Previous word recognition studies have shown that the pupillary response is sensitive to a word’s frequency. However, such a pupillary effect may be due to the process of executing a response, instead of being an index of word processing. With the aim of exploring this possibility, we recorded the pupillary responses in two experiments involving a...

In the present study we examined electrophysiological and behavioral correlates of ambiguous word processing. In a lexical decision task, participants were presented with ambiguous words with unrelated meanings (i.e., homonyms; e.g., bat), ambiguous words with related meanings (i.e., polysemes; e.g., newspaper), and unambiguous words (e.g., guitar)...

It is not clear whether multiple unrelated meanings inhibit or facilitate word recognition. Some studies have found a disadvantage for words having multiple meanings with respect to unambiguous words in lexical decision tasks (LDT), whereas several others have shown a facilitation for such words. In the present study, we argue that these inconsiste...
Article
There is substantial evidence that affectively charged words (e.g., party or gun) are processed differently from neutral words (e.g., pen), although there are also inconsistent findings in the field. Some lexical or semantic variables might explain such inconsistencies, due to the possible modulation of affective word processing by these variables....

La investigación con potenciales evocados...
Article
Evaluative markers of diminution and augmentation typically express quantity or intensity. Prior evidence suggests that they also convey emotions, although it remains unexplored as to whether this function is mediated by their role in expressing quantification/intensification. Here we investigated the effects of evaluative suffixes on the assessmen...

Paranormal, pseudoscientific and conspiracy beliefs are three types of epistemically unwarranted beliefs (EUB; Lobato et al., 2014). The study of EUB is relevant, for instance, due to the adverse effects associated to believing in these type of claims (Fasce, 2018; Irwin, 2009; Jolley et al., 2020). Despite this importance, validated scales for ass...

Many studies have found that the emotional content of words affects visual word recognition. However, most of them have only considered affective valence, finding inconsistencies regarding the direction of the effects, especially in unpleasant words. Recent studies suggest that arousal might explain why not all unpleasant words elicit the same beha...

Abstract: Idioms (e.g. kick the bucket) are part of a broad spectrum of multi-word expressions (MWEs) whose representation is stored in semantic memory. Although there is a growing interest in idioms from different disciplines, there is still a lack of knowledge about how idioms are processed and represented in the mental lexicon. One of the aspect...

The study of iconicity, or the resemblance between word forms and their meanings, has been the focus of increasing attention in recent years. Nevertheless, there is a lack of large-scale normative studies on the iconic properties of words, which could prove crucial to expanding our understanding of form–meaning associations. In this work, we report...

In this study, we implemented a visual illusions contest as an educational activity within the practical programme of the subject Perception and Attention (Bachelor’s Degree in Psychology). The contest was evaluated by verifying its effectiveness as a teaching tool for achieving the competences assigned to the course. We designed questionnaires for...
Article
Semantically ambiguous and emotional words occur frequently in language, and the different meanings of ambiguous words can sometimes have different emotional loads. For example, the Spanish word heroína (heroin/heroine) can refer to a drug or to a woman who performs a heroic act. Because both ambiguity and emotionality affect word processing, there...

Ambiguous words are usually recognized faster than unambiguous words in LDT. The reason seems to be that the multiple meanings of ambiguous words engage a lot of semantic activation during word processing. However, it is not clear how this enhanced semantic activation would facilitate recognition. In addition, several studies suggest that the ambig...

PDP models of word recognition assume that ambiguous words are represented with a one-to-many mapping between orthography and semantics. Accordingly, this inconsistent mapping would lead to a slower and less accurate semantic coding for these words with respect to unambiguous words. Taking this into account, PDP models predict a disadvantage for am...

The cognate facilitation effect (i.e., a processing advantage for cognates compared to non-cognates) is an evidence of language non-selectivity in bilingual lexical access. Several studies using behavioral or electrophysiological measures have demonstrated that this effect is modulated by the degree of formal overlap between translations. However,...

In the present study we obtained behavioral and ERP differences between ambiguous and unambiguous words. Ambiguous words were recognized faster and more accurately than unambiguous word, and they showed a larger N400 amplitude than unambiguous words. On the contrary, no differences were found between polysemes and homonyms. These results support th...

A consistent finding in past research about ambiguity was that ambiguous words are recognized faster than unambiguous words. However, Rodd et al. (2002) observed an ambiguity advantage for polysemous words (ambiguous words with related meanings), but not for homonymous words (ambiguous words with unrelated meanings). Thus, Rodd et al. concluded tha...
