Description

Psychological research frequently relies on Likert-type questionnaires to collect data on psychological traits. While cost-effective and straightforward, the cognitive effort required to complete these questionnaires and the related stress response, known as "response burden," can affect data quality. Response burden includes factors like questionnaire length, complexity, emotional intensity, and presentation format. Our study focuses on the affective correlates of response burden by evaluating its psychophysiological effects. We measured Galvanic Skin Response (GSR) and facial electromyography (EMG) of the zygomatic and corrugator muscles during the completion of two personality tests based on the Big Five theory—one shorter with 44 items and another longer with 132 items. GSR is an indicator of arousal, defined as peripheral sympathetic activation which is linked to emotional engagement or stress. Facial EMG assesses muscle activity: in particular, corrugator muscle activation is linked to the expression of affective states with negative valence, while zygomatic activation is linked to affective states with positive valence. These measures provide insights into how the response burden impacts participants’ affective states. To analyze the data, we employed multimodal artificial neural networks, which can integrate various data types, including physiological signals, response times, and direct responses. We hypothesize that there will be changes in respondent affective states due to the response burden, particularly in the latter part of the longer questionnaire. Our approach highlights the importance of multimodal analysis when exploring complex psychological phenomena and emphasizes the need to design questionnaires that take into account the response burden and its psychophysiological correlates.
