Number processing and calculation in Brazilian children aged 7-12 years

Numerical cognition is based on two components - number processing and calculation. Its development is influenced by biological, cognitive, educational, and cultural factors. The objectives of the present study were to: i) assess number processing and calculation in Brazilian children aged 7-12 years from public schools using the Zareki-R (Battery of neuropsychological tests for number processing and calculation in children, Revised; von Aster & Dellatolas, 2006) in order to obtain normative data for Portuguese speakers; ii) identify how environment, age, and gender influences the development of these mathematical skills; iii) investigate the construct validity of the Zareki-R by the contrast with the Arithmetic subtest of WISC-III. The sample included 172 children, both genders, divided in two groups: urban (N = 119) and rural (N = 53) assessed by the Zareki-R. Rural children presented lower scores in one aspect of number processing; children aged 7-8 years demonstrated an inferior global score than older; boys presented a superior performance in both number processing and calculation. Construct validity of Zareki-R was demonstrated by high to moderate correlations with Arithmetic subtest of WISC-III. The Zareki-R therefore is a suitable instrument to assess the development of mathematical skills, which is influenced by factors such as environment, age, and gender.     

Approaching conflict the Ahmadiyya way

The role and incidence of the Ahmadiya community in Israeli society, with its around 2,000 members, is not related to the dimension of the community, its religious activities or its dissemination on the territory. It is related to the strong social and political engagement of the community not only in religious but also in civil society activities where it resides, despite all the difficulties that derive from its disputed role in Islam. The Ahmadiyya community in Haifa constitutes a relevant example of contribution to peaceful and productive coexistence. Haifa itself is characterized by a very interesting social and political climate, by which it is considered a “model” of coexistence in Israel, despite the fact that many contrasts and contradictions persist, such as forms of discrimination and inequalities. The civil society is particularly active, and institutions and NGOs devoted to the Arab-Jewish dialogue are many. Religious and political leaders communicate and participate together in various events, where their openness and mutual respect are intended to symbolize harmony with the intent of this being mirrored by the whole society. The Ahmadiyya Community plays an active role in this evolving process. The author, who has carried out qualitative research in Haifa to film a scientific documentary on the Holiday of Holidays and the validity of the Haifa model of coexistence, applied participant observation in the framework of grounded theory to analyze the role and impact of the Ahmadiyya community in the complex Israeli context, also on the basis of extensive in depth interviews with community members and leaders.     

Perversion: a clinical possibility

Abstract

Clinical work with perverse patients presents numerous difficulties to psychoanalysis, be that due to the characteristics typical of the perverse structure, which is founded on the mechanism of disavowal, or to the inefficiency of neutrality and free association in this kind of practice. A study of existing literature on the subject and a thorough examination of their own clinical findings led the authors to propose a different kind of strategy for dealing with transference that would make clinical work with these patients plausible and indicate options for the paralyzing position that is imposed on the analyst by the perverse patient in order to derange the analytic process. By proposing an alternative for the “semblance subject-supposed-knowledge,” the authors defend the idea that clinical work with perverse patients is possible, resulting in a subject less captive of the phantasmagoric scene.

Drummond S et al. Perversion: eine klinische Möglichkeit

Klinische Arbeit mit perversen Patienten bildet zahlreiche Schwierigkeiten für die Psychoanalyse, sei es wegen der Eigenart der perversen Struktur, welche durch den Mechanismus der Verleugnung begründet wird oder sei es wegen der Ineffektivität der Neutralität und freien Assoziation bei dieser Art von Praxis. Ein Studium der vorhandenen Literatur über das Thema und eine gründliche Überprüfung eigener klinischer Befunde führte die Autoren dazu, eine unterschiedliche Art von Strategie des Umgangs mit Übertragung vorzuschlagen. Das würde klinische Arbeit mit diesen Patienten plausibel machen und auf Optionen für die paralysierende Position hinweisen, die dem Analytiker durch den perversen Patienten aufgebürdet wird, um den analytischen Prozess zu stören. Ein Alternative für das “semblance subject-supposed knowledge” vorschlagend, verteidigen die Autoren die Idee, daß klinische Arbeit mit perversen Patienten möglich ist, mit dem Ergebnis eines Subjekts, welches weniger durch die phantasmagorische Szene gefesselt ist.

Drummond S et al. perversión: una posibilidad clínica.

El trabajo clínico con pacientes perversos presenta numerosas dificultades para el psicoanálisis, puede ser debido a las características típicas de la estructura perversa, fundamentado en le mecanismo de repudio, o debido a la ineficacia de la neutralidad y asociación libre en este tipo de práctica. Un estudio de la literatura existente sobre el tema y un examen completo de los hallazgos clínicos, llevó a los autores a proponer un tipo diferente de estrategia para el manejo de la transferencia, que pudiera hacer posible el trabajo clínico con estos pacientes, también indicar opciones para la situación de paralización que estos pacientes imponen al analista para desorganizar el proceso analítico. Con la proposición de una alternativa para la “semblance-subject-supposed knowledge(apariencia del sujeto-supuesto saber),” el autor defiende la idea de que el trabajo clínico con pacientes perversos es posible, resultando un asunto menos cautivo de la escena fantasmagórica.     

