Ashley is described as academic, inquisitive and forthright. She dislikes horror movies and dreams of being an author.
While Ashley did partake in the prank against Hannah Washington, she had the least involvement of the pranksters, being a mere onlooker. She can be repentant about participating in the prank, but she can also be dismissive and lay the blame with Hannah, claiming she overreacted.
Ashley is shown to be very observant, yet she is also easily scared due to her wild imagination. As the night progresses, she becomes increasingly panicky, freaked out by the seemingly supernatural events taking place. As such, she at times demonstrates reluctance in looking for Sam when the latter is missing, though Chris can usually convince her to continue and even show courage in the face of a potential threat. Still, when in actual danger, Ashley is not as quick on her feet as Mike or Emily; this is shown when she manages to stab the Psycho in the shoulder with a pair of scissors, but then fails to follow up on this attack or escape.
