In 1819 few Britons believed in free trade but by 1885 it had become the common sense of the nation and Britain had built an imperial system around it. How did that happen?

How did an English state torn apart by sectarian conflict, civil war and a revolution in the late seventeenth century become the most powerful in the world by 1819?

Section 6.1 considers the brain regions associated with typical forgetting, which can be attributed to a lack of attention during encoding. In Section 6.2, the brain mechanisms underlying retrieval-induced forgetting are considered, which is when retrieval of one item (e.g., the word ‘banana’) has an inhibitory effect on related items (e.g., the word ‘orange’) and increases the rate of forgetting for these items. The brain regions associated with a related process called motivated forgetting, which is an increase in the rate of forgetting for items that one intentionally tries to forget, is then considered. In the next two sections of the chapter, two types of memory distortion are considered: false memories (i.e., memories for information that did not occur) and flashbulb memories (i.e., seemingly picture-like memories for very surprising and consequential events). It has been argued that long-term memory failure reflects an adaptive memory system that works well.

Section 2.1 reviews the behavioral measures that allow for the interpretation of brain activation results. Section 2.2 discusses techniques with high spatial resolution, such as fMRI, which is the most popular method. Section 2.3 focuses on techniques with high temporal resolution, such as ERPs. ERPs measure voltages on the scalp that directly reflect the underlying brain activity. In Section 2.4, techniques with excellent spatial resolution and excellent temporal resolution are described, including combined fMRI and ERPs, as well as recording from patients with electrodes implanted in the brain for clinical reasons. Section 2.5 considers evidence from patients with brain lesions and cortical deactivation methods such as TMS. Both methods have limited spatial resolution and poor temporal resolution; however, they can assess whether a brain region is necessary for a given cognitive process. In Section 2.6, the spatial resolution and temporal resolution of the different techniques are compared.

The noun “dynamics” entered the English language in the eighteenth century, when natural philosophers, following the lead of Isaac Newton, began thinking of motion in terms of applied forces and the resulting accelerations. In 1788, the New Royal Encyclopaedia contained the definition, “Dynamics is the science of moving powers; more particularly of the motion of bodies that mutually act on one another.” This is still a useful definition. For the purposes of this book, we can define dynamics as the study of objects that move while interacting through mutual forces.

How did new forms of mass politics and culture that included and gave voice to all men and women finally develop in Britain between 1885 and 1931?

Britain remained the world’s superpower in 1931, so how did it lose its Empire, become dependent upon the USA and reimagine itself as a European nation by 1976 and how did Briton’s respond?

A gravitationally bound two-body system (if the two bodies are spheres of constant mass) shows simple periodic motion. We have seen that a three-body system, even if we install restrictions for computational simplicity, can show a rich variety of behaviors. Tadpole orbits, horseshoe orbits, and ZLK oscillations are just a sampling of what can happen.

This chapter highlights the cognitive neuroscience techniques that have been employed in the past and the techniques that will be employed in the future. Section 12.1 describes the similarities between fMRI and phrenology, a pseudoscience from about two centuries ago in which protrusions of the skull were associated with behavioral characteristics. In Section 12.2, fMRI is directly compared to ERPs. Section 12.3 discusses research investigating brain region interactions. This type of research has only recently started to be conducted and involves brain activity frequency analysis or modulating one brain region and measuring how that changes activity in another brain region. Section 12.4 provides an overview of the field of cognitive neuroscience in the future. The final section shines a spotlight on the dimension of time. To date, temporal processing in the brain has received less attention than spatial localization. However, time is the future of the cognitive neuroscience of memory.
