And Task

10 odors were presented to three different groups of 20 subjects each (10 men and 10 women) to investigate the relationships among encoding conditions and both immediate and delayed incidental recognition of odors. Subjects who were not told to memorize the material and not informed of the final recognition test had to evaluate the intensity of each odor (Task 1), to judge the similarity of each odor to mint (Task 2), or to score each odor for pleasantness and sourness (Task 3). The subjects had to recognize test odors, represented one at a time, together with some distractors, immediately thereafter (Immediate Test) and one week later (Delayed Test). Task 1 and Task 2 produced better performances (77% and 75% of items recognized immediately; 66% and 69% recognized after a week) than Task 1. The performance on Task 3, more conceptually driven, was the worst, both immediately (67%) and a week later (52%). Sex and task reliably interacted: women performed better than men on Tasks 1 and 3, men on Task 2. Accuracy did not vary by task but by test time (immediate or delayed). Better performance on Tasks 1 and 2 may depend not only on more effective storage but also on the better fit between the task and the test.

And Task

A simple (one-channel) or a complex (three-channel) vigilance task was administered with or without threat of shock to a large group of flight students. It was found that a larger absolute decrement was obtained in the complex task, but the relative decrements were equivalent for both. One-channel monitoring was better overall than three-channel monitoring in the non-stressed condition. Stressed subjects performed better than nonstressed, and this enhancement was greater for three-channel monitoring.

Hypertext systems parse documents into components connected by machine-supported links. This study investigated several usability issues relating to linking configurations in an information retrieval application. A HyperCardTM-based geography data base was used as the information domain. Linear, hierarchical, network, and combination hierarchical/network linking were of particular interest. In addition, the number of required links (two, four, or six links to reach the answer) and task type were the task variables studied. Task type refers to expert programmers' judgments as to whether a task is best suited to a hierarchical or network linking configuration. The intention was to identify the task situations under which each linking structure excels. Results indicated that users of the hierarchical linking structure performed significantly better than those using network linking (on average requiring 49 s less per task). Subjects using the combination condition performed no worse than those using the hierarchical condition, yet the combination condition provided no consistent advantages. Hence, for novice users of a system, no performance gain results from the inclusion of network links (in isolation or in combination with hierarchical).

Test task scheduling problem (TTSP) is a typical combinational optimization scheduling problem. This paper proposes a variable neighborhood MOEA/D (VNM) to solve the multiobjective TTSP. Two minimization objectives, the maximal completion time (makespan) and the mean workload, are considered together. In order to make solutions obtained more close to the real Pareto Front, variable neighborhood strategy is adopted. Variable neighborhood approach is proposed to render the crossover span reasonable. Additionally, because the search space of the TTSP is so large that many duplicate solutions and local optima will exist, the Starting Mutation is applied to prevent solutions from becoming trapped in local optima. It is proved that the solutions got by VNM can converge to the global optimum by using Markov Chain and Transition Matrix, respectively. The experiments of comparisons of VNM, MOEA/D, and CNSGA (chaotic nondominated sorting genetic algorithm) indicate that VNM performs better than the MOEA/D and the CNSGA in solving the TTSP. The results demonstrate that proposed algorithm VNM is an efficient approach to solve the multiobjective TTSP.

This study investigated differences in the self-choice elaboration and an experimenter-provided elaboration on incidental memory of 7- to 12-yr.-olds. In a self-choice elaboration condition 34 second and 25 sixth graders were asked to choose one of the two sentence frames into which each target could fit more congruously, whereas in an experimenter-provided elaboration they were asked to judge the congruity of each target to each frame. In free recall, sixth graders recalled targets in bizarre sentence frames better than second graders for self-choice elaboration condition. An age difference was not found for the experimenter-provided elaboration. In cued recall self-choice elaboration led to better performance of sixth graders for recalling targets than an experimenter-provided elaboration in both bizarre and common sentence frames. However, the different types of elaboration did not alter the recall of second graders. These results were interpreted as showing that the effectiveness of a self-choice elaboration depends on the subjects' age and the type of sentence.

Individuals learn differently through trial and error, with some more influenced by good outcomes, and others weighting bad outcomes more heavily. Such valence biases may also influence memory for past experiences. Here, we examined whether valence asymmetries in reinforcement learning change across adolescence, and whether individual learning asymmetries bias the content of subsequent memory. Participants ages 8-27 learned the values of “point machines”, after which their memory for trial-unique images presented with choice outcomes was assessed. Relative to children and adults, adolescents overweighted worse-than-expected outcomes during learning. Individuals’ valence biases modulated incidental memory, such that those who prioritized worse- (or better-) than-expected outcomes during learning were also more likely to remember images paired with these outcomes, an effect reproduced in an independent dataset. Collectively, these results highlight age-related changes in the computation of subjective value, and demonstrate that a valence-asymmetric valuation process influences how information is prioritized in episodic memory.

The circumstances under which the shapes of figure-versus-ground regions are perceived and remembered were investigated in three experiments that replicate, extend, and clarify Rubin's [1921 Visuell wahrgenommene Figuren (Copenhagen: Gyldendals)] classic study on this topic. In experiment 1, observers reported which of two regions they perceived as figure within ambiguous, bipartite, 2-D displays. In a later shape-recognition test, the shapes of regions previously seen as figures were remembered well, but the shapes of regions previously seen as grounds were remembered no better than novel distractor regions. In experiment 2 we examined the same question about memory for the shape of figure-versus-ground regions in nested displays in which the central region could be perceived either as a closer figure surrounded by a farther ground (ie as a solid object) or as a farther ground surrounded by a closer figure (ie as an empty hole). Unlike experiment 1, the shapes of regions initially perceived as grounds (holes) were remembered as well as those of regions initially perceived as figures (solid objects), and much better than those of novel distractor regions. In experiment 3 we further demonstrated that this outcome did not depend on the figure – ground instructions employed in experiment 2, because the same result was obtained with unambiguous 3-D cardboard displays of objects versus holes with no figure – ground instructions at all. The present findings support an account of hole perception in which the shape of an intrinsic hole is encoded as a shaped, immaterial (or virtual) surface where the absence of matter is coded by a functional ‘missing’ symbol (analogous to a minus sign in mathematics) to represent its non-material status.

