Psicología Social del Lenguaje II: Socialización,Interacción y Grupalidad

RESUMEN

En el artículo de Amalio Blanco sobre psicología social del lenguaje se mantiene una reflexión sobre la matriz social en que se sitúan los fenómenos lingüísticos que es continuación de la presentada en el tercer número de Estudios de Psicología. En este caso, se trata de definir el lugar y el papel del hecho lingüístico en los procesos de socialización, considerando la interacción como base de la acción social, y las características compartidas, grupales, de esa acción, que permiten una redefinición de la competencia lingüística. En este trabajo se plantea la necesidad de tener en cuenta los factores pragmáticos y de interacción en la consideración del lenguaje, terminando con algunas reflexiones en torno a la participación del lenguaje en la constitución y cohesión de los grupos.     

The influence of depression symptoms on exploratory decision-making

People with symptoms of depression show impairments in decision-making. One explanation is that they have difficulty maintaining rich representations of the task environment. We test this hypothesis in the context of exploratory choice. We analyze depressive and non-depressive participants’ exploration strategies by comparing their choices to two computational models: (1) an “Ideal Actor” model that reflectively updates beliefs and plans ahead, employing a rich representation of the environment and (2) a “Naïve Reinforcement Learning” (RL) model that updates beliefs reflexively utilizing a minimal task representation. Relative to non-depressive participants, we find that depressive participants’ choices are better described by the simple RL model. Further, depressive participants were more exploratory than non-depressives in their decision-making. Depressive symptoms appear to influence basic mechanisms supporting choice behavior by reducing use of rich task representations and hindering performance during exploratory decision-making.     

Wallace’s and Darwin’s natural selection theories

Synthese - This work takes a stand on whether Wallace should be regarded as co-author of the theory of natural selection alongside Darwin as he is usually considered on behalf of his alleged...     

Human rights and ethnic attitudes in Spain: The role of cognitive, social status, and individual difference factors

Cognitive, individual differences, and intergroup contact factors were examined in the formation of attitudes about human rights and ethnic bias in two studies conducted in Spain. A 7‐item scale measuring knowledge about human rights laws in Spain and the European Union was used in both studies. Participants were university students enrolled at the Universidad Autónoma de Madrid. In study one, participant (n = 127) knowledge about human rights laws, intergroup contact, Right Wing Authoritarianism (RWA), and Gough's Prejudice/Tolerance (Pr/To) scale were examined in relationship to bias towards Gitanos. Findings revealed that knowledge about human rights and social status variables (gender and age) were not significant predictors of Gitano bias, whereas Pr/To, RWA, and contact were all (R² = .28) significant predictors of bias against Gitanos. Findings provided cross‐cultural replication (Dunbar & Simonova, in press) of the relationship of Pr/To and RWA to Gitano bias. In study two, participant (n = 100) knowledge and feelings (measured on a three‐item semantic differential scale) about human rights laws, Pr/To, and RWA were examined in relation to strategies influencing peer attitudes about human rights on the Raven Social Influence Inventory (RSII) scale. Findings indicated that knowledge about human rights laws were correlated (r = .47, p < .001) with positive feelings about these laws. Results of a hierarchical regression analysis, controlling for knowledge about human rights laws and participants' social status, found that the Prejudice/Tolerance scale and feelings about human rights were related with both hard (R² = .11) and soft (R² = .08) social influence strategies influencing peer human rights attitudes on the RSII. Men and higher‐scoring participants on Pr/To both employed more hard social influence strategies. Findings indicate that while knowledge of human rights laws is unrelated to ethnic bias, more accurate knowledge is correlated to more positive feelings about laws meant to protect the rights of ethnic minorities.     

Illusion of control in Internet users and college students.

When people try to obtain a desired event and this outcome occurs independently of their behavior, they often think that they are controlling its occurrence. This is known as the illusion of control, and it is the basis for most superstitions and pseudosciences. However, most experiments demonstrating this effect had been conducted many years ago and almost always in the controlled environment of the psychology laboratory and with psychology students as subjects. Here, we explore the generality of this effect and show that it is still today a robust phenomenon that can be observed even in the context of a very simple computer program that users try to control (and believe that they are controlling) over the Internet. Understanding how robust and general this effect is, is a first step towards eradicating irrational and pseudoscientific thinking.     

THIS ARTICLE HAS BEEN RETRACTED: Enumeration of objects and substances in non‐human primates: experiments with brown lemurs (Eulemur fulvus)

Both human infants and adult non‐human primates share the capacity to track small numbers of objects across time and occlusion. The question now facing developmental and comparative psychologists is whether similar mechanisms give rise to this capacity across the two populations. Here, we explore whether non‐human primates’ object tracking abilities are subject to the same constraints as those of human infants. In particular, we examine whether one primate species, the brown lemur (Eulemur fulvus), also fails to represent and enumerate objects when they behave non‐rigidly or non‐cohesively. We presented lemurs with a series of expectancy violation studies involving simple 1 + 1 addition events in which we varied the entities to be enumerated. Like infants, lemurs successfully enumerated the two objects when those objects were rigid, cohesive individuals, but failed to enumerate similar‐looking non‐rigid piles of sand. In contrast to human infants, however, lemurs successfully enumerated non‐cohesive objects that broke into multiple pieces. These results are discussed in light of recent theories about object processing in human infants and adults.     

Making the uncontrollable seem controllable: the role of action in the illusion of control

It is well known that certain variables can bias judgements about the perceived contingency between an action and an outcome, making them depart from the normative predictions. For instance, previous studies have proven that the activity level or probability of responding, P(R), is a crucial variable that can affect these judgements in objectively noncontingent situations. A possible account for the P(R) effect is based on the differential exposure to actual contingencies during the training phase, which is in turn presumably produced by individual differences in participants' P(R). The current two experiments replicate the P(R) effect in a free-response paradigm, and show that participants' judgements are better predicted by P(R) than by the actual contingency to which they expose themselves. Besides, both experiments converge with previous empirical data, showing a persistent bias that does not vanish as training proceeds. These findings contrast with the preasymptotic and transitory effect predicted by several theoretical models.     

Applying social cognitive career theory to predict interests and choice goals in statistics among Spanish psychology students

This study investigated the usefulness of social cognitive career theory—SCCT (Lent, Brown, and Hackett, 1994) in predicting interests and goals relating to statistics among psychology students. The participants were 1036 Spanish students who completed measurements of statistics-related mastery experiences, self-efficacy, outcome expectations, interests and goals/intentions. Structural equation modeling (including multi-group analysis) was used to test the fit of the hypothesized models to the data. Results indicated support for SCCT as a way to predict students' interests in statistics and their intentions of engaging in academic or professional activities where statistics is used. Collectively, the predictors accounted for 50% of the variance in interests and for 77% of the variance in goals. Implications both for future research on SCCT and for intervention in statistics education are discussed.
