Development of phonetic memory in disabled and normal readers

The development of phonetic codes in memory of 141 pairs of normal and disabled readers from 7.8 to 16.8 years of age was tested with a task adapted from L. S. Mark, D. Shankweiler, I. Y. Liberman, and C. A. Fowler (Memory & Cognition, 1977, 5, 623–629) that measured false-positive errors in recognition memory for foil words which rhymed with words in the memory list versus foil words that did not rhyme. Our younger subjects replicated Mark et al., showing a larger difference between rhyming and nonrhyming false-positive errors for the normal readers. The older disabled readers' phonetic effect was comparable to that of the younger normal readers, suggesting a developmental lag in their use of phonetic coding in memory. Surprisingly, the normal readers' phonetic effect declined with age in the recognition task, but they maintained a significant advantage across age in the auditory WISC-R digit span recall test, and a test of phonological nonword decoding. The normals' decline with age in rhyming confusion may be due to an increase in the precision of their phonetic codes.     

Perceived qualifications,resource abundance,and resentment about deprivation

Two experiments tested the hypothesis that perceptions of being well qualified for a desired object will decrease individuals' resentment about deprivation when opportunities for obtaining the object are good (i.e., when the resource is abundant), but increase resentment when the resource is scarce. In the first experiment, unemployed nurses participated in a survey of the job situation for nurses. The initial questions in the survey were designed to manipulate respondents' perceptions of (a) their qualifications for employment, by affecting their perceived similarity to employed nurses (similar vs different), and (b) the job potential for unemployed nurses (improve vs worsen). In the second experiment, subjects competed over a number of trials with other participants for money that they had previously been promised. Some of the subjects had practiced the task ahead of time (qualified subjects), whereas others had not (unqualified subjects). In addition, the number of payments that were allegedly available was varied (many vs few). In both experiments, the manipulation of good qualifications reduced resentment when the resource was abundant, but did not significantly affect resentment when the resource was scarce. The implications of these results for understanding the determinants of resentment about deprivation are discussed.     

Beliefs in a Just World and Reactions to Personal Deprivation

ABSTRACT We hypothesized that strong believers in a just world would be motivated to perceive personal deprivation as fair and to report little resentment, compared to weak believers in a just world In two experiments, subjects performed a computer task to earn points toward a goal that had desirable consequences In the first study, some subjects chose their computer task, whereas other subjects were randomly assigned to a task In the second study, some subjects decided not to practice the task before the test trial, whereas other subjects learned after the test trial that the experimenter had forgotten to give them the opportunity to practice All subjects received bogus feedback indicating that they did not earn any points The predicted relation between beliefs in a just world and perceived fairness was obtained in both experiments, especially within the choice condition of Experiments and the experimenter error condition of Experiments The results show that beliefs in a just world have implications not only for perceptions of others, but also for self-perception     

Mobility Strategies and Career Outcomes: A Longitudinal Study of MBAs

This research examines the impact of work- and non-work-related mobility on salary, promotions, job satisfaction, and organizational commitment among 671 male and female managers over a 7-year period. Results indicated that those with frequent lateral moves had significant gain in salary increases compared to those who did not move. In addition, frequent lateral moves had a negative impact on work-related attitudes, specifically overall job satisfaction and organizational commitment. Implications of these findings for career strategies and future research are discussed.     

The role of reference in children's acquisition of a miniature artificial language

Nursery school children were presented with a simple miniature artificial language in one of three conditions. In the first, the stimuli to which the words referred contained an inherent lawful relationship and the language syntax reflected this relationship. In the second, the stimuli contained an inherent lawful relationship but the language syntax did not reflect this relationship. In the third, no lawful relationship existed among the stimuli to which the words referred so the language syntax imposed an arbitrary relationship among stimuli. Subjects in the first group were able to produce more correct utterances than those in the other two groups when the stimuli to which the words referred were not present, suggesting that some form of semantic mediation mechanism was being used. Evidence from novel constructions indicates that for both groups using stimuli containing an inherent lawful relation there were interactions between semantic learning mechanisms and syntax learning mechanisms.     

The effects of stimulus familiarization on patterns of visual selection

Patterns of visual selection were recorded as Ss viewed pairs of stimulus drawings in which the two members were either both incongruous or both banal. Prior to presenting the paired stimuli, S was preexposed to either one member of the stimulus pair or to the incongruous or banal counterpart of one member of the stimulus pair. The results indicate that: (1) preexposure to a stimulus reduced its potential to elicit looking responses, and the magnitude of that reduction was greater for incongruous stimuli than for banal stimuli; (2) preexposure to an incongruous stimulus affected the potential of its banal counterpart to elicit looking responses, but preexposure to a banal stimulus did not affect the potential of its incongruous counterpart to elicit similar responses; and (3) the reduced potential of the preexposed member of a stimulus pair to elicit looking responses waned after 10 sec. These results were discussed in light of an “information-conflict resolution” model of visual selection.     

Interference effects in tone memory

Memory for a standard tone in comparison to a subsequent test tone was examined in three experiments with three intervening tones between the standard and test tones. In each trial, the intervening tones were presented from one of seven frequency range and distance from the standard tone conditions. Experiment 1 tone patterns were played at four different presentation rates, and the subjects judged whether the test was higher or lower than the standard. Memory interference effects caused by the different intervening tone conditions could be accounted for by a directional shift in the standard tone memory toward the intervening tones and by a general decrease in the standard tone memory strength with more distant intervening tones. Interference effects were smaller for the rapid presentation rates because the intervening tones formed separate "perceptual streams." Two additional experiments presented the tone patterns in a task requiring the subjects to match a continuously variable tone to their memory of the standard (Experiment 2) and a task requiring them to judge whether the standard and test tones were the "same" or "different" (Experiment 3). These experiments showed large differences in interference effects as a function of the required judgment and the subjects' musical experience.
