Event-related potentials and semantics: an overview and an integrative proposal.

Event-related potentials have shown to be a valuable tool when studying language processing. In this review we focus on the literature that deals with semantic processing. Thus, we review studies concerning the classic semantic-related ERP component, the N400, those concerning the recently described recognition potential (RP), and studies that have attempted to identify brain activations related to semantic processing without focusing on specific ERP components. From the available data we provide an integrative proposal. According to this proposal, ERPs are clear indexes of the three subprocesses presumable involved in semantic comprehension. ERPs would provide, additionally, information about the time course of such subprocesses.     

Remembering and constructing an order

The purpose of this study was to determine whether children who could recognize a linear order would be able to use this recognition to answer new questions about the linear order. Three-, 4-, 5-, and 6-year-old children were trained to choose a series over a nonseries, a series over a series ordered in the opposite direction, or one nonseries over another nonseries. They were also given a standard seriation task. Children could recognize a series before being able to construct one, but recognition of a series was not correlated with construction of a series. Although children did not use the linear order to construct a series, they could use it to make choices between two similar stimuli, only one of which contained a feature identical to the linear order. The comparison between seriation and recognition of one nonseries over another revealed that performance on these two tasks was correlated and that one common feature between them was systematicity, which occurred either in searching for relationships or constructing them.     

Empowerment and team effectiveness: an empirical test of an integrated model

The authors developed a model of team empowerment as an emergent state linking inputs (I) with processes (P) and, thereby, with outcomes (O) in the context of an expanded team IPO framework. Using survey responses from 452 members of 121 empowered service technician teams, along with archival quantitative performance and customer satisfaction criteria, the authors tested the model using structural equation modeling techniques. The model was generally supported, although areas for improvement were evident. Specifically, empowerment partially mediated the influences of various inputs on team processes, whereas team processes fully mediated the influence of empowerment on outcomes. Directions for future research and application are discussed.     

Coping with an ego-threat: Monitoring and blunting during an intelligence test

This study investigated the predictive validity of the Miller Behavioral Style Scale (MBSS; Miller, 1987). Subjects had to work on an intelligence test. During this test, they could observe lights that informed them on how they were performing. There were two conditions: a low-stress condition (n = 37) in which the lights always indicated that the subject was performing well, and a high-stress condition (n.= 33) in which the lights signalled a deterioration of performance. In general, little support was found for the predictive validity of the MBSS.     

The Incompleat Projectivist: How to be an Objectivist and an Attitudinist

What is at stake in the dispute between moral objectivism and subjectivism is how we are to give a rational grounding to ethical first principles or basic commitments. The search is for an explanation of what if anything makes any commitments good . Subjectivisms such as Blackburn's quasi -realism can give any set of commitments no 'rational grounding' in this sense except in considerations about internal consistency. But this is inadequate. Internal consistency is not sufficient for ethical rationality, since a set of obviously bad commitments could be internally consistent. Nor is it necessary, since a set of obviously good commitments could be internally inconsistent. I therefore argue for an objectivist view of the grounding of commitments, taking them to be attitudes which get their rationality, or lack of it, from their responsiveness to natural human needs and well-being. Since this view is objectivist, it avoids the problems which face subjectivism.     

Preschoolers' attention and emotion in an achievement and an effect game: A longitudinal study

Understanding positive emotions' shared and differentiating features can yield valuable insight into the structure of positive emotion space and identify emotion states, or aspects of emotion states, that are most relevant for particular psychological processes and outcomes. We report two studies that examined core relational themes (Study 1) and expressive displays (Study 2) for eight positive emotion constructs—amusement, awe, contentment, gratitude, interest, joy, love, and pride. Across studies, all eight emotions shared one quality: high positive valence. Distinctive core relational theme and expressive display patterns were found for four emotions—amusement, awe, interest, and pride. Gratitude was associated with a distinct core relational theme but not an expressive display. Joy and love were each associated with a distinct expressive display but their core relational themes also characterised pride and gratitude, respectively. Contentment was associated with a distinct expressive display but not a core relational theme. The implications of this work for the study of positive emotion are discussed.

Personality and experience in an encounter-group

In a study of seventeen subjects who had participated in an encounter-group, the subjective experience seemed to be related to personality traits. The more obsessive students felt that they had experienced a positive effect from the group, but at the same time they felt that the group was disgusting. The more oral individuals felt that the group had created emotional strain. The more hysterical persons tended to be unaffected by the group experience.     

Juvenile psychopathy and judicial decision making: an empirical analysis of an ethical dilemma

In the burgeoning juvenile psychopathy literature, there is a debate on whether it is appropriate to apply this construct to youths. Some have suggested that labeling children/adolescents as psychopathic might result in negative consequences, such as being recommended for more restrictive placements. However, the scant evidence is equivocal. This study provides additional insights on this issue by assessing judicial perceptions and recommendations to a hypothetical case. Results indicate that psychopathy influenced perceptions of amenability (eta = .12) and dangerousness (eta = .25), and recommendations for placement (eta = .11). More specifically, youth who were both labeled as psychopathic and ascribed psychopathic traits were viewed as less amenable to treatment and more dangerous and were more likely to be recommended for a restrictive placement than youth who were neither labeled nor described as such. The effect of psychopathy on placement recommendations, however, was not significant after controlling for perceptions of dangerous. This suggests that the influence of psychopathy on judicial restrictiveness may operate through the perceived dangerousness of the youth.     

ArduiPod Box: A low-cost and open-source Skinner box using an iPod Touch and an Arduino microcontroller

This article introduces the ArduiPod Box, an open-source device built using two main components (i.e., an iPod Touch and an Arduino microcontroller), developed as a low-cost alternative to the standard operant conditioning chamber, or “Skinner box.” Because of its affordability, the ArduiPod Box provides an opportunity for educational institutions with small budgets seeking to set up animal laboratories for research and instructional purposes. A pilot experiment is also presented, which shows that the ArduiPod Box, in spite of its extraordinary simplicity, can be effectively used to study animal learning and behavior.     

Familiarity and emotional expression influence an early stage of face processing: an electrophysiological study

Recent data indicate that the familiarity and the emotional expression of faces occur at an early stage of information processing. The goal of the present study was to determine whether these two aspects interact at the structural encoding stage as reflected by the N170 component of event-related potentials in tasks requiring the subjects either to identify whether the faces were familiar or the nature of the emotional expression. The results indicate that the neural responses to level of familiarity and emotional expression were observable at this early processing stage but without interacting. In particular, faces of personal importance to the subjects differed from those of less personal importance. Because familiarity did not interact with emotional expression at behavioral and electrophysiologic levels, our results support the contention of parallel and independent processing of faces.
