Dual Process Theory has recently been applied to Autism spectrum disorder (ASD) to suggest that reasoning by people with ASD and people with higher levels of ASD-like traits can be characterised by reduced intuitive and greater reflective processing. 26 adolescents and adults with ASD and 22 adolescent and adult controls completed an assessment of…

The aim of this study was to identify specific cognitive abilities that predict functional outcome in high-functioning adults with autism spectrum disorder (ASD), and to clarify the contribution of those abilities and their relationships. In total, 41 adults with ASD performed cognitive tasks in a broad range of neuro- and social cognitive…

Prior research has established an executive function advantage among bilinguals as compared to monolingual peers. These non-linguistic cognitive advantages are largely assumed to result from the experience of managing two linguistic systems. However, the possibility remains that the relationship between bilingualism and executive function is…

Can children reason the Bayesian way? We argue that the answer to this question depends on how numbers are represented, because a representation can do part of the computation. We test, for the first time, whether Bayesian reasoning can be elicited in children by means of natural frequencies. We show that when information was presented to fourth,…

Research was conducted to compare evidence of implicit processing in children and adults. Implicit processing was defined as inductive cognitive activities which enable people to abstract complex knowledge from the environment. The knowledge acquired is tacit; it guides subjects' behavior in various situations without the subjects necessarily…

A study investigated whether 73 adults with mental retardation had difficulty understanding emotion-descriptive concepts and whether that difficulty can be attributed to difficulty with abstract concepts. Participants performed better on nonemotion than emotion concepts measures. There were no differences between abstract and nonabstract concepts…

A study involving 31 adults with Down syndrome investigated their ability to reason. Results found they did not differ from typically developing children, matched on expressive and verbal ability, in transitivity and non-verbal analogical thinking; however, they did differ in categorical reasoning, classical verbal analogies, and short-term…

This paper reports two experimental studies of the development of time, speed and distance concepts in children. In Experiment I subjects (12 in each of four age groups: 5-, 8-, 11-year-olds, and adults) were asked to judge which of two electric trains on parallel tracks went faster, for the longer distance, or for more time. Subject's knowledge…

Two studies examined young children's ability to understand whether the actions of artifacts, insects, mammals, or humans were caused by mental or physical states. The studies suggest that children abstract specific features of action when construing its cause across disparate situations and actors. (MDM)
