The present study was designed to obtain evidence as to whether the distorted images drawn by mentally retarded subjects are possibly due to perceptual variables, to the lower level of motor coordination they experience, or to an interaction of both.

Using postulations formulated by Harlow, very few investigators have experimented with discriminative learning in relation to various levels of human mental abilities to the pattern of forming a set. The present study was designed to investigate the effects of different levels of mental abilities on the formation of these sets, using mental retardates, and analyzing the formation of these sets and the abilities of these retardates to shift dimension of cues by reversing the response conditions.

The problem is to determine if there are discrepancies between self-ideal concept which come about through changes in position with respect to group standing, and to what problems specifically that change is related to.

The idea of the Texas Revolution as an internal conspiracy cannot be eliminated. This thesis describes the role of a small minority of the wealthier settlers in Texas in precipitating the Texas Revolution for their own economic reasons. This group, made up of many of the leading figures in Texas, were, for the most part, well-to-do farmers, merchants, and professional men.. Most of them were slaveholders, and their prosperity depended upon the continued existence of this institution. In their minds, the entire economic growth and development of Texas rested upon slavery. When the Mexican government began to threaten the economic future of Texas by the passage of prohibitatory laws on slavery and commerce, many of the leaders in Texas began to think of freeing Texas from Mexican control. The threat to their own economic position and prosperity gave birth to the idea of Texas independence.
