Conditional Associative Learning of Spatial and Object Information in Children with Attention Deficit/Hyperactivity Disorder

The present study assessed frontostriatal mediated memory functions in children with ADHD (N = 12) and healthy control participants (N = 12) using two tests of conditional associative learning (i.e., object and spatial) that shared similar stimulus-response association structures but that differed in terms of the demands placed upon strategic processes. Children with ADHD displayed normal performance on the object learning task but were impaired on the spatial learning task that placed greater demands on internally derived strategic processes. Secondary analyses further indicated that this strategic processing impairment cannot be attributed specifically to perseverative or working memory errors but rather appears to be related to a more general inability to maintain a high degree of consistency in responding across trials. Although the results of this study must be interpreted in light of the small sample sizes, they suggest that ADHD does not produce a basic deficit in acquiring stimulus-response associations previously shown to be associated with basal ganglia dysfunction. Rather, these findings suggest that the impaired conditional associative learning performance of children with ADHD is attributable to deficits in strategic processes previously been found to be dependent upon the integrity of the prefrontal cortex.     

Poor Readers but Compelled to Read: Stroop Effects in Developmental Dyslexia

We studied a group of 24 children with dyslexia in second to fifth primary school grades by using a discrete-trial computerized version of the Stroop Color-Word Test. Since the classic Stroop effect depends on the interference of reading with color naming, one would expect these children to show no interference or, at least, less interference than normal readers. Children with dyslexia showed, however, a Stroop effect larger than normal readers of the same age. This suggests that reading, although difficult and slow, is an inescapable step that precedes naming both in poor and in normal readers.     

Fifteen-Month-Old Infants Match Vocal Cues to Intentional Actions

Fifteen-month-old infants detected a violation when an actor performed an action that did not match her preceding vocal cue: The infants looked reliably longer when the actor expressed a humorous vocal cue followed by a sweet action or expressed a sweet vocal cue followed by a humorous action, than when the vocal cue was followed by a matching action. The infants failed to detect the mismatch when one person expressed the vocal cue and another performed the action. The results suggest that by 15 months of age, infants are capable of distinguishing between two types of vocal cues and actions along the positive emotional spectrum: humor and sweetness. Furthermore, they match humorous vocal cues to humorous actions and sweet vocal cues to sweet actions only when the cues and actions are made by the same person.     

Women Court-Ordered for Domestic Violence: Improvements in Depression

A quasi-experimental design was employed to compare depression at intake and completion of a sample of primarily Latina women court-ordered to a batterer intervention program. Data were derived from the intake assessments of 112 women over 24 months. Overwhelmingly, women reported being abused by their current and former partners. Approximately 58% of the women in this sample were depressed at intake. When culturally competent, gender-appropriate treatment is given to court-ordered women, depression symptomatology may decrease to levels of normal functioning. Further research is needed to understand court-ordered women as well as how to meet their unique needs.     

Selective and faithful imitation at 12 and 15 months

Research on imitation in infancy has primarily focused on what and when infants imitate. More recently, however, the question why infants imitate has received renewed attention, partly motivated by the finding that infants sometimes selectively imitate the actions of others and sometimes faithfully imitate, or overimitate, the actions of others. The present study evaluates the hypothesis that this varying imitative behavior is related to infants' social traits. To do so, we assessed faithful and selective imitation longitudinally at 12 and 15 months, and extraversion at 15 months. At both ages, selective imitation was dependent on the causal structure of the act. From 12 to 15 months, selective imitation decreased while faithful imitation increased. Furthermore, infants high in extraversion were more faithful imitators than infants low in extraversion. These results demonstrate that the onset of faithful imitation is earlier than previously thought, but later than the onset of selective imitation. The observed relation between extraversion and faithful imitation supports the hypothesis that faithful imitation is driven by the social motivations of the infant. We call this relation the King Louie Effect: like the orangutan King Louie in The Jungle Book, infants imitate faithfully due to a growing interest in the interpersonal nature of interactions.

Jan Patočka’s sacrifice: philosophy as dissent

This article attempts to bring together the life, situation, and philosophical work of the Czech phenomenologist Jan Pato?ka in order to present his conception of philosophy and sacrifice and to understand his action of dissent and his own sacrifice as spokesman for Charter 77 in light of these concepts. Pato?ka philosophized despite being barred from teaching under the German occupation and under the communist regime, even after he was forced to retire and banned from publication. He also refused the official philosophical categories of communism and, what is more, criticized the very manner in which its ideology allowed it to function. Against the destruction of moral and political life by communist and liberal regimes alike, he outlined the necessity of a “life in the idea” that would be responsive to the notion of sacrifice. Such a position of distance from the things of the world which remains anchored among them is meant to respond to dissatisfaction with the world as it is found and is the very movement of human freedom. Taken together, these three aspects of his philosophical practice made him a dissident, a role he took on more completely when, as part of the Charter 77 movement, he publicly opposed the state, in a course of action that led to his death.     

Difference Scores in the Identification of Children with Learning Disabilities It's Time to Use a Different Method

In this article, we identify ten reasons why discrepancy scores (based on differences between IQ and reading achievement scores) provide an inadequate means for identifying children with reading disabilities. We recommend instead that children be identified simply on the basis of problems in reading skills, regardless of their IQs.
