“…As predicted, interval estimates in the graphemic condition were an increasing function of list length. It is noteworthy that the increasing function obtained in the present graphemic condition is similar to the results of previous prospective studies (Buffardi, 1971;Craig, 1973;Mo, 1975;Thomas & Brown, 1974), which used nonverbal stimuli and required no active processing during the interval.…”

“…In one set of studies (Bakan, 1955; Burnside, 1971;Curton & Lordahl, 1974;DeWolfe & Duncan, 1959;Hicks & Brundige, 1974;McKay, 1977; Vroon, 1970), estimates decreased as the amount of information presented during the interval increased. The second set of studies (Aitken & Gedye, 1968; Buffardi, 1971;Craig, 1973; Mo, 1975; Thomas & Brown, 1974) produced the filled-duration illusion-intervals filled with nonverbal stimuli such as lights or tones were A summary of this paper was presented at the American Psychological Association convention, Washington, D,C., August 1982.

Undergraduate students performed one of three levels of processing on each word (15, 30, or 45) presented during a 120-sec interval. Subjects were told in advance that they would be required to estimate the length of the presentation interval (prospective condition) or were presented with an unexpected estimation task (retrospective condition). In the prospective condition, interval estimates were an inverse function of list length when relatively deep levels of processing were required, but were an increasing function of list length when shallow processing was required. In the retrospective condition, estimates were an increasing function of list length and were unaffected by different levels of processing. The interval estimation model proposed by Hicks, Miller, and Kinsboume (1976) provided a better account of the data than did the storage-size hypothesis of Omstein (1969).Interval estimation requires subjects to indicate the length of a given interval in the absence of an external timing device. Different paradigms have produced different results and have spawned opposing theories of interval estimation. When subjects have not known in advance that estimates would be required, that is, the retrospective paradigm was used, estimates increased as the amount of information presented during the interval increased (

“…Most research has focused on manipulating nominal stimulus attributes in order to effect changes in cognitive activity. Mo (1971Mo ( , 1975 found that increasing the number of dots in briefly flashed dot patterns led to an increase in their apparent duration. Buffardi (1971) reported similar findings in the visual, as well as in the auditory and tactual, modalities.…”

Bower, Barbara Sakitt, and the referees for helpful comments. employed very recently by Mo (1975) in a study of the effects of numerosity on temporal judgments.To fix ideas, suppose that a stimulus consists of a circle, which has size Al or A 2 (>A I ) , presented for a duration T I or T2 (> T d. In a block of trials, A, will have a certain frequency, Pa say (a for "area"), and A 2 a frequency 1 -Pa; and T I will have a frequency, Pt say (t for "time"), and T2 a frequency 1 -Pt. For such a block, the subject's task is either (a) to judge the duration of each stimulus immediately after it is presented on a rating scale, 0 = "short," 1 = "medium," 2 = "long," and to estimate the Al frequency at the end of the block, or (b) to judge the size of each stimulus immediately after it is presented (0 = "small," 1 = "medium," 2 = "large"), and to estimate the TI frequency at the end of the block.…”

Judgments of the apparent duration and size of visually presented circles vary directly with the duration and size of the presented stimuli. When the frequencies of stimulus duration (short vs. long) and stimulus area (small vs. large) are varied, perceived size and duration are directly related to the frequency of the lower attribute value (short or small). These data are compared to the predictions of different information-processing models. The model which accounts for the data best is one in which it is assumed that perceived size and perceived duration grow together over the course of time spent sampling size information, and that attribute frequency affects the rate of sampling and/or the point at which.sampling stops.In an attempt to explain the role of nontemporal stimulus information in the estimation of brief stimulus durations «100 msec), the suggestion has been made that estimates of duration are affected by the time spent processing nontemporal information (Avant, Lyman, & Antes, 1975;Thomas & Weaver, 1975). The validity of this suggestion has been explored in a recent study by Thomas and Cantor (1975) in which subjects were presented with solid circles varying in size (nontemporal information) and in duration, and were asked to judge the size and the duration of the stimuli. This study shows that perceived duration is directly related to stimulus size, and perceived size is directly related to stimulus duration. A model was proposed for the processing of size information, which accounts for both sets of judgments reasonably well. What these data support is not merely a processing model, but the model plus the assumption that processing time is directly related to perceived duration.Having judgments of both stimulus attributes, duration and size, allows one to investigate the effect of size on perceived duration and the dual effect of duration on perceived size. This, in turn, leads to stronger tests of the present approach than would be possible if only duration estimates were available. Further tests of the approach are possible when the range of tasks is extended and when a variety of processing models are examined. This is the tack pursued in the present study. In the Thomas and Cantor (1975) study, the subject's perception of one stimulus attribute was related to the objective values of the other attribute; for example, perceived duration was related to stimulus size. In the present study, the design allows, in addition, perceived duration to be related to perceived size of a given stimulus, as the frequencies of stimulus attributes are varied. Variation in attribute frequency has been This research was supported by Grant No. GB-43175 from the National Science Foundation to the first author. We wish to thank Gordon H.
