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 continued differential treatment of mental illness and addiction compared to physical illness by broader society is rooted in several factors:The continued differential treatment of mental illness and addiction compared to physical illness by broader society is rooted in several factors:

Historical Context

Historically, mental illness and addiction have been misunderstood and stigmatized. For much of history, these conditions were seen as moral failings or character flaws rather than medical issues. This has led to a persistent stigma that continues to influence societal attitudes.

Lack of Awareness and Education

There is still a significant lack of awareness and education about mental health and addiction. Many people do not understand that these conditions are medical issues that require treatment, just like physical illnesses. This lack of understanding contributes to negative attitudes and discrimination.

Media Representation

Media often portrays mental illness and addiction in a negative light, reinforcing stereotypes and misconceptions. These portrayals can shape public perception and contribute to the stigma surrounding these conditions.

Criminalization

Addiction, in particular, has been heavily criminalised. This has led to a perception of addiction as a criminal issue rather than a health issue, further entrenching stigma and discrimination.

Internalised Stigma

Individuals with mental illness or addiction often internalise the stigma they experience, leading to feelings of shame and low self-worth. This can prevent them from seeking help and support, perpetuating the cycle of stigma and discrimination.

Healthcare System

Even within the healthcare system, biases and stigma can affect the quality of care provided to individuals with mental illness or addiction. This can lead to inadequate treatment and support, further exacerbating the issue.

Social and Cultural Factors

Social and cultural factors also play a role in how mental illness and addiction are perceived. Different cultures have varying attitudes towards these conditions, which can influence how they are treated and supported.

The differential treatment of treatment-resistant substance use disorder (SUD) and treatment-resistant cancer by society can be attributed to several factors:

1. Perception of Control

Substance use disorders are often perceived as a result of personal choices or moral failings, whereas cancer is seen as an uncontrollable disease. This perception leads to stigma and blame towards individuals with SUD, while those with cancer are more likely to receive sympathy and support.

2. Historical Stigma

Historically, substance use has been stigmatised and criminalised, leading to a societal view that addiction is a choice rather than a medical condition. In contrast, cancer has been recognized as a medical condition requiring treatment and compassion.

3. Media Representation

Media often portrays substance use in a negative light, emphasising criminality and moral failure. Cancer, on the other hand, is often depicted with empathy and urgency, highlighting the need for medical intervention and support.

4. Healthcare System

The healthcare system has historically been more equipped to handle cancer treatment, with extensive research, funding, and specialized care. SUD treatment has lagged behind, with fewer resources and less comprehensive care options.

5. Complexity of Treatment

Treatment-resistant SUD involves complex psychological, social, and biological factors, making it challenging to treat effectively. Cancer treatment resistance, while also complex, has seen significant advancements in research and technology, leading to more effective treatments.

6. Social and Cultural Factors

Cultural attitudes towards substance use and addiction vary widely, with some societies viewing it as a personal failing. Cancer is generally viewed more universally as a disease that requires medical intervention.

How does methamphetamine (aka. crystal meth) affect the brain?How does methamphetamine (aka. crystal meth) affect the brain?

To answer that question, I’ll need to explain a part of the brain called the Limbic System.

Within the brain there is a set of structures called the limbic system. There are several important structures within the limbic system: the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus. The limbic system is among the oldest parts of the brain in evolutionary terms. It’s not just found in humans and other mammals, but also fish, amphibians, and reptiles.

The limbic system is the part of the brain involved in our behavioural and emotional responses, especially when it comes to behaviours we need for survival: feeding, reproduction and caring for our young, and fight or flight responses (https://qbi.uq.edu.au/brain/brain-anatomy/limbic-system).

The limbic system contains the brain’s reward circuit or pathway. The reward circuit links together several brain structures that control and regulate our ability to feel pleasure (or “reward”). The sensation of pleasure or reward motivates us to repeat behaviours. When the reward circuit is activated, each individual neuron (nerve cell) in the circuit relays electrical and chemical signals.

In a healthy world without addictive manufactured drugs, humans survive and thrive when they are rewarded for certain behaviours (cleaning, hard work, sex, eating, achieving goals etc), hence evolution has provided us with this feel-good chemical so that we will repeat pleasurable behaviours.

There is a gap between neurons called the synapse. Neurons communicate with each other by sending an electro-chemical signal from one neuron (pre-synaptic neuron) to the next (post-synaptic neuron). In the reward circuit, neurons release several neurotransmitters (chemical messengers). One of these is called dopamine. Released dopamine molecules travel across the synapse and link up with proteins called dopamine receptors on the surface of the post-synaptic neuron (the receiving nerve cell). When the dopamine binds to the dopamine receptor, it causes proteins attached to the interior part of the post-synaptic neuron to carry the signal onward within the cell. Some dopamine will re-enter the pre-synaptic nerve cell via dopamine transporters, and it can be re-released.

When a reward is encountered, the pre-synaptic nerve cell (neuron) releases a large amount of dopamine in a rapid burst. Dopamine transporters will remove “excessive” amounts of dopamine naturally within the limbic system. Dopamine surges like this help the brain to learn and adapt to a complex social and physical world.

Drugs like methamphetamine (a stimulant drug) are able to “hijack” this process contributing to behaviours which can be considered unnatural or potentially dysfunctional. A range of consequences can follow.

When someone uses methamphetamine, the drug quickly enters the brain, depending on how the drug is administered. Nevertheless, meth or ice is quick acting. Meth blocks the re-entry of dopamine back into the pre-synaptic neuron – which is not what happens naturally. This is also what cocaine does to the brain. However, unlike cocaine, higher doses of meth increase the release of dopamine from the presynaptic neuron leading to a significantly greater amount of dopamine within the synapse. Higher doses of cocaine will not release “more dopamine” from the pre-synaptic neuron like meth does. This is why after about 30 minutes or so, people who use cocaine will need more to maintain the high.

Dopamine gets trapped in the synapse (space between nerve cells) because the meth (like cocaine) prevents “transporters” from removing it back into the cell it came from. The postsynaptic cell is activated to dangerously high levels as it absorbs so much dopamine over a long period of time. The person using meth experiences powerful feelings of euphoria, increased energy, wakefulness, physical activity, and a decreased appetite.

When an unnatural amount of dopamine floods the limbic system like this over a long period of time, without reabsorption, then our brain is not replenished with dopamine, hence people who use meth often (even on a single occasion) may feel unmotivated, depressed, joyless, and/or pointlessness when they stop using. Figuratively speaking, the brain is “empty” or low on dopamine fuel, and it will take time to for dopamine to return to baseline levels and replenish itself. This may motivate the user to seek more methamphetamine to return to “normal”.

Methamphetamine can also cause a variety of cardiovascular problems, including rapid heart rate, irregular heartbeat, and increased blood pressure. Hyperthermia (elevated body temperature) and convulsions may occur with methamphetamine overdose, and if not treated immediately, can result in death (What are the immediate (short-term) effects of methamphetamine misuse? | National Institute on Drug Abuse (NIDA) (nih.gov))

The stages of change modelThe stages of change model

‘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.
