Which of the following is an example of a secondary cognitive symptom of schizophrenia?

The choice of processing speed deficits as an example of a secondary cognitive symptom of schizophrenia is accurate because secondary cognitive symptoms are typically seen as a result of the primary symptoms of the disorder, such as psychosis. In schizophrenia, cognitive functions can be impacted by factors such as medication side effects, the overall impact of the illness on daily functioning, and the social environment.

Processing speed deficits specifically reflect difficulties in the quick retrieval and application of information, which can arise from the primary symptoms or stressors associated with schizophrenia. These cognitive impairments are not directly caused by the core symptoms of schizophrenia itself, such as hallucinations or delusions, but are instead linked to the overall impact of the disorder on cognitive function.

In contrast, social neglect is more closely related to negative symptoms, which reflect an absence or reduction in normal emotional response or behavior. Affect instability pertains to emotional symptoms, showcasing a lack of stability in emotional expression. Visual hallucinations are a core positive symptom of schizophrenia, indicative of psychotic experiences that involve perceiving things that are not present. Thus, processing speed deficits illustrate a cognitive impairment that emerges as a secondary consequence of the condition's more primary aspects.
