Perceptual differentiation as a source of category effects in object processing: Evidence from naming and object decision

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,...

Perceptual differentiation and category effects in normal object recognition: a PET study.

The purpose of the present PET study was (i) to investigate the neural correlates of object recognition, i.e. the matching of visual forms to memory, and (ii) to test the hypothesis that this process is more difficult for natural objects than for artefacts. This was done by using object decision tasks where subjects decided whether pictures represented real objects or non-objects. The object de...

Infants' object category formation and use: Real-world context effects on category use in object processing

Object Naming and Object Composition

In this paper, we show that a flat domain of object names is inappropriate in the context of object composition since new naming requirements must be fulfilled. These requirements can be summarized by: (1) visibility and hiding of components, (2) checking whether two objects belong to the same composition, (3) sharing of components between compositions, (4) reference from one composition to ano...

The Anatomy of Category-specific Object Naming in Neurodegenerative Diseases

Neuropsychological studies suggest that knowledge about living and nonliving objects is processed in separate brain regions. However, lesion and functional neuroimaging studies have implicated different areas. To address this issue, we used voxel-based morphometry to correlate accuracy in naming line drawings of living and nonliving objects with gray matter volumes in 152 patients with various ...
