Sensory-memory-based change detection in face stimuli

Abstract

Detection of a change in face is a socially important skill. Both event-related potential (ERP) and magnetoencephalographic (MEG) measurements were conducted using face stimuli presented in an oddball paradigm to investigate detection of a change in face identity and facial expression. In condition 1, a nontarget deviant neutral face was presented among standard happy faces. In condition 2, the same deviant neutral face was presented with a standard neutral face of another person. The task in both conditions was silent counting of a second deviant (face with glasses). Non-target deviants elicited more negative ERP and corresponding MEG responses than standards in both conditions. This negativity was strongest at lateral posterior channels around 280 ms. Responses to the same deviant neutral face differed in two conditions. Deviance-related negativity resembled auditory mismatch negativity (MMN). Different responses to the same deviant in the two conditions suggest the existence of a sensory-memory trace for the standard to which the deviant was compared. 286Translational Neuroscience

Inducing Shifts in Attentional and Preattentive Visual Processing Through Brief Training on Novel Grammatical Morphemes: An Event‐Related Potential Study

“…For the analysis on the P300 elicited by “#” detection, data were filtered offline with the same 0.1–30‐Hz band‐pass filter. For the vMMN analysis, a default basic FIR filter with 1–30‐Hz band‐pass frequency was used, following previous studies focusing on vMMN in healthy adults (e.g., Beck et al., 2021; Flynn et al., 2017; Kimura, 2018; Kimura & Takeda, 2019; Susac et al., 2004; 2010). The high‐pass cutoff frequency of 1 Hz was chosen on the basis of previous recommendations (Duncan et al., 2009) and to attenuate potential superimposition of the P300 caused by the central fixation marker, which may distort the vMMN waveform (Kimura, 2018).…”

From pre-attentive processes to durable representation: An ERP index of visual distraction

“…The existence of vMMN, a scalp-elicited posterior bilateral negativity in response to visual deviance, has remained, until recently, a controversial topic (Näätänen, 1990(Näätänen, , 1991Cammann, 1990;Czigler, 1990;Pazo-Alvarez et al, 2003;Heslenfeld, 2003). However, throughout the past decade and into the current, a multitude of independent replications of the vMMN have placed vMMN upon a firm empirical footing (Astikainen and Hietanen, 2009;Astikainen et al, 2004Astikainen et al, , 2008Berti, 2011;Clifford et al, 2010;Czigler, 2007;Czigler et al, 2004Czigler et al, , 2007Czigler and Pato, 2009;Czigler and Sulykos, 2010;Fisher et al, 2010;Flynn et al, 2009;Kimura et al, 2010a,c,d;Liu and Shi, 2008;Lyyra et al, 2012;Maekawa et al, 2009;Mao et al, 2004;Stefanics et al, 2011Shtyrov et al, 2013;Sulykos and Czigler, 2011;Sušac et al, 2004Sušac et al, , 2010aSušac et al, ,b, 2011 for reviews, please see Kimura et al, 2011;Kimura, 2012;Winkler and Czigler, 2012). The vMMN is believed to be an analog of the more well-studied auditory MMN (Näätänen et al, 1978;Tiitinen et al, 1994), elicited at similar latencies and largely pre-attentively as well (Näätänen et al; for a complementary perspective, see Erlbeck et al, 2015;Campbell, 2015).…”
