Parents tend to modulate their movements when demonstrating actions to their infants. Thus far, these modulations have primarily been quantified by human raters and for entire interactions, thereby possibly overlooking the intricacy of such demonstrations. Using optical motion tracking, the precise modulations of parents’ infant‐directed actions were quantified and compared to adult‐directed actions and between action types. Parents demonstrated four novel objects to their 14‐month‐old infants and adult confederates. Each object required a specific action to produce a unique effect (e.g. rattling). Parents were asked to demonstrate an object at least once before passing it to their demonstration partner, and they were subsequently free to exchange the object as often as desired. Infants’ success at producing the objects’ action‐effects was coded during the demonstration session and their memory of the action‐effects was tested after a several‐minute delay. Indicating general modulations across actions, parents repeated demonstrations more often, performed the actions in closer proximity and demonstrated action‐effects for longer when interacting with their infant compared to the adults. Meanwhile, modulations of movement size and velocity were specific to certain action‐effect pairs. Furthermore, a ‘just right’ modulation of proximity was detected, since infants’ learning, memory, and parents’ prior evaluations of their infants’ motor abilities, were related to demonstrations that were performed neither too far from nor too close to the infants. Together, these findings indicate that infant‐directed action modulations are not solely overall exaggerations but are dependent upon the characteristics of the to‐be learned actions, their effects, and the infant learners. 相似文献

The current study evaluated a toilet-training treatment package described by Greer et al. (2016) with children diagnosed with autism spectrum disorder (ASD). Most of the current research on toilet-training interventions for children with ASD are replications and modifications of Azrin and Foxx (1971) or (more recently) LeBlanc et al. (2005). However, these procedures are composed of components that are not included in studies with typically developing (TD) children. For example, Greer et al. evaluated the effectiveness of three typical components within a toilet-training package, mostly with TD participants: a 30-min sit schedule, placing participants in underwear, and differential reinforcement. The primary purpose of the current study was to replicate and extend the treatment package described by Greer et al. to children with ASD. A secondary purpose was to evaluate modifications necessary for individualized toilet training when the commonly used components were ineffective. The results of Greer et al. were replicated for 11 participants with ASD in the current study, suggesting that intensive toileting interventions (e.g., interventions requiring overcorrection, reprimands, and dense sit schedules) may only be necessary for a subset of individuals with ASD. 相似文献

Differential reinforcement of alternative behavior (DRA) has a long history as a behavioral treatment. The term has usually been defined in a manner that suggests one form of behavior (usually some appropriate alternative) is reinforced, while another form of behavior (usually problem behavior) is placed on extinction. In this paper, we will suggest that DRA should not require extinction, either procedurally or by definition. Ideally, problem behavior would be placed on extinction when possible; however, when problem behavior is not or cannot be placed on extinction, the procedure used is still DRA. Thus, we propose the following definition: Providing greater reinforcement, along at least one dimension, contingent on the occurrence of one form or type of behavior, while minimizing reinforcement for another form or type of behavior. 相似文献

Employees of merging organizations often show resistance to the merger. The employees' support depends on the companies' premerger status and on the merger pattern. Based on an intergroup perspective, three studies were conducted to investigate the influence of premerger status (high, low) and merger pattern (assimilation, integration-equality, integration-proportionality, transformation) on participants' support for a pending organizational merger. Students (Study 1) and employees (Study 2) had to take the perspective of employees of a fictitious merging organization. Study 3 investigated students' perceptions of a potentially pending university merger using a 2 (status) x 3 (merger pattern: assimilation, integration-equality, integration-proportionality) design. Across all studies, the low-status group favored integration-equality and transformation whereas the high-status group preferred integration-proportionality and assimilation. Perceived threat mediated the effects. Legitimacy was a stronger mediator for effects of the low-status group. 相似文献

Negative affect and sensitization to pain 总被引:4,自引:0,他引:4
Janssen SA 《Scandinavian journal of psychology》2002,43(2):131-137
Pain usually has a strong negative affective component, which is believed to modulate pain perception. After reviewing theories on the link between negative affect and pain, mechanisms are discussed by which negative affect may either increase or inhibit pain. Possible pain-inhibiting mechanisms are endogenous opioid release, blood pressure reactivity, and distraction of attention; possible pain-increasing mechanisms are autonomic and muscular reactivity, misattribution of arousal, hypervigilance to pain, worrying, and avoidance behavior. It is emphasized that each of these mechanisms can be very adaptive in acute pain situations to prevent injury and promote recovery. In chronic pain, however, ongoing physiological arousal and hypervigilance to pain, induced or magnified by negative affect, may cause sensitization to pain. Furthermore, worrying about pain and avoidance of pain-inducing activities may increase negative affect, ypervigilance, and functional disability. It is argued that, in the long run, pain-related negative affect has sensitizing and disabling effects. 相似文献

Paul Tillich's eternal now is the ground from which all things emerge and perish in each and every moment. A Tillichean eschatology involves the gathering of all things finite into the eternity of the present moment, into God. Salvation is present moment. But is the “eternal now” enough? This essay offers biblical and theological critiques of Tillich's present eschatology and posits an eschatology that combines Tillich's “eternal now” with Wolfhart Pannenberg's “end‐oriented eschatology.” The result is an eschatology that recognizes the eternal now in which all things (including all time) belong to God yet with an eye toward the God‐given possibilities of the next moment, the future. The end of being is not cessation; rather, it is the fulfillment of time, the consummation of all things. 相似文献

The Colored Ecological and Genetic Relational Map (CEGRM) [pronounced see-gram] is a conceptual approach and tool for presenting information about family and nonkin relationships and stories about inherited diseases in a simple, understandable form. It combines information that can be derived from pedigrees, genograms, ecomaps, and social network analysis in a single, or series of, pictorial maps based on colors and shapes. The CEGRM is based on a social systems perspective, particularly emphasizing social exchange and resource theories. The CEGRM should be particularly useful in genetic counseling research with members of suspected cancer-risk families or families with other late-onset inherited diseases. A genetic counseling client comes with a social history and context as well as a genetic one. Client decision-making in terms of reproductive plans, therapeutic intervention, lifestyle behavior and sharing or withholding of genetic information frequently becomes enmeshed with preexisting psycho-social relationships among biological kin, affinal kin (in-laws) and fictive kin (friends who act as family). The CEGRM makes it easier to compare different types of social interactions between the client and his/her significant others and among family members on the same dimensions. 相似文献
