What is procedural fidelity ABA?
Also known as treatment integrity, this is a measure of how reliably a treatment is being delivered as it was designed/written. To calculate procedural fidelity, write out a list of the steps involved in performing the treatment and record whether each step was being performed correctly.
What term means bounce in data ABA?
Variability. When all conditions during a given phase of an experiment are held constant and repeated measures of the behavior result in a great deal of “bounce” in the data.
What is direct measurement in ABA?
Direct Measurement is recording behavior as it occurs in either natural or contrived settings. Direct measurement can be continuous or discontinuous. Continuous measurement records ALL instances of Behavior, examples of continuous recording would be frequency, duration, latency, intensity.
What is measurement artifact?
Measurement artifact. Something that appears to exist because of the way it is measured – discontinuous measurement, poorly scheduled measurement periods, insensitive/ limiting measurement scales) (artifact – when data give a misleading picture of the behavior because of the way it is measured)
What is reactivity ABA?
Reactivity. Definition. refers to the effects of an assessment procedure on the behavior being assessed. Reactivity is most likely when observation is obtrusive, that is, the person being observed is aware of the observers presence and purpose. Term.
What is a reactive behavior?
Reactivity is a phenomenon that occurs when individuals alter their performance or behavior due to the awareness that they are being observed. The change may be positive or negative, and depends on the situation.
How can we prevent reactivity?
To avoid reactivity, they would have to stay hidden or get their data from a hidden surveillance camera. And, they would have to keep their study a secret until it was completed. In research where unobtrusive observation is not possible, scientists most often use a blind experiment design.
What is the key to reactivity?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.
Which is an example of a reactive chemical?
Reactive chemicals are classified as explosives, strong oxidizing agents, water reactives, air reactives, and special organic compounds. Many of these compounds become more sensitive as they age or dry out. Examples include peroxides, nitroglycerin, and TNT.
What is an example of reactivity?
Reactivity is the ability of matter to combine chemically with other substances. Some kinds of matter are extremely reactive; others are extremely unreactive. For example, potassium is very reactive, even with water. When a pea-sized piece of potassium is added to a small amount of water, it reacts explosively.
What is highly reactive?
Highly reactive chemistry is a terminology used to describe chemical reactions that are particularly challenging to handle and develop due to the potentially hazardous and/or energetic nature of the reactants, intermediates and products that are present during synthesis.
Which metal is highly reactive?
potassium
How can you tell which metal is more reactive?
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
Which elements are more reactive?
Reactivity of Group 1 Elements Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
Is Potassium the most reactive metal?
Potassium is in the most reactive group of elements, the alkali metals, but it’s not the most reactive metal within the group. Within the alkali metals family, reactivity increases with increasing atomic number. This makes Francium the most reactive, followed by cesium, rubidium, potassium, sodium and lithium.
Is oxygen highly reactive?
Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. Free oxygen is too chemically reactive to appear on Earth without the photosynthetic action of living organisms, which use the energy of sunlight to produce elemental oxygen from water.
What are the least reactive metals?
Silver, gold, and platinum are metals with the least reactivity. They are found in nature.
Which metal is less reactive copper or iron?
Iron displaces copper from its solution. Therefore, copper is less reactive than iron. Copper does not displace any metal therefore it is the least reactive.
Which metal is more reactive than calcium?
The reactivity series
| Element | Reaction with water |
|---|---|
| Potassium | Violently |
| Sodium | Very quickly |
| Lithium | Quickly |
| Calcium | More slowly |
Which metal is more reactive iron or zinc?
Answer : Zinc is more reactive than iron. Zinc is placed above iron in the reactivity series. For example, Zinc can displace iron from ferrous sulphate solution to form zinc sulphate and iron.
