These experiments were performed to examine the effects of different types of primes across variations in prime set size, prime strength, and prior study in verification and lexical decision tasks. The primes consisted of taxonomic category names, associates, or rhymes that defined either small or large sets of related concepts, and they were either strongly or weakly related to their targets. Targets either were or were not studied prior to the priming task. The results indicated that, for taxonomic primes, shorter decision latencies were obtained when set size was smaller and when the target was studied before the priming task. In contrast, for rhymes, neither set size nor prior study had reliable effects. For all three types of primes, decision latencies were faster for stronger than for weaker prime-to-target relationships. These findings are contrasted with the results of manipulating these variables in episodic tasks such as cued recall, and they are interpreted in the context of a components-of-processing approach. 相似文献
ABSTRACT In this article, we report investigations of four role-playing experiments and one laboratory manipulation that examine the effects of confession on forgiveness and other related judgments. The basic paradigm in the simulation studies was to reveal that a political figure or student in a class confessed either following or not following an accusation, or denied personal responsibility for the act. Among the variables manipulated were the attributions for the wrongdoing and the spontaneity of the confession. The dependent variables in one or more investigations included the perceived personal character of the trangressor, attributions of responsibility for the act, affective reactions of sympathy and anger, forgiveness, and behavioral judgments such as sanctioning and voting likelihood. In the laboratory manipulation study, a mixed-motive game setting was used in which a confederate confessed to having prior knowledge that resulted in his winning the game. We then examined whether this admission influenced subsequent cooperation and competition, as well as the other players' perceptions of the confederate's personality and character. Confession was found to have strong beneficial effects, particularly when given without a prior accusation and in ambiguous causal situations. 相似文献
Successive positive and negative contrast effects in consummatory behavior were investigated following shifts in sucrose concentrations in nondeprived subjects. Forty-four male albino rats were given daily 5-min access to either a 4%- or 32%-sucrose solution across a 14-day preshift period. Subjects in each group were then assigned to either a control or shifted condition. Shifted groups were upshifted (4–32%) or downshifted (32–4%) for a 10-day postshift period. Negative contrast was apparent in both lick rate and time spent at the drinking tube across the first 4 days of postshift. Positive contrast effects were not obtained, but rather a significant effect opposite to positive contrast occurred. The improbability of the ceiling effect explanation for the present results is discussed. Differences relative to deprivation state and the role of perceptual (taste) factors in contrast effects are also examined.
The medical treatment in utero of human beings raises several ethical questions. I argue that treatment is sufficient to establish the fetus as person; and consider how conflicts between the interests of the fetus and mother are to be resolved when such treatment is proposed. My arguments rest upon a 'relational model' of ethical discourse derived from H. Richard Niebuhr's "ethics of the fitting." I conclude that the limitation of personal autonomy is rarely justified, but may be when direct, grave, harm to others is imminent; and that educative rather than punitive measures are the best prospect for protecting fetal life. 相似文献
Recent research shows that aversion conditioning produces conditioned aversions to target stimuli. Conditioned aversions are manifest in the following posttreatment changes in Ss' responses to target stimuli: increased negative evaluations, decreased contact or consumption, and increased phasic heart-rate responses (HRRs). Research on aversion therapy for additive disorders reveals that HRR is a particularly important index of therapeutic change as it is predictive of latency to relapse to drug use. We speculate that aversion conditioning increases Ss' fear and repugnance of target stimuli, that HRRs accurately reflect such defensive responses and that magnitude of defensive response is positively related to latency to relapse. In addition to defensive responding, we believe that HRRs may reflect coping-response or active-avoidance information processing. 相似文献
Pica is a life threating form of challenging behavior displayed by individuals with intellectual and developmental disabilities. In most cases, pica is maintained by automatic reinforcement. Common interventions for pica use some combination of response blocking, response interruption and redirection (RIRD), differential reinforcement of alternative behavior (DRA), and noncontingent reinforcement with competing stimuli. However, there is need for additional research regarding DRA procedures that emphasize skills acquisition by teaching alternative behaviors that modify the established behavioral chain of pica responses that occur in the presence of non-edible stimuli. There is also a need to examine the generality of recent advances in competing stimulus assessment (CSA) methodologies—namely, the augmented-CSA (A-CSA)—to pica. Thus, the purpose of the present investigation was to systematically replicate and extend previous research for the assessment and treatment of pica in an individual with IDD. First, we conducted a functional analysis to identify environmental variables associated with pica. Next, taught Patrick a differential response (i.e., discard pica items in trash receptacle) to earn reinforcers in conjunction with a RIRD procedure. Finally, we conducted an A-CSA for pica. Overall, low rates of pica were maintained over time with a combination of these procedures, and treatment was generalized across settings and people. 相似文献
Although sexual violence and economic distress are often understood and responded to as individual problems, they are rooted in and must be understood within the social systems of patriarchy and advanced global capitalism, both of which normalize these traumas. The problem is that social systems divert guilt for structural sin onto individuals in the form of shame, which I argue is the misplaced debt of structural sin. Through narrative and analysis, I demonstrate the problems of silence, judgement, and death associated with the misplaced debt of shame in structural sin. Preliminarily, I suggest that the theology of the cross enables Christians to name structural sin for what it actually is; judge who or what is truly guilty; and remove shame and guilt from survivors to foster flourishing. 相似文献
