9.1 Introduction

Psychophysics is the oldest field of the science of psychology. It stems from attempts in the nineteenth century to measure and quantify sensation. It attempts to quantify the relationship between a stimulus and the sensation it evokes, usually for the purpose of understanding the process of perception. Historically, psychophysics has centred around three general approaches. The first involves measuring the smallest value of some stimulus that a listener can detect – a measure of sensitivit

Introduction

‘Freedom’ can mean many different things. Here we're concerned with political freedom. Isaiah Berlin distinguished between a concept of negative freedom and a concept of positive freedom. You will examine these concepts and learn to recognise the difference between freedom from constraint and the freedom that comes from self-mastery or self-realisation.

The following material is taken from the book Arguments for Freedom ‘1999’ authored by Nigel Warburton of The Open Unive

Season 3 – Lesson 29 – Coffee Break Spanish
Coming up in this episode:

In this week’s episode, Alba and Mark are en la cocina, making a Spanish tortilla. The episode is slightly different from our usual episodes as the audio was recorded live in the kitchen rather than in the studio. There’s no “Act II” this week as the conversation follows the entire process of making the tortilla.

Please note that lesson 29 of Season 3 was originally known as lesson 329 of Coffee Break Spanish. We have renumbered

6 Population growth

Earlier it was stated that three factors check population growth. These are predation, disease and insufficient food supply. For much of our history, our ancestors’ numbers were indeed limited by wars, disease and famine. The world population remained relatively stable until around 300 years ago. Then at the beginning of the 19th century (100 years after population growth started its geometric increase), the demographer Thomas Malthus predicted that population growth would outstrip food pro

6.3.2 Stage 2 Create a mind map

Now you need to think about grouping the ideas, creating a flow for your assignment.

We started by grouping together our ideas and material for the essay on the possible advantages of being a mature student. This helped us to create a mind-map by seeing where links could be made and so made it much easier to decide where the weight of evidence was taking our argument (Author(s): The Open University

5.1 Identifying edges of a polygon

In this section, we revisit the construction of surfaces by identifying edges of polygons, as described in Section 2. Recall that, if we take any polygon in the plane and identify some of its edges in pairs, then we obtain a surface. When specifying how a given pair of edges is to be identified, we choose one of the two possible relative orientati

15.301 Managerial Psychology Laboratory (MIT)
We function in our personal and professional lives based on knowledge and intuitions. Our intuition that we know a lot is very powerful. But sometimes intuitions are accurate and sometimes they are not; without research, it is hard to tell. This course combines a few different goals: develop a critical eye for making inferences from data; be able to carry out simple data analysis; learn about managerial psychology; develop interesting new questions about managerial psychology and test these ques

Graphene - The Strongest Material Known to Man
Graphene is in incredibly strong, one-molecule thick layer of carbon atoms that could someday be used to create life-sustaining nanorobots. The promise is that in the coming decades with carbon nanotubes, with graphene, we’ll create even new substances which can replace the silicon of computers, maybe even give us a space elevator. Graphene for example, is a substance made out of one-molecule-thick layer of carbon. Think about that.  (02:11)
