We explored response rate as a possible mediator of learned stimulus equivalence. Five pigeons were trained to discriminate
four clip art pictures presented during a 10-sec discrete-trial fixed interval (FI) schedule: two paired with a one-pellet
reinforcer, which supported a low rate of responding, and two paired with a nine-pellet reinforcer, which supported a high
rate of responding. After subjects associated one stimulus from each of these pairs with a discriminative choice response,
researchers presented two new clip art stimuli during a 10-sec FI: one trained with a differential reinforcement of low rate
schedule (DRL) after the FI and the other trained with a differential reinforcement of high rate schedule (DRH) after the
FI. Each of the stimuli that were withheld during choice training was later shown to see if the choice responses would transfer
to these stimuli. The results suggest that response rate alone does not mediate learned stimulus equivalence. 相似文献

Almost all 3‐ and 4‐year‐olds in Scotland now experience some form of pre‐school provision prior to school entry. Given such high rates of participation, the impact of pre‐school experiences on children's readiness for primary school has become an important issue for those involved in the early stages of compulsory schooling. Teachers in early years classes need to be aware of the experiences and achievements of individual children in their pre‐school setting to enable each child to transfer into mainstream education with the least amount of disruption to their learning. This study was carried out in one small Scottish local authority and explored the perceptions of early years teachers, from a diverse range of primary schools, of what information is important for them as children start school. This article presents the perspectives of Primary 1 teachers on children's readiness for schooling. It reports the factors, which these teachers identified as having an impact on successful transition from the pre‐school setting into the primary school. 相似文献

OBJECTIVE: Previous research has indicated that women who experience childhood physical abuse or childhood sexual abuse are at increased risk for posttraumatic stress disorder (PTSD) and adult victimization. Recently, peritraumatic dissociation (PD) has been suggested as another possible risk factor for PTSD and adult victimization. The purpose of the present study was to investigate the effects of childhood physical and sexual abuse and PD on PTSD and adult victimization. METHOD: A sample of 467 female college students completed questionnaires about childhood and adult sexual and physical abuse experiences, PD, and PTSD symptoms. RESULTS: The combined sexual and physical abuse (CA) and sexual abuse only (SA) groups reported significantly higher numbers of PTSD symptoms than the physical abuse only (PA) and no abuse (NA) groups. The CA and PA groups reported significantly more adult sexual and physical victimization than the SA and NA groups. Across all four groups, higher levels of PD were associated with higher levels of PTSD and adult sexual and physical victimization. CONCLUSIONS: The results of the current study suggest that different types of childhood abuse may lead to different adult problems. The results also indicated that PD may have a broad effect on PTSD development and adult victimization. 相似文献

This study aimed to assess the impact of pre-professional education on students' knowledge and attitudes about aging, including the option of a simulated learning activity. Using a mixed design, groups of nursing and nutrition students (n = 127) were randomly assigned to experience the Aging Game. Pre- and posttest observations included measures of anxiety, attitude and empathy. In the Aging Game, students played the role of an elderly adult with common physical disabilities during various scenarios and then reflected on the experience. As a result, students became more familiar with what being an older adult felt like, and increased understanding and empathy. 相似文献

In Experiment 1, two groups of female rats were trained in a triangular pool to find a hidden platform whose location was defined in terms of a single a landmark, a cylinder outside the pool. For one group, the landmark had only a single pattern (i.e., it looked the same when approached from any direction), while for the other, the landmark contained four different patterns (i.e., it looked different when approached from different directions). The first group learned to swim to the platform more rapidly than the second. Experiment 2 confirmed this difference when female rats were trained in a circular pool but found that male rats learned equally rapidly (and as rapidly as females trained with the single-pattern landmark) with both landmarks. This second finding was confirmed in Experiment 3. Finally, in Experiment 4a and 4b, male and female rats were trained either with the same, single-pattern landmark on all trials or with a different landmark each day. Males learned equally rapidly (and as rapidly as females trained with the unchanged landmark) whether the landmark changed or not. We conclude that male and female rats learn rather different things about the landmark that signals the location of the platform. 相似文献

ABSTRACTIn this paper, we draw on the ‘dilemma of difference’ to discuss the dangers and affordances of diagnosis within two of the most prevalent, yet under-supported, disabilities affecting school-age children: Attention Deficit Hyperactivity Disorder (ADHD) and Developmental Language Disorder (DLD). The dilemma that exists between denying and thereby ignoring difference on the one hand, versus recognising and potentially stigmatising difference on the other, will be explored and the consequences outlined. Our aim is to achieve a middle ground that conceives of diagnosis as a helpful starting point to enable educators to address barriers to access and participation through appropriate adjustments to curriculum, pedagogy and assessment. 相似文献
