Spacing effects in recognition memory: When meaning matters

The present study showed that using incidental learning tasks promoting structural/perceptual processing of targets it is possible to obtain a reliable spacing effect for nonwords in a yes/no recognition memory task, whereas no spacing effect is detected for words. These data are, collectively, incompatible with current theories of spacing effects. A theoretical proposal to account for these findings is outlined.     

Emotional impacts of participation in an Australian national survey on mental health-related discrimination

Institutional Review Boards have expressed concern that research into sensitive topics such as mental disorder will cause participants undue distress. This study investigated the emotional responses of 5,220 Australians to a survey on mental-health-related discrimination. Participants were interviewed about their mental health and experiences of discrimination across 10 life domains and then the emotional impacts of the survey. Results suggested that a minority experienced a negative reaction (2.8% felt depressed, 5.3% distressed, 9.5% reported intrusion on privacy, 2.5% regretted participation) in contrast to 88% reporting positive experiences. A mental health problem was associated with both negative and positive reactions.     

Moderators of the Relationship Between Maternal Substance Abuse Symptoms and Preschool Children’s Behavioral Outcomes

While maternal substance use problems increase the likelihood of behavior problems in children, child outcomes are varied, leading to interest in understanding additional family factors that contribute to the development of behavior problems in children impacted by maternal substance abuse. The purpose of this study is to examine harsh parenting and family conflict as potential moderators of the relationship between symptoms of maternal substance use problems and child externalizing behavior problems. The non-clinical sample for this study included 250 low-income parents whose preschool age children were enrolled in Head Start programs in a Southern state. This study utilized data collected during two home visits, an average of 10 months apart, with data on family functioning and maternal symptoms of substance use problems collected at the first time point and child externalizing behavior collected at the second time point. Over one-third of the children (38.1 %) had clinically elevated externalizing behavior scores. We used regression analysis to examine whether harsh parenting or family conflict moderated the relationship between maternal substance use symptoms and child externalizing behavior. In this community sample, we found that in the absence of family risks related to harsh parenting and family conflict, maternal symptoms of substance use problems did not have a significant impact on child externalizing behavior in preschool children. However, when high levels of family conflict or harsh parenting were present, symptoms of maternal substance use problems increased the risk of externalizing behavior problems in children.     

An overview of the literature on female-perpetrated adult male sexual victimization

The rape of women has been an issue of concern in research literature for the past 40 years. Conversely, rape against men has only relatively recently received investigation. The current paper reviews the existing research literature regarding male rape and sexual assault, with particular emphasis on female perpetrated male sexual victimization. The review covers issues regarding biased legal definitions, rape myths, feminist theory, and stereotypical or negative beliefs; all of which create a problematic social environment for male victims of female perpetrated assault to report crimes. The review also discusses the prevalence of female perpetrated attacks against men, with evidence from self-reports by female sex offenders to highlight the existence of male sexual victimization and the aggressive manner in which the sexual activity is committed. The review concludes that male sexual victimization by women should be taken as seriously as that of women by men.     

Recurrence quantification analysis of eye movements

Recurrence quantification analysis (RQA) has been successfully used for describing dynamic systems that are too complex to be characterized adequately by standard methods in time series analysis. More recently, RQA has been used for analyzing the coordination of gaze patterns between cooperating individuals. Here, we extend RQA to the characterization of fixation sequences, and we show that the global and local temporal characteristics of fixation sequences can be captured by a small number of RQA measures that have a clear interpretation in this context. We applied RQA to the analysis of a study in which observers looked at different scenes under natural or gaze-contingent viewing conditions, and we found large differences in the RQA measures between the viewing conditions, indicating that RQA is a powerful new tool for the analysis of the temporal patterns of eye movement behavior.     

Semantic memory: A feature-based analysis and new norms for Italian

Semantic norms for properties produced by native speakers are valuable tools for researchers interested in the structure of semantic memory and in category-specific semantic deficits in individuals following brain damage. The aims of this study were threefold. First, we sought to extend existing semantic norms by adopting an empirical approach to category (Exp. 1) and concept (Exp. 2) selection, in order to obtain a more representative set of semantic memory features. Second, we extensively outlined a new set of semantic production norms collected from Italian native speakers for 120 artifactual and natural basic-level concepts, using numerous measures and statistics following a feature-listing task (Exp. 3b). Finally, we aimed to create a new publicly accessible database, since only a few existing databases are publicly available online.     

Enhanced Encoding of Nonverbal Cues Bipolar Illness in Males

Twenty-five affectively bipolar males were found to possess an enhanced ability to encode nonverbal cues when compared to matched controls. This ability was present during both manic and euthymic phases.     

Is Language Required to Represent Others’ Mental States? Evidence From Beliefs and Other Representations

An important part of our Theory of Mind—the ability to reason about other people's unobservable mental states—is the ability to attribute false beliefs to others. We investigated whether processing these false beliefs, as well as similar but nonmental representations, is reliant on language. Participants watched videos in which a protagonist hides a gift and either takes a photo of it or writes a text about its location before a second person inadvertently moves the present to a different location, thereby rendering the belief and either the photo or text false. At the same time, participants performed either a concurrent verbal interference task (rehearsing strings of digits) or a visual interference task (remembering a visual pattern). Results showed that performance on false belief trials did not decline under verbal interference relative to visual interference. We interpret these findings as further support for the view that language does not form an essential part of the process of reasoning online (“in the moment”) about false beliefs.
