¶ 1 A jury fоund Robert Joseph Wright guilty of theft of means of transportation, and the trial court suspended the imposition of sentence and placed him on a three-year term of probation. On appeal, he asserts the trial court improperly precluded the testimony of his psyсhiatric expert witness offered to rebut the mental state element of the offense. For the following reasons, we affirm.
FACTS AND PROCEDURAL BACKGROUND
¶ 2 We view the evidence and all reasonable inferences therefrom in the light most favorable to upholding Wright’s conviction.
See State v. Carlos,
¶3 Sergeant Gary Chatham gave Wright Miranda 1 warnings and, after Wright waived his rights, questioned him about how he came to be in possession of the vehicle. Wright told Chatham that someone named Hector had approached and offered to pay him $300 to drive the vehicle to Mexico. After Chatham asked him whether he knew the truck was stolen, Wright stated, “[Y]eah, I thought it could be stolen.” Deputy Atwell then drove Wright to Tucson in his patrol car. At trial, Atwell testified that he and Wright had discussed the circumstances surrounding Wright’s possession of the truck during the drivе to Tucson. During that discussion, Wright stated he did not think it was stolen.
¶ 4 A grand jury indicted Wright on one count each of theft of means of transportation, burglary in the third degree, and possession of burglary tools. Wright’s first trial ended in a mistrial when a defense witness improperly testified that Wright had suffered brain damage at birth. At his second trial, Wright again sought to introduce expert testimony that had been precluded at the first trial that his “mental capacity was lowered and that he is a naive-type of person.” The trial court found that the first trial judge had properly rejected the testimony as an attempt to raise an improper diminished capacity defense, and that ruling was the law of the ease. Wright moved for a judgment of acquittal after the state rested its case and again at the end of trial. The court initially denied the motion, but granted Wright’s renewed motion on the burglary charge. The jury found Wright guilty of theft of means of transportation and not guilty of possession of burglary tools. The trial court suspended the imposition of sentence and placed him on probation for three years. This appeal followed. We have jurisdiction pursuant to A.R.S. § 12-120.21(A)(1).
STANDARD OF REVIEW
¶ 5 On appeаl, Wright asserts that the trial court’s exclusion of his expert’s testimony violated his due process rights under the Fourteenth Amendment to the United States Constitution and constitutes reversible error. Generally, we review a trial court’s determination on the admissibility of expert testimony for an abuse of discretion.
State v. Moran,
DISCUSSION
¶6 Wright argues, as the sole basis for challenging his conviction, the trial court erroneously excluded expert testimony that he did not have the mental state necеssary to commit the offense. A person commits theft of means of transportation, inter alia, by knowingly controlling another person’s means of transportation “with the intent to permanently deprive the person of the means of transportation” or by “knowing or having reason tо know that the property is stolen.” A.R.S. § 13-1814(A)(1) and (5). To rebut the mens rea or mental state element of the offense, Wright attempted to introduce psy
chiatric
¶ 7 Wright asked the trial court to reconsidеr the ruling in the first trial precluding the expert testimony and to allow him “to proceed with a diminished capacity defense.” In support of the motion, Wright stated the expert would testify about the “numerous mental deficiencies he diagnosed after evaluating Mr. Wright. These deficiencies inсluded Mr. Wright’s low IQ, his deficient test results including but not limited to his common sense, difficulties with detail and his child-like aspirations for the future.” Wright acknowledged the testimony had been precluded pursuant to
State v. Mott,
¶ 8 In the alternative, Wright argued the proposed testimony was admissible to help the jury determine whether he formed the requisite mental state “at the time of the offense.” He distinguished his ease from Mott, arguing that “[i]n the Mott case the еxpert was going to testify that the defendant could never form the prerequisite intent. In this case our expert was going to testify that [Wright’s] mental capacity was lowered and that he is a naive-type of person.” The state argued the first trial judge had “already ruled in favor of the Statе regarding the requested testimony,” and that ruling was “the law of the case.” The state also characterized the proposed testimony as supporting “a diminished capacity defense which is expressly prohibited under Arizona law.” The trial court agreed and precluded the tеstimony.
¶ 9 As a preliminary matter, “[t]he courts of this state are bound by the decisions of [the Arizona Supreme Court] and do not have the authority to modify or disregard [its] rulings.”
State v. Smyers,
¶ 10 In
Mott,
our supreme court rejected the diminished capacity defense and held testimony of a mental health professiоnal about a defendant’s mental incapacity owing to a mental disease or defect is only admissible in the context of an insanity defense.
¶ 11 Wright relies on
Clark,
which was decided while this appeal was pending.

In
Clark,
the Court considered the three different categories of evidence “with a potential bearing” on the mental state element of an offense: observation, mental disease, and mental capacity. — U.S. at -,
¶ 12 In sum, the Court in
Clark
held
Mott
does not violate the Fourteenth Amendment guarantee of due рrocess in restricting mental disease and mental capacity evidence to an insanity defense and in precluding such evidence when offered to challenge the mens rea element. - U.S. at -, -,
¶ 13 Wright now argues that his expert’s proposed testimony was observation evidence and was improperly excluded by the trial court. The state argues Wright has waived all but fundamental error reviеw because this theory was not argued to the trial court. Based on our review of the record, we agree that Wright generally challenged the Mott rule rejecting the diminished capacity defense, but did not argue below that the trial court had improperly precluded the type оf observation evidence admissible under Mott 4
¶ 14 Because Wright failed to raise this ground below, he has “forfeited] the right to obtain appellate relief unless [he] prove[s] that fundamental error occurred.”
State v. Martinez,
¶ 15 We therefore must determine whether the proposed testimony of Wright’s expert falls into the category of observation evidence, which may be admitted short of an insanity defense to rebut the mens rea element, or capacity evidence, which may not. Observation evidence includes evidence of a defendant’s behavior, statements, and expressions of belief around the time of the offense.
Clark,
— U.S. at -,
¶ 16 In this case, the state was required to prove that Wright had controlled another person’s means of transportation either “knowing or having reason to know that the property [was] stolen” or “with the intent to permanently deprive the person of the means of transportation.” § 13-1814(A)(1) and (5). Wright’s offer of proof bearing on the issue of his mental state consisted of his expert’s repоrt, which stated that, in the expert’s opinion, Wright had borderline to low average intelligence and suffered from attention-deficit/hyperactivity disorder, a learning disorder, and an anxiety disorder. His offer of proof did not connect any of these diagnoses to whether or not Wright knew or should have known the vehicle was stolen or intended to permanently deprive the victim of the vehicle. Therefore, Wright failed to link the evidence to the behavioral characteristics relevant to the required mental state.
¶ 17 Admissible observation evidence bears оn a defendant’s state of mind at the time a crime was committed, “as distinct from professional mental-disease or capacity evidence going to ability to form a certain state of mind during a period that includes the time of the offense charged.”
Clark,

¶ 18 We affirm.
Notes
.
Miranda v. Arizona,
. We note Wright did not argue below that the testimony was admissible as character trait evidence under Christensen. Therefore, we decline to address the testimony’s admissibility on that basis.
. Even though the trial court did not have the benefit of
Clark v. Arizona,
- U.S. -,
.
Clark
did not announce a new rule, and although the labels the Court used to describe categories of evidence may be new, the categories themselves are not. Wright’s argument below was confined to a direсt challenge to
State v. Mott,
. Having made this determination, we need not consider the state’s additional implicit argument that the testimony of Wright’s expert about his subjective mental state was irrelevant in any event because he could also have been found guilty under the statute’s objective standard.
