Effects of event structure on retrospective duration judgments

Two experiments examined whether varying degrees of event coherence influence the remembering of an event’s actual duration. Relying on musical compositions (Experiment 1) or filmed narratives (Experiment 2) as experimental stimuli, the underlying hierarchy of information within events (i.e., melodic intervals or story elements) was either attentionally highlighted or obscured by placing a varying number of accents (i.e., prolonged notes or commercial breaks) at locations that either coincided or conflicted with grammatical phrase boundaries. When subjects were unexpectedly asked to judge the actual duration of events, through a reproduction (Experiment 1) or verbal estimation (Experiment 2) task, duration estimates became more accurate and less variable when the pattern of accentuation increasingly outlined the events’ nested relationships. Conversely, when the events’ organization was increasingly obscured through accentuation, time judgments not only became less accurate and more variable, but were consistently overestimated. These findings support a theoretical framework emphasizing the effects of event structure on attending and remembering activities.     

Prospective and retrospective duration judgments: A meta-analytic review

A meta-analytic review compared prospective and retrospective judgments of duration, or duration judgment paradigm. Some theorists have concluded that the two paradigms involve similar cognitive processes, whereas others have found that they involve different processes. A review of 20 experiments revealed that prospective judgments are longer and less variable than are retrospective judgments. Several theoretically important variables moderate these effects, especially those concerned with information processing activities. Therefore, somewhat different cognitive processes subserve experienced and remembered duration. Attentional models are needed to explain prospective judgments, and memory-based models are needed to explain retrospective judgments. These findings clarify models of human duration judgment and suggest directions for future research. Evidence on duration judgments may also influence models of attention and memory.     

Relative and absolute duration judgments under prospective and retrospective paradigms

A dual-process contingency model of short duration judgment is proposed and tested. The first process, or P(t), is a timer that uses cognitive capacity to keep track of units of time. If capacity is directed toward other tasks, P(t) will record fewer units and produce lower time judgments than when capacity is not directed toward other tasks. This timing process is most likely to affect performance when people know in advance (prospective judgments) that time judgments will be required and when absolute, rather than relative, judgments are made. The second process, or P(m), which is used for retrospective and relative judgments, judges duration on the basis of the number of remembered high priority events (HPEs) occurring during the interval. When this process is used, time judgments increase with the amount of HPEs that can be retrieved at the moment of judgment. Two experiments are reported. Tactual stimuli were presented, and nontemporal information processing load (simple or complex stimuli), type of judgment (absolute or relative), and judgment paradigm (prospective or retrospective)were manipulated. The results obtained support the proposed dual-process contingency model.     

The role of a change heuristic in judgments of sound duration

The present study investigated whether the quality of a frequency change within a sound (i.e., smooth vs. abrupt) would influence perception of its duration. In three experiments, participants were presented with two consecutive sounds on each of a series of trials, and their task was to judge whether the second sound was longer or shorter in duration than the first. In Experiment 1, participants were more likely to judge sounds consisting of a smooth and continuous change in frequency as longer in duration than sounds that maintained a constant frequency. In Experiment 2, the same bias was observed for sounds incorporating an abrupt change in frequency, but only when the frequency change was relatively small. The results of Experiment 3 suggested that the application of a change heuristic when generating duration judgments depends on the perception of change as originating from a single, integrated perceptual object.     

Prospective and retrospective judgments of time as a function of amount of information processed.

The subjects, 120 college students, sorted cards for 42 sec with instructions to process 0, 1, or 2 bits of information per card (response uncertainty) and then were asked to make an absolute judgement of the interval's duration. Half of the subjects knew this judgement would be required before the interval (prospective paradigm); half did not (retrospective paradigm). Judged time was an inverse linear function of response uncertainty under the prospective paradigm, whereas no significant function was obtained under the retrospective paradigm.     

Sex differences in duration judgments: A meta-analytic review

We quantitatively reviewed human sex differences in the magnitude and variability of duration judgments. Data from 4,794 females and 4,688 males yielded 87 effect size estimates of magnitude and 28 of variability. The overall sex difference in duration judgment magnitude was small but statistically significant. It was moderated by whether study participants knew in advance (prospective paradigm) or only later (retrospective paradigm) that they would be required to judge duration. Although prospective judgments showed no overall sex effect, some levels of moderator variables showed a small but statistically significant effect. Retrospective judgments showed a larger subjective-to-objective duration ratio for females than for males, and several variables moderated this effect. Females' judgments also showed more intersubject variability than did males' judgments. Relative to males, females sustain attention to time more in the prospective paradigm and have better episodic memory in the retrospective paradigm.     

