Sigmund Freud is famous for his psychoanalytic theory and despite modern criticism, he presciently realised that cognitive processes are unconscious.

Sigmund Freud is one of the most famous figures in psychology.

He is best known for the method of psychoanalysis, which is a set of psychological theories and methods used to treat neuroses.

Therapy using psychoanalysis aims to release repressed experiences and emotions from the unconscious in order to facilitate the healing process.

Sigmund Freud and psychoanalytic theory

Sigmund Freud’s theory is that psychological problems are rooted in the unconscious mind.

The symptoms of these disturbances are seen in the symptoms of mental illness.

Sigmund Freud believed that the process of bringing the repressed conflicts to consciousness helps a patient deal with them.

Sigmund Freud’s theories have been extremely influential, leading to expressions like ‘denial’, ‘repression’ and ‘Freudian slip’ entering everyday discourse.

Sigmund Freud thought the personality had three major elements:

• Id: the most basic drive for pleasure, satisfaction of desires and wants.
• Ego: tries to satisfy the desires of the id in the most socially acceptable way. Freud explained the id was like a horse and the ego its rider.
• Superego: upholds moral standards often gained from parents and society.

Freud’s patients

Sigmund Freud’s theories and treatments were based on case studies of patients he had treated and those he had discussed with other doctors using similar methods.

Some of the most famous of these were:

• Anna O., who had hallucinations, paralysis and speech problems.
• Little Hans (Herbert Graf) who had a phobia of horses.
• Dora (Ida Bauer) who lost her voice.
• Wolf Man (aka Sergei Pankejeff) who was depressed and dreamed of wolves.
• Frau Emmy von N. is described in detail below…

Methods of Sigmund Freud

The problem for Sigmund Freud’s method was that if the key to mental healing is in the unconscious, how can it be accessed?

So, Sigmund Freud had to develop a series of techniques that he thought could reveal hidden neuroses.

The interpretation of dreams

Freud thought that the interpretation of the dreams was the ‘royal road to the unconscious’.

While were are asleep, he though, ideas that we would normally repress come to the surface.

Since dreams often make little sense, they need interpretation — Freud and other practitioners of psychoanalysis need to work out what they mean.

Free association

Sigmund Freud used free association as another method to access the unconscious.

This often involved saying a word to the patient and asking them to respond with the first thing that comes to mind.

Fragments of the true repressed problem are supposed to emerge through this method.

Freudian slip

Sigmund Freud believed that aspects of people’s unconscious mental processes were revealed by slips in speech.

In other words, we sometimes say what we really mean by accident.

He thought there were accidents and that every behaviour had a meaning, if only it could be correctly intepreted.

Modern view of Sigmund Freud

The strange thing about Sigmund Freud is that, amongst psychologists, his stock is relatively low.

One of the main reasons his work is not considered ‘scientific’ is the apparent difficulty of testing his theories.

Actually there is plenty of scientific evidence for his most important finding – the cognitive unconscious – but it has taken some time to be acknowledged.

Indeed, Sigmund Freud made some startling contributions to psychology only accepted into the mainstream of academic research in the last few decades.

To really understand the revolutionary nature of Sigmund Freud’s work you need to do something for me: to forget you’ve every heard of him or his ideas.

Imagine travelling back to the 19th century and here is a smartly dressed young man looking at you with bright intelligent eyes and there is a pungent smell in the room of cigars.

The case of Frau Emmy von N.

Frau Emmy von N. was one of the earliest patients to be treated with the nascent techniques of psychoanalysis and psychoanalytic theory.

Frau Emmy suffered from a series of tics, some facial, the most obvious of which was a loud ‘clacking’ noise.

To Sigmund Freud the symptoms she showed were typical of hysteria and he soon set about treating her with his strange new methods.

And what strange methods they were.

He talked to her.

Talking to a patient?

What good could that do?

He hypnotised her and soon she began to speak of her frightening experiences – being a maidservant in an asylum, nursing her dying brother.

Then Sigmund Freud did something more unusual.

He let her give full vent to her emotion.

Later, after she had calmed down a little, she seemed better…

Freud’s interpretation

What then did these past events in Frau Emmy’s life signal to Sigmund Freud?

What was the connection to her current symptoms?

At this time Sigmund Freud had begun to develop a psychoanalytic theory that physical symptoms could be caused by thoughts not available to the conscious mind.

His treatment – the talking, the hypnosis, the hand on the forehead, the free association, the couch – all were designed to try and access this so-called ‘unconscious’ world, to find the root-cause of distress.

