Are the effects of attention on speed judgments genuinely perceptual?

A number of studies in recent years have suggested that exogenous and endogenous attention might enhance the perceived magnitude of various perceptual attributes, such as contrast and motion speed. Those studies have generally used comparative judgments as a measure to assess the point of subjective equality; however, similarity judgments have been proposed as possibly less prone to decision biases (Schneider & Komlos, 2008). In three experiments, using a similarity judgment task, we did not find any evidence of motion speed enhancement by exogenous attention. We suggest that the effect revealed by comparative judgments arises at the decisional, rather than the perceptual, stage.     

CircE: An R implementation of Browne’s circular stochastic process model

In confirmatory analysis of whether data have a circumplex structure, Browne’s (1992) model has played a major role. However, implementation of this model requires a dedicated program, CIRCUM, because the analysis routine is not integrated in any of the most widely used statistical software packages. Hence, data entry and graphical representation of the results require the use of one or more additional programs. We propose a package for the R statistical environment, termed CircE, that can be used to enter or import data, implement Browne’s confirmatory analysis, and graphically represent the results. Using this new software, we put forward a new approach to assess the sustainability of theoretical models when the analysis is carried out at the level of questionnaire items. The CircE package (for either Mac OS X or Windows) and additional files may be downloaded from http://brm.psychonomic-journals.org/content/supplemental.     

Filtering visual onsets via habituation: A context-specific long-term memory of irrelevant stimuli

The fact that we are often immediately attracted by sudden visual onsets provides a clear advantage for our survival. However, how can we resist from being continuously distracted by irrelevant repetitive onsets? Since the seminal work of Sokolov (1963), habituation of the orienting of attention has long been proposed to be a possible filtering mechanism. Here, in two experiments, we provide novel evidence showing that (a) habituation of capture of focused visual attention relies on a stored representation of the distractor onsets in relation to their context, and (b) that once formed such representation endures unchanged for weeks without any further exposure to the distractors. In agreement with the proposal of Wagner (1979) concerning the associative nature of habituation, the results of Experiment 1 suggest that habituation of attentional capture is context specific. Furthermore, the results of Experiment 2 show that to filter visual distractors our cognitive system uses long-lasting memories of the irrelevant information. Although distractor filtering can be implemented via top-down inhibitory control, neural and cognitive mechanisms underlying habituation provide a straightforward explanation for the reduced distraction obtained with training, thus working like an automatic filter that prevents irrelevant recurring stimuli from gaining access to higher stages of analysis.     

Maternal representations during pregnancy and early infant-mother interactions

This paper deals with the influence of maternal representations during pregnancy on the subsequent mother-infant relationship and the infant's style of attachment at 1 year of age. Psychoanalytic thinking, beginning with Freud to the most recent contributions, has considered the great importance of the mental dynamics between parents and children to which empirical research according to Bowlby's theoretical perspective has contributed. The current research project was planned in order to study the intergenerational processes. Starting during pregnancy, the woman was interviewed specifically to study maternal representations of herself as a mother and of the future baby. When the child was 1 year old, the style of attachment was studied during the Ainsworth Strange Situation paradigm and, at the same time, the mother was given the Adult Attachment Interview. Case studies are presented to illustrate, from the clinical point of view, the mental dynamics during pregnancy and the influence on the style of attachment of the baby. The clinical implications are discussed especially in terms of the fantasies in pregnancy and their relevance for the subsequent mother-infant relationship.     

"Brainwashing" Theories in European Parliamentary and Administrative Reports on "Cults" and "Sects"

This study examines the recent rash of official reports done by governmental agencies in Western Europe to guide policy development in those societies. Particular attention is given to reports in France, Belgium, Switzerland, Germany, Sweden, and Italy, and to the changes in such reports that have occurred, perhaps because of the influence of scholarly critiques offered for some of the earlier reports. The reports are divided into "Type I" and "Type II" reports, with the former being thorough-going in their anti-cult orientation, and the latter reports being more moderate in tone, with some attention paid to scholarship on new religions. However, the major thesis of the study is supported, as an examination of both types of reports reveals that they incorporate "brainwashing" and "mind control" imagery imported from the United States, even though such theories have been largely discounted within the United States. Use of such theories leads directly to some questionable policy recommendations, as demonstrated in the reports. Reasons for the spread of "brainwashing" ideas to Europe are discussed.
