Effects of mothers’ conversation style and receipt of misinformation on children's event reports

Can memory sharing conversations with mothers lead to errors in children's event memory when mothers are exposed to misinformation about what their children experienced and does this effect vary as a function of maternal memory-sharing style? Mothers were exposed to a false suggestion about a non-shared event and then discussed that event with their children. When later interviewed, those children whose mothers were provided this misinformation were likely to wrongly report experiencing activities consistent with the maternal suggestion and embellish their reports of these activities with elaborative detail. Moreover, children whose mothers spoke in a highly elaborative manner were more likely to recall occurrences in line with the maternal suggestion and provided more fictitious narrative detail describing non-occurring-but-suggested information than did children whose mothers used a less elaborative style. These findings suggest that when mothers hold false beliefs about a non-shared event, an elaborative maternal style is associated with an increase in children's false reports reflecting maternal beliefs.     

Dichotic listening performances in the follow-up of Landau and Kleffner syndrome

Abstract

In the follow-up study of 4 children with acquired epileptic aphasia or Landau and Kleffner syndrome, dichotic listening studies evidenced a unilateral ear extinction. In the four cases, the dichotic extinction was contralateral to the temporal cortex involved in the generation of epileptic discharges during the active period of epilepsy. This pattern of dichotic performances persisted several years after the complete recovery from epilepsy and EEG normalization. The long-lasting dichotic extinction revealed a permanent dysfunction in the temporal auditory system that may be a consequence of the presence of an active epileptogenic focus during the critical period of functional differentiation of the temporal cortex.     

Seeing Things Unseen: Fantasy Beliefs and False Reports

Whereas past research has demonstrated that children's beliefs about the real world can influence their memory for events, the role of fantasy beliefs in children's recall remains largely unexplored. We examine this topic in 5- and 6-year-olds by focusing on how belief in a familiar fantasy figure, namely the Tooth Fairy, is related to children's memory for their most recent primary tooth loss. Although children who fully believed in the reality of the Tooth Fairy provided more voluminous and complex accounts than those with less strong beliefs, they also provided the most fictitious reports, frequently characterized by claims of hearing or seeing the Tooth Fairy. Belief in the Tooth Fairy did not affect the accuracy of children's reports of the mundane elements of their tooth loss, and many fantastic claims were linked to real events. Exposure to seemingly tangible evidence of the Tooth Fairy's existence was associated with the provision of fantastic claims.     

Testing take-the-best in new and changing environments

Take-the-best is a decision-making strategy that chooses between alternatives, by searching the cues representing the alternatives in order of cue validity, and choosing the alternative with the first discriminating cue. Theoretical support for take-the-best comes from the “fast and frugal” approach to modeling cognition, which assumes decision-making strategies need to be fast to cope with a competitive world, and be simple to be robust to uncertainty and environmental change. We contribute to the empirical evaluation of take-the-best in two ways. First, we generate four new environments—involving bridge lengths, hamburger prices, theme park attendances, and US university rankings—supplementing the relatively limited number of naturally cue-based environments previously considered. We find that take-the-best is as accurate as rival decision strategies that use all of the available cues. Secondly, we develop 19 new data sets characterizing the change in cities and their populations in four countries. We find that take-the-best maintains its accuracy and limited search as the environments change, even if cue validities learned in one environment are used to make decisions in another. Once again, we find that take-the-best is as accurate as rival strategies that use all of the cues. We conclude that these new evaluations support the theoretical claims of the accuracy, frugality, and robustness for take-the-best, and that the new data sets provide a valuable resource for the more general study of the relationship between effective decision-making strategies and the environments in which they operate.     

Working memory outcomes following unilateral arterial ischemic stroke in childhood

There is a dearth of research examining working memory (WM) following pediatric arterial ischemic stroke (AIS). This study assesses the WM patterns of 32 children, aged 6 to 14 years, with a history of unilateral AIS and 32 controls using a paradigm based on Baddeley and Hitch’s multi-component WM model. The results indicate compromised WM in children with AIS relative to controls and parent reports confirm higher rates of dysfunction. Supplementary analyses of impairment confirm higher rates in children with AIS, ranging from 31.25% to 38.70% on performance-based measures and 50.00% on parent reports, compared to 0.00% to 21.88% on performance-based measures in controls and 15.63% on parent reports. Continual follow-up is recommended given that a subset of children with stroke appear to be at risk for WM impairment. Moreover, the subtle nature of WM challenges experienced by many children who have experienced a stroke increases the likelihood that WM impairment could go undetected. The long-term trajectories of WM in the pediatric stroke population remains unknown and future studies are needed to track changes in WM functioning over time.     

