The purpose of the present study is to examine the patterns of depressive response of adolescents on The Beck Depression Inventory (BDI). Subjects, who were registered at the Western Québec Regional School Board (Grades 7–12), completed the BDI in the context of intact classes. Out of 1015 subjects, 249 (152 females, 97 males) met the cut-off score of 15 and above on the BDI, and were retained for the study. Sixty-three percent were francophone and 37 percent were anglophone. Ages ranged from 12 to 17 years. Results did not reveal any difference in the BDI scores as a function of either sex, age, or language. However, a significant discriminant function was obtained from subjects' responses that correctly differentiates depressed males from depressed females in 67.8% of the cases. These differential patterns of depressive responding are compared with those observed in depressed college students and adult psychiatric patients, and discussed in light of the literature on adolescent depression.This is an extended version of a poster paper presented at the 48th annual meeting of the Canadian Psychological Association, Vancouver, June 1987. 相似文献

In Study 1, female subjects received information suggesting either that a stranger (a female accomplice) shared their attitudes and evaluated them positively or that a stranger did not share their attitudes and evaluated them negatively. These procedures took place in the presence of a low (ambient) or high level of negative ions. On the basis of previous research, it was predicted that a high level of negative ions would intensify subjects' reactions to the stranger, thus enhancing their evaluations of her when she seemed to share their attitudes and to like them, but reducing these evaluations when she did not share their attitudes and disliked them. Results offered support for these predictions. In Study 2, female subjects performed two tasks (letter and digit copying) in the presence of a low or high concentration of negative ions. Their blood pressure and pulse were measured at several points during the experiment. Results indicated that on various trials both systolic and diastolic blood pressure were higher in the high-ions than in the low-ions condition. In addition, subjects reported higher levels of subjective arousal and made significantly more errors on the letter-copying task in the presence of a high concentration of negative ions. Together, the results of these studies were interpreted as offering support for the view that high concentrations of negative ions can increase both physiological and psychological (subjective) arousal. 相似文献

Two studies examined the correlates of reasoning ability on a syllogistic reasoning task in subjects who lacked formal background in logic. The main issue addressed was the extent to which reasoning proficiency arises from the consideration of multiple possible set relations (mental models) as opposed to explicit or implicit reliance on deduction rules. Evidence for the use of both models and rules was obtained. Although "good" and "poor" reasoners differed even when time constraints were imposed (consistent with the supposition of a better set of rules among good reasoners), good reasoners showed more improvement and chose to take longer amounts of time when time constraints were removed, suggesting that they considered more alternatives than did the poor reasoners. A comparison between these two groups and a third group of subjects, graduate students who had studied logic, reveals striking differences in both accuracy and speed. 相似文献

Chained schedules of avoidance: Reinforcement within and by avoidance situations 总被引:2,自引:2,他引:0 下载免费PDF全文
Four rats were exposed to chained schedules with variable-cycle avoidance in both links. Responding in the initial link cancelled shocks scheduled once per minute and, according to a conjoint fixed-ratio schedule, produced a terminal link where scheduled shock rates varied from 0 to 8 shocks per minute in different conditions of the experiment. Response rates in the terminal link increased as a function of the scheduled shock rate. Response rates in the initial link, on the other hand, decreased as a function of the shock rate actually received (rather than scheduled) in the terminal link. While consistent with other studies of aversive control, these results differ from those obtained in chained schedules of positive reinforcement in that increases in reinforcement within the terminal link of the chain did not systematically increase the reinforcing value of that link. 相似文献

A field experiment was conducted to examine the influence of invasions of personal space and invader's apparent need upon subsequent helping. On the basis of previous research, it was predicted that helping would be inhibited by invasions of personal space when the invader's apparent need for assistance was low, but would actually be facilitated by such intrusions when his/her apparent need for assistance was high. Results offered support for both of these predictions. Additional findings suggested that these differential effects of invasions of personal space may have stemmed, at least in part, from the induction of contrasting affective reactions among subjects under conditions of low and high apparent need. 相似文献

Reinforcement of human observing behavior by a stimulue correlated with extinction or increased effort 总被引:4,自引:4,他引:0 下载免费PDF全文
Young men pulled a plunger on mixed and multiple schedules in which periods of variable-interval monetary reinforcement alternated irregularly with periods of extinction (Experiment 1), or in which reinforcement was contingent on different degrees of effort in the two alternating components (Experiment 2). In the baseline conditions, the pair of stimuli correlated with the schedule components could be obtained intermittently by pressing either of two observing keys. In the main conditions, pressing one of the keys continued to produce both discriminative stimuli as appropriate. Pressing the other key produced only the stimulus correlated with variable-interval reinforcement or reduced effort; presses on this key were ineffective during periods of extinction or increased effort. In both experiments, key presses producing both stimuli occurred at higher rates than key presses producing only one, demonstrating enhancement of observing behavior by a stimulus correlated with the less favorable of two contingencies. A control experiment showed that stimulus change alone was not an important factor in the maintenance of the behavior. These findings suggest that negative as well as positive stimuli may play a role in the conditioned reinforcement of human behavior. 相似文献

Politicians are increasingly able to communicate their values, attitudes, and concerns directly to voters. Yet little is known about which of these signals resonate with voters and why. We employ a discrete choice experiment to investigate whether and which social-psychological attitudes predict how adult British voters respond to corresponding attitudinal signals communicated by candidates in hypothetical social media posts. For all attitudes studied, covering social feelings (trust, collective nostalgia), social perceptions (nationalism, populist sentiment), and social commitments (national identification, authoritarianism, egalitarianism), we find that participants are much more likely to vote for candidates who signal proximity to their own attitudinal position and less likely for candidates who signal opposing views. The strongest effects were observed for national identification, authoritarianism, and egalitarianism, indicating the importance of commitment to a shared group and to particular principles for distributing power and resources within and between groups. We further demonstrate that social-psychological attitudes are not acting as mere proxies for participants' past votes or left–right ideology. Our results extend adaptive followership theory to incorporate preferences concerning intragroup coordination and intergroup hierarchy, while highlighting the social-psychological dynamics of political communication that may transcend the concerns of particular election cycles. 相似文献

Reaction times of younger and older men: effects of compound samples and a prechoice signal on delayed matching-to-sample performances. 总被引:1,自引:1,他引:0 下载免费PDF全文
Five younger (18 to 23 yrs) and five older (65 to 73 yrs) men were exposed to a series of immediate and delayed (0 to 15 seconds) matching-to-sample problems. Presentation of the pairs of delayed comparison stimuli was either signaled or unsignaled, and the sample contained either 1, 2, or 3 elements, one of which appeared as the positive stimulus. During initial sessions, unlimited time was available to respond. Subsequently, correct responses were reinforced only if they occurred within a specified time limit. A general finding was slower responding with increased delay and with increased number of sample elements. These effects were reduced when the comparison stimuli were signaled and when time limits were in effect. Errors increased as a function of the manipulations of sample complexity and time limits, but did not change systematically when the delay between sample and comparison stimuli was varied. Although the younger men generally responded more quickly than the older ones, men of both ages showed increased speeds when limits were placed on response time, and these changes were maintained when the temporal contingencies were removed. 相似文献
