Transposed-letter effects: Consonants, vowels and letter frequency
2008
There is now considerable evidence (e.g., Perea & Lupker, 2003a, 2003b) that transposed-letter nonword primes (e.g., jugde for JUDGE) are more effective primes than replacement-letter nonword primes (e.g., jupte for JUDGE). Recently, Perea and Lupker (2004) demonstrated that, in Spanish, this transposed-letter prime advantage exists only when the transposed letters are consonants (C-C transpositions) and not when they are vowels (V-V transpositions). This vowel-consonant difference causes problems even for models that can successfully explain transposed-letter effects (e.g., SOLAR, Davis, 1999). In Experiment 1 in the present paper, we demonstrated a parallel result in a language with a dif…
Are root letters compulsory for lexical access in Semitic languages? The case of masked form-priming in Arabic.
2014
Do Semitic and Indo-European languages differ at a qualitative level? Recently, it has been claimed that lexical space in Semitic languages (e.g., Hebrew, Arabic) is mainly determined by morphological constraints, while lexical space in Indo-European languages is mainly determined by orthographic constraints (Frost, Kugler, Deutsch, & Forster, 2005). One of the key findings supporting the qualitative difference between Semitic and Indo-European languages is the absence of masked form priming in Hebrew/Arabic with productive words. Here we examined whether masked form priming occurs in Arabic words when one of the letters from the productive root is replaced in the prime stimulus by another …
Neighbourhood distribution interacts with orthographic priming in the lexical decision task
2004
Lexical decision tasks (LDTs) were used with a masked priming procedure to test whether neighbourhood distribution interacts with orthographic priming. Word targets had either ‘single’ neighbours when their two higher frequency orthographic neighbours were spread over letter positions (e.g., neighbours of LOBE: robe-loge) or ‘twin’ neighbours when they were concentrated on a single letter position (e.g., neighbours of FARD: lard-tard). All word targets were preceded by their highest frequency orthographic neighbour or by a control prime. An inhibitory priming effect was found for words with single neighbours, but not for words with twin neighbours, in both a yes/no LDT (Experiment 1a) and a…
I saw this somewhere else: the Spanish Ambiguous Words (SAW) database
2017
The present paper describes the Spanish Ambiguous Words (SAW) database, which comprises 210 words (133 polysemous and 77 homographs). Three-hundred and fifteen Spanish university students took part in the study on which SAW is based. First, subjective word meanings and senses were collected by means of a meaning retrieval task. Two judges then assigned participants’ responses to different categories of meaning according to lexicographical and statistical criteria. Results showed that, while there was a relatively high relationship between the number of senses included in the dictionary and those provided by participants (r = .62), regression analyses on lexical decision and naming times rev…
Transposed-letter and laterality effects in lexical decision.
2006
Two divided visual field lexical decision experiments were conducted to examine the role of the cerebral hemispheres in transposed-letter similarity effects. In Experiment 1, we created two types of nonwords: nonadjacent transposed-letter nonwords (TRADEGIA; the base word was TRAGEDIA, the Spanish for TRAGEDY) and two-letter different nonwords (orthographic controls: TRATEPIA). In Experiment 2, the controls were one-letter different nonwords (TRAGEPIA) instead of two-letter different nonwords (TRATEPIA). The effect of transposed-letter similarity was substantially greater in the right visual field (left hemisphere) than in the left visual field. Furthermore, nonwords created by transposing …
The role of letters and syllables in typical and dysfluent reading in a transparent orthography
2012
The role of letters and syllables in typical and dysfluent 2nd grade reading in Finnish, a transparent orthography, was assessed by lexical decision and naming tasks. Typical readers did not show reliable word length effects in lexical decision, suggesting establishment of parallel letter processing. However, there were small effects of word syllable structure in both tasks suggesting the presence of some sublexical processing also. Dysfluent readers showed large word length effects in both tasks indicating decoding at the letterphoneme level. When lexical access was required in a lexical decision task, dyslexics additionally chunked the letters into syllables. Response duration measure rev…
“It is alive!” Evidence for animacy effects in semantic categorization and lexical decision
2019
AbstractAnimacy is one of the basic semantic features of word meaning and influences perceptual and episodic memory processes. However, evidence that this variable also influences lexicosemantic processing is mixed. As animacy is a semantic variable thought to have evolutionary roots, we first examined its influence in a semantic categorization task that did not make the animacy dimension salient, namely, concrete-abstract categorization. Animates were categorized faster (and more accurately) than inanimates. We then assessed the influence of animacy in two lexical decision experiments. In Experiment 2, we mostly used legal nonwords, whereas in Experiment 3, we varied the context of the non…
Is perception a two-way street ?The case of feedback consistency in visual word recognition
1998
It is generally assumed that during reading, the activation produced over orthographic units feeds forward to phonological units. Supporting interactive models of word recognition, Stone, Vanhoy, and Van Orden (1997) recently claimed that phonological activation reverberates to orthographic processing units and consequently constrains orthographic encoding. They found that the consistency of the relations between phonology and orthography (feedback consistency) influenced lexical decision performance. We explored the effect in five experiments conducted with French words. Although feedback consistency affected writing performance, no significant effect was observed in lexical decision even …
Are syllables phonological units in visual word recognition?
2004
A number of studies have shown that syllables play an important role in visual word recognition in Spanish. We report three lexical decision experiments with a masked priming technique that examined whether syllabic effects are phonological or orthographic in nature. In all cases, primes were nonwords. In Experiment 1, latencies to CV words were faster when primes and targets shared the first syllable (ju.nas-JU.NIO) than when they shared the initial letters but not the first syllable (jun.tu-JU.NIO). In Experiment 2, this syllabic overlap could be phonological+orthographical (vi.rel-VI.RUS) or just phonological (bi.rel-VI.RUS). A syllable priming effect was found for CV words in both the…
Are There Lower Repetition Priming Effects in Children with Developmental Dyslexia? Priming Effects in Spanish with the Masked Lexical Decision Task.
2016
The aim of this study was to compare the reaction times and errors of Spanish children with developmental dyslexia to the reaction times and errors of readers without dyslexia on a masked lexical decision task with identity or repetition priming. A priming paradigm was used to study the role of the lexical deficit in dyslexic children, manipulating the frequency and length of the words, with a short Stimulus Onset Asynchrony (SOA = 150 ms) and degraded stimuli. The sample consisted of 80 participants from 9 to 14 years old, divided equally into a group with a developmental dyslexia diagnosis and a control group without dyslexia. Results show that identity priming is higher in control childr…
