This study explored regression patterns in 100 children with ASD (3-11 years) using several approaches to enhance the validity of retrospective parent report. Both early development and outcome were examined in regression groups defined by 36 months age cut-off and two underlying empirical patterns based on type and onset age. Results over…

Background: There is limited research into the nature and aetiology of temper outbursts in people with intellectual disabilities. In this study, we describe the phenomenology and environmental context of temper outbursts in Lowe syndrome, a rare genetic syndrome in which outbursts are purportedly frequent. Method: A temper outburst interview (TOI)…

Repetitive behaviors are observed in autism spectrum disorder and obsessive-compulsive disorder. Clinically, obsessive-compulsive disorder obsessions are thought to drive repetitive or ritualistic behavior designed to neutralize subjective distress, while restricted and repetitive behaviors are theorized to be reward- or sensory-driven. Both…

Negation is a universal component of human language; polarity sensitivity (i.e., lexical distributional constraints in relation to negation) is arguably so while being pervasive across languages. Negation has long been a field of inquiry in psychological theories and experiments of reasoning, which inspired many follow-up studies of negation and…

This study assessed the potential short-term effects of COVID-19 stay-at-home restrictions on ratings of ASD and comorbid symptoms severity and adaptive functioning of 69 youth, ages 8-16 years with ASD without intellectual disability. Parent/caregiver ratings were being collected in fall and spring over approximately two years when the…

The aim of this study is to investigate the impact of the body mass index in children between the ages of 7-10 on their physical activity levels. The target population of the study is children between the ages of 7 and 10. The sample population consists of children between the ages of 7 and 10 who continue their primary education in various…

Educational Robotics in Greece is being used increasingly, while it is hesitantly applied in Special Education as it requires a properly educational trained staff. The present study is a case study aiming to discuss the effects of the utilization of educational robotics in a Special Education School classroom and specifically on students with…

Individuals track probabilities, such as associations between events in their environments, but less is known about the degree to which experience--within a learning session and over development--influences people's use of incoming probabilistic information to guide behavior in real time. In two experiments, children (4-11 years) and adults…

Cognitive effort is costly and this cost likely influences the activities in which children engage. Yet, little is known about how school-age children perceive cognitive effort. The subjective value of cognitive effort, that is, how valuable or costly effort is perceived, was investigated in seventy-three 7- to 12-year-olds using an effort…

To identify quantitative indicators of social communication dysfunctions, we explored the oculomotor performances in subjects with autism spectrum disorders. Discordant findings in the literature have been reported for oculomotor behavior in subjects with autism spectrum disorders. This study aimed to explore reflexive and voluntary saccadic…

Theory of mind refers to the ability to attribute beliefs to oneself and others. The present study used a dynamic systems approach to assess how environment may affect the development of second-order theory of mind (e.g., "John knows that Mary knows that he went out yesterday"). Theory of mind is divided into two major dimensions:…

This study assessed the potential short-term effects of COVID-19 stay-at-home restrictions on ratings of ASD and comorbid symptoms severity and adaptive functioning of 69 youth, ages 8-16 years with ASD without intellectual disability. Parent/caregiver ratings were being collected in fall and spring over approximately two years when the…

Background: The present study aimed at investigating mother-child dyadic co-regulation patterns in dyads with children with intellectual disability (ID). Method: 24 children paired for developmental age and vocabulary size (8 with chromosome 14 aberrations, 8 with Down syndrome, and 8 with typical development) and their mothers participated in the…

Purpose: Specific language impairment (SLI) affects many children, but its symptomatology is still being characterized. An emerging view, which challenges the notion that SLI is specific to language, is that SLI may actually reflect a domain-general deficit in procedural learning. We explored an extension of this hypothesis that a core deficit in…

Most definitions of emotionally disturbed youngsters suggest that disturbances in the child's behavior patterns cause academic and social problems which affect the child and his peers. While the process of identification may be facilitated by operational criteria within a definition, these factors are noticeably absent from definitions of…
