  Stirling (2006) investigated the performance of people with SZ and a control group using a stroop test. They found SZ patients took over twice as long to read the ink colour than the controls. Research support that the cognitive process (central control) of people with SZ are impaired
• weakness

  There is a problem with cause and effect – do cognitive deficits causes SZ or does SZ cause these cognitive deficits?We can not identify cause and effect which makes understanding the causes of SZ harder
• weakness

  The cognitive model is reductionist as it does not consider biological factors such as neurotransmitters and genetics. Suggests the cognitive approach is over simplistic as an explanation for SZ and reduces the validity of the explanation.
