OPINION
Kenneth Bruce Perkins appeals his convictions of four counts of aggravated sexual assault of a child. The jury found Appellant *92 guilty and assessed his punishment at 30 years’ imprisonment and a $5,000 fine for each count. We affirm.
Appellant was charged by two multi-count indictments with the aggravated sexual assault of two of his minor grandchildren, and the cases were tried in a single proceeding before a jury. The indictment in the instant case concerns the sexual assault of J.B.P., who was five years old at the time of trial on the merits. Appellant and his wife, Carol Perkins, have two sons, Larin and Lann. Larin is married to Patricia Ann “Trish” Perkins, while Lann is married to Patty J. Perkins. J.B.P. is one of Larin and Trish’s three children. A.P. is the only child of Lann and Patty. Appellant attempted to show at trial that Trish and Patty had improperly influenced the complainants to level these accusations because the two women did not like Appellant and his wife. The trial below was emotional, hotly contested, and contentious.
EXCULPATORY POLYGRAPH EVIDENCE
By his first two points of error, Appellant challenges the trial court’s exclusion of exculpatory polygraph evidence showing that Appellant had passed a polygraph examination with regard to these accusations. In Point of Error No. One, Appellant contends that the per se exclusion of polygraph test evidence violates his rights to due process, compulsory process, and to testify in his own behalf as guaranteed by the Fifth, Sixth, and Fourteenth Amendments to the United States Constitution. In Point of Error No. Two, he asserts that the trial court abused its discretion in applying the per se rule to exclude the polygraph evidence at his trial because it would have bolstered his credibility and called into question the credibility of the State’s witnesses. Appellant contends that this evidence is admissible pursuant to Rule 702 of the Rules of Criminal Evidence.
Underlying Facts
Outside the presence of the jury, Appellant offered the testimony of Ernie Hulsey, a certified polygraph examiner employed by the Harris County Sheriffs Department. Appellant developed through Hulsey the scientific basis and reliability of polygraph testing and its acceptance in the scientific community. Hulsey also testified with regard to his specialized training, knowledge, and experience as a certified polygraph examiner. Hulsey then testified specifically with regard to his polygraph examination of Appellant which concerned the accusations in this case. 1 He told the trial court that he did not detect any deceptive responses by Appellant during the test and he also offered a direct opinion that Appellant was telling the truth. The trial court excluded the evidence on the ground that it is not admissible “under our present rulings.” Appellant later testified before the jury and denied committing the conduct alleged in the indictments.
Standard of Review
The decision whether to allow the testimony of an expert witness is within the sound discretion of the trial court.
Duckett v. State,
Per Se Exclusion of Polygraph Evidence Prior to Adoption of Rules of Criminal Evidence
It has long been the rule in Texas that polygraph evidence is inadmissible on behalf of the State or the defense due to the inher
*93
ent unreliability of the evidence and its tendency to be unduly persuasive.
See e.g., Tennard v. State,
Admissibility of Polygraph Evidence After Adoption of Rules of Criminal Evidence
We agree with Appellant that the admissibility of evidence must be analyzed according to the Rules of Criminal Evidence.
See Long v. State,
The threshold determination for admitting expert testimony is whether the testimony will assist the trier of fact to understand the evidence or to determine a fact in issue. Tex.R.CRIM.Evtd. 702;
Kelly,
Applying the above principles, the Court of Criminal Appeals has held that expert testimony that a particular witness is truthful is inadmissible under Rule 702 because it does not concern a subject upon which the testimony of an expert would
assist
the trier of fact.
Yount,
Is Per Se Exclusion of Exculpatory Polygraph Evidence Constitutionally Permissible?
We turn our attention now to Appellant’s contention that a per se exclusion of polygraph evidence due to unreliability is constitutionally impermissible because it violates his right to present evidence material to his defense. It is undisputed that a person charged with a crime has the right to defend himself.
Fuller v. State,
The right to present relevant testimony is not without limitation.
