Psychologists like to claim that Psychology is a science, yet, until now, the discipline has lacked any real scientific laws, has had no overarching scientific paradigm and has been blighted by poor replicability of research, all of which have dogged the discipline. Attempts to place Psychology under a single scientific umbrella, e.g. Behaviourism, Cognitivism, Biological Science, Social Science or Human Science, have all failed for a host of reasons.

When we sleep badly with unwanted awakenings, we are ‘out of sorts’, grumpy or miserable and our ability to perform is diminished. Why these phenomena happen in the way that they do is almost a complete puzzle. One theory suggests that sleep enables the brain to reset neuronal plasticity to a regulated set range.1 Many theories have been proposed, but none is generally accepted.2 One thing that we do know is ...
