Age of acquisition, ageing, and verb production: Normative and experimental data

Young and old adults were shown pictured or written verbs and asked to name them as quickly as possible. Simultaneous multiple regression was used to investigate which of a set of potential variables predicted naming speed. Age of acquisition was found to be an important predictor of naming speed in both young and old adults, and for both word and picture naming. Word frequency predicted picture-naming speed only in older adults and failed to make any significant contribution to word-naming speeds for either group of participants. The respective loci and roles of age of acquisition and frequency in lexical processing are discussed in the light of these findings.     

The Moderating Effect of the Negative Impact of Recent Life Events on the Relation between Intrinsic Religiosity and Death Ideation in Older Adults

Researchers tested the hypothesis that the negative impact of recent life events would moderate the relationship between intrinsic religiosity and death ideation in older adults. Participants (n = 272) completed assessments of death ideation, intrinsic religiosity, and negative impact of recent life events. We confirmed the presence of concurrent moderation and found that older adults with greater negative impact of recent life events and high intrinsic religiosity reported greater death ideation. These relatively surprising findings may be due to reduced fear of death in intrinsically religious older adults, an explanation consistent with previous research.     

Imagery Interference Diminishes in Older Adults: Age-Related Differences in the Magnitude of the Perky Effect

Studies have documented the negative effects of mental imagery on perception (also known as the Perky effect) in younger adults, but imagery-interference effects in older adults have never been assessed. Two experiments examined this issue directly. Experiment 1 demonstrated that visual mental images diminish visual acuity in younger adults (mean age = 19.0) but not older adults (mean age = 73.6). Experiment 2 obtained parallel results, showing that visual imagery interfered with performance on a visual detection task in younger (mean age = 18.7) but not older adults (mean age = 66.7). Processes underlying age-related differences in imagery-interference effects are discussed and implications of these results for changes in cognitive performance in older adults are considered.     

Student Agency in Literacy: Validation of the Student Agency Profile (StAP)

Abstract

There have been recent calls to support student agency in the field of literacy. Agency, which we define in the context of schooling, is a multidimensional construct where individuals exert influence and create opportunities in the learning context through intentions, decisions, and actions. We propose highlighting agency as an interconnected construct, which includes self-perception as readers and writers, intentionality, choice-making, persistence, and interactiveness. Elementary students (n?=?1,726) completed surveys of their agency along with standardized literacy assessments. Statistical analyses largely aligned with the hypothesized dimensions of agency. Relationships to student literacy achievement were stronger in grades 3^rd–5^th than in 1^st–2^nd grades. Discussion highlights how elementary students have a voice in their agency as it pertains to literacy. Implications for future research and practice are discussed.     

Interactive Effects of Chronic Health Conditions And Financial Hardship On Episodic Memory Among Older Blacks: Findings From The Health And Retirement Study

Previous research links chronic health conditions and financial hardship to cognitive outcomes among older Blacks. However, few studies have explored the moderating effect of financial hardship on chronic disease burden and specific cognitive domains. This study examined whether financial hardship (as measured by difficulty paying monthly bills) modifies the impact of self-reported chronic health conditions (e.g., diabetes, stroke) on episodic memory among 871 older Blacks (50+ years) in the 2006 Health and Retirement Study . Financial hardship modified the association between chronic disease burden and episodic memory performance such that individuals who reported very little difficulty paying their monthly bills had significantly lower memory scores at high levels of disease burden compared to those reporting high financial difficulty after controlling for age, gender and education (F 2, 49 = 5.03, p = .010). This cross-sectional study suggests that both financial and physical wellbeing may have joint effects on cognitive health in older Blacks.     

Basic Language Skills and Young Children's Understanding of Causal Connections During Storytelling

The current study examined the role of basic language skills for individual differences in preschoolers’ understanding of causal connections. Assessments of basic language skills, expressive vocabulary, phonological processing, and receptive language comprehension were examined in relation to the production of causal connections in a storytelling task, at two time periods. Similar to previous cross-sectional research, children's causal connections increased over six months. As hypothesized, expressive vocabulary and phonological processing predicted causal connections at Time 1. Six months later, only phonological processing predicted causal connections. Results provide new information regarding the significance of basic language skills for early narrative skills.
