Facilitation and interference of behavioral responses by task-irrelevant affect-laden stimuli

Emotional interference on behavior is commonly observed when task-irrelevant negative stimuli appear before behavioral targets. One explanation postulates that affect-laden stimuli readily capture attention, interfering with the processing of the upcoming target. Emotional stimuli might also preactivate motor programs incompatible with the demanded response. Using a cued go/no-go procedure we showed that task-irrelevant unpleasant stimuli cause interference or facilitation depending on their onset asynchrony relative to the target. We observed interference with short (200 ms) stimulus-target asynchronies and facilitation for longer ones (600 ms), both for key press (Experiment 1) and key release (Experiment 2) responses. The interference effect is compatible with an attentional explanation, but the behavioral facilitation is hard to accommodate within either attentional or motor accounts. This interference-facilitation pattern can be explained assuming that once the attentional effect subsides, emotional processing may enhance the perceptual processing of the stimuli, or lower the decision threshold, thereby facilitating the response selection process.     

Religious upbringing and current religiosity in Spanish nursing and medicine students

The influence of religious education in the family upon current spiritual and religious tendencies was assessed in a sample of 599 Spanish nurse and medicine students using a religiosity scale and answers to a series of belief/disbelief statements. Results showed that nursing and medicine students were equally low-religious, with no differences in religiosity total scores between participants coming from religious families; however, medical students coming from nonreligious families showed higher religiousness than the corresponding nursing trainees. This distinction appeared both across religiosity items and in a variety of responses to belief/disbelief of Christian/secular assertions. Regression analysis showed that religious family background was a consistent predictor of religious beliefs at young adulthood, and its influence was higher for medical students. In addition to establish religious upbringing as an important factor modulating enduring religiosity, these findings provide distinctions between nurse and medical trainees, and reproduce, in a Spanish mainly catholic sample, the structure of religiosity factors previously found on North American mainline protestants.     

Trajectories of Experience of Real Life Events. A Semiotic Approach to the Dynamics of Positioning

This paper is devoted to the study of experience as a semiotic process of constructing the personal meaning of the situation lived. Its main purpose is to devise a semiotic methodology capable of describing and explaining the dynamics of positioning when facing personal lived experiences in real life contexts. Twenty four young adults were exposed to a simulated conflict and then asked to write a narrative of their understanding of the incident and a self-report of their personal experiences. Results show how narratives and trajectories of experience present different forms in each participant, which could be related to: a) the understanding of the situation lived and the position taken regarding the conflict; and b) the position each participant takes regarding the reports they had to produce for the researchers. The incorporation of reflexivity into the applied method allows identification of how the dynamics of double positioning leave traces in the records produced.     

Inhibition of return generated by voluntary saccades is independent of attentional momentum

Summoning attention to a peripheral location, either by a peripheral cue with the eyes fixed or when a voluntary saccade is made to it and gaze is then returned to the centre, delays detection of subsequent targets at that location compared to a location in the opposite visual field. It has been proposed that oculomotor activation generates this inhibition of return (IOR). This account presupposes that the asymmetry in detection results from inhibition at the cued location rather than facilitation at the uncued location. This has been confirmed for exogenously generated IOR. However, it has not, heretofore, been confirmed for “IOR” generated by voluntary saccades. The current study investigated whether the asymmetry in target detection, elicited either by a peripheral flash or by an eye movement generated in response to a central arrowhead, reflects facilitation at the opposite location due to the path of attentional momentum. Reaction times at the cued location were slower than reaction times at the opposite or perpendicular locations, which did not differ. Opposite facilitation due to attentional momentum requires that opposite be faster than perpendicular, which was not obtained. The results were the same whether IOR was generated by an exogenous cue or by a saccade executed endogenously to a central arrow.     

Reflections on trauma,symbolization and psychic pain in a case of neurosis and a case of psychosis

This paper seeks to advance some considerations on trauma, historical reality, its symbolization and the psychic pain generated by the investigation of unconscious processes in psychoanalytic treatment. These themes will be explored by demonstrating the differences arising between traumatic experiences and their expression in phantasy, as they occurred in a case of neurosis and another of psychosis. In each case, the differences in the features of the symbolization and the processes of working through shall also be taken into consideration. Particular attention shall be paid to the specific difficulties encountered by the analyst in the interpretative treatment of the trauma resulting from the amount of psychic pain induced in the patient, which at times proves to be an insurmountable barrier and a destructive distortion of the process.     

Spanish Adaptation of the Working Alliance Inventory-Short (WAI-S)

The goal of our research was to adapt the short forms of the Working Alliance Inventory into the Spanish language for patients and therapists (WAI-S-P and WAI-S-T). The psychometric properties of scores from these measurement instruments were evaluated in Spanish outpatients with depressive disorders and their therapists. The scores of both measures exhibited excellent reliability in terms of internal consistency and excellent convergent validity. Their discriminant validity exhibited some limitations, particularly when the scores of both short measures correlated with those of two empathy measures. Regarding predictive validity, the scores of the overall WAI-S-P and WAI-S-T significantly correlated with residual gain scores of patients in the Beck Depression Inventory (BDI) after the tenth psychotherapy session. Additionally, the overall WAI-S-T scores explained a moderate percentage of the variance in patient BDI score changes. These results are satisfactory and similar to those found in the studies that have utilized the respective original versions of WAI-S in English.     

Animal timing: a synthetic approach

Inspired by Spence’s seminal work on transposition, we propose a synthetic approach to understanding the temporal control of operant behavior. The approach takes as primitives the temporal generalization gradients obtained in prototypical concurrent and retrospective timing tasks and then combines them to synthetize more complex temporal performances. The approach is instantiated by the learning-to-time (LeT) model. The article is divided into three parts. In the first part, we review the basic findings concerning the generalization gradients observed in fixed-interval schedules, the peak procedure, and the temporal generalization procedure and then describe how LeT explains them. In the second part, we use LeT to derive by gradient combination the typical performances observed in mixed fixed-interval schedules, the free-operant psychophysical procedure, the temporal bisection task, and the double temporal bisection task. We also show how the model plays the role of a useful null hypothesis to examine whether temporal control in the bisection task is relative or absolute. In the third part, we identify a set of issues that must be solved to advance our understanding of temporal control, including the shape of the generalization gradients outside the range of trained stimulus durations, the nature of temporal memories, the influence of context on temporal learning, whether temporal control can be inhibitory, and whether temporal control is also relational. These issues attest to the heuristic value of a Spencean approach to temporal control.     

Counterfactual thinking as an issue between language and pretend play / El pensamiento contrafactual como un problema entre el lenguaje y el juego de simulación

Discussions on counterfactual thinking (CT) have been focused on whether it is a language skill or it emerges spontaneously before language acquisition. This paper surveys the most compelling arguments regarding these frameworks: (1) the approach ‘CT as a language skill’; (2) those who claim that pretending shows that children have CT; (3) those who consider pretend play is a rehearsal for cognitive dispositions. I shall point out that the three approaches on CT are incomplete: (1) neglects pretend play (which prelinguistic children perform) as an instantiation of the CT; (2) puts too much emphasis on the linguistic dimension of pretense; (3) is highly demanding on the cognitive architecture that we ought to have by nature — the so-called children as scientists.
