The Enraged Musician – by Hogarth
“An exogenous cue is an external event such as the
abrupt onset of a stimulus at a peripheral location that involuntarily
draws the attentional spotlight to its location. […] An endogenous cue is
typically a symbol such as a central arrow head that must be identified before
a voluntary shift in attention to the designated location can be made […]
indicating that their benefits are due to conscious control of the attentional
spotlight.” – Historical Overview of
Research on Attention by Johnson
“The taking possession by the mind, in clear and
vivid form, of one of what seem several simultaneously possible objects or
train of thought.” – William James’s definition of attention.
In the painting, the musician is clearly annoyed at
the many various distractions immediately outside window. It is an exaggeration
of the hubbub of city life. As the musician is trying to concentrate his
attention upon his classical music-making, he is unable to do so because the
same modes of sensation needed to listen to his own music is being overrun by
the lingering noises on the outside of his window.
This
depiction of distraction may serve as a good example of exogenous control versus endogenous
control of attention. As stated in the quote above, exogenous control of
attention refers to a passive, almost reflex-like, attention in which it is
non-voluntary and is being controlled by external influences (i.e. loud noises,
visual cues – spotlight). On the other hand, endogenous control of attention is
the active and voluntary type of attention; this type of attention is commonly
associated with a more voluntary activation of specific stimulus (i.e. reading,
manual labor).
Recent
studies (post-1975) show that it is hard to use multitask when the tasks being
performed use the same stimulus or response modalities (Johnson p.20). “Multiple
task performance typically is better when the tasks use different input-output
modes than when they use the same modes.”
Relating this back to the Enraged
Musician, we can assume that the exogenous control of his attention via
loud noises is overpowering the same stimuli needed for his endogenous control
of attention toward his music; here, exogenous
attention is distracting by taking away from his endogenous attention’s “clearness” (James’s definition of
attention).
Taking
into account the excerpts and interpretations above, attention can be thought
of as the currency for mental activity – philosophers seem to attribute the action
of directing attention with a cost of brain processing power – and it is
limited. Thus, since the brain compartmentalizes all its modes of sensation and
reflection spatially, multitasking tends to get harder when the multiple tasks
(brain activity) use the same brain space as opposed to spreading out the
work-load to various compartments of the brain. This is personified in Hogarth’s
painting in that the musician is annoyed at the fact that he cannot focus all
of his attention to playing the violin.
