The theory of uncertainty orientation: a mathematical reformulation

In this paper, we present a mathematical formulation derived from the theory of uncertainty orientation (In R.M. Sorrehtino, & E.T. Higgins (Eds.), the handbook of motivation and cognition: Foundations of social behaviour, Vol. 1 (pp. 379-403). New York: The Guilford press; The uncertain mind: Individual differences in facing the unknown. London: Erlbaum (UK), Taylor & Francis). This formulation integrates affective and informational influences on thought and action. It is a model of self-regulation where the need to maintain clarity and the need to attain clarity are considered as two independent informational tendencies. These informational tendencies are influenced by the degree of self-relevance and the amount of perceived situational uncertainty. In addition, they are multiplicative with affective approach and avoidance tendencies, leading to accentuation or inhibition of behaviors expressed in action. It is further demonstrated that when the nondominant action tendency is instigated, secondary sources of motivation are expressed. This model not only accounts for past data, but also permits exploration using computer simulation. In addition, many new and testable hypotheses, including those related to affect and dynamical decision theory, are generated.     

The effect of volition on the stability of bimanual coordination

The authors investigated how the intention to passively perform a behavior and the intention to persist with a behavior impact upon the spatial and temporal properties of bimanual coordination. Participants (N = 30) were asked to perform a bimanual coordination task that demanded the continuous rhythmic extension-flexion of the wrists. The frequency of movement was scaled by an auditory metronome beat from 1.5 Hz, increasing to 3.25 Hz in.25-Hz increments. The task was further defined by the requirement that the movements be performed initially in a prescribed pattern of coordination (in-phase or antiphase) while the participants assumed one of two different intentional states: stay with the prescribed pattern should it become unstable or do not intervene should the pattern begin to change. Transitions away from the initially prescribed pattern were observed only in trials conducted in the antiphase mode of coordination. The time at which the antiphase pattern of coordination became unstable was not found to be influenced by the intentional state. In addition, the do-not-intervene set led to a switch to an in-phase pattern of coordination whereas the stay set led to phase wandering. Those findings are discussed within the framework of a dynamic account of bimanual coordination.     

The complexities of complex span: explaining individual differences in working memory in children and adults

Two studies are presented that investigated the constraints underlying working memory performance in children and adults. In each case, independent measures of processing efficiency and storage capacity are assessed to determine their relative importance in predicting performance on complex span tasks,which measure working memory capacity. Results show that complex span performance was independently constrained by individual differences in domain-general processing efficiency and domain-specific storage capacity. Residual variance, which may reflect the ability to coordinate storage and processing, also predicted academic achievement. These results challenge the view that complex span taps a limited-capacity resource pool shared between processing and storage operations. Rather, they are consistent with a multiple-component model in which separate resource pools support the processing and storage functions of working memory.     

Correlates of motives for suicide

Analysis of a large sample of suicide notes from 262 suicides in Australia showed separated/divorced suicides and suicides who abused alcohol were more likely to give love/romance as a precipitant for suicide while those who used gas (natural or car exhaust) were more likely to give depression and guilt as a motive.     

Psychological type and attitude toward Christianity: a replication

A sample of 149 university students completed the Francis Psychological Type Scales together with the Francis Scale of Attitude Toward Christianity. The data indicated that university students classified as Feeling Types hold a more positive attitude toward Christianity than those classified as Thinking Types. These findings replicate the 1999 report of Jones and Francis.     

Functional imaging of 'theory of mind'

Our ability to explain and predict other people's behaviour by attributing to them independent mental states, such as beliefs and desires, is known as having a 'theory of mind'. Interest in this very human ability has engendered a growing body of evidence concerning its evolution and development and the biological basis of the mechanisms underpinning it. Functional imaging has played a key role in seeking to isolate brain regions specific to this ability. Three areas are consistently activated in association with theory of mind. These are the anterior paracingulate cortex, the superior temporal sulci and the temporal poles bilaterally. This review discusses the functional significance of each of these areas within a social cognitive network.     

Why Are We Reluctant to Sell Friendship?1

There are a number of indicators that people try to keep money out of social relationships, and a number of reasons why such separation might occur: undermining of intrinsic motivation, contamination of signals of friendship, and the apparently irrational tainting influence of money. Two experiments in which psychology students participated in brief conversations under various payment conditions found little evidence for payment adversely affecting the social interactions. A third study comparing a service group (hairdressers) that has considerable social interaction with its customers and a control group indicated that the former did not suffer any undermining of normal social motivation. Overall, the findings suggest that the separation of money from social relationships may not have a rational foundation.

Cultural Similarity, Foreign Policy Actions, and Regime Perception: An Experimental Study of International Cues and Democratic Peace

This study examines previous explanations of democratic peace in light of sociocultural factors and foreign policy actions that influence public perceptions of another country. Two experiments assessed the effects of relevant sociocultural and foreign policy action cues on perception of the regime type of a target nation and on public approval of the use of force. The findings suggest that sociocultural cues affect regime perception. Moreover, perceived similarity of a target nation and foreign policy actions are significant determinants of the public approval of the use of force in addition to perceptions of regime type.
