When a cue (X) and an outcome are paired, X comes to elicit responding similar to that elicited by the outcome. This potential
is lessened if X is later presented by itself (i.e., experimental extinction). Extinction is interesting both for theoretical reasons
and because it is a model for exposure therapy, which is used to treat numerous psychological disorders. Conventionally,
extinction has been viewed as an isolated phenomenon unrelated to other response-attenuating treatments, whereas it is
actually but one of several instances of associative interference that reduce conditioned responding. Although much has been
learned about extinction from direct study, the larger associative-interference literature provides additional insight. Here we view extinction as new learning that is inconsistent with previously acquired knowledge (i.e., retroactive outcome interference). We provide an account of whether the acquisition or extinction memory will be expressed depending on the relative strengths of these two memories and the relative efficacies of their respective retrieval cues.

Em tal condição cultural residem, parece certo, questionamentos críticos fundamentais quanto aos tradicionais modelos éticos prescritivos, fundados na estabelecida metafísica ocidental grega. Esse o sentido, por exemplo, de propostas como a da ética da alteridade radical, do filósofo judeu e franco-lituano, Emmanuel Lévinas. Partindo da potente radicalidade crítica levinasiana, Freire (2002) empreendeu um desafiante diálogo com as psicologias do contexto da modernidade tardia. O presente exercício encontra-se inspirado nesse trabalho e ensaia, a partir de uma desleitura inventiva da Gestalterapia, introduzir um parâmetro de leitura no qual possa dar-se a promoção de uma superação ética de leituras nas quais essa abordagem é significada como psicoterapia do Eu, de pretensões ortopédicas e, assim, manifestamente violenta. Este é, pois, um discurso esperançoso, que pretende apontar para as possibilidades contemporâneas de uma psicoterapia ética.

Estimation methods for these data have mainly focused on classical maximum likelihood. In this paper we study possible improvements utilising a Bayesian MCMC approach to model this type of data. The classical and Bayesian approaches are compared with a Monte Carlo simulation experiment. The results show that the Bayesian approach improves the performance of the model, particularly with relatively small samples

The ability to understand or use language is more or less dependent on the memory capacity. Any person may know what s/he wants to say but may not be able to say it if the memory does not help. We use some form of memory in all aspects of language processing. Whatever we have in our mind is stored whether for seconds, hours, or years. By short-term memory, a person can remember different things for a period of seconds or minutes only. By rehearsal, the duration and the quantity of storage will increase. Therefore, rehearsal transforms the short-term memory into the long-term memory. This experiment, which examines the number of words recalled by different age groups after presenting a word list, reveals that the younger a person the more are the words he or she recalls. The experiment also reveals that semantically related words have greater chance to be remembered when they are compared with unrelated words.
Learning Capability: The Effect of Existing Knowledge on Learning

One plausible reason for this disparity in learning is the difference in the existing personal knowledge held in the particular area in which the knowledge increase happens. To understand this further, in this paper knowledge is modelled as a ‘system of cognitive schemata’, and knowledge increase as a process in this system; the effect of existing personal knowledge on knowledge increase is ‘the Learning Capability’. Learning Capability is obtained in form of a function; although it is merely a representation making use of mathematical symbolism, not a calculable entity. The examination of the function tells us about the nature of learning capability. However, existing knowledge is only one factor affecting knowledge increase and thus one component of a more general model, which might additionally include talent, learning willingness, and attention.

The problem domain of the investigation presented in this dissertation is knowledge increase. In particular the research is concerned with the process of knowledge increase. The research problem formulated is formulated a posteriori: “Which factors determine the increase of personal knowledge that occurs by absorbing a particular new knowledge of an individual, who is a member of an organization, and how these factors work?”
To explore and shed light on this problem a number of disciplinary boundaries were engaged and some models, tools, descriptions, etc. were borrowed from a number of related disciplines. These areas are briefly presented in the dissertation, restricting presentation to the relevant issues.
There are three models developed for this thesis and they are subsequently integrated into a fourth model. First the ‘Model of Learning Willingness’ (MLW) is developed to consider personal and organizational value systems. For this model, new concepts have been created, to indicate the position of new knowledge in both personal and organizational value systems. Stable and the unstable states of the model are identified as well as how it is possible to pass from one state to another as result of an interaction between the two value systems by means of influencing each other.
Applying a ‘systems theory approach’ on the cognitive psychology conception of knowledge, the impact of the characteristics of existing knowledge on the absorption of new knowledge is described. The developed model is called the ‘Model of Learning Capability’ (MLC). – This is the second model.
It is also necessary to pay attention to the ability to acquire new knowledge; this is described by the ‘Model of Attention’ (MA) – the third model. This model is based on two main factors, namely cognitive and social conditions.
These three models are thus integrated into fourth one, which is called the ‘Model of Learning Ability’ (MLA). For exploration/validation the model is wwwed with the Doctus Knowledge-Based Expert System, which was also the means of comparing the evolved hypotheses with the input from reality, namely observations and thought experiments.
The first insight from the model is a better understanding of the process of ‘knowledge increase’. The model can also be used to support choosing the right person to learn a particular piece of new knowledge, to identify the reason for someone not performing well with regards to learning and/or identifying a possible way of improving the process. Using the logic of the model experts can also be evaluated in the process of knowledge acquisition when building an expert system.
Considering the achieved results some new problems emerge: It is not known what motivates the personal value system during the knowledge absorption; it is not known if the model can be extended to other forms of knowledge increase besides learning; it is not known how the social factors apart from love (i.e. power and money) affect the attention. Some new research ideas also evolved from this investigation, e.g. an attempt to model the knowledge using dimensions of understanding.
