It has been proposed that spatial reference frames with which object locations are specified in memory are intrinsic to a to-be-remembered spatial layout (intrinsic reference theory). Although this theory has been supported by accumulating evidence, it has only been collected from paradigms in which the entire spatial layout was simultaneously visible to observers. The present study was designed to examine the generality of the theory by investigating whether the geometric structure of a spatial layout (bilateral symmetry) influences selection of spatial reference frames when object locations are sequentially learned through haptic exploration. In two experiments, participants learned the spatial layout solely by touch and performed judgments of relative direction among objects using their spatial memories. Results indicated that the geometric structure can provide a spatial cue for establishing reference frames as long as it is accentuated by explicit instructions (Experiment 1) or alignment with an egocentric orientation (Experiment 2). These results are entirely consistent with those from previous studies in which spatial information was encoded through simultaneous viewing of all object locations, suggesting that the intrinsic reference theory is not specific to a type of spatial memory acquired by the particular learning method but instead generalizes to spatial memories learned through a variety of encoding conditions. In particular, the present findings suggest that spatial memories that follow the intrinsic reference theory function equivalently regardless of the modality in which spatial information is encoded. 相似文献

Faith was defined as the search for an integrating center of value and meaning that is cognitional in nature, developmental in process, and transcendental in its dimensions. An original psychometric measure was constructed and tested in two samples in a midwestern metropolitan area. The life span sample of Catholics (N = 509) ranged in ages 18–84, median age 49. Respondents were 40% male, 60% female. The sample of college students (N = 303) had a mode age of 19, but was ethnically and religiously diverse. The results indicated that the covariance structure of the scale was equivalent for the two samples. The scale clearly measures 4 independent aspects of faith: Self and Moral development, God and Death, Ritual, and Authority. Reliability was established for four developmental Ways of Faith, based on Bernard Lonergan's intentionality analysis: Common Sense Faith, Thoughtful Faith, Responsible Faith, and Transcendent Faith. The data suggested that faith development may be best conceived as a continuous reworking of one's faith, rather than a sequence of acquisition and abandonment of beliefs. A mixed pattern of modest gender, age, and attachment effects was found for the Ways of Faith. A measure of self-church identification was found to be a consistent correlate of faith development. 相似文献

The present study investigated the role of object-centered reference systems in memories of objects' locations. Participants
committed to memory the locations and orientations of either 11 human avatars (Experiment 1) or 11 animal models (Experiment 2) displayed in a desktop virtual environment and then completed judgments of relative directions, in which they pointed to
objects from imagined vantage points corresponding to the locations of the objects. Results showed that, with avatars, performance
was better when the imagined heading was congruent with the facing direction of the avatar located at the imagined vantage
point. With animal models, no such facilitation was found. For both types of stimuli, performance was better for the learning
view than for the novel 135° view. Results demonstrate that memories of the locations of objects are affected by object-centered
reference systems and are consistent with conjectures that spatial memories are hierarchies of spatial reference systems,
with higher levels corresponding to larger scales of space. 相似文献

The influence of intentional and incidental learning on acquiring spatial knowledge during navigation 总被引:1,自引:0,他引:1
In order to study the influence of intentional and incidental learning conditions on route learning, young adults walked a route through a university building. Half of the participants focused their attention on the route (intentional learning condition), while the other half did not (incidental learning condition). Five tests of spatial knowledge were employed: a route-length-estimation, landmark recognition, landmark ordering, map-drawing and navigation task. The intentional group performed better than the incidental group on the map-drawing and navigation task. No difference between the intentional and incidental group was found on the landmark-recognition and landmark-ordering task. Moreover, the intentional group overestimated the walking distance, while the incidental group underestimated it. These results suggest that route knowledge (landmark recognition and landmark ordering) requires less effortful processing than survey knowledge (developing a map-like representation and actual navigation). 相似文献

In an exploration of Istomina's (1975) paradigm contrasting children's recall from an involuntary or game-like context with recall from an intentional or lesson-like context, this study investigated the relative efficacy of asking 4- and 5-year-olds "to remember" or "to play with" a set of 16 pictures or toys in a naturalistic or laboratory setting. The children's behavior and language were measured during two 2-min study phases, after which recall was assessed. Toys promoted different study phase activities and better retention than pictures, asking a child "to remember" a set of toys led to less recall than asking the child "to play" with the toys, and, across all conditions, instructions "to play" and "to remember" elicited differentiated study phase responses but similar levels of retention. 相似文献

