Relating momentary affect to the five factor model of personality: A Japanese case1

Abstract: This article shows that fundamental aspects of the structure of momentary affect are similar in Japanese and Canadian societies. We developed questionnaire scales in Japanese in four different formats for assessing self-reported momentary affect. Scales can be scored for dimensions defined by Feldman Barrett and Russell (1998 ), Thayer (1996 ), Larsen and Diener (1992 ), and Watson and Tellegen (1985 ). We administered these newly developed affect scales and NEO five-factor inventory ( Costa & McCrae, 1992 ) to a sample of 450 Japanese respondents. The affect scales were found to be psychometrically sound and to be interrelated, as found with English-speaking Canadians. Dimensions could be integrated into a two-dimensional affective space. Personality correlated with momentary affect, though not in the same pattern as found in Canada.     

Choice Between Two Discrimination Tasks in Chimpanzees (Pan troglodytes)

The purpose of the present study was to investigate the effects of cognitive effort on a chimpanzee's choice between discrimination tasks. The tasks were of the matching-to-sample type. In Experiment 1, the chimpanzee was required to choose between a task providing a high reinforcement rate with high cognitive effort and a task providing a low reinforcement rate with low cognitive effort. Her choice depended on the reinforcement rate more than the cognitive effort. Experiments 2, 3, and 4 examined whether the kind of cognitive effort influenced the chimpanzee's choice. Experiment 2 manipulated the sample-choice relationship, so-called symmetry in the matching-to-sample tasks. Experiment 3 manipulated the number of comparison stimuli. Experiment 4 manipulated the delay interval between the sample and the comparison stimuli. In Experiments 2 and 3, the effects of the cognitive effort were confounded with those of the reinforcement rates. However, in one condition of Experiment 4, the chimpanzee preferred the simultaneous task to the delayed task, despite the lack of a significant difference in reinforcement rates between the two tasks. The present study demonstrated that the chimpanzee's choice of discrimination task depended on the cognitive effort involved, in addition to the reinforcement rate.     

Reactivation-dependent changes in memory states in the terrestrial slug Limax flavus

The change in memory state in the terrestrial slug Limax flavus was studied using cooling-induced retrograde amnesia. Slugs were first conditioned to avoid carrot odor and then a second conditioning procedure was applied 1, 3, 6, or 7 days after the first conditioning trial. Cooling the slugs to approximately 1 degrees C on day 7 immediately after the presentation of the odor used in the conditioning resulted in retrograde amnesia in the slugs that were subject to a second conditioning on day 6 or 7, but not in slugs that were subject to a second conditioning on day 1 or 3. Next, second-order conditioning was used as the second conditioning procedure to distinguish the memory acquired in the first conditioning from that acquired in the second conditioning and similar results were obtained. These results suggest that the reactivation of memory altered the memory state from a cooling-insensitive state to a cooling-sensitive one. A possible model for memory states is discussed.     

Suicide prevention in the Pacific War (WW II).

During the war against Japan, there were two facets of an American program to prevent suicide among the Japanese. One was a research component in the Foreign Morale Analysis Division (FMAD), a subunit of the Office of War Information. The principal FMAD figure who did most of the research on Japanese suicide and ways to prevent suicide among the Japanese military was the anthropologist Ruth Benedict, assisted by her Japanese-American aide Robert Hashima. The second facet was the suicide prevention program itself, which was put into effect toward the end of the war in the battles of Saipan and Okinawa. This program of action was undertaken by American GIs. These unheralded activities in suicide prevention merit a place in the annals of suicide prevention programs.     

On the locus of redundancy effects in a letter-detection task

It takes longer to detect a target if it is the initial letter of a nonredundant letter string such as BNHTW than if it is the initial letter of a redundant letter string such as BBBBB (Johnson, 1986b; Johnson & Blum, 1988). The results of the present study reveal that the redundancy effect also occurs for mixed-case letters strings (e.g., BbbBb) and digit strings (e.g., 22222). In addition, these results suggest that the cause of the redundancy effect is not related to the visual properties of the noninitial letters per se but is instead related to the presence of the target in noninitial positions. Together, these results rule out a number of hypotheses about the cause of the redundancy effect and suggest that the locus of this effect is in processes involved in response selection and/or the read-out of information from the perceptual system.     

