Example of the Sternberg memory-scanning task (figure adapted from Plomin & Spinath, 2002) [57] Saul Sternberg (1966) devised an experiment wherein subjects were told to remember a set of unique digits in short-term memory. Subjects were then given a probe stimulus in the form of a digit from 0–9. The subject then answered as quickly as ...
To learn more about this difference, brain activation during a mental rotation task was studied. In 2012, a study [26] was done in which males and females were asked to execute a mental rotation task, and their brain activity was recorded with an fMRI. The researchers found a difference of brain activation: males presented a stronger activity ...
The task requires the subject to connect 25 consecutive targets on a sheet of paper or a computer screen, in a manner to like that employed in connect-the-dots exercises. There are two parts to the test. In the first, the targets are all the whole numbers from 1 to 25, and the subject must connect them in numerical order.
Whether able to perform the task well or not the ventrolateral prefrontal cortex is highly involved. Corsi blocks tasks with a normal forward order requires support from the visuospatial sketch pad, but not from the phonological loop. When the sequence to be recalled becomes longer than three or four items, central executive resources are used [20]
These interact to cause acoustic errors in serial memory tasks by adding in acoustic confusability amongst the items. [9] Processing in atypical individuals. It has been found that when mental age is equated, there is no difference in performance on serial memory tasks for children with autism. This is an important finding as serial memory ...
Specificity of processing describes the increased recall value of a stimulus when presented in the method with which it was inputted. For example, auditory stimuli (spoken words and sounds) have the highest recall value when spoken, and visual stimuli have the highest recall value when a subject is presented with images. [6]
The primary form of fMRI uses the blood-oxygen-level dependent (BOLD) contrast, [4] discovered by Seiji Ogawa in 1990. This is a type of specialized brain and body scan used to map neural activity in the brain or spinal cord of humans or other animals by imaging the change in blood flow (hemodynamic response) related to energy use by brain ...
Brain-reading or thought identification uses the responses of multiple voxels in the brain evoked by stimulus then detected by fMRI in order to decode the original stimulus. . Advances in research have made this possible by using human neuroimaging to decode a person's conscious experience based on non-invasive measurements of an individual's brain activit
