The Hartman and Hasher (1991) garden-path sentence completion task has been used in several studies to assess the efficiency of the deletion function of inhibition (e.g., L. Hasher, R. Zacks, & C. P. May, 1999 ), with results suggesting that younger adults are efficient at suppressing once relevant but no longer appropriate information, whereas older adults generally are not (e.g., M. Hartman & L. Hasher, 1991: L. Hasher. M. B. Quig, & C. P. May, 1997; C. P. May & L. Hasher, 1998). An alternative interpretation of patterns of access to relevant and no-longer-relevant sentence endings focuses on the difficulty of selecting final words for sentence frames and on integration effects in implicit memory (M. Hartman, 1995). This alternative is considered and found wanting on the basis of both new and old empirical data. On the basis of present data and related findings, it is concluded that the task does measure inhibitory efficiency. 相似文献

Evaluations are made of three computer-based driving systems presented at the 1993 Society for Computers in Psychology conference. These systems are compared and contrasted on the dimensions of realism, validity, cost, data-output, and application goals. All three systems have positive attributes on each of the five dimensions, but in different ways, yielding systems that complement each other in their usefulness for research, assessment, and advisement. We note that the systems have strong potential for applications with elderly drivers, but that all three systems need expansion for use with high-risk youthful drivers. 相似文献

This study was designed to examine the relevance of some cognitive skills to Chinese reading and to identify those that distinguish readers of different proficiency levels. Third-, fourth-, and fifth-grade children were given two sets of tests, the Chinese Reading Proficiency Test and five component skill tests. Skills in word recognition and in comprehension were examined through tasks measuring component detection, lexical coding, memory for gist, knowledge of syntax, and use of context. Subjects' responses on the knowledge of syntax task and the lexical coding task were found to be most effective in predicting reading proficiency of the third graders, but not the fourth- and fifth-grade children. Instead, use of context task was the best predictor of the older children's reading proficiency. 相似文献

Spatial reasoning, where novel spatial relationships are inferred based on trained relationships, can be conceptualized as arbitrarily applicable spatial relational responding. Here, we conducted two experiments to develop and validate, for the first time, a laboratory procedure to establish arbitrarily applicable spatial relational responding in adult humans. In Experiment 1, participants were trained on nonarbitrary spatial relational tasks designed to establish contextual cues for left of, right of, above, and below. Contextual cues were then used to train a series of arbitrary spatial relations involving four abstract shapes. Following training in a subset of arbitrary relations (A is left of B, B is above C, C is right of D), subsequent testing examined the emergence of untrained spatial relations (B is right of A, C is below B, D is left of C, D is below A and A is above D). When absent in initial tests, spatial relational responding was facilitated by a remedial training procedure incorporating nonarbitrary relational guidance. Participants showed patterns of spatial relational responding consistent with test relations. In Experiment 2, a variant reversal design yielded predictable, reversed spatial relational responses. Overall, the present procedures represent the first empirical demonstration of arbitrarily applicable spatial relational responding and thus, arguably, the first functional analytic model of spatial reasoning. 相似文献

This research investigated the influence of parental practices on helpless behaviors of struggling readers during homework tasks. Parents (N = 36) of elementary students reported on their children's helpless behaviors, such as task avoidance and negative affect, during homework assignments, and on the nature and frequency of their support. Distinctions were made between parental support considered to be strategic, compensatory, or intrusive. Additional variables that influence achievement behaviors were assessed, including children's language skills, academic abilities, and behavior regulation. Parent support considered intrusive, such as unsolicited interruptions and corrections, along with children's behavior regulation abilities, accounted for the greatest variation in struggling readers' helpless behaviors. 相似文献

Depression has been reported to be associated with a greater risk of death and cardiovascular disease (CVD); however, the impact of antidepressants (ADM) on CVD risk remains controversial. Statin use is known to decrease CVD risk. Whether the use of these medications together affects CVD risk has not been studied. Patients (N = 26,828) completing the patient health questionnaire (PHQ-9), ≥40 years of age, without prior CVD, and no prior ADM use were studied. Depressive severity was categorized as none-mild (PHQ-9 score ≤14, n = 21,517) and moderate-severe (PHQ-9 score ≥15, n = 5311). Cox hazard regression was used to evaluate the association of no ADM/no statin use (n = 23,104 [86.1%]), ADM/no statin use (n = 877 [3.3%]), no ADM/statin use (n = 2627 [9.8%]), and ADM/statin use (n = 220 [.8%]) with major adverse cardiovascular events (MACE: death, CAD, stroke). Patients averaged 56 ± 12 years; 61% female. There were 1182 (4.4%) 3 year MACE events. The association of ADM and statin use with MACE varied by depressive symptom severity, with statin therapy associated with a decreased risk in the none-mild group (HR = .78, p = .007) and ADM in the moderate-high group (HR = 0.58, p = 0.02). Concomitant use of ADMs and statins did not appear to provide additive benefit. 相似文献