Adopting Employees' Ideas: Moderators of the Idea Generation–Idea Implementation Link

This study examined the possibility that the relationship between the number of ideas an employee generated and the number of those ideas that were adopted by the organization was moderated by the general radicalness of the employee's ideas (i.e., the extent to which the ideas were breakthrough or groundbreaking), the employee's intention to stay, psychological safety, and coworker support. Ninety-three employees generated one or more ideas and raters evaluated the radicalness and implementation of these ideas. Results showed a positive relationship between the number of ideas generated by an employee and the number adopted when the employee's ideas were generally low in radicalness. However, when an employee's ideas were generally high in radicalness, there was a positive relationship between the numbers generated and implemented only when the employee intended to remain a member of the organization or felt psychologically safe at work. The implications of these results for future research and practice are discussed.     

Influence of self‐esteem,locus of control,and organizational climate on psychological empowerment in a sample of Chinese teachers

This study examined the effects of locus of control, self‐esteem, and organizational climate on psychological empowerment in a sample of Chinese teachers. Participants were 1,272 Chinese teachers (460 men and 821 women) residing in six provinces in China. Results indicated that self‐esteem was a positive predictor of psychological empowerment. Several dimensions of organizational climate, namely professional communication, decision‐making, appraisal and recognition, supportive leadership, and professional growth, were also positive predictors of teachers’ psychological empowerment. Locus of control, although related to psychological empowerment, had no predictive effects when other factors related to empowerment were considered.     

Relations among hand preference,craniofacial asymmetry,and ear advantage in young subjects

The relations for hand preference with craniofacial asymmetry and ear advantage, and between craniofacial asymmetry and ear advantage were investigated in young healthy subjects. Ear advantage was recorded as duration of hearing, craniofacial asymmetry by computerized tomography in 44 right-handed and 38 left-handed male and female high school students. Right-handers had a right ear advantage and a larger left craniofacial region, whereas left-handers had a left ear advantage and a larger right craniofacial region. These results are consistent with the speculation that hand preference may be related to craniofacial and consequently aural asymmetries.     

“Weapons effect” revisited: Motor effects of the reception of aversive stimulation and exposure to pictures of firearms

The effect of presenting images of firearms on the speed of clenching of the fist of human subjects simultaneously receiving an aversive stimulation was studied. It was thought that, whereas the classic interpersonal experimental situation confounds the effects of the stimulus presented and several interpersonal processes, speed of fist clenching in a noninterpersonal setting could constitute a valid measure of the subject's readiness to fight. Twenty-four male and 24 female students (ages > 20 and <36 years) were instructed to press with their right hand a device commanding the projection of slides upon reception of an acoustic signal. Speed of clenching of the hand was recorded in the four conditions generated by the combination of two levels of acoustic signal (aversive and nonaversive) and two modalities of slides (firearms or tools). The results show that the reception of aversive sound accelerates fist clenching. Simultaneous presentation of slides of firearms and reception of aversive noise increases the speed of clenching of the fist. The slides' main effect was not significant. More irritable subjects tend to execute this movement faster than their less irritable counterparts, and more emotionally susceptible subjects tend to be slower than less susceptible ones. Male subjects were faster than females. This pattern of results is discussed in relation to the hypothesis formulated by the authors.     

The "anxiety state" and its relation with rat models of memory and habituation.

Rats selected as "anxious", "nonanxious," or normal according to their behavior in an elevated plus maze were submitted to memory tasks and the densities of central benzodiazepine receptors in the amygdala and the hippocampus were studied. Anxious rats exibited better retention scores in the inhibitory avoidance task while nonanxious rats exibited worse retention scores in inhibitory and two-way active avoidance tasks compared to normal rats. No significant differences were detected in the retention scores for habituation to an open field. Nonanxious rats presented a lower benzodiazepine receptor density in the hippocampus but not in the amygdala compared to the other groups. These data suggest that the benzodiazepine receptors are involved in the effect of "anxiety" or emotional states on memory storage processes.     

Amnesia by post-training infusion of glutamate receptor antagonists into the amygdala, hippocampus, and entorhinal cortex.

The blockers of glutamate receptors, aminophosphonovaleric acid (AP5) (5.0 micrograms) and cyano-nitroquinoxaline-dione (CNQX) (0.5 microgram), were infused bilaterally into the amygdala, dorsal hippocampus, or entorhinal cortex of rats through indwelling cannulae 0, 90, 180, or 360 min after step-down inhibitory avoidance training. Animals were tested for retention 24 h after training. In the amygdala or hippocampus, AP5 was amnestic when given 0 min after training and CNQX was amnestic when given 0, 90, or 180 min after training. In the entorhinal cortex, AP5 was amnestic when given 90 or 180 min after training and CNQX had no effect. The results suggest that a phenomenon sensitive first to AP5 and then to CNQX in the amygdala and hippocampus, probably long-term potentiation (LTP), is crucial to post-training memory processing. LTP in these two structures could underlie their role in memory consolidation and could explain the late involvement of the entorhinal cortex in post-training memory processing.     

Processing level and recognition: A search method for inducing alternative encodings of unrelated words

Twenty-four subjects viewed cards containing four words. In synonym orienting, half of the cards contained a synonym pair and half did not; in homophone orienting, half of the displays contained a homophone pair. The remaining two words in each display were used to index retention. During presentation of displays, subjects responded “yes” or “no” to indicate the presence or absence of a matching pair. Following presentation, a recognition test was administered. Half the items were tested early and half were tested late; within each test order, half the items appeared with context cues during testing and half appeared without. Results showed superior recognition (1) following semantic orienting, (2) for items tested early, (3) for items tested with context, and (4) for nonmatch displays requiring exhaustive item comparison. An Orienting by Test Cuing interaction showed that the presence of test cues improved recognition for homophone orienting items only. The interaction may have resulted from the lack of cuetarget associations and the reinstatement of the phonemic orienting set during the test.
