The nature of sexual offenders' affective empathy: a grounded theory analysis.

The aim of this research was to investigate the nature of sexual offenders' affective empathy. Thirty-one men participating in a residential treatment program for child abusers constructed "victim apology letters" as a way of measuring/examining empathy deficits. The task was videotaped, transcribed, and subject to grounded theory techniques. It was discovered that intrafamilial offenders were more likely to minimize their behavior while exhibiting illicit power and control, whereas extrafamilial offenders were more likely to directly blame their victims and exhibit overtly explicit offense detail. From these open-coded categories, the axial categories of self as nonoffender, external blaming, and secondary victimization were derived. These results may have implications for the delivery of victim empathy components of sexual offender treatment programs.

Reduced cognitive inhibition in obsessive-compulsive disorder.

On a semantic negative priming task designed to investigate putative inhibitory mechanisms of selective attention, obsessive-compulsive disordered (OCD) subjects were distinguished from all other sub-categories of anxiety disorder (OAD). OCD subjects failed to show any priming effects in the repetition priming condition and exhibited facilitation in the semantic priming condition (i.e. shorter reaction times to previously ignored stimuli). OAD subjects demonstrated negative priming (i.e. longer reaction times to previously ignored stimuli) in both experimental conditions. These results are interpreted in terms of reduced cognitive inhibition in OCD and the implications of this hypothesis are discussed. Parallels are also drawn with previous studies regarding the results of high schizotypes and schizophrenic subjects using negative priming tasks.

Lateralization of the 'negative priming' effect: relationships with schizotypy and with gender.

An investigation is reported of a divided visual field version of a negative priming task of selective attention, performance on which has previously been shown to be related to schizotypal personality traits. In lateralized form the task produced a significant interaction between schizotypy and visual field, and an influence of gender. Among males high schizotypes showed an absence of negative priming after primes presented to the left visual field. However, right field primes produced slightly more negative priming than in low schizotypes, who showed strong negative priming effects under both conditions. Among females there was less negative priming overall, no difference between visual fields, and no association with schizotypy. The results are interpreted in the light of evidence from other hemisphere research about lateralization of language in schizotypy and schizophrenia.

Obsessional states: anxiety disorders or schizotypes? An information processing and personality assessment.

This paper presents evidence that on an information processing task, designed to investigate putative inhibitory mechanisms in selective attention, obsessive-compulsive disordered individuals can be clearly distinguished from other anxiety disorder clients and show significantly higher scores on questionnaire measures designed to detect schizotypy in the normal population. It is suggested that these results provide some support for the idea that obsessive-compulsive disorder may be misclassified as an anxiety disorder and may in fact be categorically more closely aligned to the schizophrenic constellation of disorders.

The cerebral hemispheres and bilateral neural nets.

A high-level cognitive dichotomy ("language and context") is reviewed in relation to empirical findings concerning the functions of the human cerebral hemispheres. We argue that the right hemisphere's involvement in the generation of connotative and contextual information in parallel with the denotative and literal language functions of the left hemisphere provides an important insight into the organization of viable cognitive systems. The role of the corpus callosum in producing the dichotomy is discussed. Finally, the generation of asymmetrical activity in structurally symmetrical, bilateral neural nets is described. The model demonstrates how complementary memory states can be generated in bilateral nets without assuming different modes of information processing, provided that the nets have inhibitory, homotopic connections. Unlike excitatory connections, inhibitory connections are sufficient to generate asymmetric hemispheric activity without postulating intrinsic differences between the cerebral hemispheres.
