Using HLM to Explore the Effects of Perceptions of Learning Environments and Assessments on Students’ Test Performance

The study examines the role that perceptions or impressions of learning environments and assessments play in students’ performance on a large-scale standardized test. Hierarchical linear modeling (HLM) was used to test aspects of the Learning Errors and Formative Feedback model to determine how much variation in students’ performance was explained by students’ and school principals’ perceptions of learning environments and assessments. Results from sequential HLM testing indicated that students’ but not principals’ perceptions explained a significant, although modest, amount of the total variation in students’ test performance. These results suggest that when students perceive learning environments to be safe and valuable, and positive assessment activities to be taking place, they tend to perform better on standardized tests than when they perceive learning environments and assessment activities otherwise. These findings provide a rationale for investigating the variables that can help improve students’ perceptions in order to enhance their test performance.     

I See Dead People: Insights From the Humanities Into the Nature of Plastinated Cadavers

Accounts from the humanities which focus on describing the nature of whole body plastinates are examined. We argue that this literature shows that plastinates do not clearly occupy standard cultural binary categories of interior or exterior, real or fake, dead or alive, bodies or persons, self or other and argue that Noël Carroll’s structural framework for horrific monsters unites the various accounts of the contradictory or ambiguous nature of plastinates while also showing how plastinates differ from horrific fictional monsters. In doing so, it offers an account of the varied reactions of those responding to exhibitions of plastinated whole bodies.     

Personality and student self-handicapping: A cross-validated regression approach

Researchers have suggested that self-handicapping is a function of personality. According to the Five Factor Model, personality can be understood in terms of openness, conscientiousness, extraversion, agreeableness, and neuroticism. Ross et al. (2002) found lower conscientiousness predicted higher self-handicapping. However, their study was limited by the use of concurrent data. As a result, the purpose of this study was to (1) replicate the findings of Ross et al. (2002) in predicting self-handicapping from conscientiousness and neuroticism, and (2) extend on those findings by cross-validating the prediction equation in a longitudinal sample. The results essentially replicated the findings of Ross et al. (2002), and demonstrated the relationship between personality and self-handicapping tendencies was stable over a one-semester timeframe.     

Use of cue configuration geometry for spatial orientation in human infants (Homo sapiens)

Research with both rats and human infants has found that after inertial disorientation, the geometry of an enclosed environment is used in preference over distinctive featural information during goal localization. Infants (Homo sapiens, 18-24 months) were presented with a toy search task involving inertial disorientation in 1 of 2 conditions. In the identical condition, 4 identical hiding boxes in a rectangular formation were set within a circular enclosure. In the distinctive condition, 4 distinctive hiding boxes were used. Infants searched the goal box and its rotational equivalent significantly more than would be expected by chance in the identical condition, showing that they were sensitive to the geometric configuration of the array of boxes. Unlike the results of studies using a rectangular enclosure, however, in the distinctive condition, infants searched at the correct location significantly more than at other locations.     

Attitudes toward male roles among adolescent males: A discriminant validity analysis

This study investigates the discriminant validity of a measure of attitudes toward male roles, i.e., beliefs about the importance of men adhering to cultural defined standards for masculinity. Using data from the 1988 National Survey of Adolescent Males, the Male Role Attitude Scale (MRAS) is evaluated in terms of (1) its independence from measures of attitudes toward female roles, and of attitudes toward gender roles and relationships, and (2) its differential correlates with and incremental ability to explain variance in criterion variables compared to measures of these two other gender-related attitudes. As predicted, the MRAS is unrelated to attitudes toward the female role, but is significantly associated with attitudes toward gender roles and relationships. As further predicted, the MRAS, but not attitudes toward women or attitudes toward gender roles and relationships, is associated with homophobic attitudes toward male homosexuality and with traditional male procreative attitudes. In addition, the MRAS explains significant incremental variance in these criterion measures when attitude toward female roles and attitude toward gender roles and relationships are controlled for. These results support the theoretical argument that attitudes toward male roles are conceptually distinct from the other gender-related attitudes examined here.This research was supported by grants from the National Institute of Child Health and Human Development and from the Office of Adolescent Pregnancy Programs.

