Phonemic awareness and spelling: children's judgments do not always agree with adults

The ability to make explicit judgments about speech sounds is important in learning to read and write an alphabetic system. However, even when children can make consistent judgments about sounds their judgments do not always agree with those of adults. In this study, some children from groups of kindergartners (mean age 5 years, 10 months) and first graders (mean age 6, 7) stated that /tr/ (as in "truck") did not begin with the sound /t/. This judgment was reflected in these children's spellings: They tended to spell /t/ before /r/ with CH, reflecting its affrication. Parallel results were found for /dr/. Further, some children judged that /c/ (as in "chill") and /j/ (as in "Jill") began with /t/ and /d/, respectively. They used the letters T and D to spell these sounds. Thus, children's attention to a phonetic level may result in judgments of speech sounds and spellings that are different from those of adults.     

Career exploration in adulthood

The study described was designed to examine career exploration in the adult years, as seen from the perspective of decision-making behavior. Using conceptual models provided by H. B. Gelatt (Journal of Counseling Psychology, 1962, 9, 240–245) and D. V. Tiedeman (Personnel and Guidance Journal, 1961, 40, 15–21), two research questions were posed: (1) To what extent does exploration occur prior to more terminal career behaviors? and (2) To what extent are exploratory and terminal career decision modes interdependent? These questions were addressed by examining the series of decisions made by 95 subjects over a period of 18 years. The results supported the expectation that decisions made at earlier stages of development are more likely to be of an exploratory nature and that decisions made at later stages are more likely to be of a terminal nature. In addition, support was found for the hypothesis that decision-making strategies at various stages of development are interdependent.     

Parent vs. teacher reactions to problematic behavior of head start children

Studies of disciplinary responses to preschool children's transgressions often assume that subjects share the same degree of concern for the misbehavior under study. Individual differences in the strengths of different transgressions in eliciting disciplinary interventions were studied in 31 black mothers and 31 black teachers of Head Start children. Simulated situational urgency to discipline was measured by a Q-sort of 60 items depicting 10 types of misconduct observed in preschool classrooms. Attitudes of concern for the significances of the behaviors for the children's development were obtained through a separate rank-ordering procedure. Parents saw significantly more urgency in transgressions of social deportment. Teachers viewed aggressive and antisocial behaviors as more urgent, and tended to show closer agreement between intervention urgency and attitudes. Whereas teachers' interventions may be interpreted as responses to group child-care demands, the parents' concern for social deportment invites several interpretations.     

Predicting brain organization from dichotic listening performance: Cortical and subcortical functional asymmetries contribute to perceptual asymmetries

The patterns of perceptual asymmetry elicited by dichotic speech and complex pitch stimuli were evaluated in a group of 28 normal, right-handed subjects. As in previous studies, between 70 and 75% of the subjects showed a right-ear advantage for speech and left-ear advantage for pitch. However, less than half of the subjects (46%) showed the expected pattern on both tests. It is argued that the assumption of symmetrical, contralateral auditory pathway superiority during dichotic stimulation is only appropriate in roughly half of the dextral population. In the remaining half, significant subcortical asymmetries and/or a lack of contralateral advantage appear to be present. The assessment of complementary cortical functions should provide a way to reduce the confounding of cortical and subcortical contributions to auditory perceptual asymmetries, and thus provide a more accurate behavioral index of brain organization.     

Joint independent random utility models where one of the choice structures satisfies the strict utility model

It is known that one cannot construct an independent joint random utility model for which both the preference and aversion probabilities satisfy the strict utility model. Given this result, it is natural to ask what kind of relations are possible in such contexts. Here, for instance, we demonstrate that if a structure of preference and aversion probabilities are generated by a common independent random utility model, and if the preference probabilities satisfy the strict utility model, then the preference and aversion probabilities are related by what is known as the strong acceptance condition. We also prove an appropriate converse of this result. Finally, an example is given of a process (other than the random utility model) that is compatible with the assumption that a structure of preference and aversion probabilities satisfies a common strict utility model.     

The effect of voice and place among aphasic, nonaphasic right-damaged, and normal subjects on a metalinguistic task

Aphasic, nonaphasic right-damaged, and normal subjects sorted triads of stop consonants into pairs adjudged most similar. All groups sorted on the basis of linguistic features, but differed in their use of place versus voice: Normal and right-damaged subjects used place and voice equally often; aphasics relied significantly more upon voice than upon place. These results are interpreted to reflect an alteration at the level of linguistic representation in aphasics and not simply a perceptual difficulty. It is suggested that this altered representation stems from aphasics' extended use of normal linguistic capacities of the right hemisphere.     

Neologistic jargon aphasia: A case report

This study examined aspects of speech produced by an aphasic subject with neologistic jargon. Grammatical category, syllabic structure, and phonemic characteristics of neologisms, paraphasias, and correct productions were analyzed and compared. Results tended to confirm an anomic component in this type of aphasia and to support a role for the postactivation of phonemic units from prior utterances in the phonemic composition of some neologistic productions. In opposition to prior claims, however, the results also showed a striking similarity between neologisms and paraphasias, suggesting that similar mechanisms may be involved in both types of aphasic error.     

Preservation of orthographic knowledge in aphasia

A simple untimed lexical decision task was designed to test implicit letter recognition in aphasic patients. Half of the nonwords used in this task were orthographically regular pronounceable pseudowords, and half were orthographically irregular unpronounceable letter strings. Twenty-five randomly chosen aphasic patients with mild to severe degrees of aphasia participated in the study. Although only six of the patients performed the lexical decision task successfully, all 25 demonstrated the ability to distinguish orthographically regular from irregular letter strings and, by implication, the ability to recognize and make use of the identities of written letters.
