The spatial constraint in intersensory pairing: no role in temporal ventriloquism

A sound presented in temporal proximity to a light can alter the perceived temporal occurrence of that light (temporal ventriloquism). The authors explored whether spatial discordance between the sound and light affects this phenomenon. Participants made temporal order judgments about which of 2 lights appeared first, while they heard sounds before the 1st and after the 2nd light. Sensitivity was higher (i.e., a lower just noticeable difference) when the sound-light interval was approximately 100 ms rather than approximately 0 ms. This temporal ventriloquist effect was unaffected by whether sounds came from the same or a different position as the lights, whether the sounds were static or moved, or whether they came from the same or opposite sides of fixation. Yet, discordant sounds interfered with speeded visual discrimination. These results challenge the view that intersensory interactions in general require spatial correspondence between the stimuli.     

Rehearsal in serial memory for visual-spatial information: Evidence from eye movements

It is well established that rote rehearsal plays a key role in serial memory for lists of verbal items. Although a great deal of research has informed us about the nature of verbal rehearsal, much less attention has been devoted to rehearsal in serial memory for visual-spatial information. By using the dot task—a visual-spatial analogue of the classical verbal serial recall task—with delayed recall, performance and eyetracking data were recorded in order to establish whether visual-spatial rehearsal could be evidenced by eye movement. The use of eye movement as a form of rehearsal is detectable (Experiment 1), and it seems to contribute to serial memory performance over and above rehearsal based on shifts of spatial attention (Experiments 1 and 2).     

Can we fight stigma with science? The effect of aetiological framing on attitudes towards anorexia nervosa and the impact on volitional stigma

The present study experimentally investigated the way in which exposure to various aetiological explanations of anorexia nervosa (AN) differentially affected stigmatisation and behavioural intention outcomes. University students (N = 161) were randomly assigned to read one of four aetiological vignettes presenting the causes of AN as biological/genetic, socio‐cultural, environmental, or multifactorial. Results indicate that those who received a socio‐cultural explanation made stronger socio‐cultural causal attributions, fewer biological/genetic causal attributions, and were significantly less willing to sign a health insurance petition for AN. Unexpectedly, the multifactorial group considered individuals with AN as more responsible and blameworthy for their condition. Overall, findings were comparative with previous research and partially support the propositions of attribution theory. Results also suggest that by conceptualising the aetiology of AN as biological or genetic, or at least increasing one's knowledge of these contributing factors, it may be possible to decrease the level of blame‐based stigma associated with AN.     

Immediate serial recall of words and nonwords: Tests of the retrieval-based hypothesis

In two experiments, the immediate serial recall of lists of words or nonwords was investigated under quiet and articulatory suppression conditions. The results showed better item recall for words but better order recall for nonwords, as measured with proportion of order errors per item recalled. Articulatory suppression hindered the recall of item information for both types of lists and of order information for words. These results are interpreted in light of a retrieval account in which degraded phonological traces must undergo a reconstruction process calling on long-term knowledge of the tobe-remembered items. The minimal long-term representations for nonwords are thought to be responsible for their lower item recall and their better order recall. Under suppression, phonological representations are thought to be minimal, producing trace interpretation problems responsible for the greater number of item and order errors, relative to quiet conditions. The very low performance for nonwords under suppression is attributed to the combination of degraded phonological information and minimal long-term knowledge.     

A transgenerational conceptualization of psychosomatic distress during pregnancy: Implications for infant mental health

A conceptualization of psychosomatic distress during pregnancy is suggested, stemming from a developmental psychopathology framework and based on contributions from the psychosomatic and attachment literature. A link is suggested between psychosomatic distress during pregnancy, patterns of representational activity, and transgenerational risks of relationship disturbances. Developmental transformations during pregnancy are reviewed, with an emphasis on the vicissitudes of integrating internalized relationships with a person's family of origin. Psychosomatic theory is used to generate hypotheses about the representational activity of mothers who experience psychosomatic distress during pregnancy. Attachment theory is used to discuss the link between maternal representational activity and the transgenerational transmission of relationship patterns. As an example of psychosomatic distress during pregnancy, relevant literature on severe nausea and vomiting during pregnancy is reviewed, and clinical vignettes are presented to illustrate how this condition may sometimes be a forerunner of mother-infant difficulties.     

Interference in Visual Working Memory

This paper uses the theoretical distinction that has recently developed between the passive visual store and the active spatial rehearsal mechanism of the visuo-spatial component of working memory (VSSP). It examines the circumstances under which visual fields gain functional access to the passive visual store and seeks to cast light on the circumstances under which irrelevant visual fields interfere with concurrent visual processing. Experiment 1 contrasts a dynamic visual noise field with a static noise field and shows that the static field, in contrast to the dynamic noise field, causes no interference when presented concurrently with a visual task. Experiment 2 investigates the reason for this contrast and concludes that the static field is susceptible to decay and so fails to cause interference. Experiment 3 investigates further the circumstances under which dynamic visual noise causes interference and shows that manipulation of the number of changes within the noise field is also of importance in causing interference. The results allow further consideration of the characteristics of the VSSP.

