A small pilot study was carried out to investigate whether college tutors' perceptions of students' counselling needs were dependent on the gender of the student. Twenty-five tutors were asked to read six vignettes describing composite case-studies of students showing overt distress. The vignettes were constructed to represent two of each of three types of problem (anxiety, depression and aggression). One of each clinical type depicted a female student and the other a male. The tutors were asked to evaluate each of the six vignettes along a visual analogue scale, according to the perceived urgency of the problem and its long-term nature. The results were then analysed using two-factor within-subjects anovas and unplanned multiple pairwise comparisons to establish whether there existed any differences on these dimensions. Of the analyses computed, it was found that depressive vignettes were considered to be in more urgent need of referral than were anxious or aggressive vignettes; that males were generally considered to have a more urgent need for referral than were females; that anxiety was construed as a less enduring problem than was depression or aggression; and that male aggressive vignettes were considered to be a longer-term problem than were females, anxious or depressive clients. These results indicate that some sex-role stereotyping exists with respect to psychological problems. This is discussed in terms of equal opportunities and access to student support systems.  相似文献

Experimentally naive rats were trained to key press on a fixed-ratio 10 schedule of food reinforcement by a completely automatic procedure within a single, 1-hr session. Control procedures demonstrated that the resulting behavior was an operant, under control of the schedule of reinforcement and the specified reinforcing stimulus (food). A simple, combination food-tray operandum, also described, was used as the basis for the training technique.  相似文献

Sixty students, male and female, were used as Ss to test the effect of a 1, 000-Hz, 5-sec tone at 0, 70, and 90 dB, on standing sway. In general, antero-posterior sway was greater than lateral, and males swayed more than females in both directions. In addition, males increased their sway in time, whereas females did not. Only lateral sway in the 5-sec interval after the presentation of the tone increased, and only after 10, 15, and 20 min of standing, with a maximum at 15 min. Amplitude of lateral sway appeared independent of bodily characteristics, and is suggested as being more useful for comparing Ss than is antero-posterior sway.  相似文献

Six 4-year-old Ss were presented with a textual program consisting of 26 words arranged so the word stimuli were gradually combined into sentences and then short “stories.” Three Ss were given the No-Reinforcement condition first, and only social reinforcers were presented. They were switched to the Reinforcement condition as soon as they requested discontinuance of the activity. The other three Ss were given Reinforcement—No Reinforcement—Reinforcement treatments. The No-Reinforcement treatment in this case lasted until S requested discontinuance of the activity. The reinforcers were mixed edibles and trinkets, as well as tokens backed up by small plastic toys on a 1:24 ratio. The unit of response was the number of new texts acquired as a result of each of the 45-min experimental sessions. It was demonstrated that the program, procedure, and reinforcement conditions produced curves which are analogous to those produced in common operant-conditioning procedures. The results indicate that other operant principles may be studied in this significant area of human behavior, with important practical consequences.  相似文献
