Inference suppression and semantic memory retrieval: Every counterexample counts

Reasoning with conditionals involving causal content is known to be affected by retrieval of counterexamples from semantic memory. In this study we examined the characteristics of this search process in everyday conditional reasoning. In Experiment 1 we manipulated the number (zero to four) of explicitly presented counterexamples (alternative causes or disabling conditions) for causal conditionals. In Experiment 2, using a generation pretest, we measured the number of counterexamples participants could retrieve for a set of causal conditionals. One month after the pretest, participants were presented a reasoning task with the same conditionals. The experiments indicated that acceptance of modus ponens linearly decreased with every additionally retrieved disabler, whereas affirmation of the consequent acceptance linearly decreased as a function of the number of retrieved alternatives. Results for denial of the antecedent and modus tollens were less clear. The findings show that the search process does not necessarily stop after retrieval of a single counterexample and that every additional counterexample has an impact on the inference acceptance.     

Optimizing Contingency Management With Methamphetamine-Using Men Who Have Sex With Men

Among men who have sex with men (MSM), methamphetamine use is associated with multiple, overlapping syndemic conditions including increased risk for HIV seroconversion and onward HIV transmission. Contingency management (CM) is an evidence-based behavioral intervention implemented to curb methamphetamine use and optimize HIV/AIDS prevention among MSM in San Francisco since 2003. We conducted a program evaluation to document the evolution of this 12-week CM program to include delivery of brief, individual counseling incorporating motivational interviewing and behavioral skills. A drop-in group delivered concurrently with CM urine-screening visits also provides peer support as well as referrals for other social and medical services. From December 2011–October 2013, a total of 131 clients enrolled in the CM program and provided a median of 22 urine samples (Interquartile Range = 10–34) that were nonreactive for methamphetamine. Findings support the feasibility and acceptability of integrating individual and group counseling with community-based CM for methamphetamine-using MSM.     

What is the Impact of Placement Type on Educational and Health Outcomes of Unaccompanied Refugee Minors? A Systematic Review of the Evidence

Record numbers of unaccompanied refugee minors have been arriving in high-income countries since 2015. Child welfare agencies and non-governmental organisations tasked with providing services have struggled to cope with demands on their services as a result. Despite this, there is little research on how best to meet their needs and in particular what services can mitigate the psychological difficulties they face. As a result, the evidence base for social services for refugee children remains very limited. This paper is a systematic review and meta-analysis of the evidence on the relationship between care placement type and the educational, mental health and physical health outcomes of unaccompanied refugee minors. We searched ten databases and identified 3877 citations which were screened for inclusion. Nine studies were included in the final review, with seven included in the meta-analysis. Eight studies examined the link between accommodation type and mental health outcomes, and two analysed the relationship between accommodation type and education. There were no studies looking at physical health outcomes. Included studies suggest that foster care and placements that are culturally sensitive may be associated with better mental health outcomes. This review highlights the paucity of research on the impact of services provided by child welfare agencies and non-governmental organisations.     

Hurry up! The role of supervisors’ time urgency and self‐perceived status for autocratic leadership and subordinates’ well‐being

This study examines the connections among supervisors’ time urgency, their leadership behavior, and subordinate outcomes. Integrating cognitive perspectives on time urgency with contemporary thinking on the psychological experience of status, we reason that supervisors’ time‐urgent personality relates positively with their autocratic leadership behavior, and we cast supervisors’ self‐perceived status as a moderator of this linkage. Moreover, we enrich this leader‐centric perspective with a complementary, more follower‐centric view, recognizing that the consequences of supervisors’ time urgency likely extend beyond their own behavior to indirectly affect their subordinates’ well‐being at work. We tested our hypotheses using a field sample of 60 supervisors and 277 of their subordinates. Results indicate that (a) supervisors with higher time urgency are more likely to exhibit autocratic leadership behavior when they also perceive themselves as having relatively high status among subordinates, but not when perceiving lower status, and (b) supervisors’ time urgency exhibits a conditional indirect effect (via autocratic leadership) on subordinates’ work stress and time pressure experiences. Hence, this study illustrates an important boundary condition for the consequences of supervisors’ time urgency, and it demonstrates that this personality characteristic not only shapes supervisors’ leadership behavior but also affects the subordinates they are charged with leading.     

Inferring Others' Hidden Thoughts: Smart Guesses in a Low Diagnostic World

People are biased toward believing that what others say is what they truly think. This effect, known as the truth bias, has often been characterized as a judgmental error that impedes accuracy. We consider an alternative view: that it reflects the use of contextual information to make the best guess when the currently available information has low diagnosticity. Participants learnt the diagnostic value of four cues, which were present during truthful statements between 20% and 80% of the time. Afterwards, participants were given contextual information: either that most people would lie or that most would tell the truth. We found that people were biased in the direction of the context information when the individuating behavioral cues were nondiagnostic. As the individuating cues became more diagnostic, context had less to no effect. We conclude that more general context information is used to make an informed judgment when other individuating cues are absent. That is, the truth bias reflects a smart guess in a low diagnostic world. Copyright © 2015 John Wiley & Sons, Ltd.     

Perceptions of injustice in intercultural relations

Perceptions of injustice are likely to occur in intercultural relations because cultures often define justice and its implementation differently. This article reviews factors and processes that are unique to intercultural relations and that may give rise to feelings of injustice during intercultural interactions. Antecedents that can trigger a sense of injustice with regard to distributive, procedural, and retributive justice are reviewed. The consequences of perceived injustice are also analyzed. The implications of our analysis for research and practice are discussed.
