Seligman's Theory of Preparation: Explaining Phobias
There are many theories that try to explain the acquisition of phobias. Why do you think some phobias are more common than others? In this article we will know Seligman's theory of preparation, which tries to explain this phenomenon.
The theory alludes to two main concepts, preparation (phylogenetic aspects) and predisposition (ontogenetic aspects) for the development of phobias. If you want to know why you are more likely to be afraid of heights, fire or snakes, than to be afraid of doors, for example, keep reading!

Seligman preparation theory: characteristics
Martin Seligman was the researcher who established the grooming theory. According to this theory, the organism is phylogenetically prepared (through an evolutionary process of the species) to associate or easily learn the relationship between certain stimuli (biologically primed stimulus to be associated with a answer), because this learning is adaptive.
Seligman's theory of priming arises in opposition to the principle of equipotentiality, which held that all stimuli could elicit phobic responses. Thus, according to Seligman, only some stimuli would be prepared to cause phobias. These would be dangerous stimuli, which put the survival of the species at risk, such as lions, snakes, heights, fire, etc.
Seligman, in a way, conceives phobias as powerful adaptation tools of the species, which increase the probability of survival and perpetuation of it.
Central concepts of the theory
Seligman's preparation theory is made up of two fundamental concepts, which are as follows.
1. Preparation
It alludes to phylogenetic aspects, typical of an evolutionary process of the species. There are three types of stimuli in terms of their "grade" or level of preparation:
1.1. prepared stimuli
Is about biologically prepared stimuli to be learned as noxious (for example, associating an unpleasant taste with a stomach ache).
1.2. unprepared stimuli
They are stimuli that end up being acquired with certain tests (for example in laboratory situations; light beams that associate with an aversive stimulus after several trials). It would be “neutral” stimuli, without a biological load to be acquired, in this sense.
1.3. counterprepared stimuli
They are the stimuli that are impossible to learn, that is, impossible to associate with a certain concept (for example, an electric shock, which is not associated with a tummy ache).
2. Predisposition
It refers to ontogenetic aspects, that is, to individual differences resulting from the development of the organism.
The Garcia effect
From Seligman's theory of preparation, another interesting and widely used concept arises in psychology of learning, which is related to the concept of "preparation" already mentioned: the effect Garcia.
This effect tells us about an aversion to the acquired taste; was discovered from the study of rats, finding that they associated an unpleasant taste with a stomach ache, since they are prepared to associate such a taste with the disease (so that we understand each other, due to its "direct" relationship or "similarity" between the taste and the belly).
On the other hand, rats are counterprepared to establish an association between taste and electric shocks (because of their null "similarity" or relationship between a stimulus).
The Garcia effect demonstrates or explains the easy acquisition of conditioned nausea in cancer patients; that is, these patients end up associating the taste (bad taste) of chemotherapy with subsequent vomiting, and therefore end up conditioning.
Characteristics of phobias
According to Seligman's theory of preparation, phobias have 4 characteristics consistent with the concept of preparation:
1. Selectivity
Certain stimuli produce fear more easily than others. This implies that phobias, as we have already mentioned, are crucial for the survival of the species.
2. easy acquisition
One trial is enough to acquire a phobia (and it does not necessarily have to be a traumatic stimulus).
3. resistance to extinction
phobias are strongly resistant to extinction (resistant to disappearing). This is the most characteristic aspect of phobias, according to Seligman's preparation theory.
4. Irrationality
Finally, there is a disproportion between the real danger of the stimulus and the anxiety response it produces, that is, phobias are irrational.
Reformulation of the theory
Öhman reformulated Seligman's theory of preparation, and differentiated two types of phobias, according to their evolutionary origin:
1. non-communicative origin
These are phobias of heights, closed spaces, agoraphobia, etc. That is to say, do not have a “social” or communicative function.
2. communicative origin
They would be the phobias that fulfill a communicative role between species; for example, animal phobias and social phobias.
Animal phobias would be interspecific of the species (they appear not only in humans), and would involve escape or defense, especially in childhood. On the other hand, social phobias would be intraspecific (typical of the human species), causing dominance and submission responses, frequently appearing in adolescence.
