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.     

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.     

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.     

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.     

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.     

General processes, rather than "goals," explain imitation errors

The goal-directed theory of imitation (GOADI) states that copying of action outcomes (e.g., turning a light switch) takes priority over imitation of the means by which those outcomes are achieved (e.g., choice of effector or grip). The object < effector < grip error pattern in the pen-and-cups task provides strong support for GOADI. Experiment 1 replicated this effect using video stimuli. Experiment 2 showed that shifting the color cue from objects to effectors makes imitation of effector selection more accurate than imitation of object and grip selection. Experiment 3 replicated this result when participants were required to describe actions. Experiment 4 indicated that, when participants are imitating and describing actions, enhancing grip discriminability makes grip selection the most accurately executed component of the task. Consistent with theories that hypothesize that imitation relies on task-general mechanisms (e.g., the associative sequence learning model, ideomotor theory), these findings suggest that imitation is no more or less goal directed than other tasks involving action observation.
