ESP research - Ganzfeld studies

We introduced the Ganzfeld technique for studying ESP (extra-sensory perception - perceiving another person's thoughts without the use any scientifically understood sense, or 'remote viewing') at the end of term, trying out some free-association Ganzfeld.

Here is a not-very-serious video illustrating what the procedure involves.

Read about Ganzfeld-induced hallucinations here.

The Wikipedia article on Ganzfeld is very helpful.

You need notes on two studies by our next lesson on Thursday 23rd February - Sargent and Soal-Goldney (the former is in the Ganzfeld/PK section of your textbook, the latter is in the section before on Scientific Fraud.

A homework essay is due by the end of next week - for submission through Edmodo if you can manage that.

"To what extent has the issue of scientific fraud damaged the credibility of research into ESP and psychokinesis?" 9 + 16 marks.

Anomalistic Psychology - Intro and Psychokinesis research

Over the last four lessons we have introduced our Anomalistic Psychology topic and looked at research into PK - psychokinesis or 'psychic action' - moving or manipulating objects with will / mind power alone.

Here is the presentation from the introductory lesson.

You should have definitions of the following:
  • Anomalous experience
  • Paranormal
  • Parapsychology
  • Pseudoscience
  • Anomalistic psychology
  • ESP
  • Ganzfeld
  • Telekinesis
  • Psychic
  • Psychic mediumship
  • Psychic healing
  • Near death / out of body experience
The first section of the specification is as follows:

The study of anomalous experience
  • Pseudoscience and the scientific status of parapsychology
  • Methodological issues related to the study of paranormal cognition (ESP, including Ganzfeld) and paranormal action (psychokinesis)
We began this by looking at what makes science 'science' - in particular replicability, falsifiability, objectivity, experimental method and a consistent paradigm - you should be able to explain these with examples. Parapsychology is a pseudoscience (false science) because it fails on one or more of these, but then so does a lot of the rest of psychology! This makes these ideas helpful for evaluating other topics.

Here is a long presentation on pseudoscience, and here is a short one on science.

Macro PK research by parapsychologists has involved attempts to prove that spoon-bending and other similar 'powers' are real. The key issue here is one of falsifiability - if researchers are looking for evidence to confirm that an effect is real, rather than trying to falsify the claim, then it is easy for them to be taken in.

Micro PK involves influencing RNGs (random number generators), 'electronic coin flippers' and other electronic devices that produce random data. Research in this is more respectable, with some research apparently showing very significant results, albeit for very small effects.

Here is a presentation on PK.

You need notes on Walter Levy Jr. research with aparently psychokinetic rats (this is a good example of scientific fraud - deliberate cheating by a researcher) as well as the PK section of your textbook. Learn these for a test next Thursday (9th February).

Psychological therapies for schizophrenia

Today we watched a video on Freud and explored why he believed psychoanalysis wouldn't work for schizophrenia.
In psychoanalysis, the therapiest creates an alliance with the patient in order to discuss the patient's problems. The client transfers emotions originally associated with one person (usually a parent) on to the therapist - this is transference. Freud thought that this wasn't possible for a schizophrenic.
Later therapists have attempted to use psychoanalysis for schizophrenia with not very convincing results, and it certainly is no more effective than drugs.
The powerpoint is here.

Biological treatments for schizophrenia

Recently we covered the biological therapies for schizophrenia - drugs & ECT. The powerpoint is here. Prior to the discovery of antipsychotics in the 1950s there was no effective treatment for schizophrenia. Insulin treatment and ECT were used, but largely as methods of control rather than treatment. ECT is no longer used for schizophrenia because of the risks associated with it (but is occasionally for severe depression), but it is interesting to study for historical interest and because of the inherent ethical questions it raises. Don't worry about the biochemistry of how the antipsychotics work - their overall effect is to lower dopamine levels. Tardive dyskinesia is a worrying side effect, which can be irreversible.
