Domestic hens responded under multiple fixed‐ratio fixed‐ratio schedules with equal fixed ratios. One component provided immediate reinforcement and the other provided reinforcement after a delay, signaled by the offset of the key light. The components were presented quasirandomly so that all four possible transitions occurred in each session. The delay was varied over 0, 4, 8, 16, and 32 s with fixed‐ratio 5 schedules, and over 0, 8 and 32 s with fixed‐ratio 1, 15 and 40 schedules. Main effects of fixed‐ratio value and delay duration were detected on between‐ratio pauses. Pauses were longer when the multiple‐schedule stimulus correlated with a delayed‐reinforcer component was presented, with the longest pauses occurring at the transition from a component with an immediate reinforcer to one with a delayed reinforcer. Pause durations were shortest during immediate components. Overall, both the presence or absence of a delay in the upcoming component, and the presence or absence of a delay in the preceding component affected pause length, but the upcoming delay had the larger effect. Thus changes in delay had similar effects to past reports of the effects of changes in response force, response requirement, and reinforcer magnitude in multiple fixed‐ratio fixed‐ratio schedules.  相似文献

This article articulates some of the problems that surround the use of the term trauma in psychoanalytic theory and suggests that the key element for a theory of pathogenesis and mental functioning is not the either/or of external versus internal causation or trauma versus drive. Rather, it is an understanding of whether, or to what extent, the raw data of existential experience is or is not transformed into psychological experience. From this perspective, trauma is whatever outstrips and disrupts the psyche’s capacity for representation or mentalization. Absent the potential for mental representation, these events and phenomena are historical only from an external, third-person perspective. Until they are mentalized, they remain locked within an ahistorical, repetitive process as potentials for action, somatization, and projection.  相似文献

Consistency and transitivity are important and leading research topics in the study of decision‐making in terms of pairwise comparison matrices. In this paper, we search for conditions that, in case of inconsistency, guarantee ordinal compatibility between ordinal ranking (actual ranking) derived from a transitive matrix and cardinal rankings provided by the most usual priority vectors proposed in the scientific literature. We provide the notion of weak consistency; it is a condition weaker than consistency and stronger than transitivity and ensures that vectors associated with a matrix, by means of a strictly increasing synthesis functional, provide a preference order, on the related set of decision elements, equal to the actual ranking. This notion extends, to the case in which the decision‐maker can be indifferent between two or more alternatives/criteria, weak consistency introduced in previous papers under constraint of no indifference. Finally, we introduce an order relation on the rows of the matrix, that is, a simple order if and only if weak consistency is satisfied; this simple order allows us to easily determine the actual ranking on the set of decision elements.

In this paper I argue against Brandom's two‐ply theory of action. For Brandom, action is the result of an agent acknowledging a practical commitment and then causally responding to that commitment by acting. Action is social because the content of the commitment upon which one acts is socially conferred in the game of giving and asking for reasons. On my proposal, instead of seeing action as the coupling of a rational capacity to acknowledge commitments and a non‐rational capacity to reliably respond to these commitments, we should see action as the coupling, or potential coupling, of a capacity to reason practically and a capacity to act on habits and bodily skills. In putting forward this alternative model of action, I aim to replace Brandom's rationalist brand of Pragmatism with a more classical kind, one that will let us see action as social not only at the level of reasons but also at the level of bodily habits and skills.  相似文献

In my response to the commentaries by Anthony Bass, Irwin Hirsch, and Margaret Crastnopol, I focus on conscious and unconscious factors that open or close potential space across relational realms, including that of analyst and patient, parent and child. I then extend these notions to the supervisory relationship. I describe how these issues affected the writing process for me, and explore the impact that writing has had on the ongoing treatment with my patient. I consider too the ways in which shame travels intersubjectively, shutting down transitional space and interfering with aliveness, authenticity, and creativity.  相似文献

The current study evaluated the effects of a teacher-conducted play intervention on preschool-aged children’s compliance in child care settings. Study participants included 8 children ranging in age from 3 to 5 years and 5 early childhood education teachers within 5 classrooms across 5 child care centers. A combination ABAB and multiple baseline design was used to demonstrate the effects of the play intervention. Pretreatment observations revealed varying degrees of child compliance difficulties. The play intervention was associated with improved rates of compliance for each participant child. The intervention is discussed with regard to its potential as a proactive, nonintrusive strategy for improving young children’s classroom compliance.  相似文献
