Is Multitasking More Efficient?

Is Multitasking More Efficient?:

"New scientific studies reveal the hidden costs of multitasking, key findings as technology increasingly tempts people to do more than one thing (and increasingly, more than one complicated thing) at a time. "

"The researchers say their results suggest that executive control involves two distinct, complementary stages: goal shifting ("I want to do this now instead of that") and rule activation ("I'm turning off the rules for that and turning on the rules for this"). Both stages help people unconsciously switch between tasks."

"Rule activation itself takes significant amounts of time, several tenths of a second -- which can add up when people switch back and forth repeatedly between tasks. Thus, multitasking may seem more efficient on the surface, but may actually take more time in the end."

"Understanding executive mental control may help solve "fundamental problems," says Meyer, "associated with the design of equipment and human-computer interfaces for vehicle and aircraft operation, air traffic control, and many other activities in which people must monitor and manipulate the environment through technologically advanced devices.""

This article, and the study that goes with it, seems a bit slanted if you ask me. When I was first told about this piece a sweeping statement was made like: "Oh, kids aren't multitaskers! Ha, ha! They're wasting time... Haven't you seen the new study?" Yet the study only proves that we polychrons are wasting milliseconds... yes, "tenths of a second"... as we switch from task to task. I think the overall assumption or argument that says multitasking wastes time needs more than just milliseconds to convince me.

However, the idea that we can cut out even those few tenths of a second by better understanding our executive controls and innovating our UI now becomes even more appealing to me. I mean... isn't that the idea behind the dashboard widget and the firefox plugin? To bring the functionality of one thing to another and yet keep the same interface?

Quechup to the times...

Quechup.com is one of the newest social networking sites to pop up and has made quite an impact on me, albeit in a negative way.

Earlier today I was invited to join the network. I accepted the invite and decided to make a profile and check it out. During the set up it said it would look though my gmail address book and see who else was on Quechup. After it got done thinking, there were four check boxes. It said "would you like to be friends with these people". Since they were already on Quechup, I clicked yes.

Apparently when I clicked yes, Quechup sent emails to EVERYONE ELSE in my address book inviting them to be my friend on the Quechup site. (For more of my personal reactions to this incident, check out my personal blog at www. anthonyfontana .vox.com). This is a familiar process for those who use facebook. However, without one additional page asking if I'd like to invite everyone by email.

This incident (and of course, a PAID networking site) got me thinking about the amount of trust we put into social networking sites. It may have said somewhere on that page "would you also like us to spam everyone in your address book with an invite to our site?" But my intuitive reaction was to click yes, invite the four friends you have checked. There was a level of trust there, built by similar interfaces on other sites, that Quechup took advantage of.

Now comes the kicker. During my profile setup, it asked me questions about height, eye color, as well as whether or not I live with my children. However, when I tried to enter simple information in the text box, things like "I'm an educator," or "I use Second Life", an error message appeared informing me NOT to put that sort of info on their site due to "identity theft on social networking sites." It then gave me the same error message when I tried to enter such things as "art, movies, and music" as interests.

Here, Quechup is trying to build a false level of trust by insisting that they are protecting me, meanwhile collecting a lot more information than other social networking sites have. Was I willing to give up the info... sure. Will I now? I don't think so.

How can we establish trust with websites that promote trust in relationships? What role does intuitive interface play in our expectations of service? What happens to our trust when these expectations are not met or even worse broken?