Rock v. Arkansas,
Upon examining the per se exclusion of polygraph evidence in this light, we first observe that there is no evidence that the exclusion of polygraph evidence disadvantages the defendant more severely than the State. In fact, the State would be greatly benefitted if it could bolster the credibility of its witnesses at trial through the use of expert testimony. Second, there is no showing that the rule arbitrarily excludes reliable defensive evidence without achieving a superior social benefit. Even though serious doubts remain about the reliability of polygraph evidence, 3 its unreliability is not the primary reason for its exclusion under our holding. Instead, we find that such evidence should be excluded because it impermissibly decides the issues of credibility and guilt for the trier of fact and supplants the jury’s function. 4 *95 Certainly, society has a legitimate interest in insuring that the credibility of witnesses, and ultimately, the guilt of an accused person, is decided only after the trier of fact has given due consideration to all the evidence in a ease. Until such time that polygraph evidence is so rehable that we are willing to allow it to take the place of the trier of fact, then this exclusion of polygraph evidence under Ride 702 should remain intact.
For ah of these reasons, we find that the per se exclusion of polygraph evidence is constitutionally permissible and that the trial court did not abuse its discretion in excluding the evidence in this case. Points of Error Nos. One and Two are overruled.
CONSTITUTIONALITY OF TEX. GOV’T CODE ANN. § 74.053(b)
In Point of Error No. Three, Appellant contends that Article 74.053(b) of the Texas Government Code, as applied in this case, denies him equal protection of the law because it permits civil litigants to recuse assigned former judges automatically, but does not afford criminal defendants that same power. Tex.Gov’t Code Ann. art. 74.053(b) (Vernon Supp.1995);
see Lanford v. Fourteenth Court of Appeals,
The same constitutional challenge made by Appellant in the instant case has previously been rejected by the Thirteenth Court of Appeals in the above-cited case of
Garcia v. State.
In that case, the Court found the policy discussion in
Lanford
instructive in finding a rational basis for the legislature’s decision to grant only civil litigants the right to peremptorily challenge former judges.
Garcia,
Appellant argues that the policy found in
Lanford,
that is, the State would gain inordinate power if given the right to peremptorily challenge visiting former judges in criminal cases, does not apply to him because an individual defendant is obviously not a party to every criminal case. Thus, he seems to suggest that the right should be given criminal defendants, but denied the State. Similar arguments were raised by the appellant in
Garcia
and rejected for two reasons which we find persuasive. First, the Court of Appeals found that the State has legitimate interests in disposing of its criminal prosecutions in a timely manner, in controlling inmate populations, and in alleviating overcrowded jails.
Garcia,
PROSECUTORIAL MISCONDUCT
In his fourth point of error, Appellant, complaining of various acts on the part of the prosecutor, alleges that the trial court erred in failing to grant his motion for mistrial due to prosecutorial misconduct. In order to preserve error in cases of prosecuto-rial misconduct, the defendant must (1) make a timely and specific objection; (2) request an instruction that the jury disregard the matter improperly placed before the jury; and (3) move for a mistrial. Tex.R.App.P. 52(a);
Cook v. State,
Claims of prosecutorial misconduct are determined on a case by case basis.
Stahl v. State,
Turning our attention to the merits of the three complaints in which error is preserved, Appellant first complains that the prosecutor asked Carol Perkins whether she possessed any battery-operated sexual devices (dildos) in violation of an instruction by the court. Appellant does not point to any place in the record in which it is affirmatively shown that the court had instructed the prosecutor to not raise this matter before the jury. Our review of the rather lengthy appellate record 5 does not reveal that such an instruction had been given. While the trial court had not permitted the State to elicit from Patty Perkins that she had seen such devices in Appellant’s home, the court did not instruct the prosecutor that she could not raise this subject through other witnesses. 6 In fact, the court took the State’s subsequent re-offering of this evidence under advisement on two occasions, but never made a ruling thereon. Consequently, the record does not support Appellant’s claim that the prosecutor deliberately violated a court order or instruction. Further, there is no evidence that the question was clearly calculated to inflame the minds of the jury or that it was of such a character so as to suggest the impossibility *97 of withdrawing the impression produced. Given that the jury had already heard that Appellant had used dildos to assault both children and that Appellant had attempted to discredit A.P. by showing that she had made up a story about a “chopped off penis,” the prosecutor’s efforts to show that Appellant and his wife possessed dildos in their home similar to those mentioned by the children was a legitimate area of inquiry. Appellant’s first contention is without merit.
