Epistemology and artificial intelligence

In this essay we advance the view that analytical epistemology and artificial intelligence are complementary disciplines. Both fields study epistemic relations, but whereas artificial intelligence approaches this subject from the perspective of understanding formal and computational properties of frameworks purporting to model some epistemic relation or other, traditional epistemology approaches the subject from the perspective of understanding the properties of epistemic relations in terms of their conceptual properties. We argue that these two practices should not be conducted in isolation. We illustrate this point by discussing how to represent a class of inference forms found in standard inferential statistics. This class of inference forms is interesting because its members share two properties that are common to epistemic relations, namely defeasibility and paraconsistency. Our modeling of standard inferential statistical arguments exploits results from both logical artificial intelligence and analytical epistemology. We remark how our approach to this modeling problem may be generalized to an interdisciplinary approach to the study of epistemic relations.     

Teachers' screening for attention deficit/hyperactivity disorder: comparing multinational samples on teacher ratings of ADHD

This study evaluates a measurement model for Attention Deficit/Hyperactivity Disorder (ADHD). The DSM-IV divides 18 symptoms into two groups, inattentive and hyperactive/impulsive. Elementary school teachers rated 21,161 children in 4 locations: Spain, Germany, urban US, and suburban US. Confirmatory factor analysis suggested that the 2-factor model (inattention, hyperactivity/impulsivity) shows the best fit. A third factor, impulsivity, was too slight to stand-alone. Children with academic performance problems were distinguished by inattention, but children with behavior problems typically had elevations in inattention, hyperactivity, and impulsivity. Between-site differences were statistically significant, but so small that we conclude that same measurement model fits all 4 samples in 2 continents.

Do Marital Conflict Behaviors in Response to a Novel Stressor Uniquely Predict Adolescent Outcomes?

The goal of this study was to examine whether mothers’ and fathers’ marital conflict behaviors in response to a novel stressor are uniquely predictive of adolescent outcomes. Previous research establishing the detrimental consequences of marital conflict for child outcomes has relied exclusively on assessments of conflict that measure reoccurring or past conflict. From 153 adolescents and/or both of their parents, reports were gathered on marital conflict, adolescent conflict appraisals, parent-adolescent relationship quality, and adolescent adjustment. Couples engaged in two marital problem-solving interaction tasks—one that elicited conflict behaviors by requiring discussion of salient, reoccurring topics of disagreement and one that prompted conflict behaviors by requiring that couples worked together to solve an unfamiliar problem. Results indicated that compared to behaviors during the marital conflict discussion as well as parent-reports of the frequency, intensity, and resolution of typical conflict, conflict behaviors in response to a novel stressor, particularly those displayed by mothers, were uniquely associated with adolescents’ conflict appraisals and dimensions of the parent-adolescent relationship but not adolescent adjustment. Specifically more-negative (relative to positive) conflict behaviors in response to the novel stressor was associated with more-negative adolescent conflict appraisals; mothers’ more-negative conflict behaviors in response to a novel stressor were also linked to adolescents reporting less parental monitoring. In contrast, parent reports of typical marital conflict uniquely predicted conflict property appraisals, the affective quality of mother-adolescent relationships, and adolescent adjustment. Implications for future research elucidating associations between conflict behaviors in response to a novel stressor on children and families are discussed.     

Formal Lessons Improve Informal Educational Experiences: The Influence of Prior Knowledge on Student Engagement

Educational experiences can be influenced by novel experiences, yet educators often overlook the influence novelty exerts on students. This quasi-experimental study manipulated prior knowledge before a zoo field trip for 210 urban 7^th-grade students from 2 schools, 1 comprised mostly of low-socioeconomic status (SES) families and 1 comprised mostly of middle-SES families. Students participated in 1 of 2 preparatory lessons, only 1 of which previewed field trip-related content, thereby increasing prior knowledge for half the students from each school. Prior knowledge significantly increased learner engagement, measured through attentiveness, from both schools, but in different types of behaviors. Students from the low-SES school demonstrated more attentiveness if their preparatory lesson previewed field trip material than if it was unrelated to the field trip. Students from the middle SES school displayed the same level of attentiveness in both conditions (and overall higher than the low-SES students). This study highlights complexities associated with prior knowledge and reveals strategies to help improve engagement levels for students visiting informal learning environments.     

Cognitive and attentional functioning in adolescents and young adults with Tetralogy of Fallot and d-transposition of the great arteries

The objective of this study is to investigate cognitive and attentional function in adolescents and young adults with operated congenital heart disease. Previous research has indicated that children with congenital heart disease have deficits in broad areas of cognitive function. However, less attention has been given to survivors as they grow into adolescence and early adulthood. The participants were 18 non-syndromic adolescents and young adults with tetralogy of Fallot and d-transposition of the great arteries that required cardiac surgery before the age of 5 years, and 18 healthy, unaffected siblings (11–22 years of age for both groups). Cases with congenital heart disease and their siblings were administered Wechsler Intelligence scales and reported attention problems using the Achenbach System of Empirically Based Assessments. Cases were compared to both healthy siblings and established norms. Cases performed significantly lower than siblings on full scale IQ and processing speed, and significantly lower than norms on perceptual reasoning. Cases also reported more attention problems compared to both siblings and norms. Effect sizes varied with medium-to-large effects for processing speed, perceptual reasoning, working memory, and attention problems. Findings suggest that neurocognitive function may continue to be affected for congenital heart disease survivors in adolescence and young adulthood, and that comparisons to established norms may underestimate neurocognitive vulnerabilities.
