The latencies of LPP vary across studies but tend to be predominant between 400 and 800 ms (Codispoti et al., 2012). LPP has a widespread scalp distribution from the frontal to the parietal sites with maxima over central-parietal sites. LPP is sensitive to motivationally relevant stimuli, and thought to reflect overt, post-perceptive deliberative processing related to stimulus significance (Olofsson et al., 2008). Emotionally significant stimuli (e.g., pleasant and unpleasant stimuli) has been found to trigger augmented LPP relative to neutral stimuli, suggesting enhanced activation of motivational system in the brain, increased resource allocation and sustained attentive processing for motivationally relevant stimuli (Schupp et al., 2004; Ferrari et al., 2011; Leite et al., 2012). Neuromarketing studies have revealed similar findings. Pozharliev et al. (2015), for instance, asked the participants to passively view pictures of luxury and basic branded products and noted increased LPP amplitude for luxury goods in the social context. Moreover, Goto et al. (2017) designed a virtual shopping task which revealed a positive relationship between LPP amplitude and subjective preferences of products. Consequently, LPP could reflect preferences based on more elaborative and conscious cognitive processes (Goto et al., 2017).","tracks":[{"project":"TEST0","denotations":[{"id":"29731705-153-161-826804","span":{"begin":153,"end":157},"obj":"[\"10731776\"]"},{"id":"29731705-110-118-826805","span":{"begin":270,"end":274},"obj":"[\"22092301\"]"},{"id":"29731705-174-182-826806","span":{"begin":571,"end":575},"obj":"[\"18164800\"]"},{"id":"29731705-227-235-826807","span":{"begin":926,"end":930},"obj":"[\"20701711\"]"},{"id":"29731705-227-235-826808","span":{"begin":946,"end":950},"obj":"[\"22226675\"]"},{"id":"29731705-23-31-826809","span":{"begin":1232,"end":1236},"obj":"[\"28666891\"]"},{"id":"29731705-118-126-826810","span":{"begin":1490,"end":1494},"obj":"[\"28666891\"]"}],"attributes":[{"subj":"29731705-153-161-826804","pred":"source","obj":"TEST0"},{"subj":"29731705-110-118-826805","pred":"source","obj":"TEST0"},{"subj":"29731705-174-182-826806","pred":"source","obj":"TEST0"},{"subj":"29731705-227-235-826807","pred":"source","obj":"TEST0"},{"subj":"29731705-227-235-826808","pred":"source","obj":"TEST0"},{"subj":"29731705-23-31-826809","pred":"source","obj":"TEST0"},{"subj":"29731705-118-126-826810","pred":"source","obj":"TEST0"}]},{"project":"0_colil","denotations":[{"id":"29731705-10731776-826804","span":{"begin":153,"end":157},"obj":"10731776"},{"id":"29731705-22092301-826805","span":{"begin":270,"end":274},"obj":"22092301"},{"id":"29731705-18164800-826806","span":{"begin":571,"end":575},"obj":"18164800"},{"id":"29731705-20701711-826807","span":{"begin":926,"end":930},"obj":"20701711"},{"id":"29731705-22226675-826808","span":{"begin":946,"end":950},"obj":"22226675"},{"id":"29731705-28666891-826809","span":{"begin":1232,"end":1236},"obj":"28666891"},{"id":"29731705-28666891-826810","span":{"begin":1490,"end":1494},"obj":"28666891"}],"attributes":[{"subj":"29731705-10731776-826804","pred":"source","obj":"0_colil"},{"subj":"29731705-22092301-826805","pred":"source","obj":"0_colil"},{"subj":"29731705-18164800-826806","pred":"source","obj":"0_colil"},{"subj":"29731705-20701711-826807","pred":"source","obj":"0_colil"},{"subj":"29731705-22226675-826808","pred":"source","obj":"0_colil"},{"subj":"29731705-28666891-826809","pred":"source","obj":"0_colil"},{"subj":"29731705-28666891-826810","pred":"source","obj":"0_colil"}]},{"project":"2_test","denotations":[{"id":"29731705-10731776-38674698","span":{"begin":153,"end":157},"obj":"10731776"},{"id":"29731705-22092301-38674699","span":{"begin":270,"end":274},"obj":"22092301"},{"id":"29731705-18164800-38674700","span":{"begin":571,"end":575},"obj":"18164800"},{"id":"29731705-20701711-38674701","span":{"begin":926,"end":930},"obj":"20701711"},{"id":"29731705-22226675-38674702","span":{"begin":946,"end":950},"obj":"22226675"},{"id":"29731705-28666891-38674703","span":{"begin":1232,"end":1236},"obj":"28666891"},{"id":"29731705-28666891-38674704","span":{"begin":1490,"end":1494},"obj":"28666891"}],"attributes":[{"subj":"29731705-10731776-38674698","pred":"source","obj":"2_test"},{"subj":"29731705-22092301-38674699","pred":"source","obj":"2_test"},{"subj":"29731705-18164800-38674700","pred":"source","obj":"2_test"},{"subj":"29731705-20701711-38674701","pred":"source","obj":"2_test"},{"subj":"29731705-22226675-38674702","pred":"source","obj":"2_test"},{"subj":"29731705-28666891-38674703","pred":"source","obj":"2_test"},{"subj":"29731705-28666891-38674704","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"TEST0","color":"#ec93de","default":true},{"id":"0_colil","color":"#93ece0"},{"id":"2_test","color":"#ecc693"}]}]}}
