In a study with 365 teacher students, 447 teacher trainees, and 123 teachers, the ability to detect students’ deception was
tested. Participants judged the credibility of videotaped students who were accused of academic dishonesty (having cheated
in a test). Half of these messages were actually true (students had not cheated on the test) and half of them were deceptive
(students had cheated on the test). As expected and in line with findings on the influence of expertise on the ability to
detect deception from other fields, we found that the overall accuracy rate of teachers was not higher than that of teacher
trainees and teacher students. Moreover, we found no effect of teaching experience (years working as a teacher) on overall
detection of deception accuracy. Interestingly, teachers were found to have a stronger truth bias and therefore had a lower
accuracy in detecting deceptive messages than teacher students and teacher trainees (veracity effect). While teacher characteristics
accounted for very little variance, senders’ opportunity to prepare and their gender had strong effects. Detection accuracy
was higher for messages where the student had no chance to prepare before being accused of cheating. Overall, independent,
or experience, participants hold inaccurate beliefs about deception. 相似文献

We examined measurement invariance and age-related robustness of a short 15-item Big Five Inventory (BFI-S) of personality dimensions, which is well suited for applications in large-scale multidisciplinary surveys. The BFI-S was assessed in three different interviewing conditions: computer-assisted or paper-assisted face-to-face interviewing, computer-assisted telephone interviewing, and a self-administered questionnaire. Randomized probability samples from a large-scale German panel survey and a related probability telephone study were used in order to test method effects on self-report measures of personality characteristics across early, middle, and late adulthood. Exploratory structural equation modeling was used in order to test for measurement invariance of the five-factor model of personality trait domains across different assessment methods. For the short inventory, findings suggest strong robustness of self-report measures of personality dimensions among young and middle-aged adults. In old age, telephone interviewing was associated with greater distortions in reliable personality assessment. It is concluded that the greater mental workload of telephone interviewing limits the reliability of self-report personality assessment. Face-to-face surveys and self-administrated questionnaire completion are clearly better suited than phone surveys when personality traits in age-heterogeneous samples are assessed. 相似文献

Implicit motives represent nonconsciously represented dispositions to seek specific classes of incentives and to avoid corresponding classes of disincentives. Growing evidence suggests that the implicit power motive is associated with basal levels and reactivity of the gonadal steroid hormones testosterone in men and estradiol in women. It is also associated with increased release of stress hormones (cortisol, norepinephrine) in response to dominance challenges and social defeat. The implicit affiliation motive is linked to the release of progesterone: increases in progesterone are followed by increases in affiliation motivation, and arousal of affiliation motivation is associated with concurrent or subsequent progesterone increases. There is limited evidence for a role of vasopressin in achievement motivation. These findings point to a key role of the hypothalamus for implicit motives, a role that is consistent with the existence of function‐specific nuclei within this brain area. 相似文献

A potentially important variable that has received little attention in the literature is the locus of control (LOC) a caregiver holds for child improvement, including its influence on the caregiver's treatment compliance and on actual child improvement. In this study, 131 mother-child dyads were assessed across 1 year, to evaluate the utility of the LOC construct in a practice setting. Children were approximately 4 years old at the first assessment, and all of them had been diagnosed with a developmental disability. Mothers' compliance with treatment (mothers' attendance at sessions; teachers' ratings of mothers' support and knowledge) was tracked, and measures of child development status and mothers' locus of control were administered. Statistical results indicated that mothers' locus of control was not significantly correlated with children's gains in development over the year. The mothers' beliefs about whether the child or chance would be responsible for improvement were associated with lower compliance with treatment, whereas the mothers' beliefs that child improvement was attributable to professional intervention were associated with enhanced involvement in treatment. 相似文献

