Patients with hemispatial neglect show deficits in size perception. We investigated how this effect would be modulated by a change in object orientation. Seven right-hemisphere-lesioned patients, with and without neglect, and a control group, were asked to indicate which one of two bilaterally presented lines was longer, shorter or the same. Depending on the participant's response, the length w...

Attention deficit hyperactivity disorder (ADHD) is characterized by hyperactivity, inattention, and impulsivity. The coloboma mouse model of ADHD exhibits profound hyperactivity. To determine whether coloboma mice exhibit other signs of ADHD, we assessed latent inhibition as a test of attention, and impulsivity in a delayed reinforcement paradigm. Latent inhibition was present in control mice b...

Twenty-four children, from classes of emotionally disturbed children, were observed for behaviors of inattention, distractibility, and impulsivity. Each child was seen in either a distractive room or a distraction-free room while engaging in both a structured and an unstructured activity. The children seen in a distraction-free room displayed significantly less inattention (length of time off t...

This study advances research on mental health and entrepreneurship through the examination of Attention Deficit Hyperactivity Disorder (ADHD)-like symptoms, associated with hyperactivity/impulsivity inattention. We examine impact these symptoms at age 10 entrepreneurial performance as an adult. find that while ADHD-like in childhood may have a positive selection, they negatively survival perfor...

This study evaluated the effects of therapeutic horseback riding on social functioning in children with autism. We hypothesized that participants in the experimental condition (n = 19), compared to those on the wait-list control (n = 15), would demonstrate significant improvement in social functioning following a 12-weeks horseback riding intervention. Autistic children exposed to therapeutic h...

Timing deficits in schizophrenia have been noted in several behavioral studies. However, the involvement of mediating factors, such as inattention, has not been ruled out as contributing to these effects. Mismatch negativity (MMN), an electrophysiological measure, may provide a more direct index of stimulus processing ability in individuals with schizophrenia. The current study explored the rel...

The vast majority of studies that have examined the latent structure of attention deficit/hyperactivity disorder (ADHD) in children and adolescents have concluded that ADHD has a dimensional latent structure. In other words, ADHD symptomatology exists along a continuum and there is no natural boundary or qualitative distinction (i.e., taxon) separating youth with ADHD from those with subclinica...

We report a meta-analysis of up to 40 data sets that examined the personality dimensions in the Five-Factor Model (FFM) and the integrated Five-Factor Model (IFFM) in relation to ADHD symptom domains of inattention (IA) and hyperactivity/impulsivity (HI). The IFFM incorporated the dimensions of other personality models (in particular, those of Eysenck, Tellegen, and Cloninger, as well as the FF...

Although, ordinarily, upright objects are readily recognized by observers who are tilted, it is hypothesized that this is achieved by a process of correction. The first stage of that process is held to be a description of the object in relation to the biologically more primitive system of retinal coordinates. In order to test this hypothesis, tilted subjects were required to view figures under ...

The objective of this study were to highlight a new postoperative complication after surgery for retinal detachment. We report the case of a 50-year old patient with pseudotumoral scleral reaction to eyelashes and to MERSUTURE* filament occurred several months after surgery for retinal detachment. Eyelashes were accidentally retained due to surgeon’s inattention. The result was confirmed by ana...
