The primary aim of the current study was to examine whether depleted cognitive resources might have ramifications for the formation of neutral and negative spontaneous false memories. To examine this, participants received neutral and negative Deese/Roediger-McDermott false memory wordlists. Also, for half of the participants, cognitive resources were depleted by use of an ego depletion manipul...

Plant species introduced into new regions can both leave behind co-evolved pathogens and acquire new ones. Traits important to infection and virulence are subject to rapid evolutionary change in both plant and pathogen. Using Stemphylium solani, a native foliar necrotroph on clovers (Trifolium and Medicago) in California, USA, we explore how plant-fungal interactions may change in an invasion c...

We investigated children's ability to generate associations and how automaticity of associative activation unfolds developmentally. Children generated associative responses using a single associate paradigm (Experiment 1) or a Deese/Roediger-McDermott (DRM)-like multiple associates paradigm (Experiment 2). The results indicated that children's ability to generate meaningful word associates, and...

Research on false memories has extensively used the recognition and recollection of lists of semantically associated words, called the Deese-Roediger-McDermott (DRM) paradigm. In the DRM procedure, the measure of accuracy/errors is usually the main dependent variable. In this paper we review research that integrated reaction time measures into the DRM paradigm and discuss the future contributio...

The Deese/Roediger-McDermott paradigm was used to investigate the effect of depression on true and false recognition. In this experiment true and false recognition was examined across positive, neutral, negative, and depression-relevant lists for individuals with and without a diagnosis of major depressive disorder. Results showed that participants with major depressive disorder falsely recogni...

Shifts in plant species phenology (the timing of life-history events such as flowering) have been observed worldwide in concert with rising global temperatures. While most species display earlier phenology with warming, there is large variation among, and even within, species in phenological sensitivity to rising temperatures. Other indirect effects of climate change, such as shifting species c...

Following the discovery of ergosterol by Tanret (l), Gerard (2) observed that not only ergot, but fungi in general, contain it. Gerard was the first to recognize ergosterol in yeast, although Nageli (3) had earlier obtained a yeast “cholesterol” in crude form. In traces ergosterol is now known to be widely distributed in both plant and animal kingdoms, but the fungi, and particularly the yeasts...

Bacteroid-containing cells of leguminous root nodules (Pisum and Trifolium) provide an environment in which the membrane envelope surrounding each bacteroid can exhibit unusual properties. The bacteroids are crowded, and frequently neighbouring membrane envelopes come into close contact. In such cases the two envelopes can fuse laterally to give a symmetrical tripartite membrane, probably consi...

We are engaged in a continuing study concerning the effect of time on plants. The approach is to apply a common statistic, within-group variation in morphological integration, to plants of different age or subjected to different treatments in a search for common underlying patterns. Within-group variation in morphological integration is an estimate of the relationship among variables. Previous ...

BACKGROUND AND AIMS Using two parental clones of outcrossing Trifolium ambiguum as a potential model system, we examined how during seed development the maternal parent, number of seeds per pod, seed position within the pod, and pod position within the inflorescence influenced individual seed fresh weight, dry weight, water content, germinability, desiccation tolerance, hardseededness, and subs...
