Effects of antecedent variables on disruptive behavior and accurate responding in young children in outpatient settings

The effects of manipulations of task variables on inaccurate responding and disruption were investigated with 3 children who engaged in noncompliance. With 2 children in an outpatient clinic, task directives were first manipulated to identify directives that guided accurate responding; then, additional dimensions of the task were manipulated to evaluate their influence on disruptive behavior. With a 3rd child, similar procedures were employed at school. Results showed one-step directives set the occasion for accurate responding and that other dimensions of the task (e.g., preference) functioned as motivating operations for negative reinforcement.     

A study of the antecedents and consequences of psychological ownership in organizational settings

Psychological ownership is a feeling of possession in the absence of any formal or legal claims of ownership. In this study, the authors aimed to extend previous empirical testing of psychological ownership in work settings to encompass both job-based and organization-based psychological ownership as well as related work attitudes and behavioral outcomes. Questionnaire data from 68 employees and their managers revealed that job-based psychological ownership and organization-based psychological ownership are distinct work attitudes that are distinguishable from job satisfaction and organizational commitment. Psychological ownership predicted job satisfaction and organizational commitment and mediated the relationship between autonomy and these work attitudes. There was no support for a relationship between psychological ownership and behavioral outcomes. The authors discuss the limitations of the study and the implications of psychological ownership.     

How Do Children Stigmatize People With Mental Illness?

A way to promote eliminating stigma surrounding mental illnesses is targeting the phenomenon in children. This study's purpose is to validate models of mental illness stigma on children in Grades 6–8. Children completed the revised Attribution Questionnaire in a pretest of a larger study on a mental health education program. Data from this study permitted testing of roles of demographics in these social cognitive models. Subsequent analyses using manifest model structural equations were mixed, but mostly showed adequate fit for multiple versions of the models. These results suggest that models of blame and dangerousness are relevant to the way 10 to 13-year-olds stigmatize mental illness. Demographics were not found to fit these models satisfactorily. Implications of these findings for stigma-change agenda are discussed.     

Hyperperfusion syndromes: insight into the pathophysiology and treatment of hypertensive encephalopathy

Hypertensive encephalopathy is one of the manifestations of a hypertensive crisis. It is not the absolute value of the blood pressure that causes the encephalopathy, rather the presence of an abrupt rise in pressure. In terms of clinical and radiographic findings, there are many similarities among a group of entities, including hypertensive encephalopathy, eclampsia, and immunosuppressant neurotoxicity. Hyperperfusion syndromes may represent these clinical disease states that may share the same pathophysiology. Magnetic resonance imaging fluid attenuated inversion recovery sequences have recognized the prominent cortical involvement of the disease that had been previously missed on computed tomography. Studies have found cortical involvement in 94% of their patients, particularly in mild cases. Animal models demonstrate endothelial damage and enhanced pinocytosis in the cortex as reasons why edema may begin in that region of the brain. Patients diagnosed with hypertensive encephalopathy should be diagnosed and treated promptly in order to avoid further neurological complications. The mean arterial pressure should be lowered by 20% to 25% within the first hour of patient presentation, followed by further gradual reduction in blood pressure over the following 24 hours. Hypertensive emergency in acute ischemic stroke should be managed with more caution. According to the 2003 American Stroke Association treatment guidelines, for patients with ischemic stroke not eligible for thrombolytic therapy, target blood pressures are a diastolic blood pressure <120 mmHg and systolic blood pressure <220 mmHg. The systolic pressure must be <185 mmHg and diastolic pressure <110 mmHg at all times if eligible for thrombolytic therapy.     

Progressive age-related changes in the attentional blink paradigm

Previous studies on aging and attention typically examine group differences between younger and older adults, rather than seeing aging as a continuous process. Using correlational analyses, this study examined progressive changes in the magnitude of the attentional blink (AB) associated with aging. Increased age was found to be significantly associated with the ability to detect the second target (T2), whereby older age was correlated with the production of a longer and more pronounced AB; this supports the proposition that aging is associated with reduced inhibitory processes and selective attention. It was also found that AB performance somewhat improves between ages 18-39 years, but tends to decline from 40 years of age onward, providing an interesting and novel finding that AB effects may become more sensitive at this point in time. The AB task may prove useful in the assessment of selective attention in normal healthy adults, as well as changes associated with pathological aging.     

Nietzsche on Kant and teleology in 1868: ‘“life” is something entirely dark … ’

ABSTRACT

We know from Nietzsche’s posthumously published notebooks and correspondence of his plan in 1868 to compose a doctoral dissertation in philosophy on the subject of teleology in nature and the concept of the organic, with reference to Kant. The bulk of my discussion represents an attempt to extrapolate from Nietzsche’s letters and preparatory notes the view he arrived at. Since the notes do not defend explicitly any single definitive thesis, their interpretation is unavoidably conjectural. I argue that, if Nietzsche’s remarks are considered with close reference to the philosophers who at that point dominated his horizons, namely Kant, Schopenhauer, and Lange, with Goethe also playing a key role, a plausible account can be given of the broad conclusions Nietzsche reached as a result of his early engagement with the problem of teleology. This outlook maintains the necessity and distinctiveness of philosophical reflection, but takes a skeptical view of its basis. In 1868 Nietzsche had no clear idea of how to proceed from this point, but in the end I propose, as others have done, that Nietzsche’s reflections on Kant and teleology helped to lay the ground for The Birth of Tragedy. In conclusion, I hypothesize that Nietzsche’s later philosophy involves no change of metaphilosophical standpoint.     

Concurrent and incremental validity of three trait emotional intelligence measures

This study explored concurrent and incremental validity of three trait emotional intelligence measures: the Schutte Emotional Intelligence Scale, Multidimensional Emotional Intelligence Assessment, and Trait Emotional Intelligence Questionnaire. A total of 307 participants were drawn predominantly from community and student populations. Concurrent criterion validity of the measures varied depending on whether emotional intelligence (EI) was assessed as a lower, middle or higher level construct, with validity coefficients being larger for the former. In all cases, the Trait Emotional Intelligence Questionnaire was the superior predictor of multiple psychological criteria. At the higher level of assessment, incremental validity beyond (a) age, gender and the Big Five, and (b) the remaining two EI measures, was also superior.
