We examined the extent to which different sounds functioned as motivating operations (MO) that evoked problem behavior during a functional analysis for two participants. Results suggested that escape from loud noises reinforced the problem behavior for one participant and escape from arguing reinforced problem behavior for the other participant. Noncontingent delivery of preferred music through sound‐attenuating headphones decreased problem behavior without the use of extinction for both participants. We discuss the results in terms of the abolishing effects of the intervention. 相似文献

Highly creative advertisements are the end-products of creativity in advertising, and their creation is generally thought to be driven by strategic planning. Thus, 534 Clio-awarded advertisements from the years 2011–2014 were content-analyzed to determine whether implications of two popular planning frameworks, functional matching and the Foote, Cone, and Belding Planning Model, were present in the industry’s best creative work. Since 1960, the Clio Award Program has annually recognized the world’s most creative advertisements. Clio-awarded advertisements are selected by panels of advertising experts specifically constituted to offset gender and country of origin bias. The study found that implications of the two planning frameworks were not present in the industry’s most creative work: types of value-expressive appeals were more frequent than types of utilitarian appeals in Clio-awarded advertisements, regardless of the nature of the advertised products or the category of media used to deliver product messaging. These findings support previous research, which found that highly creative advertising rarely is based on strategic considerations. However, they were inconsistent with other research regarding the presence of the two planning frameworks in general TV advertising. 相似文献

Increasing data suggest that for medical school students the stress of academic and psychological demands can impair social emotions that are a core aspect of compassion and ultimately physician competence. Few interventions have proven successful for enhancing physician compassion in ways that persist in the face of suffering and that enable sustained caretaker well-being. To address this issue, the current study was designed to (1) investigate the feasibility of cognitively-based compassion training (CBCT) for second-year medical students, and (2) test whether CBCT decreases depression, enhances compassion, and improves daily functioning in medical students. Compared to the wait-list group, students randomized to CBCT reported increased compassion, and decreased loneliness and depression. Changes in compassion were most robust in individuals reporting high levels of depression at baseline, suggesting that CBCT may benefit those most in need by breaking the link between personal suffering and a concomitant drop in compassion. 相似文献

In the present study, we investigated whether salience determines the sequence of selection when participants search for two equally relevant visual targets. To do this, attentional selection was tracked overtly as observers inspected two items of differing physical salience: one a highly salient color singleton, and the other a less salient shape singleton. Participants were instructed to make natural eye movements in order to determine whether two line segments contained within the two singletons were oriented in the same or in different directions. Because both singleton items were task-relevant, participants had no reason to inspect one item before the other. As expected, observers fixated both targets on the majority of trials. Critically, saccades to the color singleton preceded saccades to the less salient shape singleton on the majority of trials. This demonstrates that the order of attentional object selection is largely determined by stimulus salience when task relevance is equated. 相似文献

Christie and Klein () demonstrated that a familiar item (word) rapidly attracts attention when presented simultaneously with an unfamiliar item (nonword). However, this finding has never been replicated. The current study is an attempt at such a replication. Participants were presented a familiar word and unfamiliar nonword in the experimental condition. At varying times after stimulus onset one of the items moved, and the participant reported the direction of the movement. A replication of Christie and Klein would be obtained if performance was better for movement discrimination of the familiar item shortly after onset but not at later intervals. The original finding was replicated in fast participants while slower participants show a different effect. A potential individual difference variable is suggested to explain this difference between the fast and slow participants. 相似文献

Smith-Lemli-Opitz syndrome (SLOS, RSH/SLO syndrome, MIM 270400) is an autosomal recessive multiple malformation/mental retardation syndrome initially described by Smith et al. [1964] that is due to a defect in cholesterol biosynthesis. The behavioral phenotype of Smith-Lemli-Opitz syndrome demonstrates cognitive abilities from borderline intellectual functioning to profound mental retardation, sensory hyperreactivity, irritability, language impairment, sleep cycle disturbance, self-injurious behavior, and autism spectrum behaviors. In a recent study of 28 subjects, 14 subjects (50%) with SLOS also exhibited the behavior of throwing themselves backward in a characteristic upper body movement ("opisthokinesis") and 2 adolescents had a stretching motion of the upper body accompanied by hand flicking [Tierney et al., 1999]. In that same study, 6 of 13 subjects (46%) met the Autism Diagnostic Interview-Revised (ADI-R) algorithm criteria (Lord et al. [1993] Infant Mental Health 14:234-252; Lord et al. [1994] J Autism Dev Disord 24:659-685) and the Diagnostic and Statistical Manual (APA [1994] DSM-IV) diagnostic criteria for autistic disorder. Smith-Lemli-Opitz syndrome is a metabolic disorder that is associated with autism. MRDD Research Reviews 2000;6:131-134. 相似文献

