‘Self-objectification’ is the tendency to experience one's body principally as an object, to be evaluated
for its appearance rather than for its effectiveness. Within objectification theory, it has been proposed that self-objectification
accounts for the poorer interoceptive awareness observed in women, as measured by heartbeat perception. Our study is, we believe, the first
specifically to test this relationship.

A stressful situation — whether something environmental, such as a looming work deadline, or psychological, such as persistent worry about losing
a job — can trigger a cascade of stress hormones
that produce well-orchestrated physiological changes.
A stressful incident can make the heart pound and breathing quicken. Muscles tense and beads of sweat appear

Attention could be described as a spotlight that focuses your awareness on a particular facet of
your environment, or on the thoughts in your head. The ability to pay attention
to important things—and to ignore the rest—likely helped early humans survive and evolve.

The heart produces coherent contraction of numerous muscle cells, resulting in vigorous electrical activity. In fact, the heart
makes the greatest contribution to the electromagnetic, as well as the acoustic, human biofield. The brain’s activity contributes to a lesser
extent to the biofield because its field emission is weaker than that of the heart. The ECG was first developed in 1887 and records the electrical
activity from different areas of the heart. The EEG was developed in 1875 and records electrical
activity from the various brain regions by using multiple electrodes on the head.

Neuroscientist Carlos Grau of the University of Barcelona and colleagues set up a clever experiment in which signals
picked up by an Electroencephalagraph EEG from subjects in India were transmitted over the Internet as email messages to other subjects
in France whose scalps had been fitted with Trans Cranial Magnetic (TMS) stimulators. TMS devices, which have been used to treat anxiety and
depression, electrically stimulate neural activity in the brain through intact scalps using strong magnetic fields. In this experiment, TMS stimulators
were placed over the occipital (visual) cortex at the back of the brain,
creating a perceived flash of light, called a phosphene, through neural activations in the visual cortex.
