These primitives are explicitly derived within the context of a complete visual system.

The hypothesis is put forward that the human visual motion detection system is limited to considering only one visual object at a time, this visual object being however allowed to embrace any part of the observed scene, whether the chosen part consists of many physical objects, or only one, or only a small part of one.

In fact, this model predicts phenomena produced by motion of any gray shaded patterns relative to the eyes (termed "Motion Blur Illusions"). Results of a computer simulation of the model are presented. A novel instance of the proposed class of illusions, which can be readily experienced by the reader is introduced to illustrate the generality of the model.

The relationship between these factors and eye velocity (V e ) has been formally specified as V e =k P s f s [deg s -1 ], where it has been argued that the value of k, which defines the rate limit for eye velocity, is normally 1, or exceptionally 2 or 3. However, theoretically the limitations on the maximum value for k are the maximum optimal pursuit speed for eye tracking (V max ) and the minimum values which P s and f s can assume while preserving target discrimination, and since the values for V max are known to lie well beyond 20 deg/s and those for P s and f s well below 0.3 deg and 10 Hz respectively, it should be possible to demonstrate empirically that k can assume integer values considerably larger than the indicated maximum of 3. To test this prediction, three subjects performed seven series of five EOG-monitored trials producing sigma-pursuit, with values of k ranging from 1 to 7. All subjects evidenced smooth pursuit eye tracking for every condition and reported experiencing sigma-type apparent motion in 95% of the trials. The results confirm theoretical expectations and unequivocally demonstrate that sigma tracking can be readily effected under conditions where k significantly exceeds the maximal values previously reported, in conformity with theory.

Giacosa Je tente ici de faire valoir le point de vue selon lequel il demeure pertinent, contrairement à ce que la rectitude politique me semble vouloir prêcher, de s'interroger sur les possibles différences entre les hommes et les femmes en ce qui a trait aux aspects de la dynamique psychique que la problématique pédagogique interpelle. Je fais d'abord remarquer que je n'ai pu trouver aucune « théorie scientifique » s'y rapportant dans les sciences humaines prétendant s'y intéresser. Je propose ensuite une amorce de traitement théorique de la problématique, que je pousse jusqu'à l'opérationnalisation, puis à un premier test empirique, qui m'apparaît concluant quant à l'intérêt de poursuivre la lancée. En conclusion, je lance quelques pistes de réflexions sur les implications de ma théorie relatives à la pratique pédagogique.

An example that can be readily experienced by the reader is provided. The term amblygram is proposed to refer to this class of images.

The experimental paradigm was based on a new theory of masculinity and femininity developed by Lamontagne (2010), proposing one respective factor per dimension. This study (1) re-evaluates Lamontagne's initial findings using a modified qualitative tool and a new quantitative measure: The Questionnaire of Objectality and Subjectality (QOS; Gabbay, 2010); (2) verifies the QOS' psychometric properties; (3) evaluates inter-sex differences on proposed factors; and (4) examines complementarity of femininity and masculinity between romantic partners. The modified qualitative tool, the Bem Sex Role Inventory (BSRI; , and the QOS were administered to 134 individuals. Findings supported a theoretically coherent factor structure. Subscales demonstrated good reliability and the expected correlations with the BSRI. Gender differences were qualitatively and quantitatively significant. Within couples, partners' relative femininity and masculinity were complementary.

Unfortunately, social science students rarely develop an intuitive understanding of the mean and rely on the formula to describe or define it. According to constructivist pedagogy, educators that have access to a variety of conceptualizations of a particular concept are better equipped to teach that concept in a meaningful way. With this in mind, this article outlines five conceptualizations of the arithmetic mean and discusses how each conceptualization can be presented in the classroom. Educators can use these conceptualizations in order to foster insight into the mean.
