A Sensational Experience

Posted on by Jinavie

We use our senses to interpret the world around us. Thanks to photography, video and sound recording, we are able to preserve what we see and hear in our lives. If you have the good fortune of seeing an incredible view such as a beautiful sunset, you can take a photo, look at it ten years later and remember what it was like watching it with your own eyes. If you miss the sound of your loved one’s voice, you can record the sound and play it again.

However, we are still unable to record senses such as taste, smell and touch. No matter how hard you try, you can never perfectly describe the taste of your mother’s cooking, the soft touch that you felt during your first kiss, or the scent of the person you love to another person using just words. This means that these sensations are only in your memories – and yours alone.

It is a shame that you cannot recall these experiences perfectly, as some of our best memories are associated with them. But perhaps you could think of it from a romantic point of view. You can share a photo or a sound clip with others to share your experience – even make it public so that everyone can know of it. However, with things like taste and smell, only you will know and remember that specific sensation. It is a truly unique experience that belongs only to you (and the few others who were lucky to have tasted your mother’s cooking).

Furthermore, as it is only in your memories, the moment you forget about it, the experience will disappear forever. Maybe that is why people cling to nostalgia of these senses – because it is a fragile yet precious thing that is worth treasuring and holding on to.

The Importance Of Hugging

Posted on by Jinavie

American psychologist Harry Harlow was interested in the debate surrounding the role of the mother. Some scholars argued that a mother’s role is to provide food for the baby, while others argued for the importance of the mother’s tender loving care for the baby. To investigate this, Harlow created two “mothers” for a group of infant rhesus macaques (species of monkeys). One mother was made of wire and wood and the other made of soft cloth to simulate the physical contact of an actual mother monkey. The twist was that only the wire mother provided milk for the infant. Despite this, an overwhelming number of infant macaques chose the cloth mother over the wire mother, choosing physical contact over nourishment. It was found that when given the two choices, the infants would visit the wire mother only for a feed, then would cling to the cloth mother the rest of the time. Harlow concluded that the mother’s role is not only to feed the young, but to provide them with “contact comfort” through physical contact.

Hugging is a form of physical contact found in almost every culture across the globe. It non-verbally communicates to the other person that you love and care for them and that you are compassionate for their happiness. It can provide the warmth, comfort, support and security the other person may need at the end of a tough day.

The act of hugging induces a massive release of oxytocin into your system, giving you the sensation of happiness and connection. It reduces your blood pressure and dissolves anxiety, making you feel more at peace. The behaviour of hugging is seen in a mother holding her child, a child cuddling a teddy bear, a couple communicating their affection, or two friends sharing a moment of happiness.

When two people hug, they become something more than a simple group of two people. In that moment of a hug, the two people enter a transcendent zone filled with only love and happiness, where they are protected from the sorrows and evils of the world. It is the physical form of human connection. In other words, a hug is the closest thing to the physical manifestation of true happiness.

An Opinion On The Senses

Posted on by Jinavie

There are five physical senses and five mental senses.

The physical senses are sight, hearing, touch, taste and smell.

The mental senses are emotions, imagination, intuition, understanding and inspiration.

If a person only uses their five physical senses to live, that is like using the five fingers on their left hand only.

(Die fünf Sinne (The Five Senses) by Hans Makart, 1840-1884)

Sensory Illusion

Posted on by Jinavie

The five senses we use to experience the world are simply wondrous. However, thanks to our not-so-perfect brain, these senses can easily be distorted. Illusions are a very good way to show how the brain processes sensory information and there are many fascinating examples.

Almost everyone has seen an optical illusion before, such as Penrose’s endless stairs or the Muller-Lyer illusion. There are countless more examples such as static pictures that appear to be moving and illusions in colour perception (A and B are the same colour). This is caused by the brain not recording images like a camera, but rather processing visual information and reconstructing an image. There are four main types of optical illusions: ambiguous (e.g. rabbit or duck), distortion (Café wall illusion), paradoxical (Penrose triangle) and fictional (only seen in hallucinations or by schizophrenics).

(Do you see the dolphins? Children cannot see the man and woman because they cannot comprehend it, whilst adults cannot overpower the sexual image)

Like vision, every other sense can be fooled in a similar fashion.
Auditory illusions that distort what we hear are fairly common, a good example being the infinitely ascending Shepard scale (which are just a series of the same ascending octave scale). Also, the McGurk effect shows how the brain uses a multimodal approach where it involves both hearing and vision when listening.

There are also tactile illusions. For example, if you pull your top lip to left and the bottom lip to the right, then prod the middle of the lips with a pencil, it feels like there are two. However, the more famous case is of the Phantom Limb, where an amputee’s brain still believes that the limb is there, causing it to “feel” the limb or even feel pain.

The other two senses aren’t as famous in terms of illusions, but definitely exist.
Smell is easy to fool through chemicals as it is the physiological method of detecting smell. It also exhibits olfactory fatigue where it becomes desensitised to a strong smell.
Taste illusions are more fascinating and easily seen. They are caused by two or more tastes forming a synergy to produce a completely different taste. For instance, mixing barley tea and milk produces a coffee milk taste, while cucumber and honey tastes like melons.
A more fascinating illusion involves Miracle Fruit Berries, which contain a substance called miraculin that distorts the taste of sourness to sweetness.

This shows how we can fool all five senses, and learn more about the mysterious organ that is the brain.
