“…During ageing the proportion of 'know' to 'remember' responses increases [19][20][21], an effect which is consistent with the documented age-related decline in hippocampal volume and function [22][23][24]. 'Remember' and 'know' responses can also be differentiated pharmacologically by, for example, lorazepam [25] and alcohol [26]. In relation to studies of the glucose facilitatory effect, Sunram-Lea et al [27] reported that glucose preferentially increased the proportion of responses based on recollection, but had no effect on the proportion of responses based on familiarity.…”

Nutrition and Aging 3 (2015) METHODS:In this double-blind placebo-controlled cross-over study, 12 older participants (mean age = 69.33 ± 1.69 years) completed the remember-know paradigm both with and without a concurrent tracking task while recording event-related potentials (ERPs). RESULTS: Counter to predictions, glucose reduced overall accuracy. No treatment effects were found for proportion of Remember, Know and Guess responses, although there was a trend towards greater accuracy for 'Remember' responses following glucose. There was weak evidence for dissociation of drink effects on tracking with glucose being associated with preferential allocation of resources to 'Remember' over 'Know' responses. At P3 and F3 electrode sites, a significantly greater left parietal (LP) recollection effect and greater FN400 effect respectively were found for glucose. CONCLUSIONS: These findings do not support task effort modulation of the memory-enhancing effects of glucose. There was evidence of a greater glucose facilitatory effect for hippocampus-mediated LP recollection.

“…They might be restricted to certain kinds of perceptual e¡ects. In line with that possibility, Curran & Hildebrandt (1999) showed that remembering is greatly reduced by alcohol but that a level-of-processing e¡ect did not as a result then appear in know responses. That result too suggests that the appearance of the size congruence e¡ect in know responses was not simply due to the lower level of performance in the more impoverished encoding conditions, rather than due to the qualitative nature of the encoding.…”

Episodic memory is identi¢ed with autonoetic consciousness, which gives rise to remembering in the sense of self-recollection in the mental re-enactment of previous events at which one was present. Autonoetic consciousness is distinguished from noetic consciousness, which gives rise to awareness of the past that is limited to feelings of familiarity or knowing. Noetic consciousness is identi¢ed not with episodic but with semantic memory, which involves general knowledge. A recently developed approach to episodic memory makes use of`¢rst-person' reports of remembering and knowing. Studies using this approach have revealed many independent variables that selectively a¡ect remembering and others that selectively a¡ect knowing. These studies can also be interpreted in terms of distinctiveness and £uency of processing. Remembering and knowing do not correspond with degrees of con¢dence in memory. Nor does remembering always control the memory response. There is evidence that remembering is selectively impaired in various populations, including not only amnesic patients and older adults but also adults with Asperger's syndrome. This ¢rst-person approach to episodic memory represents one way in which that most elusive aspect of consciousness, its subjectivity, can be investigated scienti¢cally. The two kinds of conscious experiences can be manipulated experimentally in ways that are systematic, replicable and intelligible theoretically.

“…Testing will take place next day without the influence of alcohol so that the effects of alcohol on encoding will be tested independently from its effects on retrieval. Previous studies testing the effects of alcohol on false memories did not fully separate the encoding and retrieval phases of the experiment in terms of alcohol intoxication (Curran and Hildebrandt 1999;Mintzer and Griffiths 2001). Testing after a 24hour interval will in addition provide information about long-term priming for false memories, since no study using implicit measures has previously attempted a 24hour retention interval.…”