Theodor Meynert′s Contribution to Classical 19th Century Aphasia Studies

Carl Wernicke (1848-1905) is traditionally considered the first to have described the features of, and the brain pathology underlying, impaired auditory comprehension and related symptoms. Although Wernicke (1874) clearly and repeatedly indicates his indebtedness to Theodor von Meynert (1833-1892). this is usually understood as an acknowledgment that Meynert taught Wernicke neuroanatomy (Eggert, 1977); Wernicke′s own words in part support this interpretation. A more sophisticated historical analysis notes that, prior to Wernicke, both Johann Schmidt in 1871 and Charlton Bastian in 1869 had described the concept of receptive aphasia, but neither had supported their analyses with autopsy evidence as did Wernicke, thus not dislodging Wernicke′s claim of priority. However, a virtually unknown work by Theodor von Meynert, published in 1866, has recently been rediscovered by us ["Ein Fall von Sprachstörung, anatomisch begründet." Medizinische Jahrbücher. XII Band der Zeitschrift der K. K. Gesellleschaft der Ärzte in Wien, 22.Jahr. Pp. 152-189]. In this paper Meynert analyzes the anatomical basis for localizing the comprehension of language in the superior temporal gyros, he argues that lesions in this area should (by analogy to Broca′s earlier observations on language expression) cause impairments in language comprehension, and he presents a case of receptive aphasia with autopsy evidence of destruction of the superior temporal gyros in the left hemisphere. The patient′s aphasia was classic: impaired auditory comprehension, and fluent speech with paraphasias. It is clear that Meynert should be given historical credit for his work.     

Combining information from sources that vary in credibility

Models describing the role of source credibility in information integration were tested in two experiments. In the first experiment, subjects estimated the value of used cars based on two cues: blue book value and an estimate provided by one of three friends who examined the car. The three sources were described as differing in mechanical expertise. In the second experiment, subjects rated the likeableness of persons described by either one or two adjectives, each adjective contributed by a different source. The sources differed with respect to the length of their acquaintance with the person to be rated. In both experiments, credibility of the source magnified the impact of the information he provided. Further, this multiplicative effect of a source was inversely related to the credibility of the other source, in violation of additive or constant-weight averaging models, but consistent with a relative-weight averaging model.     

Language localization and variability

Language localization data from 11 neurosurgical patients undergoing cortical resection for medically intractable focal epilepsy were obtained by mapping with bipolar electrical stimulation at current levels below sensory and after-discharge thresholds, during an object-naming task. The topographical extent of language cortex in an individual subject can be wider than that proposed in the classic maps. Within this zone, language is discretely localized, with different sites variably committed to language as measured by the naming function. The naming data from the left cortex of eight patients, all left-brain-dominant, were pooled to determine the variability within the primary language zone. Only a narrow band of posterior, inferior frontal lobe, immediately anterior to motor strip, showed involvement in all of the patients in whom it was sampled. This is a motor speech area; it constitutes only a small portion of the frontal language area. Other infero-frontal, parietal, and postero-temporal sites showed considerable variability, with naming involvement in only 50–80% of the patients sampled. There is a suggestion that some of these patterns of language localization may correlate with poorer verbal abilities. Data were also obtained on language localization in the left insula in a patient who was left-hemisphere-dominant for language. Mapping of the right hemisphere in a left-brain-dominant patient demonstrated no naming function. Mapping of the right hemisphere in one and the left hemisphere in another patient, both of whom were right-hemisphere-dominant for language, suggests more diffuse language representation with right hemisphere dominance.     

When can feedback-seeking behavior result in a better performance rating? Investigating the moderating role of political skill

Feedback-seeking behavior is generally used to acquire job-related information that enables performance improvement. However, it can also be a form of impression management that improves an employee’s reputation. In this study, we show that employees who hold an image enhancement motive are more likely to seek feedback from their supervisors. Further, this feedback-seeking behavior mediates the relationship between the image enhancement motive and task performance ratings, consistent with the self-concept enhancing tactician (SCENT) model. However, we additionally incorporate socioanalytic theory to demonstrate that this indirect effect is moderated: the image enhancement motive translates into greater feedback-seeking behavior and task performance ratings only for employees with high political skill, who are capable of acting on their image enhancement motive successfully.     

Bilingualism,executive control,and age at diagnosis among people with early‐stage Alzheimer's disease in Wales

The observation of a bilingual advantage in executive control tasks involving inhibition and management of response conflict suggests that being bilingual might contribute to increased cognitive reserve. In support of this, recent evidence indicates that bilinguals develop Alzheimer's disease (AD) later than monolinguals, and may retain an advantage in performance on executive control tasks. We compared age at the time of receiving an AD diagnosis in bilingual Welsh/English speakers (n = 37) and monolingual English speakers (n = 49), and assessed the performance of bilinguals (n = 24) and monolinguals (n = 49) on a range of executive control tasks. There was a non‐significant difference in age at the time of diagnosis, with bilinguals being on average 3 years older than monolinguals, but bilinguals were also significantly more cognitively impaired at the time of diagnosis. There were no significant differences between monolinguals and bilinguals in performance on executive function tests, but bilinguals appeared to show relative strengths in the domain of inhibition and response conflict. Bilingual Welsh/English speakers with AD do not show a clear advantage in executive function over monolingual English speakers, but may retain some benefits in inhibition and management of response conflict. There may be a delay in onset of AD in Welsh/English bilinguals, but if so, it is smaller than that found in some other clinical populations. In this Welsh sample, bilinguals with AD came to the attention of services later than monolinguals, and reasons for this pattern could be explored further.
