According to Fishbein’s Attitude Theory, an individual’s behavior is determined by his/her attitude towards it (Fishbein & Ajzen 1975). Moreover according to Social Identity Theory individuals form positive self-concepts by belonging to certain groups e.g., family or culture (Tajfel & Turner 1986). During the interviews we can see that many participants were open minded when it came down to forming relationships with people from other ethnic backgrounds; they accepted differences without any hesitation as they saw similarities rather than perceiving people based on preconceived notions related to race or religion (Dovidio et al 2000). For instance one participant explained: “At first I wasn’t sure if my parents would approve but once I talked them through it was fine…I didn’t care whether she was Asian or Scottish” indicating his openness towards race despite having worries about what others might think which demonstrates attitude theory in action as well as self concept theory being formed through identification with others who had similar experiences or shared understanding regardless of background . This highlights that although there may be initial hesitancy because of external pressures such as parental approval most people tend to accept those from diverse backgrounds if there appears similarities between them thus validating Social Identity Theory (Tajfel & Turner 1986).

Another relevant principle used throughout this film was Cultural Relativism which suggests that moral values vary across cultures leading individuals within a society ascribe different meanings depending on their beliefs and customs (Horton 1976). We could observe some examples during one particular scene when one couple compared their respective approaches towards child rearing while they discussed if parenting techniques were universal across cultures highlighting relativism at play since each partner believed different methods worked better for themselves due this being dependent on how each culture viewed acceptable parenting practices(Kakar 2007). Additionally during another segment two women described how they struggled initially after marrying someone outside their faith; here we could see Cultural Relativism influencing their conversations too since both women had conflicting perspectives regarding religious beliefs yet still managed to maintain relations underlining the importance of understanding different points of views rather than imposing own principles unto others hence confirming Horton’s view point(Horton 1976) .

Additionally Operant Conditioning plays an important role in developing our interpersonal relationships where rewards and punishments directly affect our behaviour influencing us positively or negatively(Skinner 1948) Similarly during this documentary we can find evidence suggesting reinforcement led several participants develop stronger bonds either due rewards received for loving acts performed ;for example one interviewee mentioned how he felt thankful whenever her wife cooked meals for him explaining how important gestures like these made him appreciate her more even though previously he found himself taking her kindnesses for granted demonstrating impact rewards have over human behaviour(Chiarello et al 1982 ). Furthermore another participant revealed she enjoyed travelling together with her husband indicating reward based activities lead couples connect better therefore strengthening ties between them further demonstrating explanation proposed Skinner’s theory(Skinner 1948).

In conclusion psychological theories provide numerous insights into why humans behave differently across various situations ranging from parent-child interaction , marital dynamics etc..This video highlighted various phenomenon such as attitude formation , self concept development ,cultural relativism ,rewards based conditioning etc ..which shaped behaviours exhibited by participants testifying deptheth potential psychology holds when trying unravel mysteries behind human actions making psychlogical insight invaluable tool today’s world.
