¶1Pursuant to General Statutes § 52-270,
¶2The record discloses that on September 25, 1990, a jury found the petitioner guilty of robbery in the first degree in violation of General Statutes § 53a-134, conspiracy to commit robbery in the first degree in violation of General Statutes §§ 53a-48 and 53a-134 and assault in the second degree in violation of General Statutes § 53a-60. The petitioner was tried jointly with two other defendants who the state claimed were coparticipants in the crimes. The other defendants are not involved in this petition.
¶3On October 12, 1989, at approximately 6:45 p.m., Timothy Wallace was assaulted and robbed by three men, two of whom were armed. The assailants took his Whalers
¶4The next day, Wallace returned to the police station to look at arrays of photographs. He was shown three eight picture arrays, each array containing a photo of one of the suspects arrested the night before. Wallace *61picked the suspects’ pictures out of the arrays and identified them as being of the men who had attacked and robbed him.
¶5Almost one year later, in September, 1990, Wallace testified at trial that he was positive of the photographic identification and that he had no doubt that these men were his assailants. There was some discrepancy in his description of the petitioner’s height and weight, but his description of the petitioner’s coloring, hair length and clothing was consistent throughout the proceedings.
¶6At his criminal trial the petitioner called five alibi witnesses: his mother, his sister, his brother, his sister-in-law, and a friend of his mother’s. They all testified that until approximately 7:30 p.m. on the night of the robbery the petitioner was with them, at the house he shared with his mother. At that time, according to this testimony, his brother and sister-in-law gave the petitioner a ride to the corner of Capen and Clark Streets, about ten blocks from the scene of the robbery. The petitioner was on his way from there to visit a friend on Elmer Street when he met Reginald Harris and Dwayne Saunders, the two men later convicted, along with the petitioner, of the robbery. The three men talked briefly and had begun walking together up the street when they were surrounded by police and arrested.
¶7*62On September 27,1990, a day after the jury returned a guilty verdict and almost one year after the robbery, the petitioner’s mother saw Wallace at a neighborhood pharmacy about one block from the crime scene.
¶8Wallace did not communicate his doubt to the petitioner’s attorney. Upon learning of Wallace’s doubt from the petitioner’s mother, the petitioner’s attorney sent an investigator to take Wallace’s statement. On September 27,1990, Wallace told the petitioner’s investigator that “[w]hen I saw [the petitioner] in court I noticed he was taller [and] heavier, and was wearing glasses. . . . I did testify that day that [the petitioner] was involved in the robbery, however, I now think I may have made a mistake in identifying him.”
¶9The next proceeding was a hearing on a motion for a new trial, held on October 12, 1990, at which time Wallace testified that he was about 40 percent sure of his identification; he could not say whether it was or was not the petitioner.
¶10We first address the threshold issue of whether the trial court applied the proper standard in denying the petition for a new trial. Citing Pradlik v. State, 131 Conn. 682, 687, 41 A.2d 906 (1945), and Asherman v. State, 202 Conn. 429, 434, 521 A.2d 578 (1987), the petitioner argues that there is a split of authority in Connecticut regarding the proper standard governing the granting of a petition for a new trial based on newly discovered evidence. We do not agree.
¶11Connecticut has long recognized petitions for new trials based on newly discovered evidence. Lester v. State, 11 Conn. 415, 418 (1836); Gallup v. Fish, 2 Root (Conn.) 452 (1796); Ainsworth v. Sessions, 1 Root (Conn.) 175 (1790); Foster v. Hough, 1 Root (Conn.) 173 (1790). The modern standard, or an equivalent formulation, adopted by a majority of state and federal courts for granting such a petition
¶12Connecticut cases have employed this standard, which we will refer to as the Ashermanstandard, in several different contexts involving newly discovered evidence. Lombardo v. State, 172 Conn. 385, 389, 374 A.2d 1065 (1977) (new testimony of two witnesses, one of whom did not testify at trial and one of whom invoked fifth amendment at trial); Taborsky v. State, supra, 142 Conn. 624-25 (new evidence of mental disease); Krooner v. State, 137 Conn. 58, 66, 75 A.2d 51 (1950) (evidence by friends, doctors and fellow shipmates that defendant was drunk or mentally ill at time of murders); Link v. State, 114 Conn. 102, 157 A. 867 (1932) (newly discovered witness). The petitioner does not cite, nor does our research reveal, any Connecticut case employing the Ashermanstandard in a petition for a new trial based solely on a claim of false testimony, i.e., recantation.
