Retelling urban legends

We explored factors influencing the retelling of urban legends. As predicted by prior work, people retold truthful and scary stories. But people also retold well-known stories. This contrasts with the expectation that people would not pass on a story that everyone already knew. Also as predicted by prior work, repeating a story increased its credibility. But repeating also increased a story's importance, scariness, and likelihood of retelling. In general, contextualizing a story and increasing the number of details did not affect the likelihood of retelling a story. The exception was that details increased the likelihood of retelling a newly heard story. However, if people read a story with context or details, more contextual elements and details were included in their retellings. At the same time, people confabulated details to an equal degree no matter what type of embellishments they had read.     

The effect of working memory capacity on conflict monitoring

The conflict adaptation effect, a reduced interference effect upon the detection of a conflict signal (e.g., following an incongruent trial), has been interpreted as evidence for active regulation of top-down cognitive control. We hypothesized that the extent of conflict adaptation should be related to individuals' working memory capacity (WMC), which has been repeatedly demonstrated to reflect the level of cognitive control. Using the Simon task, in Experiment 1, we quantified the conflict adaptation ratio (CAR) transiently as the ratio of the conflict effect following an incongruent trial to the conflict effect following a congruent trial, controlling for the reaction time that often correlates with WMC. We observed that the CAR varied from highly negative with low WMC scores to near-zero with high WMC scores. This result suggests that high WMC individuals, when detecting conflict, adjust the level of cognitive control optimally so that their performance is less susceptible to the presence of a distractor. In Experiment 2, we quantified the CAR in a sustained manner as the ratio of the conflict effect from predominantly incongruent blocks to the conflict effect from predominantly congruent blocks. Again, the CAR varied from negative to zero as WMC increased. These results suggest that WMC may reflect, in addition to the ability to maintain a level of control, the ability to adjust the level of control appropriately to the contextual demands.     

Older adults catch up to younger adults on a learning and memory task that involves collaborative social interaction

Learning and memory abilities tend to decline as people age. The current study examines the question of whether a learning situation that emphasises collaborative social interaction might help older persons overcome age-related learning and memory changes and thus perform similarly to younger persons. Younger and Older participants (n = 34 in each group) completed the Barrier Task (BT), a game-like social interaction where partners work together to develop labels for a set of abstract tangrams. Participants were also administered standard clinical neuropsychological measures of memory, on which the Older group showed expected inferiority to the Younger group. On the BT, the Older group performed less well than the Younger group early on, but as the task progressed, the performance of the Older group caught up and became statistically indistinguishable from that of the Younger group. These results can be taken to suggest that a learning milieu characterised by collaborative social interaction can attenuate some of the typical memory disadvantages associated with being older.     

How the Thatcher illusion reveals evolutionary differences in the face processing of primates

Face recognition in humans is a complex cognitive skill that requires sensitivity to unique configurations of eyes, mouth, and other facial features. The Thatcher illusion has been used to demonstrate the importance of orientation when processing configural information within faces. Transforming an upright face so that the eyes and mouth are inverted renders the face grotesque; however, when this “Thatcherized” face is inverted, the effect disappears. Due to the use of primate models in social cognition research, it is important to determine the extent to which specialized cognitive functions like face processing occur across species. To date, the Thatcher illusion has been explored in only a few species with mixed results. Here, we used computerized tasks to examine whether nonhuman primates perceive the Thatcher illusion. Chimpanzees and rhesus monkeys were required to discriminate between Thatcherized and unaltered faces presented upright and inverted. Our results confirm that chimpanzees perceived the Thatcher illusion, but rhesus monkeys did not, suggesting species differences in the importance of configural information in face processing. Three further experiments were conducted to understand why our results differed from previously published accounts of the Thatcher illusion in rhesus monkeys.     

Some Historical Conditions of Narrative Work

Written to honor the immense contribution of Michael White as a leader in the development of narrative therapy, this historical essay contrasts the origins of psychoanalysis, family therapy and narrative therapy. Changes in the understanding of therapeutic strategies, methods of training and supervision, styles of leadership, the involvement of audiences in the therapeutic and training processes, and conceptions of the nature of the mind are described. A style of direct demonstration of methods, especially of the formulation of questions, is important in narrative work. The central master-role of the therapist in analysis and family therapy is replaced in narrative work by eliciting local knowledge, and the recruitment of audiences to the work. This is consistent with narrative therapy's "de-centered" image of the therapist.     

The impact of family and peer differentiation levels on adolescent psychosocial development and problematic behaviors

This study examined the impact of family differentiation and peer differentiation levels on adolescent problematic behaviors and psychosocial maturity. Differentiation levels were assessed dyadically in both the family and peer systems. Results revealed family differentiation to be the sole predictor of adolescent problematic behavior. Additional regression analysis indicated that peer differentiation was a significant predictor of psychosocial maturity, along with the significant impact of adolescent gender and age. Family X Peer interaction terms were not significant predictors of either adolescent personal adjustment variable. Results, whichdisplay both consistencies and variations with the findings of previous research, are discussed in terms of their clinical implications.Salary and support provided in part by grants from The Kettering Fund (OSURF #727033) and by The Ohio State University (OSURF #221424 and OSURF #241501).     

Beyond home-based family intervention: A multi-family approach toward change

A growing specialty area in the mental health field involves working with emotionally disturbed youth and families-at-risk by providing services in the context of the home environment. A review of the literature provides documentation for family systems, social learning, and ecological interventions with at-risk families receiving home-based intervention but there is an absence of material on the use of multi-family groups with this population. The purpose of this article is to outline the implementation of a multi-family therapy (MFT) component for home-based programs serving at-risk families. Advantages and disadvantages when using MFT are also addressed.The authors are grateful to Linda Pannell for her helpful comments on drafts of this article.

Why do pictures produce priming on the word-fragment completion test? A study of encoding and retrieval factors

Three experiments examined why pictures produce priming on the word-fragment completion test, despite the fact that there is no match between the physical features of the picture and the word fragment. Pictures and words were presented as primes, and performance on the word-fragment completion test was measured; encoding and retrieval conditions were varied. Experi-ments 1 and 2 examined the role of picture labeling by increasing the presentation rate and by introducing a shadowing task during encoding; labeling appears to play a role in priming. In Experiment 3, the word fragments were presented for 500 msec, and subjects were required to provide a solution immediately. Word priming was unaffected, but picture priming was elimi-nated, suggesting that word fragments enable efficient recovery of perceptually similar primes (i.e., words), but slower and less direct recovery of conceptually similar but physically dissimilar
