Task performance and metacognitive experiences in problem-solving

The effects of task performance on metacognitive experiences and relations between task performance and metacognitive experiences in problem-solving were examined with 69 Japanese undergraduate students. The task was a puzzle called the cross breaker, consisting of seven pieces, and several figures were constructed by using those seven pieces. Eight types of metacognitive experiences, before and after performing the task, were rated. Participants were classified into Success and Failure groups based on their task performance. Use of all but two metacognitive experiences differed between the groups. There were medium to high positive and negative correlations for metacognitive experiences with performance after the puzzle task, whereas metacognitive experiences before the task generally had no significant correlations with performance. Despite small N, participants' metacognitive experiences seemed to reflect their actual performance, suggesting that people obtain information from their performance and use it to revise their metacognitive experiences. Furthermore, metacognitive experiences may help people solve similar problems in the future.     

Perception of emotional tears with body postures,visual scenes,and written scenarios

Emotional tears tend to increase perceived sadness in facial expressions. However, it is unclear whether tears would still be seen as an indicator of sadness when a tearful face is observed in an emotional context (e.g., a touching moment during a wedding ceremony). We examine the influence of context on the sadness enhancement effect of tears in three studies. In Study 1, participants evaluated tearful or tearless expressions presented without body postures, with emotionally neutral postures, or with emotionally congruent postures (i.e., postures indicating the same emotion as the face). The results show that the presence of tears increases the perceived sadness of faces regardless of context. Similar results are found in Studies 2 and 3, which used visual scenes and written scenarios as contexts, respectively. Our findings demonstrate that tears on faces reliably indicate sadness, even in the presence of contextual information that suggests non-sadness emotions.     

Links between real and virtual networks: a comparative study of online communities in Japan and Korea.

The present study explores how online communities affect real-world personal relations based on a cross-cultural survey conducted in Japan and Korea. Findings indicate that the gratifications of online communities moderate the effects of online communities on social participation. Online communities are categorized into a real-group-based community and a virtual-network-based community. The membership of real-group-based online community is positively correlated with social bonding gratification and negatively correlated with information- seeking gratification. Japanese users prefer more virtual-network-based online communities, while their Korean counterparts prefer real-group-based online communities. Korean users are more active in online communities and seek a higher level of socializing gratifications, such as social bonding and making new friends, when compared with their Japanese counterparts. These results indicate that in Korea, personal relations via the online community are closely associated with the real-world personal relations, but this is not the case in Japan. This study suggests that the effects of the Internet are culture-specific and that the online community can serve a different function in different cultural environments.     

The Effect of Positive Emotions with Different Arousal Levels on Thought–Action Repertoires1,2

This study examined whether the induction of different states of arousal via positive emotions broadens thought–action repertoires. Sixty-two Japanese undergraduate and graduate students were randomly assigned to (a) high-arousal positive emotion, (b) low-arousal positive emotion, and (c) neutral groups, after which they watched a 3-min film clip. Participants completed the Affect Grid to confirm their mood state before and after watching the film. Following this, they completed the Twenty Statements Test, which measures thought–action repertoires. A one-way analysis of variance was conducted on the Twenty Statements Test score. The results showed that high-arousal positive emotion broadened thought–action repertoires to a greater extent than did low-arousal positive emotion and the neutral state, while low-arousal positive emotion broadened such repertoires to a greater extent than did the neutral state. We discuss the different effects of high- and low-arousal positive emotions on thought–action repertoires.     

Online/offline self-disclosure to offline friends and relational outcomes in a diary study: The moderating role of self-esteem and relational closeness

Previous work suggests that the experiences of online and offline self-disclosure are heterogeneous among individuals. Yet little work has been done to identify the moderating role of individual characteristics and pre-existing relationship characteristics on the diverse relational outcomes. The present study using a 7-day diary design examined whether individuals' self-esteem level and relational closeness would moderate the relationships between online and offline self-disclosure to offline friends and two relational outcomes, that is, relationship satisfaction and trust in friendships. The analyses on 686 diary responses from 98 participants revealed that offline self-disclosure generally predicted greater relationship satisfaction and trust in friendships, whereas the role of online self-disclosure was not statistically significant. More importantly, self-esteem moderated the pattern associated with offline self-disclosure but not that with online self-disclosure. Specifically, offline self-disclosure predicted greater benefits to people with lower self-esteem relative to people with higher self-esteem. Moreover, pre-existing relational closeness moderated the relationship between offline self-disclosure and trust in friendships such that casual friendships benefited more from offline self-disclosure than close friendships did. The present study highlights the importance of personal characteristics and relationship characteristics in understanding the heterogeneous relational influence of different communication modes.     

Long-term memory of color stimuli in the jungle crow (Corvus macrorhynchos)

Wild-caught jungle crows (n = 20) were trained to discriminate between color stimuli in a two-alternative discrimination task. Next, crows were tested for long-term memory after 1-, 2-, 3-, 6-, and 10-month retention intervals. This preliminary study showed that jungle crows learn the task and reach a discrimination criterion (80% or more correct choices in two consecutive sessions of ten trials) in a few trials, and some even in a single session. Most, if not all, crows successfully remembered the constantly reinforced visual stimulus during training after all retention intervals. These results suggest that jungle crows have a high retention capacity for learned information, at least after a 10-month retention interval and make no or very few errors. This study is the first to show long-term memory capacity of color stimuli in corvids following a brief training that memory rather than rehearsal was apparent. Memory of visual color information is vital for exploitation of biological resources in crows. We suspect that jungle crows could remember the learned color discrimination task even after a much longer retention interval.     

