Comparing the Accuracy of Personality Judgments by the Self and Knowledgeable Others

ABSTRACT In this article we compare the accuracy of personality judgments by the self and by knowledgeable others. Self- and acquaintance judgments of general personality attributes were used to predict general, videotaped behavioral criteria. Results slightly favored the predictive validity of personality judgments made by single acquaintances over self-judgments, and significantly favored the aggregated personality judgments of two acquaintances over self-judgments. These findings imply that the most valid source for personality judgments that are relevant to patterns of overt behavior may not be self-reports but the consensus of the judgment of the community of one's peers.     

Counseling Disruptive Black Elementary School Boys

The assignment was to counsel the 10 worst behaved boys at an inner-city elementary school. This case study illuminates the interplay between theory, practice, and values by describing effective techniques of intervention in a situation that reflects social pathology. Traditional African values and certain principles of character provide a set of reliable standards for improving behavior.     

Computer program for quasi-random stimulus sequences with equal transition frequencies

C language routines are presented for the generation of randomized stimulus sequences constructed from multiple presentations of m stimuli satisfying sequential constraints with respect to the frequencies of the occurrence of n-gram subsequences. Applications are suggested for sequential experiments in which main effects for the present stimulus and the stimuli in the preceding (n?1)-length substring can be tested, as well as the interactions among stimuli at the various positions in the substrings.     

The effect of instruction with relational and item-specific elaborative strategies on young children's organization and free recall

One hundred and sixty second-grade children were assigned on the basis of a free recall pretest to four instruction conditions and were given a series of lists of pictures for free recall. For three groups, the instructions were directed at encoding either (a) list organizational information, (b) item-specific semantic information, or (c) organizational and individual item information, while the fourth group constituted a “No-training” control with standard free recall instructions. The subjects received either related or unrelated lists during the training phase and related or unrelated lists during two post-tests, immediately following and 1 week after training. For both types of lists, instructions emphasizing list organization were more effective than those emphasizing item-specific elaboration. Subjects given individual item elaborative instructions showed levels of recall which were comparable to those of the control subjects. While the combined effect of organizational and individual item processing did not exceed the performance produced by organizational instructions alone, the degree of generalization was greater for subjects processing both kinds of information, especially when subjects received related lists during training.     

Voice change in the stimulus suffix effect: Are the effects structural or strategic?

The literature on the stimulus suffix effect shows that if the suffix is presented in a voice different from that in which the list items are presented, there is less of a decrement in list recall than if the suffix is presented in the same voice. This experiment attempted to answer the question of whether this variable diminishes the suffix effect because of attentional factors or because of structural properties of echoic memory. Subjects received lists of digits in a male voice and either a tone, same-voice suffix, or different-voice suffix. Subjects received either the same suffix for all lists or two different suffixes. Those subjects given two suffixes and those given two tones were either forced to discriminate between them or had no discrimination requirement. The results demonstrated that voice change has both attentions] and structural consequences on the suffix effect, with the attentional factors being confined to the preterminal positions and the structural factors being confined to the last position or two.     

Autoshaping: further study of "negative automaintenance"

The key pecking of pigeons was autoshaped to three key colors paired with food in discrete trials. Then, the effects of three different color-correlated contingencies were compared: reward (presentation of food contingent on pecking), omission (presentation of food prevented by pecking), and extinction (no food). Two measures of performance were used: initial response (the number of trials with each color on which at least one peck was made) and multiple response (the total number of pecks per trial). In general, the reward color produced more pecking than the omission color, the omission color more than the extinction color, and the extinction color more than on blank trials with an unlighted key, although (relative to reward) omission produced a higher level of initial than of multiple responding. These results point clearly to the importance of stimulus-reinforcer continguity in the control of pecking.
