The impact of object animacy on the appraisal of causality

The goal of this study was to examine whether animacy of objects affected the appraisal of a causal relationship when one object was observed to propel the other either immediately, after a delay, or at a distance. Participants rated the degree of causal interaction either before or after an extended experience with observing the interactions. We expected that spatial distance would have little effect when objects were seen as animate (because social interactions often span spatial gaps) and would have a degrading effect when objects were appraised as inanimate. Motion animacy appeared to attenuate the impact of a gap and to decrease initial causal judgments for direct collisions. Explicitly informing participants about the nature of the objects had a strong impact. Experience with the causal task affected ratings to a greater extent when the objects were explicitly described as nonliving rather than living.     

Influence of experience on postural control: effect of expertise in gymnastics

The authors investigated how expertise in motor skills that require fine postural control, such as gymnastics, influences postural regulation. Gymnasts and nongymnasts performed a postural stabilization task after anterior-posterior destabilization while looking at a target in front of them. The authors recorded and analyzed the center of pressure and the ankle, knee, and hip displacements. Gymnasts were able to react rapidly after destabilization to decrease their center of pressure and the angular movements. Moreover, they used their knees to stabilize posture, whereas the nongymnasts used their hips. These findings suggest that specific postural experience modifies the ability to coordinate and regulate posture. The authors discuss these results from an ecological perspective.     

Pathways to suicidal behaviors in childhood

Path analyses were applied to test a model that includes internalizing and externalizing behavior problems as predictors of suicidal behaviors in children. Parents of an inpatient sample of boys (N=87; M age=9.81 years) rated the frequency of suicidal ideation and completed standardized measures of behavior problems. Blind raters rated the severity of the children's suicidal behaviors. Results revealed a significant direct effect for suicidal ideation on suicide attempt and for depressive symptoms on suicidal ideation. There was also a significant indirect path from impulsivity to suicidal ideation through aggressive and depressive symptoms. Clinical implications are discussed.     

Links between casino proximity and gambling participation, expenditure, and pathology.

Two studies investigated the relationship between casino proximity and gambling participation, expenditure, and pathology. In Study 1, 8,842 participants were categorized into 1 of 4 driving distances from their home to the nearest casino in the province of Quebec: 0-100 km, 100.01-200 km, 200.01-300 km, or 300.01-981 km. In Study 2, 5,158 participants, who lived within a 100-km driving distance from the Montreal casino, were classified into 1 of 5 equidistant, 20-km driving distances. A survey company interviewed participants regarding their gambling habits. Results indicated a positive link between casino proximity and gambling participation (at the provincial and Montreal levels) and expenditure (at the provincial level only) but no link with the current prevalence rate of probable pathological gambling or of problem gambling. In a setting in which many types of gambling activities are available, casino proximity in itself does not appear to explain the rate of gambling-related problems. It is necessary to continue prospective research on exposure and adaptation theories as potential explanations for the development of pathological gambling.     

On how a child's awareness of thinking informs explanations of thought insertion

Theories of thought insertion have tended to favour either the content of the putatively alien thought or some peculiarity within the experience itself as a means of explaining why the subject differentiates one thought from another in terms of personal ownership. There are even accounts that try to incorporate both of these characteristics. What all of these explanations share is the view that it is unexceptional for us to experience thought as our own. The aim of this paper is to consider the means by which this awareness of the myness of thought occurs. Why is it that I, as the subject of thought, typically experience a thought as mine? Using research which investigates the development of a child's awareness of the act of thinking, I will evaluate leading explanations of thought insertion. It is my contention that by understanding the means by which the awareness of one's ownership of thought develops, we can better assess explanations of thought insertion; and whilst, at present, no theory is fully able to explain the condition, the incorporation of developmental research suggest that we should favour one in particular.     

Feedback and driver situation awareness (SA): A comparison of SA measures and contexts

The dominant technological trajectory in vehicle design brings with it similarly dominant driver performance issues in regard to vehicle feedback and driver situational awareness (SA). Three experiments are reported in this paper that describe not only the effects on driver SA of manipulations of vehicle feedback but also illuminate issues concerned with SA measurement methods and contexts. The findings suggest that current trends in vehicle design may contribute little towards a driver’s SA and, in fact, may actually show a generalized trend towards decreasing it. The efficacy of verbal protocol and probe recall SA measurement techniques is noted in terms of observing this effect. On the other hand, a concerning dissociation occurred with findings from a self-report measure of SA. Drivers appear to show a concerning lack of self-awareness of their SA and, indeed, any shortfall in it.     

Women's eye contact and men's later interest: two field experiments

Previous studies indicated various nonverbal behaviors including eye contact of women are associated with men's approach; however, duration of the eye contact was not tested. In Exp. 1, a female confederate established eye-contact of 3 sec. or 1 sec. with a man when entering a bar. Duration of returned glance was the dependent variable. Analysis showed mean duration of the return glance was statistically shorter in the 1-sec. condition. In Exp. 2, the confederate made eye contact with a man and looked at him less than 1 sec., 2 sec., or 4 sec. The presence versus absence of smile was the dependent variable. Longer duration of eye contact was associated with an increase of smiling.     

Pilot study for assessing the behaviors of patients with schizophrenia towards a virtual avatar.

This study examined whether a virtual avatar could be perceived as a real human by patients with mental disease, especially schizophrenia, as well as whether a virtual avatar could be applied to acquiring patients' behavior characteristics in a short conversation situation. The virtual avatar has been used for various applications which need to communicate with other person or to train or educate by showing humanlike behavior. Recently, many researches have shown that the virtual avatar technology has been enhanced and the avatar could be perceived like real human. A virtual avatar, standing in a virtual room, was designed for this study. Tasks to approach, initiate a talk, and answer to avatar's questions was assigned to the 11 patients with schizophrenia. As behavioral parameters in the virtual environment, the interpersonal distance and the verbal response time were acquired. In addition, the Positive and Negative Syndrome Scale (PANSS) for patients was administered in order to investigate the relationship between patients' symptomatic characteristics and behavior parameters. The interpersonal distance was negatively correlated with the negative syndrome scale, a subscale of PANSS, which is consistent with previous research reporting the relationship between interpersonal distance and a real person's image. The verbal response time, however, was not correlated with any other subscale of PANSS. After analyzing subitems of the negative syndrome of PANSS, two positive correlations were found: one was with blunted affect and the other was with poor rapport. We concluded that the virtual avatar could be perceived as a real human by schizophrenic patients and the avatar could draw the schizophrenic patients' behavior characteristics.
