Psych 101 – Introduction to Psychology – Lecture 4

As we continue to explore the biological basis of human behaviour, the focus shifts to the topic of sensation. In this lecture we examine the roles of stimuli and receptors, define key terms such as absolute threshold, sensory adaptation and just noticeable difference (JND), look at detailed structures of our major sense organs and discuss the different ways in which we experience the world through our senses.
