People of Lower Social Status Are More Sensitive to Hedonic Product Information-Electrophysiological Evidence From an ERP Study

Changes in emotion-related EEG components and brain lateralization response to negative emotions in adolescents with nonsuicidal self-injury: An ERP study

Nonsuicidal self-injury (NSSI) is a serious risk behavior in adolescents and is a high risk factor for suicide, while negative emotions can lead to increased NSSI behaviors. In this study, we investigated the altered behavioral performance and neural reactivity of adolescents with NSSI by using a two-choice oddball paradigm when exposed to negative emotional stimuli, and analyzed the brain lateralization effect. Our data indicated that adolescents with NSSI exhibit more pronounced N250, P300, and LPP components during negative emotional face stimulation, as evidenced by a smaller N250 wave amplitude, larger P300 wave amplitude, steeper LPP waveform, and faster fallback baseline; and the presence of brain lateralization responses in both the N250 component and the LPP component. These results suggested that adolescents with NSSI showed significant alterations in cognitive EEG components associated with emotional processing during negative emotional face stimulation, particularly in EEG components representing inhibitory control, and there was a lateralization effect on emotional processing in the brain, with different processing stages and different dominance of the left and right brain.

Exploring Bottled Water Purchase Intention via Trust in Advertising, Product Knowledge, Consumer Beliefs and Theory of Reasoned Action

As the bottled water market is projected to grow continuously worldwide, so is the plastic waste that pollutes the environment. The beverage industry’s marketing campaigns have played an important role in sustaining the popularity of bottled water. Social science theory-based empirical research examining how consumers make bottled water consumption decisions remains limited. To help fill this literature gap, the current study tested a conceptual framework to explore the influence of trust in bottled water advertising and perceived product knowledge on consumer beliefs about bottled water, in conjunction with theory of reasoned action. The study surveyed a sample of college students in the U.S. (N = 445). Findings showed that greater trust in bottled water advertising as well as more false knowledge and less factual knowledge were significantly related to consumer beliefs about bottled water’s product content and image. Furthermore, more favorable cognitive beliefs, affective beliefs, attitude and perceived subjective norms toward bottled water consumption were positively related to purchase intention. To reduce bottled water purchase among young adults, it would be beneficial to utilize marketing strategies to popularize and normalize carrying a reusable water bottle as an environmentally friendly habit and a preferred lifestyle choice.