In laboratory tasks, caffeine has been shown to improve psychomotor performance. The aim of the present experiment was to assess the effects of caffeine on a skilled everyday life task in habitual caffeine consumers. The assessment of handwriting movements of 20 adults was performed following the administration of 0mg/kg (placebo), 1.5mg/kg, 3.0mg/kg or 4.5mg/kg of caffeine. A digitising tablet was used for the assessment of fine motor movements. Participants were asked to perform a simple writing task. Kinematic analysis of handwriting movements showed that, in comparison to placebo administration, high doses of caffeine (i.e., 4.5mg/kg) can produce improvements in handwriting as indicated by more fluent handwriting movements as well as an increase in maximum velocity and maximum positive and negative accelerations. The results suggest that higher doses of caffeine can enhance psychomotor performance. 相似文献

Age-related macular degeneration (AMD) was used as a case model to longitudinally study adaptation in affective well-being under a prevalent chronic health condition. Measures of positive and negative affect, obtained at 5 subsequent measurement occasions with 3-month intervals in between, were analyzed in 90 older adults diagnosed with AMD. The authors proposed a pattern of adaptation that shows initial decline in affective well-being after disease outbreak, followed by a turnaround into a restorative phase of increase, implying nonlinear intraindividual trajectories, with changes substantially related to disease duration. Analysis was conducted by means of a nonlinear mixed models approach. Results confirmed the hypothesized adaptation pattern for positive affect but not for negative affect, which was found more stable across measurement occasions. 相似文献

In the last decade, the Iowa Gambling Task (IGT) has become a widely employed neuropsychological research instrument for the investigation of executive function. The task has been employed in a wide range of formats, from 'manual' procedures to more recently introduced computerised versions. Computer-based formats often require that responses on the task should be artificially delayed by a number of seconds between trials to collect skin-conductance data. Participants, however, may become frustrated when they want to select from a particular deck in the time-limited versions--so that an unintended emotional experience of frustration might well disrupt a task presumed to be reliant on emotion-based learning. We investigated the effect of the various types of Iowa Gambling Task format on performance, using three types of task: the classic manual administration, with no time limitations; a computerised administration with a 6-s enforced delay; and a control computerised version which had no time constraints. We also evaluated the subjective experience of participants on each task. There were no significant differences in performance, between formats, in behavioural terms. Subjective experience measures on the task also showed consistent effects across all three formats-with substantial, and rapidly developing, awareness of which decks were 'good' and 'bad.' 相似文献

We assessed implicit needs for power, achievement, and affiliation in 323 U.S. college students using a Picture Story Exercise (PSE; McClelland, Koestner, & Weinberger, 1989) consisting of 6 picture cues and Winter's (1994) content coding system. Picture cues differed markedly in the amount of motive imagery they elicited and picture motive profiles closely resembled those reported by Schultheiss and Brunstein (2001) for a German student sample. Picture position influenced the expression of power and affiliation motivation, with affiliation motivation being most strongly expressed at the beginning and power motivation being most strongly expressed in the middle of the PSE. Women had higher affiliation motive scores than men. Asian Americans had higher affiliation motive scores than Whites, and African Americans had higher levels of achievement motivation than Asian Americans or Whites. PSE motive measures showed little or no overlap with questionnaire measures of impulsivity and anxiety (Behavioral Inhibition System-Behavioral Activation System scales; Carver & White, 1994) or specific motivational orientations (Personality Research Form; Jackson, 1984). Comparisons with Schultheiss and Brunstein's (2001) German sample indicate that U.S. students have higher achievement motivation and lower power motivation and activity inhibition scores than German students. 相似文献

Two experiments were performed regarding the effect of conscious control on handwriting fluency in healthy adults and ADHD children. First, 26 healthy students were asked to write a sentence under different conditions. The results indicate that automated handwriting movements are independent from visual feedback. Second, the writing performance of 12 children with ADHD was examined on their usual medication with methylphenidate and under placebo. In comparison to placebo, medication with methylphenidate resulted in a reduced fluency of handwriting. Automated handwriting movements could be elicited in children with ADHD on medication. The results suggest that both visual and mental control of handwriting movements affect the automation of handwriting movements. Furthermore, a simple training procedure was designed and performed in a case study of a boy with ADHD. 相似文献
