Mackenzie has a mitsubishi tv. the company's logo appears every time she turns the tv on. however, when asked, she is unable to describe the logo. this is because of failure. if this happens, we will never remember the information.

The correct answer is encoding failure.

In terms of memory, encoding failure refers to the phenomenon where the brain fails to store some information in long-term memory. Due to this, the memory cannot be retrieved. Encoding failures typically occur when a person does not pay much attention to the information in question. In Mackenzie's instance, she is unable to describe the Mitsubishi logo because when she was exposed to the logo when she turned on the TV, she was most likely did not pay attention to it.
