The amount of experimental studies about DID are limited, and few can support the diagnosis of DID. A study completed by Putnam (1984) found that the EEG activity (brain wave activity) in patients with DID were indeed different from one identity to the next. This means that if there exist only one identity, it shouldn’t be possible to have a different brain wave activity. A different study was done by Reinders and colleagues (2006) which examined cardiovascular reactivity to both neutral and traumatic memories to different alters. A neutral memory was shown to both the neutral id and the traumatic id, but neither of the heart’s response was anything significant. But when shown a traumatizing memory, the traumatic id showed significant emotional distress but not the neutral id. This result lead to the supposition that a certain alter may be created to protect the person from a traumatic memory, so that they can go on living their life without the horror of the