Next, Appellant asserts that the prosecutor violated his right to a fair trial by impermissibly questioning Appellant during cross-examination whether he had ever bullied anybody. When Appellant denied it, the prosecutor asked him whether he knew a person named “Michael Craig.” Outside the presence of the jury, it was revealed that Appellant had assaulted a police officer named Michael Craig. The State sought to introduce this evidence to rebut the testimony of defense character witnesses that Appellant was not a “bully.” The trial court sustained Appellant’s objection based upon Rule 404(b) and instructed the jury to disregard the evidence. However, the court denied Appellant’s motion for mistrial. Subsequently, the court did not permit Michael Craig to testify with regard to his opinion of Appellant’s veracity and peaceful nature.
Appellant has failed to show that the prosecutor’s question, “Who is Michael Craig?” was clearly calculated to inflame the minds of the jury and was of such a character so as to suggest the impermissibility of withdrawing the impression produced. It is not at all clear from the jury’s perspective that the question referred to a specific instance of bad conduct on Appellant’s part. Further, even if we assume that the question had any prejudicial effect, the trial court’s instruction to the jury to disregard was sufficient to remove its impact.
Finally, Appellant contends that the prosecutor committed prosecutorial misconduct during cross-examination of a defense witness. The witness testified on direct examination that Trish had told her that she did not like Appellant and his wife because she thought they were “white trash.” In an effort to expose whether the witness knew the specific basis for Trish’s dislike of Appellant, the prosecutor asked the following question:
Q: Did she [Trish Perkins] tell you about the sexual innuendos and sexual comments—
Before the prosecutor could complete the question, however, Appellant requested a hearing at the bench. The court sustained Appellant’s objection and instructed the jury to disregard the question, but denied Appellant’s motion for mistrial.
We do not find that the prosecutor deliberately violated a court order or that her conduct bordered on being contumacious. In fact, the prosecutor’s question had reference to matters which were already in evidence in that Trish had testified earlier in the trial that she felt uncomfortable around Appellant because of sexual comments he made to her. Considering that the prosecutor only partially asked the question before Appellant objected, there is no evidence that the resulting prejudice, if any, could not be cured by the court’s instruction to disregard. Consequently, this contention is without merit. For all of these reasons, Point of Error No. Four is overruled.
EXCLUSION OF CHILD-WITNESS TESTIMONY DURING PRETRIAL HEARING
In Point of Error No. Five, Appellant contends that the trial court erred in excluding material and favorable evidence by not permitting him to call several child witnesses
7
to testify at a pretrial hearing. In a related contention, Appellant argues in his sixth point of error that the trial court, by excluding this testimony, violated Appellant’s rights guaranteed by the Fifth, Sixth, and Fourteenth Amendments. We need not reach the merits of Appellant’s contentions because he has faded to preserve error. Rule 103(a)(2) of the Rules of Criminal Evi-
*98
denee provides that error may not be predicated upon a ruling of the court excluding evidence unless the substance of the evidence was made known to the court by offer. Tex. R.CRIM.Evid. 103(a)(2);
see Chambers v. State,
STATEMENTS BY APPELLANT
Appellant asserts in Points of Error Nos. Seven and Eight that the trial court erred in admitting certain statements he had made to Larin Perkins. We will address these contentions separately. In Point of Error No. Seven, Appellant complains of the admission of his statements, including one made about his brother who had been convicted of child molestation, on the ground that his statements were hearsay. J.B.P.’s therapist told Larin that J.B.P. might have been sexually molested by an adolescent family member and by an unknown adult male. Larin testified that when he repeated what he had learned to Appellant and other family members, Appellant made the following comments which disturbed Larin:
A: My father and — you know, they were all there; so, you can ask everybody. He said—
[Appellant’s hearsay objection overruled]. A: At that point he said, “I can’t believe this is all happening.” He said, “I’m not sick like my brother.”
