Hand-dynamometer induced muscle tension was manipulated in the context of an experimental paradigm that included tests of discrimination and generalization with rigorously defined schizophrenic and affective patients, as well as schizotypic and normal controls (total N = 44). The experiment was designed to test predictions that derive from Broen and Storms' (1967) learning/motivational analysis of schizophrenic performance deficits. The results failed to support the theoretical predictions, but did reveal that the ability to maintain induced muscle tension within prescribed limits discriminated reliably between the groups (p less than or equal to .03) and that this discriminability increased with increasing tension demands (p less than or equal to .001). The data are discussed in terms of possible relations to basic sensory/motor (i.e., neuromuscular and/or proprioceptive) mechanisms as well as to more central psychological (i.e., attentional/cognitive) mechanisms, and directions for future research are outlined.
在一个实验范式中，通过握力计来操纵肌肉张力，该范式包括对严格界定的精神分裂症患者、情感障碍患者、分裂型人格障碍患者和正常对照组进行辨别和泛化测试（样本总数N = 44）。该实验旨在检验从布罗恩和斯托姆斯（1967年）对精神分裂症患者表现缺陷的学习/动机分析中得出的预测。结果未能支持理论预测，但确实表明，在规定限度内维持诱导肌肉张力的能力在不同组之间具有可靠的区分度（p≤0.03），并且这种区分能力随着张力要求的增加而增强（p≤0.001）。本文从与基本感觉/运动（即神经肌肉和/或本体感觉）机制以及更高级的心理（即注意力/认知）机制的可能关系方面对数据进行了讨论，并概述了未来研究的方向。
