Memory implicit

The flip side of explicit memory is implicit memory. Implicit memory refers to things like skills and habits. When you drive from your office or school to your home every day, you are using your implicit memory to guide you. When you shoot free throws on the basketball court, it is your implicit memory that guides your actions. Long-term implicit memories are stored in various places in the brain the amygdala, cerebellum, or striatum.

A few studies have been performed with event-related potentials (ERP) to examine the cognitive effects of THC. In subjects viewing emotionally valenced words (neutral, negative, or positive), THC produced a behavioral decrease in recognition rate (Leweke et al. 1998). The ERPs showed the typical difference between old and new words (enhanced positivity for old words beginning 250 milliseconds poststimulus), and THC enhanced the positivity in response to old words. This counterintuitive dissociation between ERPs and behavioral indices was interpreted as a reflection of implicit memory processes underlying the ERP effect.

For human beings, two different memory categories have been introduced. According to Schacter, imphcit (or unconscious/unaware) memory is revealed when previous experiences facilitate performance on a task that does not require conscious or intentional recollection of those experiences. Explicit memory, in turn, is revealed when the performance of a task requires conscious recollection of previous experiences. These are descriptive concepts that are primarily concerned with a person s psychological experience at the time of memory retrieval. Accordingly, the concepts of implicit and expUcit memory neither refer to nor imply the existence of two independent or separate memory systems (Schacter 1987). As these two memory categories cannot be easily appHed to the situation in animals, they will not be further considered in this chapter.

A wide range of cognitive functions are affected, particularly memory, attention, motor skills, executive function and intelligence. In contrast, implicit learning appears to be unaffected (Danion et al., 2001). 

Episodic memory and learning, involving both explicit verbal and visual memory performance in contrast, recognition and implicit memory tasks appear to be spared.

Input Processing draws heavily on some kind of memory. That is, you need stored criteria of what is important in order for Input Processing to do its work. Much of this is implicit. 

Changes in continuity of memory over time—either an implicit feeling that continuity is present or an explicit checking of memory that shows current experience to be consistent with continuous memories leading up to the present, with gaps suggesting an altered state...
