Contextual Responses to Affirmative and/or Reversed-Worded Items

Psychometrika - This paper presents a systematic investigation of how affirmative and polar-opposite items presented either jointly or separately affect yea-saying tendencies. We measure these...     

The Swedes and the Paranormal

The hypothesis that Church and Science have lost some of their former standing in Sweden and made way for deviant beliefs is examined in two empirical studies which show a widespread belief in paranormal phenomena. The paper also discusses how believers in the paranormal relate to institutionalised religious beliefs and how problematic the interpretation of religious self-assessment items are.

Multilevel Multivariate Meta-analysis with Application to Choice Overload

We introduce multilevel multivariate meta-analysis methodology designed to account for the complexity of contemporary psychological research data. Our methodology directly models the observations from a set of studies in a manner that accounts for the variation and covariation induced by the facts that observations differ in their dependent measures and moderators and are nested within, for example, papers, studies, groups of subjects, and study conditions. Our methodology is motivated by data from papers and studies of the choice overload hypothesis. It more fully accounts for the complexity of choice overload data relative to two prior meta-analyses and thus provides richer insight. In particular, it shows that choice overload varies substantially as a function of the six dependent measures and four moderators examined in the domain and that there are potentially interesting and theoretically important interactions among them. It also shows that the various dependent measures have differing levels of variation and that levels up to and including the highest (i.e., the fifth, or paper, level) are necessary to capture the variation and covariation induced by the nesting structure. Our results have substantial implications for future studies of choice overload.     

Individually tailored internet-based cognitive behaviour therapy for older adults with anxiety and depression: a randomised controlled trial

Mixed anxiety and depression is common among older adults. The aim of the study was to compare the effects of an eight-week-long tailored internet-supported cognitive behaviour therapy (ICBT) programme and to compare against the provision of weekly general support. A second aim was to investigate if pre-treatment cognitive flexibility and self-reported cognitive problems would predict outcome. We included 66 older adults (aged over 60 years) with mixed anxiety/depression following media recruitment and randomised them into treatment and control groups. We also included a one-year follow-up. As a measure of executive function, we used the Wisconsin Card Sorting Test (perseverative errors) and the Cognitive Failures Questionnaire during the pre-treatment phase. Results showed a moderate between-group effect on the main outcome measure, the Beck Anxiety Inventory (BAI) (d= .50), favouring the treatment group. Nearly half (45.5%) of that group were classified as responders. One person (3%) in the treatment group deteriorated. There were significant correlations between perseverative errors and outcome (on the BAI r = ?.45), but not among self-reported cognitive function. We conclude that guided, tailored ICBT may be effective for some older adults and that the role of cognitive function needs to be investigated further.     

Religious versus Conventional Internet-based Cognitive Behavioral Therapy for Depression

The accessibility and efficacy of two Internet-supported interventions for depression: conventional cognitive behavioral therapy (C-CBT) and religious CBT (R-CBT) were investigated. Depressed participants (N = 79) were randomly assigned to either active treatment or wait-listed control group. Self-report measures of depression, anxiety, and life quality were collected before, immediately after, and 6 months after the intervention. Significant differences among the three conditions emerged at post-intervention with medium to large effect sizes (Cohen’s d between 0.45 and 1.89), but no differences between the R-CBT and C-CBT were found. However, the addition of religious components to CBT contributed to the initial treatment appeal for religious participants, thus increasing the treatment accessibility.     

The changing psychology of culture in German‐speaking countries: A Google Ngram study

This article provides evidence for the long‐term affiliation between ecological and cultural changes in German‐speaking countries, based on the assumptions derived from social change and human development theory. Based on this theory, the increase in urbanisation, as a measure of ecological change, is associated with significant cultural changes of psychology. Whereas urbanisation is linked to greater individualistic values and materialistic attitudes, rural environments are strongly associated with collectivistic values like allegiance, prevalence of religion, and feelings of belonging and benevolence. Due to an increase in the German urbanisation rate over time, our study investigates whether Germany and the German‐speaking countries around show the presumed changes in psychology. By using Google Books Ngram Viewer, we find that word frequencies, signifying individualistic (collectivistic) values, are positively (negatively) related to the urbanisation rate of Germany. Our results indicate that predictions about implications of an urbanising population for the psychology of culture hold true, supporting international universality of the social change and human development theory. Furthermore, we provide evidence for a predicted reversal for the time during and after World War II, reflecting Nazi propaganda and influence.     

Achievement of specificational information usage with true and false feedback in learning a visual relative-mass discrimination task

Participants' usage of informational variables in learning visual relative-mass discrimination in collisions was tracked by means of PROBIT correlations. Four groups received feedback that was true or accorded with either of three nonspecificational cue variables. A majority in each group adopted the feedback, but several participants defied the false feedback. Unlike in previous research, the fit to data of the relative-mass invariant could not be bettered by post hoc linear combinations of the cues. Discriminability was lower in the use of the invariant. Analytic complexity was rejected as an explanation for discriminability differences. A "smart mechanism" for pickup of the relative-mass invariant was developed as an extension of G. Johansson's (1950/1994) vector model.
