Crosslinguistic Causatives

•  Prediction: The greater the extent to which a particular event scores higher on the event-merge measure, the greater the likelihood that

•  (a) languages will lexicalise this event with a causative-only / causative-basic verb (i.e., the less transparent / predictable / regular the causative form will be)

Crosslinguistic Causatives

•  Prediction: The greater the extent to which a particular event scores higher on the event-merge measure, the greater the likelihood that

•  (b) children will correctly prefer an irregular/vowel change/lexical form over a regular/periphrastic/morpho- syntactic form in judgments/production

Crosslinguistic Causatives

We also plan to use three other semantic predictors from Shibatani and Pardeshi: 1. We are interested in how A would usually cause this type ACTION/ EVENT/ CHANGE. On a scale from 1-100, please rate the extent to which A … can ensure that the ACTION/EVENT/CHANGE happens by physically manipulating B (higher numbers)… … can only ask/tell/instruct B to undergo the ACTION/EVENT/CHANGE (lower numbers)

On a scale from 1-100, please rate the extent to which…. …B chooses to carry out/undergo the ACTION/EVENT/CHANGE (lower numbers) VERSUS …A forces B to carry out/undergo the ACTION/EVENT/CHANGE, whether B likes it or not (higher numbers)

We also plan to use three other semantic predictors from Shibatani and Pardeshi: 3. We are interested in the extent to which A is necessary in bringing about this ACTION/EVENT/CHANGE. On a scale from 1-100, please rate the extent to which…. …B's ACTION/EVENT/CHANGE could come about with absolutely no involvement from A (lower numbers) VERSUS …B's ACTION/EVENT/CHANGE requires A's involvement, and could not happen without A (higher numbers)
