Extending the the behavioral immune system to political psychology: Are political conservatism and disgust sensitivity really related?

Previous research suggests that several individual and cultural level attitudes, cognitions, and societal structures may have evolved to mitigate the pathogen threats posed by intergroup interactions. It has been suggested that these anti-pathogen defenses are at the root of conservative political ideology. Here, we test a hypothesis that political conservatism functions as a pathogen-avoidance strategy. Across three studies, we consistently find no relationship between sensitivity to pathogen disgust and multiple measures of political conservatism. These results are contrasted with theoretical perspectives suggesting a relationship between conservatism and pathogen avoidance, and with previous findings of a relationship between conservatism and disgust sensitivity.     

Differential patterns of spontaneous experiential response to a hypnotic induction: A latent profile analysis

A hypnotic induction produces different patterns of spontaneous experiences across individuals. The magnitude and characteristics of these responses covary moderately with hypnotic suggestibility, but also differ within levels of hypnotic suggestibility. This study sought to identify discrete phenomenological profiles in response to a hypnotic induction and assess whether experiential variability among highly suggestible individuals matches the phenomenological profiles predicted by dissociative typological models of high hypnotic suggestibility. Phenomenological state scores indexed in reference to a resting epoch during hypnosis were submitted to a latent profile analysis. The profiles in the derived four-class solution differed in multiple experiential dimensions and hypnotic suggestibility. Highly suggestible individuals were distributed across two classes that exhibited response patterns suggesting an inward attention subtype and a dissociative subtype. These results provide support for dissociative typological models of high hypnotic suggestibility and indicate that highly suggestible individuals do not display a uniform response to a hypnotic induction.     

Extinction memory in the crab Chasmagnathus: recovery protocols and effects of multi-trial extinction training

A decline in the frequency or intensity of a conditioned behavior following the withdrawal of the reinforcement is called experimental extinction. However, the experimental manipulation necessary to trigger memory reconsolidation or extinction is to expose the animal to the conditioned stimulus in the absence of reinforcement. Recovery protocols were used to reveal which of these two processes was developed. By using the crab contextual memory model (a visual danger stimulus associated with the training context), we investigated the dynamics of extinction memory in Chasmagnathus. Here, we reveal the presence of three recovery protocols that restore the original memory: the old memory comes back 4 days after the extinction training, or when a weak training is administered later, or once the VDS is presented in a novel context 24 h after the extinction session. Another objective was to evaluate whether the administration of multi-trial extinction training could trigger an extinction memory in Chasmagnathus. The results evince that the extinction memory appears only when the total re-exposure time is around 90 min independently of the number of trials employed to accumulate it. Thus, it is feasible that the mechanisms described for the case of the extinction memory acquired through a single training trial are valid for multi-trial extinction protocols. Finally, these results are in agreement with those reports obtained with models phylogenetically far apart from the crab. Behind this attempt is the idea that in the domain of studies on memory, some principles of behavior organization and basic mechanisms have universal validity.     

Inter-individual and age differences in exploration, neophobia and problem-solving ability in a Neotropical raptor (Milvago chimango)

Animal innovations have far-reaching ecological and evolutionary consequences. The occurrence and persistence of an innovation require several processes, including exploration, social and asocial learning, and low neophobia. In addition, the identity of the innovator may determine how these new behaviours are socially transmitted. Taking into account inter-individual and age differences, we investigated three correlates of animal innovation: object exploration, neophobia level and novel problem-solving ability in an opportunistic generalist raptor, the Chimango Caracara (Milvago chimango). Eighteen individuals (7 adults and 11 juveniles) were caught during the non-breeding period and housed in individual cages in outdoor aviaries. Each bird was given three tests: exploration, neophobia and problem-solving. Individuals differed in their response to novel situations both within and between age groups. Most of the juveniles were more explorative and had a lower neophobic response to a strange object than adult birds, but both age groups were able to solve a novel problem when given a food reward. In juveniles, neophobia level and problem-solving performance were inversely related; however, we found no relationship between these behaviours in adults. Exploration did not correlate with neophobia or problem-solving ability for either age group. This research is one of the few studies exploring the inter-individual and age differences in behavioural innovation and their correlates in a bird of prey. The explorative tendency, low neophobia and ability to innovate showed by M. chimango may be advantageous for this generalist and opportunistic raptor and might be some of the factors underlying its ecological success.     

