Recent studies posit that deficits in emotion regulation may lead to increased negative emotional experience in schizophrenia. While individuals with schizophrenia evidence a number of abnormalities in emotion regulation, it is unclear whether these deficits are discrete or related; furthermore, the mechanisms underlying these deficits are not…

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…

The behavioural phenotype of velocardiofacial syndrome (VCFS), one of the most common human multiple anomaly syndromes, includes developmental disabilities, frequently including intellectual disability (ID) and high risk of diagnosis of psychotic disorders including schizophrenia. VCFS may offer a model of the relationship between ID and risk of…

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…

The prefrontal cortex of the primate frontal lobes provides the capacity for judgment which can constantly adapt behavior in order to optimize its outcome. Adjudicating between long-term memory programs and prepotent responses, this capacity reviews all incoming information and provides an interpretation dependent on the events that have just…

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…

An attempt was made to uncover dysfunctions in any of the mechanisms in selective attention, as well as any unusual allocation policy, which possibly exist in schizophrenia. (Author/RK)

Tests three proposed attentional mechanisms as possible behavioral strategies by which schizophrenics could prevent relevant information from registering and considers whether stimulation coming through the visual or the auditory channels is differentially susceptible to motivated attempts to disattend to relevant information.

Examines certain theoretical explanations of attention disorders in chronic nonparanoid schizophrenics that have been presented by several authors in the context of interference theory. Attempts to clarify divergencies in their theoretical assumptions by replicating and extending their research findings. (Author/RK)
