Age Differences Across Adulthood in Interpretations of Situations and Situation–Behaviour Contingencies for Big Five States

In the last two decades, a burgeoning literature has begun to clarify the processes underlying personality traits and momentary trait‐relevant behaviour. However, such work has almost exclusively investigated these questions in young adults. During the same period, much has been learned about adult personality trait development but with scant attention to the momentary processes that contribute to development. The current work connects these two topics, testing developmental questions about adult age differences and thus examining how age matters to personality processes. The study examines how four important situation characteristics are experienced in everyday life and how situations covary with Big Five trait‐relevant behaviour (i.e. situation–behaviour contingencies). Two samples were collected (total N = 316), each assessing three age groups: young, middle‐aged, and older adults. Using experience sampling method, participants completed reports four or five times per day across a representative period of daily life. Results suggested age differences in how situations are experienced on average, in the variability around these average situation experiences, and in situation–behaviour contingencies. The results therefore highlight that, across adulthood, age groups experience chronically different situations, differ in how much the situations they experience vary moment to moment, and differ in how much situation experience predicts their enactment of traits. © 2019 European Association of Personality Psychology     

Measurement of cognitive functions in experts and elite athletes: A meta‐analytic review

An extraordinary physiological capacity combined with remarkable motor control, perception, and cognitive functioning is crucial for high performance in sports. Tests that assess the physical abilities are already well established. Moreover, a growing area of research evolved in the recent past that is particularly concerned with the basic cognitive functions by means of neurocognitive tests in experts and elite athletes. The aim of this meta‐analysis (k = 19) is to quantify differences among experts and nonexperts as well as elite athletes and non‐elite athletes. In addition, it aims to assemble and compare previous research and analyze possible differences in cognitive functions depending on age, skill level, and used cognitive tasks. Overall, the mean effect size was small to medium (r = 0.22), indicating superior cognitive functions in experts and elite athletes. The factor of skill definition significantly differentiates the cognition–expertise relationship. In contrast, differences in age groups and cognitive areas appeared but were not significant. Future research should prefer the elite rather than the expert definition and distinguish between high‐performance and amateur athletes. Furthermore, the findings suggest that it can be beneficial for coaches and sport clubs to integrate cognitive tests as an additional tool for scouting and for optimizing the athletic development of their players.     

Disruption of order information by irrelevant items: a serial recognition paradigm

Irrelevant speech effect (ISE) is defined as a decrement in visually presented digit-list short-term memory performance due to exposure to irrelevant auditory material. Perhaps the most successful theoretical explanation of the effect is the changing state hypothesis. This hypothesis explains the effect in terms of confusion between amodal serial order cues, and represents a view based on the interference caused by the processing of similar order information of the visual and auditory materials. An alternative view suggests that the interference occurs as a consequence of the similarity between the visual and auditory contents of the stimuli. An important argument for the former view is the observation that ISE is almost exclusively observed in tasks that require memory for serial order. However, most short-term memory tasks require that both item and order information be retained in memory. An ideal task to investigate the sensitivity of maintenance of serial order to irrelevant speech would be one that calls upon order information but not item information. One task that is particularly suited to address this issue is serial recognition. In a typical serial recognition task, a list of items is presented and then probed by the same list in which the order of two adjacent items has been transposed. Due to the re-presentation of the encoding string, serial recognition requires primarily the serial order to be maintained while the content of the presented items is deemphasized. In demonstrating a highly significant ISE of changing versus steady-state auditory items in a serial recognition task, the present finding lends support for and extends previous empirical findings suggesting that irrelevant speech has the potential to interfere with the coding of the order of the items to be memorized.     

Personality characteristics of research volunteers

We evaluated Big Five personality factor differences between research volunteers and nonvolunteers. In the first study, 158 military officers were asked to participate in a mail survey. The personality scores of the officers were available from an archival data set. In our second study, adult siblings from large families were invited to participate in extensive clinical epidemiological evaluations. The personality scores of volunteers (N = 55) and nonvolunteers from the same families (N = 29) were estimated from sibling ratings made by those who participated in the study. In both studies, respondents, compared to nonrespondents, were found to be significantly lower in Neuroticism and higher in Conscientiousness. The second study further indicated respondents as being higher in Extraversion and Agreeableness. Copyright © 2007 John Wiley & Sons, Ltd.     

