Parenting and management skills: The mediator role of empathy

The present study aimed to test the effect of sex as well as the experience of parenting at the level of empathy and management skills and the mediating effect of empathy on the relationship between the experience of parenting and management skills. No differences were found between men and women concerning management skills. Women had higher empathy levels than men. Being a father or mother increased management skills and empathy levels. However, the experience of parenting interferes with management skills by increasing levels of empathy only in men. Career counselors need to considerer not only the processes inherent to each management task, but also the variables that intensify these competences, integrating emotional and relational dimensions.     

When Stronger Knowledge Slows You Down: Semantic Relatedness Predicts Children's Co‐Activation of Related Items in a Visual Search Paradigm

A large literature suggests that the organization of words in semantic memory, reflecting meaningful relations among words and the concepts to which they refer, supports many cognitive processes, including memory encoding and retrieval, word learning, and inferential reasoning. The co‐activation of related items has been proposed as a mechanism by which semantic knowledge influences cognition, and contemporary accounts of semantic knowledge propose that this co‐activation is graded—that it depends on how strongly related the items are in semantic memory. Prior research with adults yielded evidence supporting this prediction; however, there is currently no evidence of graded co‐activation early in development. This study provides the first evidence that in children the co‐activation of related items depends on their relational strength in semantic memory. Participants (N = 84, age range: 3–9 years) were asked to identify a target (e.g., bone) amid distractors. Children's responses were slowed down by the presence of a related distractor (e.g., puppy) relative to unrelated distractors (e.g., flower)—suggesting that children co‐activated related items upon hearing the name of the target. Importantly, the degree of this co‐activation was predicted by the strength of the target–distractor relation, such that distractors more strongly related to the targets slowed down children to a larger extent. These findings have important implications for understanding how organized semantic knowledge affects other cognitive processes across development.     

Step changes in the intertrial interval in the midsession reversal task: Predicting pigeons' performance with the learning-to-time model

Our goal was to assess the role of timing in pigeons' performance in the midsession reversal task. In discrete-trial sessions, pigeons learned to discriminate between 2 stimuli, S1 and S2. Choices of S1 were reinforced only in the first half of the session and choices of S2 were reinforced only in the second half. Typically, pigeons choose S2 before the contingency reverses (anticipatory errors) and S1 after (perseverative errors), suggesting that they time the interval from the beginning of the session to the contingency reversal. To test this hypothesis, we exposed pigeons to a midsession reversal task and, depending on the group, either increased or decreased the ITI duration. We then contrasted the pigeons' performance with the predictions of the Learning-to-Time (LeT) model: In both conditions, preference was expected to reverse at the same time as in the previous sessions. When the ITI was doubled, pigeons' preference reversal occurred at half the trial number but at the same time as in the previous sessions. When the ITI was halved, pigeons' preference reversal occurred at a later trial but at an earlier time than in the previous sessions. Hence, pigeons' performance was only partially consistent with the predictions of LeT, suggesting that besides timing, other sources of control, such as the outcome of previous trials, seem to influence choice.

Imágenes mentales y desarrollo cognitivo en ciegos totales de nacimiento

Resumen

El objetivo perseguido en este trabajo fue el estudiar las peculiaridades del desarrollo de la imagen mental enlos niños ciegos totales de nacimiento en la edad de adquisición de las operaciones concretas. Para ello se adaptaron algunas pruebas de las utilizadas por Piaget e Inhelder (1966) en su obra sobre la imagen mental, y se aplicaron a 29 ninos ciegos totales de nacimiento entre los 7 y los 15 años de edad, clasificados en 4 niveles de edad. Sus resultados se compararon con los de dos grupos de control de niños videntes, uno de ellos trabajando con los ojos vendados.

