Although multiple regression analysis is a frequently used method for multivariate analysis in psychological research, it has been used inappropriately or incorrectly in most studies. To resolve these problems effectively, we investigated and summarized the issues related to the use of multiple regression analysis found in papers published in The Japanese Journal of Psychology and discussed the issues in detail. We argue that researchers should not use multiple regression analysis for simplistic reasons, such as “because there are several independent variables” or “because some relationships between independent variables or between independent and control variables are supposed.” We further argue the importance of carefully considering whether the purpose of the study is to explain or to predict and what kind of causal relationships exist between variables.
The purpose of this study was to determine the causal relationship between Attachment Anxiety and Intimate Partner Violence (IPV). Several studies have showed that Attachment Anxiety increases IPV, but most of them were cross-sectional studies. Therefore, it is unclear whether Attachment Anxiety or IPV is an antecedent factor. Thus, we conducted two longitudinal studies of couples in romantic and marital relationships. In Study 1, a 6-month longitudinal survey was conducted on 392 young adults who were currently involved in a romantic relationship. In Study 2, a 2-year longitudinal survey was conducted on 412 married young and middle-aged adults. The results of structural equation modeling with a cross-lagged effect model showed that Attachment Anxiety predicted increases of later IPV in both types of relationships. These results are discussed in terms of adult attachment theory and IPV prevention.
Consultative behavior with spouses has been found to be effective in deterring telephone call–based fraud. This study aimed to identify the factors that enhance spousal counseling behavior during fraudulent phone call encounters. In December 2019, we conducted a questionnaire survey of 874 households each exclusively composed of an elderly marital couple (n = 1,748). The influence of the day-to-day marital relationship and trust in the spouse as a counselor on the intention to consult was examined using Actor-Partner Interdependence Model (APIM) analysis. The results showed that marital satisfaction had an indirect effect on intentions for consultative behavior, mediated by trust in both wives and husbands, and that marital satisfaction was defined by daily communication and positive problem-solving strategies. The results imply that efforts to communicate with spouses and to proactively solve problems increase marriage satisfaction and are also effective in promoting spousal counseling behavior.
In the midst of the current reproducibility crisis in psychology, pre-registration is considered a remedy to increase the reliability of psychological research. However, because pre-registration is an unconventional practice for most psychological researchers, they find it difficult to introduce pre-registration into their studies. To promote pre-registration, this article provides a detailed and practical step-by-step tutorial for beginners on pre-registration with Open Science Framework. Furthermore, a typical example what beginners might experience and ways to resolve such issues are provided as supplementary material. Finally, we discuss various issues related to pre-registration, such as transparent research, registered reports, preprints, and open science education. We hope that this article will contribute to the improvement of reproducible psychological science in Japan.
In modern society, gender equality is respected. However, the entanglement of gender relations remains a problem. In this study, we investigated the possibility that activation of thoughts about romantic love increases the salience of stereotypical gender role expectations, outside of consciousness, which causes a gender difference in the interpretation of ambiguous messages. In Study 1, in which participants carefully analyzed the scenario via conscious processing, and in Study 2, in which participants spontaneously responded to real-life situations via nonconscious processing, male participants in the romantic love priming conditions, compared to male participants in the control conditions, were more likely to respond to ambiguous messages with more positive emotions, and evaluated the message sender as being more attractive. However, such bias was not observed among female participants. Instead, they showed higher distrust toward ambiguous messages. These results show that even if the awareness of gender equality is raised, the activation of thoughts about romantic love makes stereotypical gender role expectations more salient, which leads to a difference in interpretation of ambiguous messages between males and females.
When comprehending (Japanese) null-subject sentences, people mentally simulate the linguistically depicted events without adopting a particular point-of-view (i.e., perspective) (Sato & Bergen, 2013). The present study examined whether a sense of agency (SoA), measured by the Sense of Agency Scale (Asai et al., 2009), predicts individual preferences in perspective adoption associated with the null-subject sentence comprehension. In the experiment with the sentence-picture verification task, participants read null-subject sentences and decided whether the depicted action had been mentioned in the preceding sentence. The results showed that participants with relatively stable SoA verified the action pictures (e.g., cutting an apple) significantly faster when the event was depicted from an observer’s perspective than when depicted from an agent’s perspective. On the other hand, participants with relatively unstable SoA showed no preference for the pictured perspectives. We concluded that the unstableness of SoA may result in ambiguous attribution of an action, reflected as the absence of a preferred perspective when comprehenders simulate the described event. The reason why individuals with stable SoA prefer an observer’s perspective was also discussed.
The present study aimed to clarify the cognitive and behavioral features of the process from the onset of stealing to the development of kleptomania. We also analyzed the differences between kleptomania and shoplifting for personal gain. Semi-structured interviews were conducted with 25 participants (15 patients with kleptomania, 4 shoplifters, and 6 with other addictions). An analysis based on a modified grounded theory approach (M-GTA) revealed 24 concepts and 5 categories. We identified four stages of the process of kleptomania. The stages were “first theft,” “increasing frequency of stealing,” “pathological stealing” where the act of stealing was more beneficial than the stolen goods, followed by “automatic stealing” whenever they steal automatically in their favorite stores. We identified “breaking dependence on stealing” as the fifth category. In contrast, shoplifters for personal gain did not move into “pathological stealing.” Thus, it is assumed that the development of kleptomania involves a series of processes from starting to steal to addiction, then, it is assumed to enter a dependent stage from the stage of “pathological stealing.”
