- Schizophrenia research has predomi­nantly focused on nonsocial cognition (also referred to as neurocognition).
- Nonsocial cognition includes those commonly considered mental abilities, including speed of processing, verbal learning and memory, visuospatial learning and memory, working memory, attention/vigilance, and reasoning and problem solving.

Future Directions for Research on Cognition in Schizophrenia 

A set of symptoms of schizophrenia that affects the normal processes of the brain that helps day to day functioning

Cognitive Impairment

A type of information processing deficit that would negatively impact cognition from the very beginning

Perceptual Impairment

Interest in social cognition as it relates to schizophrenia is a more recent development, and research in this area has grown dramatically over the past 10-­15 years.

Social Cognition in Schizophrenia

Cognition is another area of functioning that is affected in schizophrenia leading to problems with attention, concentration and memory, and to declining educational performance.

The primary symptoms of schizophrenia are categorized into five main types: hallucinations, delusions, disorganized thinking, disorganized or abnormal motor behavior, and negative symptoms. When the disorder is active, individuals may struggle to differentiate between real and unreal experiences. The severity, duration, and frequency of these symptoms can vary, and severe psychotic symptoms often decrease with age.

Nonsocial and social cognition in schizophrenia: current evidence and future directions

(those abnormally present) Hallucinations, such as hearing voices or seeing things that do not exist, paranoia and exaggerated or distorted perceptions, beliefs and behaviors.

Positive Symptoms of Schizophrenia 

Confused and disordered thinking and speech, trouble with logical thinking and sometimes bizarre behavior or abnormal movements.

Disorganized Symptoms of Schizophrenia 

Cognitive Symptoms of Schizophrenia 

Negative symptoms involve significant reductions and absences of typical behaviors, emotions, or motivations (Green, 2001). These symptoms signify a loss of normal functions and include diminished emotional expression, avolition, alogia, asociality, and anhedonia.

Negative Symptoms of Schizophrenia

Prodromal symptoms in schizophrenia refer to the slight, early symptoms of psychosis. This could mean that the individual is going through odd communications, paranoia, and delusions.
