This study investigated the relationship between semantic and episodic memory as they support lexical access by healthy younger and older adults and individuals with Alzheimer's disease (AD). In particular, we were interested in examining the pattern of semantic and episodic memory declines in AD (i.e., word-finding difficulty and impaired recent…

What aspects of spatial relations influence speakers' choice of locative? This article presents a study of static spatial descriptions from 24 languages. The study reveals two kinds of spatial terms evident cross-linguistically: specific spatial terms and general spatial terms (GSTs). Whereas specific spatial terms--including English…

Native-born Estonian men (N = 1495), 18-23 years old, participated in a study on relationships between the level of education and noncognitive characteristics of mind (so-called Characteristic Adaptations: attitudes, values, self-concept, etc.). In addition to Characteristic Adaptations, the model included parents' level of education, personality…

Many models of word recognition predict that neighbours of target words will be activated during word processing. Cascaded models can make the additional prediction that semantic features of those neighbours get activated before the target has been uniquely identified. In two semantic decision tasks neighbours that were congruent (i.e., from the…

We present a microgenetic analysis of the gestures that children produce as they talk about a balance task. Children gesture spontaneously on this task and here their hand gestures are considered in relation to the accompanying speech. By close examination of 21 children's single sessions, and the 163 iconic gestures they produced (a mean of 7.6…

The authors present a Bayesian framework for understanding how adults and children learn the meanings of words. The theory explains how learners can generalize meaningfully from just one or a few positive examples of a novel word's referents, by making rational inductive inferences that integrate prior knowledge about plausible word meanings with…

Purpose: This study presents evidence that gesture is a means to understanding the semantic representations of toddlers. Method: The data were part of a study of toddlers' word learning conducted by N. C. Capone and K. K. McGregor (2005). The object function probe from that study was administered after 1 exposure and after 3 exposures to objects.…

Judgments of associative memory (JAM) were indexed by ratings given to pairs of cue and response words. The normed probabilities, p(response|cue), were obtained from free association norms. The ratings were linearly related to the probabilities. The JAM functions were characterized by high intercepts (approximately 50 on a 100 point scale) and…

The contribution of the left inferior prefrontal cortex in semantic processing has been widely investigated in the last decade. Converging evidence from functional imaging studies shows that this region is involved in the "executive" or "controlled" aspects of semantic processing. In this study, we report a single case study of a patient, PW, with…

In this study, we use an auditory picture-word interference task to examine an anomic individual, NP. NP produced semantic errors in picture naming, but his comprehension was relatively well preserved. In the task, pictures to be named were accompanied by semantically, phonologically or unrelated distractors, presented at onsets ranging from…

Most naming treatments in aphasia either assume a phonological or semantic emphasis or a combination thereof. However, it is unclear whether semantic or phonological treatments recruit the same or different cortical areas in chronic aphasia. Employing three persons with aphasia, two of whom were non-fluent, the present study compared changes in…

Cognitive control mechanisms permit memory to be accessed strategically, and so aid in bringing knowledge to mind that is relevant to current goals and actions. In this review, we consider the contribution of left ventrolateral prefrontal cortex (VLPFC) to the cognitive control of memory. Reviewed evidence supports a two-process model of mnemonic…

We report a Chinese-speaking patient WJX with left temporal lobe ischemic damage resulting in dementia. Similar to English speaking patients with this pathology, WJX showed impaired semantic system functioning together with a well preserved ability to read aloud Chinese characters including characters with unpredictable mappings between…

The present research explores whether obtaining semantic negative priming from a single ignored word depends on whether that word is either consciously or unconsciously perceived. On each trial a prime word was briefly displayed and followed either immediately or after a delay by a pattern mask. The mask offset was followed by a probe display…

Assessing whether domain-general mechanisms could account for language acquisition requires determining whether statistical regularities among surface cues in child directed speech (CDS) are sufficient for inducing deep syntactic and semantic structure. This paper reports a case study on the relation between pronoun usage in CDS, on the one hand,…
