Context-dependent memory for meaningful material: information for students

Context-dependency effects on memory for lists of unrelated words have been shown more often with recall than with recognition. Context dependency for meaningful text material was examined using two standard academic testing techniques: short answer (recall) and multiple choice (recognition). Forty participants read an article in either silent or noisy conditions; their reading comprehension was assessed with both types of test under silent or noisy conditions. Both tests showed context-dependency effects in which performance was better in the matching conditions (silent study/silent test and noisy study/noisy test) than in the mismatching conditions (silent study/noisy test and noisy study/silent test). Context cues appear to be important in the retrieval of newly learned meaningful information. An academic application is that students may perform better on exams by studying in silence.

The orientation of young and older adults' mental representations of their home town with familiar and new landmarks

Familiarity with an environment produces refined mental representations in adults of all ages, but it is not clear whether these representations tend to have a north-up orientation and whether familiarity facilitates the learning of new spatial information, especially in ageing. Thirty-two young and 32 older adults studied a map of their home town that included familiar and new fictitious landmarks, then performed pointing tasks, some aligned with the cardinal points south–north (SN), and others counter-aligned, north–south (NS). A measure of visuo-spatial working memory (VSWM) and a questionnaire on pleasure in exploring were also administered. The results showed that performance was better when pointing SN than NS (alignment effect), whereas pointing performance for familiar landmarks was similar for SN and NS alignments (no alignment effect). No interaction involving age was found. VSWM emerged as a significant predictor of pointing performance. Spatial mental representations of familiar environments are elaborate and flexible as regards familiar landmarks, in both young and older adults; and a familiar layout does not seem to enhance older adults' spatial memory as regards new landmarks.     

Children's reading of words, pseudohomophones, and other nonwords

In Experiment 1 children aged 8-9 and 9-10 years were tested for neighbourhood and pseudohomophone effects in nonword reading. Neighbourhood effects ( N effects) were robust irrespective of group or type of nonword. Pseudohomophones were read more accurately than other nonwords but this finding was robust only for the younger 8-9-year-olds. High-frequency words were read more accurately than low-frequency words, but the reverse applied to pseudohomophones based on high- and low-frequency words, although this was not robust. Error rates for the 9-10-year-olds in Experiment 1 were low, and so it was difficult to interpret the lack of a pseudohomophone advantage for reading nonwords in this age group. Experiment 2 was therefore carried out, which consisted of a replication of the first study with a further group of 9- 10-year-olds, but pronunciation latencies were measured, as well as accuracy. All the effects obtained in Experiment 1 were replicated but, in addition, an advantage for pseudohomophones in terms of pronunciation latencies was observed. The implications for accounts of reading development are discussed.

The Relation Between Maternal ADHD Symptoms &; Improvement in Child Behavior Following Brief Behavioral Parent Training is Mediated by Change in Negative Parenting

This study examined the extent to which maternal attention-deficit/hyperactivity disorder (ADHD) symptoms predict improvement in child behavior following brief behavioral parent training. Change in parenting was examined as a potential mediator of the negative relationship between maternal ADHD symptoms and improvement in child behavior. Seventy mothers of 6–10 year old children with ADHD underwent a comprehensive assessment of adult ADHD prior to participating in an abbreviated parent training program. Before and after treatment, parenting was assessed via maternal reports and observations and child disruptive behavior was measured via maternal report. Controlling for pre-treatment levels, maternal ADHD symptomatology predicted post-treatment child disruptive behavior problems. The relation between maternal ADHD symptomatology and improvement in child behavior was mediated by change in observed maternal negative parenting. This study replicated findings linking maternal ADHD symptoms with attenuated child improvement following parent training, and is the first to demonstrate that negative parenting at least partially explains this relationship. Innovative approaches combining evidence-based treatment for adult ADHD with parent training may therefore be necessary for families in which both the mother and child have ADHD. Larger-scale studies using a full evidence-based parent training program are needed to replicate these findings.
