Le categorie linguistiche influenzano la percezione visiva
La BBC riferisce di uno studio dell'Università della California sul ruolo del linguaggio nei processi percettivi. Si tratta di un nuovo supporto all'approccio cognitivista, ispirato dalla versione morbida della nota ipotesi Sapir-Whorf sul rapporto tra pensiero e linguaggio.
Language affects 'half of vision'

Whorf hypothesis is supported in the right visual field but not the left
PNAS 2006 103: 489-494; published online before print as 10.1073/pnas.0509868103
ABSTRACT
The question of whether language affects perception has been debated largely on the basis of cross-language data, without considering the functional organization of the brain. The nature of this neural organization predicts that, if language affects perception, it should do so more in the right visual field than in the left visual field, an idea unexamined in the debate. Here, we find support for this proposal in lateralized color discrimination tasks. Reaction times to targets in the right visual field were faster when the target and distractor colors had different names; in contrast, reaction times to targets in the left visual field were not affected by the names of the target and distractor colors. Moreover, this pattern was disrupted when participants performed a secondary task that engaged verbal working memory but not a task making comparable demands on spatial working memory. It appears that people view the right (but not the left) half of their visual world through the lens of their native language, providing an unexpected resolution to the language-and-thought debate.
