Physical Oracles: The Turing Machine and the Wheatstone Bridge

Earlier, we have studied computations possible by physical systems and by algorithms combined with physical systems. In particular, we have analysed the idea of using an experiment as an oracle to an abstract computational device, such as the Turing machine. The theory of composite machines of this kind can be used to understand (a) a Turing machine receiving extra computational power from a physical process, or (b) an experimenter modelled as a Turing machine performing a test of a known physical theory T. Our earlier work was based upon experiments in Newtonian mechanics. Here we extend the scope of the theory of experimental oracles beyond Newtonian mechanics to electrical theory. First, we specify an experiment that measures resistance using a Wheatstone bridge and start to classify the computational power of this experimental oracle using non-uniform complexity classes. Secondly, we show that modelling an experimenter and experimental procedure algorithmically imposes a limit on our ability to measure resistance by the Wheatstone bridge. The connection between the algorithm and physical test is mediated by a protocol controlling each query, especially the physical time taken by the experimenter. In our studies we find that physical experiments have an exponential time protocol; this we formulate as a general conjecture. Our theory proposes that measurability in Physics is subject to laws which are co-lateral effects of the limits of computability and computational complexity.     

Corrective Emotional Experience Remembered

The paper examines on the one hand the influence of the Berlin Institute in the 1920s on Franz Alexander's training and on his later work, as it was a workshop aiming to test the possibilities of a large utilization of psychoanalytic therapy in an institutional framework. On the other hand, the spirit of experimentation of Sándor Ferenczi and the endeavor to enhance the effectiveness and efficiency of psychoanalysis by the use of countertransference and emotional exchange also became important for Alexander. A glimpse of recent researches on Freud's timetable gives background information with possible comparisons between Freud's technique and that of Alexander.     

Development and validation of a Spanish version of the Athletic Coping Skills Inventory, ACSI-28

This study involved the translation, cultural adaptation and validation of the Athletic Coping Skills Inventory (ACSI-28) for a Spanish-speaking sport environment. The sample was made up of 1,253 Spanish athletes, 967 males and 286 females. Confirmatory factor analysis (CFA) showed that the 7-factor structure found in the English version was replicated in the Spanish translation in both males and females. Likewise, the reliability coefficients were similar to those of the English version, with values exceeding .80 for the total score. Several of the subscales correlated positively with sports experience and performance level. The Spanish version of the ACSI-28 thus maintains the factor structure of the original and exhibits similar psychometric properties. Consequently, it can reliably be applied to Spanish-speaking athletes for research and evaluation purposes.     

The clinical revolution of the ‘wise baby’

In an historical context focused on a close examination of the complex relationship between Freud and Ferenczi, the author shows Ferenczi's contribution to the evolution of psychoanalysis. He describes how his ideas and his therapeutic sensitivity anticipated modern clinical thought (for example, Winnicott and Bion), especially the understanding of borderline and narcissistic pathology. The paper considers the following topics: transference and countertransference; early affectivity; the different psychic trauma; phenomena connected with dissociation; the healing factor of the analysis.     

The Use of Priority Information in Performance Feedback

To provide the most value to an organization, individuals must focus efforts on those outputs that have maximum value to the organization. However, the realities of the workplace are that information about performance and how individuals can add value to an organization is complex; that is, determining which activities to focus on is a fairly complex task because such information is nonlinear, whereby the importance of a certain activity may change depending on the level of performance at any given time. This article empirically examines whether providing complex, nonlinear feedback that reflects the complexities of the real world will result in a change in work outputs that reflect these nonlinearities. This article assesses whether employees can and do use complex feedback that reflects the complexity of the real world in the intended ways. In addition, this article examines whether individuals use feedback that includes priority information beyond feedback that reports on simple relative importance. Data were analyzed from 9 work units for time periods averaging a little over a year. Results indicate that, as predicted, when individuals have access to both complex, nonlinear priority information and simple, linear relative importance information, individuals can and do use the complex data in the intended way.     

La percepción de la conducta agresiva: Un estudio taxonómico de las diferencias inter e intraculturales

Resumen

El presente artículo tiene corno principal objetivo ser una alternativa a las tradicionales clasificaciones teóricas de la agresión e, incluso, a los estudios taxonómicos empíricos más recientes. Usar estímulos no representativos, ofrecer indicios sobre las dimensiones de juicios preseleccionados, etc. son algunos de los inconvenientes que no permiten considerar a estas dimensiones perceptuales de la agresión como fiables. En este trabajo se pretenden superar estas y otras críticas con el fin de proporcionar las verdaderas dimensiones que subyacen a la percepción social de los episodios agresivos cotidianos. El Escalamiento Multidimensional (Modelo IÑDSCAL) fue seleccionado como el análisis más apropiado para proponer una taxonomía empírica adecuada y comprobar hasta qué punto una misma taxonomía es compartida por diferentes subculturas (Universitaria y Reclusa). El análisis de los datos nos permitió concluir acerca de la existencia de un dominio psicológico en 4 dimensiones para percibir un conjunto de estímulos agresivos, de la existencia de ciertas diferencias entre ambas submuestras y, por último, de la homogeneidad existente dentro de una misma muestra, independientemente de algunas variables de personalidad previamente seleccionadas.     

Values and Antisocial Behavior Among Spanish Adolescents

A number of studies have indicated that delinquent adolescents have characteristic value systems. However, most of these studies have adopted a “known-groups” design—that is, they have compared institutionalized delinquents and non-institutionalized adolescents, assuming those adolescents to be non-delinquent. Designs of this type do not distinguish effectively between the statistical effects of delinquency and of institutionalization. In this study, the authors investigated relationships between values and self-reported antisocial behavior in three adolescent groups: 435 school-attending boys, 529 school-attending girls, and 95 delinquent boys in juvenile rehabilitation centers or prisons. The results indicate that antisocial behavior is associated with hedonistic values and a lack of interest in conventional values and social values. These relationships cannot be explained by the institutionalization effects.     

Full naming with bi-dimensional abstract stimuli in six-year-old children

The aim of this study was to evaluate a procedure to reveal the emergence of full naming in typically developing children. In Experiment 1, five 6-year-old children (a) learned tacts of pictures and the emergence of the selection of these pictures upon hearing their names was tested; and (b) the selection of other pictures was taught and the emergence of the tacts was tested. All children showed the emergence of picture selection and 3 children showed the emergence of the tacts. In Experiment 2a, the children's correct repetition of the names of 3 pictures was verified first, then the experimenter presented the pictures with their names without requiring any behavior other than attending. Finally, the emergence of picture selection and the tacts was tested. Experiment 2b replicated Experiment 2a with words that were easier to pronounce. Picture selection and the tacts emerged; this performance documented full naming for the first time with typically developing children. These procedures can be used to induce naming capacity in children who lack it; hence, they can be applied to teach children with learning delays.
