“…The variability of meaningfulness ratings in all four experiments reliably justifies the individual rating method we used for each subject. On the basis of these methods, our behavioral studies in Experiment 1 and 2 found that conceptual priming was only evident for stimuli rated by individual subjects as meaningful, which was in line with prior studies using various stimuli, for example, squiggles (Voss and Paller, 2007 ; Voss et al, 2010b , 2012a ), obscure words (Voss et al, 2010a ), and ancient Chinese characters (Hou et al, 2013 ). On the basis of prior studies, we further found color effects on response facilitation are selective for High-M stimuli.…”

“…However, some experiments have shown that familiarity occurs even without FN400 effects (Yovel and Paller, 2004 ; Danker et al, 2008 ; Voss and Paller, 2009 ) suggesting that perhaps FN400 is not a unique indicator of familiarity. Other findings have indicated that FN400 effects could reflect conceptual processing during recognition (Olichney et al, 2000 ; Voss and Paller, 2006 , 2007 ; Voss et al, 2010a ; Voss and Federmeier, 2011 ; Hou et al, 2013 ). For instance, Voss et al ( 2010a ) used obscure words as stimuli so as to dissociate the neural correlates of familiarity and conceptual processing; the results indicated that FN400 effects were found only for the words that elicited meaningful associations, despite matched familiarity with meaningless words that did not produce FN400 effects.…”

It is difficult to pinpoint the border between perceptual and conceptual processing, despite their treatment as distinct entities in many studies of recognition memory. For instance, alteration of simple perceptual characteristics of a stimulus can radically change meaning, such as the color of bread changing from white to green. We sought to better understand the role of perceptual and conceptual processing in memory by identifying the effects of changing a basic perceptual feature (color) on behavioral and neural correlates of memory in circumstances when this change would be expected to either change the meaning of a stimulus or to have no effect on meaning (i.e., to influence conceptual processing or not). Abstract visual shapes (“squiggles”) were colorized during study and presented during test in either the same color or a different color. Those squiggles that subjects found to resemble meaningful objects supported behavioral measures of conceptual priming, whereas meaningless squiggles did not. Further, changing color from study to test had a selective effect on behavioral correlates of priming for meaningful squiggles, indicating that color change altered conceptual processing. During a recognition memory test, color change altered event-related brain potential (ERP) correlates of memory for meaningful squiggles but not for meaningless squiggles. Specifically, color change reduced the amplitude of frontally distributed N400 potentials (FN400), implying that these potentials indicated conceptual processing during recognition memory that was sensitive to color change. In contrast, color change had no effect on FN400 correlates of recognition for meaningless squiggles, which were overall smaller in amplitude than for meaningful squiggles (further indicating that these potentials signal conceptual processing during recognition). Thus, merely changing the color of abstract visual shapes can alter their meaning, changing behavioral and neural correlates of memory. These findings are relevant to understanding similarities and distinctions between perceptual and conceptual processing as well as the functional interpretation of neural correlates of recognition memory.

“…LPC enhancement has also been reported for familiar compared to unfamiliar stimuli [63]. As the relative familiarity of brand products and no name products differed, an alternative explanation of the greater LPC could be that this simply reflects different degrees of familiarity rather than differential emotional engagement.…”

An ERP-study of brand and no-name products

BackgroundBrands create product personalities that are thought to affect consumer decisions. Here we assessed, using the Go/No-go Association Task (GNAT) from social psychology, whether brands as opposed to no-name products are associated with implicit positive attitudes. Healthy young German participants viewed series of photos of cosmetics and food items (half of them brands) intermixed with positive and negative words. In any given run, one category of goods (e.g., cosmetics) and one kind of words (e.g., positive) had to be responded to, whereas responses had to be withheld for the other categories. Event-related brain potentials were recorded during the task.ResultsUnexpectedly, there were no response-time differences between congruent (brand and positive words) and incongruent (brand and negative words) pairings but ERPs showed differences as a function of congruency in the 600–750 ms time-window hinting at the existence of implicit attitudes towards brand and no-name stimuli. This finding deserves further investigation in future studies. Moreover, the amplitude of the late positive component (LPC) was found to be enhanced for brand as opposed to no-name stimuli.ConclusionsCongruency effects suggest that ERPs are sensitive to implicit attitudes. Moreover, the results for the LPC imply that pictures of brand products are more arousing than those of no-name products, which may ultimately contribute to consumer decisions.

“…Accordingly, two time windows, 300-550 ms and 550-800 ms, were used to capture the frontal and parietal intact/new effects, respectively. Mean amplitudes for statistical analyses in these windows were obtained from frontal (collapsed across F3, Fz, and F4), the central (collapsed across C3, Cz, and C4) and the parietal (collapsed across P3, Pz, and P4) scalp locations (Han et al, 2018;Hou et al, 2013;Molinaro et al, 2011).…”

Some aspects of our memory are enhanced by emotion, whereas other can be unaffected or even hinder. In particular, previous studies report impaired associative memory of emotional content, an effect termed associative "emotion interference". The current study utilized EEG and an associative recognition paradigm to investigate the cognitive and neural mechanisms associated with this effect. In two experiments, participants studied negative and neutral stimulus-pairs that were either semantically related or unrelated. In Experiment 1 emotions were relevant to the encoding task (valance judgment) whereas in Experiment 2 emotions were irrelevant (familiarity judgment). In a subsequent associative recognition test, EEG was recorded while participants discriminated between intact, rearranged, and new pairs. An associative emotional interference effect was observed in both experiments, but was attenuated for semantically related pairs when emotions were relevant to the study task. Moreover, a modulation of an early associative memory ERP component depended on task relevancy of emotions, and occurred for negative pairs when emotions were relevant, but for semantically related pairs when emotions were irrelevant. A later ERP component depicted a more general pattern, and was observed in all experimental conditions. These results suggest that both emotions and semantic relations can act as organizing principles that promote associative binding. Their ability to contribute to successful retrieval depends on specific task demands.
