Publication Sintonizando con otro: la teoría polivagal y el proceso de psicoterapia(2022) Dufey D., Michele; Fernández, Ana María; Muñoz Reyes, José AntonioThe present work presents the polivagal theory as a bio-behavioral model of emotional and interpersonal behavior, aiming to identify its theoretical contributions to the study of psychotherapy regarding client´s clinical status, therapeutic process as well as change. A review of the model shows a reconceptualization of interactions among autononomic nervous system and emotionality within interpersonal context, allowing for identifying normal and pathological activation of defensive behavioral strategies (figh-or-flight and immobilization), as well as their inhibition through the social engagement system. Empirical research shows evidence in favor of hypotheses derived from the model in normal and clinical populations. In clinical contexts, the social engagement system is of particular interest as it allows the emergence of interpersonal trustworthy behavior, being a cornerstone in psychotherapy due to its potential diagnostic value for clients, the development of the therapeutic relationships, as well as beneficial outcomes. Lastly, a nascent body of psychotherapy studies assessing the social engagement system (through high frequency heart rate variability-) and its relation with the therapeutic process (i.e. working alliance) and outcomes (i.e. symptom level) are identified. The evidence supports the value of further developing this interdisciplinary line of research and, eventually, incorporating these measurements into the clinical assessment arsenalPublication Jealousy as Predicted by Allocation and Reception of Resources in an Economic Game(2024) Barbato, María Teresa; Fernández, Ana María; Rodríguez-Sickert, Carlos; Muñoz Reyes, José Antonio; Polo; Polo Rodrigo, Pablo; Buss, DavidEvidence is abundant that evolution by selection has produced sex differences in the design of adaptations to solve the problems surrounding reproduction. A prime example is the design of human jealousy, which research suggests is triggered by distinct evoking acts that are specific challenges for women and men in their exclusive reproductive bond. It follows that jealousy would be directed toward driving away interlopers who could potentially threaten the bond with the romantic partner or increase mate retention efforts in response to sex-specific threats. To explore this possibility, we use as a methodological innovation an eco nomic game for the evocation of jealousy. With a modified dictator game, we showed men and women in a committed relationship, conditions in which the partner or an intrasexual rival allocates money to (investing condition), or obtains money from (receiving condition), the partner or an opposite sex third party that they recently met. A sample of 56 heterosexual couples (n =112) participated in a laboratory setting. Our results show the different scenarios of this dictator game exerted the expected evocation of jealousy (controlling individual differences), with women being more jealous by the partner’s allocation of resources to a rival, and men reporting slightly more jealousy by their partner receiving money from a rival. We discuss the implications of this method to advance the comprehension of the adaptive function of sex differences in jealousy, the use of economic games, and possible modifications to improve the similarity of the game to a real assessment of actual male jealousy
