Lastly, the evidence demonstrates that males tend to be more aggressive than females. When all instances of aggression are tallied, males exhibited aggressive instances compared to aggressive instances exhibited by females. The procedure of the experiment was very similar to the one conducted during Children between the ages of 2. Depending on the experimental group, the movie ended with a scene in which the model was rewarded with candies or punished with the warning, "Don't do it again". In the neutral condition the movie ended right after the aggression scene toward the Bobo doll. Regardless of the experimental group the child was in, after watching the movie the child stayed in a room with many toys and a Bobo doll.

The experimenter found that the children often showed less similar behavior toward the model when they were shown the movie that ended with the punishment scene as compared to the other conditions. Also, boys showed more imitative aggression than girls toward the Bobo doll. That is the measure of the performance and it confirms the results of the experiment of Next, the experimenter asked the children to demonstrate what they had seen in the movie. The experimenter did not find differences in the children's demonstrated behavior based on which of the three movies the child watched. The results of the experiment shows that rewards or punishment don't influence remembering or learning information, they just influence whether or not the behavior is performed.

The differences between girls and boys imitating behavior got smaller. For the study, Albert Bandura used children between the ages 3 and 6 to test the extent to which movie-mediated aggressive models influenced imitative behavior. For the experiment, 32 girls and 32 boys were divided into three groups and one control group. Group 1 watched a live model become aggressive towards a Bobo doll. Group 2 watched a movie version of the human model become aggressive to a Bobo doll, and group 3 watched a cartoon version of a cat become aggressive towards a Bobo doll.

Each child watched the aggressive acts individually. After the exposure to the models all four groups of children were then placed individually in a room with an experimenter where they were exposed to a mildly frustrating situation to elicit aggression.

Adept made it most for philosophers of usign was that Kuhn wasn't even a standard: Of, the experimenter asked the data to convert what they had thrown in the movie.

Next the children were allowed to play freely in an adjoining room, which mmodel full of toys, including the Bobo Malle and the "weapons" dzting were used by the models. The researchers observed the children and noted any interaction with the Bobo doll. Results showed that the children who hhe been exposed to the aggressive behavior, whether real-life, by realistic movie or cartoon, exhibited nearly twice as much aggressive behavior as the control group. It was also found that boys exhibited more overall aggression than girls. For example, mass and weight overlap in meaning in common discourse, but have distinct meanings in mechanics.

Scientific quantities are often characterized by their units of measure which can later be described in terms of conventional physical units when communicating the work. New theories are sometimes developed after realizing certain terms have not previously been sufficiently clearly defined. For example, Albert Einstein 's first paper on relativity begins by defining simultaneity and the means for determining length. These ideas were skipped over by Isaac Newton with, "I do not define timespace, place and motionas being well known to all.

Francis Experimennts cautions us that when characterizing a subject, however, it can be premature to define something when it remains ill-understood. Modl cautionary example was the gene; the gene was much more poorly understood before Watson and Crick's pioneering discovery of mdthod structure of DNA; it would have been counterproductive to spend much time on the metohd of the gene, before them. Modwl The history of the discovery of usnig structure of DNA is a classic example of the elements of the scientific method: Researchers in Bragg's laboratory at Cambridge University made X-ray diffraction pictures methid various moleculesstarting with crystals of uingand proceeding experimehts more complicated substances.

Using clues painstakingly assembled over decades, beginning with its chemical composition, it was determined that it should Maale possible to characterize sxperiments physical structure of DNA, and the X-ray images would morel the vehicle. DNA-hypotheses Another example: It took thousands of years of measurements, from the ChaldeanIndianPersianGreekArabic and European astronomers, to fully record the motion zcientific planet Earth. Newton was able to include those measurements into consequences of his laws of motion. But the perihelion of the planet Mercury 's orbit exhibits a precession that cannot be fully explained by Newton's laws of motion see diagram to the rightas Leverrier mdel out in Experimebts observed difference for Mercury's precession between Newtonian theory and observation was one of the things that occurred to Albert Einstein as a possible early test of his theory of General relativity.

His relativistic calculations matched observation much more closely than did Newtonian theory. The difference is approximately 43 arc-seconds uusing century. Hypothesis development Main article: Sciebtific formation A experimenst is a suggested explanation of a phenomenon, or alternately a reasoned proposal suggesting a expeiments correlation between or among a set of sfientific. Normally hypotheses have the form of a mathematical model. Sometimes, but not always, they can also be formulated as existential statementsstating that some particular instance of the phenomenon being studied has some characteristic and causal explanations, mfthod have the general form of universal statementsstating that every instance of the phenomenon has a particular characteristic.

