The Bystander Effect: Theory and Examples

The bystander effect, also known as the Genovese effect, suggests that the likelihood of someone helping in a situation is inversely related to the number of people present. This means that a person is more likely to help if there are fewer witnesses. The term Genovese effect comes from the case of Kitty Genovese, who was sexually assaulted and killed in front of a large apartment building. Despite 38 neighbors hearing her screams, no one called the police. However, the facts of this story have been largely shown to be inaccurate.

Bystanders are less likely to help if there are many other people present, if the perpetrator is present, if the costs of intervention are physical, and if the situation is perceived as dangerous. On the other hand, bystanders are more likely to help if they are male and if they know the person in need of help. Overall, the bystander effect has been shown to be a valid concept, as demonstrated by research studies.

Parapraxis: A Freudian Slip of the Tongue

A parapraxis, commonly known as a ‘slip of the tongue’, is a Freudian concept that suggests that these slips reveal important information about the repressed content of the unconscious mind. According to Freud, these mistakes are not accidental but rather a manifestation of the unconscious mind’s desires and thoughts. For instance, a person may accidentally call their boss by their partner’s name, revealing an underlying attraction of resentment towards their boss. Freud believed that these parapraxes could provide valuable insights into a person’s psyche and help uncover repressed memories of emotions. Therefore, he considered them an essential tool in psychoanalysis. Today, parapraxes are still studied and analyzed by psychologists and therapists to gain a better understanding of their patients’ unconscious thoughts and feelings.

The Nuremberg Code and its Significance in Medical Ethics

The Nuremberg Code is a set of ethical guidelines that resulted from the trial of German physicians accused of war crimes and crimes against humanity in 1946. The physicians were charged with conducting medical experiments on concentration camp prisoners without their consent. This led to the creation of the Nuremberg Code, which was the first international document to advocate for voluntary participation and informed consent in medical experimentation.

The Nuremberg Code has since become a cornerstone of medical ethics and has been adopted by many countries and organizations around the world. It emphasizes the importance of protecting the rights and welfare of human subjects in medical research and requires that any experimentation be conducted with the voluntary and informed consent of the participants.

The significance of the Nuremberg Code cannot be overstated, as it has helped to shape the way medical research is conducted and has led to greater awareness and respect for the rights of human subjects. It serves as a reminder of the atrocities committed during the Holocaust and the importance of ethical considerations in medical research.

The four principles serve as a framework for ethical discussions, rather than being an ethical theory themselves. They provide guidelines that can be used regardless of the ethical theory that the participants may hold.

Ethical theory and principles are important in medical ethics. There are three key ethical theories that have dominated medical ethics: utilitarianism, deontological, and virtue-based. Utilitarianism is based on the greatest good for the greatest number and is a consequentialist theory. Deontological ethics emphasize moral duties and rules, rather than consequences. Virtue ethics is based on the ethical characteristics of a person and is associated with the concept of a good, happy, flourishing life.

More recent frameworks have attempted to reconcile different theories and values. The ‘four principles’ of ‘principlism’ approach, developed in the United States, is based on four common, basic prima facie moral commitments: autonomy, beneficence, non-maleficence, and justice. Autonomy refers to a patient’s right to make their own decisions, beneficence refers to the expectation that a doctor will act in a way that will be helpful to the patient, non-maleficence refers to the fact that doctors should avoid harming their patients, and justice refers to the expectation that all people should be treated fairly and equally.

If you are familiar with the ‘phonological Loop’ component of the working memory, you may be able to deduce the meaning of the ‘phonological similarity effect’. This effect describes the difficulty in remembering words that sound alike. Additionally, the ‘word-length effect’ and ‘articulatory suppression’ are two other phenomena that involve the working memory.

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Sensory memory is the capacity for briefly retaining the large amounts of information that people encounter daily. It includes echoic memory (gathered through auditory stimuli), iconic memory (gathered through sight), and haptic memory (acquired through touch).

Short-term memory is the ability to keep a small amount of information available for a short period of time. Atkinson and Shiffrin’s multistore model (1968) suggests the existence of a short-term storehouse with limited capacity. Baddeley and Hitch (1974) further developed the concept of short-term memory, which eventually became known as Baddeley’s multi-storehouse model (2000). This model includes the central executive, visuospatial sketchpad, phonological buffer/loop, and episodic buffer.

Long-term memory includes declarative (of explicit) memories, which can be consciously retrieved, and nondeclarative (of implicit) memories, which cannot. Declarative memory includes episodic memory (stores personal experiences) and semantic memory (stores information about facts and concepts). Non-declarative memory includes procedural memory (recalls motor and executive skills), associative memory (storage and retrieval of information through association with other information), and non-associative memory (refers to newly learned behavior through repeated exposure to an isolated stimulus).

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.

The Thematic Apperception Test is a personality test that falls under the category of projective tests, which involve describing rather than measuring a specific aspect.

Personality Testing

There are two main types of personality tests: projective and objective. Projective tests aim to assess unconscious material by presenting subjects with ambiguous pictures of phrases to elicit an unconscious response. Examples of projective tests include the Rorschach Inkblot, Thematic Apperception Test, Draw-A-Person test, and sentence completion tests. On the other hand, objective tests have structured and clear questions and aims. Examples of objective tests include the Minnesota Multiphasic Personality Inventory, Sixteen Personality Factor Questionnaire (16PF), NEO Personality Inventory, and Eysenck Personality Test (EPQ).

Goffman’s work focused extensively on stigma, while Cerletti is known for his contributions to the development of electroconvulsive therapy (ECT), and Moniz is associated with the development of frontal lobotomy.

Ribot’s Law and Jost’s Law: Understanding Memory Consolidation and Forgetting

Ribot’s Law, also known as the law of retrograde amnesia, suggests that recent memories are more likely to be lost than older ones. This implies that memories need time to consolidate and become more resistant to forgetting. Ribot observed that people who experience traumatic events often lose memories leading up to the event, but older memories are preserved. This pattern is also observed in patients with Alzheimer’s disease, where the saying goes, you lose first what you learn last.

Jost’s Law of forgetting complements Ribot’s Law by stating that if two memories are of the same strength but different ages, the older memory will decay more slowly than the younger one. Together, these laws suggest that memory consolidation is a gradual process that takes time, and once memories are consolidated, they become more resistant to forgetting. Understanding these laws can help us better understand how memories are formed, retained, and lost over time.

Freud’s Structural Theory: Understanding the Three Areas of the Mind

According to Freud’s structural model, the human mind is divided into three distinct areas: the Id, the Ego, and the Superego. The Id is the part of the mind that contains instinctive drives and operates on the ‘pleasure principle’. It functions without a sense of time and is governed by ‘primary process thinking’. The Ego, on the other hand, attempts to modify the drives from the Id with external reality. It operates on the ‘reality principle’ and has conscious, preconscious, and unconscious aspects. It is also home to the defense mechanisms. Finally, the Superego acts as a critical agency, constantly observing a person’s behavior. Freud believed that it developed from the internalized values of a child’s main caregivers. The Superego contains the ‘ego ideal’, which represents ideal attitudes and behavior. It is often referred to as the conscience. Understanding these three areas of the mind is crucial to understanding Freud’s structural theory.
