Values and learning approaches of students at an international university

This study indicates that values are statistically significant precursors to approaches to learning in a cohort of predominantly Bulgarian, German and Romanian students studying at a German university where the language of instruction in all subject areas is English. Values have been measured with the Portrait Values Questionnaire (Schwartz et al. 2001), and approaches to learning have been assessed by the Study Process Questionnaire (Biggs, 1987). The relationships between values and approaches to learning have been estimated by canonical correlation analysis. Results of the analysis suggest that values can be linked to learning approaches in a situation where students have left their home countries to undertake tertiary studies in a new social, cultural and educational environment. Four distinct pairings between values and learning approaches emerge whereby: (a) self-aggrandisement is linked to the achievement learning variable, (b) conservatism relates to the surface learning variable, (c) self-directedness is linked to the deep learning variable and (d) benevolent change is related to the learning strategies variable. The analyses for this research were conducted while the second author was a visiting scholar at the Flinders University Institute of International Education in Adelaide, South Australia.

Disturbed behavioural adaptability as related to reproductive hormones and emotional states during the menstrual cycle

The relationship between the incapacity to adapt behaviour to external requirements and biological irregularities of the menstrual cycle was investigated in 30 healthy females divided according to a questionnaire on behavioural adaptability into good (GAs) and bad (BAs) adaptors. Emotional states and blood samples for determination of hormones were obtained on ten defined days of the menstrual cycle, which were individually synchronized to six phases according to biological indicators. Comparison of GAs and BAs revealed that the incapacity of behavioural adaptation is associated with higher neuroticism related traits and states and that BAs exhibited higher cortisol and testosterone levels, lower luteal and follicular levels of estrogen, and lower luteal levels of progesterone. Furthermore, significantly more BA subjects suffered from corpus luteum deficiency. Results are discussed with respect to chronobiological biobehavioural mechanisms. © 1998 John Wiley & Sons, Ltd.     

Gricean Expectations in Online Sentence Comprehension: An ERP Study on the Processing of Scalar Inferences

There is substantial support for the general idea that a formalization of comprehenders' expectations about the likely next word in a sentence helps explaining data related to online sentence processing. While much research has focused on syntactic, semantic, and discourse expectations, the present event‐related potentials (ERPs) study investigates neurolinguistic correlates of pragmatic expectations, which arise when comprehenders expect a sentence to conform to Gricean Maxims of Conversation. For predicting brain responses associated with pragmatic processing, we introduce a formal model of such Gricean pragmatic expectations, using an idealized incremental interpreter. We examine whether pragmatic expectancies derived from this model modulate the amplitude of the N400, a component that has been associated with predictive processing. As part of its parameterization, the model distinguishes genuine pragmatic interpreters, who expect maximally informative true utterances, from literal interpreters, who only expect truthfulness. We explore the model's non‐trivial predictions for an experimental setup which uses picture‐sentence verification with ERPs recorded at several critical positions in sentences containing the scalar implicature trigger some. We find that Gricean expectations indeed affect the N400, largely in line with the predictions of our model, but also discuss discrepancies between model predictions and observations critically.     

Validity of retrospective time‐use reports in old age

In a sample of N=83 participants aged between 72 and 97, we assessed the accuracy of time budgets originating from the Yesterday Interview (YI; Moss and Lawton, 1982) by means of comparison with in‐situ assessments based on the Experience‐Sampling Method (ESM; e.g. Csikszentmihalyi and Larson, 1987). We examined convergent and discriminant correlation patterns from indices of activity participation, location, company, and mood collected via both methods. The correspondence between the two methods appeared acceptable. Furthermore, we explored whether (a) length of the retention interval, (b) congruence with pre‐existing knowledge, and (c) congruence of the locations of encoding and retrieval accounted for (in)accuracy of recall. We also analysed the degree to which age and cognitive functioning explained performance differences. While we found discrepancies between YI and ESM to be hardly attributable to context effects or differences in cognitive functioning, there was an age effect. Finally, the sensitivity of the two methods to detect differences between groups was found to be largely equivalent but hardly sufficiently convergent. Copyright © 1999 John Wiley & Sons, Ltd.     

Context and Complexity in Incremental Sentence Interpretation: An ERP Study on Temporal Quantification

The present event-related potential (ERP) study used picture–sentence verification to investigate the neurolinguistic correlates of the online processing of compositional-semantic information. To this end, we examined context effects on sentences involving temporal adverbial quantification likeJana war jeden Morgen schwimmen an den Arbeitstagen (“Jana went for a swim every morning during the working week”). We tested whether the conceptual complexity associated with quantifying over time intervals leads to delayed predictions regarding the upcoming words in a sentence. The present study replicated previous results relating to quantification over individuals, which are conceptually less complex than time intervals. Analogous to previous studies, false vs. true sentences elicited an N400 whenever contextual cues did not permit a potential revision of a locally assigned truth value. The present results are compatible with an approach under which contextual cues are immediately considered for predicting how a sentence continues. The fact that the contextual complexity did not lead to processing delays indicates that the processing system quickly abstracts away from the conceptual complexity associated with the linguistic input if such an abstraction is possible.     

Manual rotation training improves direction-estimations in a virtual environmental space

This study investigated in a virtual environment, whether the training of a small-scale ability, i.e., manual or mental rotation, has an influence on the large-scale ability to estimate a direction. Ninety-six participants completed a direction estimation task as a pretest and then received either a manual rotation or a mental rotation training or played a nonspatial computer game. After that they completed the direction estimation task once again. The results showed that the direction estimation error decreased from the pre- to posttest only for the manual rotation training group. For that, the small-scale spatial ability was at least partially related to the large-scale ability, which supports the Partial Dissociation Model.     

Affect of the unconscious: Visually suppressed angry faces modulate our decisions

Emotional and affective processing imposes itself over cognitive processes and modulates our perception of the surrounding environment. In two experiments, we addressed the issue of whether nonconscious processing of affect can take place even under deep states of unawareness, such as those induced by interocular suppression techniques, and can elicit an affective response that can influence our understanding of the surrounding environment. In Experiment 1, participants judged the likeability of an unfamiliar item—a Chinese character—that was preceded by a face expressing a particular emotion (either happy or angry). The face was rendered invisible through an interocular suppression technique (continuous flash suppression; CFS). In Experiment 2, backward masking (BM), a less robust masking technique, was used to render the facial expressions invisible. We found that despite equivalent phenomenological suppression of the visual primes under CFS and BM, different patterns of affective processing were obtained with the two masking techniques. Under BM, nonconscious affective priming was obtained for both happy and angry invisible facial expressions. However, under CFS, nonconscious affective priming was obtained only for angry facial expressions. We discuss an interpretation of this dissociation between affective processing and visual masking techniques in terms of distinct routes from the retina to the amygdala.
