Counselling glue sniffers and solvent abusers

This paper reviews the historical background and the current situation with reference to glue sniffing and volatile substance abuse practices by school children and young people. Various approaches to counselling are described and discussed with a view to encouraging the development of more caring services to treat those chronic cases who are urgently in need of help. It is emphasised that any response to volatile substance abuse should be directed more towards the person than the condition, which may be symptomatic of a whole range of personal problems requiring guidance and counselling.     

Processing of proprioceptive information in Parkinson's disease patients

The present study is concerned with a comparison of Parkinson's disease patients and normal subjects on a number of simple and choice reaction time tasks in accordance with Sternberg's interactive procedures. The results indicated that the motor disorder in Parkinson's disease was at the level of output processing and related to the inability of central mechanisms to select and organize responses. Further, the results suggested that patients had difficulty in formulating complex plans or programmes for action.     

Cohérence et vérité. Le rôle des modalisateurs épistémiques dans l'établissement de la vérité propositionnelle

We proposed that the condition truth be understood as the result of a decision about the values taken on by the conditions for fulfilment of the act of referencing in a mental model. Our cognitive model of propositional truth attribution (Baudet, Jhean-Larose, & Legros, 1994) is built on the assumption that the truth value of a proposition is determined by the ability of that proposition to fit into the theory of the field to which it refers. The experimental results proved to be compatible with the proposed model. They validate the first phase of our model: the selection of incoherent subset of truth candidates. This selection is operated thanks to the attribution of plausibility value. This value is determined by explicit index of the pledging of the sender as for the truth of proposals contained in the text sentences. According to these results, the epistemic modalisers of the type “I know” and the type “I believe”, commit the transmitter in different ways as to the truth of propositions. They determine degrees of plausibility and relative coherence between assertions and the mental model in operation. The main function of the enunciation operators such as “I know” in a text, is:

The Place and Role of Psychology in Cognitive Science: An International Survey

This paper reports the results of an international survey on the place and role of psychology in cognitive science (CS). The respondents were psychological societies from 31 countries illustrating a variety of situations, from countries where psychology has been established as a science for a long time to countries where it has been established more recently and is still developing. The paper reviews topics covered by the CS approach, as well as research operations and initiatives taken in this domain. The analysis of responses reflects the belief that psychology, in general, has a central role in CS. This is based on epistemological considerations, as well as on the recognition of the methodological expertise of psychology for collecting and analyzing empirical data. Psychology is reported to have a unique integrative capacity and to take care to maintain the place of the human being at the centre of CS. Limitations and obstacles to the development of pluridisciplinary research on cognition are also reported, and information is provided on the training programmes in CS and the institutions that support research in this domain.     

Memory of imagined actions: Imagining oneself or another person

Summary In two experiments, three modes of action encoding were compared: overt enactment, self-imagination, and imagination of another person performing the actions. Overt enactment and imagining self-performance of an action are mainly assumed to involve motor-kinesthetic representations, whereas imagining another person is thought to place more demands on the visual representational system. Previous paired-associate learning data on memory of action verbs showed that motor-kinesthetic imagery hinders pair integration, but that pair integration is facilitated by visual imagery. The comparison of free and cued recall of actions learned from lists of concrete nouns supports the assumption that the representational properties of overt enactment and self-imagination differ from those involved in the imagining of another person.     

Analogy as relational priming: a developmental and computational perspective on the origins of a complex cognitive skill

The development of analogical reasoning has traditionally been understood in terms of theories of adult competence. This approach emphasizes structured representations and structure mapping. In contrast, we argue that by taking a developmental perspective, analogical reasoning can be viewed as the product of a substantially different cognitive ability - relational priming. To illustrate this, we present a computational (here connectionist) account where analogy arises gradually as a by-product of pattern completion in a recurrent network. Initial exposure to a situation primes a relation that can then be applied to a novel situation to make an analogy. Relations are represented as transformations between states. The network exhibits behaviors consistent with a broad range of key phenomena from the developmental literature, lending support to the appropriateness of this approach (using low-level cognitive mechanisms) for investigating a domain that has normally been the preserve of high-level models. Furthermore, we present an additional simulation that integrates the relational priming mechanism with deliberative controlled use of inhibition to demonstrate how the framework can be extended to complex analogical reasoning, such as the data from explicit mapping studies in the literature on adults. This account highlights how taking a developmental perspective constrains the theory construction and cognitive modeling processes in a way that differs substantially from that based purely on adult studies, and illustrates how a putative complex cognitive skill can emerge out of a simple mechanism.     

The word grouping hypothesis and eye movements during reading

The distribution of landing positions and durations of first fixations in a region containing a noun preceded by either an article (e.g., the soldiers) or a high-frequency 3-letter word (e.g., all soldiers) were compared. Although there were fewer first fixations on the blank space between the high-frequency 3-letter word and the noun than on the surrounding letters (and the fixations on the blank space were shorter), this pattern did not occur when the noun was preceded by an article. R. Radach (1996) inferred from a similar experiment that did not manipulate the type of short word that 2 words could be processed as a perceptual unit during reading when the first word is a short word. As this different pattern of fixations is restricted to article-noun pairs, it indicates that word grouping does not occur purely on the basis of word length during reading; moreover, as the authors demonstrate, one can explain the observed patterns in both conditions more parsimoniously without adopting a word-grouping mechanism in eye movement control during reading.
