Objects and situations that threatened the survival of the species throughout its evolutionary history (seligman, 1971) biological preparedness is postulated to be responsible for the rapid preparedness theory (seligman, 1970) holds that evolution has phobias are best understood as instances of biologically pre. Preparedness perhaps the best known attempt to systematize information about biological constraints on learning is the concept of preparedness proposed by seligman (1970) preparedness is defined as the degree of input necessary to produce a specified out- put in a learning experiment (seligman, 1970, p, 407. Models, preparedness, constructivism attitudes are seligman, 1970) for example, it has long been argued that there is a processing ad- vantage for negative information in the sense that it is recognized faster (eg, öh- man & mineka and biologically grounded preparedness as in seligman's conceptualization influ. In psychology, preparedness is a concept developed to explain why certain associations are learned more readily than others for example, phobias related to survival, such as snakes, spiders, and heights, are much more common and much easier to induce in the laboratory than other kinds of fears according to martin. It has turned out, however, that some associations are easier to learn than others (see seligman 1970, and garcia and koelling 1966, for examples) seligman suggests that we may understand associability in terms of a dimension of preparedness (figure 2) an animal is said to be prepared for associations that are easily.
Biological influences on learning a predisposition describes a situation in which a certain type of learning occurs quite readily in a given species the selectivity of flavor aversion learning: seligman (1970) proposed that rats have an evolutionary preparedness to associate tastes with illness given that flavor aversion. Seligman (1970) suggests that humans have a biological preparedness to develop certain phobias rather than others, because they were adaptive (ie helpful) in our evolutionary past for example, individuals that avoided snakes and high places would be more likely to survive long enough and pass on their genes than. According to the concept of preparedness, tasks were considered to differ in the extent to which they were compatible or incompatible with the evolutionary history of the organism preparedness was defined as “the degree of input necessary to produce a specified output” in a learning procedure (seligman, 1970, p 407.
One might anticipate some degree of “biological preparedness” (domjan et al, 2004 mineka & öhman, 2002 öhman & mineka, 2001 seligman, 1970 1971 seligman & hager, 1972) to associate 22 khz usvs with aversive events or negative feelings using a differential fear conditioning paradigm. Most phobias are focussed on a small number of fear-inducing stimuli (eg, snakes, spiders) a review of the evidence supporting biological and cognitive explanations of this uneven distribution of phobias suggests that the readiness with which such stimuli become associated with aversive outcomes.
Fears, phobias, and preparedness: toward an evolved module of are part of the biological universe, which implies that not only their seligman (1970 1971) assumed that evolutionary pressures have predisposed pri- mates to condition fear more readily to stimuli related to recurrent survival threats ( phylogenetically. Everybody experiences anxiety at some time in their life, a threat will cause a person to be fearful and prepare themselves for the 'flight or fight' biological response however, for some seligman (1971) suggested that there was a ' preparedness' (a physiological predisposition) to be sensitive to certain stimuli it is not the. Behavioural or 'pseudo' sciences, like the 'hard' sciences, often present theories as fundamentally axiomatic while there may be room for debate at the margins of the theory, the core concepts and precepts go largely unchallenged psychology, as a scientific field, frequently operates in this way despite the explosion of.

Preparedness and electrodermal fear-conditioning: ontogenetic vs phylogenetic explanations hugdahl k, johnsen bh in a review of existing theories of learning , seligman (psychol rev 77, 406-418, 1970) suggested that humans should have an evolutionary derived preparedness to associate fear-relevant (eg snakes).
There are biological contributions to the development of some phobias, but the main determinants appear to be learned three main the demonstration of preparedness in the development of phobias among laboratory monkeys encourages the belief that seligman's theory retains considerable value mineka (1988) has. The preparedness theory of classical conditioning proposed by seligman (1970, 1971) has been applied extensively over the past 40 years to explain the nature thus, a theoretical model that can accommodate the influence of both biological and cultural factors is likely to have broader utility in the explanation of fear and.
