Indicadores aislados versus patrón general expresivo en la detección de la mentira

Resumen

Frente a planteamientos teóricos clásicos, en relación con el fenómeno de la detección de la mentira, que postulan que la existencia de indicadores no verbales aislados facilitan el reconocimiento de mensajes falsos, este trabajo plantea la existencia de un patrón general de configuración que varía cualitativamente para mensajes verdaderos y falsos. Las condiciones experimentales ideadas para este trabajo (presentación de mensajes falsos, precedidos o no de mensajes verdaderos) permitieron a los sujetos experimentales contrastar las diferencias entre estos patrones, facilitando el reconocimiento de mensajes fraudulentos, siendo las mujeres las que mejor aprovecharon las condiciones facilitadoras.     

Antecedentes y aparición de la Psicología del Procesamiento de Información: un estudio histórico

Resumen

El presente artículo recopila los grandes hitos asociados al surgimiento de la Psicología del Procesamiento de Información (principales autores, obras, instituciones, eventos científicos, etc.) en Gran Bretaña y Estados Unidos, países en donde este enfoque tiene su origen. Esto se hace a través de una perspectiva de análisis histórico que, remontándonos a los años veinte—y tras pasar revista a los acontecimientos más relevantes para la Historia de la Psicología acaecidos durante los años treinta, cuarenta y cincuenta—, nos conduce a 1958, fecha clave para el nacimiento y difusión de lo que hoy conocemos como Psicología del Procesamiento de Información.     

Drawing mixed emotions: Sequential or simultaneous experiences?

With a view to measuring subjective experience of mixed emotions, we designed an Analogical Emotional Scale (AES). This scale permits the analysis of how, at the subjective level, the emotions evolve from the beginning to the end of the experience, allowing discrimination between simultaneous mixed emotional experiences (i.e., two emotions taking place at the same time) and sequential mixed emotional experiences (i.e., two emotions switching rapidly back and forth). In Study 1 we asked participants to recall a naturally occurring situation, in Study 2 we induced simple vs. mixed emotions in a controlled situation, and in Study 3 we manipulated the structure of emotional stimuli, sequential versus simultaneous. The results showed that the combined use of rating scales and the AES permits us to obtain a more accurate estimation of the actual presence of simultaneous mixed emotional experiences.     

Authentic leadership and its relationships with work engagement and organizational citizenship behaviors in military units: The role of identification as a mediating variable

The objective of the study is to explore the relationship of authentic leadership with work engagement and organizational citizenship behaviors (OCB) in military units, measuring the mediating effect of personal identification with the leader and social identification with the military unit. We used the Structural Equation Modeling (SEM) technique to analyze data from a sample of 225 Spanish military troops. The results showed that social identification with the military unit influenced the relationship of authentic leadership with the outcome variables.     

Successful aging: criteria and predictors

In the Anglo-Saxon scientific literature, successful aging has been consolidated during the last four decades. Nevertheless, several terms have been used as synonymous: healthy, active, productive, optimal, positive aging. Although, all these terms have been described through a broad set of bio-psycho-social factors, usually, research in this field reduces successful aging to daily life functioning and physical health. Also, in spite of the fact that authors consider that determinants might be multi-domain, empirical research usually reduces them to life styles. Logically, the prevalence of this kind of ageing found empirically is not very consistent and research of its determinants or predictors refers to biomedical conditions. In this study, data from 458 participants (170 males and 288 females; mean age: 66.47, range: 55-75) from ELEA ("Longitudinal Study of Active Aging") were examined. The results show (depending on the simple or multidimensional definitions used) a very varied range of proportions of successfully aging older persons as well as a large number of multi-domain predictors of successful ageing, among which are intelligence, personality and motivational psychological characteristics.     

Ecocultural effects on self‐concept. A study with young indigenous people from different sociodemographic contexts

This study explores self‐concept among indigenous young people from different ecocultural niches in Chiapas (Mexico) through a particular self‐concept task. Previous theory and research has described 3 cultural models linked with specific sociodemographic settings that foster particular psychologies. Our aim was to compare the results of the self‐concept test among indigenous groups from different sociodemographic settings in order to observed possible differences. We predicted that individuals from rural communities with little formal education (hypothesised to be Interdependent) would have self‐concepts with more social and less personal components than would those with an urban, highly educated (hypothesised to be Independent), and we expected a third group of highly educated young people living in an urban context but with a rural background (hypothesised to be autonomous‐related group) to value social and personal components equally. The results supported this hypothesis. Based on ecocultural theory, it is suggested that sociodemographic contexts affect the self‐concept.     

Abstractness and Messages Describing Consequences Promote Healthier Behavioral Intentions

Many health-risk behaviors present a self-control conflict in which the short-term outcomes of an action conflict with its long-term consequences. Across three studies, we find that an abstract construal level leads people to focus on long-term rather than short-term consequences when both are described in a message (vs. no message). Studies 1 and 2 explore this hypothesis through a risk behavior (snacking on sugary products), and Study 3 does the same through a health behavior (physical exercise). In Study 1, the Behavioral Identification Form scale is used to measure the construal level as a personal disposition; Studies 2 and 3 use a priming task designed by Freitas, Gollwitzer, and Trope to manipulate the construal level. All these studies show that, under an abstract mindset, people who have read a mixed-outcome message (vs. no message) tend to base their behavioral plans on long-term outcomes. Individually or in small groups (e.g. school class, therapy groups) health messages can be presented along with protocols to change construal level and thus, promote healthier intentions.     

NIM: A Web-based Swiss army knife to select stimuli for psycholinguistic studies

NIM is Web-based software developed to help experimenters with some of the usual tasks carried out in psycholinguistic studies. It allows the user to search for words according to several variables, such as length, matching substrings, lexical frequency, or part of speech, in English, Spanish, and Catalan. NIM also provides the user with the possibilities to obtain different word metrics, such as lexical frequency, length, and part of speech; to find intralanguage and cross-language lexical neighbors; and to get control words for critical stimuli. Regardless of the language used, the program also enables the user to get the orthographic similarity between word pairs and to identify repeated items in lists of experimental stimuli. NIM is free and is publicly available at http://psico.fcep.urv.cat/utilitats/nim/.     

Moved by words: Affective ratings for a set of 2,266 Spanish words in five discrete emotion categories

The two main theoretical accounts of the human affective space are the dimensional perspective and the discrete-emotion approach. In recent years, several affective norms have been developed from a dimensional perspective, including ratings for valence and arousal. In contrast, the number of published datasets relying on the discrete-emotion approach is much lower. There is a need to fill this gap, considering that discrete emotions have an effect on word processing above and beyond those of valence and arousal. In the present study, we present ratings from 1,380 participants for a set of 2,266 Spanish words in five discrete emotion categories: happiness, anger, fear, disgust, and sadness. This will be the largest dataset published to date containing ratings for discrete emotions. We also present, for the first time, a fine-grained analysis of the distribution of words into the five emotion categories. This analysis reveals that happiness words are the most consistently related to a single, discrete emotion category. In contrast, there is a tendency for many negative words to belong to more than one discrete emotion. The only exception is disgust words, which overlap least with the other negative emotions. Normative valence and arousal data already exist for all of the words included in this corpus. Thus, the present database will allow researchers to design studies to contrast the predictions of the two most influential theoretical perspectives in this field. These studies will undoubtedly contribute to a deeper understanding of the effects of emotion on word processing.
