R.I. R. Evid. 606

(a) At the Trial. A member of

the jury may not testify as a witness before that jury in the trial of the case in which

he or she is sitting as a juror. If the jury member is called so to testify, the opposing

party shall be afforded an opportunity to object out of the presence of the jury.

(b) Inquiry Into the Validity of Verdict or Indictment. Upon an inquiry into

the validity of a verdict or indictment, a juror may not testify as to any matter or

statement occurring during the course of the jury's deliberations or to the effect of

anything upon his or her or any other juror's mind or emotions as influencing the

juror to assent to or dissent from the verdict or indictment or concerning the juror's

mental processes in connection therewith, except that a juror may testify on the

question whether extraneous prejudicial information was improperly brought to the

jury's attention or whether any outside influence was improperly brought to bear

upon any juror. Nor may the juror's affidavit or evidence of any statement by the

juror concerning a matter about which the juror would be precluded from testifying

be received for these purposes.
