The hide-and-seek of retrospective revaluation: recovery from blocking is context dependent in human causal learning

In a typical blocking procedure, pairings of a compound consisting of 2 stimuli, A and X, with the outcome are preceded by pairings of only A with the outcome (i.e., A+ then AX+). This procedure is known to diminish responding to the target cue (X) relative to a control group that does not receive the preceding training with blocking cue A. We report 2 experiments that investigated the effect of extinguishing a blocking cue on responding to the target cue in a human causal learning paradigm (i.e., A+ and AX+ training followed by A- training). The results indicate that extinguishing a blocking cue increases conditioned responding to the target cue. Moreover, this increase appears to be context dependent, such that increased responding to the target is limited to the context in which extinction of the blocking cue took place. We discuss these findings in the light of associative and propositional learning theories.     

The induction of shared identity: the positive role of individual distinctiveness for groups

This article examines inductive processes of social identity formation, the bottom-up processes by which individual group members influence a social identity, integrating it with work on entitativity. Three studies tested the prediction that feelings of individual distinctiveness mediate the relation between inductive social identity formation and entitativity and that entitativity in turn predicts identification. The studies provided consistent support for this theoretical model over alternative models, using a range of different social groups and methods. Study 1 found support for the model in self-selected small groups. Study 2 supported it with a much broader set of groups that were not self-selected. Finally, Study 3 varied levels of inductive social identity formation systematically by varying group size and provided direct support for the hypothesized causal relations.     

Reciprocal teaching and self-monitoring of strategy use: effects on reading comprehension

Reciprocal teaching (RT) is an instructional procedure to teach students cognitive strategies that might lead to improved reading comprehension. However, self-monitoring (SM) strategy use can optimize instruction of comprehension. Thus, the present study analyzed: (a) the efficacy of RT in regular classes and (b) the efficacy of RT + SM of strategy use. A sample of 59 students in the fourth year of primary education was selected: 19 children were selected as an RT condition, 18 as an RT + SM condition, while the remaining 22 made up the comparison group. Two types of comprehension measures were used: tasks of specific effects (getting the main idea, writing a summary, comprehension-monitoring test) and transfer effect measures (standardised tests, word meaning inference, and free recall). Thus, the results show that both the RT condition and the RT + SM condition benefited from the instruction, performing better than the comparison group in measures of specific effects and in some of the transfer effect measures. This result shows that SM is not a necessary component in the instruction of reading comprehension with RT.     

Coping strategies and quality of life among liver transplantation candidates

The maintenance of self-reported quality of life (QL) among people on the liver transplantation waiting list is one of the priority objectives of transplantation teams. Although there are different determinant factors of QL, results are not conclusive. In our study, the goal was to evaluate both the influence of cirrhosis etiology (ethylic and non-ethylic) and the coping strategies used concerning QL. A sample of 93 patients was selected, divided into two groups: ethylic cirrhosis (EC) and non-ethylic cirrhosis (NEC). QL was evaluated through the SF-36 Health Survey, and coping strategies through the Medical Coping Modes Questionnaire (MCMQ). Our results indicated that subjects with EC obtained similar QL levels to subjects with NEC, on all the SF-36 and MCMQ subscales. Furthermore, negative correlations were found between avoidance and acceptance-resignation coping strategies with the SF-36 components. Consequently, the acceptance-resignation strategy was associated with a worse perception of physical functioning, general and mental health, and vitality and role-emotional. Overall, these results suggest that cirrhosis etiology is not a determinant factor of QL, whereas the acceptance-resignation coping strategy might lead to lower self-perception of QL.     

Sleep architecture in patients with fibromyalgia

The main objective of this work was to evaluate the characteristics of sleep in patients diagnosed with fibromyalgia syndrome. Sleep architecture in 32 patients with fibromyalgia and 20 healthy controls was evaluated. Following the recommendations of the International Federation of Clinical Neurophysiology, polysomnographies were conducted with fibromyalgia patients and the control subjects. The fibromyalgia patients showed alterations in cyclic organization of sleep and an increased number of periodic leg movements associated with cortical arousals. No significant differences were found in respiratory and oximetry variables or in alpha-delta sleep. The results support that fibromyalgia patients present an increase of superficial sleep at the expense of deep sleep and also an increase of periodic leg movements, which could have a pathogenic effect, facilitating the onset of the illness. Lastly, we discuss the results and propose some future lines of research.     