¶13A standard specifically addressing the issue of false testimony was enunciated in Larrison v. United States, 24 F.2d 82 (7th Cir. 1928). False testimony may be of two types: (1) where a material witness admits to per*65juring himself at trial
¶14Under the first prong of the Pradlikstandard, a petition for a new trial based on a recantation should be granted only if the judge is convinced that the original testimony at trial was false. This, of course, requires the judge to examine the circumstances surrounding *66the recantation in order to determine whether it is credible. For example, in Smith v. State, supra, 139 Conn. 249, the Supreme Court affirmed the trial court’s denial of a petition for a new trial based on a witness’ recantation. A portion of the evidence adduced at the criminal trial centered on three witnesses who claimed that the petitioner drove a car similar to that used during the murder several days earlier. Id. One of those witnesses recanted her testimony at a deposition in Alabama while serving a prison sentence. Employing the Pradlikstandard, the trial court found that the recantation was not credible and denied the petition. The Supreme Court affirmed the trial court’s decision under an abuse of discretion standard. Id., 253.
¶15Similarly, in State v. Davis, supra,2 Conn. Cir. Ct. 257, the Appellate Division of the Circuit Court applied the Pradlikstandard to a witness’ recantation, stating that it was the trial court’s function to compare the character, weight and credibility of the witness’ recantation to that of the witness’ testimony at trial in order to determine whether a new trial was warranted. Id., 262.
¶16A recent application of the credibility assessment under the Pradlikstandard can be found in this court’s decision in Talton v. Warden, 33 Conn. App. 171, 179, 634 A.2d 912, cert. granted on other grounds, 228 Conn. 919, 636 A.2d 850 (1994), a case, like the present one, involving a victim’s recantation.
¶17Despite the petitioner’s assertion to the contrary, our research reveals no split in authority in Connecticut concerning the applicable standard for a petition for a new trial. Rather, there are two standards applicable to petitions for new trials based on newly discovered evidence — one for false testimony and one for all other evidence. In this case, the trial court assumed, without deciding, that the victim’s recantation constituted newly discovered evidence and thereafter limited its analysis to the fourth prong of the Ashermanstandard, namely, whether the recantation would likely produce a different result at trial. In doing so, the trial court assessed the credibility of the recantation and thereafter denied the petition.
¶18The petitioner argues that the trial court properly applied the Ashermanstandard but in doing so, improperly assessed the credibility of the recanted testimony. He contends that the trial court was limited under the Ashermanstandard to an assessment of the impact the recantation testimony would have on a jury on retrial. Despite the legion of cases holding that a petition for new trial is addressed to the sound discretion of the trial court; Gillis v. Gillis, 214 Conn. 336, 340, 572 A.2d 323 (1990); Bernier v. National Fence Co., 176 Conn. *68622, 628, 410 A.2d 1007 (1979); E.M. Loew’s Enterprises, Inc. v. Surabian, 146 Conn. 608, 610, 153 A.2d 463 (1959); the petitioner asks us to establish a rule of law that, when a defendant has been convicted solely on the basis of a witness who later recants, a petition for a new trial must automatically be granted under Asherman. Although the petitioner fails to cite any Connecticut cases holding that the trial court should be deprived of the time honored jurisdiction over the witnesses’ credibility in a petition for a new trial, the petitioner apparently feels that under the present circumstances a hearing serves no purpose and that the petitioner should have a new trial on demand.
¶19In the alternative, the petitioner argues that should the Pradlikstandard apply, the trial court failed under that test to make a proper credibility determination. We agree with that portion of the petitioner’s alternative argument that the trial court should have applied the Pradlikstandard to the victim’s recanted testimony. We conclude, however, that the trial court properly applied that standard, albeit mistakenly, in its analysis of the fourth prong of the Ashermanstandard. In essence, the trial court’s analysis under the fourth prong of the Ashermanstandard encompassed the credibility determination mandated by the first prong under Pradlik.
¶20Recantation as grounds for a new trial has always been viewed with skepticism. Well over one hundred years ago, our Supreme Court enunciated this skepticism in Shields v. State, 45 Conn. 266, 270 (1877) as follows: “After the trial is over and the accused stands convicted, with the heavy penalty of the law impending and just ready to fall upon him, how easy by artful or even honest suggestion to awaken a sympathy even in the heart of the victim, who was the main, perhaps only witness against the accused, and who naturally feels responsible for the conviction; and how easy for such witness by a process of speculation, colored by feeling, to feel and express a doubt about the correctness of the opinion entertained at the time of the transaction.” See also Ainsworth v. Sessions, supra, 1 Root (Conn.) 176; 58 Am. Jur. 2d, New Trial § 440 (1989).
¶21The trial court in this case described the victim’s recantation as “something akin to buyer’s remorse,” a characterization on which the petitioner’s argument that the trial court abused its discretion principally relies. The term “buyer’s remorse” is merely shorthand for the situation described in Shields v. State, supra, 45 Conn. 270, to wit, after the fact self-doubt brought on by the realization that one’s testimony has put another behind bars. The terms “buyer’s remorse” serves to distinguish this sort of recantation from that where the recanter admits to knowingly perjuring himself at trial and now allegedly wants to “come clean.”
