Embodied Semantic Effects in Visual Word Recognition
Words have meanings; on that much, psycholinguists are generally agreed. However, the issue of what “meaning” is, and why a word’s semantic content affects how easily it is recognised, are matters of less consensus. Studies of visual word recognition typically ask participants to perform one of two key tasks: deciding whether a letter string is a valid word (lexical decision), or reading a word...
متن کاملAutomatic semantic feedback during visual word recognition.
Four experiments were conducted to determine whether semantic feedback spreads to orthographic and/or phonological representations during visual word recognition and whether such feedback occurs automatically. Three types of prime-target word pairs were used within the mediated-priming paradigm: (1) homophonically mediated (e.g.,frog-[toad]-towed), (2) orthographically mediated (e.g.,frog-[toad...
متن کاملSemantic interference in picture naming during dual-task performance does not vary with reading ability.
Previous dual-task studies examining the locus of semantic interference of distractor words in picture naming have obtained diverging results. In these studies, participants manually responded to tones and named pictures while ignoring distractor words (picture-word interference, PWI) with varying stimulus onset asynchrony (SOA) between tone and PWI stimulus. Whereas some studies observed no se...
متن کاملAutomaticity of phonological and semantic processing during visual word recognition
Reading involves activation of phonological and semantic knowledge. Yet, the automaticity of the activation of these representations remains subject to debate. The present study addressed this issue by examining how different brain areas involved in language processing responded to a manipulation of bottom-up (level of visibility) and top-down information (task demands) applied to written words...
متن کاملNonverbal Semantic Processing Disrupts Visual Word Recognition in Healthy Adults
Two experiments examined the effect of semantic interference on visual lexical decision (vLD) in normal skilled readers. Experiment 1 employed a dual-task paradigm to test whether nonverbal semantic processing disrupts visual word recognition when the orthographic structure of words and non-words is controlled. Experiment 2 employed the same paradigm to test whether participants strategically s...
