Informational intra‐group influence: the effects of time pressure and group size

The judgments of groups have immense impact on our daily lives. This paper theorizes that three families of intra‐group influence affect the collective estimation process. These different forms of influence map to different levels of task demonstrability, or the extent to which correct answers are transparent to problem‐solvers. When demonstrability is low, group estimates are disproportionately influenced by proposals closer to the intra‐group mean (centrality). When demonstrability is high and groups are small, group decisions are disproportionately influenced by proposals closer to the correct answer (accuracy). Finally, when demonstrability is high and groups are larger, group decisions are disproportionately influenced by proposals offered by generally more accurate individuals across a set of judgments (expertise). Three laboratory studies support our predictions with regard to informational influence in cooperative groups. Copyright © 2006 John Wiley & Sons, Ltd.     

Pictorial superiority effects in oldest-old people

We examined memory for pictures and words in middle-age (45-59 years), young-old (60-74 years), old-old (75-89 years), and the oldest-old adults (90-97 years) in the Louisiana Healthy Aging Study. Stimulus items were presented and retention was tested in a blocked order where half of the participants studied 16 simple line drawings and the other half studied matching words during acquisition. Free recall and recognition followed. In the next acquisition/test block a new set of items was used where the stimulus format was changed relative to the first block. Results yielded pictorial superiority effects in both retention measures for all age groups. Follow-up analyses of clustering in free recall revealed that a greater number of categories were accessed (which reflects participants' retrieval plan) and more items were recalled per category (which reflects participants' encoding strategy) when pictures served as stimuli compared to words. Cognitive status and working memory span were correlated with picture and word recall. Regression analyses confirmed that these individual difference variables accounted for significant age-related variance in recall. These data strongly suggest that the oldest-old can utilise nonverbal memory codes to support long-term retention as effectively as do younger adults.     

Sex education attitudes and outcomes among North American women

Attitudes and outcomes of sex education received by North American women are examined via an Internet survey (N = 1,400). Mean age was 19.5, with 24% reporting one or more unplanned pregnancies. Women were more satisfied with sex education from informal sources than from parents, schools, and physicians. Those receiving sex education from parents or schools reported fewer pregnancies and abortions. In school, women receiving a combination of contraceptive and abstinence education and those receiving primarily abstinence education were least likely to experience unplanned pregnancy. Religious identification was significantly related to unplanned pregnancy and type of sex education received from parents. These factors seem to play a significant role in reducing unplanned pregnancy and abortion.

Intervention-based school psychology services: Training for child-level accountability; preparing for program-level accountability

This research evaluated the outcomes of a school psychology training practicum by replicating intervention-based service delivery procedures established in prior research. The key components include describing a service delivery model, teaching the model, deriving practice guidelines that fit the model, supporting trainees in carrying out the steps, and evaluating the outcomes. Procedures to determine outcomes were based on single-case design facets including accountability design (A-B), visual analysis of graphic data, and social validity ratings. Meta-analysis techniques included calculation of effect sizes and percent of nonoverlapping data (PND). Goal attainment scaling (GAS) also was used to summarize outcomes. The analyses indicated that the interventions led to positive changes for most children. For example, the median effect size was 1.42 across cases. Social validity evidence showed that consumers judged the outcomes positively. Achieving ideal baseline and technical adequacy checks (e.g., observer agreement, intervention adherence) represented challenges for many consultations. The contributions of the study include describing methods for child- and program-level accountability in training and areas for improvement including further supporting the completion of technical checks for intervention services.     

Executive functioning and health-related quality of life in pediatric sickle cell disease

Research consistently indicates that children with sickle cell disease (SCD) face multiple risk factors for neurocognitive impairment. Despite this, no empirical research to date has examined the impact of neurocognitive functioning on quality of life for this pediatric group. Thus, the current study aims to examine the relationship between executive functioning and quality of life in a sample of children with SCD and further explore psychosocial and family/caregiver resources as moderators of this relationship. A total of 45 children with SCD aged 8 to 16 years and their caregivers completed measures of quality of life, behavioral ratings of executive functioning, and psychosocial functioning. Hierarchical linear regression models were utilized to determine the impact of executive functioning on quality of life and further test the interaction effects of proposed moderating variables. Controlling for age, pain, and socioeconomic status (SES), executive functioning was found to significantly predict child- and parent-reported quality of life among youth with SCD. Psychosocial resources of the primary caregiver or family was not found to moderate the relationship between executive functioning and quality of life. These results provide the first empirical evidence that lower executive skills negatively predict quality of life for children with SCD, supporting clinical and research efforts which aim to establish efficacious interventions that target cognitive decrements within this pediatric population.     

Development of gaze aversion as disengagement from visual information

Older children, but not younger children, were found to look away more from the face of an interlocutor when answering difficult as opposed to easy questions. Similar results were found in earlier work with adults, who often avert their gaze during cognitively difficult tasks (A. M. Glenberg, J. L. Schroeder, & D. A. Robertson, 1998). Twenty-five 8-year-olds and 26 5-year-olds answered verbal reasoning and arithmetic questions of varying difficulty. The older children increased gaze aversion from the face of the adult questioner in response to both difficult verbal reasoning questions and difficult arithmetic questions. In contrast, younger children (5-year-olds) responded less consistently to cognitive difficulty. It is concluded that adultlike patterns of gaze aversion in response to cognitive difficulty are certainly acquired by 8 years of age. The implications of appropriate gaze aversion for children's management of cognitive processing resources are considered.     

Meet The Simpsons: top-down effects in face learning

We examined whether prior knowledge of a person affects the visual processes involved in learning a face. In two experiments, subjects were taught to associate human faces with characters they knew (from the TV show The Simpsons) or characters they did not (novel names). In each experiment, knowledge of the character predicted performance in a recognition memory test, relying only on old/new confidence ratings. In experiment 1, we established the technique and showed that there is a face-learning advantage for known people, even when face items are counterbalanced for familiarity across the experiment. In experiment 2 we replicated the effect in a setting which discouraged subjects from attending more to known than unknown people, and eliminated any visual association between face stimuli and a character from The Simpsons. We conclude that prior knowledge about a person can enhance learning of a new face.     

Psychosocial Impact of a Positive Gene Result for Asymptomatic Relatives at Risk of Hypertrophic Cardiomyopathy

Families with a history of hypertrophic cardiomyopathy (HCM) may be offered genetic testing in addition to clinical surveillance. Asymptomatic family members who are gene positive (silent gene carriers) represent a new group of “patients” who may not develop HCM, with little evidence available to assist clinical management. This study explored experiences of HCM genetic testing to identify potential benefits and harms. Thirty-two individuals previously offered genetic testing for HCM were recruited. Semi-structured interviews were conducted face-to-face or by phone, and transcribed audio-recordings were coded using framework analysis. Key themes were as follows: (1) helping the next generation, (2) misunderstanding risk, (3) discrepancy between actual/perceived impact. Participants described multiple psychological (shock, worry, uncertainty) and behavioural (career, sport, insurance, family planning) consequences, depending on perceived risk. Most considered only the benefits of genetic testing for children or grandchildren, but there were some cases of significant adverse impact. The interpretation of the HCM genetic test result is variable for silent gene carriers and can lead to psychological and behavioural changes. The impact of a positive gene result may be mitigated by increased clarity of the clinical consequences and efforts to ensure informed decision-making, highlighting even further the important role of cardiac genetic counselling.
