    Chilean Version of the Empathy Quotient (EQ) Scale: Adaptation and Psychometric Properties
    (2021) Fernandez, Ana Maria; Baeza, Carmen Gloria; Pavez, Paula; Aldunate, Nerea
    We evaluated the psychometric properties of the empathy quotient (EQ) scale translated to Spanish in Chile. We estimated its structural validity, and its construct validity with other convergent measures of empathy and attachment, as well an inversely associated construct such as aggression. We used a general sample of students and community individuals (n = 336). Participants completed the EQ, Interpersonal Reactivity Index (IRI), and Buss-Perry Aggression Questionnaire (BPAQ). Another exclusively community group (n = 102) completed Collins Adult Attachment scale and the EQ. CFA and ESEM analyses confirmed the structural model fit of the data to three previously reported dimensions of the EQ: cognitive empathy (CE), emotional reactivity (ER) and social skills (SS). Sex-differences in emotional reactivity, and the predicted relationships with the convergent measures were observed. The current Chilean version of the EQ resulted in an appropriate multidimensional measurement of empathy. Finally, providing a specific social skills dimension extends the traditional conception of cognitive and affective empathy to the social realm in the Chilean context.

    Electrophysiological evidence of different interpretative strategies in irony comprehension
    (2007) Cornejo, Carlos; Simonetti, Franco; Aldunate, Nerea; Ibanez, Agustin; Lopez, Vladimir; Melloni, Lucia
    We explore the hypothesis that induction of holistic or analytic strategies influences comprehension and processing of highly contextualized expressions of ordinary language, such as irony. Twenty undergraduate students were asked to categorize as coherent or incoherent a group of sentences. Each sentence completed a previous story, so that they could be ironical, literal or nonsensical endings. Participants were asked to evaluate whether each sentence was coherent or incoherent. Half of them were initially instructed to consider whether the sentences made sense (holistic condition); the other half were instructed to consider whether the sentences were congruent or incongruent (analytic condition). Behavioral responses and Event Related Potentials were registered during the experiment. Both behavioral and electrophysiological results allow clearly distinguishing between the holistic and the analytic strategies. The fact that the same set of stimuli elicits different ERP waveforms, depending on the strategy with which they are analyzed, suggests that different cognitive processes and different areas of the brain are operating in each case.

    Gesture and metaphor comprehension: Electrophysiological evidence of cross-modal coordination by audiovisual stimulation
    (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009) Cornejo, Carlos; Simonetti, Franco; Ibanez, Agustin; Aldunate, Nerea; Ceric, Francisco; Lopez, Vladimir; Nunez, Rafael E.
    In recent years, studies have suggested that gestures influence comprehension of linguistic expressions, for example, eliciting an N400 component in response to a speech/gesture mismatch. In this paper, we investigate the role of gestural information in the understanding of metaphors. Event related potentials (ERPs) were recorded while participants viewed video clips of an actor uttering metaphorical expressions and producing bodily gestures that were congruent or incongruent with the metaphorical meaning of such expressions. This modality of stimuli presentation allows a more ecological approach to meaning integration. When ERPs were calculated using gesture stroke as time-lock event, gesture incongruity with metaphorical expression modulated the amplitude of the N400 and of the late positive complex (LPC). This suggests that gestural and speech information are combined online to make sense of the interlocutor's linguistic production in an early stage of metaphor comprehension. Our data favor the idea that meaning construction is globally integrative and highly context-sensitive. (C) 2008 Elsevier Inc. All rights reserved.

    Influence of violent contexts on facial reactions elicited by angry and neutral faces
    (2020) Aldunate, Nerea; Lopez, Vladimir; Barramuno, Mauricio; Galvez-Garcia, German
    This study focuses on determining whether violent contexts influence the perception of aggressiveness in faces analysing spontaneouscorrugator superciliiactivity. Participants viewed pictures of neutral and angry faces preceded by a contextual sentence describing either violent or neutral actions. They were instructed to judge each face according to whether it was aggressive or non-aggressive. Results show a higher level of perceived aggressiveness for neutral faces preceded by violent contexts, accompanied by longer reaction times, and a significant increase of corrugator activity. Angry faces preceded by neutral contexts were judged as less aggressive and elicited less corrugator activity. In conclusion, our results provide evidence that facial reactions and aggressiveness judgment for faces are context-dependent. With this work, we contribute to the view that contextual cues guide the face's emotional meaning, under top-down processing.

    Interparty attitudes in chile: Coalitions as superordinate social identities
    (BLACKWELL PUBLISHING, 2008) Gonzalez, Roberto; Manzi, Jorge; Saiz, Jose L.; Brewer, Marilynn; de Tezanos Pinto, Pablo; Torres, David; Aravena, Maria Teresa; Aldunate, Nerea
    This paper reports a survey (N = 1,465) conducted in Chile that was conceived to understand the role of coalition identification as an important sociopsychological mechanism for promoting positive affects toward own-coalition party members in a multiparty system, above and beyond interparty political differences. Participants judged their own political party, parties within coalitions (fellow coalition members and opposing parties), and political coalitions as a whole on affective dimensions (trust, liking, and admiration). The results provide substantial support for the five hypotheses addressed in the study. Overall, perceived interparty distance and political identity threat had a negative impact on affect toward coalition party members. Above and beyond these effects, identification with the coalition positively predicted affect toward allies. Ingroup party affect was positively correlated with affect toward own-coalition party members and own coalition as a whole, but was not negatively associated with affect toward opposing-coalition parties. Moreover, the relationship between own-party affect and affect toward own-coalition party members was mediated by affect toward own coalition. Overall, evidence for the benefits of promoting coalition identification in a multiparty system is provided and discussed alongside the limitations and practical implications derived from the study.
