We examined correspondence between preference assessment outcome and within‐session patterns of responding in one subject with autism. Responding maintained by a single highly preferred item resulted in a greater total number of responses, a slower decline in within‐session response rates, and a greater proportion of short interresponse times compared to responding maintained by varied moderately preferred (MP) stimuli. Presenting varied MP stimuli within the same session produced greater levels and more sustained responding than presenting those same stimuli individually. 相似文献

Increasing evidence suggests that common mechanisms underlie the direction of attention in physical space and numerical space, along the mental number line. The small leftward bias (pseudoneglect) found on paper-and-pencil line bisection is also observed when participants 'bisect' number pairs, estimating (without calculating) the number midway between two others. Here we investigated the effect of stimulus motion on attention in numerical space. A two-frame apparent motion paradigm manipulating stimulus size was used to produce the impression that pairs of numbers were approaching (size increase from first to second frame), receding (size decrease), or not moving (no size change). The magnitude of pseudoneglect increased for approaching numbers, even when the final stimulus size was held constant. This result is consistent with previous findings that pseudoneglect in numerical space (as in physical space) increases as stimuli are brought closer to the participant. It also suggests that the perception of stimulus motion modulates attention over the mental number line and provides further support for a connection between the neural representations of physical space and number. 相似文献

The relative efficacy of positive task interdependence, positive resource interdependence, and individualistic learning were compared with achievement and academic and personal social support. The authors randomly assigned to conditions 66 7th-grade Italian students with no previous experience in cooperative learning. They participated in 6 90-min instructional sessions dealing with the dangers of smoking, alcohol, and drugs. The results indicated that students assigned to the task-interdependence and resource-interdependence conditions achieved higher and perceived greater peer academic support than did students working individually. Students in the resource-interdependence condition showed a higher perception of peer personal support than students assigned to the other conditions. 相似文献

University of Colorado (CU) students were tested on memory for the “CU Fight Song” in order to examine serial position effects
in semantic memory while controlling for familiarity across positions. In Experiment 1, students reconstructed the order of the nine lines of the song. Students with previous exposure to the song performed better
and showed a more bowed serial position function than did students with no knowledge of the song. Experiment 2 added a task assessing memory of item information. One word was removed and replaced with a blank in each line, and an alternative
word was offered as an option, along with the correct word. Students selected the word that fit into each blank and then reconstructed
the order of the lines. There was a bow-shaped curve for order reconstruction, but not for item selection, which implies that
the serial position function in semantic memory stems from order, rather than item, information. 相似文献

This study examines factors that influence memory for details about people. In two experiments, subjects learned fictitious
details about familiar (friends, relatives) and/or unfamiliar individuals, and were tested both immediately and after a 1-week
delay. To control for a confounding between familiarity and genetic relatedness in Experiment 1, in Experiment 2 specific relationships (identical twin, first cousin, acquaintance) were assigned to unfamiliar individuals. Across experiments,
retention was enhanced for familiar compared to unfamiliar individuals, for friends/acquaintances compared to relatives, for
more closely than distantly related individuals, and for individuals of the opposite gender as the subject. 相似文献

Teacher expectancy effects, the class of phenomena in which teacher beliefs about students influence student outcomes, are widely believed to operate through recursive processes of teacher-student interaction. Recent work in “wise” interventions has shown profound and robust effects in educational domains, and has attributed these effects to similar recursive processes (Yeager and Walton 2011). In this paper, we lay a foundation for forging connections between what we know about expectancy effects and how we might envision applying that knowledge as a lever in intervention research. We review the evidence for the existence and significance of teacher expectancy effects, as well as their possible mediators, including perceptual biases, confirmation biases, stereotyping, and attributional biases. We also hypothesize that empathy could play a role in mediating a relationship between expectancies and attributions. Finally, we propose a research agenda focused on the transmission, mediation, and attributional effects of teacher expectancies. 相似文献

Attention is biased towards threat-related stimuli. In three experiments, we investigated the mechanisms, processes, and time course of this processing bias. An emotional flanker task simultaneously presented affective or neutral pictures from the international affective picture system database either as central response-relevant stimuli or surrounding response-uninformative flankers. Participants’ response times to central stimuli was measured. The attentional bias was observed when stimuli were presented either for 1500?ms (Experiment 1) or 500?ms (Experiment 2). The threat-related attentional bias held regardless of the stimuli competing for attention even when presentation time was further reduced to 200?ms (Experiment 3). The results indicate that automatic and controlled mechanisms may interact to modulate the orientation of attention to threat. The data presented here shed new light on the mechanisms, processes, and time course of this long investigated by still largely unknown processing bias. 相似文献
