Inattentional Blindness is the failure to notice an unexpected object in a visual display.

Cognitive Psychology is an approach to understanding human cognition by observing behaviour of people performing cognitive tasks. It is concerned with the internal processes involved in making sense of our environment, and deciding what behaviour to be appropriate. These processes include attention, perception, learning, memory, language, problem-solving, reasoning, and thinking.

The most famous experiment that shows evidence for inattentional blindness is the Simons and Chabris (1999) experiment where an audience or viewer watches a group of people pass a ball to one another wearing either black or white, and a woman dressed as a gorilla enters the frame for 9 seconds, then walks off. Results reported that 50% of the observers did not notice the gorilla enter the frame. In all honesty, when I saw the video for the first time at university, I did not see the gorilla enter the frame either.

In reality, we are often aware of changes in our visual environment because we detect motion cues accompanying the change. This information suggests that our ability to detect visual changes is not only due to the detection of movement. An obvious explanation of the gorilla experiment findings is that the visual representations we form in our mind are sparse and incomplete because they depend on our limited attentional focus. Simons and Rensick (2005) point out that there are other explanations, such as: detailed and complete representations may exist initially but may either decay rapidly or be overwritten by a subsequent stimulus. It needs to be said that in the gorilla experiment, the observers are instructed to count how many times the ball passes, so really, our attention is deliberately compromised. The real-life implications of inattentional blindness reveals the role of selective attention in human perception. Inattentional blindness represents a consequence of this critical process that allows us to remain focused on important aspects of our world without distraction from seemingly irrelevant objects and events.

Being present, in the moment (mindfulness) can help aid our attention. Distractions such as using our mobile phones, advertising material, other people, “multi-tasking” and internal emotional states all contribute to our lack of focus and attention. Think of a magician’s ability to manipulate their audiences attention in order to prevent them from seeing how a trick is performed. There are also safety implications, as you would know … if you’ve been paying attention, haha.

Just food for thought, my readers, and friends 🙂

‘The stages of change model’ was developed by Prochaska and DiClemente. Heard of them? It informs the development of brief and ongoing intervention strategies by providing a framework for what interventions/strategies are useful for particular individuals. Practitioners need an understanding of which ‘stage of change’ a person is in so that the most appropriate strategy for the individual client is selected.

There are five common stages within the Stages of Change model and a 6th known as “relapse”:

1. In the precontemplation stage, the person is either unaware of a problem that needs to be addressed OR aware of it but unwilling to change the problematic behaviour [or a behaviour they want to change. It does not always have to be labelled as “problematic”].

2. This is followed by a contemplation stage, characterized by ambivalence regarding the problem behaviour and in which the advantages and disadvantages of the behaviour, and of changing it, are evaluated, leading in many cases to decision-making.

3. In the preparation stage, a resolution to change is made, accompanied by a commitment to a plan of action. It is not uncommon for an individual to return to the contemplation stage or stay in the preparation stage for a while, for many reasons.

4. This plan is executed in the action stage, in which the individual engages in activities designed to bring change about and in coping with difficulties that arise.

5. If successful action is sustained, the person moves to the maintenance stage, in which an effort is made to consolidate the changes that have been made. Once these changes have been integrated into the lifestyle, the individual exits from the stages of change.

6. Relapse, however, is common, and it may take several journeys around the cycle of change, known as “recycling”, before change becomes permanent i.e., a lifestyle change; a sustainable change.
