The study of psychobiology attempts to explain behaviour in terms of physiological mechanisms. Previous research shows that female and male reactions differ with regards to emotional stimuli (Campbell et al., 2002 & Orozco & Ehlers, 1998, as cited in Hall, 2004). “Sex Differences in Functional Activation Patterns Revealed by Increased Emotion Processing Demands” (Hall, Witelson, Szechtman, & Nahmias, 2004) studied the effects that different emotional stimuli have on brain activation patterns (Hall et al.). The study was divided into two experiments, both of which compared and contrasted the results between two different groups of eight women and eight men (Hall et al.). In experiment one, patients performed three tasks: facial detection, identity matching and emotion matching (Hall et al.). In experiment two, a different group of eight women and eight men performed gender matching and emotion matching, with an additional auditory stimulus (Hall et al.). The results showed that sexual dimorphism was present in the reactions between women and men (Hall et al.). This essay proposes to examine the psychobiological aspect of the studies, to identify any interesting and relevant results, and to analyze its key elements and scientific rigor. Furthermore, it will explore possible future improvements to the study, as well as highlight possible applications of the results. This essay will prove that the research paper is both relevant and interesting to psychobiology.
Relevance to Psychobiology
As previously mentioned above, psychobiology studies psychological phenomena in terms of biological processes. Studies that are deemed to be psychobiological must consist of both psychology and biology. The study focused on the ar...

Physiological Psychology : The Biological Basis Of Behavior Essay

- Physiological psychology is the science that studies the biological basis of behavior. It is often referred to as biological psychology, biopsychology, or psychobiology. Physiological psychology is the original name for this field but there are other terms which are used like biological psychology, or behavioral neuroscience. This is just a field of psychology that connects behavior and mental processes to bodily processes, and to the functions and actions of the brain. The brain, in turn, affects behavior and the mind....   [tags: Psychology, Nervous system, Biology, Mind]

An Analysis of the Literary Mechanisms in Barbara Kingsolver's Flight Behaviour

- Knowledge is an accumulation of experiences, which are obtained either conventionally in a school setting or indiscriminately through life-experiences. Likewise, from these experiences conventional or otherwise, information is then transferred, acquired, and reappropriated. However, within this sequence of events knowledge is at risk of misinterpretation. In those circumstances it is the story, the most ancient form of communication, which is capable of making the unfamiliar appear obvious. Through her novel Flight Behaviour, Barbara Kingsolver acts as a teacher, surreptitiously conveying her own opinions on education and the process of learning through the development of her characters....   [tags: Flight Behaviour Essays]

Essay about Mechanisms of Sex in Escherichia coli

- The discovery of the gene transfer mechanisms could be attributed by the work of Lederberg and Tatum back in 1946. Using Escherichia coli(E.coli) as their model, they proposed the genetic materia of E.coli could be exhanged via sexual process. In order to prove their hypothesis, they mutated 2 wild type E.coli strains(K12) using X-ray or ultra-violet radiation to produce Y-10 and Y-24 mutant strains. The former was auxotrophic to threonine, leucine and thiamin whereas the latter failed to produce biotin, phenylalanine and cystine[1]....   [tags: Gene Transfer Mechanisms]

Alternative Dispute Resolution Mechanisms Essay

- The resolution of disputes through alternative dispute resolution mechanisms has gained momentum over recent decades. It has increasingly occupied space in the academic literature as the “new” method to achieve “justice” for disputing parties. It is important to note that a variety of definitions of “justice” can be relied upon. However, in many cases, justice will mean the parties being able to resolve their dispute fairly, justly and amicably by applying law or legal principles. Traditional legal mechanisms for resolving disputes have been increasingly questioned as to whether they are actually capable of achieving justice in individual cases....   [tags: justice, traditional legal mechanisms]

Changes in the Environment Affect the Behavior and Physiological Aspect of an Organism

- The changes in the environment affect the behavior and physiological aspect of an organism. One important concept that further supports such phenomenon is heterochrony. Heterochrony is described to be the evolution of ontogeny, which is the development of an individual from its earliest stage to maturity. It takes hundreds, even millions of years for evolution to occur. By studying the earliest chordates, one would be able to relate the changes and adaptations that have emerged to sustain life of primates today....   [tags: heterochronic processes]

Essay about How the Environment can Have Effects on Physiological Processes

- The environment is an extremely powerful factor when it comes to physiological processes. The environment in which we are in is able to have surprising impacts on humans, as well as other animal’s physiological processes. Rosenzweig et al. conducted an experiment on mice to find out how the environment has an effect on the size of our brain. Another psychologist, George Brainard researched on the effects blue light has on humans. Both studies were able to show outstanding results on how the environment can have effects on physiological processes....   [tags: environment, physiological process, memory]

A Research Study On The Physiological Psychology Essay

- According to changing, Physiological psychology is the study of the physiological basis of how we think, connecting the physical operation of the brain with what we actually say and do. It is thus concerned with brain cells, brain structures and components, brain chemistry, and how all this leads to speech and action. It is also important to understand how we take in information from our five senses. Several persons contributed to the development of physiological psychology; such as Charles Darwin who were a biologist and whose theory of evolution revolutionized biology and strongly influenced early psychologists, René Descartes a philosopher and mathematician, Hermann von Helmholt...   [tags: Psychology, Brain, Nervous system]

Essay about The Defense Mechanism

- Defense mechanism, in psychoanalysis, any of a variety of unconscious personality reactions which the ego uses to protect the conscious mind from threatening feelings and perceptions. Sigmund Freud first used defense as a psychoanalytic term (1894), but he did not break the notion into categories, viewing it as a singular phenomenon of repression. His daughter, Anna Freud, expanded on his theories in the 1930s, distinguishing some of the major defense mechanisms recognized today. Primary defense mechanisms include repression and denial, which serve to prevent unacceptable ideas or impulses from entering the conscience....   [tags: Defense Mechanisms]

Mechanisms of LSD Essay

- Mechanisms of LSD: a Glimpse into the Serotonergic System In 1938, Albert Hoffman discovered, invented a substance that would revolutionize the American drug culture forever and would change how we, as psychologists and biologists, thought about psychosis. That substance was LSD. A simple molecule, LSD has the potency that no other drug has. Only a drop will produce the desired hallucinations and euphoria. In addition, it does not seem to be physically addicting, although tolerance to the drug can develop in as few as three days but disappears after week of abstinence....   [tags: Biology Essays Research Papers]
