The attention necessary to detect target digits in prose passages of equal length was varied by partially masking the passages with varying intensities of white noise. The subjects assessed the duration of the passages by use of a magnitude estimation scale, without reference to clock time. It was found that those passages requiring more attention for analysis were judged to be of greater duration than those requiring less attention. Ornstein's cognitive theory of the perception of duration is… 

Attention and the Perception of Duration during Encoding and Retrieval

Separate groups of subjects spent 50 s encoding a list of nonsense syllables, or a list of unrelated words, or a list of related words, and then 50 s attempting to recall them. On a subsequent

Investigation of whether the filled interval effect is influenced by different attentional perspectives of the same event indicated that a given pair of melodies could produce over- or underestimations, depending on which hierarchical level of structure was selectively tracked.

Attentional processes in time perception: effects of mental workload and event structure.

The results point to the central role of attention in temporal experience, as increases in workload and the degradation of structure led to inaccurate reproductions.

Duration Differences: Attentional Demand or Time Error?

Underwood (1975) has used judgments of duration to compare the attentional demands of learning and recall. His study is critically discussed and two further experiments are reported. In experiment 1

Duration Illusions in a Train of Visual Stimuli

The first stimulus in a sequential train of identical flashes of light appears to last longer than those in the middle of the train, and the mechanisms activated are peculiar to the visual system, since no similar illusion of duration was consistently experienced with a train of auditory tones.

Results showed that in contrast to irregularly timed events, those filled with regularly timed or continuous pitch information yielded high levels of accuracy that increased with greater learning experience, and durations marked by a nonarbitrary ending were more accurately remembered than those marked by an arbitrary ending.

Directed attention prolongs the perceived duration of a brief stimulus

The results of all six experiments support the assumption that directed attention prolongs the perceived duration of a stimulus.

Time perception and attention: The effects of prospective versus retrospective paradigms and task demands on perceived duration

The results are consistent with an attentional allocation model, and they suggest that nontemporal task demands disrupt or interfere with timing in both prospective and retrospective situations.

Remembered duration: Effects of event and sequence complexity

Two experiments investigated the remembered duration of relatively long intervals. In both, subjects viewed two sequences of visual patterns. Then they unexpectedly were asked to make a comparative

Attention and Interference in Prospective and Retrospective Timing

The results showed a trade-off between temporal and nontemporal task performance: prospective-timing groups were more accurate in judging time and were worse at proofreading, whereas retrospective-timed groups were relatively poor at judging time but better atProofreading.

Effect of Loud Noise on Attentional Selectivity

The effects of loud noise are examined by observing its influence upon a combined tracking and multi-source monitoring task, which improves in noise, as does the detection of centrally located signals in the monitoring task.

Selective Attention: Perception or Response?

A relative lack of response competition was found, which might be due to successive organization of the two responses at different stages in the perceptual sequence, and the results clearly showed that the main limit is perceptual.

Shadowing and Monitoring for Selective Attention

Although shadowing has been assumed to hold attention strongly (e.g. Hochberg, 1970) this has not been demonstrated, and the incidence of errors and intrusions suggest that it is not as powerful a
