executive self

the subjective agent to which regulation and implementation of voluntary actions is ordinarily attributed. The concept of an executive self has acquired considerable scientific plausibility, being associated with well-studied functions of the prefrontal cortex and other brain structures. Self-descriptions are vulnerable to a variety of attribution errors, however (see illusion of agency).

ascertainment bias

ascertainment bias

error in selecting individuals or units for a sample, such that those units selected are not representative of the relevant population. For example, a medical researcher who studies a sample of patients that omits certain types of people who have the disorder of interest is likely to obtain results having an ascertainment bias. The term is often preferred over sampling bias in clinical contexts.
