Accuracy Tradeoff

In this chapter, we review key insights gained by using the speed-accuracy tradeoff (SAT) technique to address psycholinguistic and linguistic issues. SAT evidence has been instrumental in integrating sophisticated memory models into psycholinguistic theory, and bears on several linguistic issues in experimental syntax. We explain how SAT can provide clear evidence about time course of processing that is unconfounded by accuracy or probability of interpretation over trials, and in so doing, can fruitfully inform debates about processing and representation.

Nonsense Syllables

Recent research into global memory models has focused on gaining empirical support for the predictions these models make. Clark and his colleagues produced no conditions in which a test item and a distractor shared a common component within a number of experiments using an associative recognition task and have reasoned that recall might play a role in the task. This experiment used nonsense syllables to reduce further the role of recall in the associative recognition task and produce the predicted advantage from overlap. The manipulations produced equal performance between test conditions (overlapping vs nonoverlapping) and superior performance on a long list versus a short list, i.e., a negative list-length effect. The implications of these findings for various global memory models are discussed.

Inhibition Process

Memory suppression is investigated with the no-think paradigm, which produces forgetting following repeated practice of not thinking about a memory [Anderson MC, Green C (2001) Nature 410:366–369]. Because the forgotten item is not retrieved even when tested with an independent, semantically related cue, it has been assumed that this forgetting is due to an inhibition process. However, this conclusion is based on a single stage to recall, whereas global memory models, which produce forgetting through a process of interference, include both a sampling and a recovery stage to recall. By assuming that interference exists during recovery, these models can explain cue-independent forgetting. We tested several predictions of this interference explanation of cue-independent forgetting by modifying the think/no-think paradigm. We added a condition where participants quickly pressed enter rather than not thinking. We also manipulated initial memory strength and tested recognition memory. Most importantly, learning to quickly press enter produced as much cue-independent forgetting as no-think instructions. Demonstrating the adequacy of two-stage recall, a simple computational model (SAM-RI) simultaneously captured the original cue, independent cue, and recognition results.

The physiological, biochemical, and ultrastructural aspects of the symbiotic relationship between the Chlorella-like algae and the hydra have been intensively investigated. Reciprocal cross-transfer of the Chlorellalike algae between different strains of green hydra provide a system for the study of cell recognition. However, our attempts to culture the algae free of the host hydra of the Florida strain, Hydra viridis, have been consistently unsuccessful. We were, therefore, prompted to examine the isolated algae at the ultrastructural level on a time course.

We have studied the destruction of rabbit muscle actin filaments by osmium tetroxide (OSO4) to develop methods which will preserve the structure of actin filaments during preparation for transmission electron microscopy.Negatively stained F-actin, which appears as smooth, gently curved filaments in control samples (Fig. 1a), acquire an angular, distorted profile and break into progressively shorter pieces after exposure to OSO4 (Fig. 1b,c). We followed the time course of the reaction with viscometry since it is a simple, quantitative method to assess filament integrity. The difference in rates of decay in viscosity of polymerized actin solutions after the addition of four concentrations of OSO4 is illustrated in Fig. 2. Viscometry indicated that the rate of actin filament destruction is also dependent upon temperature, buffer type, buffer concentration, and pH, and requires the continued presence of OSO4. The conditions most favorable to filament preservation are fixation in a low concentration of OSO4 for a short time at 0°C in 100mM sodium phosphate buffer, pH 6.0.
