The Effects Of Two Types Of Hypnotic Suggestions On Analgesic Responding In Moderately Hypnotizable Subjects, Gloria M. Haddad

Masters Theses

This study assessed the effects of two hypnotic suggestions on hypnotic performance in medium hypnotizable subjects. Subjects were exposed at separate intervals to either an hypnotic suggestion patter containing specific imagery or alternatively to a suggestion patter that provided only general problem-solving direction.

The problem-solving suggestions were shown to increase both threshhold and tolerance of noxious stimulation. The imagery suggestions proved to be effective only for the threshhold measure.

These findings are discussed in terms of their implications for the use of hypnosis with subjects who do …

Reinforcement Effects On The I.Q. Scores Of Institutionalized Children And Adults With Developmental Disabilities, Jody Robin Lewis

Masters Theses

Eighteen institutionalized school-age and adult subjects with severe/profound developmental disabilities were evaluated for the effects of self-selected reinforcement for correct responding on their I.Q. scores when tested with the Stanford-Binet Intelligence Scale (Terman & Merrill, 1960) or the Leiter International Performance Scale (Arthur, 1952). Subjects were tested under both standard and reinforcement conditions. The results indicated that overall, subjects when tested under reinforcement conditions showed a significant increase in mean I.Q. scores when compared with the same subjects tested one month previously under standard conditions. Several features of the data reveal intriguing results with regard to subjects and related preexisting …

The Validity Of Studies That Test The Effectiveness Of Psychotherapy, Ian K. Isaacs

Masters Theses

This thesis is a review of the validity of studies on the effectiveness of psychotherapy. Ten randomly selected studies are examined to determine if the validity of the study was affected by threats to statistical conclusion, internal, construct, and external validity.

The results indicate that validity of the research on the effectiveness of psychotherapy is affected by some threats to validity: History, Testing, and Selection bias, (ie. internal validity). In addition, external validity was affected by the lack of use of appropriate control group, lack of a description of the therapy …