Measuring individual differences in sensitivities to basic emotions in faces

The assessment of individual differences in facial expression recognition is normally required to address two major issues: (1) high agreement level (ceiling effect) and (2) differential difficulty levels across emotions. We propose a new assessment method designed to quantify individual differences in the recognition of the six basic emotions, 'sensitivities to basic emotions in faces.' We attempted to address the two major assessment issues by using morphing techniques and item response theory (IRT). We used morphing to create intermediate, mixed facial expression stimuli with various levels of recognition difficulty. Applying IRT enabled us to estimate the individual latent trait levels underlying the recognition of respective emotions (sensitivity scores), unbiased by stimulus properties that constitute difficulty. In a series of two experiments we demonstrated that the sensitivity scores successfully addressed the two major assessment issues and their concomitant individual variability. Intriguingly, correlational analyses of the sensitivity scores to different emotions produced orthogonality between happy and non-happy emotion recognition. To our knowledge, this is the first report of the independence of happiness recognition, unaffected by stimulus difficulty.     

Relationship between two aspects of perfectionism and obsessive-compulsive symptoms

In this study was investigated the relationship between two aspects of perfectionism (Concern over Mistakes and Personal Standards) and obsessive-compulsive symptoms. College students (57 men and 193 women: M age = 19.5 yr., SD = 1.9) majoring in psychology were from introductory psychology classes and a psychological assessment practice class. They completed the Padua Inventory, which assesses obsessive-compulsive symptoms, and the subscales of Concern over Mistakes and Personal Standards of the Frost Multidimensional Perfectionism Scale, which assess the tendency to be concerned about making mistakes and the tendency to set excessively high standards, respectively. Multiple regression analysis indicated that only the Concern over Mistakes scores predicted significantly all Padua Inventory subscale scores. Perhaps only being concerned over making mistakes may be associated with obsessive-compulsive symptoms. The tendency to set high standards was not strongly correlated with obsessive-compulsive symptoms. Further, the relationship between setting high standards and having obsessive-compulsive symptoms reported in previous studies may be spurious. Further work is required to untangle these associations.     

Coping responses of Asian, Black, and Latino/Latina New York City residents following the September 11, 2001 terrorist attacks against the United States

This study examined mechanisms for coping with adversity in a sample of 24 Asian, Black, and Latino/Latina residents of New York City following the September 11, 2001 World Trade Center (WTC) terrorist attacks. Using consensual qualitative research methodology (C. E. Hill, B. J. Thompson, & E. N. Williams, 1997), the authors identified 7 broad coping domains used by the participants: (a) sought additional information about the WTC tragedy, (b) expressed a range of emotions, (c) sought or gave support, (d) engaged in religious or spiritual activities, (e) avoidance, (f) forbearance, and (g) used indigenous healing techniques. Although there were similarities across racial or cultural groups and genders with regard to the coping responses used, there also were unique coping strategies by racial or cultural background and gender.     

Ayahuasca in Western society and the metacognitive counselling approach

Ayahuasca is a hallucinogenic plant used throughout South America for religious, cultural and healing ceremonies. Previous studies have analysed it as a therapy method from either the microperspective, such as physiological and psychological effects of substance use, or the macroperspective, such as legal issues or cultural appropriation of ayahuasca by Westerners. There is a need to combine those two aspects to fully understand the effects of ayahuasca for therapists and clients in Western communities. By utilising an autoethnographic instrumental case study, we discuss the possible risk of ayahuasca gaining popularity in Western societies without an understanding of how the social context plays a tremendous part in healing using this method. We also discuss the risk of intrapsychic experiences brought about by ayahuasca that may deter individuals from seeking appropriate treatment. It is not our intention to present ayahuasca as an illegitimate or invalid method of healing; rather, we emphasise the importance of integrating micro- and macroperspectives in psychotherapy practice. We suggest that the metacognitive counselling approach be taken by both clients and therapists when adopting indigenous methods of therapy which may add a significantly positive effect. Although we hope this study offers realistic and lived experiences to generate pragmatic solutions for therapists and clients, we recognise that it is necessary to collect data from a larger number of both clients and therapists to better support our suggestion of the metacognitive counselling approach.     

Geographical profiling incorporating neighbourhood-level factors using spatial interaction modelling

The aim of this study was to examine the applicability of methods that use spatial interaction modelling to predict the most probable area for an offender's residence. Tokyo, which is the capital of Japan and is divided into 1507 square-kilometre zones, was selected as the study area. We analysed 4316 criminal trips to commit residential burglaries by 1089 offenders who lived in Tokyo. The following neighbourhood-level factors, and a distance-decay effect between zones, were incorporated into the proposed model: the size of the residential population aged 15–59 years in origin zones, the numbers of households living in detached houses, newcomers, the number of police facilities in destination zones, and the spatial structures of the criminal trips. Search areas calculated by the proposed model were smaller than previous models, suggesting that neighbourhood-level factors are important for predicting the location of an offender's residence.
