Differences in Ability of Facial and Object Image Recognition and Its Suggestibility by Image Rotation
Differences in ability of facial and object image recognition and its suggestibility by image rotation
Abstract
The ability of face and object image recognition and it s suggestibility by image rotation was examined on first year Psychology students of University of
London
(N=59).
“Subject”
participants from assigned pairs were presented with a series of images including faces and objects where 50% of the images were inverted. “Subject” participants had to recognise these objects and faces as quickly as possible. This performance was measured and recorded by the
“experimenter”
participant from the pair. H1 – Participants will perform poorer
(less accurate and slower) at recognising images of inverted faces in comparison to images of upright faces. H2 – Inversion of the images will have greater effect on recognition of faces rather than on objects. Wilcoxon Signed Rank tests revealed significant difference for both H1 and H2 one-tailed hypotheses (p<
.0001). Descriptive statistics and bar charts revealed the direction of these differences. These findings are congruent with previous studies although causations of these phenomena are difficult to suggest due to poor understanding of these processes. Direction of further research was suggested to focus on these processes.
Introduction
The recognition of faces and the processes behind this phenomenon has greatly intrigued psychologists over the past several decades. If we consider the fact that there are over 6.6 billion people on the planet and no two faces are exactly the same, it suggests how subtle differences differentiate one from another. It seems that the human brain has developed sensitivity particularly to facial features. But do we recognise faces as a whole or as a set of individual features? And more importantly, does remembering, recognising and processing of faces differ from the processing and remembering of objects?
