Counselor education programs and professional associations of behavioral and social sciences have failed to assist counselors, teachers, and parents in understanding and relating to youth in this technological era. Rebelliousness, alienation, and even rioting engaged in by youth represent cries for help to which adults respond, sometimes with indifference but more often with confusion, resentment, or active antagonism. Empathic and informed counselors may be able to reduce the basic feeling of guilt that leads to such negative reactions by helping school staff and parents recognize that rapid and dramatic changes in modern society have irrevocably influenced attitudes, values, and behaviors of youth. Youth have much right on their side. However, they need wisdom of perceptive adults to guide them in working in acceptable ways for legitimate goals which the older generation has preached but often disregarded in practice. “There is, of course, a teenage problem, but that problem is not the teenager but the adult.”—Ashley Montagu.  相似文献

Two groups of 12 Ss were shown tachistoscopically 4 letters and 4 numbers. Within these alpha-numeric sequences, three variables were systematically manipulated: grouping of items, initial item, and familiarity of the letter sequences. One group of Ss reported first letters then numbers from each sequence; the other group reported numbers then letters. The results indicated that grouping, redundancy, and order of report had significant effects on letter accuracy but not on number accuracy. These effects were interpreted in terms of processing, particularly the use of spatial and identity information during recognition.  相似文献

The Pulfrich pendulum was evaluated as a potential screening device for the detection of anomalies of binocular vision. For this purpose, a booth was set up at the Kentucky State Fair (1964) and the general public invited to observe the pendulum and record their responses with the equipment provided. The obtained results indicate that a dichotomy can be achieved between those who have binocular vision and those who do not. However, gradations of binocular vision from poor to good cannot be achieved with the pendulum as presently understood. Contrary to explanatory theory the characteristic shape of the seen pendulum path was asymmetrical following the rule that the path was displaced away from the observer on the side of the filtered eye.  相似文献

Recall of auditory narrative material was measured under three conditions of presentation. These were a single source condition with material from one speaker, a four source fixed sequence condition with material from four speakers in a fixed sequence of 3-sec. lengths, and a four source random condition with material from four speakers in a random sequence of 3-sec. lengths. Recall was better for the single source condition than for the four source conditions. No significant difference was found between the fixed and random sequential presentations. Results are discussed in terms of the attentional behaviors involved in the tasks.  相似文献
