Use of the Jackknife Statistic to Evaluate Result Replicability

Result replicability has often been confused with significance testing because of a misinformed view that statistical significance evaluates result importance and result replicability. Several alternatives, of which the jackknife statistic is one, provide researchers with the tools for estimating result replicability. In the present study, an available data set from A. L. Edwards (1985, p. 57) is used to illustrate the use of the jackknife statistic to assess the replicability of multiple regression results in a concrete fashion. The jackknifed coefficients are computed to assess the stability of beta weights and the multiple R ² value. Confidence intervals and t statistics are also calculated to facilitate the interpretation of these jackknifed coefficients.

Similarity and social interaction: when similarity fosters implicit behavior toward a stranger

People interact more readily with someone whom they think they have something in common with. At a pedestrian crossing, confederates asked participants for the time and, in one condition, said she/he had the same watch as the participant. The amount of time that participants lingered near a confederate was used as the dependent variable. Participants in the similarity condition spent significantly more time near the confederate than when no similarity was manipulated. The results showed that similarity fosters implicit behavior, adding to the growing body of data on the positive effects of similarity and its role in social interaction.     

Neighborhood Protective Effects on Depression in Latinos

Neighborhood social ecologies may have protective effects on depression in Latinos, after adjusting for demographic risk factors, such as nativity and length of stay in the US. This study examines the effects of neighborhood collective efficacy and linguistic isolation on depression in a heterogeneous urban Latino population from 1,468 adult respondents in Los Angeles County. We used multilevel models to analyze how major depression is associated with socioeconomic background, length of stay in the U.S., neighborhood collective efficacy and linguistic isolation among Latinos. A significant cross-level interaction effect was found between collective efficacy and foreign-born Latinos who resided in the US ≥ 15 years. We report cross-level interaction effects between linguistic isolation and nativity for U.S.-born and nativity and duration of residence for foreign-born Latinos who had lived in the U.S. at least 15 years. The moderating effects reported in this study suggest that the benefits of neighborhood collective efficacy and linguistic isolation vary by Latino subgroup and are conceptually discrete forms of social capital and offer insights for community based interventions.     

Authoritarian Parenting Style in Asian Societies: A Cluster- Analytic Investigation*

While the beneficial effects of authoritative parenting style have consistently been demonstrated for Caucasian samples, these effects have not always been found for Asians. It appears that adolescents who perceived their parents’ style of parenting as authoritarian are not one homogeneous group. Cluster analyses performed for adolescents’ perceived mothers’ and fathers’ authoritarian parenting style using adolescents’ self-report scores on personal adjustment and social variables as the clustering variables found similar two-cluster solutions (maladjusted and well-adjusted). External validation evidence revealed that adolescents in the maladjusted cluster had poorer attitudes towards school and teachers compared to adolescents in the well-adjusted cluster for both samples. These findings suggest that authoritarian parenting style could possibly have a different cultural meaning for Asians. ^*The authors would like to thank staff from Tampines Family Service Center for their assistance with data collection.

Understanding Conspiracy Theories

Scholarly efforts to understand conspiracy theories have grown significantly in recent years, and there is now a broad and interdisciplinary literature. In reviewing this body of work, we ask three specific questions. First, what factors are associated with conspiracy beliefs? Our review of the literature shows that conspiracy beliefs result from a range of psychological, political, and social factors. Next, how are conspiracy theories communicated? Here, we explain how conspiracy theories are shared among individuals and spread through traditional and social media platforms. Next, what are the societal risks and rewards associated with conspiracy theories? By focusing on politics and science, we argue that conspiracy theories do more harm than good. We conclude by suggesting several promising avenues for future research.     

Factors influencing adolescents engagement in risky Internet behavior.

The present study used data from the SAFT (Safety, Awareness, Facts and Tools) Singapore survey, a national survey of 1,124 youths aged 12-17, to explore the issue of risk on the Internet. We investigated factors that influence adolescents' engagement in risky Internet behavior, in particular, meeting face-to-face someone they first encountered online. The adolescents ranged from ages 12 to 17, with a mean of 14.32 (SD = 1.37); 49.6% of the adolescents were girls. The study utilized a 93-item survey that was part of the SAFT Project. Results indicated that 16% of adolescent Internet users in Singapore have had a face-to-face meeting with someone first encountered online. The following factors were found to be predictors of adolescents engagement in such face-to-face meetings: age, frequency of Internet use, frequency of chatting and gaming behavior, parental rules, type of personal information given out, amount of inappropriate messages received, whether inappropriate websites have been visited, and type of internet advice heard. Implications of the results are discussed.     

Remembering as Necessary for Forgiving

As Japan marks the 75th anniversary of World War II in 2020, Prime Minister Shinzo Abe did not offer a fresh apology and maintained that future generations should not have to keep apologizing for past mistakes. This paper uses the unresolved war issue of the military comfort women system as a context to discuss what it means for political apologies to be more than mere political gestures founded on political interests and discusses what it takes to facilitate forgiveness. It will examine the features of a repentant wrongdoer who deserves forgiveness based on how one relates to one’s past wrongdoing in order to distinguish political apologies that are genuine from those that are mere gestures aimed at hasty reconciliation. This will be discussed through the works of Jacques Derrida and Vladimir Jankélévitch. Next, through Jankélévitch’s and Paul Ricoeur’s ideas of forgiveness, it will be discussed how matters of justice and forgiveness should be understood as well as how the history of past wrongs and injustice is necessary for a genuine apology and makes forgiveness possible. It is also a moral responsibility for both perpetrators and victims to remember history in order to achieve personal forgiveness as well as begin social and political reconciliation.

     

The relationship between expertise and evaluative extremity: the moderating role of experts' task characteristics

Past research has yielded contradictory results with regard to the relationship between expertise and evaluative extremity. The authors suggest that this apparent contradiction is due to the task characteristics of the expert activity. The primary task of certain experts is to formulate overall (configural) judgments and to generate clear, unambiguous answers. These experts tend to give relatively extreme evaluations. Other experts generally communicate the implications of the different choice alternatives and explain featural aspects of the stimuli. These experts are characterized by relatively moderate evaluations. The research reported in this article shows that experts whose expert activity involves configural judgments tend to make more extreme evaluations than experts who generally provide others with featural explanations. It also demonstrates that experts' task characteristics affect the way they store stimulus-relevant attributes in memory.     

To what extent does typicality boost semantic priming effects between members of their categories?

Atypical items of their semantic category yield more generalisation than their typical members when relearning in connectionist networks (Plaut, D. C. (1996). Relearning after damage in connectionist networks: toward a theory of rehabilitation. Brain and Language, 52(1), 25–82) and in empirical studies (Kiran, S., & Thompson, C. K. (2003). The role of semantic complexity in treatment of naming deficits: Training semantic categories in fluent aphasia by controlling exemplar typicality. Journal of Speech, Language, and Hearing Research, 46(4), 773–787). It seems therefore that atypical words provide more information about the overall structure of the semantic category due to their specific and shared features. In this view, atypical primes could strongly facilitate the processing of targets compared to typical primes, because typical primes contain little information about the variation between members within a category. In contrast, three semantic priming experiments in visual word recognition showed an advantage with the typical context, but not with the atypical one. These findings were observed in a variety of tasks, including lexical decision, categorisation and semantic judgment. Our results do not support the findings about generalisation in relearning and suggest that typicality effects in semantic priming mostly come from the activation of representative features of categories.
