Existing proposals on the attenuating uses of indirect, negated expressions (e.g., not happy to mean sad ) agree that speakers exploit indirectness for pragmatic purposes but differ on the underlying sources they attribute to these uses. Here, we synthesize existing proposals via adjective subjectivity, which operationalizes the notion of loopholes for plausible deniability. We present experimental evidence that the degree of subjectivity of an adjective predicts the degree to which participants strengthen the negated adjective’s meaning, but only if the adjective under consideration has an evaluatively-positive meaning. This finding indicates that speakers may intentionally use negation to leave themselves the option to retract the implicated face-threatening meaning if openly challenged.

Human behavioral choices can reveal intrinsic and extrinsic decision-influencing factors. We investigate the inference of choice priors in situations of referential ambiguity. In particular, we use the scenario of signaling games and investigate to which extent study participants profit from actively engaging in the task. Previous work has revealed that speakers are able to infer listeners’ choice priors upon observing ambiguity resolution. However, it was also shown that only a small group of participants was able to strategically construct ambiguous situations to create learning opportunities. This paper sets to address how prior inference unfolds in more complex learning scenarios. In Experiment 1, we examine whether participants accumulate evidence about inferred choice priors across a series of four consecutive trials. Despite the intuitive simplicity of the task, information integration turns out to be only partially successful. Integration errors result from a variety of sources, including transitivity failure and recency bias. In Experiment 2, we investigate how the ability to actively construct learning scenarios affects the success of prior inference and whether the iterative settings improve the ability to choose utterances strategically. The results suggest that full task engagement and explicit access to the reasoning pipeline facilitates the invocation of optimal utterance choices as well as the accurate inference of listeners’ choice priors.

From English to Hungarian to Mokilese, speakers exhibit strong ordering preferences in multi-adjective strings: “the big blue box” sounds far more natural than “the blue big box.” We show that an adjective’s distance from the modified noun is predicted not by a rigid syntax, but by the adjective’s meaning: less subjective adjectives occur closer to the nouns they modify. This finding provides an example of a broad linguistic universal—adjective ordering preferences—emerging from general properties of cognition.