Adaptive motor actions require prior knowledge of instrumental contingencies. With practice, these actions can become highly automatic in nature. However, the molecular and anatomical substrates mediating these related forms of learning are not understood. In the present study, we used in situ hybridization to measure the mRNA levels of two immediate early genes (IEGs) in an instrumental paradigm where rats learned to lever-press for food. We report that after three training sessions, Homer 1a and Zif268 (an effector and regulatory IEG, respectively) were significantly induced within an extensive corticostriatal network relative to untrained controls. With extended training (23 sessions), however, a shift in the expression patterns of the two genes was evident. Expression of Homer 1a (official symbol Homer1) decreased significantly in frontal and cingulate cortices, whereas striatal expression was generally maintained. Interestingly, Homer 1a expression markedly increased with extensive training in the ventrolateral region of the striatum (VLS) relative to early learners, suggesting that plasticity in the VLS is required for the efficient production of the learned behavior or in habit formation. Zif268 (official symbol Egr1) expression generally decreased with extensive training; however, these changes were not significant. These results demonstrate for the first time, on a molecular level, a dynamic shift in the contribution of corticostriatal systems mediating the early acquisition and consolidation of goal-directed responses to those engaged after extensive training. 相似文献

Visuospatial learning and memory impairments are an early marker for age-related cognitive decline and Alzheimer's disease. Similar to humans, aged dogs show visuospatial learning and memory deficits (). One hundred and nine beagle dogs ranging between 0.25 and 11.99 years were tested on a visuospatial delayed non-matching to position (DNMP) task to better characterize the progression of visuospatial deficits in the dog. Age predicted 48.2% of the variability in learning the DNMP, with dogs ranging from 1 to 11.99 years generally making more errors with increasing age. By contrast, puppies (<1 year) likely were showing developmental deficits, possibly due to an immature prefrontal cortex. Mild visuospatial deficits were detected by 6 years, which precedes the typical onset of amyloid-beta (Abeta) accumulation in the dog brain by two years, and can serve as an early marker for cognitive decline in the dog. These findings suggest that (1) age-related changes in visuospatial function in the dog models that seen in humans, further validating the dog as a model for human aging and dementia; and (2) other mechanisms, such as oxidative stress, soluble Abeta oligomers or cholinergic deficits, are likely contributing to the early impairment. 相似文献

Low informant agreement is of particular concern in clinical settings, since diagnoses and interventions are largely based on reports from parents and/or youths. This study explores youth-parent consistencies in an at-risk sample of youths (n = 42), several from immigrant and refugee families, all with stressful background experiences. Data from a community sample (n = 165) was used to contrast the clinical results. Results showed that correlations between clinical youths and parents were within the same range as those in the community sample. Consistencies concerning absolute level of behavior were higher in the clinical sample. However, interesting differences in informant consistencies were found on difficulties and resources between the two samples. This study adds to the picture that there is no simple relationship between severity of behavior deviance and informant agreement. Asking about behavioral resources as well as difficulties may provide valuable additional information regarding differences in the perspectives of at-risk youths and parents. 相似文献

Illusory line motion (ILM) has been shown to occur when a line is presented with one end next to a previously stimulated location. The line appears to be drawn away from the site of stimulation. It has been suggested that this is because of the allocation of attention to the stimulated site. Using an endogenous attentional manipulation (a central arrow cue) with no differences in the display between the two ends of the line at the time of line presentation or immediately prior, no ILM was detected, though there was a small effect in the opposite direction. Those who have found endogenously induced ILM have used an endogenous cue based on a property of a location marker that indicated the cued location. Changing the method of cuing to one based on a property of a peripheral marker instead of a central arrow produced a small but significant report of ILM. The small magnitude of the effect, participant self-reports, and the absence of the effect in the purely endogenous condition, suggest that this was merely a bias. ILM is not generated by endogenous attention shifts. 相似文献
