Adults' representations of division facts: a consequence of learning history?

There has been a recent increase in the study of adults' performance on simple division problems. Researchers up to now have focused on the relationship between multiplication and division and have found that multiplication often has a mediating role in the solution of division problems (Campbell, 1997, 1999; LeFevre & Morris, 1999; Mauro, LeFevre, & Morris, 2002). In this study, division was exclusively examined to determine the strategies that are used to solve these problems and to identify factors relating to particular strategy use. Thirty-two participants were asked to solve two sets of 64 simple division problems (from 4 divided by 2 to 81 divided by 9) and error, latency, and strategy report data were collected. Fewer errors were made on easy problems, which were also solved more quickly than difficult problems. Participants used retrieval, multiplication, and other strategies to solve the problems and tended to use retrieval more on easy than difficult problems and used multiplication more on difficult problems than easy problems. Unexpected age differences in strategy use were also found. Older participants tended to rely more heavily on retrieval than younger participants. These results suggest that older participants may have stronger representations for simple division problems than younger participants.     

Transformational Travel for Seminarians: Reading James in Haiti

How will we teach the Bible in the twenty‐first century? This essay is intended to contribute to that larger discussion in three ways: after a brief introduction, I will, first, state some general working assumptions about the present situation of the church and about teaching the New Testament in the context of a seminary or divinity school; second, I will describe the course “Reading James in Haiti” which I designed and taught in the Spring of 1902; finally, and much more briefly, I will comment on the implications of transformational travel experiences like this one for the ability of seminarians to understand New Testament texts more deeply than the classroom setting allows.     

Maternal self‐efficacy beliefs,competence in parenting,and toddlers' behavior and developmental status

This study was designed to examine parenting self‐efficacy beliefs as correlates of mothers' competence in parenting toddlers and as predictors of toddlers' behavior and development. Sixty‐eight predominantly middle‐class mother–toddler pairs participated in this study. Mothers completed questionnaires, toddlers were administered the Bayley Scales of Infant Development (BSID‐II), and each dyad participated in the Crowell Procedure, which is designed to observe parent and toddler behaviors in a semistructured laboratory context. Although domain‐general and domain‐specific parenting self‐efficacy beliefs were not associated with parenting competence, domain‐specific beliefs were significantly related to toddlers' scores on the Mental Scale of the BSID‐II and several behaviors observed during the Crowell Procedure (Affection Towards Mother, Avoidance of Mother, Compliance, Enthusiasm, and Negativity). Implications of the findings are discussed. ©2003 Michigan Association for Infant Mental Health.     

Adolescent Ego-Development Trajectories and Young Adult Relationship Outcomes

Adolescent ego-development trajectories were related to close-relationship outcomes in young adulthood. An adolescent sample completed annual measures of ego development from ages 14 through 17. The authors theoretically determined and empirically traced five ego-development trajectories reflecting stability or change. At age 25, the sample completed a close-relationship interview and consented for two peers to rate the participants'ego resiliency and hostility. Participants who followed the profound-arrest trajectory in adolescence reported more mundane sharing of experiences, more impulsive or egocentric conflict-resolution tactics, and less mature interpersonal understanding in their young adult relationships, and their young adult peers described these participants as more hostile. Participants who attained or maintained higher levels of ego development in adolescence reported more complex sharing of experiences, more collaborative conflict-resolution strategies, and greater interpersonal understanding, and their young adult peers rated them as less hostile and as more flexible.     

The Role of School-based Group Mentoring in Promoting Resilience among Vulnerable High School Students

This study examined the role of participation in a year-long school-based group mentoring program, Project Arrive (PA), on increasing resilience during the first year of high school among students identified as being at high risk for school dropout. Participants were 114, ninth grade students taking part in one of 32 PA mentoring groups, and 71 statistically matched comparison students (53% male, 75% eligible for free/reduced-price lunch, 62% Latinx). Using a propensity score with inverse probability of treatment weighting (IPTW) to reduce selection bias, and a multi-level model to account for non-independence of data within mentoring groups, we examined changes from pre-test to program exit on seven external resilience resources (developmental supports and opportunities) and four internal resilience assets (personal strengths). At program exit, PA participants had higher adjusted means than comparisons on six external resources, including school support, school belonging, school meaningful participation, peer caring relationships, prosocial peers, and home meaningful participation. PA participants also had higher adjusted means on one internal asset, problem solving. Results point to the promise of group mentoring as an approach for increasing resilience among academically vulnerable adolescents.     

Creative Fixation is No Laughing Matter: The Effects of Funny and Unfunny Examples on Humor Production

How do people come up with humorous ideas? In creative cognition research, exposure to good examples sometimes causes fixation (people get “stuck” on the examples) but other times sparks inspiration (people's responses are more creative). The present research examined the effects of funny and unfunny examples on joke production. A sample of 175 adults read scenarios that they completed with funny responses. All participants were instructed to be funny, but before responding they read (a) funny responses as examples of good responses to emulate, (b) unfunny responses as examples of poor responses to avoid, or (c) no examples. The participants’ own responses were rated for funniness and for similarity to the example responses, and response times were recorded. Reading either funny or unfunny examples, compared to no examples, caused people to come up with funnier jokes. Similarity to the examples was low in all conditions, so fixation was relatively modest, but people who saw unfunny examples spent more time coming up with their responses. Taken together, the findings support the growing literature showing that examples are often inspiring rather than constraining, and they imply that good and bad examples spark creative thought via different paths.
