I was thinking about this phenomenon today. Digital clocks are so common now that I don't often need to read an analog one, much less in a hurry. I worry that I'm losing the ability to do so. (The worry is a little bit because I might still need it at some point, and much more because being able to quickly read analog clocks makes me feel like a grown-up.) In particular, when I am called upon to read one, I'm embarrassed by how long it takes me to do so. It's only several seconds, but that's enough to make it clear to anyone watching that I had to stop and think about it.
But then I caught myself, and thought, wait a moment. Am I actually much slower at this than I used to be? Or is reading an analog clock really just a noticeably slower action than reading a digital one? This is intuitively plausible; it has more mental steps. Rather than comparing my current analog-clock-reading speed with a previous one (which I don't really remember), I'm comparing it to my digital-clock-reading speed, which doesn't make sense. I was going to ask how you'd design an experiment to test this. Then I remembered that not everyone is young enough to have to speculate about what it's like not having mostly digital clocks around. :P So if you're old enough to have significantly more practice reading analog clocks than digital, how long does it take you to read one? Is it noticeably longer than reading a digital clock? If you aren't, and have a significantly different experience from mine, I'm interested in that too.
I'm 43. I grew up with analogue clocks and a few early digital ones (this was the 1970s). As a child, I had a toy which had a clock face with minute and hour hands, and a mechanically-linked display of the time the hands were indicating, to a five-minute resolution - it didn't actually look like this, but that'll give you the idea.
I seem to think of an hour as divided into twelve five-minute parts, each of which divides into five individual minutes. If I look at a digital display of the time (e.g. looking at the clock at the top of my netbook screen just now), I process it as a certain way around a circular sixty-minute track. It was 4:55pm just now, so I visualised a minute hand in the last segment before the hour.
I stopped wearing a watch in 1996 as it was simply annoying me. I still wanted to know what time it was, but wearing a watch annoyed me more. I now tend to use my phone as a watch. When I did wear a watch, I had one for a while that had hands and a digital display, which I liked a lot - glance quickly at the hands, or look at the digits for precision.
I haven't measured if analogue is quicker, but it feels easier. Culturally comforting, in some way.
Huh. For me it's the opposite. I always find it easier to glance at my wristwatch than to dig in my pocket for my phone. Part of it is that I keep my phone off most of the time, and because I hate purses/briefcases/etc. there's always lots of things in my pocket blocking the phone.