Los resultados muestran un retraso importante de los ciegos respecto a los videntes en uso de la visión en las pruebas que se refieren a la evocación de imágenes de configuraciones estáticas complejas, de objetos en movimiento, y de objetos que se transforman. Este retraso se achaca al de la misma cuantía observado en la adquisición de las operaciones concretas. Este desarrollo cognitivo más lento parece deberse únicamente a la modalidad sensorial utilizada, y no a un daño producido por la ceguera congénita, pues los videntes tapados obtienen resultados comparables a los ciegos.     

Psychological distance and reaction time in a Stroop task

Several sources of interference may simultaneously affect the onset of the well-known “Stroop effect.” Among them is the semantic component, which is reflected in the gradient or semantic effect. This effect consists of an increase in the amount of interference as the semantic distance between the word and the color concept decreases. Shepard (Science 237:1317–1323, 1987) relates psychological space, measured through multidimensional scaling, to mean response times. The present investigation aims to study the function relating the semantic gradient with the psychological distance between the word and the color in a Stroop task. After measuring the gradient, we obtained the subjective rating of the degree of dissimilarity of the gradient words with the concept of “color.” In our work, we show that the amount of interference in a Stroop task increases when the semantic distance from the word to the color concept decreases, and it does so exponentially. We replicated the study with different stimuli to test the robustness of the results.     

Relationship Between Childhood Trauma and Sleep Disturbances: The Role of Perceived Stress as a Mediator

The main objective of the current study was to analyze the mediating role of perceived stress on the relationship between childhood trauma and sleep disturbances among the adult population. The sample of this cross-sectional study was composed of 987 Portuguese adults with sleep disturbances, who completed a self-administered questionnaire about childhood trauma, sleep disturbances, and perceived stress. The results of analyses found that in the model that included the variables childhood trauma and perceived stress, both variables were predictors of sleep disturbances; however, perceived stress was the strongest predictor. Regarding the model with the subtypes of maltreatment, only Emotional Abuse predicted sleep problems. Results of the Path Analysis model showed that perceived stress partly mediates the effect of childhood trauma on adult sleep disturbances. This study has clinical implications, supporting the importance of taking into account childhood trauma and perceived stress during the assessment and intervention of sleep disturbances.     

The Discursive Frames of Political Psychology

The aim of this article is to apply elements of contemporary social theory to the major theoretical, methodological, and ideological divisions across political psychology and to consider both the origins and the impact of a range of theories and models. In so doing, we clarify some of the complexity surrounding the discursive and cultural origins of political psychology. On the basis of this analysis, we aim to overcome the redundant binaries and dualisms—both conceptual and geo‐spatial—that have characterized the field up to now. These binary pairs relate to matters of epistemology, ideology, and methodology, and we show how each pair has been the basis of claims made regarding continental differences. As we shall see, such black‐and‐white thinking limits our capacity to understand the nature and potential of political psychology. Instead we wish to encourage a greater degree of universalism and globalism that is appropriate to political psychology as it evolves into a broader global discipline. We argue that political psychology as a field must attempt to deal with the consequences of an increasingly borderless world in which political identities are becoming more fluid, increasingly hybridized, and open to transformation.     

Roger Swyneshed’s Obligationes: A Logical Game of Inference Recognition?

In [Dutilh Novaes, Medieval-obligations as logical Games of Consistency maintenance, synthese, (2004)], I proposed a reconstruction of Walter Burley’s theory of obligationes, based on the idea that Burley’s theory of obligationes could be seen as a logical game of consistency maintenance. In the present paper, I intend to test the game hypothesis on another important theory of obligationes, namely Roger Swyneshed’s theory. In his treatise on obligationes [edited by P.V. Spade, cf. Spade History and philosophy of Logic 3(1982) 1-32], Swyneshed introduced significant modifications to the general framework of obligationes. To compare the two theories, I apply the same formal apparatus used in the previous paper. It will become patent that Swyneshed’s theory is considerably different from Burley’s, among other reasons because the dynamic aspects that play a major role in the latter are simply not present in the former. My conclusion is that Swyneshed’s version of obligationes is not directed towards consistency maintenance, but rather towards inference recognition, and that it is, from a game-theoretical perspective, less interesting a theory than Burley’s.