Once this root-cause could be identified and explained, Freud thought, the physical and psychological symptoms would be alleviated (Breuer & Freud, 1893).

The cognitive unconscious

It was in Freud’s work ‘Project for a Scientific Psychology’ (Freud, 1895) that he first laid down the radical (at the time) idea that cognitive processes are intrinsically unconscious.

We are effectively cognitive icebergs with most of our ‘thoughts’ occurring below the water line, out of conscious perception.

The fact that this idea is no longer considered radical is testament to the last few decades of research which have shown the importance of unconscious processes.

We now have abundant evidence for unconscious processes in the operation of memory, affect, attitudes and motivation (Westen, 1998).

And so, far from being unscientific and untestable, Freud’s theory of unconscious mental processes was incredibly prescient.

It laid the ground for some of the most important lines of research in psychology today.

Research that tells us more and more about what it means to be human.

Facts about dreaming including how to remember dreams, why we forget dreams and whether heavy or light sleepers remember more.

While we are asleep the brain is active all night long.

Both adults and babies are thought to dream for around two hours each night.

People have several dreams each night, but probably forget about 95 percent of them.

Here are 10 more fascinating facts about dreaming…

1. How to remember your dreams

Some people recall all kinds of dreams, others hardly anything.

Why the big difference?

Part of the reason that some people remember more of their dreams is that they wake up more in the night, even if only for short periods.

It is a fact about dreaming that we need to be awake to encode dreams into long-term memory, otherwise they are generally lost to the night.

So, to remember dreams, they need to be talked about, written down or reflected on immediately after waking.

If you don’t record them in some way then it will be harder to remember your dreams.

2. Light sleepers remember more dreams than heavy sleepers

Whether you remember dreams, then, depends on whether you are a light or heavy sleeper.

A brain imaging study has found those who recall more of their dreams have higher activity in the medial prefrontal cortex (Eichenlaub et al., 2014).

In addition, those who recalled most dreams showed greater activity in the temporo-parietal junction: this area of the brain is associated with attention towards things happening in the external world.

Together these two areas are very important in dream recall.

One of the study’s authors Perrine Ruby, explained:

“This may explain why high dream recallers are more reactive to environmental stimuli, awaken more during sleep, and thus better encode dreams in memory than low dream recallers.

Indeed the sleeping brain is not capable of memorizing new information; it needs to awaken to be able to do that.”

Intention and practice will also help if you goal is to try and remember your dreams.

3. Daydreamers are also night-dreamers

The overlap between waking and dreaming states was at the heart of the Matrix films.

Sci-fi aside, though, the film asked about the fact that when we’re awake, are we really awake or is this just another dream?

That’s all exciting philosophical stuff of course, but actually this has some neurobiological truth.

Neuroscientists have found that it is a fact that parts of the brain responsible for daydreaming while we’re awake are also responsible for our dreaming while we sleep.

Effectively the neural substrate responsible for dreaming may be a sub-system of that responsible for our waking lives.

“…dreaming may be the quintessential cognitive simulation because it is often highly complex, often includes a vivid sensory environment, unfolds over a duration of a few minutes to a half hour, and is usually experienced as real while it is happening.” (Domhoff, 2011)

4. Some people cannot dream

Some say that they don’t have dreams, but in all likelihood they do, it’s just that they don’t remember their dreams because they are heavy sleepers.

It is a fact about dreaming, though, that some genuinely cannot dream.

Often as a result of brain damage from strokes, these patients can be awoken repeatedly during the night and asked about their dreams: they claim never to be dreaming (Bischof & Bassetti, 2004).

5. The purpose of dreams

Of course we don’t know what dreams are for so there is no ‘fact’ here.

It could be that dreams have no purpose, but are merely distracting by-products of losing consciousness in the particular way we do when we sleep.

Being human, though, means searching for explanations, so there’s no shortage of theories about what dreams are for.

They may be for testing out ideas, they may be for consolidating information, they may allow us to work on problems while we sleep, or they may be a way of getting rid of all the emotions we’ve built up during the day.

Which you believe probably has less to do with science than your own personal preference.

So, believe whatever makes life more fun for you!

6. It is not a fact that dreaming only occurs in REM sleep

Since the 1950s it’s been thought that dreaming is only associated with the so-called ‘Rapid Eye Movement’ portions of sleep, which make up around 20-25 percent of total sleep-time.

But this idea has now been challenged.

Studies have found that sometimes when people are awakened from REM sleep they report no dreams.

And, sometimes when awakened from non-REM sleep they do report dreams (e.g. Nielsen, 2000).

Although much of our dreaming is done in REM sleep, some is probably also done in non-REM sleep.