[Appellant objected again on the grounds of hearsay and Rules 403 and 404(b). Although his objections were overruled, the trial court did not allow the prosecutor to elicit from Larin that the brother had been convicted of molesting a child and sentenced to prison.]
Q: In the same conversation — or in the same breath that your dad said— made the statement—
[Appellant reurged his prior objections, but the trial court overruled them.]
Q: Did he say something else to you right after he made the statement you already testified to?
A: Yes, ma’am.
Q: What was that?
A: He said, “I hope you don’t blame us.”
We find that the above testimony is not hearsay for two reasons. First, the State did not offer Appellant’s out-of-court statements for the truth of the matter asserted. Hearsay is a statement, other than one made by the declarant while testifying at the trial or hearing, offered in evidence to prove the truth of the matter asserted. Tex.R.CRIM. Evid. 801(d). If the out-of-court statement is relevant only if the trier of fact believes that the statement was both truthful and accurate, then the statement is hearsay.
Bell v. State,
Second, Appellant’s statements to Larin are exempted from the hearsay rule under Rule 801(e)(2)(A), which provides that a statement is not hearsay if the statement is offered against a party and is his own statement. Tex.R.CRIM.Evid. 801(e)(2)(A);
Bell,
In Point of Error No. Eight, Appellant contends that the trial court abused its discretion under Rule 403 in determining that the danger of unfair prejudice did not substantially outweigh the probative value of Appellant’s statements about his brother.
8
The approach under Rule 403 is to admit relevant evidence
unless
its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, or needless presentation of cumulative evidence. Tex.R.CRIM.Evid. 403;
Long,
In conducting the balancing test required by Rule 403, the trial court must assess the inherent tendency (if any) of the evidence to encourage resolution of material issues on an improper basis, and then must balance against that inherent tendency the host of factors affecting probativeness, including the relative weight of the evidence and the degree to which its proponent might be disadvantaged without it.
Richardson v. State,
Appellant argues that this evidence had an undue tendency to encourage resolution of the issue of Appellant’s guilt on an improper basis, that is, on the basis that there was a familial propensity to molest children.
9
While it is arguable that there is a general tendency to evaluate others in light of their family members’ general character, we find it unlikely that the jury, simply because it could have inferred that Appellant’s brother had committed a similar offense, would have decided Appellant’s guilt on that basis. The evidence was offered to show a consciousness of guilt, not a familial propensity to commit this type of offense. The State argues on appeal, as it did at trial, that the evidence possesses significant probative value because it shows a consciousness of guilt on Appellant’s part in that he immediately became defensive when told of the molestation of his granddaughter. A consciousness of guilt is perhaps one of the strongest kinds of evidence of guilt.
Torres v. State,
Appellant also argues that the State did not need the evidence to prove guilty knowledge, because the complainants’ accounts, if believed, were sufficient in and of themselves for that purpose. This contention is without merit. Appellant defended these charges on the basis that the complainants made their charges due to improper suggestions made by others. Under these circumstances, showing that Appellant possessed a consciousness of guilt even before the complainants had identified him as their assailant was relevant and important to the prosecution. Thus, the State would have been significantly disadvantaged if not permitted to introduce this evidence. We find that the trial court did not abuse its discretion in concluding that the probative value of this evidence was not substantially outweighed by the danger of unfair prejudice. Point of Error No. Eight is overruled.
CHARACTER EVIDENCE
In his ninth point of error, Appellant asserts that the trial court erred in admitting testimony by Trish Perkins that Appellant lacked the morals and values of a “straight-laced church-going individual” because it constituted improper character evidence. In explaining her relationship with Appellant and Carol Perkins, Trish testified that she felt uncomfortable around Appellant at times due to things he said to her. Trish stated that when she first met her husband’s family, her in-laws described her as a straightlaced church girl. She then went on to testify that she did not feel comfortable around Appellant because she felt he had different values and morals than she did. Appellant objected that the evidence constituted improper character evidence. The court ruled that the witness could testify generally that she believed Appellant had different moral values, but she could not relate any specific instances that formed the basis of her opinion.
