Transformations. I. The effect of DAF on sentence generation

A hypothesis based on the psycholinguistic derivation of sentences was tested. The task required that sentences temporarily stored in memory be transformed and spoken with delayed auditory feedback. An instruction to repeat the stimulus sentence verbatim or grammatically transform it was placed either immediately before or immediately after the sentence. Two measures of interference were obtained based on the syllable rates for the response times. The different grammatical forms showed significant variation in the amount of interference, but the amount of interference appeared to relate primarily to the length of the transformed sentence rather than to its derivational complexity. Interaction between the position of the instruction and the sentence generation task is discussed in terms of the underlying memory functions involved. A further test was proposed.     

Ineffective deception in conformity research: Some causes and consequences

Suspiciousness of deception threatens the internal validity of the conformity experiment, and analyses suggest it is becoming more widespread. After being led to believe their own ability in a visual judgment task was higher, lower, or the same as the ability of the other group members, 65 undergraduate women made visual and informational judgments in the Crutchfield apparatus. Major findings include treatment effects on suspiciousness, less conformity by suspicious Ss, and ‘significant’ treatment effects on conformity only when suspicious Ss were removed from the analyses. Measures of self-confidence and confidence in others were significantly related to and likely determinants of suspiciousness. Implications for improving deception in conformity research are discussed.     

The role of letter recognition in word recognition

In a paradigm that avoids methodological problems of earlier studies, evidence was gathered addressed to the question of whether we read letter by letter. If word recognition involves letter recognition, then the difficulty of recognizing a word should vary with the difficulty of recognizing its letters. This was tested by assessing letter difficulty in two letter discrimination tasks and in a letter naming task, and then comparing 15 adult subjects' visual recognition latency to 72 easy-letter words and to 72 difficult-letter words. Word frequency and word length were also manipulated. Results indicated no effect for letter difficulty, although recognition latency reliably decreased with word frequency and monotonically increased with word length (21 msec/letter), suggesting that we do not read letter by letter, but that whatever plays a role in word recognition is smaller than the word and correlated with word length in letters.     

Recognition memory for words and pictures at short and long retention intervals

In two experiments, subjects studied a long series of words and pictures for recognition. Retention intervals varied from several minutes to a few months. The complicated testing procedures in Experiment I required the use of a traditional correction for guessing to obtain estimates of subjects' memory performance. A comparable, but simpler, design in Experiment II permitted the calculation of sensitivity and bias measures. In both studies, pictorial memory was superior to verbal memory at all retention intervals tested, and this advantage was essentially constant over time. In addition, the experiments identified an increasing tendency to call verbal test items "old" over time. Bias scores in Experiment H revealed that subjects adopted a more lenient criterion in responding to words than to pictures, and increased leniency was noted for both item types over time. Explanations of the results are offered in terms of differences in initial encoding and of a loss of discrimination between experimental and extraexperimental materials.     

Further examinations of the category-recall function

Subjects were assigned to use either three or six categories and were given either 5 or 10 trials in a word-sorting task. Subsequent to sorting, they recalled as many words as they could. A measure of sorting consistency showed that the six-category sort was a more difficult task than was the three-category sort. Number of categories did not have a significant effect on recall performance regardless of whether 5 or 10 sorting trials were used. A correlational analysis raised questions about the relationship of the sorting tasks to recall performance and clustering.     

The legalization of the school psychologists’ world

Discusses the increasing tendency of legal rules to shape school psychologist's conduct. Court cases, legislation, and empirical studies treating with this issue are analyzed. The article suggests that “the legalization of the school psychologist's world” may afford an opportunity to reshape, in more “non-formal” and collegial ways, relationships with other school professions, students, and parents.     

A probe trial procedure for the study of children's discrimination learning and transfer

A discrimination reversal problem was presented to 192 children varying in age from 3 to 5 years. At the end of both the initial learning and transfer trials, probe trials were introduced to ascertain the response rule describing children's choices. Results were analyzed in terms of a binary division of the children according to their responses to the probe stimuli; children who responded errorlessly (concept responders) were contrasted with children who made errors on the probes (instance responders). Using this criterion, it was found that many children transferred in a way different from the way they learned the initial problem. There was no difference in the proportion of younger and older children responding conceptually to the original problem, but older children were more likely to transfer conceptually when standard geometric blocks were used as stimuli. Future studies must consider the possiblity that learning and transfer may be accomplished by different processes whose application differs with age, the nature of the stimuli, and the stage of training.     

Self-consciousness, self-awareness, and self-attribution

Self-awareness was either manipulated by a mirror (experimental) or not (control). Subjects were selected for being high or low in private self-consciousness (disposition to attend to one's thoughts, feelings, motives). Private self-consciousness had a stronger effect on self-attributions than did self-awareness. These findings have implications for attribution, self-consciousness, and the relationship between manipulations and dispositions.
