Theorizing the Temporal Aspect of Ikigai or Life Worth Living among Japanese University Students: a Mixed-Methods Approach

Although cross-cultural and non-Western studies have advanced our knowledge on well-being, many studies have adopted English words including ‘happiness’ as their guiding concepts, which may have limited and biased their insight. The current study is part of a larger mixed-methods project that theorizes how Japanese university students pursue ikigai or a life worth living. The first qualitative study, based on 27 photo-elicitation interviews, generated a grounded theory of houkousei, or life directionality. Our qualitative findings suggested that when students formed explicit associations among the past, present, and future, they gained strong ikigai feelings. These associations were developed either cognitively by mentally associating existing present experiences with the past or future, or behaviourally by strategically choosing current experiences more pertinent to the past or future than alternatives. These actions resulted in two subjective states: life legacy and life momentum. Life legacy was the perception that one’s past had meaningfully contributed to his or her present experiences, life, and self. Life momentum meant the belief that one’s present experiences were helping him or her achieve the desired future. Lastly, having defining past experiences and setting clear goals both facilitated the associative actions. To further validate this theory, we collected online survey data from a national sample of 672 Japanese students. Our quantitative results, based on partial least squares structural equation modelling (PLS-SEM), largely supported our theoretical model. Our findings are discussed in light of the ikigai and eudaimonic well-being literatures.

     

Dominance assertion in male chimpanzees (Pan troglodytes)

The social relations of three adult males in a captive chimpanzee group were evaluated for 12 months. The observations encompassed a period of transition in the dominance hierarchy providing an opportunity to assess behavioral patterns involved in the initiation of status changes. This study shows that dominance in the chimpanzee is expressed primarily through ritualized and non-contact behavior rather than by overt aggression. In particular, display behavior is important for indicating dominance rank, in communicating aggressive intent, and as a prelude to status struggles. The functional relationships between status, displays and other socio-sexual behavior patterns are presented.     

The Role of Children's Neurophysiological Functioning in the Links Between Emotion-Parenting Behaviors and Child Anxiety Symptoms: A Biological Sensitivity to Context Framework

A plethora of data supports links between parenting behaviors and child anxiety, but few studies have examined factors that can contribute to variability in these relations. Adopting a biological sensitivity to context framework, this study explored the role of children's physiological stress reactivity in the links between emotion-parenting and child anxiety symptoms in a group of Chinese families. Sixty-one parent–child dyads (child M_age = 8.21 years, SD = 1.40, range = 6–12 years) participated in an acute stress protocol, from which children's physiological (cortisol and respiratory sinus arrhythmia) responses to a social speech task were recorded. Participants then completed questionnaires assessing parents’ emotion-parenting behaviors and children's anxiety symptoms. Results showed that the relation between supportive emotion-parenting and child anxiety was stronger in the context of greater child RSA suppression to acute stress, such that children higher in RSA suppression exhibited lower anxiety symptoms when supportive emotion-parenting was higher than when it was lower. Thus, these findings supported the biological sensitivity to context model. No significant moderation effect was detected for cortisol reactivity or recovery. Instead, exploratory mediation analyses showed that supportive emotion-parenting was negatively related to child anxiety via greater cortisol recovery. There was also a significant indirect path where unsupportive emotion-parenting was related to blunted cortisol recovery, which in turn was associated with higher child anxiety. The results highlight the importance of coaching parents to respond in supportive ways to children's emotional expressions, particularly in the context of greater child reactivity, to help buffer against childhood anxiety symptoms.     

The Associations between Mothers’ and Grandmothers’ Depressive Symptoms,Parenting Stress,and Relationship with Children: An Actor–Partner Interdependence Mediation Model

Three-generation households that include parents and grandparents raising children together have become increasingly common in China. This study examined the relations among depressive symptoms, parenting stress, and caregiver–child relationships in the mother–grandmother dyadic context. Participants were mothers and grandmothers from 136 three-generation households. Results from Actor–Partner Interdependence Mediation Modeling indicated that mothers’ depressive symptoms were indirectly related to mother–child conflict/closeness through own parenting stress; grandmothers’ depressive symptoms were indirectly related to grandmother–child conflict through own parenting stress. Mothers’ depressive symptoms were indirectly related to grandmothers’ conflict with children through grandmothers’ parenting stress, and grandmothers’ depressive symptoms were indirectly related to mothers’ conflict/closeness with children through mothers’ parenting stress. The relation between mothers’ parenting stress and mother–child closeness was stronger than the relation between grandmothers’ parenting stress and grandmother–child closeness. Findings highlight the implications of using a family system perspective and the dyadic approach in understanding and improving family functioning in Chinese three-generation households.     

Timing the “magical number seven”: Presentation rate and regularity affect verbal working memory performance

The informative value of time and temporal structure often remains neglected in cognitive assessments. However, next to information about stimulus identity we can exploit temporal ordering principles, such as regularity, periodicity, or grouping to generate predictions about the timing of future events. Such predictions may improve cognitive performance by optimising adaptation to dynamic stimuli. Here, we investigated the influence of temporal structure on verbal working memory by assessing immediate recall performance for aurally presented digit sequences (forward digit span) as a function of standard (1000 ms stimulus-onset-asynchronies, SOAs), short (700 ms), long (1300 ms) and mixed (700–1300 ms) stimulus timing during the presentation phase. Participant's digit spans were lower for short and mixed SOA presentation relative to standard SOAs. This confirms an impact of temporal structure on the classic “magical number seven,” suggesting that working memory performance can in part be regulated through the systematic application of temporal ordering principles.     

Teaching caregivers to implement mand training using speech generating devices

Individuals with developmental disabilities often do not develop vocal repertoires, thus requiring the use of augmentative devices. Teaching caregivers to conduct communication training with their children may be one way to foster communication with their device in the natural environment. This study replicates Rosales, Stone and Rehfeldt (2009), but using an augmentative device. Behavioral skills training was used to teach caregivers to implement mand training procedures. Caregivers quickly learned to implement mand training with their children and independent mands increased from pretraining to posttraining observations for 2 out of 3 children.     

A comparison of isolated and synthesized contingencies in functional analyses

Recently, researchers have compared the utility of isolated versus synthesized contingencies in functional analysis (FA) methodology (e.g., Fisher et al., 2016; Slaton et al., 2017). A limitation of these studies is that there were other differences across FA methodologies (e.g., design, contingency) that did not allow for isolation of the influence of isolated versus synthesized contingencies. Therefore, the current study compared outcomes of FAs that involved isolated versus synthesized contingencies for problem behavior of 5 children while controlling for these other differences across FAs (Experiment 1). Next, the current study compared the effects of interventions based on the functions identified in the isolated and synthesized contingencies for each participant (Experiment 2). Results indicated isolated contingency FAs produced differentiated responding for 1 or both functions for all 5 participants, and there were little to no differences between treatments informed by isolated and synthesized contingency FAs.
