The Soundtrack of a Generation: a Systematic Literature Review on the Influence of Ambient Music on Generation Z Consumers

This study aims to systematically examine the role of emotional storytelling in product promotional videos and its influence on consumers' purchase intention, with a particular emphasis on skincare service products. Emotional storytelling has emerged as a persuasive marketing strategy that leverages affective narratives to foster consumer-brand relationships, build trust, and enhance behavioral responses. Given the increasing prevalence of emotionally driven promotional content across digital platforms, especially within the visually rich skincare industry, this research conducts a structured literature review to synthesize theoretical perspectives and empirical findings. Utilizing a descriptive quantitative approach, this study reviewed 30 peer-reviewed articles published between 2000 and 2024, focusing on emotional narrative structures, psychological mechanisms, and behavioral outcomes. The findings indicate that emotional storytelling positively impacts consumer purchase intention by fostering narrative transportation, emotional contagion, and perceived authenticity. Specifically, narrative coherence, emotional valence, and brand relatability were identified as key drivers of consumer engagement. In the skincare sector, emotionally charged videos that depict transformation, self-care, and identity alignment proved to be especially effective in motivating purchasing behavior. Moreover, platform-specific dynamics such as video format and interactivity were found to moderate storytelling effectiveness. The study contributes to the theoretical development of affective marketing and offers practical guidance for brands aiming to craft emotionally resonant promotional content. It also proposes a conceptual framework for future empirical testing on emotional storytelling and consumer behavior in the context of beauty and self-care services.

The advancement of technological development in the digital business world proliferates from time to time. The use of Internet networks for daily needs is increasing rapidly, especially for buying and selling transactions. Therefore, live shopping technology has emerged as a new shopping trend nowadays. This study used qualitative methodology by doing a literature review of 20 relevant international journals published between 2019 and 2023. The database used for this systematic literature review is Scopus. This study aims to define live-streaming shopping and purchase intention and find its influence on purchase intention from prior studies. This study aims to systematically review factors influencing consumers’ purchase intention in live-streaming shopping. The findings indicate that live-streaming shopping significantly impacts viewers’ purchase intention through various factors, including interactivity between viewers and streamers, engagement, trust, price, promotion strategies, influencers, and Key Opinion Leaders (KOL). Furthermore, the study reveals that most prior research in this area applied a quantitative approach using PLS-SEM or CB-SEM. However, existing literature suggests that future research should incorporate mixed-methodology to gain a more comprehensive understanding. This study contributes by highlighting the correlation between live-streaming shopping and purchase intention, as well as the dominant research methodologies used in previous studies. The findings provide valuable insights for businesses and researchers in understanding consumer behavior in live-streaming shopping environments.

Collaborative consumption (CC) is becoming a key concept in marketing. Despite the topic’s relevance, the academic literature on consumer behavior in collaborative consumption remains very fragmented. This present research aims to provide a systematic review of consumer behavior in collaborative consumption research in the existing literature. An extensive literature review was systematically conducted on collaborative consumption spread over the time period between 2010 to 2021 published journals which were identified from online academic and research databases of Web of science and EBSCO. A total of 97 conceptual and empirical articles were analyzed based on criteria such as year of publication, theoretical underpinning, methodological approaches, etc. The paper highlights the critical emergent themes and sub-themes, extensively used methodologies and analysis approaches, and dominant theoretical underpinnings. By providing the distribution schema of collaborative consumption articles based on the mentioned criteria and the future research areas, the present study will help future researchers understand the current status of collaborative consumption research in the marketing and consumer behavior discipline and take this research area forward. Our theme-based segregation of collaborative consumption gives a deeper insight to the managers of sharing services concerning the key motivations and constraints of collaborative consumption. This systematic literature review provides a holistic view of consumer behavior in collaborative consumption. It highlights three major research themes (customer-centric studies, sustainability-centric studies, and consumer trust studies) and their related and relevant sub-themes to date addressed in the research studies.

