Shen Shaomin

Posted in Uncategorized on June 17, 2013 by pauljohnwhite

I Sleep on Top of Myself and I Want to Know What Infinity Is are works (by Shen Shaomin) that reveal the artist’s outlook through hyperrealistic sculptures that illustrate the potential and metaphorical consequences of a world which is over-developed and despoiled.

I Sleep on Top of Myself is a series of hairless, motorized, lifelike sculptures of animals which portend a future where the earth is severely depleted of natural resources-so much so that animals begin to loose their fur. Trapped in deep sleep, these breathing creatures-a cat, a dog, a bunny, and two geese-are forced to sleep on the remnants of their fur and feathers in order to survive. As a metaphor, this quietly troubling piece asks if we humans will be forced to survive on the remnants of our past once we have exhausted all of our natural resources.

Through a similar methodology, I Want to Know What Infinity Is questions the urge to relentlessly develop and expand our economies at all costs. Similar to the way we strive for development, the old, naked, breathing hyperrealistic sculpture of a woman relentlessly strives for a perfect tan. In Shen Shaomin’s eyes, the consequences of our constant need for development will change the face of our planet, just as the undying urge for beauty transformed this old woman’s body.

Why Does Time Fly? Article describing experiments with subjective time experiences

Posted in Uncategorized on June 17, 2013 by pauljohnwhite

The following article describes how inducing particular emotional states can alter our perception of time, a valid and potentially interesting area of study for artists as well as scientists:

“Everybody knows that the passage of time is not constant. Moments of terror or elation can stretch a clock tick to what seems like a life time. Yet, we do not know how the brain “constructs” the experience of subjective time. Would it not be important to know so we can find ways to make moments last, or pass by, more quickly?

A recent study by van Wassenhove and colleagues is beginning to shed some light on this problem. This group used a simple experimental set up to measure the “subjective” experience of time. They found that people accurately judge whether a dot appears on the screen for shorter, longer or the same amount of time as another dot. However, when the dot increases in size so as to appear to be moving toward the individual — i.e. the dot is “looming” — something strange happens. People overestimate the time that the dot lasted on the screen.  This overestimation does not happen when the dot seems to move away.  Thus, the overestimation is not simply a function of motion. Van Wassenhove and colleagues conducted this experiment during functional magnetic resonance imaging, which enabled them to examine how the brain reacted differently to looming and receding.  

The brain imaging data revealed two main findings. First, structures in the middle of the brain were more active during the looming condition. These brain areas are also known to activate in experiments that involve the comparison of self-judgments to the judgments of others, or when an experimenter does not tell the subject what to do. In both cases, the prevailing idea is that the brain is busy wondering about itself, its ongoing plans and activities, and relating oneself to the rest of the world.

Second, brain areas including the left anterior insula were more active during the receding condition relative to the looming condition. The insula as a whole has been the focus of many recent studies and is thought to be involved in complex emotional processing.  In particular, Craig has suggested that there is an emotional asymmetry, in which the left forebrain is associated with approach, safety, positive affect and the right forebrain is associated with arousal, danger, and negative affect. An object moving away might be seen as non-threatening, signaling the self to relax. 

In fact, some investigators have suggested that the amount of energy spent during thinking and experiencing defines the subjective experience of duration.  In other words, the more energy it takes to process a stimulus the longer it appears as a subjective experience of time.  Something moving toward you has more relevance than the same stimulus moving away from you:  You may need to prepare somehow; time seems to move more slowly.

The experience of time is not linear. Fear and joy stretch time as do stimuli that move towards us.  What can we learn from these studies for our day-to-day experiences?  When we experience something as “taking a long time” it is really the result of three inter-twined processes: the actual duration of the event, how we feel about the event, and whether we think the event is approaching us.  There is little we can do about the first factor but there are obvious ways of modulating how we feel about an event and how we think about an event approaching us.  Future studies will need to address the question of whether modifying these factors can alter our subjective time experience so that that we can shorten life’s painfully extended moments of boredom and extend those wonderful moments of bliss.
