OBJECTIVE The authors tested whether decisions about incongruencies in the representation and processing of semantic knowledge, thought to be related to cognitive control, are selectively impaired in schizophrenia. METHOD Twenty-four patients with schizophrenia and 24 healthy comparison subjects determined the relative size of paired stimuli as they are in the real world. Stimuli were words or images. Real-world "distance" (size difference between stimuli) was manipulated within pairs, as was…

False memory and schizophrenia: evidence for gist memory impairment
TLDR
When asked to consciously retrieve word lists, individuals with schizophrenia showed impairment not only in item-specific memory but also in gist memory, consistent with the storage deficit view of semantic memory in schizophrenia.
Thinking about semantic concepts in schizophrenia: The more familiar the less deviation
Category content and structure in schizophrenia: an evaluation using the instantiation principle.
TLDR
The authors suggest that the content and organization of categories in patients with schizophrenia is similar to that in healthy control participants.
Perception of emotion-related conflict in human communications: What are the effects of schizophrenia?
Genetics and Function of Neocortical GABAergic Interneurons in Neurodevelopmental Disorders
TLDR
The characteristics that underlie the great diversity of cortical GABAergic interneurons are summarized and how the multiple roles of these cells in developing and mature circuits might contribute to the aforementioned disorders are explored.

The "benefits" of distractibility: mechanisms underlying increased Stroop effects in schizophrenia.
TLDR
The findings confirmed several of the predictions and were consistent with the hypothesis that abnormal Stroop performance in schizophrenia reflects a failure to adequately attend to the task-appropriate stimulus dimension (color).
Semantic memory is impaired in schizophrenia
Role of left inferior prefrontal cortex in retrieval of semantic knowledge: a reevaluation.
TLDR
The findings suggest that it is selection, not retrieval, of semantic knowledge that drives activity in the left IFG, and counters the argument that the effects of selection can be attributed solely to variations in degree of semantic retrieval.
Rostral anterior cingulate cortex dysfunction during error processing in schizophrenia.
TLDR
There may be a disturbed affective or motivational response to the commission of errors in schizophrenia, in light of the role of the rostral ACC and other limbic structures in mediating affective and motivational behaviour.

In this experiment, Ss were visually presented with the names of two animals and were required to throw a switch under the name of the larger animal. Although error rates were relatively low (4.5%),…
A standardized set of 260 pictures: norms for name agreement, image agreement, familiarity, and visual complexity.
TLDR
A standardized set of 260 pictures, selected to provide exemplars from several widely studied semantic categories, are presented for use in experiments investigating differences and similarities in the processing of pictures and words.
