Although plagued by inconsistencies, and methodological problems, research suggests that this level of caffeine ingestion may have significant effects on cardiovascular functioning, and behavioral processes such as attention, cognitive processing, memory, and task performance.

Although children consume significant quantities of caffeine, very little research has been done on the effects of caffeine in children. The limited findings suggest that caffeine consumption may affect the cognitive and behavioral …

Changes In Hypnotizability As A Function Of Suggestion-Based Experimenter Manipulations, Marlin 0. Trulsen

These less responsive individuals could directly benefit from the many medical, …

The Effects Of A Problem-Solving And Imagery-Based Suggestion On Analgesic Responding In Low, Medium, And High Hypnotizable Females, Gloria Haddad Taggett

Dissertations

This study assessed the effects of a problem-solving suggestion as compared with an imagery-based suggestion on analgesic responding in subjects scoring in the low, medium, and high ranges on scales of hypnotizability. Subjects were exposed at separate intervals to either an hypnotic suggestion patter containing specific imagery designed to enhance analgesic performance, or alternatively to a suggestion patter that provided only general problem-solving direction, but contained no specific imaginal guidance. Performance was assessed using two duration measures on a cold-pressor test. Specific measures included both the total time duration a subject held the target hand in cold water (tolerance) as …
