Effect of Tunneling and Broadening of Frequency on Ability of Unfilled Time Judgment

The present study examined the effect of tunneling and broadening of frequency on ability of unfilled time judgment. Twenty male post graduate students were participated, it was asked to estimate the time of tone which was randomly presented to the participants with different frequency. The stimuli in this experiment were basically a series of consecutive two stimuli of the same sound / intensity [Control Condition 440Hz-440Hz]. The stimuli were presented in low to high intensity in Experimental Condition One [220Hz-660Hz] and high to low frequency in Experimental Condition Two [660Hz-220Hz].The underestimation of time has occurred more in the Control Condition than the other two Experimental Conditions. But the underestimation of time has occurred accurately in Experimental Condition Two than Experimental Condition One. The tunneling effect has affected more on time estimation than the broadening effect of the participants.
