Inhibitory priming in auditory word recognition: Is it really the product of response biases ?

2007

Les études en amorçage phonologique ont révélé des temps de réponse plus lents lorsque des mots cibles sont précédés d’une amorce partageant avec eux les premiers phonèmes. Cependant, l’interprétation de l’effet d’amorçage inhibiteur est source de controverses. Alors que certains auteurs ont interprété l’effet comme reflétant des processus lexicaux, Pitt et Shoaf (2002) ont émis l’hypothèse que l’effet résulterait d’une surprise des participants lorsqu’ils rencontrent le premier essai relié. Pour éviter un tel biais de réponse, nous avons inclus des amorces et des cibles reliées dans la session d’entraînement, et nous avons comparé comme l’ont fait Pitt et  Shoaf, l’amplitude de l’effet sur…

On the flexibility of letter position coding during lexical processing: the case of Thai.

2012

In Indo-European languages, letter position coding is particularly noisy in middle positions (e.g., judge and jugde look very similar), but not in the initial letter position (e.g., judge vs. ujdge). Here we focus on a language (Thai) which, potentially, may be more flexible with respect to letter position coding than Indo-European languages: (i) Thai is an alphabetic language which is written without spaces between words (i.e., there is a degree of ambiguity in relation to which word a given letter belongs to) and (ii) some of the vowels are misaligned (e.g., [Formula: see text]/ε:bn/ is pronounced as /bε:n/), whereas others are not (e.g., [Formula: see text]/a:p/ is pronounced as /a:p/).…

Further evidence that the effects of repetition on subjective time depend on repetition probability

2017

Repeated stimuli typically have shorter apparent duration than novel stimuli. Most explanations for this effect have attributed it to the repeated stimuli being more expected or predictable than the novel items, but an emerging body of work suggests that repetition and expectation exert distinct effects on time perception. The present experiment replicated a recent study in which the probability of repetition was varied between blocks of trials. As in the previous work, the repetition effect was smaller when repeats were common (and therefore more expected) than when they were rare. These results add to growing evidence that, contrary to traditional accounts, expectation increases apparent …

Priming in word stem completion tasks: comparison with previous results in word fragment completion tasks

2015

This study investigates priming in an implicit Word Stem Completion (WSC) task. A total of 305 participants performed a WSC task in two phases (study and test). The test phase included 63 unique-solution stems and 63 multiple-solution stems. After confirming the presence of priming (mean = 0.22), analysis revealed that it was stronger in the case of multiple-solution stems, indicating that the stems were not a homogeneous group of stimuli. Thus, further analyses were performed only for the data of the unique-solution stems. The correlations between priming and a set of conceptual (familiarity, frequency of use, number of meanings) and non-conceptual (letters/blanks ratio and difficulty of c…

Host-Derived CD8+ Dendritic Cells Protect Against Acute Graft-versus-Host Disease after Experimental Allogeneic Bone Marrow Transplantation

2014

Graft-versus-host disease (GVHD) is a frequent life-threatening complication after allogeneic hematopoietic stem cell transplantation (HSCT) and induced by donor-derived T cells that become activated by host antigen-presenting cells. To address the relevance of host dendritic cell (DC) populations in this disease, we used mouse strains deficient in CD11c(+) or CD8α(+) DC populations in a model of acute GVHD where bone marrow and T cells from BALB/c donors were transplanted into C57BL/6 hosts. Surprisingly, a strong increase in GVHD-related mortality was observed in the absence of CD11c(+) cells. Likewise, Batf3-deficient (Batf3(-/-)) mice that lack CD8α(+) DCs also displayed a strongly incr…

Non-conscious effect of food odors on children's food choices varies by weight status

2017

Open access original research (article number UNSP 16); OBJECTIVE: Food cues are omnipresent in the daily environment and may influence eating behavior even non-consciously. An increased reactivity to food cues, such as food odors, has been shown to be correlated with obesity in children. The objective of this study is to investigate whether the non-conscious influence of food odors on children's food choices varies by their weight status. METHODS: Seventy-four children, of whom 29 were obese, took part in this study. The children performed a food choice intention task presented as a computer game in which 30 pairs of food images (a fatty-sweet food picture vs. a fruit picture) successively…

Primed Authenticity: How Priming Impacts Authenticity Perception of Social Media Influencers

2019

Though organizations increasingly collaborate with social media influencers, such as bloggers and videobloggers, little is known as to how the contextual cues related to sponsored content affect the authenticity perception of the social media influencers among audience members. This study explores how positive and negative priming of sponsored content shapes the authenticity perception of the vlogger among its audience members. Four different manipulation conditions were constructed to study a U.S. based travel vlog on Qualtrics, with data collected via Amazon’s Mechanical Turk. A theory-guided content analysis of 211 open viewer responses was conducted to compare perceptions of authenticit…

Priming effect increases with depth in a boreal forest soil

2016

Abstract Climate warming increases labile carbon (C) inputs to soil through increased photosynthesis and C allocation belowground. This could counterintuitively lead to losses of soil C via priming effects (PE): the stimulation of soil organic matter (SOM) decomposition caused by labile C addition. Systematic quantification of PEs in different ecosystems is needed. We measured PEs of free-living soil microbes in different layers of a boreal forest soil, and found that the relative magnitude of the PE increased with soil depth. The relationship between relative PE and the added glucose amount also depended on the soil layer. Our results indicate that the decomposition of SOM in deeper soil l…
