Rape myths are those beliefs which could justify rapes. In the present studies, four kinds of myths focusing on feminine sexuality were measured by using of Burt’s (1980) questionnaire. These were woman’s acceptance of sexual violence, unconscious wish to be raped, carelessness, and frame-up of being raped. In the Study 1, the degree of acceptance for these myths was compared between 70 male and 73 female university students. The result that the males expressed more acceptance for the myths than the females suggests that these are derived from some erroneous concepts concernig femine sexuality. To examine the relationships between the rape myths and rape, in the Study 2, the questionnaire was administered to male prisoners (19 rapists and 56 nonrapists). It was found that the rapists believed more strongly than the non-rapists the myth that women have an unconscious wish to be raped. This was interpreted in the following three ways. (1)The rape myth may have a motivating power for the rapists by evoking their need for dominance over women. (2)The rape myth may have an neutralization effect on raping behavior; as reducing the rapists’ inner inhibitions against rape. (3)The rape myth may lead the rapists to erroneously perceive the victims as that the victims would accept their sexual coercion.

The purpose of this study is to determine types of stimulant-dependence, using prisoners from Osaka Detention House as the subjects.

Hayashi’s Method For Quantification III study of pattern analysis of stimulant dependence, was conducted, followed by a path analysis of the genesis of stimulant dependence patterns.

There were 100 male prisoners, as subjects, who had used stimulants in excess of 500 times over a 5 year period.

Using two dimentions for patterning : the degree of abuse and the depth of dependence, there were four types of stimulant-dependence and causal factors found. They are as follows :

1. Habitual User Type : These subjects used stimulants frequently, for long periods of time, without disrupting their life styles. Because of their deep involvement in crimes, the subjects had difficulties in resisting stimulant abuse.

2. Subculture Type : These subjects used stimulant drugs for purposeful motives, such as sexual pleasure, gambling or staying awake. Normally, the drug use was influenced by organized criminals or fellow peers. Their first criminal act was not committed until a later age, resulting in a less usage of and dependencs on drugs than the other types studied.

3. Escape Type : These subjects come from relatively good families. However, because of their dependence on their parents or their lack of self control, they began using stimulants to escape every day difficulties.

4. Destructive Type : These subjects were found to have a toxic psychosis to drugs : they used large doses of stimulants as their tolerance for the drug increased. Normally, these subjects come from unstable families, leaving home and becoming involved in crime at an early age.
