An anagram is a word of the form WP where W is a non-empty word and P is a permutation of W . A vertex colouring of a graph is anagram-free if no subpath of the graph is an anagram. Anagram-free graph colouring was independently introduced by Kamčev, Łuczak and Sudakov and ourselves. In this paper we introduce the study of anagram-free colourings of graph subdivisions. We show that every graph ...

Previous research in motor learning shows that practicing variations of a task (variable practice) leads to better transfer than does repeatedly practicing the exact same task (repeated practice). In contrast, research on priming using verbal materials shows that performance on a test improves to the extent that the material at learning and test overlap. We tested whether variability in practic...

A sequence S is called anagram-free if it contains no consecutive symbols r1r2 . . . rkrk+1 . . . r2k such that rk+1 . . . r2k is a permutation of the block r1r2 . . . rk. Answering a question of Erdős and Brown, Keränen constructed an infinite anagram-free sequence on four symbols. Motivated by the work of Alon, Grytczuk, Ha luszczak and Riordan [2], we consider a natural generalisation of ana...

Anagram tasks are frequently used in cognitive research, and the generation of new scrambled letter combinations is a task well suited to a software solution. Most available programs, however, do not allow experimenters to generate new anagrams flexibly or to characterize existing anagrams using psycholinguistic criteria. They also do not provide detailed information on their source dictionarie...

This study is aimed at improving the students’ vocabulary achievement through anagram. was conducted by using classroom action research. The subject of this 2009/2010 ten grade students SMA Negeri 1 Pancur Batu which consisted 30 students. For collecting data, instrument used quantitative data (vocabulary test) and qualitative (diary notes, interview sheet observation sheet). Based on it found ...

Within the context of an interactive anagram-solving task, the present studies tested predictions about the role of cognitive anticipation in both source and item memory. After working in pairs to solve anagram problems, participants were surprised by a source-monitoring test focused on the source of solutions (self vs. partner, Experiment 1) or a standard recognition test focused on the soluti...

An insoluble anagram task [Zellner, D., Loaiza, S., Gonzalez, Z., Pita, J., Morales, J., Pecora, D., et al. (2006). Food selection changes under stress. Physiology and Behaviour, 87, 789-793] was used to investigate the proposition that chewing gum reduces self-rated stress [Scholey, A., Haskell, C., Robertson, B., Kennedy, D., Milne, A., & Wetherell, M. (2009). Chewing gum alleviates negative ...

Recent research on anagram solution has produced two original findings. First, it has shown that a new bigram frequency measure called top rank, which is based on a comparison of summed bigram frequencies, is an important predictor of anagram difficulty. Second, it has suggested that the measures from a type count are better than token measures at predicting anagram difficulty. Testing these hy...
