AI Article Synopsis

  • The research investigates experiential consumption, particularly the IKEA effect, where people are willing to pay more for DIY products due to the positive experience of assembling them.
  • The study utilized functional near-infrared spectroscopy (fNIRS) to measure brain activity in healthy students during a willingness to pay (WTP) evaluation after assembling DIY products.
  • Findings highlighted increased activation in brain regions like the left-middle frontal gyrus (L-MFG) during DIY evaluations, suggesting specific cognitive processes linked to the IKEA effect.

Article Abstract

Introduction: In recent years, experiential consumption, which refers to purchases involving hedonic experiences, has been gathering attention in marketing research. Experiential consumption is closely related to cognitive biases, and among them, we focus on the IKEA effect, which is a cognitive bias in which the maximum willingness to pay (WTP) for a product is high because the experience of assembling the product is highly valued. Since no studies have examined the neural mechanism behind the IKEA effect, here we present the first study exploring the neural substrates of the IKEA effect using functional near-infrared spectroscopy (fNIRS). During the WTP evaluation, we expect the attachment to and memory retrieval of DIY products to be the cognitive mechanism for the IKEA effect.

Methods: Thirty healthy students, of which 24 were confirmed to have undergone the IKEA effect, were asked to perform a WTP evaluation task after assembling three types of do-it-yourself (DIY) products and handling three types of Non-DIY products. Their cerebral hemodynamic responses during the evaluation were measured using fNIRS. In order to adjust for temporal variability of cortical responses among participants, a personalized adaptive general linear model (GLM) analysis was adopted. Then, one-sample -tests were performed for each DIY and Non-DIY condition for the obtained β values, and a paired -test was performed between DIY and Non-DIY conditions.

Results: We identified brain regions, including the left-inferior frontal gyrus (L-IFG) and left-middle frontal gyrus (L-MFG), which were probably related to cognitive processing related to the IKEA effect. Among them, the L-MFG exhibited more activation during the DIY condition than during the Non-DIY condition.

Conclusion: To our knowledge, the current study is the first to reveal the neural basis of the IKEA effect. The cortical activation during evaluation of WTP for DIY and Non-DIY products exhibited marked differences. In addition to the R-IFG activation often reported for WTP evaluations, we revealed that other regions, in particular the L-IFG and L-MFG, were activated during the DIY condition. These areas are considered to be related to memory and attachment, which would serve as reasonable cognitive constituents for the IKEA effect. In conclusion, this study suggests that the value of experiential consumption can be assessed using fNIRS-based neuroimaging and provides a novel approach to consumer neuroergonomics. It is predicted that visualization the value of experiential consumption will create marketing opportunities for more and more companies and the visualization will become an indispensable method in the future.

Should digoxin immune fab be administered based solely on reported ingested amount in acute digoxin poisoning?

Acute digoxin poisoning is increasingly uncommon in emergency medicine. Furthermore, controversy exists regarding indications for antidotal digoxin immune fab in acute poisoning. In healthy adults, the fab prescribing information recommends administration based on "known consumption of fatal doses of digoxin: ≥10mg," while many emergency medicine textbooks suggest fab administration be driven by clinical features or potassium concentration.

Integrating artificial intelligence (AI) into critical domains such as healthcare holds immense promise. Nevertheless, significant challenges must be addressed to avoid harm, promote the well-being of individuals and societies, and ensure ethically sound and socially just technology development. Innovative approaches like Embedded Ethics, which refers to integrating ethics and social science into technology development based on interdisciplinary collaboration, are emerging to address issues of bias, transparency, misrepresentation, and more.

Objectives: To explore physiotherapists' experiences and perceived acceptability of delivering a bracing intervention for knee osteoarthritis (OA) in the 'PROvision of braces for Patients with knee OA' (PROP OA) randomised controlled trial.

Method: Semi-structured telephone interviews with consenting physiotherapists who received the PROP OA training programme and delivered the knee bracing intervention (advice, information and exercise instruction plus knee brace matched to patients' clinical and radiographic presentation and with adherence support). Interviews were recorded and transcribed verbatim.

This research investigates the empirical effects of the laser land leveling (LLL) adoption on irrigation water and water efficiency in paddy production in the Mekong Delta region (MDR), using the randomized controlled trial (RCT) approach incorporated into input demand function models. The descriptive analysis highlights the potential for water reuse through farmers' drainage practices. However, the dependence on experiential methods for applying technology in paddy production poses challenges that could compromise long-term sustainability.
