Familial transmission of Continuous Performance Test behavior: attentional and impulsive response characteristics

Continuous Performance Tests (CPTs) provide information on attentional processing and impulsive behavior. The results of previous research that used self-report measures have provided evidence for familial transmission (through genetic and/or environmental influences) of impulsive characteristics. The authors of the present study examined whether the impulsive behavioral parameters that are measured by the CPT also share familial relationships. The researchers asked 26 healthy parent-adolescent pairs to complete the Immediate and Delayed Memory Tasks (IMT/DMT; D. M. Dougherty, 1999; D. M. Dougherty, D. M. Marsh, & C. W. Mathias, 2002), a modified CPT (B. A. Cornblatt, N. J. Risch, G. Faris, D. Friedman, & L. Erlenmeyer-Kimling, 1988; H. E. Rosvold, A. Mirsky, I. Sarason, E. D. Breansome, Jr., & L. H. Beck, 1956), and the Barratt Impulsiveness Scale (BIS; J. H. Patton, M. S. Stanford, & E. S. Barratt, 1995), a self-report measure. The main findings can be summarized as follows: (a) commission errors (but not correct detections) on the IMT and DMT were correlated between parents and their adolescent children, (b) adolescents emitted a higher proportion of commission errors than did their parents, and (c) self-reported impulsivity (i.e., BIS) was correlated with commission errors for parents, but not for adolescents. The findings of this study support the use of an objective behavioral measure of impulsivity to assess familial relationships of impulsivity.     

TPL—KATS-card sort: A tool for assessing structural knowledge

The study of how individuals organize knowledge has been a popular endeavor for several decades. As a result, techniques have been developed to assess how individuals represent and organize knowledge internally. Although several conceptual knowledge elicitation methods have been developed and used to assess the organization of knowledge, their use is often labor intensive and time consuming. Presented here is a software tool that was developed to reduce the problems associated with manually administering the conceptual knowledge elicitation technique, or card sorting. The TPL—KATS-card sort software not only simplifies the administration of the task, but also adds features to the card-sorting task such as media insertion, time stamping, and instructorless administration. In the present article, an introduction to the card-sorting technique is provided, the new software tool is described, and the advantages of the software are detailed.     

Reducing stereotype threat in urban schools

Research suggests student performance may be negatively influenced by stereotype threat, “being at risk of confirming, as self-characteristic, a negative stereotype about one’s group” (Steele and Aronson in J Personal Soc Psychol 69(5):797, 1995). However, studies have also found that educating students about stereotype threat and the nature of intelligence can attenuate its effects. This paper explored whether a brief intervention could improve performance and attitudes for 109 at-risk students in a large urban school. Results found the intervention did not result in statistically significant differences in grades, or increases in student beliefs about their ability to succeed in school. Educational implications are discussed.     

Behavioral Variability in the Play of Children With Autism and Their Typically Developing Peers

Invariable or repetitive behavior is a defining feature of autism and can limit a child's exposure to varying consequences and subsequent learning opportunities. We compared the variability in play material selection between 30 children with autism and 30 typically developing children, aged 2‐8 years, across three different activities: selecting paper outfits to dress dolls, selecting beads to place on a string, and choosing marker colors for coloring shapes. Selections of materials could be varied or identical to previous selections within the session. Although there was some overlap between the two groups, children with autism were more likely to respond invariably than typically developing children. Two‐year‐old children in both groups tended to display invariable play material selection, but variability increased across increasing age groups for typical children and remained relatively stable across increasing age groups for children with autism. Implications regarding the divergence in variable behavior across children with autism and typically developing children as a function of age are discussed.

The effect of Parkinson's disease on time estimation as a function of stimulus duration range and modality

The present research sought to investigate the role of the basal ganglia in timing of sub- and supra-second intervals via an examination of the ability of people with Parkinson's disease (PD) to make temporal judgments in two ranges, 100-500 ms, and 1-5 s. Eighteen non-demented medicated patients with PD were compared with 14 matched controls on a duration-bisection task in which participants were required to discriminate auditory and visual signal durations within each time range. Results showed that patients with PD exhibited more variable duration judgments across both signal modality and duration range than controls, although closer analyses confirmed a timing deficit in the longer duration range only. The findings presented here suggest the bisection procedure may be a useful tool in identifying timing impairments in PD and, more generally, reaffirm the hypothesised role of the basal ganglia in temporal perception at the level of the attentionally mediated internal clock as well as memory retrieval and/or decision-making processes.     

Screening and assessment of psychosocial dysfunction in a private pediatric practice

Fifty-one mother-infant pairs were screened at birth and at one month of age using the Neonatal Perception Inventories (NPI). This instrument identified 20 infants who were judged at high risk for the development of subsequent emotional disorder. Evaluation of the study group at 14–17 months of age, using the Infant Mental Health Profile, documented impairment in the areas of attachment, confidence and coping in 80–95% of those infants with high risk NPI ratings. The use of the NPI as a screening instrument in a primary care private pediatric setting is discussed.     

Are Categorical Deniers Different? Understanding Demographic,Personality, and Psychological Differences between Denying and Admitting Individuals with Sexual Convictions

ABSTRACT

The purpose of this study was to establish whether there were demographic, personality, or psychological differences between a sample of 40 incarcerated sex offenders in categorical denial and 37 sex offenders admitting responsibility in an Australian minimum-security unit. Categorical deniers had lower IQs, were older, and were more likely to be child molesters. Criminogenically, there were no differences between categorical deniers and those who admitted their offences in relation to Static-99 risk scores. Psychologically, offenders denying their offences were significantly more shame-prone, and likely to use externalization as a method of impression-management. They were also more compulsive than those admitting their offences, but less antisocial and sadistic, when compared on personality indices. The study is limited by the small sample size however implications for further research and the treatment of categorical deniers are discussed.
