Clinical psychologist Dawn Hughes acknowledged during her testimony that Johnny Depp experienced physical violence and verbal trauma during his relationship with Amber Heard.

"I can testify that he had physical acts of violence perpetrated on him as well as psychological aggressive acts perpetrated upon him," Hughes said while on the stand.

Some of that verbal trauma was displayed on Wednesday, when multiple audio recordings of Depp and Heard were played, showing even more evidence of volatility in the relationship.

"I need to know what we do different if I have a problem. You need to tell me how to tell you different if I'm hurting you ... sometimes you're going to make me mad. I'm a human," Heard can be heard saying.

Depp then replies, "Well, the same thing goes for me then. You're going to have to allow me to get mad."

"Yes, exactly," Heard replies.

The couple then talks about how Heard begins to yell when they fight, which she can be heard saying only happens when their argument reaches "hour 11."

In another audio, Depp can be heard saying he doesn't want to leave Heard, but he doesn't want the toxicity of their relationship to continue.

"I love you and I do not want to leave you ... I just want peace," Depp says in a muffled audio.

Clinical psychologist Dawn Hughes defended her conclusion that Heard has post-traumatic stress disorder after Depp's legal team attempted to undermine her examinations.

In her testimony, Hughes explained the two clinical tests she administered while examining Heard: the DSM-5 and CAPS-5 testing. The first, from the Diagnostic and Statistical Manual of Mental Disorders, looks at a patients self-reported answers to diagnose a variety of potential disorders.

The second, the Clinician-Administered PTSD Scale, derives from the DSM-5 testing to make an accurate diagnosis.

Hughes testified that she administered both tests over years and attempted to discern what symptoms Heard expressed as a result of her relationship with Depp and which symptoms were from her childhood experience with abuse.

"So there are multiple measures that are consistent across time that she meets the criteria for PTSD," Hughes said.

Hughes spent roughly 29 hours with Heard, not administering treatment but offering a forensic examination based on interviews, prior medical records, and prior examinations by other psychologists.

She contradicted prior testimony made by Shannon Curry, an expert witness for Depp, who diagnosed Heard with borderline personality disorder and histrionic personality disorder. Curry, who spent 12 hours with Heard, told the court she had "exaggerated" symptoms of PTSD.

Hughes testified Wednesday that the results of her tests were "valid and reportable, there were no signs of exaggeration."

Johnny Depp's attorneys began Wednesday with their cross-examination of Amber Heard’s first witness, Dawn Hughes, a clinical psychologist.

Hughes told the court Tuesday that she had diagnosed Heard with post-traumatic stress disorder as a result of what she described as intimate partner violence she experienced during her relationship with Depp. 

Psychologist Shannon Curry, an expert witness presented by Depp’s legal team, previously rejected the idea that Heard had post-traumatic stress disorder. Curry diagnosed Heard with borderline personality disorder and histrionic personality disorder, which Hughes disagreed with. 

Depp's team pushed Hughes on her descriptions of victims of intimate partner violence Tuesday using primarily she and her pronouns and descriptions of perpetrators as primarily male. They also pushed Hughes on being paid to testify.

Hughes rejected characterizations that she makes her income primarily off testifying in court cases, saying many of her cases never go to trial. She also said that she did in fact work with many male clients of sexual abuse or intimate partner violence.

Johnny Depp and Amber Heard’s relationship began more than a decade ago, and eventually devolved into what appears to have been a toxic marriage.

The couple split in 2016, but have continued to battle in court over an op-ed Heard wrote for The Washington Post in 2018, in which she described surviving domestic violence -- without mentioning Depp by name.

The trial, which is being held in Fairfax County, Virginia, is expected to take weeks. Here’s a timeline of Depp and Heard’s relationship leading up to the court case.

Heard’s attorneys argued for a motion to dismiss Tuesday on the basis that Depp’s attorneys failed to meet their burden of proof, calling it undisputed that Heard was physically and verbally abused. They also argued that Depp’s attorneys have questioned the headline for the essay’s online version. But the headline was written by The Washington Post, not Heard, according to one of Heard’s attorneys. 

Depp’s attorneys argued that Heard cosigned the headline as her own when she tweeted the article in December 2018, but his legal team has not submitted the tweet to the court as evidence.

Judge Penney Azcarate said Tuesday that it will be up to the jury to determine whether the weight of the evidence presented by Depp’s team has met the burden, dismissing those arguments.

But as for whether or not Heard’s tweet constituted an adoption of The Washington Post’s headline, Azcarate said she’d continue to take it under advisement.

“There seems to be an agreement that the tweet of Ms Heard is part of the plaintiff’s evidence, which is not in evidence at this point,” Azcarate said Tuesday. “So I can’t rule on that statement whether or not it is just a tweet or if it’s some sort of republication ... I don’t know because I haven’t seen it yet.”

A WebMD profile of a clinical psychologist was flooded with negative comments on Tuesday after she testified as the first defense witness for Amber Heard.

Dr. Dawn Hughes, who was called to the stand by Heard’s legal team, testified that she diagnosed Heard with post-traumatic stress disorder as a result of what she described as intimate partner violence experienced during her relationship with Depp.

As Hughes was on the stand, a WebMD physician profile with her name and practice information was hit with a barrage of negative reviews.

WebMD did not immediately respond to a request for comment Tuesday. The reviews appeared to be removed from the website after NBC News reached out to WebMD.

It’s unclear if Hughes created the profile herself. She did not immediately respond to NBC News’ request for comment regarding the page and its reviews.

In many of the reviews, commenters accused Hughes of being biased against men in cases of domestic abuse, calling her sexist and unprofessional.

“bad energy, vicious and hates men. ... this review was created by a woman,” one review read.
