¶1We granted certiorari to review the decision of the court of appeals in People v. Wiser, No. 82CA0990 (Colo.App. Sept. 6, 1984) (not selected for official publication), affirming the conviction of the defendant, Steven L. Wiser, of first degree burglary and felony menacing after a jury trial in the Adams County District Court. The court of appeals decided that two incidents of juror misconduct during the deliberative phase of the defendant’s trial, while improper, did not require reversal of the conviction. We affirm the judgment of the court of appeals.
¶2On July 31, 1981, the defendant was charged by information with first degree burglary, felony menacing, and a crime of violence. The charges against the defendant were based on an incident on July 29, 1980, in which the defendant entered an apartment and threatened a woman with a knife as a result of a disagreement about a debt owed the defendant by the woman and her boyfriend. The case proceeded to trial and on March 24, 1982, the jury found the defendant guilty of burglary and felony menacing.
¶3In support of his motion for a new trial, the defendant submitted affidavits of the district court bailiff and the defendant’s counsel based on information they gained from an informal meeting in the judge’s chambers with the members of the jury after the jury returned its verdicts. Both of the affiants stated that they had been told by a juror that after the first day’s deliberation the juror asked a friend who was a legal secretary about the source of jury instructions.
¶4The defendant raised the juror misconduct issue, among other issues, in his appeal to the court of appeals. The court of *1141appeals agreed with the defendant that the consultation of outside sources by the jurors was misconduct, but it rejected the defendant’s invitation to presume that the juror misconduct was prejudicial. The court held that it was the defendant’s burden to show that the misconduct was prejudicial and that because the affidavits contained no indication that the jurors’ exposure to outside information actually influenced their votes, the defendant failed to carry his burden of establishing prejudice. We granted certiorari to consider the manner of proof of prejudice to the defendant when a jury receives extraneous information during deliberations.
¶5I.
¶6The court of appeals correctly determined that the resort of one of the jurors to a dictionary for a definition of the crime with which the defendant was charged was improper. Referring to a juror’s consultation of a dictionary in Niemand v. District Court, 684 P.2d 931, 934 (Colo.1984), we said, “Jurors are required to follow only the law as it is given in the court’s instructions; they are bound, therefore, to accept the court’s definitions of legal concepts and to obtain clarifications of any ambiguities in terminology from the trial judge, not from extraneous sources.” See also Alvarez v. People, 653 P.2d 1127 (Colo.1982). The other juror’s inquiry about the source of jury instructions was also irregular conduct that might hold the potential for distorting the jury’s deliberations. As Niemand and Alvarezillustrate, however, the exposure of jurors to extra-record sources of information about a case does not automatically require a new trial. Rather, the need for a new trial should be determined by evaluating the nature and circumstances of the improper contact in light of the applicable standard.
¶7Our previous cases have not provided entirely consistent guidelines for deciding whether the exposure of jurors to extraneous information or influences mandates a new trial. In most cases we have held that before a new trial will be ordered a defendant must show that the conduct complained of actually prejudiced him. See, e.g., People v. Mackey, 185 Colo. 24, 521 P.2d 910 (1974); People v. Peery, 180 Colo. 161, 503 P.2d 350 (1972); Milano v. People, 159 Colo. 419, 412 P.2d 225 (1966); Segura v. People, 159 Colo. 371, 412 P.2d 227 (1966). In People v. Boulies, 690 P.2d 1253, 1256 (Colo.1984), however, we held that the presence of an alternate juror in the jury room during deliberations “sufficiently im-pingad] upon the defendant’s constitutional right to a jury trial to create a presumption of prejudice that, if not rebutted, requires reversal.” (Footnote omitted.)
¶8The problem with both the requirement that the defendant demonstrate actual prejudice and the rebuttable presumption of prejudice approach is the difficulty, once a verdict has been reached, in obtaining evidence of actual prejudice or evidence with which to rebut the presumption because of the longstanding rule proscribing evidence concerning the mental processes of jurors. The rule is codified as CRE 606(b), which provides as follows:
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 any thing upon his or any other juror’s mind or emotions as influencing him to assent to or dissent from the verdict or indictment or concerning his mental processes in connection therewith, except that a juror may testify on the question whether extraneous prejudicial information was improperly brought to the jurors’ attention or whether any outside influence was improperly brought to bear upon any juror.
