Literature in semiotics lacks consideration of the elements in symbols that communicate specific concepts. Prohibition was the concept chosen for study. Potential prohibitors were represented by line configurations superimposed on background symbols. Seven prohibitors coupled with symbol backgrounds to form 49 experimental symbols were studied through a symbol inventory. Prohibitors constituted the independent variable, while dependent variables were verbal responses by 105 college students to the experimental symbols. Two hypotheses were tested: a) Prohibitors differ in effectiveness in communicating prohibition and b) Prohibitors differ in frequency of distortion of symbol meaning. Chi square analyses and comparisons of proportions showed diagonal lines most frequently elicited prohibition responses. A chi square analysis displayed no significant relationship between prohibitors in distortion of symbol meaning.

The purpose was to verify ego states as objectively identifiable phenomena and the influence of early parent-child relationships on their identification using an audio tape of recorded examples of ego states, Thompson's Ego State Tape (EST), and the Roe-Siegleman Parent-Child Relations Questionaire (PCR). No relationship was found between SAT scores and scores on the EST, nor between PCR and EST scores. It was concluded that possibly (1) no relationship existed between how children perceive their parents and the identification of ego states, and (2) that the PCR might not be sampling child rearing practices relevant to the identification of ego states.

This study investigated the use of electromyographic feedback in regulating the frequency of part-word repetitions. Two adult stutterers, one female (Subject A) and one male (Subject B) were employed. The frequency of part-word repetitions during baserate, EMG uV raising, and EMG uV lowering conditions was assessed for Subject B. As hypothesized, results indicate that there was a notable decline in the frequency of part-word repetitions during the EMG uV lowering sessions. However, contrary to the second hypothesis, (i.e. that an increase in EMG uV would correspond with an increase in part-word repetitions) there was also a decline in the frequency of part-word repetitions during the EMG raising sessions.

The present study examined whether a relationship exists between level of rigidity and prejudicial attitudes and whether prejudiced attitudes could be modified as a function of exposure to a competent black model. It was predicted that individuals with a high level of rigidity would display more racial prejudice than low-rigid individuals and that individuals with a low level of rigidity would demonstrate less prejudice than high-rigid individuals after exposure to a competent model. After exposure to a competent model, a significant main effect for rigidity was found which indicated that low-rigid individuals became less prejudiced than high-rigid individuals,
