PER CURIAM.
       Thomas M. Smalley appeals the district court’s1 order affirming the denial of
disability insurance benefits and supplemental security income. Upon de novo review,
see Perks v. Astrue, 687 F.3d 1086, 1091 (8th Cir. 2012), we agree with the district
court that the administrative law judge’s (ALJ’s) decision is supported by substantial
evidence on the record as a whole. Specifically, we find that the ALJ’s adverse
credibility determination is entitled to deference, see Finch v. Astrue, 547 F.3d 933,
935-36 (8th Cir. 2008) (credibility findings are for ALJ in first instance, and when
ALJ explicitly discredits claimant and gives good reasons for doing so, her judgment
is entitled to deference); that reversal is not warranted based on the ALJ’s alleged
failure to develop the record on residual functional capacity, cf. Ellis v. Barnhart, 392
F.3d 988, 994 (8th Cir. 2005) (reversing for failure to develop record is warranted
when such failure is prejudicial or unfair); and that Smalley has offered no basis for
remanding under sentence six of 42 U.S.C. § 405(g), see Krogmeier v. Barnhart, 294
F.3d 1019, 1024-25 (8th Cir. 2002) (discussing requirements). The district court is
affirmed. See 8th Cir. R. 47B.
