Anticipatory time (e.g., prospective duration into the future) is one of the key pieces of information to be processed in intertemporal decisions decisions requiring a tradeoff between smaller sooner and larger delayed outcomes. Extensive research has examined human and animal perception of time as it is currently passing (i.e., experienced time) and time that has already passed (i.e., retrospe...

This case study examines the hazard and risk perception and the need for decontamination according to people exposed to soil pollution. Using an ecological-symbolic approach (ESA), a multidisciplinary model is developed that draws upon psychological and sociological perspectives on risk perception and includes ecological variables by using data from experts' risk assessments. The results show t...

Psychoacoustics is the science of the relationship between physical quantities of sound and subjective hearing impressions. To examine these relationships, physical parameters, such as sound pressure level, frequency and modulation depth, are mapped to hearing-related parameters. Unlike the physical quantities, these hearing-related quantities – also referred to as psychoacoustic parameters – p...

Despite researchers’ efforts to develop models for successful aging, there is still no academic consensus on the definition of the term [3,4]. There are three main explanatory models on successful old age: the Rowe and Kahn model [5] The Socio-Emotional Selectivity1 and the Corrective and Preventive Proactivity [6]. We also highlight researches focused on the subjective perception of the elderl...

In this article a method of computing similarity of two Chinese pop songs is presented. It is based on five attributes extracted from the audio signal. They include music instrument, singing voice style, singer gender, tempo, and degree of noisiness. We compare the computed similarity measures with similarity scores obtained with subjective listening by over 200 human subjects. The results show...

The literature on time perception is discussed. This is done with reference both to the "cognitive-timer" model for time estimation and to the subjective experience of apparent duration. Three assumptions underlying the model are scrutinized. I stress the strong interplay among attention, arousal, and time perception, which is at the base of the cognitive-timer model. It is suggested that a mul...

The subjective visual vertical is determined when a subject judges the orientation of an indicator (e.g. a short line segment) as apparently vertical. The mechanisms that underlie this perceptual performance are usually assumed to be based predominantly on bottom-up processing of primarily vestibular and visual information. However, it is also possible that top-down processes play a role in suc...

What brings together Henri Bergson's Matter and Memory and JeanPaul Sartre's Imagination and The Psychology of Imagination is the question of the ontology of the image. Bergson attempts to use the image to bridge the gap between mind and matter by refusing to distinguish clearly between what he calls “matter-images,” “perception-images,” and “memory-images.” By defining both consciousness and t...

Subjective time perception implies connection to cognitive functions, attention, memory and awareness, but a little is known about connections with homeostatic states of the body coordinated by circadian clock. In this paper, we present results from experimental study of subjective time perception in volunteers performing physical activity on treadmill in various phases of their circadian rhyth...
