Sobre comportamiento lingüístico. Una evaluación crítica del modelo de Osgood

Resumen

Una revisión de los estudios teóricos y experimentales del modelo comportamental Psicolinguistico de Charles E. Osgood se lleva a cabo. Del análisis del modelo y de su instrumento de validación—el diferencial semántico—se deducen un conjunto de inadecuaciones que sugieren que el lenguaje no puede ser explicado a partir dei uso osgoodiano de la teoría del aprendizaje. A sus inadecuaciones teóricas en relación con la referencia, se suma que el diferencial semántico no constituye un test de condicionamiento, sino una tarea de categorización de memoria inmediata. (Short-term memory.) Los resultados del D.S. se derivan del tipo de diseño experimental.     

La falacia de la validación personal: Más efectos placebo

RESUMEN

En este artículo se pone a prueba la influencia de efectos placebo en la aceptación de informes evaluativos y diagnósticos por los sujetos. Tras introducir brevemente el tema y plantear las hipótesis, los autores describen el método y los resultados de su investigación. En la discusión explican que estos resultados sugieren que la aceptación del diagnóstico que ofrece un profesional es un fenómeno general independiente de las características personales de los individuos que lo reciben, poniendo en entredicho el fenómeno de la validación personal y, al mismo tiempo, interactúa con determinadas características profesionales de los sujetos, ligadas a imágenes de personalidad a las que son más propensos. Los autores también analizan una limitación importante de su trabajo, el tamaño reducido de la muestra, y finalizan destacando que es el contenido del informe, más que el tipo de pruebas o profesionales, lo que parece afectar diferencialmente a distintos grupos profesionales.     

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.     

Are emotional intelligent workers also more empathic?

This paper analyzes whether emotional intelligence and self‐monitoring are related to empathy among a sample of workers in both the public and private employment sectors. Two hundred and forty‐two employees (42.5% men and 57.5% women) with a mean age of 35.21 years (SD = 10.07, range 18–61) completed a questionnaire that measured the variables of interest. The results showed that emotion regulation, a dimension of emotional intelligence, accounts for most of the variance of empathy, followed by the ability to understand emotions and the management of others' emotions. Furthermore, gender did not yield any moderator effect on the relations among emotional intelligence, self‐monitoring and empathy. We conclude that the intrapersonal aspects of emotional intelligence, in particular, emotion regulation, help explain the empathy of workers. The implications of these findings are discussed herein.     

Characterization of PLZT ceramics modified by isovalent (Ba,Sr), donor (Nb) and acceptor (Zn) dopants for piezoelectric applications

This article describes the influence of microstructure on the dielectric and piezoelectric properties of isovalent- donor- and acceptor-modified lead lanthanum zirconium titanate (PLZT) ceramics. The ceramic compositions, with formula: [Pb_0.954La_0.016Ba_0.01Sr_0.02][Zr_0.525Ti_0.475]_{0.981?( m /2)}Nb_0.012Zn _m O₃ where m =?0, 0.2, 0.4, 0.6, 0.8 and 1.0 mol% Zn, were synthesized via a solid-state reaction method. X-ray diffraction studies are supported by tolerance factor and electronegativity difference measurements. Scanning electron microscopy studies reveal grain growth enhancement with increase of Zn concentration. As the Zn concentration increased from 0 to 0.8 mol%, the room-temperature dielectric constant increased while the Curie temperature decreased continuously. An increase in the Zn content had the most significant effect on the piezoelectric properties. The optimum piezoelectric properties were observed for 1 mol% Zn composition.     

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.     

Voices of African Traditional Healers: Cultural Context and Implications for the Practice of Counselling in Sub-Saharan Africa

The healing paradigm implicit in many sub-Saharan African cultures is embedded in African cosmology, and thus the recognition of this is essential for understanding Traditional African Healing practices and implementing collaborative counselling practices. To this end, this article focuses on the cultural importance, or voice, of traditional healers in sub-Saharan Africa. The current article uses an ethnographic approach to analyse systematically the cultural context of indigenous healing practices in sub-Saharan Africa. The anthropological importance of Traditional Healing practitioners, the context of healing, and the changing legal and ethical status of Traditional Healers are addressed as pivotal in furthering the development of this crucial, yet under utilized resource. The authors propose that such cultural understanding is highly relevant to the work of professional counselors.     

Addressing Urgent Community Mental Health Needs in Rwanda: Culturally Sensitive Training Interventions

Rwandan leaders in the health and educational sectors have begun to discuss the necessity for establishing culturally appropriate community-based mental health counselling services in Rwanda, especially trauma counselling. The need for a community psychology approach is anchored in the lingering effects of the genocide and the continuing post-traumatic stress symptoms suffered by many in the population. Capacity building in an effort like this would require the design of multi-level counselling curricula that are sensitive to the social structures within Rwandan culture. These curricular endeavours call for the development of a National Counselling Centre to serve as a structural mechanism for organizing community-based counselling initiatives. We consider the community health services needs in Rwanda here, along with associated challenges and strategies for effective mental health services in a country with a recent history of genocide. A community psychology approach to mental health would benefit Rwandan society by making trauma counselling and recovery services available and accessible to citizens throughout the country.
