We live in an ever increasing technological world. In the past 50 years things have changed more rapidly for technological development than in the previous 100 years before that. How much has all of this technological development affected our brains and how we live in the modern age?

# Attention
<center><img src="https://storage.googleapis.com/steemimgimgs/2016/10/16/640px-Butterfly_Goldfish_026e22b.jpg" alt="640px-Butterfly_Goldfish_026e22b.jpg" border="0"></center>

Attention spans are down. That seems to be the case the more we study our current condition.

A 2015 study of 2000 Canadians reported an average attention span of 8 seconds, contrasting the earlier 2000 attention span of 12 seconds. A goldfish has an attention span of 9s. We seem to be devolving... 

It's not looking good for the new generation either. 87% of 2000 teachers in Puerto Rico said the attention span of children is shorter. Similarly, in UK, out of 400 teachers and 2000 parents, 70% say the attention span of children is not what it used to be.

With technology, we have an increased desire for immediate attention gratification, and a decreased ability to focus and be patient.

# Mood

Some people are more affected by technology use. Heavy internet users show more signs of depression. 

Dr. Arie Sigman says "There is a relationship between the amount of time you spend on social media and increased body dissatisfaction. High consumption of idealised images seems to activate neural networks in the brain like the amygdala, associated with fear and anxiety."

The influence of contrasting information to your self-view or worlview can be wrought with fear and anxiety. Some of it more legitimate than others, i.e. contrasting truth and falsity in morality vs. contrasting physical appearances.

Some people who are more into the technology and internet use it because they are depressed. There is no direct causal link to the correlation between heavy internet use and depression.

# Memory

Short-term memory is affected by our use of technology, while long term memory requires more study.

As we use more technology as a store and recall of information, we are less reliant on our own memory. We engage in 'cognitive offloading' and a symbolic 'digital dementia' develops. There is a shrinking in frontal lobe that is responsible for planning and organization. This might just be for internet addicts, and not regular users. 

Depending on technology for memory recall also makes memories less vivid in our internal-"reality" of consciousness imagination factory. People who look at objects for later recall of the objects and of their details, perform better than those who take pictures who also attempt to do memory recall.

The advantage to offloading memories to technology is that we have less clutter and more room for new information and memories to be stored.

# Social Skills
<center><img src="https://storage.googleapis.com/steemimgimgs/2016/10/16/social-media-581783_6408515e.jpg" alt="social-media-581783_6408515e.jpg" border="0"></center>

Social media is a new hangout location in a virtual reality. For those that are already predisposed to disengaging in objective reality, this can be a danger for their social development.

In our families, we tend to spend more time looking down on our devices, which results in less face time with parents compared to previous generations. This affects our ability to recognize facial expressions. Dr Arie Sigman says "they [excessive internet users] find it more difficult to read faces in experiments". 

But, the internet and technology makes learning faster, and more easily accessible unlike any previous generation. We just need positive influences, from caring peers and adults, who support and guide children to better sources of media to learn and develop from.

# Sleep

Bedtime screen use will change your sleeping patterns.

Blue light emits a frequency found in sunlight that tells the pineal gland to stop producing melatonin, which is the sleep hormone. This keep us awake and alert more to pay attention to the light-emitting device.

We spend more time each day texting or gaming than sleeping, by 20 minutes now.

I don't do texting or gaming, but I do spend more time on my computer than I do sleeping.

# Reading
<center><img src="https://storage.googleapis.com/steemimgimgs/2016/10/16/360px-Bouquin_electronique_iLiad_sur_une_pile_de_livre_dehors_au_soleild6492.jpg" alt="360px-Bouquin_electronique_iLiad_sur_une_pile_de_livre_dehors_au_soleild6492.jpg" border="0"></center>

More research is needed, but in general, technology seems to be making us less thorough.

Most people tend to scan or skim pages of text and mostly click links, rather than engage in deeper reading that is usually done with paper text.

From students of similar reading skill, two groups were formed to read and test comprehension. One group was for paper text, and the other LCD text. Those doing LCD reading has lower comprehension scores of what they allegedly "read". The retention of information is not being done as much.

# Multitasking
<center><img src="https://storage.googleapis.com/steemimgimgs/2016/10/16/man-multitasking44fd9.jpg" alt="man-multitasking44fd9.jpg" border="0"></center>

Technology does help to make us better multitaskers in a sense, but at a cost.

The "infomania"  "always-on" culture has many tech distractions, like emails, texts, phone calls, etc.

A study of IQ tests while technological distractions were present, indicated an average reduction by 10 IQ points, compared to a quiet room. This seems to indicate a likelihood in general distractions to impair memory and concentration in testing, rather than it being a case for technology along. 

Certainly, the advent of more technology increased the amount of distractions in our lives, thereby increasing the amount of time in a day we are likely to be affected by distractions to perform our tasks.

Frequent multitasking shows "smaller grey matter density in the anterior cingulate cortex" where empathy and decision making takes place. I think this relates to how paying attention and focusing on something allows us to recognize it and empathize with it if need be. When we don't pay attention, ignore, we are cold, and don't really empathize.

# Navigation

Indeed, technology can change our brains when it comes to navigation like GPS. I mentioned that before in the [automation bias](https://steemit.com/cognitive-biases/@krnel/automation-bias-cognitive-biases-pt-6) post.

Taxi drivers who know the city they drive in by memory, have more posterior hippocampus grey matter. This improves their memory tasks for landmarks to find their way in their mental map. Although, their anterior hippocampus is reduced, making for poorer visual information recall.

Non-GPS users are similar, with more hippocampus grey matter for better memory recall.

All in all, technology does indeed affect how our brains process the environment, and therefore how we are going to act, behave and respond in that environment. Some of it is good, and some of it is bad. The more we are aware of the negative manifestations from the creations of our technology, the more empowered we are with that knowledge to find ways of counterbalancing those negative effects and further improve our lives.
