A transient suppression of visual perception during saccades ensures perceptual stability. In two experiments, we examined whether saccades affect time perception of visual and auditory stimuli in the seconds range. Specifically, participants completed a duration reproduction task in which they memorized the duration of a 6 s timing signal during the training phase and later reproduced that duration during the test phase. Four experimental conditions differed in saccade requirements and the presence or absence of a secondary discrimination task during the test phase. For both visual and auditory timing signals, participants reproduced longer durations when the secondary discrimination task required saccades to be made (i.e., overt attention shift) during reproduction as compared to when the discrimination task merely required fixation at screen center. Moreover, greater total saccade duration in a trial resulted in greater time distortion. However, in the visual modality, requiring participants to covertly shift attention (i.e., no saccade) to complete the discrimination task increased reproduced duration as much as making a saccade, whereas in the auditory modality making a saccade increased reproduced duration more than making a covert attention shift. In addition, we examined microsaccades in the conditions that did not require full saccades for both the visual and auditory experiments. Greater total microsaccade duration in a trial resulted in greater time distortion in both modalities. Taken together, the experiments suggest that saccades and microsaccades affect seconds range visual and auditory interval timing via attention and saccadic suppression mechanisms.

Summary: Different shapes of individual subjective discount functions were compared using real measures of willingness to accept future monetary outcomes in an experiment. The two-parameter hyperbolic discount function described the data better than three alternative one-parameter discount functions. However, the hyperbolic discount functions did not explain the common difference effect better than the classical discount function. Discount functions were also estimated from survey data of Dutch households who reported their willingness to postpone positive and negative amounts. Future positive amounts were discounted more than future negative amounts and smaller amounts were discounted more than larger amounts. Furthermore, younger people discounted more than older people. Finally, discount functions were used in explaining consumers' willingness to pay for an energy-saving durable good. In this case, the two-parameter discount model could not be estimated and the one-parameter models did not differ significantly in explaining the data.

We study the problems of time consciousness from the standpoint of philosophy, physics and psychology; it is argued that such a sequence in the analysis of the problem allows us to reveal the actual psychological aspect of the problem of the objectivity of the consciousness of time, which is the goal of the study. Both the philosophical concepts of the time consciousness of I. Kant, E. Husserl and F. Brentano, and the physical theories of the study of time (quantum physics, cosmology, the physics of non-equilibrium processes) are analyzed. It has been established that in philosophical theories, the concepts: consciousness, memory, perception, representation, and others do not have clear definitions and can change their meaning depending on the context. It is emphasized that in physical and human sciences time is investigated, as a rule, in connection with the concept of “space”. It is shown that when analyzing the problem of the consciousness of time, one should first decide on the concept of “reality”, which allows us to remove contradictions in the understanding of time in various physical theories. It is concluded that the existence of both objective and subjective time can only be spoken when we operate with concepts; outside of this the concept of “time” has meaning only when a person is considered as part of society. It is shown that in relation to the collective and personal unconscious, the temporal modes of the "past", "present" and "future" do not make sense, since "the whole diversity of everything" is represented in the unconscious field simultaneously and extra-spatially.
