A Study of Consumers Cognitive Load in eCommerce Websites using Eye-tracking Technology
Pith reviewed 2026-05-14 22:02 UTC · model grok-4.3
The pith
Eye tracking shows that higher prices on similar products increase cognitive load in e-commerce sites.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Using eye-tracking on 48 individuals viewing e-commerce sites, the research reveals that website complexity changes with the price of similar products, establishing a connection between visual complexity and customer perception in online buying decisions.
What carries the argument
Eye-tracking metrics including fixation count, saccades, fixation duration, and task completion time, applied to measure cognitive load from product price variations on webpages.
If this is right
- Web developers can redesign pages to minimize complexity for high-priced items.
- Business analysts gain tools to test how pricing influences user experience.
- Improved designs may lead to higher customer satisfaction in online purchases.
Where Pith is reading between the lines
- Price information might be positioned or styled differently to manage load.
- Similar methods could study other factors like product images or reviews.
Load-bearing premise
That the observed differences in eye movements are caused specifically by price differences rather than other aspects of the webpages or personal user variations.
What would settle it
Repeating the experiment with identical page layouts but altered prices showing no change in eye-tracking metrics would disprove the price-complexity link.

read the original abstract
The aesthetics of e-commerce websites have a big influence on purchasing decisions and customers' satisfaction. Webpage complexity and high cognitive load are responsible for causing an unpleasant experience while shopping online. This research empirically inspects a correlation between users' cognitive load and product pricing, where price plays a vital role in causing web complexity. Therefore, we have experimented on 48 random individuals using eye-tracking technology to observe the eye movement calibration on some reputed e-commerce websites. We measured the cognitive load extracted from users' datasets by analyzing fixation count, saccades, fixation duration, and task completion time. Our study induces new findings on website complexity which varies on the similar product but different price ranges. This research also demonstrates a strong connection between customer perception and visual complexity while making online purchases. In addition, these findings will assist the developers and business analysts to improve consumers' shopping experience in e-commerce websites.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper reports an eye-tracking study with 48 participants viewing similar products at different price points on reputed e-commerce sites. It measures cognitive load via four standard metrics (fixation count, saccades, fixation duration, task completion time) and claims that price differences induce measurable differences in visual complexity and cognitive load, with implications for website design.
Significance. If the price-complexity link could be isolated from confounds, the work would offer practical guidance for e-commerce UX. The current design, however, supplies no statistical support, no stimulus controls, and no raw data, so the central empirical claim remains unsupported.
major comments (4)
- [Methods] Methods section: the protocol provides no description of how similar products at different prices were selected or matched on layout, image count, text density, color contrast, or promotional elements; without such controls the observed metric differences cannot be attributed to price.
- [Results] Results section: no statistical tests, p-values, confidence intervals, or error bars are reported for any of the four eye-tracking metrics, leaving the claimed correlations without quantitative support.
- [Results] Results/Discussion: the analysis contains no regression controls or participant-level covariates for individual differences or page features, so the attribution of cognitive-load differences specifically to price remains untested.
- [Methods] Methods: exact websites, product categories, exclusion criteria, and data-availability statement are absent, preventing replication or assessment of generalizability.
minor comments (2)
- [Abstract] Abstract: the phrasing 'induces new findings on website complexity which varies on the similar product' is grammatically unclear and should be revised for precision.
- [Methods] The manuscript does not state whether the eye-tracking hardware and calibration procedure followed established standards (e.g., Tobii or EyeLink protocols).
Simulated Author's Rebuttal
We thank the referee for the constructive feedback that identifies key gaps in methodological transparency and statistical rigor. We will revise the manuscript to address these points directly, adding the necessary details, analyses, and controls to strengthen the empirical claims while preserving the original study design and data.

Referee: [Methods] Methods section: the protocol provides no description of how similar products at different prices were selected or matched on layout, image count, text density, color contrast, or promotional elements; without such controls the observed metric differences cannot be attributed to price.
Authors: We agree that explicit matching criteria are required to isolate price effects. In the revised Methods, we will add a dedicated subsection describing the stimulus selection protocol: products were chosen from the same category and brand where possible, with manual matching on layout structure, image count (limited to 3-5 per page), text density (word count within 10%), color contrast ratios, and exclusion of promotional banners or discounts. Only price was systematically varied across low, medium, and high conditions. revision: yes
-
Referee: [Results] Results section: no statistical tests, p-values, confidence intervals, or error bars are reported for any of the four eye-tracking metrics, leaving the claimed correlations without quantitative support.
Authors: We acknowledge the omission of inferential statistics. The revised Results section will report paired t-tests (or repeated-measures ANOVA where appropriate) for each metric across price conditions, accompanied by exact p-values, 95% confidence intervals, and error bars on all bar plots and tables to provide quantitative support for the observed differences in fixation count, saccades, fixation duration, and task completion time. revision: yes
-
Referee: [Results] Results/Discussion: the analysis contains no regression controls or participant-level covariates for individual differences or page features, so the attribution of cognitive-load differences specifically to price remains untested.
Authors: We will add multiple linear regression models in the revised analysis that include price as the primary predictor while controlling for participant-level covariates (age, gender, self-reported online shopping frequency) and page-level features (total text length, image area). This will allow us to test whether price remains a significant predictor after accounting for these factors. revision: yes
-
Referee: [Methods] Methods: exact websites, product categories, exclusion criteria, and data-availability statement are absent, preventing replication or assessment of generalizability.
Authors: The revised Methods will explicitly state the websites (Amazon.in and Flipkart.com), product categories (smartphones and wireless earbuds), exclusion criteria (color blindness, uncorrected visual impairment, or prior exposure to the exact product pages), and include a data-availability statement that anonymized eye-tracking datasets and analysis scripts will be deposited in a public repository upon publication. revision: yes
Circularity Check
No circularity: purely empirical eye-tracking measurements
full rationale
The paper reports an empirical experiment with 48 participants using eye-tracking hardware to record fixation count, saccades, fixation duration, and task completion time on e-commerce sites. No equations, derivations, fitted parameters, or self-citations appear in the provided text or abstract. Claims about price-related complexity rest on direct observational data rather than any reduction to prior inputs or self-referential definitions. This is a standard self-contained empirical study with no load-bearing circular steps.
Axiom & Free-Parameter Ledger
axioms (1)
- domain assumption Fixation count, saccades, fixation duration, and task completion time are valid proxies for cognitive load in web browsing tasks.
