Wearing weighted backpack dilates subjective visual duration: the role of functional linkage between weight experience and visual timing.

Jia L, Shi Z, Feng W - Front Psychol (2015)

Bottom Line: The results showed that the subjective duration of the backpack picture was dilated when participants wore a medium weighted backpack relative to an empty backpack or without backpack, regardless of identity (e.g., color) of the visual backpack.The congruent action affordance between the wore backpack and visual inputs plays a critical role in the functional linkage between inner experience and time perception.We interpreted our findings within the framework of embodied time perception.

ABSTRACT
Bodily state plays a critical role in our perception. In the present study, we asked the question whether and how bodily experience of weights influences time perception. Participants judged durations of a picture (a backpack or a trolley bag) presented on the screen, while wearing different weight backpacks or without backpack. The results showed that the subjective duration of the backpack picture was dilated when participants wore a medium weighted backpack relative to an empty backpack or without backpack, regardless of identity (e.g., color) of the visual backpack. However, the duration dilation was not manifested for the picture of trolley bag. These findings suggest that weight experience modulates visual duration estimation through the linkage between the wore backpack and to-be-estimated visual target. The congruent action affordance between the wore backpack and visual inputs plays a critical role in the functional linkage between inner experience and time perception. We interpreted our findings within the framework of embodied time perception.

Figure 1: Visual pictures used in three experiments for duration judgments. (A) The blue backpack picture presented in Experiment 1, and participants wore this type of backpack in all experiments; (B) The orange backpack picture used in Experiment 2; (C) The small trolley bag picture used in Experiment 3.

Mentions: The experiments were conducted in an isolated cabin with dim lit environment. Visual stimuli were presented on a 21-inch CRT monitor with a refresh rate of 100 Hz. Visual stimuli consisted of the following pictures: blue and orange backpacks (12 cm × 9 cm), small gray business trolley bag (10 cm × 10 cm, see Figure 1). Participants were asked to keep standing and holding a light response box during blocks. The viewing distance was kept at 57 cm. Visual stimuli presentation was controlled by Matlab program using Psychophysics Toolbox (Brainard, 1997).