¶22*70In this case, Wallace’s recantation is of the former type. He never claimed that he lied when he identified the petitioner in the photo array. On the contrary, he was absolutely sure of his identification. Later, he says that he began having doubts at trial and stated at the hearing on the petition for a new trial that he could not identify the petitioner as the person who robbed him. The trial court noted this by stating “[wjhat began as an unexpressed doubt [at trial], graduated to the possibility of a mistake [upon seeing the petitioner’s mother after trial and] became a certainty of error in identification [at the hearing for a new trial].”
¶23The seeds of doubt in Wallace’s mind were apparently not planted until almost one year after the robbery when, after having just finished testifying at the petitioner’s trial, he met the petitioner’s mother in the local pharmacy. During their conversation, the petitioner’s mother told Wallace who she was, said that her son was found guilty, and asked if he was sure it was her son who robbed him. It was only then that Wallace expressed’doubt about his prior identification, telling the petitioner’s mother that when he saw the petitioner at trial he looked bigger than he remembered and that he also was wearing glasses at the time of the robbery. Although Wallace testified at trial that the petitioner looked bigger than before, he did not communicate any doubt regarding his prior identification or his in-court identification of the petitioner during the trial. By the time of the hearing on the petition for a new trial, however, Wallace testified that he now had ho doubt that the petitioner was not involved in the robbery. This is a classic case of a Shieldssituation, an erosion of the victim’s confidence in his own memory.
¶24The petitioner complains that the trial court made a credibility determination without delineating any objective reasons for not believing the recantation. We *71do not agree. In a memorandum of decision, the trial court found, inter alia, that (1) the victim’s recantation came about only after a conversation between the petitioner’s mother and the victim, (2) the victim conceded that his memory had diminished over time and was better at the time of his initial identification of the petitioner than at the time of the hearing on the petition for a new trial, and (3) the victim never recanted his identification of the petitioner’s photograph. We note, as the trial court did, that his recantation was limited to the petitioner’s height and weight and not his facial features. Significantly, the petitioner had gained a considerable amount of weight since the time of his arrest — from 238 pounds at the time of the crime to 283 pounds at the hearing on this petition. At his criminal trial, the petitioner had gained only five to ten pounds from the date of the crime. Moreover, the trial court found that Wallace had demonstrated under questioning during trial a difficulty in gauging the height of people present in the courtroom, casting doubt on whether his present uncertainty over the height and weight of the petitioner was believable.
¶25The trial court also characterized Wallace’s testimony as having been influenced by the meeting with the petitioner’s mother and the sympathy associated with realizing that his identification resulted in a man’s going to prison. Finally, the trial court was aware of the petitioner’s extensive record
¶26Despite the foregoing analysis provided by the trial court regarding the credibility of the recantation, we note that nowhere in the memorandum of decision did the trial court explicitly state that it did not believe Wallace. Even if we assume for the sake of argument that the trial court did not adequately set forth the reasons it found the recantation incredible, the petitioner did not file a motion for articulation asking the trial court to enunciate the reasons why the court felt the recantation unworthy of belief. The petitioner argues that such a motion would have been pointless because all of the facts were in the record. We point out that Practice Book § 4059
¶27If the petitioner complains that the trial court did not include in its memorandum of decision the reasons why it did not find the recantation credible, his first recourse was to ask the trial court, by way of a motion for articulation, why it so concluded. There may have been objective reasons, in addition to the ones cited, that the trial court could have furnished that would have assisted the petitioner in his obligation to furnish a proper record on appeal.
¶28On the other hand, the trial court’s reasons for disbelieving the recanter may have been based, in part, on those myriad of tiny signals, such as tone of voice, *73manner of breathing, gesticulations, nervousness and the like that traditionally are used by triers of fact in assessing a witness’ credibility. A motion for articulation would not have helped the petitioner in this aspect nor are we prepared to require a trial judge to attempt to articulate such reaction to a witness.
¶29The judgment is affirmed.
¶30In this opinion the other judges concurred.
¶31 General Statutes § 52-270 (a) provides in relevant part: “The superior court may grant a new trial of any action that may come before it, for . . . the discovery of new evidence . . . .”
¶32 “The Whalers are a professional hockey team from Hartford.” State v. Harris, 28 Conn. App. 474, 476 n.1, 612 A.2d 123, cert. denied, 223 Conn. 926, 614 A.2d 828 (1992).
