An investigation of expertise in cycling: Eye tracking,Think Aloud and the influence of a competitor

ObjectivesTwo studies investigated expert-novice differences in information-seeking behaviour, cognitions and performance during cycling time trials (TT). Study 1 examined trained and novice cyclist’s cognitions whilst performing a TT, using a Think Aloud (TA) protocol and eye-tracking techniques. Study 2 investigated expertise differences during alone and competitive TTs.Methodsin Study 1, six trained and seven novice cyclists performed a 16.1 km TT. In Study 2, eight trained and ten novice cyclists performed three 16.1 km TT; a baseline TT, an alone TT and a trial against a virtual competitor. In both studies, participants were asked to TA and in Study 1 they also wore mobile gaze-tracking glasses. Performance feedback and a simulated TT course were visually displayed during all trials, as was a virtual avatar during the competitor trial. Verbalisations were coded into primary and secondary themes. Cognitions and pacing strategies were compared between groups and across the duration of the TTs. In Study 1, eye-tracking data for total dwell time and gaze frequency were calculated for each area of interest (Time Elapsed, Power, Heart Rate, Cadence, Distance Covered, Speed and Course Scenery).ResultsIn Study 1, no significant differences were found in information-seeking behaviour between groups, however there were expertise differences in the cognitive strategies used. Trained cyclists’ verbalisations were more performance-relevant (i.e., power output), whereas the untrained group were more focused on task completion (i.e., distance and time) and irrelevant information. Both groups talked more about distance and motivational thoughts in the later stages of the trial, and dwell time on distance feedback also increased in this final 4 km. In Study 2, the trained group performed faster than the untrained group but there were no significant differences in pace or performance between alone and competitive TTs for either group. Differences in cognitions were found between groups and across the TT duration.ConclusionBoth studies demonstrate that cognitive processes differ as a function of expertise during self-paced cycling time trials. There were no differences in information-seeking behaviour between trained and untrained cyclists and there was no effect of an opponent on pace or performance.     

Feedback in Couple and Family Therapy: A Randomized Clinical Trial

Routine Outcome Monitoring (ROM) is recommended as a psychotherapy procedure to serve as clinical feedback in order to improve client treatment outcomes. ROM can work as a warning signal to the therapist if the client shows signs of no change or deterioration. This study has investigated whether any difference in outcome could be detected between those clients in couple and family therapy who used the Systemic Therapy Inventory of Change (STIC) feedback system (ROM condition) versus those who were offered treatment without the use of STIC (“treatment as usual” or TAU condition). A sample of 328 adults seeking couple and family therapy in Norway was randomly assigned to ROM versus TAU conditions. Outcome measures were The Outcome Questionnaire–45 and The Revised Dyadic Adjustment Scale. The results demonstrated no significant differences in outcomes between the ROM and TAU. Possible explanations of this result related to design and implementation issues are discussed.     

论《易经》作者的主体意识与道德内求思想

《易经》作者具有强烈的主体意识和道德内求思想,这典型地表现在《谦》、《节》、《中孚》、《遁》等集中论述道德修养的专卦之中,亦散见于《乾》、《履》、《同人》、《恒》、《随》、《升》、《萃》、《既济》诸卦之中。《易经》作者之所以对主体意识和道德内求思想给予了极大的关注,是因为在生产力极不发达的古代社会中,主体意识和道德伦理对于古老社会共同体内各种关系的协调和稳定,对于人类改造客观世界活动的成功,具有至关重要的作用。     

动机与情境对不同自控水平儿童学业求助的影响

本实验以小学儿童为被试,研究了在不同动机取向和情境条件下的不同自我控制水平儿童的学业求助行为。结果表明：（１）单独无自尊压力的解难题情境比群体压力情境导致更多的求助行为。（２）低自控儿童比高自控儿童产生更多的执行性求助,但主要表现在单独无自尊压力的情境下。（３）在群体压力情境下,自我卷入的儿童比任务卷入的儿童表现出更多的求助行为。（４）在单独无自尊压力的情境下,任务卷入的儿童比自我卷入的儿童表现出     

Negative-Feedback Seeking Leads to Depressive Symptom Increases Under Conditions of Stress

An earlier empirical investigation found the interaction of negative-feedback seeking and roommate rejection to be predictive of increases in depressive symptoms. This study replicated and elaborated this finding. Participants who sought negative feedback and performed below their personal standard of success were more likely to experience a subsequent increase in depressive symptoms compared with all other students. Furthermore, the interaction of negative-feedback seeking and midterm failure was specific to predicting increases indepressive symptoms, and did not predict anxious symptoms, thus supporting the specificity of the model to depression. These findings suggest that negative-feedback seeking, combined with a negative life event, may place an individual at increased risk for depressive symptoms. Potential methods and consequences of disrupting the pattern of negative-feedback seeking are discussed.     

