In a study, two groups of individuals are repeatedly shown a neutral image (a blue square) immediately followed by a loud, startling noise. Group A consists of individuals who have previously experienced severe trauma, while Group B has no such history. Researchers observe that Group A begins showing a strong fear response to the blue square alone after only a few pairings, whereas Group B takes many more pairings to show a similar response. In a later phase, when the blue square is shown repeatedly without the noise, Group A's fear response diminishes very slowly, while Group B's fear response fades quickly. Which statement best analyzes the learning patterns observed in Group A compared to Group B?
