The Personality Assessment Inventory as a proxy for the Psychopathy Checklist Revised: testing the incremental validity and cross-sample robustness of the Antisocial Features Scale

The Personality Assessment Inventory's (PAI's) ability to predict psychopathic personality features, as assessed by the Psychopathy Checklist-Revised (PCL-R), was examined. To investigate whether the PAI Antisocial Features (ANT) Scale and subscales possessed incremental validity beyond other theoretically relevant PAI scales, optimized regression equations were derived in a sample of 281 Canadian federal offenders. ANT, or ANT-Antisocial Behavior (ANT-A), demonstrated unique variance in regression analyses predicting PCL-R total and Factor 2 (Lifestyle Impulsivity and Social Deviance) scores, but only the Dominance (DOM) Scale was retained in models predicting Factor 1 (Interpersonal and Affective Deficits). Attempts to cross-validate the regression equations derived from the first sample on a sample of 85 U.S. sex offenders resulted in considerable validity shrinkage, with the ANT Scale in isolation performing comparably to or better than the statistical models for PCL-R total and Factor 2 scores. Results offer limited evidence of convergent validity between the PAI and the PCL-R.     

Transverse diffusivity of cerebral parenchyma predicts visual tracking performance in relapsing–remitting multiple sclerosis

This study investigated the relation between cerebral damage related to multiple sclerosis (MS) and cognitive decline as determined by two classical mental tracking tests. Cerebral damage in 15 relapsing–remitting MS patients was measured by diffusion tensor imaging (DTI). Fractional anisotropy, longitudinal and transverse diffusivity were defined in the cerebral parenchyma. Cognitive performance of the MS patients was assessed with the oral response format of the Symbol Digit Modalities Test (SDMT) and the Paced Auditory Serial Addition Test (PASAT). A significant correlation was found between performance on the SDMT and the fractional anisotropy in the brain. This correlation was predominantly induced by transverse diffusivity. Transverse diffusivity refers to the diffusion across fibers rather than along the fibers and is believed to be a specific marker for axonal loss and demyelination associated with MS. No significant association between DTI-measures and PASAT performance was found and this negative finding was mainly attributed to psychometric qualities. These results indicate that diffusivity along the non-principal diffusion direction, a possible signature of MS-related white matter pathology, contributes to information processing speed as measured with the SDMT, a task that requires close visual tracking and a widely used clinical marker for cognitive decline in MS.     

A Review of Experimental Studies of Explicit and Implicit Bias Among Counselors

Bias is a central concept in multicultural competency, but counseling research has largely ignored implicit bias. A review of bias research in counseling indicates that increased focus on implicit bias is warranted because counselors tend not to report explicit bias and have implicit bias that diverges from their self‐reported attitudes. El sesgo es un concepto esencial para la competencia multicultural, pero la investigación relacionada con la consejería ha ignorado en su mayoría el sesgo implícito. Una revisión de los estudios sobre consejería indica que está justificado aumentar la atención hacia el sesgo implícito, porque los consejeros tienden a no informar sobre el sesgo explícito y tienen sesgos implícitos que no se corresponden con sus actitudes autoinformadas     

Perelman’s Pseudo-Argument as Applied to the Creationism Controversy

If you want to challenge or at least weaken the adhesion to a system of values, you can basically adopt two radically opposed rhetorical strategies. Either you will attack the system in a frontal way: for instance, fundamentalists or fascists deny any validity to democratic values and human rights. Or you will pretend to argue from within the system (by saying that you accept some of its basic premises), while subtly distorting the process of reasoning in order to get to your conclusions. If the audience is naïve or poorly informed, you will be able to defend positions that are fundamentally at odds with liberal-democratic values while seeming to argue from inside the system. I would like to show how such a process of “perverse” translation works in the context of the Darwinism/Creationism “controversy”. The attacks on the teaching of evolutionary biology began approximately one century ago. The way Creationists have argued and changed several times their rhetorical strategies seems very interesting to me, in that it exemplifies an important contemporary phenomenon, which I call “perverse translation” or “the wolf in the sheepfold”.     

On Hatzimoysis on Sentimental Value

Despite its apparent ubiquity, philosophers have not talked much about sentimental value. One exception is Anthony Hatzimoysis (The Philosophical Quarterly 53:373–379, 2003). Those who wish to take sentimental value seriously are likely to make use of Christine Korsgaard’s ideas on two distinctions in value. In this paper I show that Hatzimoysis has misrendered Korsgaard’s insight in his discussion of sentimental value. I begin by briefly summarising Korsgaard’s idea before showing how Hatzimoysis’ treatment of it is mistaken.

Accounting for auto-dependency in binary dyadic time series data: A comparison of model- and permutation-based approaches for testing pairwise associations

Many theories have been put forward on how people become synchronized or co-regulate each other in daily interactions. These theories are often tested by observing a dyad and coding the presence of multiple target behaviours in small time intervals. The sequencing and co-occurrence of the partners’ behaviours across time are then quantified by means of association measures (e.g., kappa coefficient, Jaccard similarity index, proportion of agreement). We demonstrate that the association values obtained are not easy to interpret, because they depend on the marginal frequencies and the amount of auto-dependency in the data. Moreover, often no inferential framework is available to test the significance of the association. Even if a significance test exists (e.g., kappa coefficient) auto-dependencies are not taken into account, which, as we will show, can seriously inflate the Type I error rate. We compare the effectiveness of a model- and a permutation-based framework for significance testing. Results of two simulation studies show that within both frameworks test variants exist that successfully account for auto-dependency, as the Type I error rate is under control, while power is good.     

BROWN AND MOORE'S VALUE INVARIABILISM VS DANCY's VARIABILISM

Campbell Brown has recently argued that G.E. Moore's intrinsic value holism is superior to Jonathan Dancy's. I show that the advantage which Brown claims for Moore's view over Dancy's is illusory, and that Dancy's view may be superior.
