Eye movements when reading words with $YMβOL$ and NUM83R5: There is a cost

2009

Recent evidence from masked priming experiments has revealed that readers regularize letter-like symbols and letter-like numbers into their corresponding base letters with minimal processing cost. However, one open question is whether the same pattern occurs when these items are presented during normal silent reading. In the present study, we respond to this question in an eye-movement experiment that included sentences with words that had symbols and numbers as letters, as in “YESTERDAY I SAW THE SECRE74RY WORKING VERY HARD”. Results revealed that there is a greater reading cost associated with letter-by-number replacements than with letter-by-symbol replacements, especially when the repla…

Unveiling the boost in the sandwich priming technique.

2021

The masked priming technique (which compares #####-house-HOUSE vs. #####-fight-HOUSE) is the gold-standard tool to examine the initial moments of word processing. Lupker and Davis showed that adding a pre-prime identical to the target produced greater priming effects in the sandwich technique (which compares #####-HOUSE-house-HOUSE vs #####-HOUSE-fight-HOUSE). While there is consensus that the sandwich technique magnifies the size of priming effects relative to the standard procedure, the mechanisms underlying this boost are not well understood (i.e., does it reflect quantitative or qualitative changes?). To fully characterise the sandwich technique, we compared the sandwich and standard t…

Masked priming effects are modulated by expertise in the script.

2010

In a recent study using a masked priming same–different matching task, García-Orza, Perea, and Muñoz (2010) found a transposition priming effect for letter strings, digit strings, and symbol strings, but not for strings of pseudoletters (i.e., [Formula: see text] produced similar response times to the control pair [Formula: see text]). They argued that the mechanism responsible for position coding in masked priming is not operative with those “objects” whose identity cannot be attained rapidly. To assess this hypothesis, Experiment 1 examined masked priming effects in Arabic for native speakers of Arabic, whereas participants in Experiments 2 and 3 were lower intermediate learners of Arabi…

Are transposition effects specific to letters?

2010

Recent research has consistently shown that pseudowords created by transposing two letters are perceptually similar to their corresponding base words (e.g., jugde–judge). In the framework of the overlap model (Gomez, Ratcliff, & Perea, 2008), this effect is due to a noisy process in the localization of the “objects” (e.g., letters, kana syllables). In the present study, we examine whether this effect is specific to letter strings or whether it also occurs with other “objects” (namely, digits, symbols, and pseudoletters). To that end, we conducted a series of five masked priming experiments using the same–different task. Results showed robust effects of transposition for all objects, ex…

The effect of harmonic context on phoneme monitoring in vocal music

2001

The processing of a target chord depends on the previous musical context in which it has appeared. This harmonic priming effect occurs for fine syntactic-like changes in context and is observed irrespective of the extent of participants' musical expertise (Bigand & Pineau, Perception and Psychophysics, 59 (1997) 1098). The present study investigates how the harmonic context influences the processing of phonemes in vocal music. Eight-chord sequences were presented to participants. The four notes of each chord were played with synthetic phonemes and participants were required to quickly decide whether the last chord (the target) was sung on a syllable containing the phoneme /i/ or /u/. The mu…

Where is the syllable priming effect in visual word recognition?

2003

Recent studies using the masked priming paradigm have reported facilitating effects of syllable primes in French and English word naming (Ferrand, Segui, & Grainger, 1996; Ferrand, Segui, & Humphreys, 1997). However, other studies have not been able to replicate these effects in Dutch and English (Schiller, 1998, 1999, 2000). In Experiment 1, using the same stimuli and procedure as Ferrand et al. (1996), we did not replicate the syllable priming effect in French. In Experiments 2a and 2b, when prime duration was increased (from 30 to 45 and 60 ms), we did not obtain a syllable priming effect. In Experiment 3, with 60 participants and exactly the same procedure as Ferrand et al. (1996), we a…

Evolutionary ecology of immune priming in the mealworm beetle, Tenebrio molitor

2017

Many organisms can improve their immune response as a function of their immunological experience, a phenomenon called immune priming. While the mechanisms through which immune priming is achieved remain unknown, individuals that survived to a given parasite are better protected against subsequent exposures. This immune priming can cross generations (trans-generational immune priming – TGIP), preparing offspring for prevailing parasite environment. Both individual and trans-generational immune priming might be adaptive and may have evolved from repeated challenges by the same pathogens during the host lifetime or across generation. While protection could be cross-reactive, a certain level of…

Impact of a non-consciously perceived odour on subsequent food choices

2013

Poster (1 page) ; http://www.pangborn2013.com/; International audience; Although people were initially considered as entirely conscious of the motivations driving their behaviour and choices, current research in psychology suggests that a significant part of choices and decision-making is influenced by unconscious processes (Bargh, & Chartrand, 1999; Dijksterhuis et al., 2005). To study the unconscious processes involved in food choice, we used the priming paradigm. In a first experiment, we showed that non-consciously perceived fruity odours impacted intentions of food choices (on a menu card), guiding participants toward more fruit and/or vegetable (Gaillet et al., under review). The pres…

Conscious and nonconscious influences in the sensory domain

2013

Présentation (résumé 1 p.) ; http://www.pangborn2013.com/; International audience; Characterizing the relationships between conscious and unconscious processing is one of the most important goals of cognitive psychology. Renewed interest in the nature of consciousness has reignited long-standing debates about the reach of the unconscious -- the extent to which behaviour can be influenced by knowledge we are not aware of. According to Nisbett & Wilson (1977), subjects can be "(a) unaware of the existence of a stimulus that importantly influenced a response, (b) unaware of the existence of the response, and (c) unaware that the stimulus has affected the response." Many studies have now (argua…