This study investigated the effects of text modification and task on incidental learning of foreign language vocabulary by reading. The focus of the study was on how different cue types (appositives and single and multiple-choice marginal glosses) and a task (translation) would affect processing of input, initial learning, and retention of the meaning of target words in a text. Two hundred thirty-one students in Japanese universities were randomly assigned to 10 condition groups. After a pretest, a reading task, and a cloze test, they were given a surprise vocabulary test. A week later, two unexpected delayed posttests were also given. The results indicated that (a) both single and multiple-choice marginal gloss conditions performed significantly better than the no cue and the appositive conditions, (b) no statistically significant difference existed between the single and the multiple-choice gloss conditions nor between the appositive and the no cue conditions, and (c) the translation task had no effect.

Background: Eating habits that are currently owned by elementary school age children are difficult to eat with amoung should be three times a day according to the needs, one of them is breakfast. When they didn’t breakfast before went to school they will deficiency  of intake. Energy that can cause the children quickly experience fatigue and less to concentration for accepting the lesson in the school. Psycomotor test reaction time is the interval between receiving stimulus with a respon do main which includes movement behaviour and physical coordination, motor skills.Objectives: The purpose of this research is to analyze test time reaction psychomotor and to provides an overview of thetime difference reaction between students who breakfast and did not have breakfastMethods: This study is an observational study using cross sectional design. The sample in this study was school children aged 9-12 years  much as 100 children by measuring the reaction time of students who had breakfast or not breakfast with a special tool called Body ReactionResults: The result showed that of 45 % students have a habit of breakfast and at 55 % students do not have a habit of breakfast with psychomotor test time reaction between students who breakfast is better than the students who did not breakfast( p-value 0.01<0.05 ).Conclusions: There is the differencein psychomotor test time reaction between students who breakfast and did not have breakfast.Explained that the students also took a chance breakfast first before he left school, because with breakfast will be triggered growth and maximize the capability of at school.ABSTRAKLatar Belakang: Kebiasaan makan yang saat ini dimiliki oleh anak usia sekolah dasar adalah sulitnya untuk makan dengan jumlah yang seharusnya yaitu 3 kali dalam sehari sesuai dengan kebutuhan, salah satunya adalah sarapan. Disaat mereka tidak sarapan sebelum berangkat ke sekolah mereka akan kekurangan asupan energi yang dapat menyebabkan anak tersebut cepat mengalami kelelahan dan kurang konsentrasi dalam menerima pelajaran saat di sekolah. Uji psikomotor waktu reaksi adalah interval antara penerimaan stimulus dengan suatu responyang meliputi perilaku gerakan dan koordinasi jasmani, ketrampilan motorik dan kemampuan fisik seseorang.Tujuan: Untuk menganalisis hasil uji psikomotor waktu reaksi serta untuk memberikan gambaran mengenai perbedaan waktu reaksi antara siswa yang sarapan dan tidak sarapanMetode: Penelitian ini merupakan penelitian yang bersifat observasional dengan menggunakan design cross sectional. Sampel dalam penelitian ini adalah anak sekolah usia 9-12 tahun yaitu sebanyak 100 anak dengan cara mengukur waktu reaksi siswa baik yang sudah sarapan atau tidak sarapan dengan alat khusus yaitu Body ReactionHasil: Hasil penelitian menunjukkan bahwa sebesar 45% siswa memiliki kebiasaan sarapan dan sebesar 55% siswa tidak memiliki kebiasaan sarapan dengan hasil uji psikomotor waktu reaksi antara siswa yang sarapan lebih baik dibandingkan dengan siswa yang tidak sarapan (p-value 0,01<0,05).Kesimpulan: Terdapat perbedaan uji psikomotor waktu reaksi antara siswa yang sarapan dan tidak sarapan. Sebaiknya siswa menyempatkan sarapan terlebih dahulu sebelum berangkat sekolah, karena dengan sarapan akan memacu pertumbuhan dan memaksimalkan kemampuan di sekolah.

Hearing Impaired Children

Ten spondaic words recorded on Language Master cards were presented monaurally, through insert receivers, to 58 hearing-impaired children to evaluate their ability to recognize familiar speech material. The subjects ranged in age from five to nine years, and their average pure-tone thresholds (500-1000-2000 Hz) ranged in hearing level from 52 to 123 dB (ANSI, 1969). The children were tested individually, on consecutive days, until their performance stabilized—which required from four to 10 sessions. They indicated their responses by pointing to labeled picture cards. Spondee recognition scores were bimodally distributed, with clusters of scores of 0–65% and 66–100%, respectively. In general, pure-tone averages better than 93 dB HTL were associated with spondee scores from 66 to 100%, while pure-tone averages poorer than 103 dB HTL corresponded to spondee scores from 0 to 65%. However, no close relation between pure-tone thresholds and spondee recognition scores was found for average hearing levels between 93 and 103 dB. Recognition scores varied as a function of repeated testing in three general ways: stable performance, steadily improving performance, or inconsistent performance.
