An account is given of the nineteenth-century case of the Tichborne Claimant, in which someone purporting to be Sir Roger Tichborne, a missing heir, arrived in England from Australia 13 years after Sir Roger had been assumed drowned at sea. Many people, including Lady Tichborne, Sir Roger's mother, positively identified him. Others insisted that he was an impostor. A civil court and a criminal trial each found against The Claimant for various reasons, but the question of The Claimant's true identity remains open to this day. The case of the Tichborne Claimant is used to illustrate issues in identification that are of contemporary interest. The particular matter of how faces change over time is briefly discussed.  相似文献

The purpose of this paper is to explore the relative empirical support for two alternative ways of interpreting the relationship between masculinity and irrationality. The common denominator in this particular relationship was theoretically assumed to either reflect a person's locus of control expectations or his/her level of self-esteem.Two separate empirical studies were performed with groups of undergraduate university students. Both studies replicated earlier results, thus supporting the masculinity hypothesis as the one accounting for the relationship between sex-role orientation and irrationality.Of the two possible common denominators explaining this relationship, level of self-esteem was the one receiving the strongest empirical support. Some interesting gender differences concerning these two possible common denominators were also found.Ole Johan Hovland, Cand.paed., is Assistant professor of Personality Assessment at the Department of Personality Psychology, University of Bergen, Bergen, Norway, and maintains a small private practice in Laksevåg, Bergen, Norway.

Age differences in short-term retroactive interference, unconfounded with age differences in rehearsal in the retention interval of the Brown-Peterson Task, were not found in a cross-sectional study of adults 18-32 and 64-78 years of age. Degree of retroactive interference was manipulated conjointly with distractor interval length (0-15 s). Individual memory span was assessed and used as the list length in order to achieve stimulus equivalence of memory loads across individuals and age groups. An attention-demanding matching task that adjusted itself in difficulty to the individual's attentional capacity was used as the distractor activity. Covert rehearsal during the retention interval was inferred using several measures, including a comparison of distractor task performance in the presence and in the absence of a memory load, and rehearsers were excluded from the primary analyses. We conclude that there is no interference proneness with increasing age in the present study.  相似文献

We set up a mutual help network among the elderly residents of a government-subsidized apartment building and evaluated its impact on their social ties, social support satisfaction, and depression. A quasi-experimental design was used, with the residents of a similar building located in the same neighborhood serving as the control group. A total of 230 individual services were exchanged, and 28 group activities were organized during the study period. There was almost no difference between experimental and control groups with respect to the change over the study period in the number of social ties with other residents of the building. Support satisfaction decreased in both groups, but the decrease was larger in the experimental group. The control group had a slight decrease in the frequency of their depressive symptoms, whereas the experimental group had a moderate increase. More research is needed on the ability of social support interventions to produce beneficial effects on mental health among individuals who are not experiencing a particular life stress.  相似文献

Surviving members of the Berkeley Older Generation Study were interviewed and tested with the Wechsler Adult Intelligence Scale in 1969-1970 and again in 1983-1984, when subjects' ages ranged from 73 to 93. Health was assessed by self-reports at both measurement periods. Although many individuals showed some decline in intellectual functioning, substantial individual differences were apparent at all age levels. More than one half of the subjects showed no reliable change, and a minority showed a reliable increase in verbal scores. The role of self-reported health has increasing importance in the maintenance of intellectual functioning in advanced old age.  相似文献

Several factor analyses of the Millon Clinical Multiaxial Inventory (MCMI) have resulted in very similar solutions. Interpretation of this consistency is hampered by the fact that the 20 scales of the inventory share items. Overlapping items cause the scales to be linearly dependent and may create structure in the interscale correlation matrix which is separate from the subject response patterns. A factor analysis was performed on the matrix of item-overlap coefficients which describes the underlying artifactual structure of the instrument. Data from two new subject samples were factor analyzed and compared to previously published studies. Similarity coefficients among factors across studies were calculated.  相似文献

This article is concerned with psychiatric recommendations for treatment at the Metropolitan Toronto Forensic Service (METFORS), a clinical assessment agency providing both 1-day and 30-day evaluations of criminal defendants in Toronto, Canada. Analysis of both psychiatric reports and quantitative research instruments demonstrated the saliency of treatment as a central forensic issue at METFORS. Among a sample of 592 defendants, 134 were considered in need of outpatient care. Persons recommended for hospitalization were most likely to exhibit histories of mental health rather than criminal justice contacts; to be arrested for nonviolent offenses; to manifest psychotic behavior while at METFORS; to be found unfit for bail, incompetent to stand trial, in need of further assessment and dangerous to self; and to experience higher rates of hospitalization, but lower levels of criminalization during the two years following their initial forensic assessment. Psychiatric reports at METFORS tended to merge recommendations for treatment and assessment; to suggest prison or probation as means for securing clinical treatment; and to provide little written support for judgments about the need for intervention. Along with competency and dangerousness, treatment is a key issue in forensic practice, and warrants further attention in the psycholegal literature.  相似文献

Clinical judgments on the treatability and prognosis of mentally disordered offeenders (MDO) may strongly influence legal dispositions and the availability of treatment resources. This study examined 1,238 discharge summaries for MDOs referred for court assessments. Psychiatrists evidenced marked variability in how often they recommended treatment and how frequently they judged patients to have a poor prognosis. Two logit analyses suggested that diagnosis and consultation by other clinicians were associated with (a) treatment recommendations (i.e., Axis I diagnosis and social work consultations) and (b) prognosis (i.e., Axis II diagnosis and psychology consultations).  相似文献

Young and older adults were presented with pictures for study. Their recognition of the information was tested at five retention intervals: immediately, and 48 hr, 1 week, 2 weeks, and 4 weeks later. The main finding of interest was that picture recognition did not show an age-related decline until the 1-week retention interval.  相似文献

Aging has previously been shown to produce a generalized proportional slowing of all cognitive operations. In contrast, the present results suggested that Alzheimer's disease produces a disproportionate reduction in the speed with which patients carry out one or more mental operations. The tasks that demented patients found particularly difficult involved either a self-directed search of their lexicon or the use of familiarity information.  相似文献