Reminding as a basis for temporal judgments

In the normal course of events, some events bring to mind earlier events. This reminding or, in the context of list learning experiments, study-phase retrieval can serve as a basis for the accurate judgment of the relative recencies of the two events in question. In this article, evidence for this position is presented in three experiments. By manipulations of encoding using visual imagery instructions and word associations, appropriate conditions were arranged for reminding to occur. The results of all three studies support the position that reminding provides a direct basis for later judgments of the relative recency of events.     

Maximizing,choice freedom,and duration judgments in choice making

This paper examines (a) whether people are less accurate in judging choice time as choice tasks involve more choice options, more choice information, or a combination of both and (b) whether people with a higher tendency to look for the best option in choice making (maximizers) have less accurate duration judgments of choice time as compared to people who are more easily settling for a choice outcome that is satisfactory (satisficers). A multilevel analysis is used to explore the relationships of interest using data collected through a series of choice tasks. In general, the results suggest that people seem to misjudge time durations when making choices. Moreover, empirical evidence demonstrates that people with an outspoken tendency to maximize in choice making do not differ significantly in estimating choice time accurately as compared to people who experience almost no need to maximize.     

Counting eliminates the repetition effect in judgments of temporal duration.

College student subjects estimated the duration of time intervals (8–54 sec) by counting or not (N=35 per group). Counting eliminated the repetition effect (a decline in the magnitude of estimations across trials), and resulted in a truncation of the psychophysical function. The former result was interpreted as contrary to Treisman's (1963) model. The latter result was attributed to the effortfulness of counting, which was established in a subsequent experiment.     

Domain familiarity as a cue for judgments of learning

Students differ in how much they already know about topics within and across their courses. Few studies, however, have examined the relationship between participants’ levels of knowledge across topics (i.e., their “domain familiarity”) and their learning of information from those topics, their study choices related to those topics, and their subjective self-assessments of their learning about the topics. As such, in two studies we had participants (Study 1, college students; Study 2, Mturk workers) rank their domain familiarity for several to-be-studied domains (e.g., chemistry, history), rate their efficacy and interest in those domains, study and make judgments of learning (JOLs) for facts from each domain, and finally complete a short-answer test over those facts. Participants’ efficacy and interest ratings for the topics were linearly related to their topic rankings, as were their recall of and JOLs for facts from those domains. Although the JOLs were consistently overconfident, they were more overconfident for better-known than for lesser-known topics. Participants’ study times were not related to their topic rankings (Studies 1 and 2), but participants did use domain familiarity to strategically decide which domains to restudy before the test (Study 2). Participants typically chose to restudy their least-familiar topics, but chose to restudy their best-known topic under extremely limited restudy conditions. As a whole, the results suggest that participants effectively use their domain familiarity as a basis for their JOLs and restudy choices, but to some extent overuse this factor to assess their learning, and underuse it to guide initial study.     

Inference-based retrospective revaluation in human causal judgments requires knowledge of within-compound relationships

In an allergist causal-judgment task, food compounds were followed by an allergic reaction (e.g., AB+), and then 1 cue (A) was revalued. Experiment 1, in which participants who were instructed that whatever was true about one element of a causal compound was also true of the other, showed a reverse of the standard retrospective revaluation effect. That is, ratings of B were higher when A was causal (A+) than when A was safe (A-). This effect was taken to reflect inferential reasoning, not an associative mechanism. In Experiment 2, within-compound associations were found to be necessary to produce this inference-based revaluation. Therefore, evidence that within-compound associations are necessary for retrospective revaluation is consistent with the inferential account of causal judgments.     

