This study investigates the influence on sentence encoding of activating appropriate contextual knowledge. A group of 72 undergraduate students randomly assigned to four treatment groups read and were later asked to recognize sentences from a passage. In one group, subjects were told nothing about the passage from which the sentence was taken. In…

This report is the first in a two-part series introducing an interactive activation model of context effects in perception. A model for the perception of letters in words and other contexts is described and applied to a number of experiments. It is proposed that the model accounts for (1) the perceptual advantage for letters in words compared to…

This report is the second in a two-part series introducing an interactive activation model of context effects in perception. In the first part, a model for the perception of letters in words and other contexts was described and applied to a number of experiments. This second part applies the same model to a number of new experiments designed to…

The experiments reported here are aimed at exploring in more detail the possibility that context can improve perception itself. In particular, they are concerned with clarifying the conditions under which context might aid perception and with localizing the stage of processing at which context would have its effects.

Experiments tested the predictions that words are perceived more accurately in strongly constraining word contexts than in weakly constraining word contexts, and that a strong perceptual advantage would be present for letters in words vs. letters alone or in unrelated-letter strings. Several alternative theories of word perception are discussed.…

Earlier research with the lexical decision task led to the hypothesis that semantic context facilitates the encoding of words related to the context. Six experiments which employed different tasks (e.g., making a lexical decision) and different experimental paradigms (e.g., tachistoscopic exposures with masking stimuli) further investigated this…

Factors were investigated under acquisition and retention conditions which might be expected to counteract interference brought on by mixing sight and phonics methods. Experiment 1 dealt with training kindergarten children to attend to and encode letter pattern cues and the word's contextual cues. Subjects were trained individually in a series of…

Five orders of approximation to normal English prose were constructed; 5th, 10th, 25th, 50th, and 100th plus. Five cloze tests were then constructed by inserting blanks for deleted words in 5 word segments (5th order), 10 word segments (10th), 25 word segments (25th), 50 word segments (50th), and 100 word segments of five different passages of…

In order to teach in the content area, a teacher must accept five basic premises: (1) Reading in the content field is part of the total school program. (2) All teachers are responsible for helping students read the text in a specific subject. (3) The focus of teaching is changed from merely teaching content to how to read and understand the…

In this study, eight groups of kindergarten children were trained to discriminate position and order differences in verbal and nonverbal item sequences in the context of a matching task or an associative learning task or both. Transfer was measured by having the subjects sight learn a list of words contrasting in position and order. Subsequently,…

Cloze procedure, a testing method which systematically deletes words in written prose and then measures the accuracy of the information is reviewed from a historical viewpoint. Redundancy is placed in a verbal context and can be noted on three separate levels of language: (1) surface syntactic structure; (2) deep syntactic structure; and (3)…

Perceptual units are involved in the reading process in a particular way. Reading starts with patterns of visual perception visual stimuli in combination with either previously learned information or a strategy for selectively attending to part of the stimuli. Whether the visual pattern selected for deeper information processing is a letter, a…
