These include the experimental method experimentcorrelational studies twin studies and case studies, depending on the factors investigated. This essay will focus only on the experiment and the case study. The experiment is used at the biological level of analysis for several reasons.
The experiment is carried out in a controlled environment in which one variable is changed to demonstrate causality. It often includes quasi-experiments based on comparing different groups e. The experiment is used due to the properties of the method which prove to be beneficial to research at the biological LoA in certain cases.
The greatest advantage of the experimental method is that it allows us to establish cause and effect relationships. In general, the IV is the cause, and the DV the effect. The careful control of variables helps ensure a high level of internal validity since uncontrolled variables or "unknowns" are avoided.
Another major advantage is that a carefully controlled and documented study can be replicated. However, often experimental studies involve the creation of an artificial environment or level of control.
Thus conditions don't necessarily reflect the real world situation and this causes problems with ecological validity. It also requires rigorous adherence to rules to avoid experimenter effects various ways in which the experimenter's expectancies, personal characteristics, misrecording of data, etc.
They investigated the effects of environment on cortex size a study of Brain plasticity. The characteristics of the experimental method allowed the researchers variable control of the environments the adult rats were placed in.
They could investigate the effect of an independent variable chosen and controlled by them, the environment, on a dependent variable out of their control, the cortex size of rats. Numerous studies have replicated these findings in animals, they are however difficult to replicate in humans due to methodological an ethical reasons.
Replicability was made possible by the careful control ensured by the experimental design. Post-mortem examination of the brains of the rats revealed that the brains of those who spent time in the enriched environment had a thicker cortex and more connections between neurons.
Thus, the causality of environment on cortex size was demonstrated in the experiment.
This study has huge implications since it suggests that the brain does change after adulthood and that it does not take monumental efforts or special drugs to achieve these results.
Another experimental method often used at the biological LoA is the correlational study. This examines the relationship between two variables but cannot determine causality cause and effect. A correlation is the association that is found between two variables.
Correlational studies are often used at the biological level of analysis to study the role of nature and nurture in a specific behavior or property by comparing MZ and DZ twins.
Its strengths are that it allows the study of hypotheses that cannot be examined directly and that more data on more variables can be collected much more quickly than a true experiment. Additionally, problems of interpretation are reduced when no association is found.
Even when strong correlations are found, it may be obvious that no causal relationship exists.The Department of Biological Sciences is pleased to announce our week Interdisciplinary Summer Research Program in Biology starting Monday, June 3 and finishing with our research symposium on Wednesday, August 7, The Abrams group uses molecular simulations to address questions in biological and materials sciences primarily centered on structure/function relationships.
The group has made efforts to develop and implement new molecular simulation methods for statistically accurate prediction of energetics and rates of molecular-level processes. Discuss how and why particular research methods are used at the biological level of analysis. Introduction.
State what you are doing in the essay. Introduction. Microfluidic is a well understood physic domain and can be now used to develop tools for cell biology.
By simply miniaturizing macroscopic systems and taking advantage of the possibility of massive parallel processing, some microfluidic chips enable high-throughput biological experiments.
This essay will attempt to offer a balanced review of how and why particular research methods are used at the biological level of analysis (BLA). Define the biological level of analysis The biological level of analysis (BLA) states that all cognitions, emotions and behaviours have a physiological basis.
Similarly, proposals with research in mathematics or statistics that is not tied to a specific biological problem should be submitted to the appropriate DMS program at NSF. Proposals designed to create new software tools based on existing models and methods will not be accepted in this competition.
