Multiple comparisons in two-factor testing of psychophysical thresholds by the delta test method

We propose an algorithm of multiple comparisons in two-factor testing of psychophysical thresholds. We use logistic regression combined with guessing rate and adopt the step-down procedure with Ryan–Einot–Gabriel–Welsch (REGW) significance levels for multiple test. We test hypotheses of main effects and interaction in two-factor problem by using the delta test statistics.

Changing Italian Families in the Era of Fertility Decline

Abstract:  Over the past few decades, in examining the social causes of low fertility in advanced societies, sociologists and demographers have shown increasing interest in southern European countries. Italy has been recognized as one of these countries plagued by lowest-low fertility. In general, the literature has depicted certain characteristics of Italian families as possible causes of fertility decline. This article examines the situation of contemporary Italian families and intergenerational relationships from a sociological point of view, particularly in comparison with Japanese families. It has sometimes been argued that strong familism characterizes Italian families and society. According to this view, one of the causes of fertility decline in Italy is the continuity of strong families. Empirical data suggest, however, that this familism perspective cannot explain the differences in family patterns observed among Italian regions. In addition, a comparison between Italy and Japan with respect to intergenerational relationships suggests that there are substantial differences between the two countries. It is suggested that a further exploration of the various aspects of social contexts is needed in order to clarify what is distinctive about contemporary Italian families.     

Young People’s Reactions Change Elderly People’s Generativity and Narratives: The Effects of Intergenerational Interaction on the Elderly

The aim of this study was to investigate the effect of the young listener’s reaction on the development of generativity and narratives of elderly people. Thirty-four males between the ages of 60 and 82 participated in this experiment in which the listener generations (young/elderly) and listener reactions (empathic/neutral) were controlled. The participants shared and taught their wisdom gained from their past experiences through narratives. Results showed that many elderly people spoke about “lessons from experiences of failure” when there was an empathic reaction from young people, and such narratives were promoted by an increase of generativity. These results suggested the impact of the younger people’s reaction on the elderly people’s psychological development and behavior.     

Intergenerational interaction between old and young in creative task

By comparing intergenerational to same-generation interactions in creative activities, we aimed to reveal characteristic behaviors of older and younger adults in intergenerational interactions using a wooden block task. Four categories (“Proposal request”, “New proposal”, “Reactions to proposal”, “Assessments of partner’s behavior”) were extracted from conversations during task performance. In intergenerational groups, the ratio of utterances of “Proposal request” (encouraging a new proposal to partner) were higher than in same-generation groups for older adults. In intergenerational groups, older people assumed the role of encouraging younger people to suggest new ideas, and older people’s such empathic behaviors might provoke lively arguments.
