Two studies assessed the effects of interagent, inconsistent discipline on aggression in young boys. One agent responded to hitting behavior with verbal disapproval while another agent responded with verbal approval. In Experiment 1, the frequencies of hitting responses of first- and second-grade boys were examined under four schedules of adult reactions: (1) consistent disapproval; (2) consistent ignoring: (3) consistent approval; and (4) inconsistent discipline (approval from one agent and disapproval from the other). Aggressive responding was least frequent when met with consistent disapproval whereas the frequency of hitting responses in the inconsistent discipline condition was not different than that in the consistent approval and ignore conditions. In Experiment 2, the frequencies of hitting responses were examined under a schedule of consistent disapproval following a brief schedule of either: (1) inconsistent discipline; (2) consistent approval; or (3) consistent ignoring. Hitting behavior during consistent disapproval was greatest following a period of inconsistent discipline and least frequent following a history of consistent ignoring. These findings replicate the results of correlational field studies of the relation between inconsistent discipline and aggression in boys. In addition, these experimental studies demonstrate a causal link and the direction of effects between these variables. 相似文献

In three experiments using delayed-matching tasks with 5-year-old children (one of which also included 7-year-olds) no support was found for the hypothesis that children code for line orientation using a match-mismatch strategy. The hypothesis that errors in discrimination of obliques can be attributed mainly to confusion over the left-right direction of tilt was rejected in a fourth experiment. It was concluded that young children do not spontaneously encode orientation in relation to a matching environmental cue and that there is no evidence that memory for the direction of obliquity is inferior to memory for the degree of obliquity. 相似文献

Children, ranging in ages from 7.3 to 9.6 years, were identified according to the type of schemata structure they used to recall picture sequence events. These children were then required to recall several written text passages representing four different conditions: (1) theme first paragraphs, (2) theme final paragraphs, (3) paragraphs with no theme but having thematic structure, and (4) paragraphs with no theme and no thematic structure. It was found that the manner and the amount of the child's recall were a function of how the child's schemata structure interacted with a given paragraph structure. The implications of these findings are discussed in terms of the generally unquestioned assumption that only one “ideal” text grammar is needed to describe children's schemata for processing test. 相似文献

Experiment 1 studied the effect of several Pavlovian appetitive conditioning procedures on rats' headpoking into a food tray (goal tracking). The procedures included forward delay conditioning, CS-alone extinction, differential conditioning, and simultaneous compound conditioned inhibition training. In general, the headpoke behaved in all of these treatments much like a Pavlovian CR; however, one could also say that the headpoke behaved like an adventitiously reinforced operant for which the CS was an SD. Experiment 2, therefore, used the differential-nondifferential technique (E. Gamzu & D. R. Williams, Science, 1971, 171, 923–925), and Experiment 3 used an omission technique (F. D. Sheffield, in W. F. Prokasy, Ed., Classical conditioning, New York: Appleton-Century-Crofts, 1965; D. R. Williams & H. Williams, Journal of the Experimental Analysis of Behavior, 1969, 12, 511–520), to try to separate the role of stimulus-reinforcer and response-reinforcer relations in controlling the headpoke. These techniques proved inadequate. The results of Experiment 2 could be given either operant or Pavlovian interpretations. Those of Experiment 3 showed that headpoking is dominated by response-reinforcer, rather than by stimulus-reinforcer, relations when the two compete but forced no conclusion about which dominates when the two act together as in acquisition. Implications for pigeon autoshaping are discussed. 相似文献

Six adult, human female volunteers participated in a study to determine the consistency of their pattern of sexual arousal to two erotic films over two experimental sessions. Sexual arousal was assessed objectively by means of continuous measurement of temperature changes of the labia minora and subjectively by periodic self-ratings. Each subject developed increases in labial temperature to both film presentations that ranged from about 0.10°C to 1.36°C above basal levels. The amount of temperature change in a subject's labia minora during the first film presentation was significantly correlated with that during the second film, and there was a reasonable degree of consistency across the two sessions with regard to the rate at which the subject's labial temperature subsided towards basal levels after the cessation of erotic stimulation. Labial temperature changes and subjective ratings were also significantly correlated during each of the two film presentations. 相似文献

This work presents a new conceptualization of the contrast between holistic and differentiated perception of multidimensional stimuli. Specifically, two hypotheses about the experiential status of dimensions within holistic perception are proposed and tested as explanations of young children's general perceptual mode and adults' integral mode. The major result is that three levels of dimensional status are realized: (1) the hypothesis of nonprimary axes characterizes adult “integral” perception of saturation and brightness relations, (2) the hypothesis of primary but not mandatory axes characterizes kindergarteners' “integral” perception of size and shade relations, and (3) the notion of mandatory axes characterizes adults' separable perception of size and shade relations. These results indicate a new interpretation of the integrality-separability distinction and the derivative developmental hypothesis. It is specifically hypothesized that the developmental history of most dimensional combinations includes these three levels. 相似文献

Male and female black undergraduates enrolled in Introductory Psychology and Human Development courses at a predominantly black university responded to five stories about married black physicians whose total income was greatest, respectively, when the husband cared for the children (Story 1), the wife cared for the children (Story 2), either spouse cared for them (Story 3), the wife earned more than the husband (Story 4), or the husband earned more than the wife (Story 5). In contrast to the results of a study completed at a predominantly white university, black females favored maternal child care even when, as a result, the family income was reduced and had significantly less of a preference for higher relative salary for the wife than did females in the study at a predominantly white university; although black males preferred maternal child care in Story 2 and Story 3, the preference was significantly less than that of males in the study at a predominantly white university. The results were discussed in terms of their relevance to collaborating career patterns among middle-class black families. 相似文献
