The spacing effect in 4- to 9-year-old children

Experiment 1 of the current research failed to replicate Toppino and Di George’s (1984) finding that older children but not preschoolers showed a spacing effect. Instead, we obtained the spacing effect in all the age groups tested (preschool, kindergarten, first-grade, and third-grade children). The effect was demonstrated with two types of material, words and pictures. Experiment 2 focused on the role that very brief spacings, with no intervening items between repetitions, play in later retention. Age groups and materials were the same as in Experiment 1. Four different levels of spacing were included (0-, 1.1-,2.5-, and 5-sec intervals). The spacing effect was again obtained for all age groups with both words and pictures. The results of both experiments suggest that the spacing effect does not emerge with development.     

Writing brains: tracing the psyche with the graphical method

At the end of the 19th century, the graphic method kindled attempts to use it for investigating psychic processes. In Germany, Hans Berger took up this line of research, later to become the pioneer of electroencephalography (EEG). This trajectory of Berger's work is analyzed as an "enabling constraint" guiding him toward the EEG at a time when nobody else was pursuing this line of research and also causing serious methodological problems. In the epistemological perspective of this analysis, many of his problems extend beyond the local context of his work and point toward ambiguities surrounding the project to trace the psyche with the graphic method. From the mid-1930s, the EEG inspired ongoing attempts to decipher the specific meanings of these recordings, and large ensembles of machinery were mobilized, molding concepts of the psyche according to the results and the specifications of the graphic method.     

Anchors distort estimates of expected duration

This research explored the effect of presenting participants an anchor, which is a salient standard of comparison, before asking them to estimate the amount of time they believe they will need to complete a task (expected duration estimation). Such anchors can be assumed to be common in real-life situations, e.g., duration suggestions made by work colleagues. Participants were 32 students (M age = 23.1 yr., SD = 3.2; 28 women) who received course credit for participating. In the presence or absence of one of two anchors they had to estimate how much time they would need to work on a catalogue task. Actual time needed for the task was also measured. As predicted, analysis showed that estimates of expected duration were distorted in the direction of the anchors, i.e., estimations were assimilated into the presented anchor value. The implications for time management are discussed.     

Cross-Cultural Differences in the Attitude Toward Applicants’ Faking in Job Interviews

Purpose

This study questions whether applicants with different cultural backgrounds are equally prone to fake in job interviews, and thus systematically examines cross-cultural differences regarding the attitude toward applicants’ faking (an important antecedent of faking and a gateway for cultural influences) on a large scale.

Design/Methodology/Approach

Using an online survey, employees’ (N = 3252) attitudes toward faking were collected in 31 countries. Cultural data were obtained from the Global Leadership and Organizational Behavior Effectiveness project (GLOBE).

Findings

Attitude toward faking can be differentiated into two correlated forms (severe/mild faking). On the country level, attitudes toward faking correlate in the expected manner with four of GLOBE’s nine cultural dimensions: uncertainty avoidance, power distance, in-group collectivism, and gender egalitarianism. Furthermore, humane orientation correlates positively with attitude toward severe faking.

Implications

For international personnel selection research and practice, an awareness of whether and why there are cross-cultural differences in applicants’ faking behavior is of utmost importance. Our study urges practitioners to be conscious that applicants from different cultures may enter selection situations with different mindsets, and offers several practical implications for international personnel selection.

Originality/Value

Cross-cultural research has been expected to answer questions of whether applicants with different cultural backgrounds fake to the same extent during personnel selection. This study examines and explains cross-cultural differences in applicants’ faking in job interviews with a comprehensive sample and within a coherent theoretical framework.

     

Dissociable stages of problem solving (II): first evidence for process-contingent temporal order of activation in dorsolateral prefrontal cortex

In a companion study, eye-movement analyses in the Tower of London task (TOL) revealed independent indicators of functionally separable cognitive processes during problem solving, with processes of building up an internal representation of the problem preceding actual planning processes. These results imply that processes of internalization and planning should also be distinguishable in time and space with respect to concomitant brain activation patterns. To investigate this possibility, here we conducted analyses of fMRI data for left and right dorsolateral prefrontal cortex (dlPFC) during problem solving in the TOL task by accounting for the trial-by-trial variability of onsets and durations of the different cognitive processing stages. Comparisons between stimulus-locked and response-locked modeling approaches affirmed that activation in left dlPFC was elicited particularly during early processes of internalization, comprising the extraction of goal information and the generation of an internal problem representation, whereas activation in right dlPFC was predominantly attributable to later processes of mental transformations on this representation, that is planning proper. Thus, present data corroborate the proposal that often observed bilateral dlPFC activation patterns during complex cognitive tasks such as problem solving may reflect functionally and, to some extent, even temporally separable processes with opposing lateralizations.     

Dating Violence Prevention Programming: Directions for Future Interventions

Dating violence among college students is a widespread and destructive problem. The field of dating violence has seen a substantial rise in research over the past several years, which has improved our understanding of factors that increase risk for perpetration. Unfortunately, there has been less attention paid to dating violence prevention programming, and existing programs have been marred with methodological weaknesses and a lack of demonstrated effectiveness in reducing aggression. In hopes of sparking new research on dating violence prevention programs, the current review examines possible new avenues for dating violence prevention programming among college students. We discuss clinical interventions that have shown to be effective in reducing a number of problematic behaviors, including motivational interventions, dialectical behavior therapy, mindfulness, and bystander interventions, and how they could be applied to dating violence prevention. We also discuss methodological issues to consider when implementing dating violence prevention programs.
