To my knowledge, they are somewhat different.

Investigator effects are characteristics of the investigator (e.g. age, gender , ethnicity) or the deliberate manipulation by the investigator that can affect the results. For example, female interviewees may not disclose information when asked questions about harrasment because of the interviewer being of male gender. An example of a more active involvement of the investigator would be that they may interpret the data so it fits their hypothesis, even when really this may not be the case.

Observer effects are where the presence of the observer or the participants knowledge that they are being observed can affect the way they act and thus affect results (more commonly known as the Hawthorne effect). For example, if a researcher undergoes an overt non-participant observation of a criminal gang, the gang members may act less aggressive because of this which does not reflect how they would normally act.

I hope that helps!
