Neurocognitive Performance in Children with ADHD and OCD

Attention-deficit/hyperactivity Disorder (ADHD) and obsessive–compulsive disorder (OCD) have both been linked to dysfunction in the cortico-striato-thalamo-cortical circuitry (CSTCC). However, the exact nature of neurocognitive deficits remains to be investigated in both disorders. We applied two neuropsychological tasks that tap into different functions associated with the CSTCC, namely a serial reaction time (SRT) task, developed to assess implicit sequence learning, and a delay aversion (DA) task in order to assess abnormal motivational processes. The performance data of boys with ADHD (n = 20), OCD (n = 20) and healthy controls (n = 25), all aged 10–18 years, were compared. Subjects with ADHD less frequently chose the larger, more delayed reward compared to those with OCD and controls, while subjects with OCD showed impaired implicit learning. In contrast, the ADHD group was unimpaired in their implicit learning behavior and the OCD group was not characterized by a DA style. Within the OCD-group, severity of obsessions was associated with implicit learning deficits and impulsive symptoms with DA in the ADHD-group. This double dissociation highlights the distinct cognitive dysfunctions associated with ADHD and OCD and might possibly point to different neural abnormalities in both disorders.     

Predictive Validity of the Suicide Probability Scale in a Male Inmate Population

This paper describes the predictive power of the Suicide Probability Scale (SPS) within a male inmate population. The SPS scores of 1,047 inmates from 1995 to 1996 were compared against their suicidal behaviors in the following 10 years. The SPS probability score and the scores on its four subscales were found to be significantly higher in the group that engaged in at least one of three types of suicidal behavior: suicide, non-lethal self-harm and serious suicidal intentions. However, the SPS did not discriminate the inmates who went on to commit suicide. The SPS’s capacity to predict suicidal behavior proved limited in terms of sensitivity. In this regard, the SPS’s low and high risk levels correctly identified 36% of inmates who later engaged in suicidal behavior. The specificity was 0.85. These results confirm the SPS’s predictive power with male prisoners. These findings are the first to demonstrate the predictive validity of the SPS.     

Betting Against Compatibilism

Some argue that libertarianism represents the riskier incompatibilist view when it comes to the free will problem. An ethically cautious incompatibilist should bet that we are not free in the sense required for moral responsibility, these theorists claim, as doing so means that we no longer run the risk of holding the morally innocent responsible. In this paper, I show that the same reasoning also advises us to bet against compatibilism. Supposing that we are unsure about whether or not the causal order of the world is compatible with the kind of freedom that is required for moral responsibility, an ethically cautious approach would once again bet that hard incompatibilism is true.     

Accumulative Equating Error after a Chain of Linear Equatings

After many equatings have been conducted in a testing program, equating errors can accumulate to a degree that is not negligible compared to the standard error of measurement. In this paper, the author investigates the asymptotic accumulative standard error of equating (ASEE) for linear equating methods, including chained linear, Tucker, and Levine, under the nonequivalent groups with anchor test (NEAT) design. A recursive formula for the ASEE is provided for a series of equatings that makes use of only historical summary statistics. This formula can serve as a new tool to measure the magnitude of equating errors that have accumulated over a series of equatings, and to help monitor and design testing programs.     

What Punishment for the Murder of 10,000?

Those who commit crime on a grand scale, numbering their victims in the thousands, seem to pose a special problem both for consequentialist and for non-consequentialist theories of punishment, a problem the International Criminal Court makes practical. This paper argues that at least one non-consequentialist theory of punishment, the fairness theory, can provide a justification of punishment for great crimes. It does so by dividing the question into two parts, the one of proportion which it answers directly, and the other of ‘anchoring points’ which it assigns to a broader theory of enforcement (which may have a non-consequentialist or consequentialist version).     

The change-of-standard effect: Distorted standards and adjusted impressions

Previous accounts of the memory distortion known as the change-of-standard effect hypothesize that participants form a relative impression of a target at encoding and later use that impression with the average of all items to recall the target (Higgins & Lurie, 1983). In three experiments, we investigated the standard and the integration of the standard with the relative impression. Experiments 1 and 2 show that participants’ subjective average at recall is distorted toward recent stimuli: It is computed when required and is therefore affected by the items’ accessibility at that time. Furthermore, the impression’s influence on recall is relatively small when the context changes between encoding and decoding. Experiment 3 shows that this change in the impression’s influence occurs only when the participant integrates information across sessions, suggesting that such tasks make participants aware of the changed context and cause them to adjust the use of their impression in recalling the target.     

Bare’ing it all for the Camera: Women’s Experience of Having Erotic Photographs Taken

One area in which a change in women’s sexual behavior has been observed is in the growing number of women who are having erotic photographs taken of themselves by professional photographers. The current research is an attempt to learn more about this unstudied phenomenon. In-depth, semi-structured interviews were conducted with 16 women who have had erotic photographs taken by a professional photographer. The interviews were subjected to thematic analysis. The women described the erotic photography experience as having positive implications, such as increased body esteem and feelings of empowerment, as well as giving the women the ability to see themselves as sexual and an opportunity to celebrate their bodies. Having erotic photos taken also provided women with the opportunity to create a sexual image in a photograph on their own terms. The findings provide insight into the changing nature of attitudes about women’s sexuality.     

Decreased Sensitivity to Phonemic Mismatch in Spoken Word Processing in Adult Developmental Dyslexia

Initial lexical activation in typical populations is a direct reflection of the goodness of fit between the presented stimulus and the intended target. In this study, lexical activation was investigated upon presentation of polysyllabic pseudowords (such as p rocodile for crocodile) for the atypical population of dyslexic adults to see to what extent mismatching phonemic information affects lexical activation in the face of overwhelming support for one specific lexical candidate. Results of an auditory lexical decision task showed that sensitivity to phonemic mismatch was less in the dyslexic population, compared to the respective control group. However, the dyslexic participants were outperformed by their controls only for word-initial mismatches. It is argued that a subtle speech decoding deficit affects lexical activation levels and makes spoken word processing less robust against distortion.