The autoshaping procedure as a residual block clock

In the first experiment, 4 pigeons were each presented with a recurring sequence of four key colors followed by the delivery of grain (block clock). Once the rate of pecking had stabilized, three of the colors were replaced, during different series of sessions, by a darkening of the key. The rate of pecking was reduced within those segments of the interval between deliveries of food during which the key was dark; when the key was dark during the final portion of the interval, rates were reduced throughout the entire interval. In the second experiment, 3 new pigeons were exposed to a different sequence of colors, and the final stimulus was replaced in successive conditions by a novel color, a darkened key, and a restoration of the original color. The data indicated that darkening the key had a more severe, more extensive, and more persistent effect than did a mere change in color. These results suggest that it may be fruitful to conceptualize the autoshaping procedure as a special version of the block clock in which pecking is suppressed throughout the greater part of the interval by darkening the key. In the final condition, the same stimulus appeared in each of the last three portions of the interval. The rate of pecking was lower during the last two portions than when distinctive colors were presented, with the peak rate now appearing in the fifth of seven equal temporal components.     

Attractiveness as a biasing factor in the judgments of school psychologists

A sample of 324 practicing school psychologists received a fictitious case study to which was attached a photograph of an attractive boy, an attractive girl, an unattractive boy, or an unattractive girl. Otherwise the case studies were identical. Each psychologist was asked to make several decisions based upon the information provided in the case study. Results of a multivariate analysis of variance indicated that a pupil's attractiveness had a significant effect on the judgments of school psychologists.     

Effects of internal clock and memory disorders on duration reproductions and duration productions in patients with Parkinson's disease

Patients with Parkinson's disease (PD) exhibit deficits in perceptual and motor timing as well as impairments in memory and attentional processes that are related to dysfunction of dopaminergic systems in the basal ganglia. The aim of the present study was to assess the relationships existing between impaired duration judgments and defective memory and attention in PD patients. We compared time performance of medicated PD patients and control subjects on a duration reproduction task that is highly memory-dependent, and on a duration production task that could reveal effects of changes in the speed of internal time-keeping mechanisms. Each task was performed in a control counting condition and in a condition requiring divided attention between the temporal task and a concurrent reading task. Moreover, PD patients and control subjects were assessed on memory and attention using a battery of neuropsychological tests. The results revealed that in the concurrent reading condition of the reproduction task, duration judgments tended to be more variable in PD patients than in control subjects. Moreover, variability of duration reproductions was correlated with both measures of memory and of disease severity. In the concurrent reading condition of the production task, duration judgments were significantly shorter in PD patients than in control subjects, and accuracy of duration productions was correlated with scores on sub-tests of short-term memory. The findings suggest that the administration of dopamine did not entirely remove the memory deficits in PD patients. Moreover, DA treatment would have abnormally accelerated the rate of the internal clock leading to shorter duration productions in PD patients. The whole results indicate that dopamine administration in patients might have overshadowed the slowing rate of the internal clock usually reported in non medicated PD patients, without entirely restoring all of the memory functions.     

Personality disorders and the duration of depressive episode: a retrospective study

In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project we examined the relationship between chronicity of depression and personality disorders. Three hundred and eighty-five depressed outpatients were evaluated with semi-structured interviews. Duration of depression was analyzed as a continuous variable, and by subdividing patients by the DSM-IV (APA, 1994) chronic specifier (i.e., more or less than 2 years). Two separate regression analyses addressed the association between major depressive episode duration and each of the ten personality disorders found on Axis II. Although there was some difference between particular personality disorders associated with the two indicators of depressive duration, the results of the regression analyses indicate that the chronicity of depression is associated with personality disorders.     

The predictive value of daily vs. retrospective well-being judgments in relationship stability

The present study examined the role of daily and retrospective judgments of well-being and relationship satisfaction in relationship longevity. Participating couples completed a 14-day diary report of well-being and relationship satisfaction. After the daily diary survey, they evaluated the 14-day period. Participants also rated their global relationship satisfaction at that time. Retrospective judgments of daily well-being predicted later relationship status better than daily ratings of well-being did, whereas daily ratings of relationship domain satisfaction predicted later status better than retrospective judgments of daily relationship domain satisfaction did. Furthermore, global relationship satisfaction predicted later relationship status better than daily ratings of relationship domain satisfaction did. In general, global, summary judgments had a greater predictive value of future relationship status than did specific, daily judgments. Finally, synchronicity of daily fluctuations of well-being between partners predicted later relationship status.