Emotion reactivity refers to the intensity of changes in positive and negative emotion following a stimulus, typically studied with respect to daily stressors (e.g., arguments, demands) or laboratory stressors, including the Trier Social Stress Test (TSST). Yet, it is unclear whether emotion reactivity to daily and to laboratory stressors are related. The present study examined whether greater emotion reactivity to daily stressors (i.e., arguments, demands) is associated with greater reactivity to the TSST. Late adolescents (N = 82; Mage = 18.35, SD = 0.51, range 17–19; 56.1% female; 65.9% Latine, 34.2% European American) reported whether they experienced arguments and demands with friends, family, and individuals at school and their negative and positive emotion nightly for 15 days. They also completed the TSST, a validated paradigm for eliciting social-evaluative threat, and reported their emotion at baseline and immediately post-TSST. Multilevel models examined whether daily and laboratory emotion reactivity were related by testing whether the daily associations between arguments and demands with emotion differed by emotion reactivity to the TSST. Individuals with greater positive emotion reactivity (i.e., greater reductions in positive emotion) and greater negative emotion reactivity to the TSST showed greater positive emotion reactivity to daily demands. Emotion reactivity to the TSST was not significantly related to emotion reactivity to arguments. Findings provide preliminary evidence that emotion reactivity to the TSST relates to some aspects of daily emotion reactivity, with relations differing depending on type of daily stressor and valence of emotion. Results contextualise the implications of emotion reactivity to the TSST for daily stress processes.

The momentary processes that contribute to alcohol misuse among those with posttraumatic stress disorder (PTSD) are not well understood. Emotional responding (i.e., the intensity of an emotional response to a trauma-related stimulus) and emotion regulation (i.e., the ability to influence one's emotions), are two such crucial processes that may be important, in-the-moment determinants of drinking. This study investigated (a) associations among PTSD, emotional responding, and alcohol urge following exposure to a trauma cue, and (b) the conditional influence of emotion regulation abilities on these relationships. During an initial assessment session, 305 college students recruited from the community were classified based on Diagnostic and Statistical Manual of Mental Disorders Criterion A trauma exposure and PTSD symptom level: no trauma (NT), trauma exposure but no PTSD diagnosis (trauma only), or trauma exposure and PTSD (PTSD). During an experimental session, participants were presented with a personalized trauma cue. Emotional valence and arousal and urge to drink alcohol were reported before and after cue presentations. Emotional responding was indexed as postcue affective valence and arousal controlled for their respective baseline scores. Emotional responding to a trauma cue significantly mediated the relationship between any trauma exposure and urge to drink alcohol. Emotion regulation did not moderate this mediated pathway. Emotional responding increases momentary desires to use alcohol and may contribute to problematic drinking in those with trauma exposure. Findings may have important implications for intervention, as targeting emotional responding to trauma stimuli may help reduce alcohol risk. Future directions and limitations of the current work are discussed. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Shopping in the traditional retail environment is increasingly being influenced by technologies enabling human-computer interaction. Scientists, as well as retailers, are interested in examining the effects of interactive in-store technologies on customer behavior. An abundance of researchers have examined customer acceptance of interactive technologies, but little is known about its effects on the customer’s experience and its consequences, such as satisfaction, loyalty, and purchase intention. Following the guidelines for a systematic literature review, this article gives an overview of empirical studies conducted on interactive technologies in traditional brick-and-mortar retail stores. Based on that review, this paper provides a research agenda for future work on interactive in-store technologies and their impact on customer experience and suggests possible research methods for empirical studies in the field of human-computer interaction.

Emotional processing difficulties represent the core psychopathology of non-suicidal self-injury (NSSI), yet the underlying neural mechanisms remain unclear. To investigate neural alterations associated with emotion reactivity and regulation in individuals with NSSI and examine whether emotional valence is related to these neural patterns. During functional magnetic resonance imaging scans, unmedicated young adults with NSSI (n = 29) and matched controls (n = 25) completed an emotion regulation task in which they viewed pictures of different emotional categories with instructions to either attend to or regulate their emotions. Individuals with NSSI showed increased neural activation in the right superior temporal gyrus (STG), right parahippocampal gyrus and right supramarginal gyrus during negative emotion reactivity and increased activation in the right middle temporal gyrus and left STG during positive emotion reactivity. Conversely, those with NSSI exhibited reduced activation in the left supplementary motor area, left inferior frontal gyrus, right putamen, right thalamus and right STG during negative emotion regulation and reduced activation in the left ventral striatum during positive emotion regulation. Notably, both hyperactivation of the STG during negative emotion reactivity and hypoactivation of the supplementary motor area during negative emotion regulation were associated with emotion dysregulation in individuals with NSSI. We observed distinct neural patterns of emotional processing among individuals with NSSI, characterised by hyperactivation during emotion reactivity and hypoactivation during emotion regulation. Our findings provide a neurophysiological basis for therapeutic interventions that facilitate adaptive emotional processing in individuals with NSSI.

