The role of personality in exposure and reactivity to interpersonal stress in relation to arthritis disease activity and negative affect in women.

The role of personality in the stress process was examined in older women with rheumatoid arthritis (RA) and osteoarthritis (OA) and in healthy controls (HCs). Reactivity was examined in relation to arthritis disease activity and negative affect. Interpersonal sensitivity and neuroticism were measured in questionnaires, and interpersonal stress, negative affect, and disease activity were assessed weekly for 12 weeks. Interpersonal sensitivity was defined as an excessive sensitivity to the behavior and feelings of others. Regarding exposure, neuroticism was related to interpersonal stress for all groups. Regarding reactivity, interpersonal sensitivity interacted with interpersonal stress to predicted elevations in negative affect in all groups and elevations in disease activity in the arthritis groups. There were no significant differences in the effects.     

Health Downturns and Predictors of Suicidal Ideation: An Application of the Baumeister Model

Suicidal thoughts and attempts have been studied from a number of perspectives, but only recently has an attempt been made to incorporate many different psychological perspectives into one framework. Baumeister (1990) has integrated personality and social psychological perspectives into one sequential model, moving from instigating events to a final stage of suicidal thoughts. Employing a sample of older adult subjects undergoing the stresses of a recent health downturn, this study tested a four-stage model of suicidal ideation based on many of the components proposed by Baumeister. Structural equation modeling achieved a good fit to the data. Results are discussed in terms of the importance of including life events, particularly poor health, and cognitive variables such as confusions in thinking, in understanding suicidal ideation.

Individual differences in speed of phonemic analysis, visual analysis, and reading.

College student subjects (Ss) classified phrases as making sense or not according to sound in one condition, according to visual appearance in another, and in abasic task in which either strategy would yield right answers. Ss who were relatively fast in the visual condition were faster at the basic task than Ss who were relatively fast in the sound condition. Other results suggested that the former Ss used a visual strategy in the basic task while the latter used a phonemic strategy.     

Pain cues and uncertainity as determinants of aggression in a situation involving repeated instigation.

In contrast to the Buss aggression paradigm, a situation was employed in which subjects were given an expanded range of response options and were exposed to instigation throughout their response period. It was found that (a) despite these changes pain cues depressed aggressiveness in the present situation as they generally do in the Buss paradigm, but that this effect only occurred where the subjects' aggression was initially ineffective in changing their target's behavior; (b) situational uncertainity, which is minimal in a Buss-type situation, was related to aggressiveness; (c) subjects tended to match rather than attempt to control the responses of the target; and (d) the present paradigm is capable of isolating a personality variable related to overall aggressiveness. These data are discussed in terms of other recent paid cue studies that deviate from the standard Buss situation. Generally, the findings suggest the potential of increasing the range of situations in which aggression is studied.     

An analysis of the word-superiority effect

It is easier to decide which of two letters was presented tachistoscopically if the critical letter was in a word rather than in a scrambled word. We showed that this word-superiority effect holds just as strongly for pronounceable nonwords as for words, even when the critical letters are constant over all trials. This finding rules out word meaning and familiarity as variables accounting for the effect. In addition, it was found that the superiority of pronounceable stimuli holds for two-letter stimuli as well as four, and it is therefore concluded that the effect is not due to a memory limitation. An explanation of the effect in terms of the use of additional acoustic information is ruled out by showing that the effect was not diminished when the two possible words sounded exactly alike. An experiment using correctly and incorrectly spelled chemical formulas suggested that spelling regularities, regardless of pronounceability per se, account for the superiority effect. Finally, when decisions about two critical letters must be made on each trial, the correlation between being correct on one and on the other is higher for pronounceable stimuli under some conditions.
