Executive functioning and compliance in HIV patients

25 adult HIV patients were evaluated in a study of appointments, medication, and compliance with restrictions on sexual activity. The Executive Interview (EXIT) was useful in assessing these patients for cognitive difficulties; compliance with medication and countertransference issues were negatively correlated with EXIT scores.     

Factors that may discourage annual mammography among low-income women with access to free mammograms: a study using multi-ethnic, multiracial focus groups

Age-eligible women enrolled in the National Breast and Cervical Cancer Early Detection Program can obtain free or low-cost mammograms annually, but many do not routinely complete rescreening. This study investigated the rescreening behavior of low-income women by conducting 8 focus groups in Texas with enrollees who had access to free mammograms. Concerns mentioned in the focus groups included fear of radiation, anxiety that the test might not find a cancer that was there, and worries that cancer might be detected. In all groups, some women mentioned the embarrassment, discomfort, or pain they experienced during a prior mammogram, although no one indicated they would refuse to have another mammogram because of these concerns. Findings highlight the useful insights that can be obtained from focus groups and underscore the need for more research on aspects of the experience of mammography that may affect rescreening.     

Is Bradburn's measure of psychological well-being fair to introverts? A study among 16- to 18-yr.-old students

The relationship between dimensions of personality characteristics and the perceived rearing attitude of parents in the Japanese population were investigated. The scores on a measure of perceived parental attitude of 153 normal female students, measured on the Parker Parental Bonding Instrument, were correlated with personality features from the Japanese version of the Cloninger Temperament and Character Inventory. Self-directedness, especially the subclasses of Responsibility vs Blaming and Congruent Second Nature vs Incongruent Habits, was significantly related to high scores on Maternal Care and low scores on Maternal Overprotection. The subscale of Self-acceptance vs Self-striving correlated only with low scores on Maternal Overprotection. Paternal Care was only related to the total scale scores on Self-directedness. Results suggest that some personality traits may be related to the perceived attitudes of parents, especially of the mother, during childhood.     

Relationship of arithmetic problem solving and reflective-impulsive cognitive styles in third-grade students

Different individuals approach mathematical problems in a variety of ways, with these different approaches also reflected in over-all cognitive styles. This investigation had two purposes, first, to determine whether good and poor arithmetic problem solvers differ substantially in cognitive style, and second, to determine whether the students, after training in techniques of solving arithmetic problems, improve their performance with no significant change in cognitive style. A total of 98 third graders participated (mean age 8.1 yr.; 50 boys, 48 girls). The Matching Familiar Figure Test was used to classify the students by cognitive style as either Reflective or Impulsive. Students also were given training with different problem-solving exercises for different arithmetic problems. The training program in problem-solving strategies did not improve performance on arithmetic problems for Reflective students; however, Impulsive students' performance did improve after training.     

Sex and the Barnum effect: rationality versus helpfulness

In 1998 Piper-Terry and Downey found that women accepted friends' bogus test interpretations more readily than did men and the researchers attributed this to women's helpfulness. Layne countered that women are more open and thus rationally expected their friends' interpretations to be more accurate. Later Downey asked participants how accurately they believed their friends could describe their personalities. Although this pilot study's sensitivity to differences was low, the women's accuracy ratings still tended to exceed those of men (p < .06) as Layne predicted. This may suggest that the rationality hypothesis is better supported than the female-helpfulness hypothesis.     

Defense mechanisms in alexithymia

The Polish version of the Toronto Alexithymia Scale-20 and Defense Mechanisms Questionnaire were completed by 387 university students. Scores on alexithymia correlate significantly with scores on the whole group of 12 immature defenses (Pearson r = .39, p < .001) and with scores on such individual immature defense mechanisms as Autistic Fantasy (r = .39), Somatization (r = .37), Projection (r = .32), and Displacement (r = .32). These results support other findings indicating that alexithymia is significantly associated with immature ego defenses.     

Interactions between color and word processing in a flanker task

To examine interactions between color and word attributes, participants responded, either manually or vocally, to a central target (color patch or word) flanked by a Stroop stimulus. Color and word attributes of the flanker affected both vocal and manual responding to color patches. Color and word flankers also affected manual responding to word targets, but only word flanker affected vocal responding to word targets. These results are not consistent with models (e.g., translational models) of Stroop tasks, which posit that interactions between colors and words occur only when vocal responding is required.     

Oscillatory brain dynamics, wavelet analysis, and cognition

On the basis of a systems theoretical approach it was hypothesized that event-related potentials (ERPs) are superpositions of stimulus-evoked and time-locked EEG rhythms reflecting resonance properties of the brain (Ba?ar, 1980). This approach led to frequency analysis of ERPs as a way of analyzing evoked rhythms. The present article outlines the basic features of ERP frequency analysis in comparison to ERP wavelet analysis, a recently introduced method of time-frequency analysis. Both methods were used in an investigation of the functional correlates of evoked rhythms where auditory and visual ERPs were recorded from the cat brain. Intracranial electrodes were located in the primary auditory cortex and in the primary visual cortex thus permitting "cross-modality" experiments. Responses to adequate stimulation (e.g., visual ERP recorded from the visual cortex) were characterized by high amplitude alpha (8-16 Hz) responses which were not observed for inadequate stimulation. This result is interpreted as a hint at a special role of alpha responses in primary sensory processing. The results of frequency analysis and of wavelet analysis were quite similar, with possible advantages of wavelet methods for single-trial analysis. The results of frequency analysis as performed earlier were thus confirmed by wavelet analysis. This supports the view that ERP frequency components correspond to evoked rhythms with a distinct biological significance.     

The relationship between adult happiness and self-appraised childhood happiness and events

The primary purpose of the present research was to relate questionnaire-assessed self-reported childhood happiness and events to adulthood happiness in 387 non-clinical participants. Although childhood happiness and adult happiness were found to be significantly correlated (r = .28, p < .001), there was little relationship between reported adult happiness and reported specific childhood events and circumstances. Childhood events and circumstances, however, were much more highly correlated with childhood happiness (R = .64). Thirty-four percent of the persons who said they were unhappy or very unhappy as a child, but only 9% who said they were happy or very happy as a child, reported that they were unhappy or very unhappy as adults.
