Cross-Cultural Comparisons of Adults’ Childhood Recollections: How are Peak-Experiences Described in China and Portugal?

Peak experiences are joyous and fulfilling moments in life, and thought to be associated with happiness and well-being. However, whether peak experiences vary from culture to culture is still under-researched. The current study investigated the autobiographical memories of peak experiences in Portugal and China. College students from Portugal and Mainland China (N = 161) reported their memory of a peak-experience occurring before the age of 14 and provided a self-rating on its enduring impact. We found that participants from Portugal reported peak-experiences involving a developmental landmark more frequently than did Mainland Chinese. In contrast, Mainland Chinese reported peak-experiences involving serenity more frequently than did Portuguese participants. Although Mainland Chinese provided more details about their peak-experiences, their narratives were more generic and emotionally mild. In particular, memory specificity (specific vs. general) significantly mediated the association between culture and developmental landmark, whereas memory emotionality (low arousal emotions) significantly mediated the link between culture and serenity. This study extends previous research on youthful peak-experiences to a cross-cultural context by incorporating measures of autobiographical memory to analyze variations between these two cultural groups.     

Notational modulation of the SNARC and the MARC (linguistic markedness of response codes) effect

Number magnitude and number parity representation are fundamental number representations. However, the representation of parity is much less understood than that of magnitude: Therefore, we investigated it by examining the (new) Linguistic Markedness of Response Codes (MARC) effect: Responses are facilitated if stimuli and response codes both have the same (congruent) linguistic markedness (even-right, odd-left) while incongruent conditions (even-left, odd-right) lead to interference. We examined systematically the MARC (for parity) and the Spatial Numerical Association of Response Codes (SNARC; for magnitude) effect for different number notations (positive Arabic, negative Arabic, number words) and with different methods of data analysis. In a parity judgement task, the SNARCeffect indicating a magnitude representation was replicated for all notations except for negative numerals. The MARCeffect was found for number words in all analyses, but less consistently for the other notations. In contrast, a correlational analysis of the reaction time (RT) data, as suggested by Sternberg (1969) using a nonmetric multi-dimensional scaling (MDS) procedure, produced a clear association of parity and response code for all notations (MARCeffect), but little evidence of the SNARCeffect. We discuss the extent to which these notation-specific MARC and SNARC effects constrain current models of number processing and elaborate on the possible functional locus of the MARC effect.     

Virtues in action – the new look of character traits

The present study aimed to take fresh look at the nature and psychological meaning of consistency in character traits and virtuous behaviour as manifested in everyday life. To this end, a 10‐day experience‐sampling study was conducted. Using smartphone technology, a sample of 83 working mothers and fathers provided a total of 4,342 momentary behavioural reports while being in the role of the parent versus being in the job role. Consistent with recent research on personality traits, the findings of the present study showed that people express a wide range of virtue states in their everyday lives. Within‐person changes in virtue states were not random but were contingent on people's current role context and also meaningfully related to their momentary affective experiences. At the same time, people's average level of virtue states, their degree of variation in virtue states, and their signature ways of reacting to role contexts turned out to be stable, trait‐like individual difference characteristics. Discussion focuses on the implications for the conception of character traits in scientific psychology and beyond.     

The genetic links between the big five personality traits and general interest domains

This is the first genetically informative study in which multiple informants were used to quantify the genetic and environmental sources of individual differences in general interests as well as the phenotypic and genetic links between general interests and Big Five personality traits. Self-reports and two peer ratings from 844 individuals, including 225 monozygotic and 113 dizygotic complete twin pairs, were collected. Multiple-rater scores (composites) revealed that the averaged levels of genetic and environmental effects on seven broad interest domains were similar to those on personality traits. Multivariate analyses showed that about 35% of the genetic and 9% of the environmental variance in interests were explained by personality domains, in particular by Openness. The findings suggest that interests cannot easily be considered as a byproduct of the interactions between personality genotypes and the environmental influences but rather as an internal regulation of behavior with an own genetic basis.     

Is acoustic evaluation in a non-primate mammal,the tree shrew,affected by context?

Sound categorisation plays a crucial role for processing ecological and social stimuli in a species’ natural environment. To explore the discrimination and evaluation of sound stimuli in human babies and nonhuman primates, a reciprocal habituation-dishabituation paradigm has been successfully introduced into auditory research. We applied the reciprocal paradigm for the first time to a non-primate mammal, the tree shrew (Tupaia belangeri), to examine to what extent non-primate mammals share the ability to evaluate communication calls with primates. Playback stimuli were three types of communication calls, differing distinctively in context and acoustic structure, as well as two artificial control sounds, differing solely in frequency. We assessed the attention towards the playback stimuli by the latency to respond to the test stimulus. Subjects evaluated pairs of communication call types as well as the artificial playback stimuli. Attention towards the test stimuli differed significantly in strength for one pair of communication calls, with subjects dishabituating faster to one category than the other. The comparison of a second pair of communication calls did not show significant differences. Interestingly, subjects also evaluated the artificial control sounds. Findings are only partly in line with results on human and non-human primates. They provided first evidence that in non-primate mammals acoustic evaluation is not solely affected by the sound-associated context but is also linked to unusualness and acoustic cues, such as peak frequency.     

Age differences in financial decision making: The benefits of more experience and less negative emotions

The emerging literature on aging and decision making posits that decision‐making competence changes with age, as a result of age differences in various cognitive and noncognitive individual‐differences characteristics. In a national life‐span sample from the United Kingdom (N = 926), we examined age differences in financial decisions, including performance measures of sunk cost and credit card repayment decisions, and self‐report measures of money management and financial decision outcomes. Participants also completed four individual‐differences characteristics that have been proposed as relevant to financial decision making, including two cognitive ones (numeracy and experience‐based knowledge) and two noncognitive ones (negative emotions about financial decisions). First, we examined how age was related to the four financial decision‐making measures and the four individual‐differences characteristics. Older age was correlated to better scores on each of the four financial decision‐making measures, more experience‐based knowledge, less negative emotions about financial decisions, whereas numeracy and motivation were not significantly correlated with age. Second, we found that considering both the two cognitive and the two noncognitive individual‐differences characteristics increased predictions of financial decision making, as compared with considering either alone. Third, we examined how these four individual‐differences characteristics contributed to age differences in financial decision making. Older adults' higher levels of experience‐based knowledge and lower levels of negative emotions seemed to especially benefit their financial decision making. We discuss implications for theories on aging and decision making, as well as for interventions targeting financial decisions.     

Finding a Life Worth Living: Meaning in Life and Graduation from College

Graduation from college is an important milestone for young adults, marked by mixed emotions and poignancy, and therefore is an especially salient context for studying meaning in life. The present research used experience‐sampling methodology to examine the antecedents and consequences of students' experience of meaning in life over the course of graduation. Participants were 74 graduating students who provided a total of 538 reports over the span of 3 days, including commencement day. Increased levels of state meaning in life during the days around commencement were linked to spending time with people in general and with family in particular, and thinking about one's years in college. Thinking about one's years in college mediated the effects of present company on state meaning in life. Graduates who experienced higher levels of state meaning in life during the days around their commencement ceremony had higher trait levels of meaning in life 1 week following commencement. We discuss how making meaning of a poignant experience has implications for healthy psychological development. Copyright © 2016 European Association of Personality Psychology
