Powerpoint on Lashley and Hebb

Solution Preview

First, search for the background information about these two men. PowerPoint is both easy and hard because you have to reduce everything to "bullet points" of information, since the slide does not allow much text.

Check Perdue University's Online Writing Lab (OWL) for properly formatting the APA citations on the last slide(s) of your presentation, the References slide(s) - and be sure to note where your information comes from as you search for it.

Once you have the information you want to use, consider what it has to say in order to determine how you will go about organizing the PP presentation. This is similar to writing a paper, except your 'sentences' will be very short. It still needs organization.

Karl Lashley: http://www.uic.edu/depts/mcne/founders/page0054.html DR. K.S. LASHLEY
(1890-1958) Born and educated in the United States, Lashley began to collaborate with Shepherd J. Franz in the study of intelligence and the role of the frontal lobes. He promulgated the theory of cortical specialization for sensory and motor functions. He challenged the ongoing concept of cortical localization. The controversy between localization and holistic emphasis of brain function was brought into focus by Lashley. He is remembered as a great psychologist who approached learning and memory by assessing the effects of brain damage in laboratory animals.

Lashley's later work included research on brain mechanisms related to sense receptors, and on the cortical basis of motor activities. He studied many animals, including primates, but his major work was done on the measurement of behavior before and after specific, carefully quantified brain damage in rats. He trained rats to perform specific tasks, then lesioned specific areas of the rat cortex, either before or after the animals received the training. The cortical lesions had specific effects on acquisition and retention of knowledge-memory. This work led Lashley to another area of study, the one that he focused on during the rest of his career, and the area he became the most famous for: cerebral localization.
The study of cerebral localization was an area in psychology that generated numerous controversies in the first half of the twentieth century. Many scientists including Franz Joseph Gall, Paul Broca, and others believed that particular local areas in the brain were responsible for particular brain functions, therefore advocating for exact cerebral localization. On the other side, researchers like Marie-Jean-Pierre Flourens held that brain ...