Changes in brain tryptophan metabolism elicited by ageing, social environment, and psychological stress in mice

The kynurenine (KYN) pathway, which is initiated by indoleamine 2,3-dioxygenase (IDO), is a tryptophan (TRP) metabolic pathway. It shares TRP with the serotonin (5-hydroxytryptamine, 5-HT) pathway. In major depression, activation of the KYN pathway may deplete 5-HT. In the present study we investigated the influence of various risk factors for depression, such as ageing, social isolation and psychological stress, on TRP metabolism. Male ICR mice (postnatal day, PND, 21) were divided into two housing conditions, isolation and group housing, reared for 4 weeks (young adult) or 5 months (adult) and exposed to novelty stress. We measured TRP, KYN and 5-HT contents in the prefrontal cortex, hippocampus, amygdala and dorsal raphe nuclei to investigate the balance between the KYN and 5-HT pathways. Ageing decreased TRP and KYN and increased 5-HT. Thus, ageing shifted the balance to the latter. In the younger group, social isolation decreased TRP and KYN and increased the 5-HT/TRP ratio, whereas novelty stress increased TRP and KYN and decreased the 5-HT/TRP ratio. Thus, social isolation shifted the balance to the latter, whereas novelty stress shifted it to the former. In the older group, these effects were restricted to specific brain regions. Ageing and social isolation counteracted novelty stress effects on TRP metabolism.     

Confirming,Validating, and Norming the Factor Structure of Systemic Therapy Inventory of Change Initial and Intersession

Progress or feedback research tracks and feeds back client progress data throughout the course of psychotherapy. In the effort to empirically ground psychotherapeutic practice, feedback research is both a complement and alternative to empirically supported manualized treatments. Evidence suggests that tracking and feeding back progress data with individual or nonsystemic feedback systems improves outcomes in individual and couple therapy. The research reported in this article pertains to the STIC^® (Systemic Therapy Inventory of Change)—the first client‐report feedback system designed to empirically assess and track change within client systems from multisystemic and multidimensional perspectives in individual, couple, and family therapy. Clients complete the STIC Initial before the first session and the shorter STIC Intersession before every subsequent session. This study tested and its results supported the hypothesized factor structure of the six scales that comprise both STIC forms in a clinical outpatient sample and in a normal, random representative sample of the U.S. population. This study also tested the STIC's concurrent validity and found that its 6 scales and 40 of its 41 subscales differentiated the clinical and normal samples. Lastly, the study derived clinical cut‐offs for each scale and subscale to determine whether and how much a client's score falls in the normal or clinical range. Beyond supporting the factorial and concurrent validity of both STIC forms, this research supported the reliabilities of the six scales (Omega_hierarchical) as well as the reliabilities of most subscales (alpha and rate–rerate). This article delineates clinical implications and directions for future research.     

Self‐criticism and self‐reassurance as mediators between mental health attitudes and symptoms: Attitudes toward mental health problems in Japanese workers

Japanese workers suffer high rates of mental health symptoms, recognised recently by the Japanese government, which has enacted workplace well‐being initiatives. One reason for poor mental health concerns negative attitudes about mental health problems such as shame, which may be mediated by self‐reassurance and self‐criticism. This study aimed to evaluate shame‐based attitudes toward mental health problems and explore the relationship between mental health attitudes, self‐criticism, self‐reassurance, and mental health symptoms. Japanese workers (n = 131) completed three measures: attitudes toward mental health problems, mental health symptoms, and self‐criticism/reassurance. A high proportion of workers reported negative attitudes about mental health problems. There were strong relationships between mental health attitudes, mental health symptoms, self‐criticism, and self‐reassurance. Path analyses revealed that the total and indirect effects (through self‐criticism and self‐reassurance) of mental health attitudes on mental health were larger than the direct effect alone. Hated‐self and family reflected shame were identified as predictors for mental health symptoms. The findings suggest the importance of self‐criticism and self‐reassurance in mental health and mental health attitudes. Implications for help‐seeking behaviours also are discussed. Interventions aimed at reducing self‐criticism and enhancing self‐reassurance are recommended to improve mental health attitudes and increase help‐seeking in Japanese workers.     

Enhanced recovery of NK cell activity in mice under restraint stress by the administration of a biological response modifier derived from the mycelia of the basidiomycete Tricholoma matsutake

Some types of stressor act on the immune system via the network comprising the endocrine-immune-nervous systems, and are reportedly responsible for the onset of diseases as well as giving impetus to their advance. It is important for the maintenance and promotion of health to cope with stress-induced changes in immunocompetence. Therefore, we studied the effects of administration of a novel biological response modifier (CM6271) derived from the mycelia of the basidiomycete Tricholoma matsutake on the NK cell activity in mice under restraint stress, in order to evaluate its potential to modulate immune responsiveness in stress-loaded individuals. (1) When C57BL/6 mice were restrained in 50-ml tubes for more than 6 h, splenic NK cell activity decreased significantly, but recovered gradually after the mice were released. The extent of the reduction of activity and the degree of recovery depended on the duration of the restraint. (2) The oral administration of CM6271 caused a significant acceleration of the recovery of the activity. This effect was dependent on the timing of administration and the dose given. (3) The administration of CM6271 had no clear effect on the blood levels of ACTH, corticosterone or lipid peroxide levels in the liver. These findings suggest that CM6271 promotes recovery from the decrease in NK cell activity induced by restraint stress.
