Attention is a process by
which we actively engage with specific information from our environment. For listeners
this could be a symphony playing on the radio with random additional material such
as a pressure cooker steaming away as you prepare your midday meal, the postman
delivering letters and two crows squawking outside your window. I imagine many
of you will ask the relevant question: how do we manage to experience all of
these sensations and still focus on just one element? In order to get to terms
with this, and determine whether we can focus on a preferred element, we must
understand the process of withdrawal, bottlenecks and shared tasks.
There must be a number of musicians who have experienced the wonderful
sense of rapture arising from listening when we are so engaged on the “primary
target” that all secondary inputs have zero impact, we have tuned in to one
element and seemingly tuned out all others.
Readers of these blogs who have taken on the psychological arguments in
relation to music will be well aware of the basic requirements of attention for
survival. Here our interest is directed towards limitations on our ability to
stay on task, and what we can do to maximise contact with music, especially as
we know instinctively that our attention is limited in terms of both capacity
and duration. How selective can we be and what do we miss when we are
selective? Are certain senses more powerful than others, is there a peak point
at which visual or aural material creates an overload on attention?
Posner and Boies (1971) suggested that attention has multiple
sensory functions, for musicians the two of significance are detecting signals
for focused processing, and maintaining a vigilant or alert state. Other psychologists have used terms such as
arousal, effort, capacity, perceptual set, control, and consciousness as
synonymous with the process of attention, I am sure that performers and
composers alike feel comfortable with these terms.
Attention involves selecting some information for further
processing while inhibiting other information. Understanding attention is as
much about filtering information as selection. This creates two states change
blindness (Simons & Rensink, 2005) and change deafness (Vitevitch, 2003). In
examining how partial our attention can be, psychologists are exploring the
notion of top-down processing, a flexible and dynamic approach to attention as
what is important at one moment may no longer be so at the next, and our goals
shift accordingly.
Knowledge, beliefs, goals and expectations can alter the
speed and accuracy of the processes that select meaningful or desired
information; what we might think of as scanning and selecting material.
However, because of the variety and quantity of information available in (say)
a concert hall, top-down attentional selection does not always lead immediately
to your goal, in our case focused listening. The recognised term for our
attempts to direct attention is “mental effort” which accepts that given two
sources of information we are not able to give equal weighting to both.
Just as there are limitations on the quantity of information
that can be processed simultaneously in space, there are limitations on the
speed with which information can be processed in temporal sequence. There are
suggestions that we are limited by sensory overload, a bottleneck of
information, certain critical mental operations have to be carried out sequentially
(Pashler & Johnston, 1998).
When our attention requires a physical response this will
create a bottleneck, good sight-readers have developed the knack of shifting
attention back and forth at a rapid pace. As with multiple sensory inputs,
coordinating two output responses is more difficult than simply making a single
response. It is not impossible to do two things at once, and as musicians are
well aware, we can get better at this with practice, but there is usually some
associated cost or failure even when one is skilled.
As suggested the effective strategy for multitasking is to
switch quickly back and forth between the two tasks rather than try to deal
fully with both simultaneously. Before becoming expert sight-readers we may
break down the process into smaller units with longer periods of rest to
determine levels of accuracy and regions of faults (rhythm, wrong notes, lack
of articulation etc.). We still do not know whether it is possible to perform
two tasks at exactly the same time or, if it is, what happens to the quality of
the attention paid.
Now that we have an outline of memory from the previous blog and a
general understanding of attention it is time to turn to how some people absorb
music and problems faced with attention when listening.
Several years ago I worked with a youngster who had a number of
difficulties with learning, without going into details his literacy and
numerical skills were very weak as was his retention of factual material. It
came as a great surprise to me one day when I heard him reciting streams of rap
along with stylistic gestures and intonation. I asked him to perform in front
of his peers and he did without hesitation or any signs of anxiety, (unlike
many of the more gifted performers I had worked with). It would seem that he
had been involved in a high level of rehearsal having given considerable
attention to performance detail picked up from audio and video sources. His
passion for this style of music cut through the obstacles which were inhibiting
his other learning. I can attest to the fact that he wanted to be equally able
with other studies, particularly his numeracy, but for both of us this was an
uphill struggle.
The Welsh have a tradition of storytelling and reciting and I have
observed the capacity for some people to absorb large quantities of verse with
little apparent effort. (In medieval times the expectation for any storyteller
was to know 10,000 lines of verse). To be able to recite or sing in this way
there has to have been detailed contact with the subject matter, but not
necessarily all at once. The content may have been absorbed in chunks, starting
with the gist and then adding to this until a complete performance is absorbed.
Chunking material is part and parcel of music, we are well aware
of the role of repetition which contributes to our attention and recall of
larger works, but chunking works on small scale events as well as larger formal
units. Musicians are adept at matching and comparing related phrases through
transposition, inversion and a whole host of methods of variation.
As can be seen from the wiki definition below the psychological
definition is adaptable to the musicians approach:
Chunking in psychology is a process by which individual
pieces of information are bound together into a meaningful whole. A chunk is
defined as a familiar collection of more elementary units that have been
inter-associated and stored in memory repeatedly and act as a coherent,
integrated group when retrieved.
In a design like sonata form we have motives
and rhythmic elements repeated many times within a section then aspects of
these elements extended before a recapitulation. This provides the listener
several opportunities to refresh his/her contact with the music, and this is
important because our attention is in a constant state of disruption.
Over the past few months I have kept a
diary of my listening, or to be more explicit, a diary of how often my
attention has wandered while listening. It could make for depressing reading in
that every session has a number of breaks which paints a poor picture of the
contact I have with music. On the up side I know that I have a good recall of
many musical works and can replay significant sections in my head, or match a
score with an “aural impression” of the sound without a recording. In the early
years of listening to Classical music I know that I would pick out significant
details and build onto these, gluing a number of parts together to form a more
continuous experience of the musical logic. At this stage of my life I have a
little more difficulty in absorbing music, but my listening experience helps me
to form a stronger set of references on which I can draw to build up
familiarity, so one loses a little and gains a little.
The diary was particularly useful in
showing what sorts of interference came between me and the music, it was nearly
always involved with problem solving. In the middle of a piece I would become
absorbed by any tasks that were incomplete, sometimes musical, sometimes far
more trivial. Having become aware of this I tried to resolve any issues before
listening only to find that my mind would conjure up issues from further back
in time or of less significance. In other words I had formed a habit.
For many people music is regarded as a
form of relaxation, in this state turning inwards to problem solving is
acceptable as long as the listener is aware that the attention to the music is
diminished. We can attend to two tasks, but never equally.
Don’t be harsh on yourself if you
discover that your attention has lost its focus, go back (if you can) to the
point at which you lost contact. It may be that there is an issue at that point
which requires detailed observation and dealing with it may be of use in the
future. Sometimes several returns are necessary, but remember rehearsal is
vital to our long term memory.
