Grades are based on exam performance.  The first two midterms count 25% each, and the final counts 50%.  The second midterm is not cumulative, but the final is.  For each exam, an average of two best scores is computed and every score is normalized to it.  All exams are multiple-choice.  Conventional cutoff points are used. A: 90% and above, B: 80% - 89%, C: 70% - 79%, D: 60% - 69%, F: below 60%.

 

Week 1:

Chapter 1 – Introduction (pages 1 - 22).

       -  Sensation vs. Perception.

       -  The historical and scientific roots of perception. 

       -  Approaches to the study of perception. 

       -  Anatomy and physiology of the neuron.

Chapter 2 – Psychophysics (pages 23 - 42).

       -  Absolute and difference threshold.  Weber’s Law. 

       -  Classical psychophysical methods (adjustment, limits, constant stimuli). 

       -  Psychometric function. Point of subjective equality. 

       -  Signal detection theory and experiment. 

       -  Magnitude estimation (Fechner’s and Stevens’ Laws).

Weeks 2 and 3:

Chapter 3 – The visual system (pages 46 – 88).

       -  Light sources: primary & secondary.

       -  Wave theory of light.

       -  Reflection and refraction.

       -  Prisms and lenses.

       -  Eye ball.  Cornea, lens, retina.  Accommodation.

       -  Retina.  Receptors (rods and cones).  Fovea.  Shadows of blood vessels (demo).

       -  Bipolar, amacrine, horizontal and ganglion cells.

       -  Optic disk – blind spot (demo).

       -  Receptive fields of retinal ganglion cells.

       -  Optic chiasm.  Lateral geniculate nucleus.  Striate cortex.  Receptive fields.

       -  Corpus callosum.  Split brain.

       -  Two visual pathways.  Shape vs. space perception – Ungerleider & Mishkin’s experiment.

Week 4:

Chapter 4 – Fundamental visual functions and phenomena (pp. 89 – 108).

       -  Duplicity theory.  Spectral sensitivity curves.

       -  Dark adaptation.

       -  Limits of basic visual function – Hecht, Shlaer & Pirenne’s experiment.  Spatial and temporal summation.

       -  Visual acuity, visual angle.

       -  Eye movements.

Week 5:

Review and Exam 1.

             Exam 1:  Sep 21.

Week 6:

Chapter 5 – Color vision (pp. 116 – 141).

       -  Dimensions of color.  Chromatic and achromatic colors.

       -  Newton’s contributions: dispersion of sunlight; color mixture; color circle model.

       -  Trichromatic theory:  T. Young – blue, green, red channels.  Yellow, white are complex percepts. 

       -  Opponent process theory – E. Hering: red/green, yellow/blue, bright/dark channels.  Yellow is a simple percept.

       -  Hurvich & Jameson’s (1951) experiment.  Measuring the strength of colors.  Binocular fusion of pure green and pure red leads to the percept of gray, contradicting the trichromatic theory.

       -  Physiological correlates of the opponent theory.

       -  Color constancy.

       -  Defective color vision.

Week 7:

Chapter 6 – Visual pattern and form perception (pp. 142 – 158).

Week 8:

 Chapter 7 – Higher processes of perceptual organization (pp. 168 – 193).

       -  Structural Psychology – mental chemistry (Wundt).

       -  “Wetness” demo.  Percepts are composed of elementary sensations.

       -  Gestalt Psychology – “the whole is different from the sum of the parts” (Wertheimer). 

       -  Simplicity and likelihood principles.  Figure - ground organization.

       -  Gestalt grouping principles: proximity, similarity, common fate, good continuation, closure, symmetry.

       -  The “perceptual whole” determines “the perceptual parts” – examples.

       -  The Law (principle) of Prägnanz.

       -  3D percept of a 3D object from a single 2D image.
