    PRELIMINARY INVESTIGATION OF EQUINE LEARNING AND MEMORYLAUREL J. DUNNDEPARTMENT OF PSYCHOLOGYMissouri Western State University” (Retrieved from http://clearinghouse.missouriwestern.edu/manuscripts/97.asp , Title/Introduction). This article details a case study of measuring perception and cognition from a group of six horses. Perception was tested within a group, involving variances of sex, breed, age, and training back round. The horses were all treated under the same conditions prior to testing, as to eliminate any discernable advantages regarding routine, handling and diet. The article discusses and provides charts to demonstrate the horses’ learning ability, as a group and individuals. Includes information that directly relates to sensory perception and its influence over training and information retention.

    Photopigment basis for dichromatic color vision in the horse. Carroll J, Murphy CJ, Neitz M, Hoeve JN, Neitz J.Department of Cell Biology, Neurobiology & Anatomy, Medical College of Wisconsin, Milwaukee, WI, USA.“Horses, like other ungulates, are active in the day, at dusk, dawn, and night; and, they have eyes designed to have both high sensitivity for vision in dim light and good visual acuity under higher light levels (Walls, 1942). Typically, daytime activity is associated with the presence of multiple cone classes and color-vision capacity (Jacobs, 1993).  

    Horses can see color in some hues. This is proven by the presents of cones and rods in the horses eyes. Cones which provide color and rods which show shapes. The debate that is on going now is what colors the horse can and can’t see.

    This article is a chapter out of Ultimate Horse Care which covers the topics of the equine nervous system, equine senses and equine learning. The discussion on equine senses starts about midway through the article with sight. It then goes on to explain each of the five senses – sight, hearing, smell, taste and touch – in detail before it continues on into learning and memory.

    The effect of stimulus height on visual discrimination in horses1C. A. Hall*,2, H. J. Cassadayand A. M. Derrington* School of Land-based Studies, Nottingham Trent University, Brackenhurst College Campus, Southwell, Nottinghamshire, England NG25 0QF and School of Psychology, University of Nottingham, University Park, Nottingham, England NG7 2RD This is a case study designed to test the effect that the height of a horse’s head has on their vision and how this affects their training process. There were 8 different horses used in the study  and in the end if was found that all horses responded better to stimuli that was presented at ground level.
