An analysis of speech perception in word deafness

A patient with a rather pure word deafness showed extreme suppression of right ear signals under dichotic conditions, suggesting that speech signals were being processed in the right hemisphere. Systematic errors in the identification and discrimination of natural and synthetic stop consonants further indicated that speech sounds were not being processed in the normal manner. Auditory comprehension improved considerably however, when the range of speech stimuli was limited by contextual constraints. Possible implications for the mechanism of word deafness are discussed.     

Fear of failure in males: A more salient factor than fear of success in females?

Sex differences in self-attributions following winning or losing in a highly competitive achievement-type situation were investigated. Subjects competed in same- or mixed-sex pairs on an anagram task which was prearranged in difficulty so that one subject would clearly defeat his/her partner. A significant sex of subject × outcome interaction emerged. Males were more likely to attribute their successes to skill and failures to luck. Females attributed both their successes and failures to a relatively equal amount of skill. This self-defensive bias in males was interpreted as indicating a greater fear of failure in males. The relatively rational and objective attributions of females did not support a female fear of success hypothesis. No significant interactions with sex of partner on this variable were found. Finally, subjects were asked to rate their opponents on a series of personality, attractiveness, and happiness dimensions. Neither males nor females were differentially evaluated as a function of winning or losing.The research reported here was partially supported by a grant to the first author from the California State University, Fresno Foundation.     

Choice Shifts In Political Decisionmaking: Federal Judges and Civil Liberties Cases

The purpose of this article is to investigate whether group-induced attitudinal shifts in decisionmaking take place outside the experimental laboratory and whether choice shift theory can be applied to the understanding of political behavior of actors engaged in socially relevant decisionmaking. A random sample of civil liberties decisions in Federal District Courts for the years 1963–1968 were examined. The hypothesis that there are systematic differences between single-judge and collegial court decisions was confirmed. Parties claiming a violation of constitutional rights increase the probability of successfully convincing a district judge when they are able to have their litigation heard by a three-judge court. The finding that judges are more likely to shift to a libertarian position when moving from the individual to the collegial decisionmaking condition holds when the data are examined in aggregate form as well as when the behavior of individual judges is studied under both decisionmaking settings.     

Reading without phonology: Evidence from aphasia

This study of an aphasic dyslexic supports the view that there are separate visual and phonological pathways in reading. The patient retained a reading vocabulary of at least 16 500 words although she was unable to perform operations that critically depend on grapheme-to-phoneme conversion; these included reading nonsense words, recognizing rhymes and homophones, and accessing lexical entries from homophonic spellings such as “kote”. Typographical variation, such as mixed case presentation, did not interfere with her reading performance, which suggests that it is mediated by letter identification rather than by a wholistic method of word recognition. The total performance pattern strongly suggests that this patient identifies words by matching particular letter-strings with their corresponding meanings.     

Derogation of an innocent victim as a function of authoritarianism and involvement

Two studies are reported in which observers witnessed a peer (learner) receiving electric shock and where they did or did not play a role in her suffering (Involved vs Noninvolved conditions). It was found in both studies that while High authoritarians were more likely than Low authoritarians to derogate the learner in Involved conditions, the reverse was true in Noninvolved conditions. These significant interactions (p < .03, p < .01) were interpreted in terms of Low authoritarians derogating in order to preserve their belief in a “just world” and High authoritarians derogating in order to avoid self-blame.     

The word order problem in agrammatism : I. Comprehension

The results of a picture-pointing comprehension test show that agrammatic aphasics have difficulty understanding sentences in which the underlying semantic roles are marked by the order of noun phrases around a verbal element. Agrammatic patients performed poorly on reversible constructions involving spatial prepositions (e.g., “The square is above the circle”) and verbs (e.g., “The dancer applauds the clown”). These results have significance for the interpretation of the underlying disturbance in agrammatism—whether the deficit is syntactic or purely phonological.     

Applying principles of development to help at-risk preschoolers develop numeracy

In a yoked control design, multicultural Head Start 4-year-olds played numerous games involving either numeracy or the oddity principle and insertions into series. Children showed better mastery of oddity and insertions after playing games directed at those two concepts. Numeracy scores on the McCarthy Scales of Children's Abilities (D. McCarthy, 1972) were equivalent for children who played numeracy games and children who played oddity and insertion games. These results are consistent with other research indicating that the understanding of oddity relations and that of insertions are key transitional thinking abilities that support numeracy at the preschool-kindergarten interface.     

Contrasting effects of phonological priming in aphasic word production

Two fluent aphasics, IG and GL, performed a phonological priming task in which they repeated an auditory prime then named a target picture. The two patients both had selective deficits in word production: they were at or near ceiling on lexical comprehension tasks, but were significantly impaired in picture naming. IG's naming errors included both semantic and phonemic paraphasias, as well as failures to respond, whereas GL's errors were mainly phonemic and formal paraphasias. The two patients responded very differently to phonological priming: IG's naming was facilitated (both accuracy and speed) only by begin-related primes (e.g. ferry-feather), whereas GL benefited significantly only from end-related primes (e.g. brother-feather), showing no more than a facilitatory trend with begin-related primes. We interpret these results within a two-stage model of word production, in which begin-related and end-related primes are said to operate at different stages. We then discuss implications for models of normal and aphasic word production in general and particularly with respect to sequential aspects of the phonological encoding process.