¶33 Immediately after the robbery, Wallace described the robber later identified as the petitioner as five feet eight inches and 180 pounds. The next day, Wallace described him as five feet six inches with a medium build. At trial, Wallace said he remembered the man being five feet ten inches. The petitioner never stood up at trial. The petitioner’s mother testified at trial that the petitioner was six feet and 225 pounds at the time of the robbery. At one point Wallace testified that he himself was six feet or six feet one inch. At the hearing on the petition for a new trial, Wallace and the petitioner stood together, and the court noted that the petitioner was one and one-half inches to three inches shorter than Wallace.
¶34 The petitioner and his mother live four or five blocks from where the crime took place. Wallace lived three or four blocks from the crime scene at the time of the robbery. He has since moved to New York City, but his family remains in the neighborhood.
¶35 The trial court did not rule on the motion for a new trial because it was based on a claim of newly discovered evidence and thus could be the subject only of a petition for a new trial brought in accordance with General Statutes § 52-570 and Practice Book § 904.
¶36 See 58 Am. Jur. 2d, New Trial § 415 (1989).
¶37 One case employing the Ashermanstandard, State v. Edwards, 10 Conn. App. 503, 524 A.2d 648, cert. denied, 204 Conn. 808, 528 A.2d 1155 (1987), involved a claim made by the defendant’s sister that the complainant’s son had recanted his testimony. The son denied such a recantation. We, however, do not consider such disputed testimony a recantation.
¶38 We note, however, that a conviction obtained by the prosecution’s “knowing use of peijured testimony is fundamentally unfair, and must be set aside if there is any reasonable likelihood that the false testimony could have affected the judgment of the jury.” (Emphasis added.) United States v. Agurs, 427 U.S. 97, 103, 96 S. Ct. 2392, 49 L. Ed. 2d 342 (1976).
¶39 There has been some dispute as to the applicable standard of proof under this standard, i.e., whether a new jury “might,” or “would probably,” have reached a different result. See United States v. Stofsky, 527 F.2d 237, 245 (2d Cir. 1975). The petitioner neither raises the question nor seeks to apply the former standard, which has been considered by some to be more “lenient.” Id.; see generally comment, “Rethinking the Standard for New Trial Motions Based Upon Recantations as Newly Discovered Evidence,” 144 U. Pa. L. Rev. 1433 (1986). Because our disposition of this appeal does not require us to resolve this issue, we do not address it.
¶40 We note that the recantation testimony in Taitón was in the context of a habeas corpus proceeding and not a petition for a new trial.
¶41 The Supreme Court granted certification in Talton v. Warden, 228 Conn. 919, 636 A.2d 850 (1994). The first two questions certified demonstrate that the determination of credibility was a proper consideration for *67the trial court and did not have to be reserved for the jury at retrial. The first two certified questions are: (1) “Did the Appellate Court correctly conclude that, based on the record of the habeas proceeding, the habeas court properly determined that the recantation testimony of the victim-witness was not credible?” and (2) “If the recantation testimony of the victim-witness was credible, did the Appellate Court properly decline to find that the appellant’s due process rights were violated?” Id. The third certified question is not relevant to our discussion.
¶42 We need not address the issue of exactly what kind of credibility assessment may be proper under the fourth prong of the Ashermanstandard. We note that a credibility type analysis has been applied under Ashermanin certain factual circumstances; Lombardo v. State, supra, 172 Conn. 391 (under Asherman, trial court not persuaded that new witness’ exculpatory testimony credible enough to persuade jury). Such analysis is consistent with the principle that a petition for a new trial is addressed to the sound discretion of the trial court. Ridolfi v. Ridolfi, 178 Conn. 377, 379, 423 A.2d 85 (1979).
¶43Notwithstanding, the petitioner cites to a myriad of cases from other jurisdictions for the proposition that a trial court is limited under the Ashermanstandard, or its equivalent formulation, to an assessment of the impact the new evidence will have at a new trial. One such case, however, State *69v. Prudholm, 446 So. 2d 729, 737 (La. 1984), appears explicitly to endorse a credibility type analysis. In affirming the trial judge’s denial of the defendant’s petition for a new trial, the Louisiana Supreme Court stated that “[w]e agree with the trial judge that [the witness] would not have been a credible witness and that the repudiation of his testimony would not have been persuasive before a new jury.” Id.
¶44 The petitioner admitted the following convictions: conspiracy to commit first degree robbery in 1987, third degree robbery in 1988, possession of narcotics in 1988, second degree larceny of a motor vehicle in 1989, the 1990 conviction that is the subject of this petition and a subsequent conspiracy to commit first degree robbery also in 1990.
¶45 Practice Book § 4059 provides in relevant part: “[Wjhen rendering judgments in trials to the court . . . the court shall, either orally or in writing, state its decision on the issues in the case and, if there are factual issues, the factual basis of its decision. The court shall include in its decision its conclusion as to each claim of law raised by the parties. . . .”
