Learning Disabilities and Delinquent Behaviors among Adolescents: A Comparison of Those with and without Comorbidity

Research is inconclusive on whether adolescents with learning disabilities (LD) engage in more delinquency than adolescents without such deficits. Mixed results may result from a failure to account for the effects of co-occurring disabilities. Using the National Longitudinal Study of Adolescent Health, this study examines delinquency among adolescents without disabilities to youth with LD, Attention Disorder Symptoms (ADS), and comorbid LD/ADS. Results indicate no significant differences in property offenses, or alcohol, tobacco, and marijuana use; however, youth with LD reported significantly more violence than non-disabled youth. Findings illustrate the heterogeneous effects various disabilities have on delinquent behavior. Future research and policy implications will be discussed.     

Intuition as a Basic Source of Moral Knowledge

The idea that intuition plays a basic role in moral knowledge and moral philosophy probably began in the eighteenth century. British philosophers such as Anthony Shaftsbury, Francis Hutcheson, Thomas Reid, and later David Hume talk about a “moral sense” that they place in John Locke’s theory of knowledge in terms of Lockean reflexive perceptions, while Richard Price seeks a faculty by which we obtain our ideas of right and wrong. In the twentieth century intuitionism in moral philosophy was revived by the works of G. E. Moore, H. A. Prichard, and W. D. Ross. These philosophers reject Kantian deontological ethics and utilitarianism insisting that intuition is the only source of moral knowledge. Recently, there is a renewed interest in intuition by philosophers doing meta-philosophy by reflecting on what philosophers do, and why they disagree. In this essay we plan to take some of this recent literature on intuition and apply it to moral philosophy. We will proceed by (1) defining a conception of intuition, (2) answering some skeptical challenges, (3) delimiting its target, and (4) arguing that intuition is often a source of moral knowledge.

"Solar love": Nietzsche,Merleau-Ponty and the fortunes of perception

Both Nietzsche and Merleau-Ponty repudiate the mirror view of perception and embrace what Nietzsche refers to as solar love or creative perception. I argue that Merleau-Ponty thinks of this type of perception primarily in terms of convergence and Nietzsche in terms of divergence. I then show how, contrary to their own emphases, Merleau-Ponty's notion of flesh and Nietzsche's idea of chaos suggest that convergence and divergence are abstractions from an ontologically prior realm of hybrid perceptions. In this realm, each perception is shot through with the others, simultaneously inside and outside one another. The creative tension among these perceptions continually produces new perspectives or voices, that is, a realm whose very being is metamorphosis. Moreover, this realm of hybrid perceptions suggests a political principle that might prove attractive for communities in an age of diversity and cultural hybridity.     

The role of the orbitofrontal cortex in normally developing compulsive-like behaviors and obsessive-compulsive disorder

Mounting evidence concerning obsessive-compulsive disorders points to abnormal functioning of the orbitofrontal cortices. First, patients with obsessive-compulsive disorder (OCD) perform poorly on tasks that rely on response suppression/motor inhibition functions mediated by the orbitofrontal cortex relative to both normal and clinical controls. Second, patients with OCD exhibit functional hyperactivity in lateral orbitofrontal and related structures corresponding with symptom severity. In this article, we compare these neurocognitive correlates of OCD with the executive and neural underpinnings of "compulsive-like" behaviors that are common in normal childhood. We discuss the phenomenology and natural history of normative compulsive-like behaviors as well as the behavioral, emotional, and cognitive continuities between typical and pathological obsessive-compulsive behaviors. We then examine associations between children's executive performance deficits and their observed compulsive-like characteristics. We relate these patterns to executive deficits shown by adults with OCD. Finally, we speculate on the developmental neurobiology of children's compulsive-like behaviors, with particular attention to orbitofrontal functions including behavioral and emotional regulation, and we suggest similarities and differences with the neurobiology of OCD. In making these comparisons, we hope to open a dialogue between researchers who study underlying brain pathologies associated with OCD and those who explore the neurocognitive bases of normal development.     

The Individualised Patient‐Progress System: A decade of international collaborative networking

Background: The backstage of research projects is seldom presented to the general audience, in particular, how the research questions emerged, how the team interacted and how the methods and design were decided upon. Aim: In this paper we will recount the story behind an international practice‐based research network for personalising health assessment, the joint journey of researchers and therapists from three different countries in creating the Individualised Patient‐Progress System (IPPS). Results: We first describe how the idea of the IPPS emerged; then we show how IPPS is being piloted and integrated into clinical practice. Next, we present the views of therapists and researchers who have been part of this project. Conclusions: We discuss some lessons learned from this 14‐year collaborative research programme.     