Aligning Mars and Venus: The Social Construction and Instability of Gender Differences in Romantic Relationships

An evolutionary approach to gender differences in romantic relationships has pervaded the scientific literature, a trend mirrored in popular culture by Mars-Venus stereotyping. Three studies tested the accuracy of the popular notion that gender differences would emerge for the behaviors women and men want and receive from romantic partners in a sample of 375 students at a southeastern U.S. public university. Across the three studies, only one stable and robust gender difference emerged (desires regarding relationship support), as did several unstable gender differences. However, gender-role identity significantly accounted for nearly half of the variance in this one stable gender difference, challenging the viability of some evolutionary conceptualizations of gender differences and instead providing support for social constructionist and feminist perspectives.     

If they were to vote, they would vote for us

In two field studies, we examined whether voters overestimate support for their political party among nonvoters. In Study 1, voters estimated the percentage of votes their party would receive in an upcoming election, and this percentage increased when voters estimated the percentage of votes their party would receive if nonvoters also were to vote. In Study 2, participants overestimated support for their party even when we made them explicitly aware of current levels of this support by presenting them with poll-based forecasts of election results. Furthermore, Study 2 demonstrated that commitment to vote for a specific party predicted the degree of overestimation. Our results imply that highly committed voters are particularly likely to project support for their party onto nonvoters. Implications for the literature on social projection and social identity are discussed.     

The impact of gender on the assessment of body checking behavior

Body checking includes any behavior aimed at global or specific evaluations of appearance characteristics. Men and women are believed to express these behaviors differently, possibly reflecting different socialization. However, there has been no empirical test of the impact of gender on body checking. A total of 1024 male and female college students completed two measures of body checking, the Body Checking Questionnaire and the Male Body Checking Questionnaire. Using multiple group confirmatory factor analysis, differential item functioning (DIF) was explored in a composite of these measures. Two global latent factors were identified (female and male body checking severity), and there were expected gender differences in these factors even after controlling for DIF. Ten items were found to be unbiased by gender and provide a suitable brief measure of body checking for mixed gender research. Practical applications for body checking assessment and theoretical implications are discussed.     

A Moral‐Existential Account of the Psychological Factors Fostering Intergroup Conflict

We combine ideas from terror management and moral foundations theories to analyze the role of existential and moral concerns in the creation and escalation of intergroup conflict. We argue that moral values, as important components of cultural worldviews, serve to buffer existential anxiety. Perceived threats to one’s moral values thus are capable of inducing existential anxiety and unleashing strong moral emotions, creating the psychological impetus for intergroup conflict and violence. We review evidence that threats to the five core moral intuitions posited by moral foundations theory (harm/care, fairness/reciprocity, ingroup/loyalty, authority/respect, and purity/ sanctity) are associated with existential anxiety and that this contributes to intergroup strife and violence. Moral and existential concerns combine to create a vicious feedback loop that leads to self‐perpetuating spirals of violence, which helps explain the intractability of many real‐life conflicts.     

Disrupting the flow: How brief silences in group conversations affect social needs

We all know the awkward feeling when a conversation is disrupted by a brief silence. This paper studies why such moments can be unsettling. We suggest that silences are particularly disturbing if they disrupt the conversational flow. In two experiments we examined the effects of a single brief instance of silence on social needs, perceived consensus, emotions, and rejection. Study 1 demonstrated that fluent conversations are associated with feelings of belonging, self-esteem, and social validation. If a brief silence disrupts this fluency, negative emotions and feelings of rejection arise. Study 2 replicated these effects in a more realistic setting, and showed that the effects of a brief silence are considerable despite participants' unawareness of the silence. Together, results show that conversational flow induces a sense of belonging and positive self-esteem. Moreover, this research suggests an implicit route to social validation, in which consensus is inferred from fluent group conversation.
