Psychology Psychology was the study in the field of science of Human mental processes and behavior ; after space exploration and First Contact , it seems to have been expanded to include other humanoid s in fields such as space psychology and exopsychology . One who practiced in this field was known as a psychologist or counselor . After confronting Bu ' kaH in 2151 , Jonathan Archer later told that " " I think I might have made a tactical error dealing with the Klingon woman . I asked her for help . She could see that as a sign of weakness . " " In response , Tucker asked if Archer had " " been boning up on your Klingon psychology ? " " Archer then explained that " " we ' ve run into them three times , and every time they ' ve wanted to destroy us . I ' d love to figure out why . " " ( ) After Ensign was confined to his quarters for not firing his phaser quickly enough at the dikironium cloud creature on Argus X , Christine Chapel visited him , carrying a bowl of soup and a tape . Garrovick told her that he was not hungry , and instead wanted to know what was going on outside of his quarters . When Chapel told him that things were pretty chaotic , and that he was better off where he was , he began to go into a rant about how everything was his fault . In response , Chapel told him , " " You know , self - pity ' s a terrible first course . Why don ' t you try the soup instead ? " " He again insisted that he was not hungry , at which point told him , " " Doctor McCoy thought you might say something like that , " " then held up the tape she was carrying and told him " " this is his officially logged prescription for you . It has one word on it . Eat . Now if you don ' t follow his orders , Doctor McCoy could and possibly would have you hauled down to sickbay and fed intravenous ly , " " and then left . Upon returning to sickbay , she put the tape down . McCoy picked it up and read that it was " A Survey on Cygnian Respiratory Diseases " , and asked , " " I thought you took Garrovick some food . What were you doing with this ? " " Chapel responded , " " Applying psychology . " " ( ) During the early 2350s , Benjamin Sisko and some friends where enjoying some free time at The Launching Pad when they were confronted by and some other Vulcan cadet s , who " were doing research on illogical Human bonding rituals . " Sisko and his friend didn ' t take kindly to that , and they got into a debate , and offered to solve the situation and prove that Humans were the equal of Vulcans by challenging Solok to a wrestling match , in which Sisko was easily defeated . Afterward , Solok took every opportunity to remind Sisko of the match by pointing him out as he walked across the campus , and later by writing five psychology papers about the match . Even after graduation , Solok continued to write about the match , having written over a dozen papers on Vulcan / Human comparative profiles by the mid - 2370s , with each paper beginning with an analysis of their wrestling match . ( ) Deanna Troi first met Tam Elbrun at the University of Betazed when she was studying psychology there during the late 2350s . At the time he was her patient . ( ) After Troi had lost her empathic abilities in 2367 , she was told by Beverly Crusher that her condition was " no different than if one of us suddenly going blind . " Troi replied , " " Doctor , you don ' t have to tell me , I understand the psychology , " " to which Crusher responded , " " you may understand it , but you ' ve never had to live with it . " " Troi was later visited in her quarters by William T . Riker , who stated " " I don ' t have a psychology degree , but if you want to talk . . . " " as his way of helping her out . Later , when Jean - Luc Picard needed Troi ' s assistance with understanding the two - dimensional lifeform s the encountered , he told her " " if there is a psychology to these creatures , we must discover it , if there is an explanation to their behavior , we must know it . Even in your current condition , you are the most qualified person aboard this ship to assist . " " ( ) In 2368 , Aaron Conor told Deanna Troi , while describing his society , that " " my psychology tells me that I was born to lead . " " ( ) In 2369 , Jean - Luc Picard attended a physiognomy workshop , where Dr . Vassbinder gave an hour - long dissertation on the ionization effect on warp nacelle s before he realized that the topic was supposed to be psychology . ( ) The Delta Quadrant Think Tank solved problems by using what was described as " pure tactics , [ and ] psychology . " ( ) " In an alternate timeline , Reginald Barclay and Kathryn Janeway taught a class at Starfleet Academy about the Borg , where their cadet s would " learn about the assimilation process , the Borg hierarchy , and the psychology of the hive mind .
