Condicionamiento con estímulos enmascarados: Desarrollo de Efectos de Priming como Evidencia de Aprendizaje Asociativo no Consciente

Resumen

Los argumentos tradicionales de la discusión sobre el papel del procesamiento consciente en el condicionamiento clásico humano se revisan a la luz de los resultados de aprendizaje no consciente obtenidos recientemente en el campo del aprendizaje implícito. Tomando en cuenta las limitaciones de los argumentos teóricos y experimentales que sustentan la «necessary-gate hypothesis» (Dawson y Furedy, 1976), se proponen dos explicaciones alternativas que incluyen la posibilidad de obtener efectos de aprendizaje no consciente. Estas explicaciones se ponen a prueba a través de un estudio experimental de condicionamiento semántico en el que se emplean técnicas de enmascaramiento retroactivo para evitar la percepción consciente del Estímulo Condicionado (EC), del Estímulo Incondicionado (EI) o de ambos, obteniendo claros efectos de aprendizaje asociativo no consciente en los grupos en los que sólo uno de los dos estímulos puede ser procesado conscientemente, cuando este efecto se mide a través de índices indirectos de «priming» automático entre el EC y el El.

Los resultados se discuten en el marco de los papeles que la atención y el procesamiento no consciente pueden jugar en el desarrollo de asociaciones a largo plazo.     

Social dominance theory and the dynamics of intergroup relations: Taking stock and looking forward

This chapter reviews the last 15 years of research inspired by social dominance theory, a general theory of societal group-based inequality. In doing so, we sketch the broad outlines of the theory and discuss some of the controversies surrounding it, such as the “invariance hypothesis” regarding gender differences in social dominance orientation (SDO) and the effect of social context on the expression of SDO. We also discuss the central role of gender in the construction and maintenance of group-based inequality, and review some of the new research inspired by the social dominance perspective. Finally, we identify and discuss some of the most important theoretical questions posed by social dominance theory that are yet to be researched.     

Stressors and Coping Strategies among Early and Middle Adolescent Premier League Academy Soccer Players: Differences According to Age

The purpose of this study was to examine stressors and coping strategies among early (12–14 years) and middle adolescents (15–18 years). Forty male academy soccer players, aged between 12–18 years (M age = 14.22 years), participated in semi-structured interviews, which were inductively and deductively content analyzed. Findings revealed that middle adolescents reported more stressors than early adolescents and that these two groups experienced both common and different stressors. Early adolescents identified making errors, opponents, team performance, and family as salient stressors. Making errors, team performance, coaches, selection, contracts, social evaluation, and playing at a higher level were more prominent among middle adolescents. Middle adolescents reported a greater number and repertoire of coping strategies than early adolescents, and used more problem- and emotion-focused strategies, but fewer avoidance strategies than early adolescents. Based on these findings, it is recommended that applied practitioners working within soccer academies take into account the players' age when providing psychological support.     

Young Tennis Players’ Competitive Task Involvement and Performance: The Role of Goal Orientations,Contextual Motivational Climate,And Coach-Initiated Motivational Climate

The purpose of this study was to examine the role of situational and dispositional factors in contributing to competitive task involvement and performance in young tennis players. One hundred fifty-one adolescent tennis players and their coaches participated in the study. Participants responded to instruments measuring pre-game dispositional goal orientations and perceptions of the motivational climate and post-game task involvement in the competition by assessing concentration, loss of self-consciousness, and autotelic experience, perceptions of coach-initiated motivational climate in competition, and self-evaluation of game performance. In addition, coaches evaluated the players’ performance. Results showed that task involvement was predicted by players’ perceptions of a coach-initiated learning motivational climate in competition. Loss of self-consciousness was predicted by the players’ perceptions of a coach-initiated performance climate in competition. Finally, coaches’ and players’ assessment of performance were predicted by autotelic experience, concentration, and by perception of coach-initiated learning and performance orientation in competition.     

Is the Critical Point for Aperture Crossing Adapted to the Person-Plus-Object System?

When passing through apertures, individuals scale their actions to their shoulder width and rotate their shoulders or avoid apertures that are deemed too small for straight passage. Carrying objects wider than the body produces a person-plus-object system that individuals must account for in order to pass through apertures safely. The present study aimed to determine whether individuals scale their critical point to the widest horizontal dimension (shoulder or object width). Two responses emerged: Fast adapters adapted to the person-plus-object system by maintaining a consistent critical point regardless of whether the object was carried while slow adapters initially increased their critical point (overestimated) before adapting back to their original critical point. The results suggest that individuals can account for increases in body width by scaling actions to the size of the object width but people adapt at different rates.     

