If you had to pay attention to everything, you’d be overwhelmed by the information overload. As William James explained in his book The Principles of Psychology, published in 1890, attention is not just about what you observe but also about what
you choose not to observe. He wrote: “It implies withdrawal from some things in order to deal effectively with others.” Being able to ignore most of what we see or hear is essential for survival. We can switch our attention, sometimes
through conscious effort, but sometimes because of a sudden change, such as a flash of light or sudden movement.
Selective attention allows us to ignore anything that doesn’t appear relevant or we are not expecting. The gorilla in the room has been used in countless presentations and courses to illustrate this point.
With workplace inspections or audits, or when collecting information for a risk assessment, we need to improve our ability to observe even those things we are not expecting, or that might initially seem irrelevant. A well-written checklist can guide the
observer so that they notice the existence or the omission of all the items listed. However, a checklist can also distract the observer, making it less likely that the individual will see other hazards that are not listed.
The act of attempting to draw will help you to focus on details
Research suggests people can be trained to make better observations. One technique is to draw an image (even if you’re not a good artist). The act of attempting to draw will help you to focus on details, learning to look at your surroundings with
a fresh perspective.
The Campbell Institute (part of the US National Safety Council) ran a pilot study, in which staff were trained in “visual literacy” (this will be the focus of a future
article in IOSH Magazine). This involves looking for lines, shapes, colours, textures and space. For example, wavy lines might indicate a trailing cable, the texture of the floor might indicate a slip hazard or looking for yellow might help
observe the presence or absence of personal protective equipment.
The institute reports that at one manufacturing site 25 hazards were identified and corrected using visual literacy techniques. Although there was no before comparator for this statistic, the organisation could demonstrate that workers’ perception
of the risk from machines, slips and trips, and falls from height all increased after visual literacy training.
Observation is not only about looking in the right place. Psychologist Gustav Kuhn, the author of Experiencing the Impossible: the science of magic, explains: “People don’t fail to notice things simply because they are not looking in the right
place; they miss things because their mind is misdirected. Our work shows that people can look directly at something, yet they still do not see it.”
As well as listening and looking for body language signals and cues, observing how you feel is important, for example, sensing frustration or anxiety
Misdirection in magic is similar to dual task interference in psychology. The driver using their mobile phone doesn’t observe the pedestrian about to cross the road; the worker thinking about the time pressures they are under doesn’t notice
the warning light on the machinery; and the auditor writing reams of notes about what they have seen so far might miss the next hazard they walk past.
Observation is not restricted to what you can see. It should include listening to voices and sounds, sensing temperatures and smells. OSH practitioner and coach Michael Emery goes further. He says: “As well as listening and looking for body language
signals and cues, observing how you feel is important, for example, sensing frustration or anxiety.”
What we observe depends on our experiences and interests. Joint audits between full-time safety and health professionals and workers’ representatives or bringing in people from other departments are likely to improve the quality of the observations.
Bringing someone new to a workplace overcomes the familiarity bias.
Next time you’re sitting in a cafe or work canteen on your own, instead of getting out your laptop or phone, develop your observational muscles for all your senses.
