It has been revealed that many online customers undergo stress when making purchases over the internet.

A psychological study from Foviance for American firm CA, found that consumers suffered greater levels of frustration and anxiety while
using poorly operated websites.

The experiment was devised in order to assess how websites can trigger emotions which affect buying behavior.

Using brain wave analysis, the procedure found that people needed to focus up to 50 per cent more.

Analysis of behavior and variations in muscle movement also showed higher levels of tension.

Catriona Campbell, founder of Foviance, said that "The results show that when online expectations aren’t met, people quickly become agitated. They also become confused, and have to concentrate 50 per cent more, than normal."
