Perception Flashcards
What is sensation?
the information that we receive through our senses
What is perception?
how we interpret the sensory information that we recieve
What is a monucular depth cue?
a way of detecting depth or distance which requires just one eye
Examples of monocular depth cues
Height in plane - objects that are higher up appear further away.
Relative size - smaller objects in the visual field appear further away
Occlusion - objects that are in front of others appear closer to us while objects behind other objects seem further away
linear perspective - when parallel lines converge in the distance, the point at which they come together is percieved to he further away.
What is a binocular depth cue?
a way of detecting depth or distance that requires two eyes.
Examples of binocular depth cues
Retinal disparity - each eye sees things differently because they are positioned 6cm apart. Retinal disparity is the difference between the left and right eyes view
convergence - the eyes become closer together when objects are close to us. Muscles in the eye work harder objects are close.
Types of data
Quantitative data - numbers - answers that can be counted - easy to analyse, grouos of people can be easily compared. Lacks depth and detail, doesnt reflect how complex things are irl
Qualitative - words or pictures - more depth and detail, researcher can gain more insight.
Primary data - data obtained first hand by the researcher - suits the aims of the research. Authentic. Data may be more useful.
Secondary data - data from sources like otger studies or government statistics. Has been collected by someone else for a different set of research aims. - Convenient to use. Redices expense because it has already been checked and collected. May not fit what the researcher wants. May redice validity.
