Preparedness refers to the tendency to form associations more readily with certain types of stimuli due to innate predispositions. Which statement reflects this concept?

• A. All stimuli are equally easy to pair
• B. Some stimuli are more easily associated than others due to innate biases
• C. Learning is random and not influenced by biology
• D. Only rewards influence learning

Answer: (B)

Preparedness captures how biology biases learning, making some stimulus–outcome pairings easier to form than others. Because certain associations have been crucial for survival through evolution, organisms are predisposed to link particular types of cues with specific outcomes more readily. For instance, many animals quickly form taste–illness associations (a taste aversion) or fear responses to those natural threats that historically signaled danger. This means learning isn’t random or evenly easy across all possible cues; some stimuli are inherently more learnable due to innate biases. That’s why the statement that some stimuli are more easily associated than others, because of these biases, best reflects preparedness. The other ideas—that all stimuli are equally easy to pair, that learning is random and biology doesn’t influence it, or that only rewards drive learning—ignore these biological constraints and don’t fit how preparedness shapes learning.