It is well established that evidence of a person’s character or a trait of his character is generally not admissible for the purpose of proving that he. acted in conformity therewith on a particular occasion. Tex.R.CRIM.Evid. 404(a). Under these facts, however, we do not agree that the jury would have necessarily drawn an adverse or negative inference about Appellant’s character from this portion of Trish’s testimony. She did not testify that Appellant lacked the values of a “straight-laced church-going individual,” but rather, that Appellant had different values and morals than she did. The fact that a person has different values than a church-going individual does not necessarily mandate a conclusion that the person lacks values or is immoral. As such, the evidence in question did not show that Appellant possessed a bad character trait. Point of Error No. Nine is overruled.
DISCOVERY ORDER
In Point of Error No. Ten, Appellant contends that the visiting judge violated his right to due process by failing to enforce a discovery order entered by the judge who originally presided over the case. 10 More specifically, Appellant complains that he was not provided prior to trial with copies of *101 “notes” made by three therapists who treated the complainants and another child witness until after the witnesses’ direct examinations were concluded at trial. His complaint in this regard is two-fold: (1) the State deliberately failed to comply with the discovery order deadline; and (2) the visiting judge did not enforce the discovery order when requested to do so. Both contentions are without merit.
Criminal defendants are entitled to limited discovery under Article 39.14 of the Code of Criminal Procedure, independent of the constitutional right of access to exculpatory evidence.
Kinnamon v. State,
With regard to Appellant’s first complaint, we find that the trial court did not provide for any deadline by which the State had to comply with the discovery order. A deadline is found in Appellant’s proposed discovery order, but he did not obtain the trial court’s signature thereon. Appellant did not request in either his motion or at the pretrial hearing that the court set this deadline, or otherwise set the time, place, and manner for completing the discovery process.
See
Tex. Code CRIM.PROC.Ann. art. 39.14 (Vernon 1979);
see also Kinnamon,
Appellant also complains that the visiting judge erred by failing to require the State to turn over copies of the therapists’ notes just prior to trial. The court ruled instead that the State would be required to turn over the therapists’ files on the day they testified. In ruling that the State did not have to physically turn over copies of the notes until after the witnesses concluded their direct examination, the trial judge impliedly concluded that the notes did not contain exculpatory or mitigating material, and further, that they were statements of the witnesses which did not have to be produced until after the witnesses concluded their direct examination. See Tex. R.Crim.Evid. 614(a); Tex.Code CRIM.PROC. Ann. art. 39.14 (Vernon 1979). We are unable to determine whether the trial court abused its discretion in reaching these conclusions because Appellant failed to have the therapists’ notes admitted into evidence below and included in the appellate record for our review. Point of Error No. Ten is overruled.
FAILURE TO PRESENT EXCULPATORY EVIDENCE TO GRAND JURY 11
In Point of Error No. Eleven, Appellant complains that his conviction is invalid because it is based upon a constitutionally infirm indictment due to the fact that the prosecutor failed to present exculpatory evidence to the Grand Jury. Appellant did not raise this complaint in the context of prosecutorial misconduct. Rather, he filed a motion to quash the indictment on this ground prior to trial which the trial court denied without a hearing. We find it unnecessary to review the merits of Appellant’s attack on the indictment. If an indictment is valid on its face, as in the instant case, an appellate court may not go behind the indictment to determine whether the indictment was properly returned or to review alleged procedural errors in its presentment.
DeBlanc v. State,
PERJURED TESTIMONY
In Points of Error Nos. Twelve and Thirteen, Appellant contends for the first time on appeal that his conviction should be reversed because it was procured through the use of peijured testimony by one of the State’s expert witnesses. Specifically, Appellant claims that Dr. Robert McLaughlin committed aggravated perjury by testifying falsely with regard to the findings of a scientific study, committed a fraud upon the court, and breached his ethical duties as a psychologist. Even though Dr. McLaughlin did not identify the study to which he referred in his testimony, Appellant maintains that he could have been referring to only one of two studies. He has attached copies of those studies to his supplemental brief.
