Effects of lexical ambiguity on perception: A test of the label feedback hypothesis using a visual oddball paradigm.

Abstract

We used a visual oddball paradigm to investigate whether a shared verbal label makes two objects belonging to different conceptual categories less perceptually distinct. In Experiment 1, the critical images shared a label as well as some perceptual features referring to the color and the fruit), and in Experiment 2, the critical images shared a label but no perceptual features referring to the animal and the sports equipment). In both experiments comparison images were similar to each of the critical images but they did not share a label. A reduced deviant-related negativity (DRN) was observed for critical images compared with comparison images in both experiments, suggesting that the critical image pairs were perceived as less distinct than comparison pairs. These results extend previous research using the visual oddball paradigm that has shown that images from the same conceptual category are perceived as more distinct when they have different labels, and provide further support for the label-feedback hypothesis (Lupyan, 2012) in which language is assumed to modulate perception online.

Effects of Chinese word structure on object perception in Chinese–English bilinguals: Evidence from an ERP visual oddball paradigm

“…For each participant, the data from the 5 electrodes were averaged. This focus on parieto-occipital electrodes is consistent with recent vMMN studies which also have presented only data averaged across electrodes in this area (e.g., Athanasopoulos et al, 2010; Boutonnet et al, 2013; Jouravlev et al, 2018; Mo, Xu, Kay & Tan, 2011; Thierry et al, 2009). To ensure that ERPs reflect only the deviancy effect rather than specific perceptual characteristics of stimuli, ERPs elicited by robin and ostrich were averaged when they were presented as standards and, further, when they were presented as deviants.…”

“…In the current study, the vMMN effect appeared in the same early window (140–180 ms) and in the same scalp location (posterior) as in previous studies investigating vMMN effects (e.g., Athanasopoulos et al, 2010; Jouravlev et al, 2018). The early timing of the vMMN component is one reason that it is believed to reflect only perceptual processes (Boutonnet et al, 2013); lexical access for a newly-presented item is not likely to have occurred at this early time window.…”

Some studies have used event-related brain potentials (ERPs) and a visual-oddball paradigm (e.g., Boutonnet et al, 2013;Jouravlev et al, 2018;Thierry et al, 2009;Xia et al, 2019).…”

“…Studies have found that two stimuli that share a verbal label are perceived as more similar than stimuli that do not share a label. Evidence was found in the domains of colour perception (Athanasopoulos, 2009; Athanasopoulos, Dering, Wiggett, Kuipers & Thierry, 2010; Forder & Lupyan, 2017; Hu et al, 2014; Roberson, 2012; Roberson & Davidoff, 2000; Thierry et al, 2009; Winawer, Witthoft, Frank, Wu, Wade & Boroditsky, 2007; Xia, Xu & Mo, 2019), pitch perception (Dolscheid, Shayan, Majid & Casasanto, 2013), time and spatial perception (Boroditsky, 2001; Boroditsky, Fuhrman & McCormick, 2011; Casasanto & Boroditsky, 2008; Choi & Hattrup, 2012; Fuhrman, McCormick, Chen, Jiang, Shu, Mao & Boroditsky, 2011; Lai & Boroditsky, 2013; Y. Li et al, 2018), and object perception (Boutonnet, Athanasopoulos & Thierry, 2012; Boutonnet, Dering, Viñas-Guasch & Thierry, 2013; Jouravlev, Taikh & Jared, 2018; Masuda, Ishii, Miwa, Rashid, Lee & Mahdi, 2017).

“…More recently, Jouravlev et al (2018) used a visual-oddball paradigm to investigate the perception of objects that share a common verbal label but belong to different conceptual categories. In their Experiment 1, pictures of orange as a fruit and orange as a colour were used as critical stimuli.…”
