Dependency in consumer media relations: an application to the case of teleshopping

• This paper analyses the teleshopping issue in terms of the Media Dependency Theory. The objective is to verify whether dependency relations between television shoppers and the television medium and television shopping are key variables to explain watching and buying behaviour. A model is proposed that integrates the dependency‐viewing‐purchase relation, tested on a sample of Spanish television shoppers. The results of the study confirm the direct relationship between the antecedents of dependency, dependency and future intentions of behaviour.

Anxiolytic-like activity of SB-205384 in the elevated plus-maze test in mice

Recent studies point to a major role for alpha2-containing GABA-A receptors in modulating anxiety. However, the possible implication of GABA-A receptors containing the alpha3 subunit on anxiety is less known. The aim of this study was to examine the effects of SB-205384 (0.5-4 mg/kg, i.p.), an alpha3 subunit positive modulator of GABA-A receptor, on anxiety tested in the elevated plus-maze in male mice, using classical and ethological parameters. Mice treated with SB-205384 showed an increase in the frequency of entries and the time spent in open arms, as well as a reduction in the time spent in closed arms, as compared with the control group. A notable increase of "head-dipping" unprotected and a reduction of "stretched-attend posture" protected was also evident. These findings indicate that SB-205384 exhibits an anxiolytic-like profile in the elevated plus-maze test, suggesting that GABA-A receptors which contain the alpha3 subunit might be involved in regulation of anxiety.     

Cortical memory mechanisms and language origins

We have previously proposed that cortical auditory-vocal networks of the monkey brain can be partly homologized with language networks that participate in the phonological loop. In this paper, we suggest that other linguistic phenomena like semantic and syntactic processing also rely on the activation of transient memory networks, which can be compared to active memory networks in the primate. Consequently, short-term cortical memory ensembles that participate in language processing can be phylogenetically tracked to more simple networks present in the primate brain, which became increasingly complex in hominid evolution. This perspective is discussed in the context of two current interpretations of language origins, the "mirror-system hypothesis" and generativist grammar.     

Regression toward the mean or heuristic processing in detecting deception? Reply to Elaad (2010)

Masip, et al. (2009) conducted a study in which observers had to make truth-lie judgments at the beginning, middle, or end of a series of videotaped statements. They found a decline in truth judgments over time and explained this finding in terms of information processing mode. Recently, Elaad (2010) challenged this explanation and contended that the decline could be a result of regression toward the mean. In the present paper, it is argued that because Masip, et al. took multiple Moment 1 judgments over time and then averaged across judgments, regression toward the mean was extremely unlikely. Furthermore, the decrease in truth judgments was found under several separate conditions; this cannot be explained by random fluctuations alone. Finally, Masip, et al.'s data were re-analyzed adjusting for the effects of regression toward the mean. The outcomes of these analyses were the same as those reported in the original article.     

Psicología de la violación

Resumen

Este artículo constituye una revisión de la literatura psicológica referida a la violación. En la primera parte nos ocupamos del agresor sexual, enfatizando la naturaleza fundamentalmente agresiva de la violación, y poniendo de manifiesto la necesidad de superar la perspectiva tipológica. La segunda parte trata de la víctima, poniéndose de relieve los impactos de la agresión recibida y las difíciles circunstancias por las que pasa la mujer que ha denunciado el hecho en el proceso penal. Se concluye acentuando el aspecto social de la violación, y comentando las medidas que habría que adoptar a nivel psico-social con objeto de prevenir la aparición de esta conducta.     

Hacia una historia del psicoanálisis

RESUMEN

El autor comienza señalando que la comprensión histórica del psicoanálisis exige un tratamiento plural, cuyo enfoque ilumine las diferentes perspectivas -así como su mutua interrelación- que han venido ilustrando su peculiar entidad. Por ello en este trabajo define de forma sistemática los principales enfoque históricos de los que es susceptible el fenómeno psicoanalítico: analítico-biográfico, socio-cultural, institucional-profesional y epistemológico, señalando los principales intereses temáticos y problemas que incluye cada uno y ofreciendo una selección de fuentes bibliográficas según tres criterios combinados: el mantenimiento de las obras clave clásicas, el carácter contemporáneo de las fuentes y el acceso a las mismas.     

Niveles experimentales de conflicto social e influencia minoritaria: Límites en la definición de influencia indirecta

Resumen

El propósito de la presente investigación es desarrollar una jerarquía experimental que estudie las características más importantes del conflicto social en los procesos de influencia minoritaria. También se hace un análisis de los límites de la influencia latente minoritaria. Se defiende así la idea de que la influencia indirecta de las minorías reposa sobre una relación de naturaleza binaria no transitiva entre las posiciones minoritarias y las opiniones y actitudes objeto de influencia. Para ello se elaboró una serie de experimentos que combinan las siguientes variables, pertenencia categorial y presentatividad de la fuente minoritaria, en un diseño factorial 3 x 2. Los sujetos, 107 escolares (110 mujeres y 87 varones) fueron distribuidos en seis condiciones experimentales resultantes de la combinación de dos clases de variables: fuente de influencia perteneciente a un intragrupo, a un extragrupo, o a una minoría sin categorización social; fuente minoritaria representativa o no representativa. Los resultados subrayan la importancia del conflicto social en la producción de la influencia minoritaria y parecen confirmar la hipótesis de los límites en la influencia indirecta minoritaria.     

Will you thrive under pressure or burn out? Linking anxiety motivation and emotional exhaustion

Can individual differences in the tendency to use anxiety as a source of motivation explain emotional exhaustion? We examined the effects of using anxiety as a source of energy or as a source of information (viewed here as two forms of anxiety motivation) on emotional exhaustion. In Study 1, the use of anxiety as a source of energy predicted decreased emotional exhaustion one year later. Moreover, both forms of anxiety motivation buffered people from the detrimental effects of trait anxiety on later emotional exhaustion. In Study 2, an experiment, participants who were instructed to use anxiety as a source of energy reported lower emotional exhaustion following a stressful task, compared to those instructed to focus on the task or to simply do their best. These findings suggest that using anxiety as a source of motivation may protect people against emotional exhaustion.     

The role of outcome inhibition in interference between outcomes: A contingency‐learning analogue of retrieval‐induced forgetting

Current associative theories of contingency learning assume that inhibitory learning plays a part in the interference between outcomes. However, it is unclear whether this inhibitory learning results in the inhibition of the outcome representation or whether it simply counteracts previous excitatory learning so that the outcome representation is neither activated nor inhibited. Additionally, these models tend to conceptualize inhibition as a relatively transient and cue‐dependent state. However, research on retrieval‐induced forgetting suggests that the inhibition of representations is a real process that can be relatively independent of the retrieval cue used to access the inhibited information. Consistent with this alternative view, we found that interference between outcomes reduces the retrievability of the target outcome even when the outcome is associated with a novel (non‐inhibitory) cue. This result has important theoretical implications for associative models of interference and shows that the empirical facts and theories developed in studies of retrieval‐induced forgetting might be relevant in contingency learning and vice versa.     

Power and conflict in cooperative and competitive contexts

Power and conflict are classic research topics in organizational theory and important practical management issues. The goal of this article was to analyse the influence of supervisor power bases and goal interdependence situations over intragroup conflict. The study involved the participation of 401 workers from a range of social service organizations. Hierarchical regression analyses showed that (a) supervisor personal power bases were negatively associated with task and relationship conflict; (b) supervisor position power bases were positively associated with relationship conflict; (c) cooperative environments were negatively associated with task and relationship conflict; and (d) that goal interdependence moderates the negative consequences of the use of position power. The implications for research and managerial practices are discussed.
