magnetic field

Examples of magnetic field in the following topics:

• Brain Imaging Techniques

  • Magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI) scans are the form of neural imaging most directly useful to the field of psychology.
  • An MRI uses strong magnetic fields to align spinning atomic nuclei (usually hydrogen protons) within body tissues, then disturbs the axis of rotation of these nuclei and observes the radio frequency signal generated as the nuclei return to their baseline status.

• Introduction to Biomedical Therapies

  • A more recent alternative to ECT is transcranial magnetic stimulation (TMS), a procedure approved by the FDA in 2008 that uses magnetic fields to stimulate nerve cells in the brain to improve depression symptoms; like ECT, it is used when other treatments have not worked (Mayo Clinic, 2012).
  • Psychosurgery has always been a controversial medical field.

• Studying the Brain

  • Many schools of thought within the field have come and gone since then; some, like behaviorism, have persisted and evolved if they stood up to scientific study; others, like phrenology, have faded as they have lost credibility.
  • Neuroscience is a relatively new field, but the more research that is done, the more it appears that much of human behavior and mental processes—the key interests for psychological study—are intimately intertwined with activity in the brain.
  • Cancerous lesion (i.e., tumor) in the brain's right cerebral hemisphere from lung cancer, shown on T1-weighted magnetic resonance imaging with intravenous contrast.
  • Trace the history of brain science in the field of psychology

• Careers in Psychology

  • Psychology is a very broad field that offers a wide range of career options.
  • Psychology is a very broad field, and there are many career options available for graduating students of psychology.
  • There are several subfields within the field I-O psychology: for instance, personnel psychology focuses on the selection and evaluation of workers, while organizational psychology examines the effects of work environment and management styles on worker motivation, job satisfaction, and productivity.
  • This image depicts the location of the hypothalamus using magnetic resonance imaging (MRI).

• Biopsychology

  • The fields of behavioral neuroscience, cognitive neuroscience, and neuropsychology are all subfields of biological psychology.
  • Neuroimaging tools, such as functional magnetic resonance imaging (fMRI) scans, are often used to observe which areas of the brain are active during particular tasks in order to help psychologists understand the link between brain and behavior.
  • Magnetic resonance imaging (MRI) scans of the head are often used to help psychologists understand the links between brain and behavior.
  • Three types of scans include (left to right) PET scan (positron emission tomography), CT scan (computed tomography), and fMRI (functional magnetic resonance imaging).

• Genetic Basis of Intelligence and Learning

  • Modern brain imaging techniques, such as functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG), now make it possible to essentially watch the brain as it learns.
  • Although the field is young, it is expected that with new technologies and new ways in which to observe learning, the paradigms of what students need and how students learn best will be further refined with actual scientific evidence.

• Introduction to Social Psychology and Social Perception

  • The field of social psychology has traditionally been described as a bridge between psychology and sociology.
  • There are some important differences in the way that psychological social psychologists and sociological social psychologists approach the field of study.
  • This field is specifically concerned with the way feelings, thoughts, beliefs, intentions, and goals are constructed, and how such psychological factors, in turn, influence interactions with others.
  • The field of social psychology consists of the overlapping foci of psychology and sociology.
  • Define the goals, questions, and approaches of the field of social psychology

• Neural Correlates of Memory Storage

  • Recent functional-magnetic-resonance-imaging (fMRI) studies detected working memory signals in the medial temporal lobe and the prefrontal cortex.

• Early Roots of Psychology

  • The field of psychology emerged as a scientific discipline in the 19th century, but its roots go back to ancient philosophy.
  • These philosophical roots played a large role in the development of the field.
  • The fields of psychoneuroimmunology and behavioral medicine explicitly focus on this interconnection.
  • Psychology as a self-conscious field of experimental study began in 1879, when German scientist Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research in Leipzig.
  • Describe the philosophical roots of what would later become the field of psychology

• Social Psychology

  • The field of social psychology studies topics at both the intrapersonal level (pertaining to the individual), such as emotions and attitudes, and the interpersonal level (pertaining to groups), such as aggression and attraction.
  • The field is also concerned with common cognitive biases—such as the fundamental attribution error, the actor-observer bias, the self-serving bias, and the just-world hypothesis—that influence our behavior and our perceptions of events.
  • During the 1930s, Gestalt psychologists such as Kurt Lewin were instrumental in developing the field as something separate from the behavioral and psychoanalytic schools that were dominant during that time.