Increasing Class Participation in College Classrooms with the Good Behavior Game

Participation in college classrooms remains low, despite evidence that increased participation contributes to better grades. Incorporating active student educational strategies may help combat poor participation. The Good Behavior Game is a tool for improving various behaviors of children and adolescents in schools. However, strategies similar to the Good Behavior Game have not yet been assessed with young adults in college classrooms. We used an alternating treatments design to evaluate effects of a modified version of the Good Behavior Game on participation across three introductory psychology courses at a public university. We collected baseline data on class participation and then compared two variations of the Good Behavior Game—one included delivering a preferred reward to individuals on the winning team and one did not include a reward. Incorporating components of the Good Behavior Game increased class participation with and without a preferred reward, relative to baseline. Students reported preferring the game with a reward relative to the game with no reward and not playing the game. Because class participation has been correlated with better course grades, incorporating features of the Good Behavior Game may be a feasible approach for improving college students’ education.     

The Long-Term Impact of Family Routines and Parental Knowledge on Alcohol Use and Health Behaviors: Results from a 14 Year Follow-Up

Previous research has found significant associations between family routines (e.g., time shared and family meals), parenting characteristics, and later adolescent health behaviors. In general, greater family interactions, parental monitoring, and more optimal parenting style have been associated with less alcohol use during adolescence. We expanded upon this work by examining effects of family and parenting characteristics on alcohol use and health behaviors during young adulthood. We also followed tenets of the Contextual Model of Parenting by examining the moderating effects of parenting style on the associations between parent/family practices and outcomes. Data came from the National Longitudinal Survey of Youth 1997. A total of 5419 youth were surveyed at 12–14 years of age, and then annually for the next 14 years; 4565 were surveyed at a 10 year follow-up and 4539 were examined at the 14 year follow-up (84% retention). Multivariate models, controlling for sex and race/ethnicity, indicated that, in general, family routines and parental knowledge in early adolescence were associated with healthier behaviors at both the 10-year and 14-follow-ups. Results also showed that the protective effects of parental knowledge and family routines were strongest in families characterized by and authoritative parenting style.     

Heterosexual, lesbian, and gay male relationships: a comparison of couples in 1975 and 2000

This study examined the differences among lesbians, gay men, and heterosexuals at two points in time (1975 and 2000) using responses of 6,864 participants from two archival data sets. Groups were compared on variables representing equality of behaviors between partners in seven realms: traditionally "feminine" housework, traditionally "masculine" housework, finances, support, communication, requesting/refusing sex, and decision-making. In addition, the current study compared monogamy agreements and monogamy behaviors reported by the two cohorts of couple types. Overall, the results indicate that on the equality variables, there have been many statistically significant behavioral shifts among the different sexual orientations across 25 years. In addition, all couple types reported substantially greater rates of monogamy in the year 2000 than in 1975. The present study has important clinical implications for therapists working with couples because it provides new baseline evidence regarding how couples now interact with one another (especially about monogamy) and how this has shifted over time. In addition, it elucidates the differences that still exist between different couple types, which could serve to inform couple therapists as they strive to become more culturally competent working with same-sex couples.     

False rumors and true belief: Memory processes underlying children’s errant reports of rumored events

Previous research has shown that overhearing an errant rumor—either from an adult or from peers—about an earlier experience can lead children to make detailed false reports. This study investigates the extent to which such accounts are driven by changes in children’s memory representations or merely social demands that encourage the reporting of rumored information. This was accomplished by (a) using a warning manipulation that eliminated social pressures to report an earlier heard rumor and (b) examining the qualitative characteristics of children’s false narratives of a rumored-but-nonexperienced event. Findings indicated that overheard rumors can induce sensory and contextual characteristics in memory that can lead children to develop genuine false beliefs in seeing rumored-but-nonexperienced occurrences. Such constructive tendencies were especially likely among 3- and 4-year-olds (relative to 5- and 6-year-olds) and when rumors were picked up from peers during natural social interactions (relative to when they were planted by an adult).     

The consistency of inconsistency in serial homicide: patterns of behavioural change across series

Linkage analysis is a crucial part of the investigative process when faced with a possible series of related offences. Establishing behavioural consistency (i.e., offender's behaviours consistently present across the series) is at the core of linkage. Recent empirical studies have found little evidence of consistency looking at either individual or groups of behaviours in serial homicide. It is argued that behavioural changes are rooted in the changing cognitive strategies that offenders use to reach their ultimate goal (i.e. the commission of multiple homicides). Factors that could account for these changes include learning, situational factors, loss of control, and changes in the offender's fantasy. Patterns of behavioural change have been identified in serial crimes, such as rape. However, no empirical studies have looked at patterns of behavioural change in serial homicide. The present study examined patterns of consistency and change using a combination of thematic and behavioural subgroup approaches that use Multidimensional Scaling. Thematic differentiation indicative of behavioural manifestations of cognitive strategies was found in all three examined subgroups: planning, wounding, and offender–victim interaction, and patterns of change within these subgroups provided support for the above theories. Looking at behavioural patterns rather than individual behaviours, may be a more fruitful way of examining consistency in serial homicide, and could have significant implications for linkage analysis.
