Seeing is believing: the reality of hypnotic hallucinations

Two experiments investigated the reality attributed to hypnotic suggestion through subtle projection of a visual image during simultaneous suggestion for a visual hallucination that resembled the projected image. In Experiment 1, high and low hypnotizable participants were administered either a hypnotic induction or wake instructions, given a suggestion to hallucinate a shape, and then the projected image was subsequently introduced. Although highs in both conditions rated the projected image more vividly than lows, highs in the hypnosis (but not wake) condition made comparable reality ratings when the projected image was absent and present. In Experiment 2, high hypnotizable participants were administered a suggestion to see a shape on a wall. For half the participants the suggested image was projected on the wall and then removed, and for half the projection was initially absent and then introduced. Participants who had the projection absent and then present reported comparable reality and vividness ratings when the projection was absent and present. These findings indicate that elevated hypnotizability and hypnosis are associated with attributions of external reality to suggested experiences.     

WASI profile variability in a sample of psychiatric inpatients

This study examined the variability of Wechsler Abbreviated Scale of Intelligence profiles using the subtest range and profile variability index in a sample of 70 psychiatric inpatients. The subtest range and profile variability index were correlated .93 (p<.001), indicating that either measure may be used to assess profile variance. Comparison of profile variability on this abbreviated scale with other Wechsler intelligence scales in similar populations suggests that variability measures are not comparable across the tests.     

Children's understanding of the relation between addition and subtraction: inversion, identity, and decomposition.

In order to understand addition and subtraction fully, children have to know about the relation between these two operations. We looked at this knowledge in two studies. In one we asked whether 5- and 6-year-old children understand that addition and subtraction cancel each other out and whether this understanding is based on the identity of the addend and subtrahend or on their quantity. We showed that children at this age use the inversion principle even when the addend and subtrahend are the same in quantity but involve different material. In our second study we showed that 6- to 8-year-old children also use the inversion in combination with decomposition to solve a + b - (b + 1) problems. In both studies, factor analyses suggested that the children were using different strategies in the control problems, which require computation, than in the inversion problems, which do not. We conclude that young children understand the relations between addition and subtraction and that this understanding may not be based on their computational skills.     

The Effect of Social Context on Gender Self-Concept

In this study we re-examine the role of genderwithin the self-concept and challenge the assumptionthat our gender self-concept is static and consistentacross contexts. We used the Bem Sex Role Inventory (BSRI) to measure masculinity and femininityacross six contexts. These six contexts were interactingwith same sex friends, interacting with other sexfriends, interacting at home, work, and school, and interacting in a social context where one doesnot know many people. Two hundred twenty-three femalesand 52 males from a large public university in theSoutheast participated in the study. A majority of the participants (76%) were Caucasian with 10%being Hispanic, 4% Asian, and 4% African American.Multivariate analyses of variance provided strongevidence for differences across contexts for both males and females. The results indicated that we aredynamic beings and those characteristics associated withgender are dynamic as well.     

Domestic violence and group treatment for male batterers

This paper examines the violent behavior of male batterers toward their female partners. Three major theoretical perspectives addressing the etiology of the male batterer's abusive behavior are reviewed. These perspectives, along with an understanding of personality characteristics common among batterers, offer insight into intervention and treatment options. Group intervention has proven to be the most effective form of treatment for batterers. Outcome studies suggest a decline in batterers' abusive behavior as a result of group treatment.     

Individualized learning environments: Intra- and interpersonal consequences

This study examines the effects of individual goal structures on the intra- and interpersonal behavior of 120 fourth-grade children. Each group of four children was introduced to one of two individualized learning programs: (a) workbook materials color-coded according to level of difficulty (allowing implicit comparisons among children as to progress), and (b) materials not coded according to difficulty (discouraging comparisons). In both learning programs, children worked individually (at story writing) and were rewarded for the work. Results indicate that boys, but not girls, who were rewarded equally for doing good work in an individualized setting but who start and end at a lower step than other more frequently took away a toy from those peers with whom they compared themselves than did boys who were rewarded equally for good work and where there were no comparisons. Boys as a group, regardles of condition, gave more prize tickets to themselves than to others and gave more prize tickets to themselves than girls gave either to themselves or others. Both boys and girls appear to adopt the evaluations of their work given by the experimenter and appear to be influenced thereby in later prized-giving to themselves and to others.     

Students' ratings of occupational dimensions of traditionally male and traditionally female occupations

The purpose of the present study was to investigate four traditionally male occupations and four traditionally female occupations on a number of dimensions which people use to judge the prestige or importance of a job. Workers were pictured on one form in their traditional roles and on a second form in nontraditional roles. Results indicated a tendency for subjects to give lower ratings to workers in nontraditional jobs. More importantly, for the two “objective” dimensions, money and education, boys and girls agreed on job ratings; however, on the two more “subjective” dimensions, respect and importance to the community, boys gave higher ratings to the male jobs, while girls gave higher ratings to the female jobs.     

Mapping sex group stereotypes of elementary and high school students

This study investigated the sex group stereotypes of youths of elementary and high school age. A total of 60 males and 60 females evaluated boys and girls on a semantic differential type scale. The results indicated that younger members of both sexes were more positive about their own sex and more negative about the opposite sex than were their older counterparts. In addition, adolescent males, but not adolescent females, adopted more favorable evaluations of the opposite sex over their own sex group. Possible explanations are offered to account for these findings.

Excitation and hedonic valence in the effect of erotica on motivated Intermale aggression

The excitatory potential (low, high), the hedonic valence (negative, positive), and the type of content (erotic, non-erotic) of visual stimuli were varied in a factorial design. Male subjects were provoked by a same-sex peer, exposed to communication or, in a no-exposure control, made to wait for a period of time equal to that of communication exposure, and then provided with an opportunity to retaliate against their annoyer. High excitatory potential and negative hedonic valence were found to combine additively in a facilitative effect on retaliatory aggression. No appreciable differences were found in the effect of excitationally and hedonically matched erotica and non-erotica. Exposure to either arousing and displeasing erotica or non-erotica produced levels of aggression significantly above the level associated with the no-exposure control. Exposure to comparatively non-arousing and pleasing erotica or non-erotica failed to reduce aggression, however. The findings were considered to support a model that projects the effect of erotica on retaliatory aggression as a joint function of their excitatory potential and their hedonic valence.
