Spears had already missed out on receiving photos from home during the first week.
The fact she was denied another reward could have been the final straw that tipped her decision to make a swift exit.
“Unfairness can be a very strong trigger for anger or rejection, even small acts of unfairness. People will endure a lot but not when there’s unfairness involved,” Judi told Paddy Power Games.
“When everyone is struggling equally a group can show strength and resilience, but if one or a few of that group get treated better for wrong or no reasons the rest will de-motivate or revolt.
“Jamie’s body language signalled silent upset and inner revolt from that stage on.”
The Zoey 101 star may have thought this was one injustice too far and held it against the rest of the group.
Knowing it would be a struggle to get along with the rest of her campmates from that point on, combined with her medical issues, Spears seemingly realised she was unable to continue.
“Asking Sam why he chose an apron she showed visible signs of inner anger or rejection,” James continued.
“Her smile died, she frowned and tilted her head to suggest puzzlement and her lower jaw jutted in defiance.
“Suddenly after that moment, she sat in camp in a diminished pose, self-hugging and scratching to signal distress and a desire to self-comfort.”
