3G is a fixed speed (5-15mbit/s) and has almost total coverage (as opposed to other services such as EDGE, which is slower and has spotty coverage at best). Wifi network speed can be 11 mbit/s (802.11b), 54 mbit/s (802.11g), or 600 mbit/s (802.11n), depending on the router. However, the internet connection will more likely be tied to the internet connection of the router rather than the actual network strength - ie you may be connected to an 802.11g network, but only be able to browse the web at 4mbit/s because that's the speed of internet connection that is available to the router. The internet connection may also be capped by a poor choice of router - ie, you may connect to a wifi network with a 50 mbit/s internet connect, but be restricted to 11 mbit/s because it's an 802.11b router and not 802.11g or 802.11n. Either normally has around the same speed, but you would normally be able to get a better connection to a Wifi signal than a 3G signal, since 3G connects to either a phone mast or a satellite, and connecting to a Wifi signal normally just means connecting to a router a few metres away from you.

The biological theory of emotion focuses on the physiological responses that accompany emotions, such as changes in heart rate or hormone levels. In contrast, the cognitive theory of emotion emphasizes the role of thoughts and interpretations in determining emotional experiences. While the biological theory emphasizes the automatic and innate nature of emotions, the cognitive theory suggests that emotions are influenced by individual perception and interpretation of events.
The answer depends on what you wish to compare and contrast it with.
