Factors Affecting Censorship by Canadian Librarians

This study investigated the risk propensity and self-actualization of public librarians with regard to censorship behavior. A sample of 169 librarians from the province of Ontario responded to a 124-item mail questionnaire that incorporated a number of previously validated instruments, including the Adorno F Scale (Adorno, Frenkel-Brunswick, Levinson, & Sanford, 1950), the Short Index of Self-Actualization (Jones & Crandall, 1986), and the Choice Dilemmas Questionnaire (Kogan & Wallach, 1964). Analyses indicated that the librarians were generally liberal in attitude but conservative in behavior with respect to censorship and book selection. Moreover, they appear to have been averse to taking risks and not selfactualized. These results are discussed in terms of cognitive dissonance theory and risk propensity theory.     

The Analyst’s Private Space: Spontaneity,Ritual, Psychotherapeutic Action,and Self-Care

The contemplation, containing, and linking that circulate within the analyst’s private space are positioned as key to states of psychic equivalence (the melding of psychic reality and material reality) and to sustained states of unknowing, which are held to be necessary for analytic work and fantastic spontaneity. These modes of practice are considered as they relate to rituals that promote the analyst’s self care. An account of a psychotherapy with a 5-year-old electively mute girl is offered to illustrate the work undertaken in the analyst’s private space, as he seeks to build and sustain potential space and the possibilities borne through play.     

The global workspace (GW) theory of consciousness and epilepsy

The global workspace (GW) theory proposes that conscious processing results from coherent neuronal activity between widely distributed brain regions, with fronto-parietal associative cortices as key elements. In this model, transition between conscious and non conscious states are predicted to be caused by abrupt non-linear massive changes of the level of coherence within this distributed neural space. Epileptic seizures offer a unique model to explore the validity of this central hypothesis. Seizures are often characterized by the occurrence of brutal alterations of consciousness (AOC) which are largely negatively impacting patients' lives. Recently, we have shown that these sudden AOC are contemporary to non-linear increases of neural synchrony within distant cortico-cortical and cortico-thalamic networks. We interpreted these results in the light of GW theory, and suggested that excessive synchrony could prevent this distributed network to reach the minimal level of differentiation and complexity necessary to the coding of conscious representations. These observations both confirm some predictions of the GW model, and further specify the physiological window of neural coherence (minimum and maximum) associated with conscious processing.     

Effect of tactical initiative on predicting passing shots in tennis

This study aimed to demonstrate that one of the main sources of information that tennis players use to anticipate their opponents' strokes is prior knowledge of the upcoming events likely to develop when the player has the opportunity to impose his or her playing intent. Seventeen experienced male players were faced with simulated on‐court situations with three different delivery conditions such that their tactical initiative was high, moderate or weak (reflecting the possibilities of controlling rallies). Each situation finished with a passing shot from the opponent that the participant had to intercept with a volley stroke in the absence of visual information (vision occluded before the opponent's stroke). Analysis of directional responses showed that the participants were more accurate if they were in firm control of the rallies (high level of tactical initiative). Forecasts were also found to be more accurate for down‐the‐line backhand shots. These findings increase our understanding of anticipation in tennis. Copyright © 2005 John Wiley & Sons, Ltd.     

Can business and economics students perform elementary arithmetic?

Business and economics majors (N=146) were tested on the D'Amore Test of Elementary Arithmetic, which employs third-grade test items from 1932. Only 40% of the subjects passed the test by answering 10 out of 10 items correctly. Self-predicted scores were a good predictor of actual scores, but performance was not associated with demographic variables, grades in calculus courses, liking for science or computers, or mathematics anxiety. Scores decreased over the subjects' initial years on campus. The hardest test item, with an error rate of 23%, required the subject to evaluate (36 x 7) + (33 x 7). The results are similar to those of Standing in 2006, despite methodological changes intended to maximize performance.     

Conscious, preconscious, and subliminal processing: a testable taxonomy

Of the many brain events evoked by a visual stimulus, which are specifically associated with conscious perception, and which merely reflect non-conscious processing? Several recent neuroimaging studies have contrasted conscious and non-conscious visual processing, but their results appear inconsistent. Some support a correlation of conscious perception with early occipital events, others with late parieto-frontal activity. Here we attempt to make sense of these dissenting results. On the basis of the global neuronal workspace hypothesis, we propose a taxonomy that distinguishes between vigilance and access to conscious report, as well as between subliminal, preconscious and conscious processing. We suggest that these distinctions map onto different neural mechanisms, and that conscious perception is systematically associated with surges of parieto-frontal activity causing top-down amplification.     

Judging the urgency of nonvocal auditory warning signals: perceptual and cognitive processes

Previous research has identified acoustic properties modulating the perceived urgency of alarms. The authors conducted 3 experiments using a multidimensional approach in which participants made acoustic dissimilarity judgments and urgency dissimilarity judgments for pairs of sequences. Experiment 1 confirmed the validity of acoustic parameters in urgency perception of experimental alarms. Experiment 2 confirmed the role of these acoustic parameters with real alarms but suggested the importance of additional factors. Experiment 3 compared the relative degrees of urgency of alarms from Experiments 1 and 2, highlighting the role of both sequence structure and associated mental representation. The authors conclude that the design of alarms should not be based exclusively on acoustic factors but should also take into consideration the acquisition of an appropriate mental representation.
