008 Explanations are diverse: Formal syntactic explanations: Prototypical semantic role+syntactic positions (Zobl, Yip, Oshita, Hirakawa, Montrul...) Cognitive linguistic explanations: Conceptualizable agents (Ju, Kondo) Usage-based explanations: (Zyzik) SLRF 2008 Usage-based L2 learning Two input biases: (Robinson & Ellis, 2008) Frequency Associative and emergent: L2 knowledge emerges from Alternation memory of instances/exemplars experienced. Input- and frequency-driven: What is learned reflects regularities in the input. One conceptual bias: Meaning-based and grounded: Knowledge is structured Causation by by world meanings as experienced by human body and mind. conceptualizable agent SLRF 2008 Input bias I – Frequency in the input Low-frequency verbs (e.g., c. 20- per million) High-frequency verbs (e.g., c. 100+ per million) Learners will find unaccusativity more difficult to judge in low-frequency verbs than in high-frequency verbs SLRF 2008 Input bias II – Types of alternation Alternating unaccusatives (“ship”-like verbs) Non-alternating unaccusatives (“happen”-like verbs) never appear in the input in the passive form Learners will find alternating verbs more difficult to judge than non-alternating verbs SLRF 2008 16 target verbs selected from Brown Corpus (Kucera & Francis, 1967) & American National Corpus (ANC) 2nd release (Reppen et al., 2005) 8 high-frequency verbs 4 alternating verbs (change, close, increase, turn) 4 non-alternating verbs (appear, happen, remain, result) 8 low-frequency verbs 4 alternating verbs (bounce, explode, scatter, shatter) 4 non-alternating verbs (glisten, glow, progress, vanish) SLRF 2008 Conceptual bias – Causation & conceptualizable agent (Ju, 2000): A fighter jet shot at the ship. External causation=agent More difficult to accept an External causation unaccusative, more tempting to overpassive The ship sank slowly. The rusty old ship started breaking up. The ship sank slowly. Internal causation SLRF 2008 Research questions RQ1: Will frequencies of unaccusative verbs (high versus low) affect L2 learners’ judgments of unaccusativity? RQ2: Will type of alternation (non-alternating versus alternating) affect L2 learners’ judgments of unaccusativity? RQ3: Will causation type (internal versus external) affect L2 learners’ judgments of unaccusativity? RQ4: Will the three factors interact? SLRF 2008 Participants - 63 adult learners of English with diverse L1 & major backgrounds - 10 English native speakers (baseline) Only the participants who had sufficient knowledge about English passivization - 56 learners (24 males & 32 females) Self-reported TOEFL score: M = 564.7 (SD = 57.2, min = 490, max = 667) - 10 native speakers (6 males & 4 females) SLRF 2008 Scaled Grammaticality Judgment Task (Bard, Robertson, & Sorace, 1996) low-frequency Example & non-alternating verb The magician did a trick with a coin. The coin was vanished instantly. LEAST ACCEPTABLE 1 2 external causation MOST ACCEPTABLE 3 4 5 6 SLRF 2008 Full design of scaled grammaticality judgment task 8 high-frequency verbs 4 alternating verbs 4 non-alternating verbs Each word generated two test items, one involving an external causation event and the other an internal causation event. 8 low-frequency verbs 4 alternating verbs Therefore, k = 52 4 non-alternating verbs 10 transitive predicates (distracters) SLRF 2008 Screening The reliability of the scaled GJT instrument was reasonable (Cronbach’s alpha: 0.84) ... The NS baseline data showed expected responses... So, we proceeded to analyze the NNS results SLRF 2008 Results Descriptive statistics for NNSs data Input frequency Types of unaccusatives Non-alternating High Alternating Alternating Non-alternating Low Low Alternating Alternating Causation types Mean cf.

IF = High/low frequency; U: Non-alternating/alternating; C = Internal/external SLRF 2008 Discussion RQ1: Main effect of input frequency (p = 0.01, eta2 = 0.15) High-frequency verbs > Low-frequency verbs It is likely that L2 learners had been exposed to the target verbs in the high-frequency group more often, so that they had built a more solid knowledge of the usage of those words. Usage-based approaches SLRF 2008 Discussion (cont’d) RQ2: Main effect of alternation type (p = 0.03, eta2 = 0.08) Non-alternating verbs > appear only as unaccusatives in active form in actual input Alternating verbs appear in active/ unaccusative/passive in actual input Accurate performance of L2 learners is influenced by their experience with the language input. Usage-based approaches SLRF 2008 Discussion (cont’d) RQ3: Non-significant main effect of causation type (p = 0.21, eta2 = 0.03) SLRF 2008 Discussion (cont’d) RQ4: Alternation type X Causation type (p = 0.03, eta2 = 0.08) Interactions? Yes, between alternation & causation: Having an internal causation (no agent) made the judging of non-alternating verbs easier. SLRF 2008 Conclusion • Facilitative effects of biases in the input: highfrequency and non-alternating exemplars were judged more accurately. • Conceptual bias may work only in interaction with input bias: when non-alternating verbs appeared in internal causation events, they were easier to accept as unaccusatives. SLRF 2008 Conclusion (cont’d) • Some support for the claim that things are learned first with high-frequency items (as in lexis-specific learning) and then the learning extends to low-frequency items and to more abstract constructions (as in construction-based generalization of patterns). • Usage-based approaches to SLA offer promising explanatory power in the study of the processing and subsequent development of linguistic knowledge of the L2.
