Value Perception of Green Products: An Exploratory Study Combining Conscious Answers and Unconscious Behavioral Aspects

Previous studies have failed to provide a comprehensive view on the value perception of green products. The present research takes up this challenge through an experiment in which 43 participants have interacted with and evaluated 40 products—20 baseline products and 20 green products of the same categories. The experiment included both self-assessments to monitor conscious evaluations of the products and biometric measurements (Eye-Tracking and Galvanic Skin Response) to capture unconscious aspects. The results show that different forms of perceived value emerge clearly. Green products, for which participants required greater efforts in the search for relevant information, boost the value attributed to creative solutions still believed of high quality. This effect is significantly more evident for participants showing remarkable interest for sustainability issues. Conversely, alternative products feature greater value perception because they are acknowledged to be functional and reliable.

Physiological Sensors

Wearable sensors are increasingly used in research, as well as for personal and private purposes. A variety of scientific studies are based on physiological measurements from such rather low-cost wearables. That said, how accurate are such measurements compared to measurements from well-calibrated, high-quality laboratory equipment used in psychological and medical research? The answer to this question, undoubtedly impacts the reliability of a study’s results. In this paper, we demonstrate an approach to quantify the accuracy of low-cost wearables in comparison to high-quality laboratory sensors. We therefore developed a benchmark framework for physiological sensors that covers the entire workflow from sensor data acquisition to the computation and interpretation of diverse correlation and similarity metrics. We evaluated this framework based on a study with 18 participants. Each participant was equipped with one high-quality laboratory sensor and two wearables. These three sensors simultaneously measured the physiological parameters such as heart rate and galvanic skin response, while the participant was cycling on an ergometer following a predefined routine. The results of our benchmarking show that cardiovascular parameters (heart rate, inter-beat interval, heart rate variability) yield very high correlations and similarities. Measurement of galvanic skin response, which is a more delicate undertaking, resulted in lower, but still reasonable correlations and similarities. We conclude that the benchmarked wearables provide physiological measurements such as heart rate and inter-beat interval with an accuracy close to that of the professional high-end sensor, but the accuracy varies more for other parameters, such as galvanic skin response.

Perceived Experiences

The present study utilized an experimental method consisting of subjective and objective measures to assess physiological and psychological changes occurring during chills induced by music. Piloerection (“goosebump” formation), skin temperature; and galvanic skin response (GSR) were used to monitor peripheral nervous system changes during the response. It was hypothesized that significant changes in parameters would coincide with perceived experiences of chills when compared with other sections of music where chills were not perceived. Thirty two students (16 musicians and 16 non-musicians) were assessed while listening to music, both familiar and unfamiliar. The experiment then appeared to replicate the general experience of chills induced by music for this population. Results suggested that the experience of chills corresponded to significant changes in GSR and was associated with piloerection in some instances. No significant changes in skin temperature were evident.

BACKGROUND Preoperative services and education allow patients to take an active role in their recovery and reduce the risk of post-operative complications. Exploring patients’ perceptions and attitudes regarding pre-anesthesia services and education helps reveal gaps in patients’ uptake of them so that targeted educational interventions can be designed and implemented. OBJECTIVE This is an exploratory study aimed at increasing the understanding of patients’ perceptions and concerns about and the adequacy of the pre-anesthesia services and educational content provided to them at the pre-anesthesia clinic (PAC) of the National Guard Hospital (NGH) in Riyadh, Saudi Arabia. The information gathered will be used to design and develop an electronic patient education system that will allow patients to access personalized, evidence-based pre-anesthesia information relevant to their upcoming surgeries. METHODS Quantitative research methods are used to collect relevant information from patients using a closed-ended questionnaire. The questionnaire includes items on demographics, patients’ perceptions and concerns regarding anesthesia, and the assessment of pre-anesthesia information adequacy. RESULTS Our results showed that 94% of the participants consider the PAC very important, and more than half of the participants (56%) were interested in receiving additional educational information about anesthesia via mobile applications. While 100% of the participants were satisfied with the information and services provided at the clinic, the assessment of this information and service adequacy indicated that participants were not adequately informed about anesthesia. Among the most common anesthesia-related concerns were the inability to wake up after anesthesia, becoming paralyzed after spinal anesthesia, the possibility of staying in the ICU after the surgery and developing back pain. CONCLUSIONS This gathered information will be used to design and develop an educational intervention that will deliver evidence-based, personalized and easy to understand educational instructions to patients to better prepare them for their upcoming surgery. The proposed system will overcome the problems of (i) the spread of generalized unrelated educational information and instructions, (ii) patients forgetting or misunderstanding the given instructions, (iii) issues with the accessibility of information, and (iv) a lack of communication and interaction between patients and their anesthetist.
