2.7 Summary

  • Behaviourism proposes that all behaviour is learned and maintained by its consequences. It does not theorise about ‘mental events’.

  • Classical conditioning describes how reflex behaviours can become associated with neutral stimuli in the environment.

  • Operant conditioning describes how the incidence of freely occurring behaviours can be increased or reduced as a result of the incidence of pleasant and unpleasant consequences f

Torsional energy can be taken up by alternative DNA conformations

The energy introduced into DNA by twisting has great potential as a regulatory mechanism, since the free energy can be stored in a variety of different high-energy conformations along the chain.

3.5 Natural selection

Darwin summarised his theory of natural selection in the introduction to The Origin of Species as follows:

As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life

4.5 Torture

The question of torture is also raised in the play. Herrenvolk claims that he does not do the torture; it is some Uzbekistan outfit that does it. He actually gives them a justification by saying, in a rather glib way, that it is a lot easier to open a human being than an encrypted laptop. Of course, the question is, is it ever ‘right’ to exploit this as a means of finding things out? I suspect most of us would say ‘no’.

3.4 Specialisation within language areas: brain scanning

Is there any evidence from the undamaged brain that the view derived from aphasia is indeed correct? The most useful methodologies here use either PET or functional MRI (fMRI) scanning to establish which parts of the brain are active in particular tasks. The difficulty is that a standard linguistic task, such as understanding a sentence's meaning, involves phonology and syntax and semantics, and thus is not helpful when trying to tease out which of these subtasks happens in which areas.

3.3.1 Making connections between the known and the new

Rogoff builds on the concept of intersubjectivity to emphasise the shared history, communicative strategies and purposes in a learning relationship that facilitate joint focus and effective collaboration. Laboratory studies of teaching, learning and problem solving are often based on a task or skill that is quite new to participants. In everyday life, such complete novelty is rare. Encountering a new situation, one of the first things that teachers and learners try to do is to make sense of i

1.6 Fibrous proteins

Most of the proteins described so far have been globular proteins. There are, however, some distinctive features that characterise fibrous proteins and we present here a general overview of these. Elongated fibrous proteins frequently play a structural role in the cell. They do not readily crystallise but tend to aggregate along their long axis to form fibres. X-ray diffraction studies of these fibres, in contrast to analysis of protein crystals, provides only very limited information on the

2.7 The 'salt' in seawater

The difficulty with having so much of the Earth's water locked up in the oceans is summed up poetically by Coleridge's 'Ancient Mariner', becalmed on board ship in the doldrums, beneath a blazing Sun.

Water, water, everywhere,

And all the boards did shrink;

Water, water, everywhere,

Nor any drop to drink.

(Samuel Taylor Coleridge, The Rime of the Ancient Mariner, 1797-8)
