Memory long term

Decision making may involve calculations, reference to procedures and past experience, and other demands on long-term memory. This contributes further to the overall mental workload. From the HF/E perspective, many errors are likely to arise from information processing overload, essentially from the mismatch between demands and capabilities. Information-processing demands can be reduced by the provision of information in the form of job aids such as flow charts or decision trees. 

Often referred to as short-term memory loss , this form of amnesia results in the inability to transfer new events to long term memory. The sufferer will still be able to recall older memories but will not be able to remember recent events once attention has been switched to something else. 

The main disturbance in inhalant intoxication delirium is a reversible decrease in the level of consciousness and awareness of the environment, which includes an inability to focus, sustain, or shift attention. The intoxicated person is confused and easily distracted by irrelevant stimuli and difficult to engage in a meaningful conversation. He or she may also exhibit prominent disorientation, short- and long-term memory deficits, language disturbances, and perceptual disturbances that may include illusions and hallucinations. Other prominent features associated with inhalant intoxication delirium are... 

Adenylyl cyclase in learning and memory. The cAMP-signal transduction cascade has been demonstrated to play a role critical to the formation of long-term memory in both cellular models and in animals. The specific adenylyl cyclases involved are being identified by current research. In AC1 mutant mice there is a partial disruption of long-term potentiation (LTP), a cellular model of...

As the digging task relies upon external motivation, investigators should be careful not to misinterpret the results. For example, if different strains of mice spend different amounts of time digging in the CS+ during the test phase of the experiment, this should not be interpreted to mean that one strain has learned more than another strain (Schellinck et al. 2001). It is possible that the different strains are more sensitive to food restriction, however mild, or have different levels of activity. Both factors could lead to increased digging. With this caveat, the task is very useful for assessing acuity and long-term memory.
