We investigated the association of suicidal ideation and behavior with depression, anxiety, and alcohol abuse in a Canadian Arctic Inuit community. Inuit (N = 111) from a random sample of households completed assessments of anxiety and depression, alcohol abuse, and suicidality. High rates of suicidal ideation within the past week (43.6%), and suicide attempts within last 6 months (30%), were reported. Ideation was more frequent among younger persons, whereas those favoring local native language were less likely to report a wish to die. Higher overall suicidality scores were associated with higher anxiety, and alcohol abuse, but not with depression or gender. Implications for future research are discussed. 相似文献

Three experiments examined transfer across form (words/pictures) and modality (visual/ auditory) in written word, auditory word, and pictorial implicit memory tests, as well as on a free recall task. Experiment 1 showed no significant transfer across form on any of the three implicit memory tests,and an asymmetric pattern of transfer across modality. In contrast, the free recall results revealed a very different picture. Experiment 2 further investigated the asymmetric modality effects obtained for the implicit memory measures by employing articulatory suppression and picture naming to control the generation of phonological codes. Finally, Experiment 3 examined the effects of overt word naming and covert picture labelling on transfer between study and test form. The results of the experiments are discussed in relation to Tulving and Schacter's (1990) Perceptual Representation Systems framework and Roediger's (1990) Transfer Appropriate Processing theory. 相似文献

Subjects who make repetitive saccadic eye movements before a memory test subsequently exhibit superior retrieval in comparison
with subjects who do not move their eyes. It has been proposed that eye movements enhance retrieval by increasing interaction
of the left and right cerebral hemispheres. To test this, we compared the effect of eye movements on subsequent recall (Experiment
1) and recognition (Experiment 2) in two groups thought to differ in baseline degree of hemispheric interaction—individuals
who are strongly right-handed (SR) and individuals who are not (nSR). For SR subjects, who naturally may experience less hemispheric
interaction than nSR subjects, eye movements enhanced retrieval. In contrast, depending on the measure, eye movements were
either inconsequential or even detrimental for nSR subjects. These results partially support the hemispheric interaction account,
but demand an amendment to explain the harmful effects of eye movements for nSR individuals. 相似文献

Progressive-ratio (PR) schedules were used to identify the break point (i.e., the last schedule value completed) for 2 reinforcers under single and concurrent schedules. After the respective break points were established, the same reinforcers were presented under concurrent fixed-ratio (FR) schedules that were yoked to the break points obtained with the PR schedules. Results suggested that the participants responded more for the high-preference item than for the low-preference item, regardless of the presentation arrangement (single or concurrent presentations). This pattern of responding was maintained when the reinforcers were presented under dissimilar FR schedules. The results suggest that responding for differentially preferred stimuli may vary as a function of differences in schedule requirements. 相似文献
