Growing up, Francisco, who struggles with schizophrenia, was not reinforced for paying attention to social cues. Over time, he gradually stopped attending to such cues and instead focused on irrelevant cues, which contributed to his bizarre responses in conversation. He was given more attention for his bizarre responses, which then reinforced more and more bizarre responses. This best demonstrates:
a. Operant conditioning
b. Modeling
c. Classical conditioning
d. Misinterpretation
