A comment on "Phonological recoding and reading."

Discusses 2 points raised in an article by L. X. McCusker et al (see record 1981-11846-001) on the role of phonological recoding in reading: (1) McCusker et al equated phonological mediation with the application of spelling–sound correspondence rules. The present study argues that such an assumption is not valid. (2) McCusker et al concluded that phonologically mediated semantic access decreases with reading skill. The present study argues that current data do not support this view. (14 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A responsive parenting intervention: The optimal timing across early childhood for impacting maternal behaviors and child outcomes.

This study examined the optimal timing (infancy, toddler-preschool, or both) for facilitating responsive parenting and the intervention effects on maternal behaviors and child social and communication skills for children who vary in biological risk. The intervention during infancy, Playing and Learning Strategies (PALS I), showed strong changes in maternal affective-emotional and cognitively responsive behaviors and infants' development. However, it was hypothesized that a 2nd intervention dose in the toddler-preschool period was needed for optimal results. Families from the PALS I phase were rerandomized into either the PALS II, the toddler-preschool phase, or a Developmental Assessment Sessions condition, resulting in 4 groups. Facilitation of maternal warmth occurred best with the PALS I intervention, while cognitive responsive behaviors were best supported with the PALS II intervention. Behaviors that required responsiveness to the child's changing signals (contingent responsiveness, redirecting) required the intervention across both the early and later periods.

A longitudinal study of word processing by first-grade children.

12 1st graders were tested 3 times during the school year on a word-reading task and on a task measuring the automaticity of their letter and word processing. Word-reading speed increased steadily during the year, and by the end of the year most of the Ss were able to extract meaning automatically from familiar printed words. The pattern of performance across tasks suggested that the ability to process letters automatically is acquired prior to the ability to read words rapidly and accurately.

General and context-specific encoding: A life-span development study.

Examined general and context-specific encoding across the life span, using the same procedure for all ages. Ss included 2nd- and 5th-grade schoolchildren, college students, and individuals aged 65+ yrs. Ss were asked to generate a personal word association to each of 24 target items prior to a surprise cued-recall test. The cues were either the S-generated associates or category labels. Ss at all ages recalled more associate-cued than category-cued items. Using the college students' performance as a baseline, 2nd graders performed equally poorly with both types of cues; 5th graders performed relatively more poorly with category than associate cues; and the older Ss performed relatively more poorly with associate than with category cues.

Reality Compared With Its Alternatives: Age Differences in Judgments of Regret and Relief.

Three experiments examined developmental change in children's understanding of regret and relief, two second-order emotions whose quality depends on a comparison between reality and "what might have been." In Experiment 1, participants 7 years of age and older, but not 5-year-olds, made regret-related emotion-response judgments that took into account a comparison of reality with its alternatives. In Experiment 2, 5-year-olds judged that an individual would feel better, rather than worse, when a counterfactual outcome was better than what actually occurred (the opposite of the pattern found with older children and adults). Experiment 3 focused on the understanding of relief. In contrast to the findings from Experiment I, the 7-year-olds in Experiment 3 made their judgments solely on the basis of what actually occurred.

Memorability judgments for high- and low-frequency words

Five experiments were conducted in order to examine subjects' judgments of the memorability of high- (HF) and low-frequency (LF) words in the context of a recognition memory task. In Experiment 1, the subjects were provided study/test experience with a list of HF and LF words prior to making memorability judgments for a new list of HF and LF items. The findings were consistent with previous evidence (Greene & Thapar, 1994; Wixted, 1992) suggesting that subjects are not explicitly aware of the greater recognition memorability of LF words. Experiments 2-5 embedded the memorability judgment task within the recognition test itself. In these experiments, the subjects consistently gave higher memorability ratings to LF items. The contrast between the pattern of results found when the subjects made their judgments at the time of list presentation (Experiment 1) and that when they made their judgments during the recognition test (Experiments 2-5) is consistent with recent evidence that even seemingly highly related metamnemonic judgments (e.g., ease of learning judgments vs. judgments of learning for the same items) may be based on very different factors if they occur at different points in the study/test cycle. The present findings are also consistent with the possibility that very rapid retrieval of memorability information for HF and LF words may affect recognition decisions and may contribute to the recognition memory word frequency effect.     

Processing relational and item-specific information: Effects of aging and division of attention.

64 young adults (aged 18–21 yrs) and 32 older Ss (aged 65–83 yrs) encoded items from categorizable lists under incidental learning conditions. Two orienting tasks were used: a category sorting task and a pleasantness rating task. The number of items/category was varied (between 2 and 14) within each list. In addition, 24 young adults performed the orienting tasks while simultaneously engaged in an attention-demanding secondary task (divided-attention condition). Recall declined with both age and division of attention, while recall clustering was greatest for the older Ss and least for the young divided-attention Ss. The effects of category size and orienting task on recall did not vary across groups. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
