A consumer is choosing between two identical brands of 0.9% NaCl IV solution. Brand A uses a 'Buy Now!' banner with bright colors (Peripheral), while Brand B provides a table showing its superior sterilization p-values (Central).

If the consumer buys Brand A and it later leaks, creating dissonance, which cognitive strategy best represents 'attitude change'?

  1. Deciding that 'all IV bags leak occasionally, so the brand doesn't matter.'
  2. Increasing the 'osmotic pressure' of the fluid to prevent further leaks.
  3. Using 'Weber's Law' to determine if the leak size is just-noticeable.
  4. Returning the bag for a refund and buying Brand B.
