Certain dolphins have larger prefrontal cortices with more neurons, are highly intelligent with the ability to predict and long term memory yet seem to lack what we think is a unique human capacity for first person introspective meta-cognition. Which is essentially what most and this article mean when talking about the hard problem or qualia.

We can also look at chimpanzees. They have a prefrontal cortex, future prediction and long term memory. While their prefrontal cortex is smaller, it is also the most human like. Yet, they too seemingly lack capacity for that human style of conscious being. There is alas, something more your definition has failed to touch upon.
