What you know can hurt you: effects of age and prior knowledge on the accuracy of judgments of learning

How do aging and prior knowledge affect memory and metamemory? We explored this question in the context of a dual-process approach to Judgments of Learning (JOLs), which require people to predict their ability to remember information at a later time. Young and older adults (n = 36, mean ages = 20.2 & 73.1) studied the names of actors who were famous in the 1950s or 1990s, providing a JOL for each. Recognition memory for studied and unstudied actors was then assessed using a Recollect/Know/No-Memory (R/K/N) judgment task. Results showed that prior knowledge increased recollection in both age groups such that older adults recollected significantly more 1950s actors than younger adults. Also, for both age groups and both decades, actors judged R at test garnered significantly higher JOLs at study than actors judged K or N. However, while the young showed benefits of prior knowledge on relative JOL accuracy, older adults did not, showing lower levels of JOL accuracy for 1950s actors despite having higher recollection for, and knowledge about, those actors. Overall, the data suggest that prior knowledge can be a double-edged sword, increasing the availability of details that can support later recollection, but also increasing nondiagnostic feelings of familiarity that can reduce the accuracy of memory predictions.     

Epitaxial Ni-Al thin films on NaCl using a Ag buffer layer

Epitaxial nanoscale [001] films of Ni _x Al_100-x (x = 62.5) have been prepared by physical vapour deposition on to a thin film of Ag [001] on NaCl (001) faces with occasional hillocks. The Ag film contains numerous dislocations and stacking faults and has a rms surface roughness of 2 nm. The Ni-Al film is ordered in the B2 structure and reveals many dislocations as well as antiphase boundaries between ordered domains. The formation of subgrains in the Ni-Al film results in severe height variations up to 30 nm across the surface. A cross-sectional model for the growth of both films is presented.     

Fluency,Familiarity, Aging,and the Illusion of Truth

ABSTRACT

Research has shown that repeated statements are rated as more credible than new statements. However, little research has examined whether such “illusions of truth” can be produced by contextual (nonmnemonic) influences, or compared to the magnitude of these illusions in younger and older adults. In two experiments, we examined how manipulations of perceptual and conceptual fluency influenced truth and familiarity ratings made by young and older adults. Stimuli were claims about companies or products varying in normative familiarity. Results showed only small effects of perceptual fluency on rated truth or familiarity. In contrast, manipulating conceptual fluency via semantic/textual context had much larger effects on rated truth and familiarity, with the effects modulated by normative company familiarity such that fluency biases were larger for lesser-known companies. In both experiments, young and older adults were equally susceptible to fluency-based biases.     

Mother-child play and emerging social behaviors among infants from maltreating families

Mother-child play of 12-month-old infants (N=130) from maltreating (N=78) and non-maltreating (N=52) families was analyzed as a context that integrates infants' developing social and cognitive skills. Play was coded from semistructured and unstructured play paradigms. No group differences were found in infants' play maturity. Infants from abusing families demonstrated more imitative play than infants from non-maltreating families, and engaged in less independent play than infants from both neglecting and non-maltreating families, suggesting a delay in emerging social behaviors. Mothers from abusing and non-maltreating families differed in attention directing behaviors. Maternal behaviors predicted child play style variables, but did not mediate the effects of maltreatment. Findings discuss the influence of an early maltreating environment upon the development of the emergent self. Implications for early intervention are underscored.     

Effect of maltreatment on preschoolers' narrative representations of responses to relieve distress and of role reversal

A total of 80 low-socioeconomic status maltreated preschoolers were contrasted with 27 nonmaltreated preschoolers on their narrative representations. The children completed story stems, taken from the MacArthur Story-Stem Battery (MSSB; I. Bretherton, D. Oppenheim, H. Buchsbaum, R. N. Emde, & the MacArthur Narrative Group, 1990), that introduced stressful family situations. Using the MacArthur narrative coding manual (J. Robinson, L. Mantz-Simmons, J. Macfie, & the MacArthur Narrative Group, 1992), coders rated portrayals of parental and child character responses, as well as participant responses, to relieve children's distress. They also rated role reversal (children caretaking their parents) from the narrative emotion coding manual (S. L. Warren, L. Mantz-Simmons, & R. N. Emde, 1993). Maltreated preschoolers portrayed parents and children as responding less often--yet themselves as stepping into the story more often to relieve children's distress--than did nonmaltreated preschoolers. Abused children (sexually, physically, or both) portrayed the most participant responses, and neglected children (with no abuse) portrayed the fewest child responses. Role reversal was associated with physical abuse.     

Applying Skill-Based Curriculum to Teach Feedback in Groups: An Evaluation Study

Group counseling theory and empirical research indicate that interpersonal feedback is an important element that can lead to insight and change in group members. Yet, managing interpersonal feedback is a difficult skill for novice group leaders to learn. This article examines (a) the role of feedback in counseling groups; (b) the implementation of a skill-based training program to teach novice group counselors how to give, receive, and facilitate interpersonal feedback; and (c) students' evaluation of such a program in which they participated. Recommendations are made to practitioners for incorporating feedback into counseling, and for counselor educators regarding the teaching of the intervention.

Study Preregistration: An Evaluation of a Method for Transparent Reporting

Study preregistration promotes transparency in scientific research by making a clear distinction between a priori and post hoc procedures or analyses. Management and applied psychology have not embraced preregistration in the way other closely related social science fields have. There may be concerns that preregistration does not add value and prevents exploratory data analyses. Using a mixed-method approach, in Study 1, we compared published preregistered samples against published non-preregistered samples. We found that preregistration effectively facilitated more transparent reporting based on criteria (i.e., confirmed hypotheses and a priori analysis plans). Moreover, consistent with concerns that the published literature contains elevated type I error rates, preregistered samples had fewer statistically significant results (48%) than non-preregistered samples (66%). To learn about the perceived advantages, disadvantages, and misconceptions of study preregistration, in Study 2, we surveyed authors of preregistered studies and authors who had never preregistered a study. Participants in both samples had positive inclinations towards preregistration yet expressed concerns about the process. We conclude with a review of best practices for management and applied psychology stakeholders.

     

Dissociation of Processes Underlying Spatial S-R Compatibility: Evidence for the Independent Influence of What and Where

The process-dissociation procedure was used to estimate the influence of spatial and form-based processing in the Simon task. Subjects made manual (left/right) responses to the direction of arrows (> or <) presented to the left or right of fixation. Manipulating the proportion of incongruent trails (e.g., a right-pointing arrow presented to the left of fixation) affected both the size and direction of the Simon effect. To account for this pattern of data, we compared process estimates based on three possible relationships between spatial and form-based processing: independence, redundancy, and exclusivity. The independence model provided the best account of the data. Most telling was that independent form-based estimates were superior at predicting observed performance on arrows presented at fixation and did so consistently across conditions (r′s > .80). The results provide evidence that the form ("what") and spatial location ("where") of a single stimulus can have functionally independent effects on performance. They also indicate the existence of two kinds of automaticity—an associative ("implicit learning") component that reflects prior S-R mappings and a nonassociative component that reflects the correspondence between stimulus and response codes.
