Research and publication trends in experimental social psychology: 1971–1980—a thematic analysis of the journal of experimental social psychology,the european journal of social psychology,and the zeifschrift für soziaipsychologie

The present study was designed to map out the area of research in experimental social psychology during the past decade. First of all, we found a broad range of topics that can be grouped info 21 general content domains. Theories in Social Psychology, Group Processes and Social Interaction, Social Judgement, Personality Variables and Specific Social Behaviour as well as Attitudes were the jive most widely researched fields of study. During the ten-year period 1971–1980 Attribution Theory showed a significant increase in the number of articles published. Cooperation and Conflict as well as Risky-Ship are lines of research which have nearly been abandoned. Finally, in rigorous experimental social psychology the analysis of Social Problems is evidently underrepresented. But a survey of the literature on Social Problems in the Psychological Abstracts from 1971 to 1980 revealed that social psychologists are currently serving both theoretical and practical ends.

I wish it were true: Confessions of a secret deductivist

The criticisms by S. V. Paunonen and D. N. Jackson (1985, Journal of Research in Personality, 19, 331–342) are examined in detail. Despite the best of intentions, the author remains unconvinced.

Working with Research Integrity—Guidance for Research Performing Organisations: The Bonn PRINTEGER Statement

This document presents the Bonn PRINTEGER Consensus Statement: Working with Research Integrity—Guidance for research performing organisations. The aim of the statement is to complement existing instruments by focusing specifically on institutional responsibilities for strengthening integrity. It takes into account the daily challenges and organisational contexts of most researchers. The statement intends to make research integrity challenges recognisable from the work-floor perspective, providing concrete advice on organisational measures to strengthen integrity. The statement, which was concluded February 7th 2018, provides guidance on the following key issues:

1. § 1.
   Providing information about research integrity
    
2. § 2.
   Providing education, training and mentoring
    
3. § 3.
   Strengthening a research integrity culture
    
4. § 4.
   Facilitating open dialogue
    
5. § 5.
   Wise incentive management
    
6. § 6.
   Implementing quality assurance procedures
    
7. § 7.
   Improving the work environment and work satisfaction
    
8. § 8.
   Increasing transparency of misconduct cases
    
9. § 9.
   Opening up research
    
10. § 10.
    Implementing safe and effective whistle-blowing channels
     
11. § 11.
    Protecting the alleged perpetrators
     
12. § 12.
    Establishing a research integrity committee and appointing an ombudsperson
     
13. § 13.
    Making explicit the applicable standards for research integrity
     

     

Biases in multilevel analyses caused by cluster-specific fixed-effects imputation

When datasets are affected by nonresponse, imputation of the missing values is a viable solution. However, most imputation routines implemented in commonly used statistical software packages do not accommodate multilevel models that are popular in education research and other settings involving clustering of units. A common strategy to take the hierarchical structure of the data into account is to include cluster-specific fixed effects in the imputation model. Still, this ad hoc approach has never been compared analytically to the congenial multilevel imputation in a random slopes setting. In this paper, we evaluate the impact of the cluster-specific fixed-effects imputation model on multilevel inference. We show analytically that the cluster-specific fixed-effects imputation strategy will generally bias inferences obtained from random coefficient models. The bias of random-effects variances and global fixed-effects confidence intervals depends on the cluster size, the relation of within- and between-cluster variance, and the missing data mechanism. We illustrate the negative implications of cluster-specific fixed-effects imputation using simulation studies and an application based on data from the National Educational Panel Study (NEPS) in Germany.     

Simultaneous motor demands affect decision making under objective risk

Previous studies on factors influencing decision making focused on the effects of additional cognitive load, stress, psychological disorders, and the process of aging. The potential effects of simultaneously performing motor demands have been neglected, so far. However, previous motor / cognitive dual-task studies provide evidence for both negative as well as facilitating effects of simultaneously performing cognitive and motor tasks. The study at hand, aimed to investigate the effects of decision making under objective risk while performing additional motor demands. Seventy-two participants ranging from 18 to 30 years performed the Game of Dice Task either while sitting or while standing on one leg. Participants were asked to put similar effort on the decision task and the motor demand. The results revealed a significant main effect for “choice”, as well as a significant interaction of “choice”?×?“group”. Participants standing on one leg more frequently selected the most disadvantageous choice (one single number), whereas the “sitting group” most often selected the advantageous combination of four numbers. The findings are discussed under the aspects of executive functions, working memory, stress, somatic markers and the dual-process theory.
