El caso de los condicionales con disyunciones incluidas en sus antecedentes. Talca, Chile. E-mail address: milopez utalca. Te mental models theory and the mental logic theory are two alternative theories trying to explain, describe, and predict human reasoning. Both of them are consistent with most the experimental results reported in cognitive science literature.

Therefore, it is hard to decide which is the correct one. In this paper, I what are the two basic types of inference what is the legal definition of show cause the predictions of both theories concerning the conditionals with disjunctions embedded into their antecedents are different, and that certain results that can be found in the literature seems to support the predictions of the mental logic theory about this kind of conditionals.

Keywords: Conditional, disjunction, formal rules, mental logic, mental models. La teoría de los modelos mentales y la teoría de la lógica mental son dos teorías love yourself healthy quotes que tratan de explicar, describir y predecir el razonamiento humano. Ambas son consistentes con la mayor parte de los resultados experimentales presentados en la literatura de la ciencia cognitiva.

What are the two basic types of inference este trabajo, argumento que las predicciones de las dos teorías con respecto a los condicionales con disyunciones incluidas en sus antecedentes son diferentes y que ciertos resultados que se pueden encontrar en la literatura parecen apoyar las predicciones de la teoría de la lógica mental acerca de este tipo de condicionales. Palabras clave: Condicional, disyunción, reglas formales, lógica mental, modelos mentales.

At present, there are several theories about human reasoning. In this paper, I will address two of them that have a great explicative and predictive scope: the mental models theory from now on, M-Mt and the mental logic theory from now on, M-Lt. The approach of M-Mt e. According how do you use the word effect in a sentence this theory, people do not make inferences applying formal rules, but thinking about the combinations of possibilities that can be attributed to the propositions.

On the other hand, M-Lt e. Following M-Lt, people reason using formal rules or schemata. However, as far as this last theory is concerned, it is important to highlight that it is not equivalent to classical propositional calculus or systems such as that of Gentzen Likewise, M-Lt is different to other syntactic approaches to human reasoning e. M-Lt only accepts the rules of standard propositional calculus that are compatible with experimental results.

Besides, all the rules do not have the same what are the two basic types of inference in M-Lt. In my view, this what is p.p.c between M-Lt and other syntactic proposals or systems needs to be evinced because M-Lt is often misunderstood and considered to be equivalent to other approaches or calculi.

It is really difficult to find proofs or facts that reveal which of these two theories M-Mt and M-Lt is the theory that can better explain and predict the human cognitive phenomena. However, I think that there are certain conditional inferences that can show this and that the results of experiments using such inferences can prove that M-Lt is a better option. Those inferences correspond to a version of Chrysippus' Modus Ponens in which the antecedent of the conditional is not a are cornflakes bad for ibs variable, but different propositional variables linked by means of disjunctions.

The inferences of this kind are important because, as I will explain below, the predictions of M-Mt and M-Lt concerning them are different and, as indicated, the experimental results seem to support those of M-Lt. The fact is that, according to M-Mt, it can be said that such versions should be more difficult to solve than the inferences based on the original structure of Modus Ponens.

On the other hand, M-Lt holds that both the versions with disjunctions embedded into the antecedent of the conditional and the original versions correspond to Core Schemata that people use whenever they can do it and that none of the two inferences is harder that the other one. The key is that, as mentioned, the results offered by the literature -in particular, some experiments carried out by some what is machine readable format of M-Lt- appear to demonstrate that, indeed, individuals use the formal rules of M-Lt.

My aim in this paper is to prove this last idea and to argue in favor of it. To do so, I will start by commenting the account of M-Mt on conditionals and disjunctions. Then I will expose how the mentioned inferences are considered by M-Lt and why this theory thinks that both of them are equivalent in difficulty level. Finally, I will what are the two basic types of inference which the exact predictions of M-Mt concerning the inferences are and why those predictions are inconsistent with certain experimental results of cognitive science literature.

As said, M-Mt claims that people reason by considering the combinations of possibilities of propositions. In particular, as far as conditionals and disjunctions are concerned, the possibilities or 'mental models' that this theory proposes are -as indicated, for example, in Johnson-Laird - the following:. Conditional if p then q :. Disjunction p or q :. This means that this theory states that, in principle, people tend to pay attention to only a combination of possibilities when they are thinking about a conditional, and that that combination is p and q.

In the case of disjunction, which will be considered in this paper as inclusive, the initial combinations are, as shown, three: p and q, p alone, and q alone. However, when individuals' processing effort is greater, they can detect the 'fully explicit models', i. The fully explicit models of conditional are -according to works supporting M-Mt such as Johnson-Laird - as follows:. The missing combination i. Likewise, the fully explicit models that, following M-Mt, can be linked to disjunction are these ones:.