Introduction Mild Traumatic brain injuries (mTBIs) affect ~1–3 million people per year in the US alone. Mild TBIs can have lasting (>1 year) impacts on emotional reactivity and regulation. Sleep has also been shown to be significantly altered in individuals with a mTBI, even when tested over a year since the injury. Sleep quality is strongly linked with emotional stability and emotional memory. Therefore, one possible mediating factor between emotional reactivity and mTBIs is sleep. Reduced sleep quality following a mTBI may impair the emotional regulation that typically occurs across sleep. Thus, increasing total sleep time through a nap may help to alleviate some of the emotional symptoms. This study assessed whether individuals with a chronic mTBI showed differences in brain activity associated with emotional regulatory circuits, performance on an emotional reactivity task, and sleep physiology across a nap compared to controls. Methods Participants were 53 young adults (mTBI nap group: n=9; control nap group: n=16; mTBI wake group: n=11; control wake group: n=17). Following a nap, or an equivalent bout of wake (both recorded with polysomnography), participants completed an emotional Go/No-Go task in which they were asked to respond when a particular emotional valence was presented (neutral, fearful, or happy), and withhold a response when a different valence was presented. Results There was a significant main effect of emotion on reaction time (F(2, 98)=26.55, p < 0.001). Participants were slowest to respond to the neutral images. There was also a significant three way interaction between emotion, group, and condition (F(2,98)=4.085, p = 0.02). Conclusion While these results are preliminary, they support that both napping and mTBIs may impact emotional reactivity. Further, napping may help alleviate some of the chronic emotional dysregulation associated with mTBIs. Support Zampell Family Faculty Fellow

The serotonin transporter gene (5-HTTLPR) influences emotional reactivity and attentional bias toward or away from emotional stimuli, and has been implicated in psychopathological states, such as depression and anxiety disorder. The short allele is associated with increased reactivity and attention toward negatively-valenced emotional information, whereas the long allele is associated with increased reactivity and attention toward positively-valenced emotional information. The neural basis for individual differences in the ability to exert cognitive control over these bottom-up biases in emotional reactivity and attention is unknown, an issue investigated in the present study. Healthy adult participants were divided into two groups, either homozygous carriers of the 5-HTTLPR long allele or homozygous carriers of the short allele, and underwent functional magnetic resonance imaging (fMRI) while completing an Emotional Stroop-like task that varied in the congruency of task-relevant and task-irrelevant information and the emotional valence of the task-irrelevant information. Behaviorally, participants demonstrated the classic “Stroop effect” (responses were slower for incongruent than congruent trials), which did not differ by 5-HTTLPR genotype. However, fMRI results revealed that genotype influenced the degree to which neural systems were engaged depending on the valence of the conflicting task-irrelevant information. While the “Long” group recruited prefrontal control regions and superior temporal sulcus during conflict when the task-irrelevant information was positively-valenced, the “Short” group recruited these regions during conflict when the task-irrelevant information was negatively-valenced. Thus, participants successfully engaged cognitive control to overcome conflict in an emotional context using similar neural circuitry, but the engagement of this circuitry depended on emotional valence and 5-HTTLPR status. These results suggest that the interplay between emotion and cognition is modulated, in part, by a genetic polymorphism that influences serotonin neurotransmission.

