Psychosocial Factors Associated With Stage of Change for Contraceptive Use Among Women at Increased Risk for HIV and STDs

This study assessed the psychosocial factors associated with contraceptive use among inner-city women at risk for HIV/STDs by using the transtheoretical model of behavior change. The five-city study group of women aged 15 to 34 years was recruited from neighborhoods, social service agencies and shelters ( n = 998). We measured stages of change for contraceptive use and assessed theoretically proposed factors associated with being at a higher stage. Variables such as perceived advantages of contraceptive use and normative support for use were very important at early stages, but less important in later stages. However, self-efficacy was important in both early (OR =1.5) and later (OR = 1.6) stages, suggesting that women's confidence in their ability to initiate and sustain contraceptive use is crucial.     

Negative Intergroup Contact and Radical Right‐Wing Voting: The Moderating Roles of Personal and Collective Self‐Efficacy

This study examines whether negative contact with immigrants promotes voting for radical right‐wing parties, to what extent this relationship can be explained by feelings of outgroup threat, and whether this relationship depends on perceived personal and collective self‐efficacy. Hypotheses were tested among 630 native Dutch respondents, mainly living in multicultural neighborhoods. The results show that negative contact with immigrants is associated with feelings of personal (egocentric) and group (sociotropic) threat, and both these feelings, in turn, are associated with radical right‐wing voting. However, negative intergroup contact is less strongly related to egocentric threat when individuals feel able to personally address negative situations with other people (personal self‐efficacy). Furthermore, the findings suggest that negative intergroup contact is less strongly related to sociotropic threat when individuals believe that people in their neighborhood are able to collectively address some negative situations (collective self‐efficacy).     

Impaired auditory recognition memory in amnesic patients with medial temporal lobe lesions

Two tests of auditory recognition memory were given to four patients with bilateral hippocampal damage (H+) and three patients with large medial temporal lobe lesions and additional variable damage to lateral temporal cortex (MTL+). When single stimuli were presented, performance was normal across delays as long as 30 sec, presumably because information could be maintained in working memory through rehearsal. When lists of 10 stimuli were presented, performance was impaired after a 5-min delay. Patients with MTL+ lesions performed marginally worse than patients with H+ lesions, consistent with findings for recognition memory in other modalities. The findings show that auditory recognition, like recognition memory in other sensory modalities, is dependent on the medial temporal lobe.     

Examining assumptions about item responding in personality assessment: should ideal point methods be considered for scale development and scoring?

The present study investigated whether the assumptions of an ideal point response process, similar in spirit to Thurstone's work in the context of attitude measurement, can provide viable alternatives to the traditionally used dominance assumptions for personality item calibration and scoring. Item response theory methods were used to compare the fit of 2 ideal point and 2 dominance models with data from the 5th edition of the Sixteen Personality Factor Questionnaire (S. Conn & M. L. Rieke, 1994). The authors' results indicate that ideal point models can provide as good or better fit to personality items than do dominance models because they can fit monotonically increasing item response functions but do not require this property. Several implications of these findings for personality measurement and personnel selection are described.     

Neural processing associated with true and false memory retrieval

We investigated the neural bases for false memory with fMRI by examining neural activity during retrieval processes that yielded true or false memories. We used a reality monitoring paradigm in which participants saw or imagined pictures of concrete objects. (A subsequent misinformation task was also used to increase false memory rates.) At test, fMRI data were collected as the participants determined whether they had seen or had only imagined the object at study. True memories were of seen pictures accurately endorsed as seen, and for false memories were of imagined pictures falsely endorsed as seen. Three distinct patterns of activity were observed: Left frontal and parietal activity was not different for true and for false memories, whereas activity was greater for true than for false memories in occipital visual regions and posterior portions of the parahippocampal gyrus, and activity was greater for false than for true memories in right anterior cingulate gyrus. Possible interpretations are discussed.     

Intact visual perceptual discrimination in humans in the absence of perirhinal cortex

While the role of the perirhinal cortex in declarative memory has been well established, it has been unclear whether the perirhinal cortex might serve an additional nonmnemonic role in visual perception. Evidence that the perirhinal cortex might be important for visual perception comes from a recent report that monkeys with perirhinal cortical lesions are impaired on difficult (but not on simple) visual discrimination tasks. We administered these same tasks to nine amnesic patients, including three severely impaired patients with complete damage to perirhinal cortex bilaterally (E.P., G.P., and G.T.). The patients performed all tasks as well as controls. We suggest that the function of perirhinal cortex as well as antero-lateral temporal cortex may differ between humans and monkeys.     

Cognitive deficit or cognitive distortion in childhood depression

Three studies were conducted to evaluate cognitive disturbance and depression in children. In Study I, 47 sixth-grade children, including 17 who received a DSM-III diagnosis of depression, and their parents were independently interviewed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children, and they completed the Parent-Child Depression Inventory. Children completed the Children's Depression Inventory, the Matching Familiar Figures Test, and the My Standards Questionnaire. Results of Study 1 were consistent across raters and measures: Depression was associated with a negative style of processing self-evaluative information, while being unrelated to a processing deficit. A second study was initiated to replicate the results of Study 1 and to extend them to a wider age range of children. Thirty- eight third-, fourth-, fifth-, and sixth-grade children, half of whom were depressed and half of whom indicated a minimum of depressive symptomatology on the Children's Depression Inventory, completed the Matching Familiar Figures Test and the My Standards Questionnaire. Results were very similar to those found in Study 1. A third study was conducted to test whether the self-perceptions of depressed children were accurately negative or negatively distorted, as judged against their teachers' observations of them. Results supported the hypothesis that depressed children exhibit a distorted style of processing self-evaluative information. The implications of the results for theory and treatment were discussed.This research was funded by the Hogg Foundation for Mental Health, The University of Texas at Austin.
