A new look at sensory attenuation. Action-effect anticipation affects sensitivity, not response bias

The systematic association of an action that a person performs with its sensory effects is thought to attenuate that person's perception of the effect of the action. However, whether learned sensorimotor contingencies truly affect perception, rather than just inducing a response bias, has yet to be determined. The experiment presented in this article comprised two parts: an action-effect association phase and a test phase, during which the actions' perceptual effects were tested. During the association phase, specific actions (left-key and right-key presses) were associated with specific visual effects (tilted Gabor patches). In the test phase, participants' left-key presses and right-key presses triggered the onset of a low-contrast tilted Gabor patch in 50% of trials (no stimulus was presented on the remaining 50% of trials). Participants were required to report the presence or absence of this tilted Gabor patch. Our results showed that participants' sensitivity (d') to the Gabor patches was reduced by 10% when the patches were triggered by the action they had previously been associated with. This finding indicates that a person's action does not induce a response bias (c), but changes the perception (d') of the learned action effect.     

Time course of inhibitory processes in bilingual language processing

This study examines the time course of inhibitory processes in Spanish–English bilinguals, using the procedure described in Macizo, Bajo, and Martín. Bilingual participants were required to decide whether pairs of English words were related. Critical word pairs contained a word that shared the same orthography across languages but differed in meaning (interlingual homographs such as pie, meaning foot in Spanish). In Expts 1 and 2, participants were slower to respond to homographs presented along with words related to the Spanish meaning of the homograph as compared to control words. This result agrees with the view that bilinguals non‐selectively activate their two languages irrespective of the language they are using. In addition, bilinguals also slowed their responses when the English translation of the Spanish homograph meaning was presented 500 ms after responding to homographs (Expt 1). This result suggests that bilinguals inhibited the irrelevant homograph meaning. However, the inhibitory effect was not observed in Expt 2 when the between‐trial interval was fixed to 750 ms which suggests that inhibition decayed over time.     

The Short Dark Triad (SD3): Adaptation and Psychometrics among At-Risk Male and Female Youths

The dark triad is a term used to describe a constellation of three socially harmful personality traits: Machiavellianism, psychopathy, and narcissism. The main aim of the present study was to examine the psychometric properties of the Short Dark Triad (SD3) scale, a brief measure of the dark triad, among a sample (N = 412) of male (n = 200) and female (n = 212) at-risk Portuguese youths. Confirmatory factor analysis revealed the three-factor structure of the SD3 obtained an adequate fit, and measurement invariance across gender was demonstrated, although two items per dimension had to be removed. The Portuguese version of the SD3 scale demonstrated satisfactory psychometric properties, specifically the properties of internal consistency, convergent validity, discriminant validity, and known-groups validity, which overall justifies its use among this population. Findings are discussed in terms of the use of the SD3 scale with male and female at-risk youths.     

Role of social skills training in adolescents with social anxiety disorder

Background/Objective: Social skills training (SST) is frequently included in the treatment of social anxiety disorder (SAD) in both children and adolescents, although there is no empirical evidence to support it. Consequently, our objective is to study the role and effects of SST in the treatment of a sample of adolescents with SAD. Method: A total of 108 adolescents diagnosed with generalized social phobia were randomly assigned to two treatment conditions (with and without SST) and a control group waiting list (WLCG). The evaluation included self-report measures, observational tests and blind evaluators. Results: Both interventions significantly reduced the number of social situations feared/avoided with respect to the WLCG, which worsened. Likewise, both interventions were effective but the group with SST obtained better results in the post-test and follow-ups, as well as a lower dropout rate (6:1). Conclusions: The use of SST reduces the dropout rate of treated adolescents and increases the effectiveness of the Intervention Program for Adolescents with Social Phobia.     

Theater and Psychological Development: Assessing Socio-Cognitive Complexity in the Domain of Theater

Theater is a millenary art form that has stably maintained its minimum indispensable elements over the years. Yet, not much is known about the psychological impact of this performing art. A literature review shows a broad and sometimes contradictory spectrum of theoretical and empirical evidence. In the last few decades, however, interdisciplinary studies, namely in the emerging field of neuroaesthetics, has allowed the emergence of new perspectives on the study of the arts. Drawing from these findings, and to better understand the impact of theater in the socio-cognitive development of actors, directors, and other practitioners, this study tested the construction of an instrument exploring complexity of thought in relation to theater. A preliminary study for the Scale of Socio-cognitive Complexity in the Domain of Theatre (SSCDT) showed that, among a sample of 222, individuals with higher levels of experience in acting and directing seem to demonstrate higher levels of cognitive complexity. To our knowledge, this was the first study aiming to develop a simple paper-and-pencil instrument capable of providing data about the psychological impact of theater in terms of socio-cognitive complexity.
