Previous research has shown that heavy users of ecstasy (MDMA) may suffer impaired cognitive functioning, and the present study set out to investigate whether such impairment might also be found in light users or ex-users of MDMA. Sixty subjects, comprising 20 current light users, 20 ex-users, and 20 non-users of ecstasy, were tested on an extensive battery(More)
Five months after the Athens earthquake of September 1999, 178 children from three districts of Athens at increasing distances from the epicenter were administered questionnaires to identify symptoms of post-traumatic stress disorder (PTSD), anxiety and the extent of personal threat experienced. It was found that PTSD and anxiety symptoms were significantly(More)
It has recently been suggested (Anderson, 2003) that forgetting is an adaptive process arising from successful inhibition of unwanted items, rather than arising from a failure of the memory system. This inhibition process is thought to make use of retrieval-induced forgetting (RIF). In the present study, individual susceptibility to RIF was measured in a(More)
A test of verbal recognition, yielding separate scores for semantic and acoustic distractor errors as well as a simple recognition score, successfully discriminated between various groups of brain-damaged, depressive, and normal subjects in a sequence predictable from their pathology. However, the profile of distractor errors was similar for all groups(More)
Thirty-eight patients suffering from severe depression were given a course of ECT (Electroconvulsive therapy) in one of three waveforms. These were high-energy sine wave (HS), high-energy pulse (HP), and low-energy pulse (LP). Patients were assigned to one of these treatments on a double-blind basis. The patients were given a battery of memory tests before(More)
Retrieval-induced forgetting (RIF) refers to the finding that the retrieval of a memory trace suppresses the retrieval of rival memory traces, and there is evidence that RIF reflects the effects of cognitive inhibition. The Attentional Control Theory (ACT) postulates that cognitive inhibition will be impaired by a high level of state anxiety, but the effect(More)