Given that both conditional and disjunction are present in the version of Modus Ponens indicated above, the predictions of M-Mt on that kind of inference are obvious. Nevertheless, before analyzing such predictions, it can be opportune to describe them in more details and to explain why they are so important and relevant in M-Lt. As it is well known, the original version of Modus Ponens has this formal structure:. As said, this is a very relevant rule in M-Lt.

It is a Core Schema, i. In particular it is the schema 7 in Braine and O'Brien b and, for this reason, from now on, I will refer to it as 'S7'. But the version with disjunctions embedded into the antecedent of the conditional is very important for M-Lt too. Its formal structure is this one:. This schema is a Core Schema of M-Lt as well. In particular it is the schema 2 in Braine and O'Brien b. For this reason, I will call it 'S2' in the next pages.

Thus, the most important point here is that, as mentioned, both S7 and S2 are Core Schemata of M-Lt and that, therefore, they are generally used by people in an automatic and routine way. Tis in turn means that, according to M-Lt, neither S7 nor S2 are hard to apply. In fact the proponents of M-Lt tried to prove this last idea by means of empirical experiments and their results seemed to confirm that, certainly, they are very ease schemata that people constantly use without any special why neutral is grounded in star connection. A curious datum in this regard was, nonetheless, that it was found that, despite the fact that the structure of S2 appears to be more complicated, it is easier to apply than S7.

This is because, although the differences were not very great, the participants made more mistakes when they had to apply S7 than when they had to apply S2. This reveals that, as what are the two basic types of inference, although the difference is not very relevant, if one of these two schemata is more difficult, that schema is S7.

These results are really interesting if the goal of this paper is taken into account. As I understand it, from the theses of M-Mt explained in the previous section, it can be drawn the conclusion that, according to this last theory, S2 is harder to S7 and that, for this reason, the percentage of errors of S2 would have to be higher. I will argue this idea in the next section. The framework of M-Mt implies that the inferences that refer to what are the two basic types of inference models are more difficult that those that need less models.

If this thesis is correct, form the perspective of M-Mt, S2 should be harder than S7. I will show why. Firstly, I will take only the mental models into account. The inferential process in the case of S7 would be as follows:. The mental model of the first premise would be:. The what are the two basic types of inference premise states that x is true. Therefore, it is only possible that y is true too, since no other combination is considered. Regardless of what the second premise indicated x 1 or x 2it is evident that, to conclude q, individuals must pay attention to the previous three models.

But, if we imagine a situation in which the participants consider all the fully explicit models, the prediction of M-Mt does not change. For S7, the models would be these ones:. By stating x, the second premise eliminates the last two models and y is concluded. In any case, in papers such as Khemlani et al. Khemlani et al. However, what is important here is that S7 requires three fully explicit models and that S2 refers to five fully explicit models.

The prediction of M-Mt hence continues to be inconsistent with the mentioned experimental results. In such a scenario, the mental models of the first premise of S2 would be four:. Therefore, if the thesis of M-Mt were correct, S2 would be four times more difficult than S7 remember that the mental model of the first premise of S7 is just one. Because the fully explicit models of the first premise of S7 are three, the difference is evident and leads one to think that, if n has a high value, the prediction of M-Mt is not simply that S2 is harder, but that it is unfeasible.

Therefore, it can be said that the experimental results obtained by the proponents of M-Lt seem to be compatible only with their theory, i. The idea that different cognitive theories can account for a same experimental result is not new see, for example, López-Astorga, a, b, c, For this reason, it is always important to identify aspects, scenarios, or situations in which the predictions of the different theories are not the same, since such aspects, scenarios, or situations can show which theory is more appropriate.

As mentioned, both M-Mt and M-Lt can describe and predict most cognitive phenomena, but I think that I have shown in this paper a particular case in which the predictions of those two theories are clearly different. As I have also why attending events is important, certain experimental results seem to support the prediction of M-Lt. However, because this paper has what are the two basic types of inference addressed a very particular kind of inference, maybe further research regarding this issue is needed.

In any case, there are some points that it is always necessary to remember. It is what are the two basic types of inference true that many experimental results reported by the literature cannot be explained by calculi such as standard propositional calculus or frameworks such as that of Rips Nevertheless, the mental logic proposed by M-Lt is not similar to such calculi and frameworks. In fact, it is very different because it only admits the rules what does living mean in biology schemata that, according to empirical studies, people really use.

This point is especially relevant because, in many occasions, when it is proved that a certain experimental result is inconsistent with a particular syntactic approach, it can be observed a trend to extrapolate the conclusions and to consider all the syntactic what are the two basic types of inference including, of course, M-Lt to be incorrect. But another point that is important is the idea that M-Lt does not require exclusivity O'Brien, This means that maybe the problem studied what are the two basic types of inference this paper does not only refer to two options: to accept M-Mt or to assume M-Lt.

Perhaps a third option is possible and human mind can resort, depending on the circumstances, both to semantic models and to syntactic rules. Theses akin to this one have also been suggested in other papers e. The author, who is also the main researcher of that Project, would like to thank the mentioned institutions for their help in funding this paper.
