Multiple Trace Theory
It argues that the hippocampus is indeed involved in new memory formation and integration and consolidation of new memories. However, this theory states that the memories are never completely independent of the hippocampus. Rather, each time a memory is recalled, the hippocampus resets the memory to a different part of the brain, creating a new memory. However, the hippocampus keeps a 'trace' of the last memory, forming a richly detailed 'master copy' which remains in the hippocampus.

Instrumental
What type of hypnosis research involves hypnosis can be used to monitor clinical conditions like delusions in a controlled and reversible environment

Delusory Suggestion
What type of hypnotic suggestion?: Suggestions involve the invoking of hallucinations or delusions through suggestions. This is the most difficult type of suggestion, and is only effective on subjects who are very hypnotisable and susceptible to hallucination or delusion. For example, in a state of hypnosis, the hypnotist may suggest that there is a mosquito buzzing around the room, and then lands on the subject to bite them. A subject who has been successfully hypnotised will feel this experience both through audition and tactile sensation.
Posthypnotic Suggestion
What type of hypnotic suggestion?: involves the hypnotist suggesting that after hypnosis, the individual will forget certain events that have occurred in the past or during the hypnosis. This is only effective in individuals who are highly hypnotisable.
Challenge Items
What type of hypnotic suggestion?: suggestions which involve the hypnotist suggesting a particular state of affairs, and then challenging the subject to do the opposite to what is occurring. For example, the hypnotist may tell them that their eyes are tightly shut, and then challenge them to open their eyes.
Ideomotor
What type of hypnotic suggestion?: the hypnotist suggests an experience related to movement. For example, the hypnotist may ask the patient to hold our their hand, and then suggest that their hand becomes too heavy to hold up. This is the easiest type of suggestion, and it involves the translation of thoughts into actions.

Frontal Lobe
Which lobe of the brain is affected in retrieval failure?
Synaesthesia Congruency Task
Which objective measure of synaesthesia is this?: Based on the logic of the stroop effect You can test for what colours a synaesthete sees for certain letters You then give them their letters back in colours which DO NOT MATCH the colours they normally associate with them If synaesthesia is involuntary, then it will take longer for synaesthetes to read back the letters in the wrong colour • This is the Synaesthetic Congruency Affect • And this is an objective measure for synaesthesia
