Two Heads are Better than Two
We show that a Turing machine with two single-head one-dimensional tapes cannot recognize the set f x2x 0 j x 2 f0;1g and x 0 is a preex of x g in real time, although it can do so with three tapes, two two-dimensional tapes, or one two-head tape, or in linear time with just one tape. In particular, this settles the longstanding conjecture that a two-head Turing machine can recognize more langua...
متن کاملWhen Three Heads Are Better Than Two
The present study investigated the effects of both group size and heterogeneity in relevant math skill on collaborative problem solving. Overall, triads demonstrated better reasoning and more effective cryptarithmetic problem solving than dyads and singletons. Importantly, triads outperformed the best individuals in a nominal groups analysis. Triads were also better able than dyads to take adva...

متن کاملWhy two heads apart are better than two heads together: multiple mechanisms underlie the collaborative inhibition effect in memory.
Although a group of people working together remembers more than any one individual, they recall less than their predicted potential. This finding is known as collaborative inhibition and is generally thought to arise due to retrieval disruption. However, there is growing evidence that is inconsistent with the retrieval disruption account, suggesting that additional mechanisms also contribute to...
متن کاملPerceptions of randomness: why three heads are better than four.
A long tradition of psychological research has lamented the systematic errors and biases in people's perception of the characteristics of sequences generated by a random mechanism such as a coin toss. It is proposed that once the likely nature of people's actual experience of such processes is taken into account, these "errors" and "biases" actually emerge as apt reflections of the probabilisti...
