Recently a psychological mechanism has been proposed between bodily purity and moral purity: the “Macbeth effect”. The act of washing their hands seems to free individuals of their guilt. However, the universality of this psychological mechanism is an empirical question that should be studied. In four studies we replicated the original Zhong & Liljenquist's experiments with Spanish samples. We were unsuccessful in replicating the Zhong & Liljenquist's results that supported cleansing as a psychological mechanism for compensating guilty: results couldn't confirm an increased mental accessibility of cleansing-related concepts or even a greater desire for cleansing products, neither a greater likelihood of taking antiseptic wipes. In addition we didn't find that physical cleansing alleviates the upsetting consequences of unethical behaviour. Spanish samples showed sensibility to morality and helping behaviour but not with cleansing as a way to reduce their threatened morality.

In two experiments, we recorded eye movements to study how readers monitor temporal order information contained in narrative texts. Participants read short texts containing critical temporal information in the sixth sentence, which could be either consistent or inconsistent with temporal order information given in the second sentence. In Experiment 1, inconsistent sentences yielded more regressions to the second sentence and longer refixations of it. In Experiment 2, this pattern of eye movements was shown only by readers who noticed the inconsistency and were able to report it. Theoretical and methodological implications of the results for research on text comprehension are discussed.

Recent approaches from social psychology lend support to conspiracy beliefs as a motivated form of social cognition, structured around and consistent with a higher‐order belief system, which may have an impact on the way people understand their political environment and respond to it. Building on these accounts, this study examines the influence of conspiracism on political efficacy and, indirectly, on conventional and unconventional forms of political participation. Drawing on two‐wave panel data collected in five democracies (United States, Japan, United Kingdom, Poland, and Estonia; n = 5,428), results suggest that individuals who hold conspiracy beliefs tend to regard the political system as less responsive to citizens’ demands – external dimension of political efficacy. We also found a less clear and country‐specific effect of conspiracy beliefs on perceptions of being less equipped to partake in the political process – internal efficacy. Furthermore, conspiratorial beliefs negatively affect conventional modes of political participation, indirectly through reduced external efficacy. We finally examine group differences by country that suggest that both individual‐ and contextual‐level factors may explain the observed pattern of influences. Our results emphasize the potential of currently widespread conspiratorial narratives to undermine attitudes and behaviours that lie at the heart of the democratic process.

Understanding verbal descriptions of everyday actions could involve the neural representation of action direction (avoidance and approach) toward persons and things. We recorded the electrophysiological activity of participants while they were reading approach/avoidance action sentences that were directed toward a target: a thing/a person (i.e., "Petra accepted/rejected Ramón in her group"/ "Petra accepted/rejected the receipt of the bank"). We measured brain potentials time locked to the target word. In the case of things, we found a N400-like component with right frontal distribution modulated by approach/avoidance action. This component was more negative in avoidance than in approach sentences. In the case of persons, a later negative event-related potential (545-750 ms) with left frontal distribution was sensitive to verb direction, showing more negative amplitude for approach than avoidance actions. In addition, more negativity in approach-person sentences was associated with fear avoidance trait, whereas less negativity in avoidance-person sentences was associated with a greater approach trait. Our results support that verbal descriptions of approach/avoidance actions are encoded differently depending on whether the target is a thing or a person. Implications of these results for a social, emotional and motivational understanding of action language are discussed.