二级强化程序在药物成瘾研究中的应用

二级强化程序是一种以物质的强化效应为基础,评价药物的精神依赖性潜力的方法,将其应用到自身给药实验中,即为二级强化自身给药模型。在这个模型中,动物在条件性刺激的影响下按压杠杆以寻求药物的行为反映了其对成瘾性药物的渴求。使用二级强化程序,人们发现：条件性刺激既能够影响觅药行为的获得和保持,也能够影响这种行为的消退;伏隔核的核区、杏仁核基底外侧部和内侧前额皮层等部位在药物相关的条件性刺激诱导动物产生觅药行为的过程中起重要作用。二级强化程序的应用为开发治疗药物成瘾的物质提供了一条新思路     

Experience and desire: A new format for Sensation Seeking Scales

A new form (VI) of the Sensation Seeking Scale (SSS) was developed which separates reports of past experiences from desired or intended future experiences on both Disinhibition (Dis) and Thrill and Adventure Seeking (TAS) factors. Factor analyses were used to select items for the scales. High internal reliabilities were found for the Experience-Dis, Intention-TAS, and Intention-Dis scales, but only moderate reliability was found for the Experience-TAS scale. Retest reliabilities were high for all scales. The Experience-TAS and -Dis scales were highly correlated for males but not for females. The Experience- and Intention-TAS scales were moderately correlated, and the Experience- and Intention-Dis scales were highly correlated for both sexes. Both the TAS and the Dis scales on form V were highly correlated with the corresponding Intention scales on form VI. Uses for the new SS scales in individual assessment are suggested.A copy of SSS form VI may be obtained from the author.     

A sensation seeking scale for children: Further refinement and psychometric development

A revision of the Sensation Seeking Scale for Children (SSSC) was standardized and validated on a community sample of 660 elementary- and middle-school children and 168 clinic-referred male children. Factor analysis of the combined samples yielded three unique factors, entitled Thrill and Adventure Seeking, Drug and Alcohol Attitudes, and Social Disinhibition. Psychometric indices of reliability and validity were acceptable, but test-retest reliability was only moderate. Differences in SSSC scores according to sex, ethnic group, age, and intellectual status were similar to those found previously with the adult Sensation Seeking Scales. Consistent with documented relations between adult antisocial personality and sensation seeking, the SSSC distinguished boys with conduct disorder (CD) from clinic controls, but the SSSC scores of boys with CD did not differ from those of the community sample boys. Discussion includes suggestions as to the continued study of the assessment of sensation seeking in children.This research was supported by National Institutes of Health Grant 1-R01-MH42529-04 and is based on the doctoral research of the first author.

利用重新修订非特指行业的雇主品牌量表,以求职倾向为因变量,通过两个有递进关系的研究,证实不仅雇主品牌结构的功能特征正向影响求职倾向,雇主品牌结构的象征特征与求职者追求的理想自我形象一致性也正向影响求职倾向,表明人们求职时既注重满足个人物质利益的雇主品牌功能特征,也关注求职企业雇主的特征风格与自我理想形象的契合。     

新颖寻求特质对药物成瘾易感性的影响及其机制

新颖寻求特质是个体对新颖刺激或潜在的奖赏线索表现出愉悦或兴奋的先天倾向, 并且这种先天倾向会导致个体为寻求潜在的奖赏进行频繁的探索性活动。众多研究表明, 新颖寻求水平高的个体药物成瘾易感性高。多巴胺、5-羟色胺、谷氨酸、γ-氨基丁酸、胆囊收缩素、成纤维细胞生长因子及皮质酮可能参与了新颖寻求特质影响药物成瘾易感性的过程。未来, 仍需对新颖寻求特质影响药物成瘾易感性的神经生物学机制进行深入研究。
