Methods for studying unconscious learning

2005

One has to face numerous difficulties when trying to establish a dissociation between conscious and unconscious knowledge. In this paper, we review several of these problems as well as the different methodological solutions that have been proposed to address them. We suggest that each of the different methodological solutions offered refers to a different operational definition of consciousness, and present empirical examples of sequence learning studies in which these different procedures were applied to differentiate between implicit and explicit knowledge acquisition. We also show how the use of a sensitive behavioral method, the process dissociation procedure, confers a distinctive adva…

The hippocampus and remote autobiographical memory.

2005

In Newsdesk (August, 2005),1 new evidence for the neuroanatomy of remote memory was reported. On the basis of the findings of the US team lead by Larry Squire,2 remote autobiographical memory was suggested to be independent of the medial temporal lobe but dependent on the neocortex. By contrast with previous hypotheses, this new proposal predicts that after damage to the medial temporal lobe only recent autobiographical memories should be impaired in neurological patients, whereas loss of both recent and old autobiographical memories implies additional damage in the neocortex. However, there is evidence not included in the Newsdesk article, that is problematic for this new prediction. Two p…

Introducing implicit learning: from the laboratory to the real life

2010

The dissociation between implicit and explicit cognition has a long history in psychology. As early as 1920, Clark Hull (25) investigated the learning of Chinese ideographs and identified the process of concept formation by abstraction of common elements, a process that occurs without explicit knowledge from the subjects of these regularities. Perceptual learning is another example of those processes that take place largely in the absence of awareness of the rules that govern the stimulations of the environment. Helmholtz (24) was one of the first to refer to implicit inference made by the perceptual system and to perceptual learning. Some years later, the distinction between implicit and e…

Concentrated Solar Power: Ontologies for Solar Radiation Modeling and Forecasting

2014

This chapter considers the possibility of formally representing implicit and explicit knowledge of solar radiation modeling and forecasting by means of ontologies, with particular reference to the implications of concentrated solar power. The various applications discussed in the literature include various methods, such as spectral, parametric and empirical models, artificial neural networks and fuzzy logic approaches, as well as satellite and ground based imaging techniques. We want to use the principles of semantic technologies and formal ontologies, to represent knowledge in solar radiation models. The purpose is to capture the semantics of information and realize a system for sharing an…

The advantage of errorless learning for the acquisition of new concepts' labels in alcoholics

2009

BackgroundPrevious findings revealed that the acquisition of new semantic concepts' labels was impaired in uncomplicated alcoholic patients. The use of errorless learning may therefore allow them to improve learning performance. However, the flexibility of the new knowledge and the memory processes involved in errorless learning remain unclear.MethodNew concepts' labels acquisition was examined in 15 alcoholic patients and 15 control participants in an errorless learning condition compared with 19 alcoholic patients and 19 control subjects in a trial-and-error learning condition. The flexibility of the new information was evaluated using different photographs from those used in the learning…

Chiral symmetry breaking condensates from baryonic sum rules

1984

We analyse baryonic sum rules in order to determine chiral symmetry breaking condensates. We especially investigate the influence of the choice of the interpolating field and of the factorization hypothesis for the four quark condensate. Our results are consistent with those obtained from pseudoscalar sum rules and PCAC.

The emergence of explicit knowledge during the early phase of learning in sequential reaction time tasks

1997

Five experiments investigated the formation of explicit knowledge of a repeating sequence in a sequential reaction time task. Reliable explicit knowledge was obtained even though various conditions prevented the selective improvement of RTs (Exps. 1–4). This knowledge emerged early during training. Participants were able to recognize segments of the sequence (Exps. 3 and 4) or correctly assess the probabilities of transition of the target between successive locations (Exp. 5) after only two blocks of training trials. These findings rule out an interpretation of sequence learning that posits that explicit knowledge emerges from implicit knowledge during the course of training. Although these…

Different facets of attitudes towards having children: The Procreation Attitude Scale (PrAttS)

2020

The attitudes towards children are more complex than simple positive/negative distinctions. In the present study, we sought in two studies (N = 445) to provide a tool to explore different facets of attitudes towards babies and procreation by developing and validating a questionnaire regarding attitudes towards procreation. Study 1 was conducted to develop an English language scale tapping into adults’ attitudes toward having offspring. A larger number of statements were formulated that expressed an emotional value and motivational attitudes towards having babies. The sample consisted of n = 157 participants. Participants’ responses were subjected to a preliminary principal components analys…
