“…One plausible explanation by which stressor exposure may interact with reward responsiveness leading to depression, is the down‐regulation of the PVS and its related functioning. As a crucial component of the PVS, the RewP is positively related to positive affect (Gable et al, 2021) and approach motivation to pursue rewarding goals (Pegg et al, 2021). Therefore, individuals with lower sensitivity to rewards are likely to exhibit less positive affect or have more difficulties in obtaining and utilizing reward experiences to adapt to stressful situations (Hu et al, 2022; Luking et al, 2016).…”

Both stress and blunted reward responsiveness have been identified as core risk factors of depression. Whether blunted reward responsiveness increases psychological vulnerability to real‐life stress from a dynamic perspective (from stress reactivity to recovery) has not been investigated. By utilizing a real‐world stressful event (i.e. the final examination), this study aimed to explore the role of reward responsiveness in the stress‐emotional distress relationship during stress reactivity and recovery phases. We followed 57 undergraduates with three assessments, from six weeks before examination weeks (T1, baseline), one day before the examinations (T2) to two weeks after the examinations (T3), therefore, covering stress reactivity (T1 to T2) and recovery (T2 to T3) phases. At baseline, reward responsiveness was measured as the Reward Positivity (RewP) in the doors task. Stress and emotional distress (anxiety and depression) were reported at T1, T2 and T3 to capture their dynamic changes. Results showed that self‐report stress levels significantly increased from T1 to T2 (stress reactivity phase) and decreased from T2 to T3 (stress recovery phase). Furthermore, blunted reward responsiveness at baseline prospectively predicted emotional distress during the stress reactivity phase but not the recovery phase. Specifically, during the stress reactivity phase, higher perceived stress was associated with greater anxiety and depression only in participants with relatively smaller residual RewP amplitudes but not in participants with relatively larger residual RewP amplitudes. Our study demonstrated that a blunted reward responsiveness is a vulnerable factor of depression, especially when exposed to stress. Our findings provide insights into prevention and intervention for stress‐related disturbance.

“…Other studies have examined EEG frequency bands related to approach motivation. A well-established index of affective disposition is frontal asymmetric alpha activity ( Davidson, 1998 ), considered to be inversely related to the level of cortical activation, and an EEG marker of positive affect ( Gable et al, 2021 ). Depression has been associated with an asymmetric pattern of resting-state alpha activity characterized by increased alpha in the left frontal cortex compared to the right, possibly reflecting the hypoactivation of approach-related motivation ( Allen et al, 2004 ; but see also Van Der Vinne et al, 2017 ).…”

Considering that the classical categorical approach to mental disorders does not allow a clear identification of at-risk conditions, the dimensional approach provided by the Research Domain Criteria (RDoC) is useful in the exploration of vulnerability to psychopathology. In the RDoC era, psychophysiological models have an important role in the reconceptualization of mental disorders. Indeed, progress in the study of depression vulnerability has increasingly been informed by psychophysiological models. By adopting an RDoC lens, this narrative review focuses on how psychophysiological models can be used to advance our knowledge of the pathophysiological mechanisms underlying depression vulnerability. Findings from psychophysiological research that explored multiple RDoC domains in populations at-risk for depression are reviewed and discussed. Future directions for the application of psychophysiological research in reaching a more complete understanding of depression vulnerability and, ultimately, improving clinical utility, are presented.

“…In technological shifts and embodiment, electroencephalography (EEG) stands as one of the most widely employed methods for the observation of brain activity and cognitive processes for positive effects [ 40 , 41 ]. Particularly, this technology allows the performance of a technique known as event-related potentials (ERPs), which provides a non-invasive means of collecting data that can reflect participants’ psychological activity and responses [ 42 , 43 ].…”

Packaging design is pivotal in motivating consumer decisions, as a key communication tool from creation to purchase. Currently, the interpretation and evaluation of packaging’s impact are shifting toward non-traditional methods. This pilot study evaluated the packaging perception of York Ham and Turkey Breast products. The event-related potential (ERP) technique, the methodology priming words (positive and negative), and target images (original and modified packaging) were applied. A total of 23 participants were sampled using a 32-channels scalp elastic electrode cap and viewed 200 trials of word–image matching. Participants responded whether the images and adjectives matched or not, using the two groups of images. The results demonstrate an N400 effect in the parietal area. This region was observed to show evidence of cognitive processing related to congruency or incongruency, by contrasting the priming and target of this study. The evaluation positioned the York Ham packaging as the best rated. The findings show a relevant contribution to ERPs and research related to the food packaging perception.
