Two experiments are reported that explore the influence of strength of the prime-target relationship on the observed priming effects in young, healthy old, and individuals diagnosed with dementia of the Alzheimer type (DAT). In Experiment 1, participants were auditorily presented primes (FURNITURE) and after varying delays presented visual targets that were (1) high-strength related (e.g., SOFA...

The lexical representation of complex words in Indo-European languages is generally assumed to depend on semantic compositionality. This study investigated whether semantically compositional and noncompositional derivations are accessed via their constituent units or as whole words. In an overt visual priming experiment (300 ms stimulus onset asynchrony, SOA), event-related potentials (ERPs) we...

Differences in the semantic priming effect comparing child and adult performance have been found by some studies. However, these differences are not well established, mostly because of the variety of methods used by researchers around the world. One of the main issues concerns the absence of semantic priming effects on children at stimulus onset asynchrony (SOA) smaller than 300ms. The aim of t...

Introduction Semantic priming tasks provide a sensitive measure of word recognition and word meaning access. While functional MRI studies of semantic priming suggest involvement of a fronto-temporal network, regional gray matter volume associated with semantic priming in healthy older adults has not been considered. There is still some debate in the literature regarding whether semantic priming...

A number of studies have shown that skilled readers decompose morphologically complex words upon encountering them (for a review, see Rastle & Davis, 2008). It has been proposed that this segmentation process is early and automatic and is driven by orthographic form, while being blind to semantic content, thus also called morpho-orthographic (Rastle, Davis, & New, 2004; Taft, 2003). One key fin...

in this paper we classify fuzzy subgroups of the dihedral group $d_{pqrs}$  for distinct primes  $p$, $q$, $r$ and $s$. this follows similar work we have done on distinct fuzzy subgroups of some dihedral groups.we present formulae for the number of (i) distinct maximal chains of subgroups, (ii) distinct fuzzy subgroups and (iii) non-isomorphic classes of fuzzy subgroups under our chosen equival...

In this study, we looked at priming eVects produced by a short presentation (47 ms) of morphologically complex pseudowords in French. In Experiment 1, we used as primes semantically interpretable pseudowords made of the grammatical combination of a root and a suYx, such as rapidiWer “to quickify.” In Experiment 2, we used non-morphological pseudowords such as rapiduit, where -uit is an existing...

Many models of word recognition assume that processing proceeds sequentially from analysis of form to analysis of meaning. In the context of morphological processing, this implies that morphemes are processed as units of form prior to any influence of their meanings. Some interpret the apparent absence of differences in recognition latencies to targets (SNEAK) in form and semantically similar (...

It has been proposed that the loose associations characteristic of thought disorder in schizophrenia result from an abnormal increase in the automatic spread of activation through semantic memory. We tested this hypothesis by examining the time course of neural semantic priming using event-related potentials (ERPs). ERPs were recorded to target words that were directly related, indirectly relat...

The aim of the present study was to examine whether priming can occur due to recent perceptual processing of the same stimulus with minimal influence from conceptual process and also to investigate its underlying neural mechanisms using fMRI. Words were presented in mirror orientation in a word identification priming task. The presentation durations of the primes were titrated individually so t...
