Summary
Young adults struggle with the analog clock drawing test (CDT) due to decreased exposure to analog clocks. Caution is advised when using the CDT for cognitive screening in this demographic.
Area of Science:
- Cognitive Neuroscience
- Gerontology
- Psychometrics
Background:
- The clock drawing test (CDT) is a widely used tool for assessing cognitive function.
- Increased reliance on digital technology has reduced exposure to analog clocks.
- This shift may impact the performance of young adults on analog-based cognitive assessments.
Purpose of the Study:
- To evaluate the ability of young adults (18-30 years) to perform the clock drawing test (CDT).
- To determine if digital-native young adults can accurately draw and interpret analog clocks.
- To assess the suitability of the CDT for cognitive screening in this age group.
Main Methods:
- 80 participants aged 18-30 with self-reported normal cognition completed the CDT.
- Participants also performed tasks involving setting hands on a pre-drawn clock and identifying analog times.
- Data analysis focused on CDT scores and correlations between analog clock tasks.
Main Results:
- Approximately 25% of young adults scored below the expected range on the CDT.
- A moderate positive correlation was found between analog clock hand setting and time identification in a subset of participants.
- The majority of participants reported not wearing analog watches.
Conclusions:
- The clock drawing test (CDT) should be used with caution for cognitive screening in young adults (18-30 years).
- Alternative cognitive screening methods or modifications to existing assessments are recommended for this population.
- Further research is needed to understand CDT performance in young adults.

Longitudinal Research
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Cross-Sectional Research
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