¶9Under CRE 606(b), affidavits from jurors about exposure to extraneous information or influences are admissible. The rule, however, precludes admission of the only evidence relevant to prove whether a defendant was prejudiced as a result of the improper contact. See, e.g., United States v. Greer, 620 F.2d 1383 (10th Cir.1980) (because of the limitations of FRE 606(b) a presumption of prejudice cannot be rebut*1142ted after a verdict has been returned);
¶10An approach that avoids the problems arising under CRE 606(b) requires the trial court to determine what effect juror misconduct would have had on a typical jury. See, e.g., McPhee v. People, 108 Colo. 530, 120 P.2d 814 (1941); McLean v. People, 66 Colo. 486, 180 P. 676 (1919). This objective test has been widely accepted by courts and recommended by commentators. See, e.g., Owen v. Duckworth, 727 F.2d 643 (7th Cir.1984); United States v. Vasquez, 597 F.2d 192 (9th Cir.1979); United States v. Howard, 506 F.2d 865 (5th Cir.1975); Miller v. United States, 403 F.2d 77 (2d Cir. 1968); D. Louisell and C. Mueller, supra, § 291, at 55 (1986 Supp.);
¶11We believe that the objective test of whether there is a reasonable possibility that extraneous information or influence affected the verdict should be used to determine if a new trial is required in cases like the instant one. The test is consistent with CRE 606(b)’s purpose of protecting the privacy of jurors. See M. Berger and J. Weinstein, supra, 11606[05]. The objective test is also more likely to enhance the stability of jury verdicts than an approach that required jurors to reconstruct condi*1143tions of jury deliberations and retrace their mental processes sometimes long after a verdict has been rendered. See M. Berger and J. Weinstein, supra, ¶ 606[03]. Because it eschews rebuttable presumptions that are conclusive in effect given the impossibility of rebuttal, the objective test does not require the invalidation of jury verdicts on the basis of insignificant extraneous information. Requiring a new trial where there is a reasonable possibility that the verdict was tainted by the introduction of outside information or influences into the jury deliberations will provide sufficient protection for the defendant.
¶12II.
¶13In most cases involving juror misconduct, the trial court should hold a hearing before deciding whether there is a reasonable possibility that the misconduct affected the jury’s verdict. See Owen v. Duckworth, 727 F.2d at 646; United States v. Bagnariol, 665 F.2d 877 (9th Cir. 1981), cert. denied, 456 U.S. 962, 102 S.Ct. 2040, 72 L.Ed.2d 487 (1982). In this case, however, a remand for a hearing under the objective test is unnecessary. Considering the reasonable inferences most favorable to the defendant that can be drawn from the affidavits, we fail to see how he could have been prejudiced by the conduct described in the affidavits. The only specific detail included in the affidavits about the dictionary definition of burglary resorted to by the juror was that the definition contained a reference to theft that confused the juror. It is reasonable to assume that the reference to theft and the resulting confusion, if it had any effect on the jury’s deliberations, would have favored the defendant by creating an impression that theft, which was not alleged or established by the prosecution in this case, was an element of the offense of burglary.
¶14The judgment of the court of appeals is affirmed.
¶15. Both affiants stated that the juror told them that he did not discuss the facts of the instant case with his friend.
¶16. FRE 606(b) is identical to CRE 606(b).
¶17. In an effort to avoid imposing impossible burdens of proof on either the prosecution or the defendant, some courts have interpreted Rule 606(b) to permit the introduction of evidence of jurors’ mental processes where the evidence relates to the improper exposure of jurors to outside information or influences. See, e.g., Krause v. Rhodes, 570 F.2d 563 (6th Cir.1977), cert. denied, 435 U.S. 924, 98 S.Ct. 1488, 55 L.Ed.2d 517 (1978).
¶18. Louisell and Mueller observe:
Sound post-Rules authority expresses impatience with the presumption mechanism in assessing jury misconduct. The ground of criticism is that the inability of the party defending the verdict to come up with evidence dislodging the presumption (most such evidence being of the sort which FRE 606(b) would bar), coupled with the fact that much jury misconduct seems harmless and trivial, forces courts into artificial inquiries as to whether the conduct is of the sort which brings the presumption into play in the first instance. Clearly the real question is whether the misconduct probably affected the verdict (or, and this seems to be nearly the same thing, whether there is any "reasonable possibility" of such effect), (footnote omitted).
¶19Federal Evidence § 291, at 55 (1986 Supp.).
¶20. Some courts applying the objective test, the determination of what effect juror misconduct would have had on a reasonable jury, have stated that reversal is required where there is the "slightest possibility" that a typical juror would have been affected. See United States v. Marx, 485 F.2d 1179, 1184 (10th Cir.1973), cert. denied, 416 U.S. 986, 94 S.Ct. 2391, 40 L.Ed.2d 764 (1974); Dallago v. United States, 427 F.2d 546, 560 (D.C.Cir.1969); United States v. Adams, 385 F.2d 548, 550-51 (2d Cir.1967).
¶21. The defendant was convicted of first degree burglary under section 18-4-202, 8B C.R.S. (1986), which provides:
(1) A person commits first degree burglary if he knowingly enters or remains unlawfully in a building or occupied structure with intent to commit therein a crime, other than trespass as defined in this article, against a person or property, and if in effecting entry or while in the building or occupied structure or in immediate flight therefrom, he or another participant in the crime assaults or menaces any person, or he or another participant is armed with explosives or a deadly weapon.
