Product information, hedonic evaluation, and purchase decision: an experimental study of orange juice
2007
AbstractTwo randomly sampled groups of subjects were endowed with real budgets and placed in 5 different budget/price situations. In each situation they had to evaluate 6 orange juices and complete a demand table. At the end of the experiment, one demand table was randomly selected and participants had to buy the corresponding products. In one group, participants choose after looking at the packaging in the other they could also taste the products. Results show that participants who chose without tasting, made quicker decisions, selected a larger number of variants and were more influenced by prices than those who could taste the products. Although choices appeared very heterogeneous, most …
Activation of a Sweet Taste Receptor by Oleanane-Type Glycosides from Wisteria sinensis
2022
The phytochemical study of Wisteria sinensis (Sims) DC. (Fabaceae), commonly known as the Chinese Wisteria, led to the isolation of seven oleanane-type glycosides from an aqueous-ethanolic extract of the roots. After successive purifications by various chromatographic methods, like solid/liquid chromatographic methods, vacuum liquid chromatography (VLC), medium pressure liquid chromatography (MPLC), on normal and reverse phase (RP-18 silica gel), and size exclusion chromatography on Sephadex L, their structures were elucidated by an extensive 600 MHz NMR analysis including 1D and 2D NMR experiments as well as ESI-MS. Among the seven isolated saponins, two have never been reported before : 3…
Testing cross-lagged relationships between work-related rumination and well-being at work in a three-wave longitudinal study across 1 and 2 years
2019
The aim of this three-wave longitudinal study conducted among 664 Finnish employees was to examine the cross-lagged relationships between various work-related ruminative thoughts (affective rumination, problem-solving pondering, lack of detachment from work) during off-job time and employee well-being (exhaustion, vigour). We tested normal, reversed, and reciprocal temporal relationships across 1 and 2 years using structural equation modelling. The analyses lent most support to the reversed temporal relationships, showing first that high exhaustion predicted low problem-solving pondering 2 years later and second, that high vigour predicted low affective rumination both 1 and 2 years later. …
Do Unnecessary Tasks Impair Performance Because They Harm Living a Calling? : Testing a Mediation in a Three-Wave Study
2021
This three-wave study explored whether living a calling (at work) mediated the relation between unnecessary tasks (time wasting work tasks) and socio-contextual performance at work (cynicism, organizational citizenship behavior). Participants were 518 Finnish white- and blue-collar employees, who were followed up in 2018, 2019, and 2020. The results of structural equation modeling showed that unnecessary tasks at Time 1 related negatively to living a calling at Time 2, which, in turn, related to cynicism and organizational citizenship behavior at T3. Thus, living a calling mediated the relation between unnecessary tasks and the outcomes. We found no evidence for the moderator role of living…
On the role of the upper part of words in lexical access: evidence with masked priming.
2012
More than 100 years ago, Huey (1908) indicated that the upper part of words was more relevant for perception than the lower part. Here we examined whether mutilated words, in their upper/lower portions (e.g., , , , ), can automatically access their word units in the mental lexicon. To that end, we conducted four masked repetition priming experiments with the lexical decision task. Results showed that mutilated primes produced a sizeable masked repetition priming effect. Furthermore, the magnitude of the masked repetition priming effect was greater when the upper part of the primes was preserved than when the lower portion was preserved –this was the case not only when the mutilated words we…
Evaluating Assessment. Validation with PLS-SEM of ATAE Scale for the Analysis of Assessment Tasks
2020
One of the essential functions of university teachers lies in the decision-making process regarding the various components included in assessment process design, where the quality of assessment tasks is a key aspect. This study presents both validation of an instrument for students to evaluate the assessment tasks and the model that upholds the relationships between constructs that characterise the assessment tasks. Working from a review of the literature, a theoretical model has been devised featuring the characteristics of the assessment tasks and the relationships between them. The Analysis of the Assessment and Learning Tasks questionnaire (ATAE) has been designed to check them, based o…
The evaluation of dual-task conditions on static postural control in the older adults: a systematic review and meta-analysis protocol
2019
Abstract Background In postural stability evaluation, the dual-task concept is often adopted in order to create a more challenging situation. The dual-task consists of performing simultaneously two tasks, a primary static or dynamic motor task and an additional secondary cognitive task. Usually, a multitask condition leads to a reduction in the postural control performance, especially in older adults. Considering the wide spectrum of secondary task conditions existing in scientific literature, the present manuscript aims to write a peer-reviewed protocol that will be used in a systematic review and meta-analysis performed to identify the effects of different secondary tasks conditions in a …
Una revisión del concepto de «acumulación por desposesión» de D. Harvey
2019
espanolEl objetivo del presente articulo sera realizar una revision critica de la interpretacion realizada por D. Harvey del concepto de «acumulacion originaria» expuesto por K. Marx en El Capital. A traves del analisis de los escritos donde Marx aborda esta cuestion, trataremos de demostrar que la aportacion principal de Harvey -reinterpretar la acumulacion originaria, no como proceso fundacional de las condiciones necesarias para la produccion capitalista, sino como proceso continuo y permanente utilizado para restablecer las condiciones optimas de la acumulacion de capital mediante la conquista de nuevos espacios- se sustenta en una interpretacion parcial de los textos de critica de la e…
Sequential effects in the lexical decision task: the role of the item frequency of the previous trial.
2003
Two lexical decision experiments were conducted to determine whether there is a specific, localized influence of the item frequency of consecutive trials (i.e., first-order sequential effects) when the trials are not related to each other. Both low-frequency words and nonwords were influenced by the frequency of the precursor word (Experiment 1). In contrast, high-frequency words showed little sensitivity to the frequency of the precursor word (Experiment 2), although they showed longer reaction times for word trials preceded by a nonword trial. The presence of sequential effects in the lexical decision task suggests that participants shift their response criteria on a trial-by-trial basis.
The frequency effect for pseudowords in the lexical decision task
2005
Four experiments were designed to investigate whether the frequency of words used to create pseudowords plays an important role in lexical decision. Computational models of the lexical decision task (e.g., the dual route cascaded model and the multiple read-out model) predict that latencies to low-frequency pseudowords should be faster than latencies to high-frequency pseudowords. Consistent with this prediction, results showed that when the pseudowords were created by replacing one internal letter of the base word (Experiments 1 and 3), high-frequency pseudowords yielded slower latencies than low-frequency pseudowords. However, this effect occurred only in the leading edge of the response …
