“…For example, in addition to using directly interpretable measures of SNS activity, future studies could also employ other non-invasive physiological measures, such as eyeblink rate or pupillometry. On the other hand, an assessment of action, as opposed to choice impulsivity (such as a Go-Nogo task), or personality traits, may also be desirable (Glicksohn et al, 2006). It would also be of interest to investigate whether the observed correlations between cardiac measures and time perception would extend to other time estimation paradigms, such as a temporal bisection task, or shorter or longer intervals.…”

Cardiac Signals Are Independently Associated with Temporal Discounting and Time Perception

Cardiac signals reflect the function of the autonomic nervous system (ANS) and have previously been associated with a range of self-regulatory behaviors such as emotion regulation and memory recall. It is unknown whether cardiac signals may also be associated with self-regulation in the temporal domain, in particular impulsivity. We assessed both decision impulsivity (temporal discounting, TD) and time perception impulsivity (duration reproduction, DR) in 120 participants while they underwent electrocardiography in order to test whether cardiac signals were related to these two aspects of impulsivity. We found that over the entire period of task performance, individuals with higher heart rates had a tendency toward lower discount rates, supporting previous research that has associated sympathetic responses with decreased impulsivity. We also found that low-frequency components of heart rate variability (HRV) were associated with a less accurate perception of time, suggesting that time perception may be modulated by ANS function. Overall, these findings constitute preliminary evidence that autonomic function plays an important role in both decision impulsivity and time perception.

“…Glicksohn and his colleagues have investigated the effects of personality traits and attention load on intercepts and slopes for reproduction based psychophysical functions. One study [16] shows a decreased slope for high sensation seekers and another [17] shows no effect on slope, but an increase in intercept for low sensation seekers relative to base line for both low and high overload and for high sensation seekers for high attention load only. Hemmes et al found lower exponents and higher intercepts when participants engage in an attention demanding secondary task.…”

“…the average magnitude of over or under estimation, as the main dependent variable. Most investigations of non-time variables, such as mood, psychopathology, concurrent task, or drugs, use this approach [16], [19], [20], [21], [22], [23]. A variety of methods have been used to get psychological time estimates: including bisection, generalization from a target reinforced duration, categorisation, and the ratio of psychological to time, as well as magnitude estimation and production, see [24] for review.…”

Time Perception and Depressive Realism: Judgment Type, Psychophysical Functions and Bias

The effect of mild depression on time estimation and production was investigated. Participants made both magnitude estimation and magnitude production judgments for five time intervals (specified in seconds) from 3 sec to 65 sec. The parameters of the best fitting psychophysical function (power law exponent, intercept, and threshold) were determined individually for each participant in every condition. There were no significant effects of mood (high BDI, low BDI) or judgment (estimation, production) on the mean exponent, n = .98, 95% confidence interval (.96–1.04) or on the threshold. However, the intercept showed a ‘depressive realism’ effect, where high BDI participants had a smaller deviation from accuracy and a smaller difference between estimation and judgment than low BDI participants. Accuracy bias was assessed using three measures of accuracy: difference, defined as psychological time minus physical time, ratio, defined as psychological time divided by physical time, and a new logarithmic accuracy measure defined as ln (ratio). The ln (ratio) measure was shown to have approximately normal residuals when subjected to a mixed ANOVA with mood as a between groups explanatory factor and judgment and time category as repeated measures explanatory factors. The residuals of the other two accuracy measures flagrantly violated normality. The mixed ANOVAs of accuracy also showed a strong depressive realism effect, just like the intercepts of the psychophysical functions. There was also a strong negative correlation between estimation and production judgments. Taken together these findings support a clock model of time estimation, combined with additional cognitive mechanisms to account for the depressive realism effect. The findings also suggest strong methodological recommendations.

“…» (Moeller et al, 2001, p.î784). Selon Postei ( Cette définition de l'impulsivité laisse place à plusieurs facteurs qui doivent être précisés et cela peut être conceptualisé selon trois formes distinctes : soit motrice (Reynolds et al, 2006), cognitive (Glicksohn, Leshem, & Aharoni, 2006) et affective (Koenigsberg et al, 2002). Ces trois formes constituent le premier pas vers une qualification plus précise du concept.…”