It is clear that the State is not allowed to obtain a conviction through the knowing use of perjured testimony.
Losada v. State,
We find that the record does not support Appellant’s contention. The studies he has attached to his supplemental brief were not introduced at trial. Accordingly, the State correctly contends that this Court may not consider the studies because they are not part of the appellate record.
See Young v. State,
CONCLUSION
Having overruled all of Appellant’s points of error, the judgment of the trial court is affirmed.
Notes
. Although Hulsey had before him while testifying a copy of the questions he asked and Appellant's answers, the record does not contain a copy of that document. The prosecutor repeated several of the questions and Appellant's answers during cross-examination. From that exchange, we gather that Appellant denied any sexual contact or conduct with the victims.
. Rule 702 provides: If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise. TexR.Crim.Evid. 702.
. Notwithstanding Appellant's claims that polygraph examinations and results are more reliable today due to the fact that polygraph examiners are more competent than in times past, the theory and methodology behind polygraph examinations has remained unchanged since
Romero.
In administering this polygraph examination, Hul-sey measured changes in Appellant’s blood pressure, heart rate, respiratory function, and galvanic skin response. These are the same physiological responses measured in
Romero. See Romero,
. This concern was also expressed in pre-rules cases.
See e.g., Romero,
. The appellate record consists of eighteen volumes of statement of facts containing 3,439 pages, and two transcript volumes consisting of 368 pages.
. Evidence introduced without objection earlier in the trial showed that both complainants had said that Appellant used dildos in some of the assaults. A.P. told her mother that she had seen Appellant’s penis and she had also seen a "chopped off" penis that moved. A.P. said that Appellant had touched her vagina with the "chopped off” penis. Similarly, the jury heard testimony that J.B.P. had reported that Appellant had put "toys” or a “statue” that moved inside her bottom. The State unsuccessfully attempted to establish through Patty Perkins that she had seen dildos, including one similar to the one described by A.P. as a "chopped off penis,” in Appellant’s home. The second offering of this evidence occurred after Appellant questioned Patty about the “chopped off penis" and suggested that A.P. had falsely accused Appellant of chopping off a dog’s penis and squirting blood out of it. The State requested again that it be allowed to ask Patty whether she had seen any dildos in Appellant's home in order to correct the *97 false impression that Appellant had left with the jury-
. These children were either related to the complainants or were their playmates. At the time of the hearing, all but two of these children ranged from four years to six years of age; the other two children were eleven years old and fourteen years old.
. Although Appellant also objected at trial on the basis of Rule 404(b), he does not advance that claim on appeal. In fact, he concedes that Rule 404(b) is inapplicable because the evidence does not involve any extraneous conduct on his part. Appellant did not object at trial that the evidence was irrelevant under Rule 401. Consequently, we will assume the evidence is relevant.
See Long,
. In arguing that it is improper to admit this evidence under Rule 403, Appellant also relies upon
Gant v. State,
. The original presiding judge orally granted the following paragraphs of Appellant’s discovery motion:
9. All medical, laboratory and scientific reports prepared in regard to the Defendant's case and/or which form the basis of the charge against the Defendant and/or which the State intends to introduce at any hearing or trial;
[[Image here]]
11. All medical records pertaining to the treatment of any witness for injuries or trauma allegedly resulting from the acts or omissions of the Defendant, including any video and/or audio recordings made of any witness or complainant in this case as part of said witness’ or complainant’s treatment.
. Although the original brief purportedly contains twelve points of error, there are only eleven points of error which apply to the instant case. Consequently, this point of error is renumbered as Point of Error Eleven. Two additional points of error were raised in a supplemental brief and are numbered Points of Error Thirteen and Fourteen. These supplemental points have been renumbered as Points of Error Twelve and Thirteen.
