Applied developmental psychology: Problems and prospects for an emerging discipline

Some problems and prospects for the emerging discipline of applied developmental psychology are analyzed. A working definition of applied developmental psychology is offered, along with a categorization scheme which places developmental psychologists along the basic-applied continuum. Some of the tasks that applied developmentalists can perform are listed, followed by a discussion of the boundaries of applied developmental, particularly the boundary with clinical psychology. Next, the training of applied developmental psychologists at the predoctoral and postdoctoral levels is explored. Finally, some of the professional issues that might confront applied developmentalists as the field evolves are described.     

Generalized and lateralized effects of concurrent verbal rehearsal upon performance of sequential movements of the fingers by the left and right hands.

College student subjects performed a sequential typing task requiring bilaterally synchronized movements (Experiment 1) or unilaterally synchronized movements (Experiment 2) singly, and concurrently with silent and vocal rehearsal of verbal lists varying in redundancy. Rehearsal interfered with bilaterally synchronized movements more when the right hand was leading the sequence than when the left hand led, and with movements of the right more than the left hand in unilaterally synchronized movements. Results are interpreted in terms of intrahemispheric and general capacity competition between the concurrent performances.     

Job satisfaction among students in work education programs

Data were collected from 1016 students in grades 9–14 from 50 work education programs. Data were also collected from 696 similar students who held part-time jobs but were not participating in work education programs. Participating students were significantly more satisfied with their jobs than were the nonparticipating students. Group atmosphere, availability of adult role models, meaningfulness of work roles, and availability of feedback accounted for much of the variation in job satisfaction among students.     

A developmental study of attribute encoding in free recall

In two studies, subjects from second-grade, sixth-grade, and college were presented lists of unrelated words for single-trial free recall. Embedded in the list were critical items that were either semantically or phonemically related or else were completely unrelated. The sets of related items were either massed or distributed in the longer list. For second-graders, recall of Phonemic words was better than recall of Semantic words while the reverse was true for sixth-graders. Recall of Semantic distributed words by second-graders and of Phonemic distributed words by sixth-graders did not differ from recall of unrelated words. College students recalled Phonemic and Semantic words equally well and all related words better than unrelated words. Developmental trends were seen in the salience of particular attributes and in the utilization of low salient attributes.     

On signalling that it's your turn to speak

The operation of a “speaker-state signal” in two-person, face-to-face conversations is hypothesized. Display of this signal by an auditor appears to indicate, among other things, that he is claiming the speaking turn, differentiating this action from a “back-channel behavior” by which he merely acknowledges some portion of the speaker's message. The signal also appears to play a part in the resolution of situations in which both participants simultaneously claim the speaking turn. The signal is defined as the display of at least one of a set of four behavioral cues, two in paralanguage and two in body motion.     

Threats and promises: Reputational consequences and transfer of credibility

This study was designed to investigate the reputational consequences of making threats and promises and how they affect subsequent credibility. Eighty-eight high school girls were given predetermined information about the past behavior of their pairmates prior to receiving influence attempts from them. Each first learned that her pairmate had (1) threatened or promised in the past and then learned whether she had (2) fulfilled or failed to fulfill her threat or promise. The subject herself then received a threat or promise from her pairmate. As anticipated, threateners were viewed less favorably than promisers. These impressions were maintained when it was learned that commitments had been fulfilled, but altered decidedly when it was learned that they had not. Credibility or lack of it was found to generalize from threats to promises and from promises to threats only under some conditions. It was concluded that the fit between existing impressions and proclaimed future activity, not a person's record for past reliability, is often the critical determinant of whether or not she is judged to be credible.     

Delay of gratification in children: The effects of training under fixed,decreasing and increasing delay of reward

The effect of fixed, gradually decreasing, or increasing delay of reward in discimination learning on later delay of gratification was investigated. In discrimination training, employing a correction procedure, a candy reward was delivered either after 0, 10, 20, 40 or 60 sec fixed delay; or after 60 sec in the first block of trials and decreased in successive block; or reward was immediate in the first block of trials and delay was gradually increased to 60 sec. In the delay of gratification tests, subjects could press a button immediately to receive a small reward (one candy or a cheap toy) or delay pressing and receive an increasingly larger reward (more candy or a better toy).Learning was not significantly affected by either fixed or decreasing delays. Increasing delays resulted in faster learning than decreasing delays. The increasing delay group demonstrated superior delay of gratification on both tests. Fixed delay groups did not differ significantly among themselves, nor from the decreasing delay group. The effectiveness of exposure to increasing delays in facilitating delay of gratification was interpreted as due to either the acquisition of coping responses or the extinction of frustration.
