A new schedule programming language is presented, including its implementation on a PDP-11 running under RSX-11M. This language combines modern syntax concepts of PASCAL with the state notation of SKED. The present implementation includes event-driven activation for fast response time and shared code for minimal storage requirements, allowing the simultaneous control of many experiments. 相似文献

This paper reviews psychophysical evidence for the existence and the nature of two types of anticipation in goal-oriented action. The first one relates to attained changes of the perceptual world, thus to action goals. These anticipations determine appropriate motor output. We argue that goal codes do not only serve as a reference unit, against which currently produced behavioral effects are compared. Rather voluntary actions appear to be planned literally in terms of intended behavioral effects. The second type of anticipation relates to the environmental conditions that have to be met to bring an intended effect into being. These anticipations serve to trigger selected actions, when appropriate execution conditions are encountered. Altogether, the behavioral evidence portrays a remarkable automaticity of goal-oriented action. Once a goal exists (wherever it might come from), corresponding efferent output is generated and executed under appropriate conditions. 相似文献

This study evaluates the horse (Equus caballus) use of human local enhancement cues and reaction to human attention when making feeding decisions. The superior performance
of dogs in observing human states of attention suggests this ability evolved with domestication. However, some species show
an improved ability to read human cues through socialization and training. We observed 60 horses approach a bucket with feed
in a three-way object-choice task when confronted with (a) an unfamiliar or (b) a familiar person in 4 different situations:
(1) squatting behind the bucket, facing the horse (2) standing behind the bucket, facing the horse (3) standing behind the
bucket in a back-turned position, gazing away from the horse and (4) standing a few meters from the bucket in a distant, back-turned
position, again gazing away from the horse. Additionally, postures 1 and 2 were tested both with the person looking permanently
at the horse and with the person alternating their gaze between the horse and the bucket. When the person remained behind
the correct bucket, it was chosen significantly above chance. However, when the test person was turned and distant from the
buckets, the horses’ performance deteriorated. In the turned person situations, the horses approached a familiar person and
walked towards their focus of attention significantly more often than with an unfamiliar person. Additionally, in the squatting
and standing person situations, some horses approached the person before approaching the correct bucket. This happened more
with a familiar person. We therefore conclude that horses can use humans as a local enhancement cue independently of their
body posture or gaze consistency when the persons remain close to the food source and that horses seem to orientate on the
attention of familiar more than of unfamiliar persons. We suggest that socialization and training improve the ability of horses
to read human cues. 相似文献

This study examined the role of motivation as a mediator of the relationship between parents' socio‐economic status (SES) and children's standardized test achievement in math. We employed a one‐year longitudinal approach using Programme for International Student Assessment (PISA) 2003 and a follow‐up exam in 2004. The sample consisted of N = 6020 German students (mean age 15.5 years, SD = .55) who continued school after Grade 9 (PISA 2003) and were in Grade 10 at the time of PISA 2004. Children completed measures related to their parents' SES, math‐specific self‐concept, task‐specific and global self‐efficacy, and interest, intelligence and mathematical competence. We found a small to moderate correlation between parents' SES and children's achievement. All motivational constructs partially mediated the relationship between father's SES as well as a family index for SES (economic, social, and cultural status) and children's mathematical competence, but only math‐specific self‐concept and self‐efficacy were significant mediators for mother's SES. Even when simultaneously considering the mediating effect of children's intelligence and prior achievement, the mediation effects of motivation remained significant. These results are important for our understanding of educational equality. Copyright © 2016 European Association of Personality Psychology 相似文献

The present study investigated whether effects of implicit learning (IL) are due to well-learned and explicitly represented parts of the stimulus material ("chunks"). To this purpose, event-related brain potentials (ERPs) were recorded during an oddball-version of a serial reaction time (RT) task: At unpredictable positions within a 16-item letter sequence, single deviant items replaced an item of the repeatedly presented standard sequence. After acquisition, the "process dissociation procedure" (Jacoby, 1991) was adopted to identify explicitly learned sequence parts for each participant. Acquisition of sequence knowledge was reflected in faster RTs for standard items than for deviant items and in enhanced N2b and P3b components for deviant items. While the ERP effects were obtained for explicitly represented sequence parts only, RT effects were independent of subsequent reproduction performance. These results indicated that (1) ERPs are a valid measure of explicit knowledge, (2) implicit and explicit knowledge coexist in serial RT tasks, and (3) chunking processes play a major role in the acquisition of explicit knowledge about event sequences. 相似文献

In adults, the selection and the planning of actions are influenced by the anticipation of desired action effects. However, the role of action effects for action control in infants is still an unresolved issue. One important prerequisite for infants action control is that infants are able to relate certain movements to certain effects. To test this assumption, it was investigated how infants action control is affected by action effects. By applying an imitation paradigm, we studied 12- and 18-month-old infants who first observed an adult experimenter demonstrating a three-step action sequence on a toy bear. In three experimental groups, the second action step, the third action step, or no action step elicited an arbitrary sound as an additional acoustic action effect. It was coded how often each of the target actions was performed by the infant in a subsequent 90-s test phase. As predicted, the frequency of the infants target action varied depending on which action step elicited the action effect. In both age groups, the target action that was combined with an acoustical effect was not only produced more often but also occurred with lower latency and was in most cases the first target action shown by the infants. These results are interpreted as evidence of the important role of action effects in infants action control. 相似文献

Two experiments compared the perception of apparent movement when the second of two successive stimuli always appeared in the same position and when it varied randomly between two spatial positions. The results of both experiments showed that foreknowledge of the position of the second stimulus does not facilitate the perception of apparent movement. Experiment 2 also clearly showed that the space-time relationships of Korte’s third law of apparent movement does not depend on foreknowledge of the position of the second stimulus. These findings imply that apparent movement in real time occurs after the second stimulus has been registered by the visual system. It suggests that apparent movement involves a delayed decision mechanism that stores the first stimulus, the interstimulus temporal interval, and the second stimulus, and then impletes a motion compatible with the stimulus information. 相似文献

The relationship between client-perceived rapport (as measured from a standardized client) and physical mirroring and the standard counsellor posture was investigated with interviews performed by 59 post-graduate students in counselling psychology. Videotaped recordings were used to code counsellor posture in the categories of: total postural mirroring, mirroring of the hands and arms, mirroring of the legs, mirroring of the torso, and the frequency of the standard counsellor posture across each minute of the interviews. These minutes were classified as 'high' in rapport or 'low' in rapport as measured by the standardized client. Results indicated that there was significantly more postural mirroring of the torso during high versus low minutes, but that the counsellor standard posture occurred significantly more frequently during low rapport minutes than in high rapport minutes. However, when examined over the entire length of the interviews, these data were able to be understood in terms of counsellor 'flexibility' of response rather than simply whether these postural behaviours were present or not. Implications for counsellor training are discussed. 相似文献
