A general factor in improvement with practice

Results of 10 trials on 6 tests for 50 subjects were analyzed, first, by applying the centroid method to actual improvement or practice scores and, second, by applying a formula developed by Woodrow for determining factor loadings for practice scores from the differences between factor loadings of initial and final scores. Contrary to expectation, the two methods yielded discrepant results, for the explanation of which a hypothesis is advanced. The operation of a general factor was not demonstrated. Tentative interpretations of the factors extracted by the centroid method are offered.     

A spectral-analysis tutorial with examples in FORTRAN

A procedure for performing spectral analysis using a digital computer is described. The relevant analysis parameters and their interaction are reviewed, and the underlying mathematical theory of the analysis is annotated with page references to a standard reference text. A computer program that implements the procedure is presented in a general form of FORTRAN. Examples of the spectra produced by a variety of input time histories are shown.     

A review of metacognition in aging with HIV

Declines in metacognitive ability occur more with aging and HIV such that some people aging with HIV may be even less able to report accurately on the status of their cognitive functioning. This is problematic because clinicians and allied health professionals rely on clients' self-reports of cognition to help judge if they are developing cognitive impairments. Such self-reports of cognition may be moderated by mood disturbance, histories of alcoholism or drug abuse, or even limited educational achievement. In this review, implications of this phenomenon and suggestions for researching this topic and assessing at-risk clients are posited.     

Psychiatric Comorbidity in Children with Autism Spectrum Disorders: A Comparison with Children with ADHD

The present study was conducted with the aim to identify comorbid psychiatric disorders in children with autism spectrum disorders (ASD) (n = 40) and to compare those comorbidity rates to those in children with attention deficit hyperactivity disorder (ADHD) (n = 40). Participants were clinically referred children aged 7–18 years. DSM-IV classifications were used for the primary diagnosis (ASD/ADHD), while comorbid psychiatric disorders were assessed using a structured diagnostic interview, the structured clinical interview for DSM-IV, childhood diagnoses (KID-SCID). Twenty-three children with ASD (57.5 %) had at least one comorbid disorder, whereas 16 children with ADHD (40.0 %) were classified as having at least one comorbid disorder. No group differences were found with respect to this comorbidity rate or for the rate of comorbid externalizing disorders (ODD and/or CD). However, children with ASD had more comorbid internalizing disorders compared to children with ADHD. More specifically, children with ASD had higher rates of anxiety disorders, but not mood disorders. No associations between comorbidity and age or between comorbidity and the intelligence quotient was found. It is important for clinicians to always be aware of, and screen for, comorbidity, and to consider treatment for these comorbid disorders. In addition, research should focus on establishing valid and reliable screening tools as well as effective treatment options for these comorbid disorders.     

A threat-detection advantage in those with autism spectrum disorders

Identifying threatening expressions is a significant social perceptual skill. Individuals with autism spectrum disorders (ASD) are impaired in social interaction, show deficits in face and emotion processing, show amygdala abnormalities and display a disadvantage in the perception of social threat. According to the anger superiority hypothesis, angry faces capture attention faster than happy faces in individuals with a history of typical development [Hansen, C. H., & Hansen, R. D. (1988). Finding the face in the crowd: An anger superiority effect. Journal of Personality and Social Psychology, 54(6), 917–924]. We tested threat detection abilities in ASD using a facial visual search paradigm. Participants were asked to detect an angry or happy face image in an array of distracter faces. A threat-detection advantage was apparent in both groups: participants showed faster and more accurate detection of threatening over friendly faces. Participants with ASD showed similar reaction time, but decreased overall accuracy compared to controls. This provides evidence for less robust, but intact or learned implicit processing of basic emotions in ASD.     

Living with Death in Rehabilitation: A Phenomenological Account

This paper uses an ongoing ethnography of childhood rehabilitation to rethink the Heideggerian phenomenology of death. We argue that Heidegger’s threefold perishing/death/dying framework offers a fruitful way to chart how young people, their parents, and practitioners address mortality in the routine management of muscular dystrophies. Heidegger’s almost exclusive focus on being-towards-death as an individualizing existential structure, rather than the social life with and around death, is at odds with the clinical experience we explore in this paper. After looking to the basic structures of Heidegger’s philosophy of death, we point to recent work by Leder, Svenaeus, Aho, and Carel, bringing health and the spaces of healthcare into our purview. Turning to ethnographic data, we argue that a revised phenomenology of death gives a nuanced account of how health care practitioners address death, dying, and perishing, and outline some steps toward a more ontologically sensitive clinical space. These revisions are in line with recent work in disability studies, that see disability as more than a death sentence. We advocate adjusting phenomenological reflections on disability, to be framed as a way of life, rather than as a deficient or especially deadly mode of human existence.

A Relational Encounter with Race

Race remains one of the most highly charged subjects of discourse in our society. At a cultural level, white racial identity has become dissociatively split off from the rest of identity formation. A racialized subjectivity is usually carried by those with darker skin colors, whereas whiteness is experienced as an unmarked and invisible state. The author argues that whites have dissociated the historical position of the oppressor from collective consciousness, due to our inability to tolerate an identification with the aggressor. Our disavowal of race as constitutive of subjectivity ensures that race becomes a site for enactments.

This paper follows the transference-countertransference dynamics between an African American patient mandated to treatment and the author, a white analyst born in South Africa. The haunting presence of racial trauma infused the analysis. Focus is placed on the rich, often unmetabolizable experiences of race, including the ways in which the structure of the treatment recreated the racial dynamics of slavery.     

与彼得·辛格的对话

对话的主题涉及辛格对马克思、全球伦理、道德责任、动物解放、伦理思维中的直觉层次与批判层次以及伦理的客观性问题。辛格哲学的特点不仅在于他始终不懈地将伦理的思维与减少痛苦与苦难的价值付诸行动,而且也在于他拓宽伦理思维的能力。辛格博采生物学、历史学、人类学、经济学以及博弈论研究成果,丰富并阐明了伦理理论与实践何以可以被现实赋予活力。当我们转向辛格的哲学时,我们会发现一种伦理的生活方式:不仅仅为此刻活着,也不仅仅根据个人喜好活着,而是去过一种具有更广意义的生活,它要求献身于所有有感受能力的生命的福祉和环境保护之中。     

A consistent way with paradox

Consideration of a paradox originally discovered by John Buridan provides a springboard for a general solution to paradoxes within the Liar family. The solution rests on a philosophical defence of truth-value-gaps and is consistent (non-dialetheist), avoids ‘revenge’ problems, imports no ad hoc assumptions, is not applicable to only a proper subset of the semantic paradoxes and implies no restriction of the expressive capacities of language.

Parental child-rearing attitudes associated with Type A behaviors in children

The relation of Type A behaviors to parental child-rearing attitudes was assessed for 177 mothers, 153 fathers, and their children in preschools. Type A behaviors of children were measured on the Japanese version of the Matthews Youth Test for Health (MYTH), and parental child-rearing attitudes were measured on the Parents' Attitudes Test (PAT). Children were classified as Type A and Type B on the basis of their MYTH scores, and parental child-rearing attitudes in the two types were compared in a combination of parental sex (mothers vs fathers) and child's sex (boys vs girls). Analysis showed that especially mothers and fathers of Type A boys had less concern for their children than their peers whose boys were classified as Type B. The notion that boys showing Type A behaviors might develop Type A behavior patterns by striving to obtain more expression of concern or affection from their parents was presented.
