Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.     

Inhibitory and facilitatory effects of cue onset and offset

The response speed to a visual target is modulated by the position of previous events (cues) even if their position is not predictive of the target position. The modulation has been considered biphasic, with an early facilitatory and a later inhibitory component. We conducted three experiments that investigated the importance of the onset and offset features of the cue for the facilitatory and inhibitory effects and estimated their separate and joint effects. The two possible target locations, one in the right and one in the left visual field, were indicated by two empty boxes, and the cue consisted of the onset and/or offset of an arrowhead located just under one of the two boxes. Different time intervals were used between cue and target. Subjects were instructed to ignore the cue and to respond to the target (a cross inside one of the two boxes). The data showed only consistent effects of inhibition (inhibition of return) with the long intervals, but the pattern was different depending on the cue type. The amount of inhibition was much greater when the onset of the cue was followed by its offset. Apparently, inhibition of return depended on the dynamic changes of the cue.

Juvenile drug addiction: a typology of heroin addicts and their families

In this article the authors propose: 1) a typology of drug addiction cases consisting of four main classes: A. traumatic drug addiction, B. drug addiction from actual neuroses, C. transitional drug addiction, and D. sociopathic drug addiction; 2) a clinical study (with 18 months of follow-up data) involving 131 heroin addicts mostly treated with structural or counterparadoxical family therapy in the same psychotherapy center and in the same year; and 3) some preliminary conclusions emerging from an examination of the four-class typology with respect to the effectiveness of family therapy interventions. If, for example, structural family therapy techniques seem more suitable in type-B cases (similar to cases described by Haley in his Leaving Home), the counterparadoxical techniques are likely to be more effective in type-C cases (similar to the anorectics described by Selvini-Palazzoli).     

Evaluation of A Single Presentation Format For Education About Human Immunodeficiency Virus (HIV) Disease1

This study explored the efficiency and effectiveness of a single presentation format for education about human immunodeficiency virus (HIV) disease. Pretraining and posttraining questionnaires assessing knowledge and risk assessment were given to police officers attending a two-hour seminar on HIV disease. A one-way ANOVA was used to compare posttraining scores of 42 officers who attended the seminar one year ago with the pretraining scores of 63 officers currently attending the seminar, some of whom had attended the seminar one year earlier. Significant differences were found on knowledge items (p < .05). Post hoc analysis revealed no significant decline in knowledge scores after one year, while pretraining knowledge scores for those who had attended the seminar before were significantly greater than for those who had not. No significant differences were found on risk assessment items, suggesting that beliefs about on the job risk have become part of the officers' common culture.     

Beyond family‐level adversities: Exploring the developmental timing of neighborhood disadvantage effects on the brain

A growing literature suggests that adversity is associated with later altered brain function, particularly within the corticolimbic system that supports emotion processing and salience detection (e.g., amygdala, prefrontal cortex [PFC]). Although neighborhood socioeconomic disadvantage has been shown to predict maladaptive behavioral outcomes, particularly for boys, most of the research linking adversity to corticolimbic function has focused on family‐level adversities. Moreover, although animal models and studies of normative brain development suggest that there may be sensitive periods during which adversity exerts stronger effects on corticolimbic development, little prospective evidence exists in humans. Using two low‐income samples of boys (n = 167; n = 77), Census‐derived neighborhood disadvantage during early childhood, but not adolescence, was uniquely associated with greater amygdala, but not PFC, reactivity to ambiguous neutral faces in adolescence and young adulthood. These associations remained after accounting for several family‐level adversities (e.g., low family income, harsh parenting), highlighting the independent and developmentally specific neural effects of the neighborhood context. Furthermore, in both samples, indicators measuring income and poverty status of neighbors were predictive of amygdala function, suggesting that neighborhood economic resources may be critical to brain development.     

The rubber hand illusion: sensitivity and reference frame for body ownership

When subjects view stimulation of a rubber hand while feeling congruent stimulation of their own hand, they may come to feel that the rubber hand is part of their own body. This illusion of body ownership is termed 'Rubber Hand Illusion' (RHI). We investigated sensitivity of RHI to spatial mismatches between visual and somatic experience. We compared the effects of spatial mismatch between the stimulation of the two hands, and equivalent mismatches between the postures of the two hands. We created the mismatch either by adjusting stimulation or posture of the subject's hand, or, in a separate group of subjects, by adjusting stimulation or posture of the rubber hand. The matching processes underlying body ownership were asymmetrical. The illusion survived small changes in the subject's hand posture, but disappeared when the same posture transformations were applied to the rubber hand. Mismatch between the stimulation delivered to the subject's hand and the rubber hand abolished the illusion. The combination of these two situations is of particular interest. When the subject's hand posture was slightly different from the rubber hand posture, the RHI remained as long as stimulation of the two hands was congruent in a hand-centred spatial reference frame, even though the altered posture of the subject's hand meant that stimulation was incongruent in external space. Conversely, the RHI was reduced when the stimulation was incongruent in hand-centred space but congruent in external space. We conclude that the visual-tactile correlation that causes the RHI is computed within a hand-centred frame of reference, which is updated with changes in body posture. Current sensory evidence about what is 'me' is interpreted with respect to a prior mental body representation.     

Uncovering the Motivational Core of Traits: The Case of Conscientiousness

Knowledge of the motivational bases of conscientiousness would be crucial for disentangling competing explanations about the processes underlying this trait. Thereby, building on the results of a previous investigation identifying 21 goal classes connected to conscientiousness, we performed three studies aimed at clarifying the full spectrum of goals and motives underlying this trait. In Study 1 (N = 299), we conceptually replicated the original associations between goal classes and conscientiousness poles, and we identified nine goal classes that individuals ascribe to conscientious profiles more than to other profiles. In Study 2 (N = 329), we examined the associations between the subjective importance of conscientious and unconscientious goal classes and personality traits, as well as the role of goals for the desire to change one's conscientiousness. In Study 3 (N = 432), we developed a 72-item assessment of nine goal classes and explored their connections with the most important facets of conscientiousness, self-control, future orientation, and the consideration of future consequences, using network analysis. We discuss the relevance of our results for research on conscientiousness and its underlying processes. © 2020 European Association of Personality Psychology
