A functional measurement analysis of the development of dimensional coordination in children

The development of children's dimensional coordination was investigated using kindergarten, second, fourth, and sixth grade subjects (Ages 5, 7, 9, and 11 years, respectively), and an adult sample, by means of a perceptual estimation task requiring the subjects to match in total area a stimulus rectangle to an adjustable square stimulus. The problem was formulated using information integration theory, and the procedures and techniques of functional measurement were used in the analysis. Dimensional coordination was found to develop from a stage of total centration on one dimension to a stage of total decentration with equal weighting applied to both dimensions.Contrary to extant hypotheses, the vertical dimension was not the salient dimension for single dimension centerers. Rather, the spatial axis on which the compared-objects were placed determined the displacement of attention. When this frame of reference effect was controlled, the longer of the two dimensions was the salient dimension for centering subjects.     

Age changes in nonverbal decoding as a function of increasing amounts of information

A test of nonverbal decoding skill (the PONS test) was administered to 632 subjects of eight different age levels, ranging from third graders to adults (Ages 8–33 years). Females were more accurate than males, older subjects were more accurate than younger ones, and all samples tended to decode more successfully when more information was available. Three different analyses showed that the increase in accuracy with increasing amounts of information was more pronounced for the older than for the younger groups. This differential effectiveness in the utilization of available information was discussed in terms of processing capacity, effort, and strategies for sampling a diversity of cues.     

Training children's self-control: A field experiment in self-monitoring and goal-setting in the classroom

A field experiment investigated the effects of training in self-monitoring and goal-setting skills on classroom study behavior and academic achievement among elementary school students in an individualized mathematics program. In the Self-Monitoring Conditions, students were shown a simple system for observing and maintaining daily records of their own study behavior during their math classes; orthogonally, in the Goal-Setting Conditions, students were shown a simple method of setting and recording daily performance goals during their math classes. Exposure to self-monitoring procedures produced significant increases in both appropriate study behavior and in actual achievement in the mathematics program, while exposure to goal-setting procedures had no effect on either study behavior or academic achievement. Nor, contrary to expectation, did exposure to the goal-setting instructions enhance the effectiveness of the self-monitoring system. The implications of these results in terms of implicit and explicit models of self-reinforcement processes were discussed.     

Developmental constraints associated with children's use of the keyword method of foreign language vocabulary learning

Second- and sixth-grade (ages 7 and 11 years, respectively) subjects were instructed to learn simple Spanish vocabulary nouns using the keyword method. To remember a foreign word translation the keyword method user must: (1) associate the foreign word to an English word (the keyword) that sounds like part of the foreign word; and (2) remember an image of the keyword and translation referents interacting. Second-grade keyword users who were provided with interactive pictures remembered more vocabulary items than those who generated their own imagery links when given separate pictures of the keyword and translation referents. Second graders who generated their own linking images when given only the keywords and translation words recalled fewer items than both picture groups, and were not significantly different from control subjects. Sixth graders in the three imagery-link variations performed at comparable levels and better than control subjects. The results are in complete accord with previous speculations about the development of imagery strategies in children.     

The effect of serving as a model of self-control on subsequent resistance to deviation in children

The effect of having a child serve as a rule-following model for other children on the model's own subsequent rule-following was investigated in a resistance to deviation situation. First- and second-grade boys (age range 73 to 94 months) who were told they would serve as self-controlling models for others and who actually served in this capacity touched prohibited toys less than did boys who were not told they would serve as models. Boys told they were to serve as models but who were prevented from performing deviated at a level between the models and boys given no responsibility. Having children serve as rule-following models for others is suggested as an effective, non-punitive technique to increase their self-control.     

Visual behavior of the young human infant: Relationships between chromatic and spatial perception and the activity of underlying brain mechanisms

Two experiments investigated visual attention in human infants. In one experiment, babies looked longer at more than at less saturated colors. In a second experiment, babies looked longer at gratings aligned along the horizontal and vertical orthogonals than along the obliques. Because saturated colors and orthogonal stimulation elicit greater activity in visual system neurons and greater amplitude evoked potentials than desaturated colors or oblique stimulation, these two experiments support the hypothesis that the simple visual stimuli to which infants preferably attend are those that are particularly appropriate in stimulating the geniculostriate or primary visual system. The ethological significance of this taxic mechanism and its utility and function in perception, cognition, and aesthetics are underscored.     

Social influence on attitudes and on anchoring of congeneric attitude scales

Criteria for distinguishing between attitude and response scale effects in “after-only” studies of source-recipient discrepancy were developed and applied in two experiments. These criteria refer to congeneric scales (i.e., multiple measures of the the same property, which may differ in origin, unit, and reliability). Persuasive information may function as a scale anchor, in which case it is expected to affect only that response scale to which it directly pertains. Alternatively, it may convice recipients to change attitudinal positions, and produce effects on all congeneric scales. In one experiment, the self-proclaimed leniency-sternness of a presiding judge in a manslaughter case was varied along with the sentence he imposed and his trustworthiness. In the second study, only the sentence was manipulated, while both leniency ratings and sentencing were measured as dependent variables. Both analyses revealed support for the response scale interpretation, in that effects were observed only on those scales that were directly manipulated.     

Attitudinal qualities relating to the strength of the attitude-behavior relationship

A study was conducted to examine the relation between each of several attitudinal qualities and attitude-behavior consistency. Subjects' attitudes toward volunterring to participate in psychological research were assessed. The number of experiments in which each subject volunteered to participate was employed as the measure of behavior. Attitude-behavior consistency was significantly related to (1) the amount of direct experience upon which the subject's attitude was based (specifically, the number of experiments in which the subject had previously participated), (2) the degree of certainty with which the attitude was held, and (3) how well-defined the subject's attitude was, as measured by the width of his latitude of rejection. These three attitudinal qualities were significantly intercorrelated, suggesting that direct experience with an attitude object may produce an attitude that is both better defined and more confidently held than an attitude formed through more indirect means.
