Assessing Effort During Neuropsychological Evaluation with the TOMM in Children and Adolescents with Epilepsy

Effort assessment is of particular importance in pediatric epilepsy where neuropsychological findings may influence treatment decisions, especially if surgical interventions are being considered. The present investigation examines the Test of Memory Malingering (TOMM) in 60 children and adolescents with epilepsy. The overall pass rate for the sample was 90%. TOMM scores were unrelated to age, though there was a significant correlation between TOMM Trial 2 scores and intelligence estimates. Overall, the TOMM appears to be a valid measure of effort in young epilepsy patients, though caution should be used when interpreting scores for those with very low IQ, especially if behavioral problems are also evident. Caution should also be exercised in interpreting scores in children with ongoing interictal epileptiform activity that may disrupt attention.     

The Role of Syllable Awareness and Syllable-Controlled Text in the Development of Finger-Point Reading

Concept of word is a pivotal developmental insight that is reflected when preliterate learners are able to repeat a line of print and accurately point to the words while saying them (finger-point reading) and relocate a specific word within that line (word finding). Several studies have shown that letter knowledge, phonemic skills, one-to-one correspondence, and spelling relate to finger-point reading. However, no studies have examined the relationship between syllable awareness and finger-point reading despite the fact that finger-point reading requires learners to handle multisyllabic words. With a group of young children this study examined: (a) the influence of syllable-controlled text on learning finger-point reading and (b) the degree to which syllable awareness would contribute to the prediction of finger-point reading above letter naming and initial sound awareness. Syllable-controlled text did not influence finger-point reading but syllable awareness did predict a significant proportion of the variance in finger-point reading over and above letter knowledge and initial sound awareness. Implications of the interactive nature of phonological and print knowledge are discussed as well as capacity of young children to learn about print.     

Atrophy of the parietal lobe in preclinical dementia

Cortical grey matter atrophy patterns have been reported in healthy ageing and Alzheimer disease (AD), but less consistently in the parietal regions of the brain. We investigated cortical grey matter volume patterns in parietal areas. The grey matter of the somatosensory cortex, superior and inferior parietal lobule was measured in 75 older adults (38 cognitively stable and 37 individuals with cognitive decline after 3 years). Dementia screening 6 years after scanning resulted in nine AD cases from the cognitively stable (n=3) and cognitive decline group (n=6), who were assigned to a third group, the preclinical AD group. When regional differences in cortical volume in the parietal lobe areas were compared between groups, significant differences were found between either the cognitive decline or stable group on the one hand and preclinical AD individuals on the other hand in the inferior parietal lobule. Group membership was best predicted by the grey matter volume of the inferior parietal lobule, compared to the other parietal lobe areas. The parietal lobe was characterised by a differential atrophy pattern based on cognitive status, which is in agreement with the 'last-developed-first-atrophied' principle. Future studies should investigate the surplus value of the inferior parietal lobe as a potential marker for the diagnosis of AD compared to other brain regions, such as the medial temporal lobe and the prefrontal lobe.     

Socialization of past event talk: Cultural differences in maternal elaborative reminiscing

This study examines mother-child reminiscing conversations with respect to variation in use and function of mothers’ elaborations, the nature of children's memory elaborations, and the connections between the two, in three Western middle-class cultures where autonomy is valued over relatedness. Mothers participated with their 4-year-old children (35 dyads from Berlin, Germany, 42 dyads from Stockholm, Sweden, and 38 from Tallinn, Estonia). Mothers’ open-ended questions predicted children's memory elaborations in Estonian dyads, mothers’ statements and verbal confirmation did so in German dyads, and verbal confirmations did so in Swedish dyads. Number of children's elaborations was similar in all three groups, but Estonian mothers were less elaborative than Swedish and German mothers. These findings contrast with previous research in which number of child elaborations has been linked to number of mother elaborations. The results suggest that different aspects of elaborative style function differently. The differences are discussed in light of culturally rooted meanings and practices of talking.     

Pygmalion in the laboratory

Testers and bystanders can inadvertently lead subjects to answers in laboratories and in classrooms, in face-to-face tests of human beings and other animals. Many modern investigators avoid leading by using blind tests scrupulously. This article shows how to design blind tests and illustrates common methodological errors that allow leading to confound experimental results. The object is to help experimenters, editors, and readers detect and avoid a common experimental error that often has profound theoretical implications.     

Using Sexual Appeals in Advertising to Sell Cosmetic Surgery: A Content Analysis from 1986 to 2007

This study provides an account of how sexual appeals are used to promote cosmetic surgery. A content analysis of advertisements appearing between 1986 and 2007 in large city magazines reveals that advertisements position surgery as a means of boosting sex-esteem, and enhancing one’s sexual attractiveness, a pattern different from that of branded consumer products and services. Invasive procedures such as liposuction and breast augmentation are the top procedures advertised with sexual appeals and most advertisements feature nude or partially-nude white female models. The findings help expand knowledge about cosmetic surgery advertising, how sex is used to sell an ideal beauty standard attainable through invasive medical services, and the use of sexual content in a new context, that of medical-related advertising for cosmetic surgery.     

A hit-and-miss investigation of asymmetries in wheelchair navigation

In contrast to the leftward inattention caused by right parietal damage, normal brain function shows a subtle neglect of the right and left sides in peripersonal and extrapersonal space, respectively. This study explored how these attentional biases cause healthy individuals to collide with objects on the right. In Experiment 1, participants navigated manual and electric wheelchairs through a narrow doorway. More rightward collisions were observed for the electric, but not the manual, wheelchair. Experiment 2 demonstrated that the rightward deviation for electric wheelchairs increased for wider doorways. Experiment 3 established that the rightward deviation is not the result of task-related vestibular input, using a remote control device to operate the wheelchair. The rightward deviation persisted in Experiment 4 when the doorway was removed, suggesting that the bias is the result of a mis-bisection of space. In Experiment 5, the rightward bias was replicated using an electric scooter, which is steered using handlebars. Finally, Experiment 6 required participants to point to the middle of the doorway, using a laser, before moving the scooter. Rightward mis-bisection was observed in both conditions. Rightward mis-bisection of lines in extrapersonal space provides the most parsimonious explanation of the rightward collisions and deviations.     

Anxious Solitude and Clinical Disorder in Middle Childhood: Bridging Developmental and Clinical Approaches to Childhood Social Anxiety

It was hypothesized that children identified by their peers at school as anxious solitary would report more symptoms of social anxiety disorder on a self report questionnaire and, on the basis of child and parent clinical interviews, receive more diagnoses of social anxiety disorder and additional anxiety and mood disorders. Participants were 192 children drawn from a community sample of 688 children attending public elementary schools. Half of these children were selected because they were identified as anxious solitary by peers and the other half were demographically-matched controls. 192 children provided self reports of social anxiety disorder symptoms on a questionnaire, and 76 of these children and their parent participated in clinical interviews. Results indicate that children identified by their peers as anxious solitary in the fall of 4th grade, compared to control children, were significantly more likely to receive diagnoses of social anxiety disorder, specific phobia, and selective mutism based on parent clinical interviews. Additionally, there was a tendency for these children to be diagnosed with generalized anxiety disorder and post traumatic stress disorder based on parent clinical interviews. Furthermore, children who had been identified as anxious solitary at any time in the 3rd or 4th grades were more likely than control children to report symptoms of social anxiety disorder that fell in the clinical range and to receive diagnoses of social anxiety disorder and dysthymia (both trends) and major depression (a significant effect) according to parental clinical interview.
