A new dichotic listening test (fused rhymed words) was used to monitor changes in perceptual asymmetry (PA) in patients recovering from acute psychotic episodes; some were also given a dichotic nonsense syllables test, a dichotic tone test, and a single visual field dot localisation test. Contrary to expectation, PA on the word test decreased with recovery, while asymmetry on the tone and dot tests did not change; results cut across diagnosis, could not be related to medication, and were independent of changes in overall performance. More specific hypotheses are needed than those of generalised single hemisphere dysfunction in major psychiatric illness, but existing models and concepts are inadequate to explain the findings.
一项新的双耳分听测试（融合押韵词）被用于监测急性精神病发作后康复患者的感知不对称性（PA）变化；部分患者还接受了双耳无意义音节测试、双耳音调测试和单视野点定位测试。与预期相反，单词测试中的PA随着康复而降低，而音调测试和点测试中的不对称性并未改变；结果不受诊断影响，与药物无关，且与整体表现的变化无关。除了关于主要精神疾病中广义单半球功能障碍的假设外，还需要更具体的假设，但现有的模型和概念不足以解释这些发现。
