SDT, Implicit Memory, and Career

An Individual's implicit memory refers to the unconscious "memory" of previously acquired information without conscious participation or deliberate recall. (Graf, Schacter,1985) For example, a strange name popped up in your mind, and when you search it online, you find that it is the name of a restaurant thousands of miles away – what a coincidence! But the truth is, you must have heard the name sometime before that it leads to the creation of your implicit memory, you don't even know it.

As mentioned in Assignment 2, Signal Detection Experiment (SDE) can extract and evaluate one's sensitivity (d'). Therefore, SDE is a suitable choice for verifying implicit memory by finding out the connection between d' and implicit stimulation.

For details, you can check: Comparing direct (explicit) and indirect (implicit) measures to study unconscious memory.

Another article I'd like to share is "Career lessons and observations for starting off in the UX field," written by Kitty Z Xu, who is a Pinterest UX designer as well as a former researcher in neuroscience. Xu talked about many differences between scientific research in the lab and commercial works that people might ignore, which is quite instructive for students.
