“…Pöppel (1970) studied choice reaction times for both visual and auditory stimuli and found multimodal distributions of response times with a period of 30 ms. The method of that study and others has been criticised (Vorberg & Schwartz, 1987;Vroon, 1970Vroon, , 1974. Vorberg and Schwartz (1987) demonstrated that an appearance of regular oscillations can occur in data distributions by chance and there is no clear evidence that the distributions obtained by Pöppel (1970) were not chance phenomena.…”

“…At 6 deg s -1 there were 462 data points that were collected in bins of 10 ms, but the temporal resolution of the measure of response latency was 3 ms, so it is not clear why a bin size of 10 ms was chosen. Vroon (1970) showed that peaks occur at different places depending on bin size, even for the same set of data, and the simulation run by Vroon (1974) shows that 462 data points is far too few for meaningful results to be obtained. In short, there are too many degrees of freedom in the data analysis, and there is a need for replication with more systematic analysis and a much larger set of data.…”

“…This includes studies of reaction times and supposed stepwise functions in perceptual judgment (e.g. Geissler et al, 1999;Pöppel, 1970;von Békésy, 1936) that were critically evaluated by Vorberg and Schwartz (1987) and Vroon (1970Vroon ( , 1974. The third and most problematic category is evidence that relates to periodicity in perceptual or attentive processing.…”

Is conscious perception a series of discrete temporal frames?

This paper reviews proposals that conscious perception consists, in whole or part, of successive discrete temporal frames on the sub-second time scale, each frame containing information registered as simultaneous or static. Although the idea of discrete frames in conscious perception cannot be regarded as falsified, there are many problems. Evidence does not consistently support any proposed duration or range of durations for frames. EEG waveforms provide evidence of periodicity in brain activity, but not necessarily in conscious perception. Temporal properties of perceptual processes are flexible in response to competing processing demands, which is hard to reconcile with the relative inflexibility of regular frames. There are also problems concerning the definition of frames, the need for informational connections between frames, the means by which boundaries between frames are established, and the apparent requirement for a storage buffer for information awaiting entry to the next frame.

“…Intervals for which more events can be recalled feel longer than intervals for which few events are remembered. In the storage size model, time judgements are relative to how much information is processed during an interval; the greater the amount of information and its complexity, the larger the size of the memory storage and hence, the longer the duration judgement (Ornstein, 1969;Thomas & Brown, 1974;Vroon, 1970). This model was criticized for relying on vague concepts that cannot be measured (Block, 1990).…”

The Effect of Emotion on Time Perception for Complex Visual Stimuli

<p>Activation and attention have opposite effects on time perception. Emotion can both increase physiological activation (which leads to overestimation of time) and attract attention (which leads to underestimation of time). Although the effect of emotion on time perception has received a growing amount of attention, the use of different time estimation tasks and stimuli makes it difficult to compare findings across studies. The effect of emotion on the temporal perception of complex stimuli (e.g. scenes) is particularly under-researched. This thesis presents a systematic assessment of the effect of two key emotional dimensions, arousal and valence, on time perception for visual stimuli. Studies were designed to control for factors that may modulate emotion effects, such as image repetition and carry over from one emotion to another. The stimuli were complex images standardized for arousal (high or low) and valence (positive or negative) as well as neutral images. The first study compared three time estimation tasks to determine which were sensitive to emotion effects. The selected task, temporal bisection, was used to test time perception in three duration ranges: short (400 to 1600ms), middle (1000 to 4000ms), and long (2000 to 6000ms). Results of bisection point analyses revealed that the duration of attention-capturing stimuli (e.g. high arousal or negative images) was underestimated compared to that of other stimuli (e.g. low arousal or neutral images). These findings are at odds with activational effects of emotion (overestimation of emotional stimuli), which are typically found in studies of time perception for facial expression. Better temporal sensitivity in the long range than in short and middle ranges suggests that participants used different timing strategies to perform the bisection task at longer stimulus durations. To test the effect of emotion on time perception using a discrete rather than dimensional classification of emotion, experiments were replicated using emotional facial expressions as stimuli. Time estimates in the short and middle ranges did not show attentional effects, but pointed to activational effects of emotion. Facial expression had no impact on time perception in the long duration range. Taken together, these experiments show that the effect of emotion on time perception varies according to both duration and stimulus type. Emotional facial expressions have short lived activational effects whereby the duration of arousing stimuli is overestimated, whereas complex emotional scenes have protracted attentional effects through which the duration of attention-capturing stimuli is underestimated.</p>
