Judging the animacy of words: The influence of typicality and age of acquisition in a semantic decision task

The age at which members of a semantic category are learned (age of acquisition), the typicality they demonstrate within their corresponding category, and the semantic domain to which they belong (living, non-living) are known to influence the speed and accuracy of lexical/semantic processing. So far, only a few studies have looked at the origin of age of acquisition and its interdependence with typicality and semantic domain within the same experimental design. Twenty adult participants performed an animacy decision task in which nouns were classified according to their semantic domain as being living or non-living. Response times were influenced by the independent main effects of each parameter: typicality, age of acquisition, semantic domain, and frequency. However, there were no interactions. The results are discussed with respect to recent models concerning the origin of age of acquisition effects.

D-optimal design for the Rasch counts model with multiple binary predictors

In this paper we derive optimal designs for the Rasch Poisson counts model and its extended version of the (generalized) negative binomial counts model incorporating several binary predictors for the difficulty parameter. To efficiently estimate the regression coefficients of the predictors, locally D-optimal designs are developed. After an introduction to the Rasch Poisson counts model and its extension, we will specify these models as particular generalized linear models. Based on this embedding, optimal designs for both models including several binary explanatory variables will be presented. Therefore, we will derive conditions on the effect sizes for certain designs to be locally D-optimal. Finally, it is pointed out that the results derived for the Rasch Poisson models can be applied for more general Poisson regression models which should receive more attention in future psychological research.

Economic Predictors of Differences in Interview Faking Between Countries: Economic Inequality Matters,Not the State of Economy

Many companies recruit employees from different parts of the globe, and faking behavior by potential employees is a ubiquitous phenomenon. It seems that applicants from some countries are more prone to faking compared to others, but the reasons for these differences are largely unexplored. This study relates country-level economic variables to faking behavior in hiring processes. In a cross-national study across 20 countries, participants (N = 3,839) reported their faking behavior in their last job interview. This study used the random response technique (RRT) to ensure participants’ anonymity and to foster honest answers regarding faking behavior. Results indicate that general economic indicators (gross domestic product per capita [GDP] and unemployment rate) show negligible correlations with faking across the countries, whereas economic inequality is positively related to the extent of applicant faking to a substantial extent. These findings imply that people are sensitive to inequality within countries and that inequality relates to faking, because inequality might actuate other psychological processes (e.g., envy) which in turn increase the probability for unethical behavior in many forms.     

The (non-)benefit of choosing: If you get what you want it is not important that you chose it

Self-Determination Theory argues that autonomy plays a major role in intrinsic motivation. Autonomy can be operationalized as choice. Whether positive effects on motivation are caused by the mere act of choosing or by confounding variables is still unclear. In this study (N?=?299, M_age?=?13.1?±?0.6 years), students could work with two polarizing animals. The first group was allowed to choose (choosing & match), two groups were not. In these groups, the teacher allocated the animals to the students resulting in a second group that received the wanted animal (no choosing & match), and a third group that received the unwanted animal (no choosing & no match). Situational motivation and flow experience were assessed. Regarding intrinsic motivation and flow, students in the no choosing & match treatment scored the highest, students of the no choosing & no match group the lowest. In conclusion, matching and not choosing made the difference.     

Verbal descriptions of spatial information can interfere with picture processing

Two studies are reported that tested the assumption that learning is improved by presenting text and pictures compared to text only when the text conveys non-spatial rather than spatial information. In Experiment 1, 59 students learned with text containing either visual or spatial contents, both accompanied by the same pictures. The results confirmed the expected interference between the processing of spatial text contents and pictures: Learners who received text containing spatial information showed worse text and picture recall than learners who received text containing visual information. In Experiment 2, 85 students were randomly assigned to one of four conditions, which resulted from a 2×2 between-participants design, with picture presentation (with vs without) and text contents (visual vs spatial) as between-participants factors. Again the results confirmed the expected interference between processing of spatial text information and pictures, because beneficial effects of adding pictures to text were observed only when the texts conveyed visual information. Importantly, when no pictures were present no differences were observed between learners with either visual or spatial texts contents, indicating that the observed effects are not caused by absolute differences between the two texts such as their difficulty. The implications of these results are discussed.
