In two picture-word interference experiments we examined whether phrase boundaries affected how far in advance speakers plan the sounds of words during sentence production. Participants produced sentences of varying lengths (short determiner + noun + verb or long determiner + adjective + noun + verb) while ignoring phonologically related and…

The location of an object is often described by spatially relating it to a known landmark. The spatial terms used in such descriptions can provide various types of information. For example, projective terms such as "above" indicate direction but not distance, whereas proximal terms such as "near" indicate distance but not direction. Previous…

This study investigates the role of specific inhibitory processes in lexical ambiguity resolution. An attentional view of inhibition and a view based on specific automatic inhibition between nodes predict different results when a neutral item is processed between an ambiguous word and a related target. Subjects were 32 English speakers with normal…

The way cognitive, event-related brain potentials (ERPs) can aid in further understanding of memory span change in children is discussed. ERPs are time-dependent changes in electrical activity of the brain (as recorded by scalp electrodes) following the presentation of a physical stimulus through auditory, visual, or somatosensory modalities. The…

Relationships between verbal ability, semantic category clustering, and speed of retrieval were studied. Lists of 30 words were presented individually to subjects with high- and low-verbal ability under free recall, delayed free recall, and clustering recall conditions. In the first stage of recall, high verbals displayed a significantly higher…

This report summarizes the research results and provides a reference. The basic question addressed was, "Is performance on multi-component tasks predicted by performance on the individual components performed separately?" In the first series of experiments, a dual task involving memory and verbal processing components to predict a…

This study examined the relationship of tutorial enrichment of cognitive processes and reinforcement of lengthened response latency to measurements of impulsivity in 3- and 4-year-old children in a typical preschool setting. In a pretest-posttest control group design, 48 impulsive subjects (24 male and 24 female) were randomly assigned to tutorial…

This paper discusses three studies which examined the interaction of dimensional dominance with the attentional components of alertness and encoding. In Study I, twenty 6- and 7-year-olds observed thirty 3-second exposures of a color, then participated in a 40-trial choice reaction time task in which the familiarized color and a novel color served…

Four possible mechanisms for short-term item recognition are distinguished. Manipulations of recency, particularly of negative probe items, provide critical tests. Two experiments were conducted using Sternberg's varied-set reaction time paradigm, coupled with procedures intended to minimize rehearsal and control the recency of probes and memory…

Reaction time to verify property statements was examined in the context of two semantic distance factors--typicality of the category member in the subject of the statement, and dominance of the category member's property in the predicate. (Author/NCR)

Meyer, Schvaneveldt, and Ruddy report that semantic context has a larger effect on visually degraded words than on undegraded words. Degrading stimuli takes place by superimposing a dot pattern over letters thereby slowing information processing. Four experiments explore alternative explanations of this research finding.

The study examines the role of conceptual tempo in creativity and problem solving. It was hypothesized that reflective children would do well on tasks involving evaluation components, while impulsive children would do well on typical creativity tasks. Results indicated no significant differences among the conceptual tempo groups. (Author)

Eighty-one university students were given a battery of reaction time tests and a group test of intelligence which yielded timed and untimed scores. Multiple regression analyses indicated that speed of information-processing was an equally good predictor of timed and untimed intelligence test performance. (Author/LMO)

It is evident from this task that preschool children can remember simple pictures as well as their names, that either pictorial or verbal codes can mediate memory of either pictures or words in accordance with task demands, and that same-different judgments tend to be faster to pictures than to words.

Methods used in the present study confirm that rejection latencies are a reliable index of certain strategies adopted in processing prose. (Author)
