The influence of labor market discrimination on locus of control

Prior research has established the existence of racial differences in locus of control as well as a relationship between labor market experience and locus of control. This study extends this line of inquiry by examining the relationship between labor market discrimination and subsequent change in locus of control. Drawing on a national probability sample (N = 2857) of young men, multiple regression analysis was used to estimate the effect of labor market discrimination (over a 2-year period) on subsequent locus of control. The results indicate that perceptions of employment discrimination influence the level of externality among blacks, over and above racial identification. Blacks who view themselves as victims of employment discrimination experience twice the increase in externality as blacks reporting no awareness of discrimination.     

Muscle relaxation training for fear reduction of patients with psychological problems: a review of controlled studies

Twenty-four studies of relaxation training for fear reduction of patients with psychological problems, which were published between 1960 and 1980, are reviewed. It is argued that only studies of the outcome of courses are relevant in considering the efficacy of therapy and concluded that such courses are capable of reducing autonomic arousal during training and during rest and stress following the course, capable of reducing behavioural avoidance, and capable of reducing subjective reports of disorder. This fear-reducing effect is less than that of exposure, and future research should examine the value of adding relaxation training to exposure.     

On comprehending idioms: Do children get the picture?

This study examines children's comprehension of idioms. First, third, and fifth grade children (6, 8, and 10 years old) and college adults were read short stories containing contextual information and a key terminal sentence. The contextual information biased either an idiomatic, a literal, or am ambiguous (neutral) interpretation of the terminal sentence. The terminal sentence contained either an idiom (“fix his wagon”) or a changed form (“repair his wagon”) of the idiom. These manipulations were used to determine the role of contextual information and the conventional forms of idioms in idiom comprehension. After each story, the subjects were asked to explain the terminal sentence and to answer a “yes-no” question about the action described in the story. The results showed that idiomatic explanations and interpretations occurred more frequently for the idiom than the changed forms, and that there were strong developmental increases in making idiomatic interpretations of both forms. The results are discussed in terms of two current models of idiom comprehension.     

Behaviorally-based decision-making training for children

A seven-step, behaviorally based, decision-making process was taught to 17 children, age 9–10 years. Each child's decision-making ability was measured before and after training, using two audiotaped stories that described problem situations typically encountered in the school or home. The children were asked to identify the problem, generate alternative solutions, think of positive and negative consequences for each solution, and offer a personal value supporting their decision. As compared to a no-treatment control group, the children receiving the decision-making training obtained significantly greater scores on four of five dependent measures. Implications for teaching decision-making as a self-management skill are offered.     

Putting personal growth into an occupational psychology curriculum

This paper outlines an alternative approach to curriculum design in higher education focusing in particular on the introduction of personal growth into the programme, and on facilitating the selection by students of the optimal choice of options. It is argued that models of curriculum design need to take cognizance of at least four interested parties; and that in the resolutions of their divergent interests, curriculum designers must make clear their most potent values, as well as their theories and assumptions about the nature of learning. A brief outline follows of two courses based upon these propositions. Finally, evaluations by both trainers and students involved in these courses are presented.     

Tune recognition with reduced pitch and interval information

Twenty subjects were tested on their ability to recognize simple tunes from which rhythm information had been removed. Only the first phrase of each tune was presented. The purpose of the experiment was (a) to determine whether stimuli containing only high harmonics can evoke a sense of musical pitch, and (b) to provide a set of data in normal subjects with which the performance of deaf subjects whose auditory nerve is stimulated electrically can be compared. Each subject was tested on five sets of stimuli presented in a counterbalanced order. These stimuli were (I) pulse trains high-pass filtered at 2 kHz, with repetition rates in the range of 100-200 p.p.s.; (2) as in (I) but high-pass filtered at 4 kHz; (3) sinusoids with musical intervals compressed, so that the “octave” was a ratio of I:I·3; (4) sinusoids with the musical intervals expanded, so that the “octave” was a ratio of I:4; (5) sinusoids of a constant frequency in which the normal frequency changes were translated into intensity changes, each semitone being represented by a 3 dB change in level. The results indicate that a pattern of intensity changes does not support tune recognition, and that, although the pitch contour alone allows reasonable performance, subjects do use musical interval information in recognizing tunes. Stimuli containing only high harmonics can provide such interval information, and thus can evoke a sense of musical pitch. Preliminary results from a deaf subject stimulated electrically with an electrode on the surface of the cochlea indicate that such stimulation can also evoke a sense of musical pitch. It is concluded that musical pitch information can be carried in the time-pattern of nerve impulses in the auditory nerve.     

Memory for pictures and words as a function of level of processing: Depth or dual coding?

The experiment was designed to test differential predictions derived from dual-coding and depth-of-processing hypotheses. Subjects under incidental memory instructions free recalled a list of 36 test events, each presented twice. Within the list, an equal number of events were assigned to structural, phonemic, and semantic processing conditions. Separate groups of subjects were tested with a list of pictures, concrete words, or abstract words. Results indicated that retention of concrete words increased as a direct function of the processing-task variable (structural < phonemic 相似文献   

A low-cost interactive coordinate plotter

An inexpensive system for on-line coordinate plotting is described. Users with access to a computer running ALGOL or FORTRAN, and equipped with analog-to-digital converters, can build the system for less than $50. The program is readily modified for the individual user’s requirements, and interactive features allow data correction and analysis to be carried out during coordinate plotting, with operators warned of plotting errors as they occur.
