PER CURIAM.
Jarvis Demond Hemphill appeals his convictions and 141-month sentence imposed following his guilty plea to Hobbs Act robbery, in violation of 18 U.S.C. § 1951 (2012); brandishing a firearm during and in relation to a crime of violence, in violation of 18 U.S.C. § 924(c) (2012); and possessing a firearm as a convicted felon, in violation of 18 U.S.C. § 922(g)(1) (2012). On appeal, Hemphill raises several issues related to his competency to enter a guilty plea. For the reasons that follow, we affirm.
Hemphill first asserts that the Government committed prosecutorial misconduct in failing to request a competency hearing prior to his guilty plea, and the trial court erred in failing to hold such a hearing sua sponte. Because Hemphill did not request a competency hearing in the district court or otherwise challenge the court's failure to hold one, we review this issue for plain error.
During the pendency of a defendant's prosecution, the district court may grant a motion by the Government or defense counsel for a competency hearing, or may sua sponte order such a hearing, "if there is reasonable cause to believe that the defendant may presently be suffering from a mental disease or defect rendering him mentally incompetent to the extent that he is unable to understand the nature and consequences of the proceedings against him or to assist properly in his defense." 18 U.S.C. § 4241(a) (2012). To determine whether reasonable cause for a competency hearing exists, the court should consider such factors as "(1) any history of irrational behavior; (2) the defendant's demeanor at and prior to [court proceedings]; and (2) prior medical opinions on competency."
Hemphill's demeanor during the plea hearing generally demonstrated his comprehension of the proceedings and his ability to communicate effectively with his counsel. While Hemphill's history of mental health challenges was addressed at sentencing, nothing in the record suggests that these difficulties affected his ability to understand the court proceedings or to assist in his defense. Thus, we find no plain error in the district court's or Government's refusal to further inquire into Hemphill's competency.
Hemphill also asserts that he suffered constitutionally ineffective assistance of counsel based on his trial counsel's failure to move for a competency hearing. Unless an attorney's ineffectiveness conclusively appears on the face of the record, ineffective assistance claims generally are not addressed on direct appeal.
Accordingly, we affirm the district court's judgment. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
