Between “cost” and “default”: a new approach to Scalar Implicature

نویسنده

چکیده

Scalar Implicatures are pragmatic inferences that are normally derived in conversational exchanges when a scalar term, such as for example “or”, is used. Different theoretical accounts have been proposed to describe how and at which point in the derivation we actually add this inference. Large part of the most recent debate is focused on the question of the “cost” of implicature computation, an aspect that is crucial to choose among alternative accounts. In this perspective, my intent here is to present an experimental study in the ongoing debate centred on the “costly” or “default” nature of implicature computation. The main result of the study presented here is the fact that a “cost” is found only when the implicature is added despite the fact that it leads to a weakening of the overall assertion (namely, in DE contexts): this loss in informativity, and not implicature computation per se, is interpreted as the source of this “cost”. The theoretical background for this study is offered by Chierchia (2006) and his new intriguing parallelism between the phenomenon of scalar implicature and negative polarity.

Between “Cost” and “Default” of Scalar Implicature: the Cost of Embedding

Two main points constitute a matter of debate concerning the phenomenon of Scalar Implicatures (SIs): the place of their derivation, which opposes a “recursive”/grammatically driven approach such as Chierchia’s (Chierchia, 2002&2006; Fox, 2003; Landman, 1998; Levinson, 2000) to traditional NeoGricean approaches that view SIs as genuinely post-grammatical/pragmatic processes that are added “glob...

Electrophysiology of Pragmatic Processing: Exploring the Processing Cost of the Scalar Implicature in the Truth-Value Judgment Task

Most theoretical as well as empirical work regarding the scalar implicature not all of the quantifier some has focused on the controversy of whether this implicature is generated by default or based on context. Independently of this question, it can be also asked whether this scalar implicature contributes to the truth-conditional content of sentences. We present results of an ERP study which t...

Between “cost” and “default” of Scalar Implicature

The ongoing theoretical debate Scalar Implicatures (SIs) are pragmatic inferences that are normally derived in conversational exchanges when a scalar term is used. Different theoretical accounts have been proposed to explain how and when implicatures are derived. We will focus here on one particular aspect of this debate, namely, the question of the “cost” of implicature computation, which has ...

Distinguishing speed from accuracy in scalar implicatures

Scalar implicatures are inferences that arise when a weak expression is used instead of a stronger alternative. For example, when a speaker says, ‘‘Some of the children are in the classroom,’’ she often implies that not all of them are. Recent processing studies of scalar implicatures have argued that generating an implicature carries a cost. In this study we investigated this cost using a sent...

The cost of being cooperative: Details of the effort in processing scalar implicature

A long-standing open question concerns the cost or effort involved in processing scalar implicatures (SIs). When we hear “Some of the boxes are red”, we go beyond the literal meaning of “some” and infer that not all of the boxes are red. According to the Default view [1] hearers compute these kinds of SIs (generalized conversational implicatures) quickly, costlessly, and automatically. In contr...
