Mechanisms of aural encoding: VI. Consonants and vowels are remembered as subsets of distinctive features

An attempt was made to examine the manner in which consonants and vowels are coded in short-term memory. under identical recall conditions. Ss were presented with sequences of consonant-vowel digrams for serial recall. Sequences were composed of randomly presented consonants paired with/a/ or randomly presented vowels paired with /d/. Halle’s distinctive feature system was used to generate predictions concerning the frequency of intrusion errors. among phonemes. These predictions were based on the assumption that phonemes are discriminated in memory in terms of their component distinctive features, so that intrusions should most frequently occur between phonemes sharing similar distinctive features. The analysis of intrusion errors revealed that each consonant and vowel phoneme was coded m short-term memory by a particular combination of distinctive features which differed from one phoneme to another. A given phoneme was coded by the same set of distinctive features regardless of the number of syllables in the sequence. However, distinctive feature theories were not able to predict the frequency of intrusion errors for phonemes presented in the middle serial positions of a sequence with 100% accuracy. The results of the experiment support the notion that consonant and vowel phonemes are coded in a similar manner in STM and that this coding involves the retention of a specific set of distinctive features for each phoneme.     

The Marriage Contract

This article is intended to serve as an introduction to the concept of the marriage contract, which has proved to be a useful clinical tool for clarification and treatment of troubled marriages. Transactional as well as intrapsychic factors are important aspects of marital dynamics. The contract concept employs both these behavioral parameters and facilitates therapeutic intervention at both levels.     

A comparative evaluation of several prominent methods of oblique factor transformation

The oblimax, promax, maxplane, and Harris-Kaiser techniques are compared. For five data sets, of varying reliability and factorial complexity, each having a graphic oblique solution (used as criterion), solutions obtained using the four methods are evaluated on (1) hyperplane-counts, (2) agreement of obtained with graphic within-method primary factor correlations and angular separations, (3) angular separations between obtained and corresponding graphic primary axes. The methods are discussed and ranked (descending order): Harris-Kaiser, promax, oblimax, maxplane. The Harris-Kaiser procedure—independent cluster version for factorially simple data,P'P proportional to , with equamax rotations, for complex—is recommended.This paper is based upon part of the author's doctoral dissertation [Hakstian, 1969] completed at the University of Colorado. The author is greatly indebted to Dr. Gene V Glass, who, as thesis advisor, generously contributed his time, erudition, and encouragement.     

Post-retinal storage? Some further observations on Parks’ camel as seen through the eye of a needle

Parks recently reported observations with an apparatus in which successive slices of a stimulus figure could be entered on the same retinal locus. He reported that when this was done, a visual percept of the figure appeared, but one that appeared condensed in length. From this he argued that the slices, differing only in time of arrival, must be stored post-retinally and then reconstructed spatially to form the coherent figure again. In attempting to replicate this important conclusion, we found, contrary to Parks, that the appearance of the percept occurred only when the slices were spread out over the retina, and not when they were entered on the same spot. Thus, the percept is probably due to much more understandable poor temporal resolution, rather than spatial integration. Shape distortions were found corresponding to Parks’ reports, but only in the absence of any visual percepts. In spite of the failure to support all of Parks’ conclusions, the effects are seen as very intriguing ones, and may have critical theoretical ramifications.     

Scoring weighted multiple keyed tests on the IBM counting sorter

Tests or personal inventories with differential item response weights may be scored by means of punch card equipment. Detailed instructions are given for preparing the cards and scoring the forms. The scoring speed is approximately four to eight times that attained by manual scoring.The author is indebted to H. M. Cox, University of Nebraska, for certain suggestions on the columnar coding and the method of checking herein presented.     

Disentangling boundary extension and normalization of view memory for scenes

Boundary extension (BE) is a memory error for close-up views of scenes in which participants tend to remember a picture of a scene as depicting a more wide-angle view than what was actually displayed. However, some experiments have yielded data that indicate a normalized memory of the views depicted in a set of scenes, suggesting that memory for the previously studied scenes has become drawn toward the average view in the image set. In previous studies, normalization is only found when the retention interval is very long or when the stimuli no longer appear to represent a spatial expanse. In Experiment 1, we examine whether normalization can influence results for scenes depicting a partial view of space and when the memory test occurs immediately following the study block by manipulating the degree of difference between studied close-up and wide-angle scenes. In Experiment 2, normalization is induced in a set of scenes by creating conditions expected to lead to memory interference, suggesting that this may be the cause of view normalization. Based on the multi-source model of BE, these scenes should be extended during perception (Intraub, H. (2010). Rethinking scene perception: A multisource model. Psychology of Learning and Motivation, 52, 231–265). In Experiment 3, we show that BE is indeed observable if the same scenes are tested differently, supporting the notion that BE is primarily a perceptual phenomenon while normalization is a memory effect.     

The ‘conjunction fallacy’ revisited: how intelligent inferences look like reasoning errors

Findings in recent research on the ‘conjunction fallacy’ have been taken as evidence that our minds are not designed to work by the rules of probability. This conclusion springs from the idea that norms should be content‐blind—in the present case, the assumption that sound reasoning requires following the conjunction rule of probability theory. But content‐blind norms overlook some of the intelligent ways in which humans deal with uncertainty, for instance, when drawing semantic and pragmatic inferences. In a series of studies, we first show that people infer nonmathematical meanings of the polysemous term ‘probability’ in the classic Linda conjunction problem. We then demonstrate that one can design contexts in which people infer mathematical meanings of the term and are therefore more likely to conform to the conjunction rule. Finally, we report evidence that the term ‘frequency’ narrows the spectrum of possible interpretations of ‘probability’ down to its mathematical meanings, and that this fact—rather than the presence or absence of ‘extensional cues’—accounts for the low proportion of violations of the conjunction rule when people are asked for frequency judgments. We conclude that a failure to recognize the human capacity for semantic and pragmatic inference can lead rational responses to be misclassified as fallacies.

Coerced or nonvoluntary confessions

Police may engage in deceptive and coercive interrogations to obtain confessions. When a confession is later retracted, judges and juries must assess the totality of the circumstances surrounding the confession, including the interrogation techniques used and the effects of these tactics on the particular defendant. A suspect who is vulnerable and confused or who is given false evidence by a coercive interrogator may produce a false confession. Expert testimony may be necessary to help jurors understand the circumstances that lead to nonvoluntary confessions. © 1998 John Wiley & Sons, Ltd.
