Fascinating Case Studies for A-Level Psychology

Human behaviour is a vast and intricate tapestry, woven from countless psychological threads we are still trying to unwind through scientific study. To truly understand the complexities of why we think, feel, and act the way we do, psychologists often turn to case studies.

These detailed examinations of individuals or groups provide profound insights into various psychological phenomena. In this blog post, we will explore some of the most fascinating case studies covered in A-level Psychology, shedding light on the diverse aspects of human behaviour.

The Story of Phineas Gage: A Journey into the Brain

One of the most iconic case studies in psychology is that of Phineas Gage, a railroad construction foreman who survived a traumatic brain injury in 1848. Gage's story is not only remarkable due to his survival but also because of the profound changes in his personality and behaviour that followed the accident.

Gage was working with explosives when a tamping iron was accidentally driven through his skull, entering his left cheek and exiting through the top of his head. Astonishingly, Gage remained conscious and was able to walk and talk immediately after the incident. However, the injury severely damaged his frontal lobes, particularly the prefrontal cortex, which is associated with decision-making, social behaviour, and personality.

Before the accident, Gage was described as a hardworking, responsible, and sociable individual. After the injury, his behaviour changed drastically. He became impulsive, irritable, and prone to inappropriate social behaviour. This dramatic transformation provided early evidence of the role of the frontal lobes in personality and self-control, illustrating how brain injuries can alter human behaviour.

Little Albert: Unveiling the Mechanics of Fear

The case of Little Albert is another cornerstone in the study of human behaviour, particularly in understanding how emotions can be conditioned. Conducted by John B. Watson and Rosalie Rayner in 1920, this controversial experiment aimed to demonstrate that fear could be learned through classical conditioning.

Little Albert, an 11-month-old baby, was exposed to various stimuli, including a white rat, a rabbit, and a dog, to which he initially showed no fear. Watson and Rayner then paired the presence of the white rat with a loud, frightening noise. After several pairings, Albert began to exhibit fear responses not only to the white rat but also to other similar objects, such as a fur coat and a Santa Claus mask.

This experiment illustrated the principles of classical conditioning and provided insights into the development of phobias. It showed that emotional responses could be conditioned and generalised to other stimuli, laying the groundwork for further research in behaviourism and therapeutic techniques for treating phobias.

Genie: The Wild Child and the Critical Period Hypothesis

The case of Genie, a girl discovered in 1970 at the age of 13, presents a tragic yet enlightening exploration of language acquisition and development. Genie had been severely neglected and isolated by her abusive father, spending most of her early life confined to a small room with minimal human interaction.

When Genie was found, she had little to no language skills, and her case became a focal point for studying the critical period hypothesis—the idea that there is a specific window in early childhood during which language acquisition occurs most naturally and effectively.

Despite intensive rehabilitation efforts, Genie never fully acquired normal language abilities, although she did make some progress. Her case provided compelling evidence supporting the critical period hypothesis and highlighted the profound impact of early environmental deprivation on cognitive and social development.

The Stanford Prison Experiment: Unmasking the Darkness Within

Conducted by Philip Zimbardo in 1971, the Stanford Prison Experiment remains one of the most infamous and ethically debated studies in psychology. Zimbardo sought to investigate the psychological effects of perceived power and authority by simulating a prison environment with college students assigned to roles as either guards or prisoners.

The experiment quickly spiralled out of control as the ‘guards’ adopted authoritarian behaviours, subjecting the ‘prisoners’ to psychological abuse and dehumanising treatment. The ‘prisoners,’ in turn, became increasingly passive and distressed. Originally planned to last two weeks, the experiment was terminated after just six days due to the extreme and disturbing behaviour exhibited by the participants.

This study revealed the power of situational factors and social roles in shaping behaviour, demonstrating how ordinary individuals can engage in harmful actions when placed in certain contexts. It raised important ethical questions about the treatment of participants in psychological research and the potential for abuse of power.

HM: Unlocking the Secrets of Memory

The case of Henry Molaison, known as HM, has been pivotal in advancing our understanding of memory. HM underwent brain surgery in 1953 to alleviate severe epilepsy, during which large portions of his medial temporal lobes, including the hippocampus, were removed. While the surgery successfully reduced his seizures, it also left him with profound anterograde amnesia, rendering him unable to form new long-term memories.

HM could remember events from before the surgery but could not create new memories, effectively living in a perpetual present. Despite this, his short-term memory and procedural memory (such as learning new skills) remained intact. His case provided critical insights into the different types of memory and the specific brain regions involved in memory formation and retrieval.

Researchers studying HM's condition learned that the hippocampus is essential for the consolidation of new explicit memories but not for procedural memory. HM's case underscored the complexity of memory systems and has informed the development of treatments and interventions for memory disorders.

Kitty Genovese: A Catalyst for Understanding Bystander Behaviour

The tragic murder of Kitty Genovese in 1964 in New York City became a catalyst for research into bystander behaviour and the diffusion of responsibility. Genovese was attacked and murdered outside her apartment, with reports indicating that numerous neighbours heard her cries for help but did not intervene or call the police.

This incident spurred psychologists John Darley and Bibb Latané to investigate the phenomenon of the bystander effect. Their experiments demonstrated that individuals are less likely to help a victim when others are present, due to a diffusion of responsibility and social influence. The more witnesses there are, the less personal responsibility each person feels to act.

The Genovese case and subsequent research have had a lasting impact on our understanding of social psychology, highlighting the factors that influence helping behaviour and the importance of fostering a sense of personal responsibility in emergency situations.

David Reimer: The Boy Who Was Raised as a Girl

David Reimer's story is a poignant and controversial case study in the field of gender identity and the nature versus nurture debate. Born biologically male in 1965, David suffered a botched circumcision that led his parents, under the guidance of psychologist John Money, to raise him as a girl named Brenda.

Money believed that gender identity was primarily shaped by socialisation, and David's case was intended to prove this theory. However, despite being raised as a girl, David consistently exhibited male behaviours and experienced significant psychological distress. At the age of 14, he learned the truth about his birth and subsequently transitioned back to living as a male.

David Reimer's case challenged the notion that gender identity is solely a product of upbringing and highlighted the complex interplay between biological and environmental factors. It underscored the importance of considering individual experiences and the potential harm of imposing rigid gender roles.
