The scientist’s investigation covers issues in Developmental psychology, Cognition, Nature versus nurture, Reading and Intelligence quotient. His Developmental psychology research is multidisciplinary, incorporating elements of Social environment and Phonological awareness. His Cognition research is multidisciplinary, relying on both Academic achievement, Cognitive psychology and Genetics, Heritability.
As a member of one scientific family, he mostly works in the field of Cognitive psychology, focusing on Gene–environment interaction and, on occasion, Spatial ability. His Nature versus nurture research includes elements of Genetic determinism, Reciprocity and Aggression. His work deals with themes such as Test, Mathematical ability, Multivariate analysis and Heredity, which intersect with Reading.
His primary areas of study are Developmental psychology, Cognition, Reading, Cognitive psychology and Heritability. His primary area of study in Developmental psychology is in the field of Child development. His studies deal with areas such as Early childhood, Behavioural genetics and Genetic variation as well as Cognition.
In his research on the topic of Genetic variation, Mathematical ability is strongly related with Association. His Reading study incorporates themes from Affect and Comprehension. His research in Cognitive psychology intersects with topics in Working memory, Fluency and Elementary cognitive task.
His main research concerns Developmental psychology, Reading, Association, Cognitive psychology and Cognition. The various areas that Stephen A. Petrill examines in his Developmental psychology study include Number sense, Standardized test and Anxiety. His studies in Reading integrate themes in fields like Mathematics education, Quantile regression, Econometrics and Comprehension.
The Association study combines topics in areas such as Twin study and Statistics, Sample. His Cognitive psychology research incorporates themes from Test, Working memory and Academic achievement. His Cognition study combines topics in areas such as Mathematical ability, Feature, Psychometrics, Number line and Item response theory.
Stephen A. Petrill focuses on Developmental psychology, Anxiety, Reading, Association and Mathematical anxiety. Stephen A. Petrill works in the field of Developmental psychology, namely Child development. His research on Anxiety also deals with topics like
His work on Reading comprehension as part of general Reading study is frequently connected to Academic development, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. His Mathematical anxiety research incorporates elements of Structural equation modeling, Numerosity adaptation effect, Familial transmission and Mathematical performance. His biological study spans a wide range of topics, including Psychological testing, Cognition, Cognitive test, Number line and Number sense.
