SINDSCAL source weight transformations are not always necessary or desirable: reply to Hodgkinson

Hodgkinson (1998) argues that we should have transformed the SINDSCAL source weights we used for an analysis presented on page 15 of our paper on the judgement of HIV cases (Irwin, Jones, and Mundo, 1996). In this reply we present theoretical and empirical arguments for why we did not transform the weights. Our statements are presented in the context of a more general discussion of how source weights should be interpreted and used. © 1998 John Wiley & Sons, Ltd.     

An Exploratory Study of HIV+ Adolescents’ Spirituality: Will You Pray with Me?

The aims of the study were (1) to determine whether adolescents find it acceptable to have physicians explore their spiritual beliefs as part of their medical care, (2) to characterize the role of spirituality and religious beliefs in adolescents with and without HIV, and (3) to examine associations between spirituality/religion and quality of life. Adolescents receiving their medical care at an urban Adolescent Health Clinic completed a study-specific questionnaire about spiritual inquiry by their physician, the Brief Multidimensional Measurement of Religiousness/Spirituality, and the Pediatric Quality of Life Inventory 4.0. Chi-squared analysis, Fischer’s exact test, and t tests were used to assess associations. A total of 45 participants enrolled: 19 HIV+ (53% vertical transmission) and 26 HIV?; mean age 17.2 years; 80% African American. Four out of 45 (9%) had ever been asked by their doctor about their spiritual/religious beliefs, and only 8 (18%) had ever shared these beliefs with their healthcare provider. Most teens wanted their provider to ask them about their spiritual beliefs during some visits, especially when dealing with death/dying or chronic illness (67%). Those with HIV were more likely to endorse wanting their doctors to pray with them (42% vs. 15%), feeling “God’s presence” (Mean = 3.95 vs. 2.83), being “part of a larger force” (Mean = 2.58 vs. 1.69), and feeling “God had abandoned them” (Mean = 1.63 vs. 1.15). There are certain circumstances in which healthcare providers should include a spiritual history with teenage patients. Few differences emerged in the teens studied with and without HIV.     

The Miranda Warnings and the Deaf Suspect

Administration of the Miranda Warnings to deaf suspects poses many legal issues. If police officers, judges, attorneys and psychologists are unaware of these, evidence obtained as a consequence of deaf suspects waiving their Miranda Rights may be inadmissible in court. These issues include the importance of videotaping the police interview, the use of sign language interpreters, the determination of the deaf defendant's reading level and communication capacity, the limitations of lipreading, and other psycholinguistic factors. Recommendations are offered to aid in determining whether a deaf suspect is capable of understanding the Miranda Warnings and how these warnings should be administered.     

Context effects in visual length perception: role of ocular,retinal, and spatial location

In three experiments, we examined the transfer of orientation-contingent context effects between the eyes and across portions of the retina with or without variation in external spatial location. Previous research had shown that vertical lines are judged long, relative to horizontal lines, when the stimulus set comprises relatively long horizontals and short verticals (Contextual Condition B), as compared with the reverse when the stimulus set comprises relatively short horizontals and long verticals (Contextual Condition A). Consequently, the contextual set of stimuli influences the magnitude of the horizontal-vertical illusion (HVI), decreasing its size under Contextual Condition A and increasing its size under Contextual Condition B. Experiment 1 showed that exposing one eye to different stimulus contexts modulated the size of the HVI at the exposed eye but had little or no effect at the other eye. Experiments 2 and 3 showed that the effect of the contextual sets generalized poorly across adjacent portions of the retina but transferred almost perfectly across different locations in external space when retinal location was constant. Thus, orientation-contingent context effects in visual length perception appear to be specific to the eye and to the region of the retina stimulated, suggesting that these effects reflect relatively early and local changes in sensitivity, rather than relatively late and general shifts in response criteria.     

Gunther von Hagens' BODY WORLDS: Selling Beautiful Education

In the BODY WORLDS exhibitions currently touring the United States, Gunther von Hagens displays human cadavers preserved through plastination. Whole bodies are playfully posed and exposed to educate the public. However, the educational aims are ambiguous, and some aspects of the exhibit violate human dignity. In particular, the signature cards attached to the whole-body plastinates that bear the title, the signature of Gunther von Hagens, and the date of creation mark the plastinates as artwork and von Hagens as the artist in a gesture that strips the personal dignity from the donors. I conclude that the educational use of cadavers is compatible with respect for dignity if: 1) the utility of such use is great enough; 2) there are no other ways of achieving these ends; and 3) every effort is made to honor the dignity of the donors.     

Psychometric and Piagetian intelligences: Toward resolution of controversy

Whether “psychometric” and “Piagetian” kinds of intelligence, as measured by instruments designed to measure these constructs, are the same or different is regarded as a question of whether they have the same or different courses of development with age. While factor analysis may not be fully adequate for investigation of this question, use of this technique with variables reflecting chronological age variation must involve elimination of the age effect in order to assess relations among the constructs measured. Humphreys and Parsons (1979) were justified in partialing out age in their reanalysis of a study by Stephens, McLaughlin, Miller, and Glass (1972), to show that the two constructs are highly correlated and possibly identical in the sample studied. Reanalyses of studies by DeVries and Kohlberg (1977) and by DeVries (1974) yield somewhat conflicting results on the identity between psychometric and Piagetian intelligences. The former study does not yield a convincing separation between them, whereas the latter suggests that they can be distinguished, though substantially correlated and both loaded with a general factor. Problems in further investigating the issue are discussed.
