Please read the following case study and answer the questions

 

In a study of memory, Melina Uncapher and colleagues recruited 20 volunteer participants for a study of recall tests that involved the recall of features of a series of 100 words which the participants had been asked to memorise.

 

For the learning phase of the experiment, the participants were asked to memorise the 100 words. Next, while undergoing fMRI brain scans, the letters in one of the four quarters of a small screen. The screen was set out so that it was divided into four quarters. The words were written either in black or in a colour (red, green, blue or pink). For black words, the participants were required to determine whether the object would fit inside a shoebox. For coloured words, the participants were required to determine whether the object written in colour was a living organism.

 

Afterwards, the participants were tested for their recall of the words, their colour and in which quarter of the screen each of the words had been presented. The participants' answers were compared with the information gathered from the fMRI which had been conducted during the learning phase.

 

Results indicated that the parts of the brain which are involved with the identification of the colour (of the words). and location (which quarter of the screen) were more active when the participants had been specifically instructed to learn either the word colour or the word location. However, when they had been instructed to memorise all three word features (the word, its colour, and its location), the intraparietal sulcus was activated. The intraparietal sulcus is the fold in the brain which connects the upper and lower parts of the parietal lobe and which is thought to enable us to perceive different qualities of an object simultaneously, rather than one at a time. In other words, the research indicated that the intraparietal sulcus is important for memorising qualities of objects as a whole. 

 

Uncapher also reported that the hippocampus indicated some increased activity during fMRI scan phase. However, the study did not scan the participants' brains during the period when they were memorising the 100 words.
