Timidity, Emotionality, And Activity In Rats Deprived Of Grooming, Josiah B. Henneberger

Master's Theses

The purpose of this current study was to investigate the effect of restriction of grooming, by means of collars, on activity, emotionality, and timidity. On the basis of the common occurrence of grooming when under stress some relationship between licking and emotionality was assumed to exist by the author. it was therefore expected that differences would be found among the treatment group.

The current study made use of a three factor design. One factor was the treatment factor, another factor was the replications factor, and the third was the days factor. The days factor has repeated measures and the replications …

The Relation Between Measured Intelligence And The Ability To Learn, Robert Stephen Peddicord

Master's Theses

There are perhaps as many definitions of intelligence as there are definers. However, one definition which has extensive commonsense appeal, according to Simrall (1947), identifies intelligence with the ability to learn, or to profit from experience. Certainly, many practicing psychologists have interpreted intelligence test scores as reflective of an individual's learning ability or potential for future learning. In his address as retiring president of the American Psychological Association, Garrett commented that: "It is undoubtedly true that intelligence involves the ability to learn..." (Garrett, 1946, p. 372).

Effect Of Maze Arm Alternation On Maze Traversal Latency : Analysis Of The Aftereffects Hypothesis, Ronald Seymour Johnson

Master's Theses

Clark Hull (1952) proposed that nonreinforccd trials facilitate distinctive after effects and used this "aftereffect" theory to account for the PREE (the greater resistance to extinction of partially rewarded Ss as compared to continuously rewarded Ss). The theory proposed that stimulus traces of a nonrewarded trial (S^N) persist and are conditioned to the locomotor response (R_i) on trials which are reinforced and preceded by nonreinforced trials. If t he S^N_>R_i association has been established under partial reward conditions, and since S^N occurs during extinction, PREE is predicted.

Effects Of Category-Relevance, Retention Measure, And Category-Affiliation Upon Retention Of The Aging, Gary M. Tyson

Master's Theses

The present investigation represents an attempt to further explore several parameters of short-term memory as a function of the relevance of appropriateness of the verbal materials utilized. It is the author's contention that due to changing patterns of interests and experiences accompanying chronological aging, certain types of verbal material vary with respect to their relevance for use with aging populations. In regard to parameters of short-term memory, the present study contains provisions for exploring efficiency of retention as a function of the retention measure; and category•affiliated as opposed to randomly-selected words. A more complete and integrated formulation is presented in …
