Four lexical decision experiments were conducted to examine under which conditions automatic semantic priming effects can be obtained. Experiments 1 and 2 analyzed associative/semantic effects at several very short stimulus-onset asynchronies (SOAs), whereas Experiments 3 and 4 used a single-presentation paradigm at two response-stimulus intervals (RSIs).(More)
A number of experiments have shown that the magnitude of the associative priming effect increases substantially when there is a high proportion of associatively related pairs in the list when the stimulus-onset asynchrony (SOA) between prime and target is long (more than 400 ms). In the present series of experiments we manipulated the proportion of(More)
Four experiments were designed to investigate whether the frequency of words used to create pseudowords plays an important role in lexical decision. Computational models of the lexical decision task (e.g., the dual route cascaded model and the multiple read-out model) predict that latencies to low-frequency pseudowords should be faster than latencies to(More)
To analyze the impact of outline shape on visual word recognition, the visual pattern of the stimuli can be distorted by size alternation. Contrary to the predictions of models that rely on outline shape (Allen, Wallace, & Weber, 1995), the effect of size alternation was greater for low-frequency words than for high-frequency words in a lexical decision(More)
In the go/no-go lexical decision task (LDT), participants are instructed to respond as quickly as they can when a word is presented and not to respond if a nonword is presented. By minimizing part of the response selection process in the experimental task, the impact of response decision time on the obtained lexical decision time is probably reduced(More)
We present two experiments in which we measured lexical decision latencies and errors to words with few or many orthographic neighbors (ie., Coltheart's N). The main goal of the study was to examine whether or not the neighborhood size effect in a lexical decision task could be affected by the exposure duration of the stimulus item (unlimited vs. limited(More)
This paper reviews recent research on the effects of " orthographic neighbors " (i.e., words that can be created by changing one letter of the stimulus item, preserving letter positions, see Coltheart et al., 1977) on reading and laboratory word identification tasks. We begin this paper with a literature review on the two basic " neighborhood " effects(More)
decisión léxica sí-no, lo que da lugar a que los TRs sean (general-mente) menores que los obtenidos con la tarea de decisión léxica sí-no (Perea, Rosa y Gómez, 2002). (Pensemos que en la tarea sí-no, el participante debe recordar cuál es la tecla correspondiente a «palabra» y cuál es la correspondiente a «no-palabra».) Es impor-tante indicar que la tarea de(More)
Do all visual features in a word's constituent letters have the same importance during lexical access? Here we examined whether some components of a word's letters (midsegments, junctions, terminals) are more important than others. To that end, we conducted two lexical decision experiments using a delayed segment technique with lowercase stimuli. In this(More)
