Dynamics of hostile aggression: Influence of anger,hurt instructions,and victim pain feedback

The research basically examined some of the dynamics of hostile aggression by looking at the effects of different Buss procedure instructions and levels of victim pain feedback on the aggressive behavior of angered and nonangered men. In a 2 × 2 × 2 completely crossed factorial experiment, male undergraduates were initially either angered or not by an experimental accomplice. When later given the ostensible opportunity to administer shocks to the same accomplice in a typical Buss procedure, the subjects were either told that longer and more intense shocks would probably interfere with the person's learning as well as causing him more pain (hurt instructions) or given no information about the effects of shocks on learning (standard instructions). Finally, after each shock they administered, the subjects were provided with either high or low victim pain feedback. The angered men were significantly more aggressive than their nonangered counterparts, and a significant interaction between anger and instructions indicated this was especially true for the men given hurt instructions. Significant interactions between the other independent variables and trial blocks revealed that the angered men, particularly those receiving hurt instructions and high victim pain feedback, displayed the greates increases in aggression. The results provide qualified support for the derived proposition about hostile aggression that signs and/or knowledge of victim injury and pain can stimulate more intense aggression from angry individuals.     

Visual working memory in young children

Five experiments investigated immediate memory for drawings of familiar objects in children of different ages. The aims were to demonstrate younger children’s greater dependence on visual working memory and to explore the nature of this memory system. Experiment 1 showed that visual similarity of drawings impaired recall in young (5-year-old) children but not in older (10-year-old) children. Experiment 2 showed that younger and older children were affected in contrasting ways when the temporal order of recall was manipulated. Experiment 3 explored a recency effect found in backward recall and investigated its sensitivity to the presentation modality of materials used to produce retroactive interference (RI). For younger children, recency was reduced by visual but not by auditory-verbal RI; for older children, recency was more sensitive to auditoryverbal RI. Experiment 4 confirmed the effect of visual RI on visual recency in young children and showed that the same RI had little effect on their recall of spoken words. These results confirm younger children’s dependence on visual working memory. A final experiment showed that the effects of visual similarity and visual RI are additive, suggesting that they reflect different modes of accessing stored visuospatial information. Implications of these findings for developmental issues and for the nature of visual working memory are discussed.     

Property Designators,Predicates, and Rigidity

The article discusses an idea of how to extend the notion of rigidity to predicates, namely the idea that predicates stand in a certain systematic semantic relation to properties, such that this relation may hold rigidly or nonrigidly. The relation (which I call signification) can be characterised by recourse to canonical property designators which are derived from predicates (or general terms) by means of nominalization: a predicate signifies that property which the derived property designator designates. Whether signification divides into rigid and non-rigid cases will then depend uponwhether canonical property designators divide into rigid and non-rigid ones. But, I shall argue, they do not, and so the only notion of rigidity gained this way is trivial. To show this, I first focus on the kind of canonical property designators which could be thought to be nonrigid, canonical designators such as having the colour of ripe tomatoes which themselves contain non-rigid property designators. An argument to the effect that such complex canonical designators are non-rigid is rebutted, five arguments to the effect that they are rigid are formulated, and finally an explanation of their rigidity based on the general nature of canonical property designators is presented.     

Innovation across cultures: Connecting leadership,identification, and creative behavior in organizations

Innovation is considered essential for today's organizations to survive and thrive. Researchers have also stressed the importance of leadership as a driver of followers' innovative work behavior (FIB). Yet, despite a large amount of research, three areas remain understudied: (a) The relative importance of different forms of leadership for FIB; (b) the mechanisms through which leadership impacts FIB; and (c) the degree to which relationships between leadership and FIB are generalizable across cultures. To address these lacunae, we propose an integrated model connecting four types of positive leadership behaviors, two types of identification (as mediating variables), and FIB. We tested our model in a global data set comprising responses of N = 7,225 participants from 23 countries, grouped into nine cultural clusters. Our results indicate that perceived LMX quality was the strongest relative predictor of FIB. Furthermore, the relationships between both perceived LMX quality and identity leadership with FIB were mediated by social identification. The indirect effect of LMX on FIB via social identification was stable across clusters, whereas the indirect effects of the other forms of leadership on FIB via social identification were stronger in countries high versus low on collectivism. Power distance did not influence the relations.     

Disagreeing about who we are

ABSTRACT

One argument that has been suggested for conventionalism about personal identity is that it captures that certain disagreements about personal identity seem irresolvable, without being committed to the view that these disagreements are merely verbal. In this paper, I will take the considerations about disagreement used to motivate conventionalism seriously. However, I will use them to motivate a very different, novel, and as yet unexplored view about personal identity. This is the view that personal identity is a non-representational concept, the nature of which isn’t to be accounted for in terms of what entity it represents, but its non-representational role. I highlight that we find structurally very similar concerns about disagreement in another philosophical debate, namely in meta-ethics. But, in meta-ethics, such sorts of considerations are, traditionally, thought to support one distinctive view: meta-ethical expressivism, a non-representational view about normative thought and discourse. This suggests that we should take a similar view seriously for personal identity. I also develop what such an unfamiliar view might look like, using expressivism as a template. On this view, judgements about personal identity are plans that regulate who to hold accountable.     

Matching to complex stimuli under non-reinforced conditions: Errorless transfer from identity to arbitrary matching tasks

The present study investigated whether preschool children exposed to identity-matching tasks involving colour-form (CF) complex stimuli acquire arbitrary relations among those colours and forms. The children were first trained on an identity-matching task with green and yellow as samples and as comparisons (C-C task). Subsequent tests showed that the children matched: (1) samples green lambda and yellow pi, with comparisons green and yellow (CF-C), respectively; (2) samples black lambda and black pi, with comparisons green lambda and yellow pi (F-CF); (3) samples black lambda and black pi, with comparisons green and yellow (F-C); and (4) samples green and yellow, with comparisons black lambda and black pi (C-F). Other findings suggested that the F-C and C-F outcomes were likely only if the children were exposed to both CF-C and F-CF conditions. The results extend previous studies on emergent discriminations based on the elements of complex stimuli. The emergence of both form-colour and colour-form matching to sample permits an inference of symmetry, one of the properties of stimulus equivalence.     

Interrogative Belief Revision Based on Epistemic Strategies

I develop a dynamic logic for reasoning about ??interrogative belief revision??, a new branch of belief revision theory that has been developed in a small number of papers, beginning with E. J. Olsson and D. Westlund??s paper ??On the role of the research agenda in epistemic change?? [12]. In interrogative belief revision, epistemic states are taken to include a research agenda, consisting of questions the agent seeks to answer. I present a logic for revision of such epistemic states based on the notion of an epistemic strategy, a stable plan of action that determines changes in the agent??s research agenda. This idea is a further development of an idea put forward in [6], that changes in the research agenda of an agent should be determined by stable, ??long term?? research interests. I provide complete axioms and a decidability result for the logic.
