Cultural Variables

As part of a battery, the Benton Revised Visual Retention Test was individually administered to 100 black adolescent students in southeastern Virginia, aged 12 or 13 yr. The Benton test, Form C, Administrations A and C were scored for both Total Errors and Total Number Correct. A multivariate analysis of variance indicated no significant differences between ages, but there were differences between boys' and girls' scores. There were two significant interactions for age, sex, and measured ethnic identity on Administration C for Total Number Correct and Total Errors for the group. Administration A, scored for categorical errors, produced significant univariate F ratios for Total Errors, Distortion, and Total Right Errors on the classification of ethnic identity. Alternative interpretations are feasible, and further research into the influences of experimental and cultural variables on visual perception is needed.

Item Functioning

Although research has extensively documented sources for differential item functioning and stereotype threat—especially among women and black college students—little is known about group differences in test-taking strategies among black adolescent students. In this article, Arbuthnot presents findings from two studies that seek to explore how stereotype threat affects standardized test performance in mathematics among black eighth-grade students. The author contextualizes the studies in a discussion of prior research and presents findings from an analysis of black students'test performances on standardized mathematics exam questions that do and do not include differential item functioning. Arbuthnot complements this work by exploring the strategies test-takers use to process test items. Findings from the two studies suggest that stereotype threat may have a negative impact on black adolescent students'test-taking strategies and achievement on mathematics standardized tests. The author concludes the article by posing implications for new test development that takes into consideration the potential impact of stereotype threat.

ABSTRACT A phytosociological approach to dry forest and cactus communities on the occidental slopes of the Peruvian Andes is presented in base of 164 plots carried out following the Braun-Blanquet method. From them, 52 have been made recently, and the other 112 were taken from the literature. After a multivariate analysis, using a hierarchical clustering and a detendred correspondence analysis, the Acacio-Prosopidetea class (dry forest and cactus communities, developed on soils with some edaphic humidity or precipitations derived from El Niño Current), the Opuntietea sphaericae class (cactus communities of central and southern Peru, on few stabilized rocky or sandy soils) and the Carico-Caesalpinietea class (dry forests of the Peruvian coastal desert, influenced by the maritime humidity of the cold Humboldt Current), are differentiated. Within the Acacio-Prosopidetea class, two alliances are commented: the Bursero-Prosopidion pallidae (with two new associations Loxopterygio huasanginis-Neoraimondietum arequipensis and Crotono ruiziani-Acacietum macracanthae), and the new alliance Baccharido-Jacarandion acutifoliae (with the new associations Armatocereo balsasensis-Cercidietum praecocis and Diplopterydo leiocarpae-Acacietum macracanthae). For the Opuntietea sphaericae class, the association Haageocereo versicoloris-Armatocereetum proceri (Espostoo-Neoraimondion) is described on the basis of plots from hyperarid localities of central Peru. Finally, a typological classification of the studied plant communities is given.

Validity Tests

AbstractObjective:Performance and symptom validity tests (PVTs and SVTs) measure the credibility of the assessment results. Cognitive impairment and apathy potentially interfere with validity test performance and may thus lead to an incorrect (i.e., false-positive) classification of the patient’s scores as non-credible. The study aimed at examining the false-positive rate of three validity tests in patients with cognitive impairment and apathy.Methods:A cross-sectional, comparative study was performed in 56 patients with dementia, 41 patients with mild cognitive impairment, and 41 patients with Parkinson’s disease. Two PVTs – the Test of Memory Malingering (TOMM) and the Dot Counting Test (DCT) – and one SVT – the Structured Inventory of Malingered Symptomatology (SIMS) – were administered. Apathy was measured with the Apathy Evaluation Scale, and severity of cognitive impairment with the Mini Mental State Examination.Results:The failure rate was 13.7% for the TOMM, 23.8% for the DCT, and 12.5% for the SIMS. Of the patients with data on all three tests (n = 105), 13.5% failed one test, 2.9% failed two tests, and none failed all three. Failing the PVTs was associated with cognitive impairment, but not with apathy. Failing the SVT was related to apathy, but not to cognitive impairment.Conclusions:In patients with cognitive impairment or apathy, failing one validity test is not uncommon. Validity tests are differentially sensitive to cognitive impairment and apathy. However, the rule that at least two validity tests should be failed to identify non-credibility seemed to ensure a high percentage of correct classification of credibility.
