Time-Varying Effective Connectivity during Visual Object Naming as a Function of Semantic Demands

Time-varying effective connectivity during visual object naming as a function of semantic demands.

Accumulating evidence suggests that visual object understanding involves a rapid feedforward sweep, after which subsequent recurrent interactions are necessary. The extent to which recurrence plays a critical role in object processing remains to be determined. Recent studies have demonstrated that recurrent processing is modulated by increasing semantic demands. Differentially from previous stu...

Picture-Induced Semantic Interference Reflects Lexical Competition during Object Naming

With a picture-picture experiment, we contrasted competitive and non-competitive models of lexical selection during language production. Participants produced novel noun-noun compounds in response to two adjacently displayed objects that were categorically related or unrelated (e.g., depicted objects: apple and cherry; naming response: "apple-cherry"). We observed semantic interference, with sl...

Brain Functional Connectivity Changes During Learning of Time Discrimination

The human brain is a complex system consist of connected nerve cells that adapts with and learn from the environment by changing its regional activities. Synchrony between these regional activities called functional network changes during the life, and with learning of new skills. Time perception and interval discrimination are among the most necessary skills for the human being to perceive mot...

Object and Action Naming: A Study on Persian-Speaking Children

Objectives: Nouns and verbs are the central conceptual linguistic units of language acquisition in all human languages. While the noun-bias hypothesis claims that nouns have a privilege in children’s lexical development across languages, studies on Mandarin and Korean and other languages have challenged this view. More recent cross-linguistic naming studies on children in German, Turkish,...