In three experiments, we investigated whether the information available to visual perception prior to encoding the locations of objects in a path through proprioception would influence the reference direction from which the spatial memory was formed. Participants walked a path whose orientation was misaligned to the walls of the enclosing room and to the square sheet that covered the path prior to learning (Exp. 1) and, in addition, to the intrinsic structure of a layout studied visually prior to walking the path and to the orientation of stripes drawn on the floor (Exps. 2 and 3). Despite the availability of prior visual information, participants constructed spatial memories that were aligned with the canonical axes of the path, as opposed to the reference directions primed by visual experience. The results are discussed in the context of previous studies documenting transfer of reference frames within and across perceptual modalities. 相似文献

A meta-analysis is presented of the academic achievement effects on students taught by teachers from alternative teacher preparation (ATP) programs, compared to students taught by teachers from traditional teacher preparation (TTP) programs. The literature has indicated mixed results on the student-level academic outcomes of ATP programs. Findings from this meta-analysis indicate an overall statistically significant, yet small, difference in ATP and TTP programs (g?=?0.03; 95% CI?=?0.01, 0.04, p?=?0.001), with the mean achievement of students who had ATP teachers was about 0.03 standard deviations above that of students who had TTP teachers. Further, there were differences in student achievement by type of ATP program, school level, and academic subject area. These results, as well as implications for policy and practice are discussed. 相似文献

The incremental and all-or-none theories of verbal learning are compared by means of a little-used but methodologically superior variation of the “drop-out” paradigm with paired associates. Earlier experiments purporting to be relevant to the controversy are rejected as failing to offer a conclusive distinction between the two theories. The results presented here are taken to support the incremental theory. It is suggested that irregularities in the results of this and other experiments are caused by several intrusive factors, and a “dual-factor” hypothesis which was put forward to account for these irregularities is questioned on logical and methodological grounds. 相似文献

The goal of this study was to examine incidental and intentional spatial sequence learning during middle childhood and adolescence. We tested four age groups (8-10 years, 11-13 years, 14-17 years, and young adults [18+ years]) on a serial reaction time task and used manual and oculomotor measures to examine incidental sequence learning. Participants were also administered a trial block in which they were explicitly instructed to learn a sequence. Replicating our previous study with adults, oculomotor anticipations and response times showed learning effects similar to those in the manual modality. There were few age-related differences in the sequence learning indexes during incidental learning, but intentional learning yielded differences on all indexes. Results indicate that the search for regularities and the ability to learn a sequence rapidly under incidental conditions are mature by 8 to 10 years of age. In contrast, the ability to learn a sequence intentionally, which requires cognitive resources and strategies, continues to develop through adolescence. 相似文献

Rats homed with food in a large lighted arena. Without visual cues, they used dead reckoning. When a beacon indicated the home, rats could also use the beacon. Homing did not differ in 2 groups of rats, 1 provided with the beacon and 1 without it; tests without the beacon gave no evidence that beacon learning overshadowed dead reckoning (Experiment 1). When the beacon was at the home for 1 group and in random locations for another, there was again no evidence of cue competition (Experiment 2). Dead reckoning experience did not block acquisition of beacon homing (Experiment 3). Beacon learning and dead reckoning do not compete for predictive value but acquire information in parallel and are used hierarchically. 相似文献

A paradigm that required that subjects learn two responses to each of 10 schematic faces was used to study the relative rate of discrimination and generalization learning. One response uniquely identified each face, whereas the second response classified each face as a member of one of two categories. Rapid category learning and slow item learning suggested that category responses were learned on the basis of abstracted information, but item responses depended on the more difficult task of discriminating among patterns. The results are related to categorization models and to task variables that should influence the relative rates of discrimination and generalization learning. 相似文献

The interpretation of implications as rules motivates a different left-introduction schema for implication in the sequent
calculus, which is conceptually more basic than the implication-left schema proposed by Gentzen. Corresponding to results
obtained for systems with higher-level rules, it enjoys the subformula property and cut elimination in a weak form. 相似文献

Four, six, and ten-year-old children were required to copy an object's location and orientation within a two-dimensional spatial layout under two conditions: when both E's standard board and that of the S's were in the same orientation and when they were rotated 180 ° from each other. The failure of the 4-yr-olds to copy location and orientation under both conditions even when space was topographically coded indicates that at this age the child does not conceptualize space within two dimensions. Although the errors of the 4-yr-olds tended to be of a self-reference nature with respect to orientation and location on rotation trials the axes of the self-reference system were not coordinated. Six and 10-yr-old children performed significantly better on both conditions, with the exceptions that the 6-yr-olds continued to preserve some orientations within a self-reference system. When topographical codes were removed and S imagined rotation there were no significant age differences in total errors; however, older children organized entire subspaces within a self-reference system. The findings support Piaget and Inhelder's hypothesis that two-dimensional reference systems do not develop until the period of concrete operational thought, and they also indicate that even at age 10, the self-reference system continues to function when topographical codes are absent. Several cognitive mechanisms proposed to account for the development of spatial abilities are critically discussed. 相似文献