An empirical test of Hirschi's control theory of delinquency

Hirschi's control theory of delinquency (1969) contends that lack of attachment to peers, parents, and school leads to a lack of conventional attitudes, which ultimately leads to juvenile delinquency. In order to test this theory, data were collected from questionnaires administered to 724 students in four high schools and three juvenile correctional institutions in the Southwest. Findings from this study indicate that when subjected to path analysis, Hirschi's contention is only supported when delinquent companions is included; that is to say the extent of explained variation in delinquency is greatly enhanced when delinquent companions is introduced as an additional antecedent variable in Hirschi's causal scheme. In addition, the findings are more consistent with a social learning or differential association theory than the original theory proposed by Hirschi in Causes of Delinquency (1969).     

FORCES OF TOMORROW

This article examines the social experience of belonging to the British section of the international Socialist Zionist youth movement, Hashomer Hatzair. The study is based on interviews conducted with 10 former activists across four generations and focuses primarily on the movement in London. It will be argued that Hashomer Hatzair represented a unique alternative youth culture based on a model developed by the movement's founders in the Austro-Hungarian Empire. This model synthesized Robert Baden-Powell's Scouting, the Jugendkultur of the German youth movements, Socialist Zionism and Marxism. Imported to Britain by young German and Austrian refugees from Nazism, this youth culture was reproduced initially in the English countryside, and after the war plugged into the pre-existing politics of Jewish radicalism in London and the general Zionist fervour that anticipated the establishment of Israel. Hashomer Hatzair emphasized autonomy from adult society. By creating autonomous youth spaces, the movement opened a portal for young Jews to shape their own identities. Through a process of politicization and education, the movement's adherents would identify life on Israeli kibbutzim as an ideal future in adulthood. In tandem with the projection of heroic Jewish role models, this process encouraged Hashomer Hatzair's followers to define their Jewishness in secular and existential terms, in opposition both to contemporary consumerist and urbanized capitalism, and to the traditional communal associations of the past.     

What Can Virtual Reality Teach Us About Prosocial Tendencies in Real and Virtual Environments?

As virtual environments (VEs) become increasingly central to people's lives (Terry, 2002 Terry, F. 2002. New Media: An introduction, South Melbourne, , Australia: Oxford University Press.  [Google Scholar]), understanding reactions to VEs may be as important as understanding behavior in the real world (Yee, Bailenson, Urbanek, Chang, & Merget, 2007 Yee, N., Bailenson, J. N., Urbanek, M., Chang, F. and Merget, D. 2007. The unbearable likeness of being digital: The persistence of nonverbal social norms in online virtual environments. The Journal of CyberPsychology and Behavior, 10: 115–121. [Crossref], [PubMed] , [Google Scholar]). Immersive Virtual Environment Technology (IVET), which is now being used in psychological research (Blascovich et al., 2002 Blascovich, J., Loomis, J., Beall, A., Swinth, K., Hoyt, C. and Bailenson, J. 2002. Immersive virtual environment technology as a research tool for social psychology. Psychological Inquiry, 13: 103–125. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), can provide greater experimental control, more precise measurement, ease of replication across participants, and high ecological validity, making it attractive for researchers. It also can create links between researchers who study basic social psychological processes and those who study new media. In two studies we examined people's reactions as they navigated through a virtual world and interacted with virtual people, some of whom needed help. Participants' compassion and tendency to experience personal distress predicted emotional reactions (concern) and proxemic behavior (gaze orientation and degree of interpersonal distance) to a virtual person in need but not to a control person. The results support the use of IVET and proxemic variables to measure compassion unobtrusively and they encourage the use of IVET to advance our understanding of people's behavior in and reactions to virtual worlds and new media.     

The influence of environmental context in interpersonal observation–execution

Cyclical upper-limb movements involuntarily deviate from a primary movement direction when the actor concurrently observes incongruent biological motion. We examined whether environmental context influences such motor interference during interpersonal observation–execution. Participants executed continuous horizontal arm movements while observing congruent horizontal or incongruent curvilinear biological movements with or without the presence of an object positioned as an obstacle or distractor. When participants were observing a curvilinear movement, an object located within the movement space became an obstacle, and, thus, the curvilinear trajectory was essential to reach into horizontal space. When acting as a distractor, or with no object, the curvilinear trajectory was no longer essential. For observing horizontal movements, objects were located at the same relative locations as in the curvilinear movement condition. We found greater involuntary movement deviation when observing curvilinear than horizontal movements. Also, there was an influence of context only when observing horizontal movements, with greater deviation exhibited in the presence of a large obstacle. These findings suggest that the influence of environmental context is underpinned by the (mis-)matching of observed and executed actions as incongruent biological motion is primarily coded via bottom-up sensorimotor processes, whilst the congruent condition incorporates surrounding environmental features to modulate the bottom-up sensorimotor processes.
