The moderating effects of stimulus valence and arousal on memory suppression

This study examined the separate and combined effects of stimulus valence and arousal on retrieval inhibition. Participants performed Anderson and Green's (2001) memory suppression task with stimuli varying across dimensions of valence and arousal. Memory was tested through free and cued recall as well as speeded recognition. Results showed that both stimulus valence and arousal influenced the extent to which participants successfully inhibited retrieval, but not in the ways anticipated. Specifically, the strongest inhibition effects were for highly arousing, pleasant words. In addition, unpleasant stimuli that were suppressed were better recalled during both cued and free-recall tasks than pleasant stimuli that were suppressed. Across all tests of memory performance, there were no significant differences between the experimental conditions for highly arousing, unpleasant words. The implications of these findings are discussed.     

PSYCHOLOGICAL OUTCOMES AMONG LESBIAN SEXUAL ASSAULT SURVIVORS: AN EXAMINATION OF THE ROLES OF INTERNALIZED HOMOPHOBIA AND EXPERIENTIAL AVOIDANCE

This study explored the relations among internalized homophobia (IH), experiential avoidance, and psychological symptom severity in a community sample of 72 lesbian sexual assault survivors. Results indicated that IH is associated with both experiential avoidance and posttraumatic stress disorder (PTSD) symptom severity. In addition, experiential avoidance is related to both PTSD and depression symptom severity. Finally, experiential avoidance completely mediated the relation between IH and PTSD symptom severity. The implications of these findings are discussed and suggestions for future research are provided.     

Project Choices: Adventure-Based Residential Drug Treatment for Court-Referred Youth

Project Choices is a residential treatment program for drug-abusing adjudicated adolescents that employs the adventure-based counseling model to instill change. Its goals have been to reduce conduct-disordered behavior associated with delinquency and drug use. Thus far, the program has proved effective.     

Similarities and differences between MMPI and MMPI-2 applications to the assessment of posttraumatic stress disorder

The purpose of this study was to address the question: Is the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) comparable to the original MMPI in its applicability to the assessment of posttraumatic stress disorder (PTSD) among Vietnam combat veterans? The question was addressed by administering both the original MMPI and MMPI-2 to 29 subjects classified as meeting Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; DSM-III-R) criteria for PTSD and comparing MMPI and MMPI-2 scores in terms of: degree of association, code-type congruence, diagnostic hit rates (when compared to two other clinical samples, and one normal sample), and congruence of the Keane PTSD Scale (PK). Results reveal highly significant correlations between MMPI and MMPI-2 basic scales for the PTSD sample as well as congruence in 2-point codes comparable to previous studies. The MMPI-2 was found to identify effectively PTSD subjects from the other groups. Results also showed a high degree of association between the MMPI and MMPI-2 in regard to PK scores, although minor differences were found in PK raw scores between the two tests. Overall, the findings suggest a high degree of comparability between the MMPI and MMPI-2 in the assessment of PTSD.     

Adrenoleukodystrophy. Clinical-pathologic case history and literature review]

This article presents the clinical and pathological history of a 10-year-old boy with adrenoleukodystrophy as well as a tabular survey of 17 additional cases of which the necropsy records were published in the literature. So far as the case of adrenoleukodystrophy directly observed by the authors themselves is concerned, commencement of the disease was in the seventh year of life, with symptoms of Addison's disease and diffuse inflammatory cerebral sclerosis being observed at about the same time. The cerebral disease manifested itself as a progressive pseudobulbar and pyramidal tract symptomatology and as a progressive cerebral psychosyndrome reminiscent of an endocrinal psychosyndrome. Morphologically, the adrenoleukodystrophy was characterized by severe dystrophy of the cortex of the suprarenal gland and the brain are considered the points of action of a still unknown noxa.e suprarenal gland as well as by extensive sudanophilic processes of decomposition in the cerebromedullary substance, putamen, pallidum, and thalamus. Striated cells and cytoplasmic filamentous inclusions observed in the brain and suprarenal glands in a number of cases reported in the literature were not found by the present authors. The cortex of th     

Distinguishing stereotype threat from priming effects: on the role of the social self and threat-based concerns

It has been argued that priming negative stereotypic traits is sufficient to cause stereotype threat. The present research challenges this assumption by highlighting the role of the social self and targets' concerns about confirming a negative group-based stereotype. Specifically, in 3 experiments the authors demonstrate that stereotype threat adversely affects the test performance and threat-based concerns of targets (but not nontargets) because only targets' social self is linked to the negative group stereotype. Trait priming, however, harms the test performance of both targets and nontargets but has no effect on their threat-based concerns because trait priming does not require such a link between the social self and the group stereotype. Moreover, the authors show that merely increasing the accessibility of the social self in nonthreatening situations leads to the underperformance of targets but has no meaningful effect on nontargets' test performance.     

Tonic immobility and childhood sexual abuse: a preliminary report evaluating the sequela of rape-induced paralysis

The present study examined tonic immobility (TI) in victims of childhood sexual abuse (CSA). Female undergraduates (n=39) and female psychiatric inpatients (n=41) who experienced CSA completed a series of questionnaires assessing aspects of their victimization history, psychological functioning, and TI symptoms. Over fifty-two percent of all participants reported TI in response to CSA. Episodes of CSA involving attempted or completed penile/vaginal penetration were more likely to be associated with an increased likelihood of experiencing TI, and report of TI was associated with greater current psychological impairment. The implications of these findings are discussed, and suggestions for future research are offered.     

A fuzzy trace analysis of categorical inferences and instantial associations as a function of retention interval

Two experiments on children's inferences and associative memory provided a test of predictions from fuzzy-trace theory. Specifically, it was expected that gist-based false recognitions would increase with age and that false recognitions would be uncorrelated with verbatim memory. In Experiment 1, children in Grades 1 through 5 heard lists of category labels, clustered instances from categories, and individual instances. On an immediate test, children indicated whether or not they had previously heard a series of individually presented test words. This list consisted of old words, new words, or words that were categorically or semantically related to the studied word clusters. Children made more false recognition errors for instances than for categories. Verbatim memory and inferences were unrelated. In Experiment 2, the effect of a test delay on categorical inferences and associated instances was examined with children in Grades 1 to 6. With delay, false recognition of associated instances declined for children at all grade levels. In contrast, categorical inferences increased with delay for older children. Verbatim memory and inferences were uncorrelated under immediate and 1-day delay conditions, but there were some low but significant correlations across grades under the 7-day delay. The results of the two experiments are interpreted as supporting fuzzy-trace theory.