Semantic interference on a phonological task in illiterate subjects

Previous research suggests that learning an alphabetic written language influences aspects of the auditory-verbal language system. In this study, we examined whether literacy influences the notion of words as phonological units independent of lexical semantics in literate and illiterate subjects. Subjects had to decide which item in a word- or pseudoword pair was phonologically longest. By manipulating the relationship between referent size and phonological length in three word conditions (congruent, neutral, and incongruent) we could examine to what extent subjects focused on form rather than meaning of the stimulus material. Moreover, the pseudoword condition allowed us to examine global phonological awareness independent of lexical semantics. The results showed that literate performed significantly better than illiterate subjects in the neutral and incongruent word conditions as well as in the pseudoword condition. The illiterate group performed least well in the incongruent condition and significantly better in the pseudoword condition compared to the neutral and incongruent word conditions and suggest that performance on phonological word length comparisons is dependent on literacy. In addition, the results show that the illiterate participants are able to perceive and process phonological length, albeit less well than the literate subjects, when no semantic interference is present. In conclusion, the present results confirm and extend the finding that illiterate subjects are biased towards semantic-conceptual-pragmatic types of cognitive processing.     

Self-esteem reconsidered: unstable self-esteem outperforms level of self-esteem as vulnerability marker for depression

Previous studies have built up evidence that an unstable self-esteem is associated with vulnerability to depression and that it outperforms level of self-esteem as a predictor for symptoms of depression. However, most of these studies have used student samples exclusively to investigate the role of self-esteem instability in depression vulnerability. Our present study used samples of currently depressed inpatients, formerly depressed individuals, and never-depressed controls to investigate the relationship between self-esteem instability and depression. In addition, we examined the predictive validity of self-esteem instability in predicting future depressive symptoms. The results indicate that self-esteem instability is associated with depression and vulnerability to depression. Furthermore, self-esteem instability interacted with perceived stress variability and depressed mood variability in predicting future depressive symptomatology at six months follow-up. These results are in line with the diathesis-stress model and support the hypothesis that self-esteem instability might be more important than level of self-esteem in predicting vulnerability to depression.     

Memory trace stabilization leads to large-scale changes in the retrieval network: a functional MRI study on associative memory

Spaced learning with time to consolidate leads to more stabile memory traces. However, little is known about the neural correlates of trace stabilization, especially in humans. The present fMRI study contrasted retrieval activity of two well-learned sets of face-location associations, one learned in a massed style and tested on the day of learning (i.e., labile condition) and another learned in a spaced scheme over the course of one week (i.e., stabilized condition). Both sets of associations were retrieved equally well, but the retrieval of stabilized association was faster and accompanied by large-scale changes in the network supporting retrieval. Cued recall of stabilized as compared with labile associations was accompanied by increased activity in the precuneus, the ventromedial prefrontal cortex, the bilateral temporal pole, and left temporo–parietal junction. Conversely, memory representational areas such as the fusiform gyrus for faces and the posterior parietal cortex for locations did not change their activity with stabilization. The changes in activation in the precuneus, which also showed increased connectivity with the fusiform area, are likely to be related to the spatial nature of our task. The activation increase in the ventromedial prefrontal cortex, on the other hand, might reflect a general function in stabilized memory retrieval. This area might succeed the hippocampus in linking distributed neocortical representations.     

The Relationship Between Spirituality,Health Beliefs,and Health Behaviors in College Students

The United States is a country in which religion and spirituality play a significant role in people’s lives. The relationship between religion, spirituality and health has long been investigated. However, most of these studies have focused only on patient populations and the elderly. The present study examines whether the same pattern of relations reported earlier is seen in a sample of healthy, college students using measures of both spirituality and religion. Health beliefs and behaviors were also examined. The results show that individuals with higher spirituality scores are more active and hold difference health beliefs than those who scored in the low spirituality group. However, some contradictions from previous research were reported in this sample. The study suggests religion may have some different pattern of relations in the overall health and health behaviors of younger, healthier populations.

Cross-national comparisons of the association between alcohol consumption and deliberate self-harm in adolescents

How differences in drinking patterns may affect the impact of alcohol consumption on deliberate self-harm among adolescents is explored in this international comparative study. Schools in Australia, Belgium, England, Hungary, Ireland, the Netherlands, and Norway (N = 30,532) were surveyed. In all countries the risk of deliberate self-harm was significantly elevated among adolescents who reported some or numerous episodes of intoxication, controlling for confounding factors. The results support the assumption that intoxication is significantly related to the association between alcohol consumption and deliberate self-harm in adolescents.     

Spectral tilt as a cue to word segmentation in infancy and adulthood

Across a variety of tasks, adults respond differently to syllables with multiple stress cues than to syllables with only one cue to stress. This series of experiments was designed to explore how infants and adults use partial stress as a cue to word boundaries. In the first experiment, 9-month-old infants treated syllables with only one cue to stress (spectral tilt) as a strong cue to word boundaries. The second experiment shows that whereas adults treat syllables with multiple cues to stress as word onsets, they do not consider syllables marked only by spectral tilt to be strong indicators of word boundaries. Thethird experiment shows that 1-year-old infants are more adultlike than 9-month-olds in their use of stress cues. Taken together, these results suggest a rapid development of stress cue knowledge in infancy, perhaps due to infants' experience with word segmentation.
