RESUMO
Linguistic communication builds on prelinguistic communicative gestures, but the ontogenetic origins and complexities of these prelinguistic gestures are not well known. The current study tested whether 8-month-olds, who do not yet point communicatively, use instrumental actions for communicative purposes. In two experiments, infants reached for objects when another person was present and when no one else was present; the distance to the objects was varied. When alone, the infants reached for objects within their action boundaries and refrained from reaching for objects out of their action boundaries; thus, they knew about their individual action efficiency. However, when a parent (Experiment 1) or a less familiar person (Experiment 2) sat next to them, the infants selectively increased their reaching for out-of-reach objects. The findings reveal that before they communicate explicitly through pointing gestures, infants use instrumental actions with the apparent expectation that a partner will adopt and complete their goals.

Story events are a psychological cause of emotional reactions, which in turn, motivate subsequent actions. This study addresses the degree of specificity of readers' inferences about fictional characters' emotions. In Experiment 1 (off-line), participants read short stories and selected the emotional term that was more consistent with the protagonist's emotion. Results indicated that participants tended to favor the specific emotional word. In Experiment 2 (on-line), reading times were longer when a target sentence described the protagonist in an emotional state that differed in family from the adequate emotional state, but belonged to the same class and valence of emotions, but no differences were found between emotions belonging to the same family. Overall, these results indicate that emotional inferences are more specific than valence and class, but not specific enough to differentiate subtleties within a family of emotions.