Psychopharmakotherapie der Essstörungen

Es gibt eine Reihe von Studien zur Pharmakotherapie der Essst?rungen. Empfehlungen für die pharmakologische Behandlung von Essst?rungen (Anorexia nervosa (AN), Bulimia nervosa (BN), Binge Eating Disorder (BED)), basierend auf der verfügbaren Literatur, werden vorgestellt: Für AN gibt es Hinweise, dass eine ,,Zinksupplementierung“ oder der Einsatz von atypischen Antipsychotika hilfreich sein kann. Für BN zeigen die Studien positive Ergebnisse hinsichtlich des Einsatzes von Antidepressiva, insbesondere für Fluvoxamin und Fluoxetin. Auch für das Antiepilektum Topiramat gibt es positive Studienergebnisse. Bei BED k?nnen bestimmte Antidepressiva und Antiepileptika erfolgreich eingesetzt werden. Jedoch wird weitere Forschung für die Verbesserung der Behandlung von Essst?rungen ben?tigt. Speziell für Anorexia nervosa besteht ein Bedarf für weitere pharmakologische Behandlungsstrategien.     

The Relationship Between Personality and Peers’ Judgments of the Appropriateness of Accommodations for Individuals With Disabilities1

The purpose of this research was to provide a preliminary evaluation of how the personality characteristics of peers, as defined by the 5‐factor model of personality, explained their judgments of the appropriateness of accommodations given to disabled persons. We hypothesized that both agreeableness and openness to experience would be related positively to judgments of appropriateness and that conscientiousness would be related negatively. We also hypothesized that personality dimensions would interact with disability and accommodation types in determining judgments of appropriateness. We obtained partial support for our hypotheses in that the interactions of Disability × Accommodation × Agreeableness as well as Disability × Accommodation × Openness to Experience were significant, although the personality dimensions themselves did not produce significant results.     

The lay distinction between primary and secondary emotions: A spontaneous categorization?

In line with the psychological essentialism perspective, Leyens et al. ( 13 2000) have hypothesized that people attribute different essences to groups and that they attribute more uniquely human characteristics to their own group than to out‐groups. Leyens et al. have focused on two types of emotions, which in Roman languages have specific labels, such as sentimientos and emociones in Spanish. A cross‐cultural study showed that sentimientos (or secondary emotions) are considered uniquely human emotions whereas emociones (or primary emotions) are perceived as nonuniquely human emotions. The present study focuses on whether this categorization into primary and secondary emotions is a spontaneous distinction that people use in their everyday lives, or whether, on the contrary, it is the result of experimental demands. The paradigm “Who says what to whom” was used to test this question. Geometrical shapes of different colours were systematically associated with different stimuli that varied in meaningfulness. In a first condition, shapes were associated with small or large items of furniture (meaningful categories) and with primary and secondary emotions. In a second condition, the items of furniture were replaced by words ending with a vowel or a consonant (meaningless categories). Subsequently, participants had to recognize which shape was associated with each stimulus. Intra‐category errors were significantly more numerous than inter‐category errors, except for the words ending with a vowel or a consonant. Stated otherwise, types of emotions were recognized like the meaningful difference between items of furniture. These results show that the distinction between primary and secondary emotions is an implicit one that people use spontaneously, and not as a result of task demands. The findings are discussed from the perspective of psychological essentialism and inter‐group relations.     

The Horizontal/Vertical Distinction in Cross‐Cultural Consumer Research

We argue for the importance of a relatively new cultural distinction in the horizontal (valuing equality) or vertical (emphasizing hierarchy) nature of cultures and cultural orientations. A review of the existing cross‐cultural literature is presented suggesting that, although the contribution of the horizontal/vertical distinction is sometimes obscured by methods that conflate it with other dimensions, its impact is distinct from that associated with individualism–collectivism. We present studies that highlight several sources of value for the horizontal/vertical distinction—as a predictor of new consumer psychology phenomena and as a basis for refining the understanding of known phenomena. Results support the utility of examining this distinction for the understanding of personal values, advertising and consumer persuasion, self‐presentational patterns, and gender differences. Methodological issues in studying the horizontal/vertical distinction are also discussed.     

Individuality or Conformity? The Effect of Independent and Interdependent Self-Concepts on Public Judgments

When both independent and interdependent self‐concepts are available, priming either self‐concept will increase the accessibility in memory of the motivations and cognitions associated with it. Thus, priming the interdependent self may activate motivation to maintain harmony and conform to others’ opinions, whereas priming the independent self is likely to activate motivation to be independent and to withstand social pressure. Two experiments investigated implications of these possibilities for judgments of risk when participants anticipated (or not) explaining their judgments to others. Participants relied on others’ beliefs only when their interdependent self was primed and they expected they might have to explain their judgments to others. When their independent self was primed, expectations to communicate theirjudgments had no effect. Culture‐based differences in individualism vs. collectivism had no impact on these effects.