7. People everywhere dream about the same stuff

A study of 50,000 dream reports by US psychologist Calvin S. Hall and colleagues found that there are remarkable similarities in the way people dream all around the world:

• Dreams are usually phantasmagoric: people, places, events and objects tend to merge into one another.
• The most common emotion experienced in dreams is anxiety and negative emotions are much more prevalent than positive.
• The vast majority of people dream in colour–if you watched monochrome TV growing up, though, you’re more likely to dream in black-and-white.
• Only around 10 percent of dreams are sexual in nature, although the percentage is higher amongst adolescents.

8. The meaning of dreams

Dreams mean nothing.

That is not so much one of the facts about dreaming, more that I personally don’t believe dreams mean anything in the sense that most people understand this question.

But I’m in the minority, as demonstrated by a study which found that 56 percent of Americans endorse the Freudian view of dreams, in that they reveal deep psychological truths about the self (Morewedge & Norton, 2009).

Indeed this may even be an underestimate of how much store people put by dreams.

Morewedge and Norton’s study found that the majority of people think their dreams will influence their waking life, often more so than a similar waking thought.

So apparently I’m wrong: dreams mean a lot to people–even if it’s only because of the importance people ascribe to them.

9. Recording a lucid dream

Recording what happens in the brain during a particular dream is hard.

You can put people inside brain scanners while they’re asleep and then ask them afterwards what they dreamed about, but the problem is they don’t know when they dreamed it.

So it ends up being tricky matching up the brain imaging results with a particular dream.

One solution is to use lucid dreamers.

These are people who have trained themselves to be aware of when they are dreaming and who can also take control of their dreams.

A recent study of facts about dreaming which used lucid dreamers this way found significant overlaps between the activity in the brain during wakefulness and during sleep (Dresler et al., 2011).

One of the authors, Michael Czisch, explained:

“Our dreams are therefore not a ‘sleep cinema’ in which we merely observe an event passively, but involve activity in the regions of the brain that are relevant to the dream content.”

10. Do blind people ‘see’ in their dreams?

Have you ever wondered if blind people can see in their dreams?

This is one of the facts about dreaming that blind people get asked a fair amount.

Here is Youtube star, radio presenter and ‘blind film critic’, Tommy Edison, explaining the answer:

Studies back this up, finding that people who never had sight or who lost their sight before they were five do not dream visually.

.

People tend to think of daydreaming and letting the mind wander as a waste of time.

How wrong they are.

New research suggests daydreaming could be key to success and higher creativity.

Professor Moshe Bar, who led the research said:

“Over the last 15 or 20 years, scientists have shown that — unlike the localized neural activity associated with specific tasks — mind wandering involves the activation of a gigantic default network involving many parts of the brain.

This cross-brain involvement may be involved in behavioral outcomes such as creativity and mood, and may also contribute to the ability to stay successfully on-task while the mind goes off on its merry mental way.”

For the research, neuroscientists stimulated the frontal lobes electrically.

Professor Bar explained:

“We focused tDCS [electrical] stimulation on the frontal lobes because this brain region has been previously implicated in mind wandering, and also because is a central locus of the executive control network that allows us to organize and plan for the future.”

With the electrical stimulation people reported more daydreaming and mind wandering.

They also performed slightly better on a task they were given to do.

Professor Bar said:

“Interestingly, while our study’s external stimulation increased the incidence of mind wandering, rather than reducing the subjects’ ability to complete the task, it caused task performance to become slightly improved.

The external stimulation actually enhanced the subjects’ cognitive capacity.”

Previous studies have linked “on-task” mind wandering or daydreaming with increased performance.

As I explained in the previous post:

“Daydreaming and mind-wandering can have positive effects on mental performance in the right circumstances, a new study finds.

It used to be thought that when people are trying to solve puzzles, they perform best when the mind wandering part of the brain — called the ‘default network’ — is relatively inactive.

This makes sense given that ‘off-task’ thinking is likely to distract our focus.

In contrast to other research, though, a new study suggests the default network can sometimes help with tasks that require focus and quick reactions.”

The study was published in the journal Proceedings of the National Academy of Sciences (Axelrod et al., 2016).

Continuing the series on unusual research in psychology we search for proof of dream telepathy, a search which has thrown up some controversial findings and an experiment during a Grateful Dead concert.

For a few minutes after waking, my mind is filled with the alien imagery of dreams. Perhaps these dreams contain the roots of my neuroses? Or perhaps they are just the random flotsam of a brain unhooked from its body. Or perhaps they are something more intriguing — could they be a window through time and space itself?
