From an instructional design perspective, the presence of support devices, also known as tools in computer-based learning environments (CBLEs) aims to enhance learning outcomes/performance [1]. Nevertheless, independent of the intentions behind the design of the tools, tools are value-neutral until learners use them [2]. How (in-) adequately learners use the tools affects the tools functionalit...

Research on union renewal often cites a critical role for lay activism. This study examines determinants of activism and activism intentions among a broadly representative sample of U.S. union members. Hypotheses are developed from theory and previous research on union commitment and participation. Results for current activism are generally consistent with prior work. Extending the model to fut...

The effects of peer group rejection on 7- and 9-year-old children's (N= 192) reactive, displaced, and proactive aggression were examined in a group simulation study. Children were assigned membership in a pretend social group for a drawing competition and were then rejected or accepted by their group. Their direct and indirect aggressive intentions towards either the ingroup or outgroup were as...

Compensatory Health Beliefs (CHBs) are defined as beliefs that the negative consequences of unhealthy behaviours can be compensated for by engaging in healthy behaviours. CHBs have not yet been investigated within a framework of a behaviour change model, nor have they been investigated in detail regarding smoking. Thus, the aim of this study was to investigate on a theoretical basis whether smo...

This paper shows an extended Discourse Representation Theory (DRT) model which represents clarification dialogue and clarification dialogue acts and relates them to agents’ intentions. Agents’ intentions are linked to the dialogue acts associated with their utterances. The effect dialogue acts have on the speaker and the hearer is translated into an extended computational DRT model and linked t...

• Mimicry effects are difficult to regulate as people are not usually aware of their influence. • In two studies, planning with implementation intentions regulated mimicry effects. • Planning how to be unprejudiced strengthened the mimicry–liking effect for unlikable others. • Planning how to be thrifty weakened the persuasive effects of being mimicked on spending. • Mere goal intentions to be ...

This study explores the consequences of fostering empathy-for both victims and perpetrators-after large-scale violent events. Participants (N = 834) read a description of a school shooting and were randomly assigned to one of six conditions revealing varying amounts of background information about the victim and the perpetrator of violence. The impact of empathy on reactions toward the victim a...

Introspectively, the awareness of actions includes the awareness of the intentions accompanying them. Therefore, the awareness of self-generated actions might be expected to differ from the awareness of other-generated actions to the extent that access to one's own and to other's intentions differs. However, we recently showed that the perceived onset times of self- vs. other-generated actions ...

Some children's social activities are structured by joint goals. In previous research, the criterion used to determine this was relatively weak: if the partner stopped interacting, did the child attempt to re-engage her? But re-engagement attempts could easily result from the child simply realizing that she needs the partner to reach her own goal in the activity (social tool explanation). In tw...