Linguistic negation acts by inhibiting the representation of information under its scope, often leading to the representation of positive alternative states of affairs. Motivational direction refers to approach/avoidance intentionality in our interactions with environmental stimuli expressed by means of verbs (e.g., "accept" vs "reject"). We consider it plausible that negation interacts with direction to represent the true motivation of the protagonist in sentence understanding (e.g., if an approach action is negated it is represented as avoidance). In the first study, we examine this interaction offline by asking participants to judge approach or avoidance meaning of affirmative (e.g., "he/she included/excluded meat") and negative sentences ("he/she did not include/exclude meat"). Results support that negation reversed participants' interpretation of sentence motivational direction. In a further study, we carried out two probe recognition experiments to examine the interaction during sentence comprehension; in both, the critical probe was the word referring to the target of the action (e.g., "meat"). In the first experiment, participants had to recognize the probe word presented 1500 milliseconds after sentence offset, while for the second one, the delay was 500 milliseconds. Results showed that at 1500 ms, target recognition took significantly more time for negated avoidance sentences than for the other conditions. Therefore, representing negated avoidance sentences seems to imply more complex processing, as avoidance verbs would be implicitly negative. By contrast, at the 500 ms delay, negation impaired target recognition for both approach and avoidance sentences, suggesting an unspecific inhibitory effect of negation at that sentence processing stage. Implication of these results for both research on negation and in action understanding are discussed.

Approach and avoidance tendencies towards valenced others could be associated with our interpersonal conduct towards them: helping would be associated with approach tendency, and harming (or denying help) would be associated with avoidance. We propose that the encoding of this association enjoys attentional priority, as approach/avoidance representations of past interactions would regulate one's predisposition to either help or harm in subsequent interactions. Participants listened to interactions conveying positive/negative conduct between 2 characters. The conduct verb was then presented visually with a cue prompting participants to quickly step forward or backward. Subsequently, they performed a recognition task of noncentral story details. In matching conditions (positive conduct-step forward, negative conduct-step backward) the concurrent step should interfere with the encoding of motor representation of the conduct verb, and the verb encoding should divert attentional resources from the consolidation of memory traces of less relevant information. Results showed the predicted impairment in the recognition task in matching conditions, which supports an attentional bias towards encoding motor approach/avoidance representation of interpersonal conduct in the process of comprehending narrated interactions.

We examine the effect of transcranial direct current stimulation (tDCS) of right superior temporal sulcus (rSTS) in memorization of approach/avoidance relationship-action sentences; for example, “Alejandro accepted/rejected Marta in his group.” Sixty-five university students participated in a tDCS study, in which a between-subjects design was adopted. Sixty-four participants were also given the behavioral approach system (BAS) and behavioral inhibition system (BIS) scales. Participants were subjected to 20 min of stimulation: anodal (N = 24), cathodal (N = 21), or sham (N = 20); subsequently, they were given a list of 40 sentences (half approach and half avoidance) and told to try to memorize them. Finally, they performed a changed/same memory task (half the sentences were the “same” and half were “changed”). Previously, we had examined performance in the memory task without tDCS with another group of participants (N = 20). We found that anodal stimulation improved d’ index of discriminability (hits-false alarms) compared to sham and cathodal conditions for both approach and avoidance sentences. Moreover, the comparison between anodal and task-alone performance showed that stimulation improved d’ index of approach sentences more, as task-alone performance showed better discrimination for avoidance than for approach. Likewise, we explored a potential modulation of tDCS effect by (BAS) and (BIS) traits. We found that d’ index improvement in anodal stimulation condition only benefited low BAS and low BIS participants. Implications of these results are discussed in the context of rSTS function in encoding and memorizing verbally described intentional relationship-actions and the role of individual differences on modulating tDCS effect.

Human brains encode approach in social relationships as cognitively relevant for adaptive behavior. In this study, using event-related potentials (ERPs), we found that reading approach-social actions are likely to cause activation around the right anterior/middle superior temporal sulcus (STS), a brain area particularly involved in processing action intentionality and social relationships. We consider that the human capacity for the mental rotation of figures could also be adaptive for social relationships at the service of planning interaction with other bodies in social encounters. Encoding of social approach and spatial ability would correlate if both capacities are aimed at achieving the adaptive goal of secure interactions with others. We found a strong correlation between brain activation in the right temporal brain region and spatial ability. Implications of these results for the psychological mechanisms involved in adaptive social behavior are discussed.
