When considering new products, anxiety creates approach response (i.e., interest, purchase) rather than avoidance response (i.e., disinterest, failure to purchase) when consumers hope for the goal-congruent outcomes.

Companies across the world are competing fiercely to provide high-resolution displays to electronic devices such as TVs and smartphones. In particular, the virtual reality, a keyword of the 4th industrial revolution, requires a much higher resolution to improve the picture quality. A Korean research team developed a technology to produce a 'nano display' with a phenomenal resolution based on the...
