Inattentional Blindness: What else are we missing?

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.

Re-write: Distract!

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 Concept of the "Triune Brain"

In the 1960s, American neuroscientist Paul MacLean formulated the ‘Triune Brain’ model, which is based on the division of the human brain into three distinct regions. MacLean’s model suggests the human brain is organized into a hierarchy, which itself is based on an evolutionary view of brain development. The three regions are as follows:

  1. Reptilian or Primal Brain (Basal Ganglia)
  2. Paleomammalian or Emotional Brain (Limbic System)
  3. Neomammalian or Rational Brain (Neocortex)

At the most basic level, the brainstem (Primal Brain) helps us identify familiar and unfamiliar things. Familiar things are usually seen as safe and preferable, while unfamiliar things are treated with suspicion until we have assessed them and the context in which they appear. For this reason, designers, advertisers, and anyone else involved in selling products tend to use familiarity as a means of evoking pleasant emotions.

Three rules for identifying abnormal child sexual behavioursThree rules for identifying abnormal child sexual behaviours

Retrieved and edited 06/12/2021 from “Voice of Experience: Three rules for identifying abnormal child sexual behaviors” by Gregory K. Moffatt, a veteran counsellor with more than 30 years experience. If you are a survivor of sexual trauma at any age, I encourage you not to read this article.

From the perspective of Moffatt’s professional experience, childhood sexual behaviours can be grouped into three categories: 1. normal behaviours, 2. behaviours that are not normal but not unusual, and 3. behaviours that are abnormal or statistically rare. For the purpose of this post, I will be replacing the word “normal” with “natural” and/or “common” moving forward.


Rule No. 1: Natural or common sexual behaviours in children are never forced. The exploration is mutual. While one child likely had the idea first, both children must participate freely. This doesn’t mean that two children might willingly agree to engage in abnormal sexual behaviours, however, therefore read the next to rules for clarification.


Rule No. 2: Natural or common sexual behaviours in children are never painful. Children who behave within cultural and developmental norms will stop what they are doing when they realise they have caused pain.


Rule No. 3: Natural or common sexual behaviour in children is never invasive. Natural childhood curiosity does not include inserting objects or one’s own body parts into the cavities of others — anus, vagina, mouth, etc.


I’m unsure why Moffatt didn’t make this a 4th rule – he did add that most of the time, this type of childhood behaviour occurs between children of similar age. It is highly unusual for a young child to sexually engage with a teen without violating one of the three rules above. That behaviour definitely calls for further investigation. And, certainly, any sexual interaction between an adult and a child is cause for mandated reporting.
