Cognitive Contemporary Study

Question 1

What is the cognitive contemporary study?

Answer 1

Sebastian & Hernandez Gill (2012)

Question 2

What was the aim?

Answer 2

• To analyse the developmental pattern of the phonological loop in children aged 5-17 years old. This involved
• To look at the decline of digit span in older people, including those with types of dementia: Alzheimer’s and fronto-temporal dementia.

Question 3

What was the research method?

Answer 3

Lab experiment: digit span task

Question 4

Who was the sample?

Answer 4

-570 volunteers aged 5-17 years from various schools in Madrid.

Question 5

What was controlled in the experiment?

Answer 5

-No participants had repeated a year, had learning difficulties such as in reading, writing or hearing, which created control of education and cognitive differences.

Question 6

What was the procedure?

Answer 6

-Participant’s were split into age groups: age 5-6, 9-11, 12-14 and 15-17 years.

Question 7

What was the procedure?

Answer 7

• Participant’s were split into age groups: age 5-6, 9-11, 12-14 and 15-17 years.
• P’s were tested individually in their break. Sequences of digits were read aloud, one per second.
• Each time a participant got the sequence right, another digit was added to increase the span and the participants tried again.
• They started with 3 sequences of 3 digits. The digit span measure was the number of digits in the sequence where they recalled at least 2 of the three sequences correctly.

Question 8

What was the procedure?

Answer 8

• Participant’s were split into age groups: age 5, 6-8, 9-11, 12-14 and 15-17 years.
• P’s were tested individually in their break. Sequences of digits were read aloud, one per second.
• Each time a participant got the sequence right, another digit was added to increase the span and the participants tried again.
• They started with 3 sequences of 3 digits. The digit span measure was the number of digits in the sequence where they recalled at least 2 of the three sequences correctly.

Question 9

What were the results?

Answer 9

Digit span:

• 5 years: 3.76
• 6-8 years: 4.34
• 9-11 years: 5.13
• 12-14 years: 5.46
• 15-17 years: 5.83

The data was compared with research done in 2010 which included 25 healthy older people were used to compare against 25 people with Alzheimer’s disease

Question 10

What were the results?

Answer 10

Digit span:

• 5 years: 3.76
• 6-8 years: 4.34
• 9-11 years: 5.13
• 12-14 years: 5.46
• 15-17 years: 5.83

The data was compared with research done in 2010 which included 25 healthy older people were used to compare against 25 people with Alzheimer’s disease and 9 people with fronto-temporal dementia.
