心理意象研究经受住了对这一现象的怀疑和固有的方法限制。在这里，我们回顾了最近的行为、脑成像和临床研究，这些研究重塑了我们对心理意象的理解。研究支持这样一种说法，即视觉心理意象是一种描述性的内部表征，其功能类似于一种弱的感知形式。脑成像工作已经证明，早在初级视觉皮层（V1），心理和感知图像的神经表征就彼此相似。V1的活动模式通过一组共同的低级描述性视觉特征来编码心理图像和感知图像。最近的转化和临床研究揭示了意象在许多精神障碍中发挥的关键作用，并建议临床医生如何在治疗中利用意象。最近的研究表明，视觉心理意象的功能似乎是一种弱的感知形式。有证据表明，视觉意象和视觉工作记忆之间存在重叠——那些具有强烈意象的人倾向于利用它来进行记忆。脑成像工作表明，早在V1阶段，感知刺激和心理图像的表征就彼此相似。意象在许多精神障碍中起着关键作用，临床医生可以利用意象来治疗这些障碍。
Mental imagery research has weathered both disbelief of the phenomenon and inherent methodological limitations. Here we review recent behavioral, brain imaging, and clinical research that has reshaped our understanding of mental imagery. Research supports the claim that visual mental imagery is a depictive internal representation that functions like a weak form of perception. Brain imaging work has demonstrated that neural representations of mental and perceptual images resemble one another as early as the primary visual cortex (V1). Activity patterns in V1 encode mental images and perceptual images via a common set of low-level depictive visual features. Recent translational and clinical research reveals the pivotal role that imagery plays in many mental disorders and suggests how clinicians can utilize imagery in treatment. Recent research suggests that visual mental imagery functions as if it were a weak form of perception. Evidence suggests overlap between visual imagery and visual working memory – those with strong imagery tend to utilize it for mnemonic performance. Brain imaging work suggests that representations of perceived stimuli and mental images resemble one another as early as V1. Imagery plays a pivotal role in many mental disorders and clinicians can utilize imagery to treat such disorders.