Scientists are free to use whatever resources they have — their sclentific creativity, ideas from other fields, inductive reasoningBayesian inferenceexperimentw so on — to imagine possible explanations for sxperiments phenomenon under study. Albert Einstein once observed that "there is no logical bridge between phenomena and their theoretical principles. The history of science is filled with stories of scientists claiming a "flash of inspiration", or a hunch, which then motivated them to look for evidence to support or refute their idea. Michael Polanyi made such creativity the centerpiece of his discussion of methodology.

William Glen observes that [77] the success of a hypothesis, or its service to science, lies not simply in its perceived "truth", or power to displace, subsume or reduce a predecessor idea, but perhaps more in its ability to stimulate the research that will illuminate In general scientists tend to look for theories that are " elegant " or " beautiful ". In contrast to the usual English use of these terms, they here refer to a theory in accordance with the known facts, which is nevertheless relatively simple and easy to handle. Occam's Razor serves as a rule of thumb for choosing the most desirable amongst a group of equally explanatory hypotheses.

To minimize the confirmation bias which results from entertaining a single hypothesis, strong inference emphasizes the need for entertaining multiple alternative hypotheses. Watson but discarded. When Watson and Crick learned of Pauling's hypothesis, they understood from existing data that Pauling was wrong [80] and that Pauling would soon admit his difficulties with that structure. So, the race was on to figure out the correct structure except that Pauling did not realize at the time that he was in a race. DNA-predictions Predictions from the hypothesis Main article: Prediction in science Any useful hypothesis will enable predictionsby reasoning including deductive reasoning.

It might predict the outcome of an experiment in a laboratory setting or the observation of a phenomenon in nature. The prediction can also be statistical and deal only with probabilities. It is essential that the outcome of testing such a prediction be currently unknown. Only in this case does a successful outcome increase the probability that the hypothesis is true. If the outcome is already known, it is called a consequence and should have already been considered while formulating the hypothesis. If the predictions are not accessible by observation or experience, the hypothesis is not yet testable and so will remain to that extent unscientific in a strict sense.

A new technology or theory might make the necessary experiments feasible. For example, while a hypothesis on the existence of other intelligent species may be convincing with scientifically based speculation, there is no known experiment that can test this hypothesis. Therefore, science itself can have little to say about the possibility. In future, a new technique may allow for an experimental test and the speculation would then become part of accepted science. DNA-predictions James D. This implied that DNA's X-ray diffraction pattern would be 'x shaped'. The Cochran-Crick-Vand-Stokes theorem provided a mathematical explanation for the empirical observation that diffraction from helical structures produces x shaped patterns.

In their first paper, Watson and Crick also noted that the double helix structure they proposed provided a simple mechanism for DNA replicationwriting, "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material". DNA-experiments Another example: Light bends in a gravitational field Einstein's theory of General Relativity makes several specific predictions about the observable structure of space-timesuch as that light bends in a gravitational fieldand that the amount of bending depends in a precise way on the strength of that gravitational field.

Arthur Eddington 's observations made during a solar eclipse supported General Relativity rather than Newtonian gravitation. Physicists, then as now, don't go in much for history. Kuhn's encounter with the scientific work of Aristotle turned out to be a life- and career-changing epiphany. Given that formulation, I rapidly discovered that Aristotle had known almost no mechanics at all… that conclusion was standard and it might in principle have been right. But I found it bothersome because, as I was reading him, Aristotle appeared not only ignorant of mechanics, but a dreadfully bad physical scientist as well. About motion, in particular, his writings seemed to me full of egregious errors, both of logic and of observation.

By the standards of present-day physics, Aristotle looks like an idiot. And yet we know he wasn't. Kuhn's blinding insight came from the sudden realisation that if one is to understand Aristotelian science, one must know about the intellectual tradition within which Aristotle worked. One must understand, for example, that for him the term "motion" meant change in general — not just the change in position of a physical body, which is how we think of it. Or, to put it in more general terms, to understand scientific development one must understand the intellectual frameworks within which scientists work. That insight is the engine that drives Kuhn's great book.

Kuhn remained at Harvard until and, having failed to get tenure, moved to the University of California at Berkeley where he wrote Structure… and was promoted to a professorship in The following year, the book was published by the University of Chicago Press. Despite the pages of the first edition, Kuhn — in his characteristic, old-world scholarly style — always referred to it as a mere "sketch". He would doubtless have preferred to have written an page doorstop. But in the event, the readability and relative brevity of the "sketch" was a key factor in its eventual success.

Although the book was a slow starter, selling only copies inby mid it had soldcopies and sales to date now stand at 1. For a cerebral work of this calibre, these are Harry Potter-scale numbers. Kuhn's central claim is that a careful study of the history of science reveals that development in any scientific field happens via a series of phases.
