Negative and positive cognition in depressed and nondepressed chronic-pain patients

Several studies have suggested that depressed pain patients evidence more cognitive distortion than nondepressed pain patients and healthy controls. Although these studies have generally supported notions relating cognitive distortion to depressive functioning, other aspects of dysfunctional cognition have not been assessed in the chronic-pain population. The present study examined negative and positive automatic thoughts and attributional style in depressed pain patients, nondepressed pain patients, and healthy controls. Depressed chronic-pain patients were found to exhibit significantly more negative automatic thoughts than nondepressed pain patients and healthy controls. Conversely, nondepressed chronic-pain patients reported significantly more positive automatic thoughts than did depressed patients and healthy controls. No significant differences were found for attributional style. These results suggest that different cognitive-behavioral interventions might be considered for depressed compared to nondepressed chronic-pain patients.     

A Historical Survey of Police Suicide in Queensland,Australia, 1843–1992

Police suicide research has yielded inconsistent results. An opportunity presented to survey Queensland police suicides in a historical context and add to the existing literature; the study describes changes in police suicide over time, the associated characteristics, and opportunities for intervention. Suicides were examined from the origins of police in Queensland in 1843 up to 1992. Suicide rates were higher earlier, around 60 per 100,000, declining to around 20 per 100,000 recently. The recent rate is lower than most other police studies but the same as the general community (employed). Most suicides were associated with psychological and physical ill health, alcohol abuse, and domestic problems, in keeping with general community surveys. However, occupational problems were more evident than is generally the case. The proximity in time of disciplinary events and suicides was striking. Future studies should explore the interactions between these factors.     

The role of three-dimensional depth cues in infants' perception of partly occluded objects

Newborn infants were familiarized to a three dimensional display consisting of a rod which moved behind a central occluder, so that only the top and bottom of the rod were visible. The infants' eyes were 38 cm from the rod and the occluder was 15 cm in front of the rod, a separation intended to ensure that the gap between the two was detected by the infants. On subsequent test trials the infants looked longer at a complete rod than at two rod pieces, suggesting that the hidden unity, or completeness of the rod had not been perceived. In a study by Johnson and Náñez (in press), using computer. generated stimuli, 4 month olds perceived the hidden unity of a similar display presented on a VDU in the complete absence of three. dimensional depth cues. Taken together, these findings suggest that, for these displays, perception of three. dimensional depth cues is not necessary for the detection of the unity of partially hidden objects. It is suggested that age changes in early infancy in the perception of occluded objects may result either from the emergence of abilities to perceive objects from kinematic information or from the emergence of sensitivity to that information itself.     

The effect of scene removal on inhibition of return in a cue-target task

Inhibition of return (IOR) is thought to be a phenomenon that biases orienting toward novel stimuli and/or facilitates foraging search. Although IOR has been explored using both the spatial cueing paradigm and the search paradigm, there is significant disagreement among scholars over whether these paradigms are reflecting the same underlying mechanism. We sought to address this disagreement by exploring whether a manipulation known to impact IOR in search - maintenance versus removal of the scene - might have a similar impact in the spatial cuing paradigm. As has been observed in both the cuing and search paradigms, we obtained a robust gradient of IOR around the cued location. Importantly, as in search tasks, scene removal resulted in the abolishment of IOR. This similarity lends support to the view that the spatial cuing and search paradigms are exploring the same IOR phenomenon.
