Using geometry to specify location: implications for spatial coding in children and nonhuman animals
The study of spatial cognition has benefited greatly from a technique known as the disorientation procedure. This procedure
was originally used with rats to show that they relied on the geometry of an enclosed space to locate a target hidden in that
space. Disorientation has since been used with a variety of mobile animals, including human children, to examine the coding
of geometric information. Here, we focus mostly on our recent work with young children. We examine a set of issues concerning
reorientation—namely, the nature of geometric coding, the processes invoked by disorientation, and the developmental origins
of using geometric information to determine location. We have employed a variety of methods to examine these issues; the methods
include analyzing search behaviors, using spaces of different shapes, varying viewing position, and comparing different disorientation
procedures. The implications for how children and nonhuman animals code geometric information are discussed. 相似文献

Forensic interviewing involves gathering information from a suspect or eyewitness. Administering a model statement during an interview results in greater information elicitation, which can enhance lie detection. Typically, a model statement is a highly detailed statement, on an unrelated topic to that of the interview. This study examined the effect of manipulating the modality of the MS, either by allowing participants to listen to (Audio‐MS), or read (Written‐MS) a model statement. A total of 162 (81 truth tellers, 81 liars) participants were randomly allocated to one of three interviewing conditions where they received either the Audio‐MS, Written‐MS, or No‐MS (control condition). Truth tellers honestly reported a “spy” mission, whereas liars performed a covert mission and lied about their activities. Results showed both model statements were equally more effective at eliciting information and facilitating lie detection, compared with a control condition. Theoretical and practical implications are discussed. 相似文献

We start from Marra–Spada duality between semisimple MV-algebras and Tychonoff spaces, and we consider the particular cases when the \(\omega \)-skeleta of the MV-algebras are restricted in some way. In particular we consider antiskeletal MV-algebras, that is, the ones whose \(\omega \)-skeleton is trivial. 相似文献

Groove is often described as a musical quality that can induce movement in a listener. This study examines the effects of listening to groove music on corticospinal excitability. Musicians and non-musicians listened to high-groove music, low-groove music, and spectrally matched noise, while receiving single-pulse transcranial magnetic stimulation (TMS) over the primary motor cortex either on-beat or off-beat. We examined changes in the amplitude of the motor-evoked potentials (MEPs), recorded from hand and arm muscles, as an index of activity within the motor system. Musicians and non-musicians rated groove similarly. MEP results showed that high-groove music modulated corticospinal excitability, whereas no difference occurred between low-groove music and noise. More specifically, musicians’ MEPs were larger with high-groove than low-groove music, and this effect was especially pronounced for on-beat compared to off-beat pulses. These results indicate that high-groove music increasingly engages the motor system, and the temporal modulation of corticospinal excitability with the beat could stem from tight auditory–motor links in musicians. Conversely, non-musicians’ MEPs were smaller for high-groove than low-groove music, and there was no effect of on- versus off-beat pulses, potentially stemming from suppression of overt movement. In sum, high-groove music engages the motor system, and previous training modulates how listening to music with a strong groove activates the motor system. 相似文献

The influence of dopaminergic replacement (DR) on gait in people with Parkinson's disease (PD) is well documented. However, little is known about the acute effects of dopamine on more complex locomotor tasks that require visual guidance to avoid obstacles during gait. The authors investigated the influence of DR on locomotor behavior in a task where movement planning and control might be challenged by the height of the obstacle. The PD group included patients diagnosed with idiopathic PD (n = 12), as well as healthy controls (n = 12). Patients walked and stepped over obstacles of different heights before (OFF) and after (ON) levodopa intake. Spatial adjustments were not modulated by DR, but the step time to perform these anticipatory gait adjustments was longer only in PD-OFF (compared with healthy controls) when approaching the highest obstacle, but not PD-ON. During the crossing phase, trail limb toe clearance of PD patients was shorter than healthy controls only during the OFF state. ON-OFF comparisons were significantly different only for the time to reach the lead foot clearance over the highest obstacle. In summary, DR partially improved movement slowness but did not directly affect movement amplitude of lower limb regulation in this gait task. 相似文献

The new edition of the DSM is proposing significant changes to current diagnostic definitions of autism and related conditions. In this article, we will discuss the clinical, research, and cultural implications of these changes. We conclude that the new criteria appear to better reflect current understanding of the autism spectrum disorder than the current DSM‐IV criteria. As expected with any major change in classification systems, there are also significant risks, which will have to be carefully monitored and addressed by both policy makers and the scientific community to ensure that best clinical practice and research are facilitated and advanced. 相似文献

In this article, I trace the shifting theorisation of religious conflict to argue that religious conflict in the USA is shaped by a dialectic of religious and secular movements. Church-sect theory, which was originally a class-based theoretical framework, was appropriated by the rational choice approach in the sociology of religion, which instead privileged competition in a religious marketplace. Ernst Troeltsch described divisions between church and sect, but H. Richard Niebuhr demarcated a denominational divide in the USA based on class, region, ethnicity and race. In the 1980s, Wade Clark Roof and William McKinney, Robert Wuthnow and James Davison Hunter observed that the differences in the US were no longer necessarily between denominations but could occur within denominations. For them, what had become known as the Culture Wars were based on a conflict between religious liberals/progressives and religious conservatives/orthodox. This conflict is shaped by a dialectic of secular and religious movements and counter-movements. 相似文献

We test whether comparison can promote learning of new relational abstractions. In Experiment 1, preschoolers heard labels for novel spatial patterns and were asked to extend the label to one of two alternatives: one sharing an object with the standard or one having the same relational pattern as the standard. Children strongly preferred the object match when given one standard but were significantly more likely to choose the relational match when they compared two standards. Experiment 2 provided evidence that comparison processing—as opposed to simply seeing two exemplars—is necessary for this relational effect. Preschoolers who were shown the two standards sequentially without a prompt to compare them preferred object matches, as did those who viewed only one standard. In contrast, those who saw the exemplars together, with a prompt to compare them, showed the same elevated relational responding as found in Experiment 1. We suggest that structural alignment processes are crucial to developing new relational abstractions. 相似文献

Abstract The cognitive model of social anxiety disorder (SAD) assumes that cognitive biases are important maintaining factors of the disorder. Research and theory have highlighted the impact of cognitive self-regulatory processes on affect, but have not sufficiently focused on the influence of affect on self-regulatory cognitions. The present study examined the influence of affect on cognitive self-regulatory mechanisms in SAD by focusing on one critical cognitive bias, estimated social cost. Individuals with SAD (N=48) and non-anxious controls (N=48) were randomly assigned to one of three experimental, affect induction conditions (negative, positive, or neutral) before giving a 10-minute impromptu, videotaped speech. As expected, the affect manipulation resulted in changes in estimated social cost. However, this effect was not specific to individuals with SAD. Participants in the positive affect condition in both groups had the highest social cost estimates post-speech challenge. These results suggest that social cost bias is dependent on the affective state in both individuals with SAD and controls. 相似文献
