Memory for the time associated with past events is critical for our understanding of episodic memory and its development. Relatively little is known about the factors that influence temporal memory development. One such factor examined in the literature is semantic knowledge for time (conventional time knowledge; CTK). Other possible factors…

It is well documented that exercise plays a critical role in maintaining physical health. More recently, a growing body of research has begun to focus on the mental benefits of exercise ranging from reducing depression to enhancing various cognitive abilities like memory and attention. These abilities are paramount for learning to occur, and thus,…

Recent studies indicate children who are deaf and hard of hearing who use cochlear implants or hearing aids know fewer spoken words than their peers with typical hearing, and often those vocabularies differ in composition. To date, however, the interaction of a child's auditory profile with the lexical characteristics of words he or she knows has…

In clinical and forensic evaluations, clinical neuropsychologists measure performance validity using standalone and embedded measures. Given the need to capture neuropsychological functioning through a variety of cognitive tests, newer, more sensitive measures should be evaluated for their utility in comparison to already established measures.…

This article evaluates the predictions of an algorithmic-level distributed associative memory model as it introduces, propagates, and resolves ambiguity, and compares it to the predictions of computational-level parallel parsing models in which ambiguous analyses are accounted separately in discrete distributions. By superposing activation…

Prior research suggests that the effectiveness of retrieval practice may be moderated by response format: overt retrieval (e.g., typing a response) outperforms covert retrieval (e.g., mentally recalling a response) for complex materials like definitions, but both forms of retrieval are equally effective for simple materials like single words.…

We analyzed a Japanese lexical database to investigate the structure of the lexical environment based on the hypothesis that the lexical environment is optimized for the functioning of verbal working memory. Our prediction was that, as a consequence of the cultural transmission of language, low-imageable meanings tend to be represented by frequent…

This study aims to examine the relationship between vocabulary proficiency and short-term memory capacity in deaf or hard-of-hearing (DHH) children. We test the hypothesis that the relationship between vocabulary skills and digit span performance could be strengthened when the digit span task encompasses cross-modal integration processes. A group…

The goal of the present study was to test theories about the extent to which individual differences in word reading align with those in spelling and the extent to which other cognitive and linguistic skills play different roles in word reading and spelling. Using data from 1,116 children ranging from 8 to 17 years, we modeled word reading and…

In this study, we examined to what extent orthographic skills, phonological processing, oral vocabulary, and word memory accounted for variance in reading comprehension among upper-elementary school children with and without dyslexia. The tasks came from the Tests of Dyslexia (TOD). Data from 753 participants (typically developing n = 575;…

Incentives can decrease performance by undermining intrinsic motivation. How such an interplay of external reinforcers and internal self-regulation influences memory processes, however, is less known. Here, we investigated their interaction on memory performance while learning the meaning of new-words from their context. Specifically, participants…

This study first validates a survey on self-regulated vocabulary learning strategies. It then examines the effects on the acquisition of new second language (L2) words from a reading text of three word-focused exercise conditions: reading + marginal glosses, reading + gap-fill and reading + sentence writing. It also evaluates the extent to which…

Purpose: This study aimed to investigate how hearing loss affects (a) spoken language processing and (b) processing of faster speech in school-age children who are deaf and hard of hearing (DHH). Method: Spoken language processing was compared in thirty-six 7- to 12-year-olds who are DHH and 31 peers with normal hearing using a word detection…

A growing number of studies have focused on uncovering linguistic and cognitive skills predictive of reading comprehension. Vocabulary knowledge (VK) and morphological awareness (MA) are two important linguistic variables for reading comprehension. In contrast, working memory (WM) is an essential cognitive variable for reading comprehension. The…

Across three separate investigations, this dissertation documents work examining the role of higher-order processes and cognitive effort during the top-down compensatory repair of degraded speech, specifically perceptual restoration. Perceptual restoration is a phenomenon where a listener can perceptually restore or repair speech…
