The central executive directs attention and gives priority to particular activities. The central executive is the most versatile and important component of the working memory system. … Baddeley suggests that the central executive acts more like a system which controls attentional processes rather than as a memory store.
The central executive is the component of the working memory model that monitors incoming data, makes decisions and allocates the three slave systems to tasks.
The central executive is responsible for controlled processing in working memory, including but not limited to, directing attention, maintaining task goals, decision making, and memory retrieval.
The state executive consists of the Governor, the chief Minister, the Council of Minister and the Advocate General of the state.
The central executive is the subsystem of working memory that controls the flow of information between the three storage subsystems described earlier, the flow of information between the episodic buffer and long- term memory, and which part of the system is the current focus of attention.
Working memory is used to hold information online during the execution of other cognitive functions. According to the Baddeley and Hitch model (Baddeley & Hitch, 1974), working memory consists of two subsystems and a central executive.
Central executive: coding & capacity • The central executive has limited capacity. • The central executive can store any type of information.
This neuroscience research clearly shows that the frontal region of the cortex is the most active portion of the brain when people work on a wide variety of central- executive tasks. Furthermore, both sides of the frontal region play a role in most central-executive activities.
Which of the following is a true statement about the neuroscience research on the central executive? It is primarily controlled by portions of the frontal lobe. What is the serial position effect in memory research? The finding that people are best at remembering the first few and last few items on a list.
Emotions cannot be studied in nonhuman animals because there is no way to assess whether such animals have a subjective experience of emotions like humans do.
In another study, encoding was associated with left frontal activity, while retrieval of information was associated with the right frontal region (Craik et al., 1999).
Evaluation: Miller’s (1956) theory is supported by psychological research. For example, Jacobs (1887) conducted an experiment using a digit span test, to examine the capacity of short-term memory for numbers and letters.
Specification of Theory
Miller (1956) presented the idea that short-term memory could only hold 5-9 chunks of information (seven plus or minus two) where a chunk is any meaningful unit. A chunk could refer to digits, words, chess positions, or people’s faces.
eidetic memory. A person with hyperthymesia can remember nearly every event of their life in a lot of detail. … Those who have a superior eidetic memory can continue to visualize something they have recently seen with great precision.
Working memory is a multi-component system which includes the central executive, visuospatial sketchpad, phonological loop, and episodic buffer.
The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.
Studies also suggest that people with ADHD often have significant problems with working memory. Working memory is a “temporary storage system” in the brain that holds several facts or thoughts while solving a problem or performing a task.
– A Shallice and Warrington (1974) case study reported that brain-damaged patient KF could recall verbal but not visual information immediately after its presentation, which supports the WMM’s claim that separate short-term stores manage short-term phonological and visual memories.
Model of memory (MSM), which describes flow between. three permanent storage systems of memory: the sensory register (SR), short-term memory (STM) and long-term memory (LTM). • The SR is where information from the senses is stored, but. only for a duration of approximately half a second before it.
Since the executive functions are involved in even the most routine activities, frontal lobe injuries can lead to deficits in cognitive (thinking) skills, personality and social behaviour. Loss of ‘get up and go’. Problems with thinking ahead and carrying out the sequence of steps needed to complete a task.
They are: Working memory. Cognitive flexibility (also called flexible thinking) Inhibitory control (which includes self-control)
The inability to retrieve a memory is one of the most common causes of forgetting. So why are we often unable to retrieve information from memory? … According to this theory, a memory trace is created every time a new theory is formed. Decay theory suggests that over time, these memory traces begin to fade and disappear.
When the concepts are distinguished, eidetic memory is reported to occur in a small number of children and generally not found in adults, while true photographic memory has never been demonstrated to exist. … The word eidetic comes from the Greek word εἶδος (pronounced [êːdos], eidos) “visible form”.