The purpose of this study was to develop and examine the reliability and validity of a Japanese version of the Security in the Interparental Subsystem Scale (SIS), which measures children’s emotional security in the interparental relationship through self-assessment of their reactions to interparental conflict. We then examined the mediation model of emotional security between interparental conflict and children’s adjustment, as proposed in Emotional Security Theory (EST). A questionnaire study was conducted with 682 middle and high school students between 12 and 18 years of age (mean age = 14.80 years, SD = 1.50 years). The results of confirmatory factor analysis supported the theoretical model of EST, and the reliability and validity of the Japanese version of the SIS were demonstrated. Mediation analysis revealed mediated effects of emotional insecurity in the relationship between interparental conflict and children’s anxiety/depression and aggression. These results suggest that the theoretical model of EST can be effectively applied in Japan.
This research examined the influence of expectation on the association between emotional-support-seeking behavior and support evaluation in adolescence. In Study 1, 500 secondary-school students completed an anonymous survey, and five emotional-support expectations; acceptance-, reinterpretation-, justification-, optimism-, and distraction-expectation were detected for developing the emotional-support-expectation scale. The sample of Study 2 consisted of 1,007 secondary-school students who completed an anonymous survey that asked their stressor in the past month, support-seeking behaviors, emotional-support expectations, and support evaluation. Hierarchical multiple regression analysis indicated that frequent emotional-support-seeking behavior expects higher “perception of support from others” in the case of the reinterpretation expectation was high. Although emotional-support-seeking behavior showed direct influence only “perception of support from others” out of four support evaluations, reinterpretation expectation effected on “problem-solving” and “perception of support from others”, and also justification expectation effected on “confusion”. This result indicated that the effect of expectations on support evaluation. The necessity of longitudinal examination, consideration regarding the interaction between support seeker and supporter, and verification of adaptive change were discussed as future implications.
This study compared the intent to help in response to nonverbal and verbal stimuli that described people in need of help to clarify the conditions and generality of effects that promote the intent to help. Participants were randomly assigned to a help-imagining group, a no-help imagining group, or a control group. In Study 1, the participants evaluated verbal stimuli. In Study 2, they evaluated visual stimuli as illustrations developed for this study. The results of both studies indicated that the group imagining they were helping scored significantly higher for the intent to help than the other two groups, suggesting that improving imagination about helping increased helpful intentions, regardless of the stimuli type. Also, we found that different aspects of different stimuli affected the intent to help: the effect of evaluating the recipient’s emotional state on the intent to help was only observed for visual stimuli, and visual stimuli compared to verbal stimuli, were less likely to influence an individual’s imagination and past experience on the intent to help.
The “Tip of the Tongue” (TOT) is a well-known phenomenon in which one cannot recall the name of a familiar person or object but can recall related words. In the TOT state, cognitive processing activities based on relating information are frequently performed. Blinking is suppressed when waiting for information and when inputting or processing information, and instead occurs at the end of the processing phase. However, the relationship between blinking and the TOT state is not yet clear. In this study, we investigated how the timing of blink suppression and occurrence changes during the TOT state. We presented successive facial photographs of famous people interspersed with those of unknown persons. The participant’s task was to name the person during recall-stimulus after each of the photographs. The participant’s responses were classified as “Recognized,” “TOT,” and “Not recognized.” Our results indicated that blink suppression occurred most frequently while waiting for the recall-stimulus period in “Not recognized” responses, whereas suppression occurred least frequently in TOT responses. We conclude that blink suppression and occurrence is related to memory-system-access processing.
Conducting psychological experiments online has become popular in Japan and is useful for psychological research during the COVID-19 pandemic. Previous studies found that well-known psychological phenomena were successfully observed through online experiments. However, using recall tests, including a free recall test or a cued recall test, might be difficult in an online experiment. This is because the suggestion function, which is included in the Input Method Editor (IME), can aid recall when participants type their response. Recently, a plugin for online experiments, which might overcome this problem, was developed. However, it remains unclear if this technique is effective for psychological studies that use recall tests. Therefore, I examined whether false memory and retrieval-induced forgetting were replicated by recall tests in online experiments when the IME was bypassed by using the plugin. The results indicated that false recall and retrieval-induced forgetting were successfully observed. Given my results, online experiments using some types of recall tests can be conducted without the suggestion function.
Hand washing is one of the most effective measures to reduce the risk of transmitting infectious diseases. However, motivation for regular hand washing during the infectious phase of the SARS-CoV-2 infection remains unclear. We examined four possible reasons for practicing regular hand washing ̶ two involved the perceived effectiveness of this practice in reducing the risk of infection, and the other two involved other motivations. The results of our nationwide survey revealed that people conformed to other peopleʼs practice of washing hands and felt relief from their anxiety when washing their hands. The perceived effectiveness of personal risk reduction, however, showed little effect on the behavior, while motivations such as conformity and relief from anxiety successfully explained a large proportion of hand-washing behavior. Our findings suggest that policymakers responsible for public health should consider social motivations when implementing public strategies to combat the COVID-19 pandemic.
