There is a need to study prospective memory (PM) and its relationship with aspects of frontal lobe functioning in schizophrenia and bipolar disorder. The study aims to investigate event-based (EB) and time-based (TB) PM functioning in the two groups, and its association with working memory, planning, and attention. A word categorisation task was…

Schizophrenia is a devastating mental disorder that affects thought, language and communication. Considering the language disorders, the aim of this study is to examine the average sentence length of patients with Schizophrenia and compare the results with a control group by using four different language tests. Fifty patients with schizophrenia…

Continued human and animal research has strengthened evidence for aberrant excitatory-inhibitory neural processes underlying autism and schizophrenia spectrum disorder psychopathology, particularly psychosocial functioning, in clinical and nonclinical populations. We investigated the extent to which autistic traits and schizotypal dimensions were…

The present study compared 21 high functioning individuals with autism, 21 individuals with schizophrenia and 21 healthy individuals in self-reported features of autism, as measured by the Autism-spectrum Quotient (AQ). The individuals with autism reported impairment on all AQ subscales, compared to the neurotypical group. The schizophrenia group…

Background: This study investigates the role of IQ, autistic traits and challenging behaviours in affecting adult outcomes among adolescents who receive special educational assistance. Methods: A total of 58 participants were recruited from an ongoing longitudinal study. All received assessments of IQ, behavioural patterns (using the Childhood…

Objective: Several studies have documented a profile of elevated scores on the Attention Problems, Aggressive Behavior and Anxious/Depressed scales of the Child Behavior Checklist (CBCL) in youth with bipolar disorder. The sum of these scales, referred to as the CBCL Juvenile Bipolar Disorder (JBD) phenotype, has modest diagnostic utility, and…

Background: Individual differences in specific components of attention contribute to behavioral reactivity and regulation. Children with the temperament of behavioral inhibition (BI) provide a good context for considering the manner in which certain components of attention shape behavior. Infants and children characterized as behaviorally…

Objective: Previous cross-sectional studies in adolescents with early-onset schizophrenia (EOS; onset of psychotic symptoms by 18 years of age) have reported patterns of generalized neurocognitive deficits as compared to healthy comparison subjects (HCSs). Here, the authors examined the longitudinal stability of neuropsychological deficits in…

Results of three experiments suggest that groups of schizophrenic, younger normal, and older normal children used a serial information-processing strategy while performing on a partial report version of a span of apprehension task. Impairment of schizophrenic children on the partial report versions seemed to reflect inefficiencies in the…

The construct validity of neuropsychological tests in patients with schizophrenia was studied with 39 patients who were evaluated with a battery of six tests assessing attention, memory, and abstract reasoning abilities. Results support the construct validity of the neuropsychological tests in patients with schizophrenia. (SLD)

Cognitive and attentional deficits were assessed in school-age children with either a schizophrenic, an affectively disordered, or a normal parent (N=675). Children whose parents met the more stringent criteria for schizophrenia performed somewhat more deviantly than children whose parents met more general criteria. (Author)

While neuropsychology relates the neural structures damaged in traumatic brain injury with their cognitive functions in daily life, this report reviews evidence that elementary operations of cognition as defined by cognitive studies are the level at which the brain localizes its computations. Orienting of visual attention is used as a model task.…
