“…There were a number of empirical reports documenting cognitive deficits among persons with schizophrenia, particularly in regard to deficits in abstraction, conceptualization, or a tendency toward overgeneralization (e.g., Bolles and Goldstein 1938 ; Cameron 1939b ; Fey 1951 ; Payne et al 1959 ; Rawlings 1921 ; Vigotsky 1934 ). With some exceptions (e.g., Babcock 1933 ; e.g., Rawlings 1921 ; Wittman 1937 ), the latter tended to be focused on a purely psychological level of description of the structure of schizophrenic thinking, i.e., with limited presumption or reference to neuropathologic mechanisms (see reviews by Lothrop ( 1961 ) and Wright ( 1975 )).…”

Application of a neuropsychological perspective to the study of schizophrenia has established a number of important facts about this disorder. Some of the key findings from the existing literature are that, while neurocognitive impairment is present in most, if not all, persons with schizophrenia, there is both substantial interpatient heterogeneity and remarkable within-patient stability of cognitive function over the long-term course of the illness. Such findings have contributed to the firm establishment of neurobiologic models of schizophrenia, and thereby help to reduce the social stigma that was sometimes associated with purely psychogenic models popular during parts of the 20th century. Neuropsychological studies in recent decades have established the primacy of cognitive functions over psychopathologic symptoms as determinants of functional capacity and independence in everyday functioning. Although the cognitive benefits of both conventional and even second generation antipsychotic medications appear marginal at best, recognition of the primacy of cognitive deficits as determinants of functional disability in schizophrenia has catalyzed recent efforts to develop targeted treatments for the cognitive deficits of this disorder. Despite these accomplishments, however, some issues remain to be resolved. Efforts to firmly establish the specific neurocognitive/neuropathologic systems responsible for schizophrenia remain elusive, as do efforts to definitively demonstrate the specific cognitive deficits underlying specific forms of functional impairment. Further progress may be fostered by recent initiatives to integrate neuropsychological studies with experimental neuroscience, perhaps leading to measures of deficits in cognitive processes more clearly associated with specific, identifiable brain systems.

“…There is a plethora of evidence in the literature which demonstrates that schizophrenics consistently evince decrements in performance in tasks requiring conceptual abilities (Buss & Lang, 1965;Craig, 197 Ib;Lothrop, 1961;Payne, 1961). Of theoretical importance is the question of whether schizophrenics have lost the ability to use abstraction (Goldstein, 1946) or whether they are prevented from abstracting because of interfering processes (Cameron, 1939).…”

“…The results have demonstrated poorer performance by schizophrenics, as compared to normals, which generally has led to the conclusion that the schizophrenic is deficient in abstracting capacity. However, in a recent review of the area, Lothrop (1961) raises the question as to whether there is an impairment of abstracting ability per se. Lothrop (1961) suggests that conceptual (abstracting) ability "... merely appears impaired because of some other deficit-producing factors involved in the performance" (p. 121).…”

Lothrop (1961) suggests that conceptual (abstracting) ability "... merely appears impaired because of some other deficit-producing factors involved in the performance" (p. 121). While not designed to identify the deficit producing factors explicitly, the present study attempts to demonstrate that chronic schizophrenics are capable of improving their performance in an abstraction task when task stimuli and instructions are made more complete.…”