Halal cosmetic industry is widely recognized as a significant global beauty and personal care market segment. Alongside the rapid growth, understanding consumer purchase intention toward products has become a key focus of academic investigations. Therefore, this systematic literature review aims to identify the key determinants of purchase intention and uncover prevailing trends in the context of halal cosmetic. Using the PRISMA principles, a total of 15 relevant studies were collected from the Scopus database. The results showed that purchase intention towards halal cosmetic products was influenced by various key determinants reflecting the interaction between internal and external factors. The most mentioned variables across various studies include religiosity, halal awareness, attitudes towards products, subjective norms, perceived behavioral control, as well as emotional and social values. In addition, external factors such as influencer impact, trust in halal logos, and digital marketing strategies also play a significant role in shaping purchase intention, both among Muslim and non-Muslim consumers. Based on the results, purchase intention towards halal cosmetic products cannot be explained in a single dimension, but rather from a complex dynamic between personal, psychological, social values, and exposure to marketing information. This literature not only identifies the main determinants of purchase intention for halal cosmetic products but also shows the evolving direction of investigation that is increasingly complex, interdisciplinary, and contextual, in line with the changing behaviors and expectations of modern Muslim consumers.

In recent years there has been a significant increase in digital advertising through influencers being active on many social media platforms. Budgets for influencer marketing rise yearly, and the return on investment from influencer marketing is higher than from other marketing channels. Therefore, influencer marketing is here to stay, and the pandemic has turned many customers online. Nowadays, customers most often collect information regarding products or services from influencers. The factors that may affect customers' purchase decisions are seen in influencers' credibility and advertising disclosure. A systematic literature review was done to provide an overview of the related influencer marketing field and the impact of advertising disclosure and source credibility on purchase intention. The terms ("Purchase intention") and ("influencer credibility" OR "source credibility" and “advertising disclosure”) were used to collect data. The papers were reviewed to determine how influencer credibility and advertising disclosure impact customer purchase behavior. Results indicate that influencer credibility traits positively influence purchase intention, and advertisement disclosure may impact customer purchase intention differently.

While neuromarketing research delineates how specific neurophysiological methods offer predictive power beyond traditional survey methods, few studies explore how these methods can be used concurrently to measure outcomes across marketing contexts. We address this gap by simultaneously eliciting multiple neurophysiological measures: inter‐beat interval from heart rate, skin conductance response, and frontal alpha asymmetry from electroencephalography (EEG) across multiple stimulus categories, and associating them with distinct psychological (emotional valence and arousal) and marketing (ad recognition and ad effectiveness) outcomes. We found that inter‐beat interval was associated with emotional valence while skin conductance response was associated with emotional arousal across all stimulus types. Critically, self‐reported arousal and inter‐beat interval at both the aggregate and frame level were associated with ad recognition, but self‐reported valence was not. Finally, inter‐beat interval and frontal alpha asymmetry played complementary roles in predicting out‐of‐sample ad effectiveness. Specifically, while inter‐beat interval was a significant predictor of out‐of‐sample brand recognition and not purchase intention, frontal alpha asymmetry was associated with purchase intention and not brand recognition components of ad effectiveness. Our results demonstrate distinct and complementary marketing applications for inter‐beat interval, skin conductance response, and frontal alpha asymmetry and provide valuable insights to practitioners seeking to incorporate findings from these neurophysiological methodologies into their marketing decisions.

<p><em>Online food delivery app adoption is an alternative marketing strategy for food retailing SMEs during the Covid-19 pandemic. One of the impacts of the covid-19 pandemic was the existence of psychological disorders, namely the fear of covid-19. Fear of covid-19 contributed to determining consumer behavior. This study aimed to analyze the effect of fear on purchase intention using online food delivery apps and the effect of purchase intention on purchase decisions through online food delivery apps. The research was conducted on July 2020 in Jabodetabek as Indonesia's city with an economic center. The sample used in this study was 100 samples taken by the purposive sampling method. The data were processed using SEM-PLS. This study examined three variables namely fear, purchase intention, and purchase decision. The results showed that some sub-variable of fear positively affects purchase intentions through online food delivery apps. The variables were triggers of fear, coping strategies, and functional impairment. In addition, during the Covid-19 pandemic, consumer purchase intentions significantly affected purchase decisions through online food delivery apps. The existence of the COVID-19 pandemic does not only have a psychological impact in the form of fear, but it also causes anxiety and worry. Further research can examine the effect of anxiety and worry to purchase intention and purchase decision through online food delivery apps.</em><em></em></p>