Perceptual processing of adjacent and nonadjacent tactile nontargets.

Previous research has shown that subjects appear unable to restrict processing to a single finger and ignore a stimulus presented to an adjacent finger. Furthermore, the evidence suggests that, at least for moving stimuli, an adjacent nontarget is fully processed to the level of incipient response activation. The present study replicated and expanded upon these original findings. The results of Experiment 1 showed that an equally large response-competition effect occurred when the nontarget was presented to adjacent and nonadjacent fingers (on the same hand). The results of Experiment 2 showed that the effects observed in Experiment 1 (and in previous studies) were also obtained with stationary stimuli. Although small, there was some indication in the results of Experiment 2 that interference may dissipate more rapidly with distance with stationary stimuli. An additional finding was that interference effects were observed in both experiments with temporal separations between the target and nontarget of up to 100 msec. In Experiment 3, target and nontarget stimuli were presented to opposite hands. Although reduced, interference was still evident with target and nontarget stimuli presented to opposite hands. Varying the physical distance between hands did not produce any change in the amount of interference. The results suggest that the focus of attention on the skin extends nearly undiminished across the fingers of one hand and is not dependent upon the physical distance between sites of stimulation.     

Salivary Cortisol as a Biomarker in Social Science Research

Cortisol, a neuroendocrine hormone measurable in saliva, responds to internal and external triggers. In providing a peripheral ‘window on the brain’, it has been increasingly incorporated into social psychological studies. Cortisol secretion can be studied in two main ways, examination of acute stress reactivity and examination of the basal circadian patterns. These can inform aspects of acute and chronic stress exposure and relationships with health. Within non‐clinical populations, cortisol effects are largely driven by differences in the perception of threat. For social psychologists, this provides an interesting avenue for the investigation of social factors that mediate perceptions of threat, such as social support, relationship processes, and group dynamics in acute and chronic stress. This paper provides a background to understanding the regulation and function of cortisol, and issues arising in relation to its measurement in saliva. It discusses and makes recommendations on the use of appropriate cortisol measures in the study of both acute and chronic stress. Used and interpreted appropriately, stress reactivity and basal ambulatory measures of salivary cortisol can provide a valuable adjunct to self‐report and observation in social psychological research. © 2013 John Wiley & Sons Ltd     

Temperament and personality: origins and outcomes

This article reviews how a temperament approach emphasizing biological and developmental processes can integrate constructs from subdisciplines of psychology to further the study of personality. Basic measurement strategies and findings in the investigation of temperament in infancy and childhood are reviewed. These include linkage of temperament dimensions with basic affective-motivational and attentional systems, including positive affect/approach, fear, frustration/anger, and effortful control. Contributions of biological models that may support these processes are then reviewed. Research indicating how a temperament approach can lead researchers of social and personality development to investigate important person-environment interactions is also discussed. Lastly, adult research suggesting links between temperament dispositions and the Big Five personality factors is described.     

Stress and open-office noise

Forty female clerical workers were randomly assigned to a control condition or to 3-hr exposure to low-intensity noise designed to simulate typical open-office noise levels. The simulated open-office noise elevated workers' urinary epinephrine levels, but not their norepinephrine or cortisol levels, and it produced behavioral aftereffects (fewer attempts at unsolvable puzzles) indicative of motivational deficits. Participants were also less likely to make ergonomic, postural adjustments in their computer work station while working under noisy, relative to quiet, conditions. Postural invariance is a risk factor for musculoskeletal disorder. Although participants in the noise condition perceived their work setting as significantly noisier than those working under quiet conditions did, the groups did not differ in perceived stress. Potential health consequences of long-term exposure to low-intensity office noise are discussed.     

Person-specific paths of cognitive decline in Alzheimer's disease and their relation to age

Change in global and specific measures of cognitive function was studied in a cohort of 410 persons with Alzheimer's disease. Persons completed up to 5 annual evaluations; follow-up participation among survivors exceeded 90%. Average annual decline was 0.57 standard score units (95% confidence interval [CI]: -0.51 to -0.62) on a composite measure based on 17 individual tests and 3.26 points (95% CI: -3.06 to 3.46) on the Mini-Mental State Examination, but substantial heterogeneity was apparent. On both global and specific measures, rate of cognitive decline was reduced in older persons compared with younger persons. A similar effect was observed for estimated age of disease onset. The effect of age was approximately linear and was not attributable to education, sex, race, other conditions that impair cognition, or mortality. The results indicate that person-specific paths of cognitive decline in Alzheimer's disease vary substantially and suggest that in clinical settings some of this variability is related to age.