NÉCESSITÉ ET SIGNIFICATION DES RECHERCHES COMPARATIVES EN PSYCHOLOGIE GÉNÉTIQUE

Need and meaning of comparative studies in genetic psychology. — The comparative studies in the field of genetic psychology are indispensable for Psychology in general and also for Sociology, because only such studies allow us to separate the effects of biological or mental factors from those of social and cultural influences on the formation and the socialization of individuals. Relevant to this discussion is the well-known issue between culturalistic psychoanalysts like Fromm, Horney, etc., and classical freudian psychoanalysts who reduce the whole individual development to an endogenous evolution of « instinct ». In the field of cognitive functions to which this paper is devoted, at least four kinds of various factors must be distinguished, the respective influences of which can be separated through comparative studies : I. Biological factors depending on the “epigenetic” system (maturation of nervous system, etc.). These factors probably explain the sequential aspects (constant and necessary order) of the stages in the development of operative intelligence. However, if only these factors were acting, the stages would not only appear in a sequence, but at the same ages, whereas in fact, the ages where a stage appears differ from one environment to another. 2. Equilibration or autoregulation factors, determining behavior and thought in their various specific activities. They correspond to the sequential forms in general coordination of the actions of individuals as interacting with their physical environment; such intervening regulations are probably at the origin of the mental operations themselves, especially logical - mathematical operations. 3. General socialization factors, which are identical for all societies : cooperations - discussions - oppositions - exchanges, etc., between children or between adults or between adults and children. These factors 3 are closely related with the factors 2, because the general coordination of actions concerns inter-individual as so as intra-individual actions. 4. Factors related to educational and cultural transmission, which differ from one society to another; they are those we usually have in mind when we say briefly “social factors”. To discuss the influence of these four factors, Mohseni's study on Teheran school children and illiterate rural children is given as an example. Three results were obtained : (1) For “conservation” tasks, the same stages of intellectual development are observed for urban and rural children, in Iran as well as in Europe. (2) For these same tasks, a systematic delay of two to three years is observed among rural children with respect to Teheran children. (3) For performance tests (i.e. Porteus, Goodenough, etc.) there is a delay of four and primarily five years. These data seem to show that there is some sequential order of the stages which depends partially on the factors I. But, the ages for each stage are not constant, showing the factors 2 and 3 are intervening in a probably inseparable way. On the other hand, the difference between the actual operative results and the performance tests seems to indicate that a distinction might be made between the factors of general coordination (factors 2 and 3) and the educational transmissions (factors 4). About these last factors, the three and four year delays observed by Canadian psychologists working in Martinique with school children (French curriculum) in operative tasks (like conservations) seem to indicate that the general operations depend less on school than on the activities themselves of children or in general on the adult stimulations in the environment. We must pay special attention to the problems raised by language. In some precise and systematic experiments in Geneva, Sinclair shows children on the “preoperative” level (i.e. with no conservation…) do not spontaneously use the same language as operative children : the former use chiefly “scale” words (“much” or “many”, “little” or “few”, “large”, “small”) and the latter use chiefly “vector” words (“more”, “less”). If the younger subjects are submitted to a verbal training, they do learn to use the older children's language, but it only results in very little operative improvement (about one case out of 10 subjects on the average). Therefore, replicating the same experiments in countries speaking different languages would be very interesting. For instance, in the Turkish language, there is only one “vector” word, i.e. “again”; so that the Turk says “again much, again many” to say “more”. Then, the question is to know whether a change will be observed for the stages of logical-mathematical operations or whether these operations will be found everywhere with their identical common background; it seems that this last conclusion has already been observed in Aden (Hyde), Hong Kong (Goodnow), South Africa (Price-Williams). In conclusion, the kind of psychology we develop in our social environments, remains conjectural as long as comparative extensive and systematical research is not available; a great effort is still to be made in this direction.     

Mathematical engineering and mathematical change 1

In this paper, I introduce and examine the notion of “mathematical engineering” and its impact on mathematical change. Mathematical engineering is an important part of contemporary mathematics and it roughly consists of the “construction” and development of various machines, probes and instruments used in numerous mathematical fields. As an example of such constructions, I briefly present the basic steps and properties of homology theory. I then try to show that this aspect of contemporary mathematics has important consequences on our conception of mathematical knowledge, in particular mathematical growth.
