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.     

K-ABC simultaneous processing, DAS nonverbal reasoning, and Horn's expanded fluid-crystallized theory.

Horn's distinction between--fluid intelligence (Gf) and visualization (Gv) was investigated with two Nonverbal Reasoning subtests from the Differential Ability Scales and three Simultaneous Processing subtests from the Kaufman Assessment Battery for Children. The sample comprised a predominantly Euro-American groups of 57 normal boys and girls between the ages of 6 and 12 years. Principal factor analysis yielded clear-cut Gf and Gv dimensions. The Gf factor was composed both of Differential Ability Scales and Kaufman-ABC subtests, suggesting that the construct of simultaneous processing is not merely a measure of Gv, as researchers have hypothesized, but also measures Horn's Gf fluid intelligence to a considerable extent.     

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.     

Race, culture, and psychotherapy: transference to minority therapists

We present observations on the use of racial and cultural stereotypes in psychoanalytic psychotherapy with patients from the majority culture and with those from minority backgrounds. Earlier work has centered on black/white patient dyads and has not taken other possible combinations into account. "Race" and "culture" have sometimes been used synonymously. Our clinical experience indicates that there is some overlap in the themes of transferences to us as members of different racial minorities. We note, however, that for the African-American therapist, projections are more often based on racial stereotypes, whereas for the Chinese-American therapist, projections are based more on cultural assumptions. When careful attention is paid to the manifestations of racial and cultural stereotyping, much can be learned about the patient's inner life, to the benefit of the analytic work.     

Change of intensity fails to produce an irrelevant sound effect: implications for the representation of unattended sound.

Sequences of changing sounds that are irrelevant to the task at hand disrupt serial recall appreciably even though participants are instructed to ignore the sounds. Three experiments, which compared the effect of changing token identity with that of changing intensity in the 55- to 85-dB (A) range, were conducted. Although serial recall was impaired by changes in token identity, no disruptive effects of a change in intensity were found. This was replicated using speech and nonspeech. Overall, the absence of a changing intensity effect was based on an analysis of the performance of 115 participants in a design whose power was .98. This outcome suggests that the representation of intensity in preattentive processing of auditory stimuli is somewhat different from that of other acoustic features.     

Correlations for timing consistency among tapping and drawing tasks: evidence against a single timing process for motor control.

Three experiments were conducted to examine whether timing processes can be shared by continuous tapping and drawing tasks. In all 3 experiments, temporal precision in tapping was not related to temporal precision in continuous drawing. There were modest correlations among the tapping tasks, and there were significant correlations among the drawing tasks. In Experiment 3, the function relating timing variance to the square of the observed movement duration for tapping was different from that for drawing. The conclusions drawn were that timing is not an ability to be shared by a variety of tasks but instead that the temporal qualities of skilled movement are the result of the specific processes necessary to produce a trajectory. These results are consistent with the idea that timing is an emergent property of movement.     

Better discrimination of small changes in commonly encountered than in less commonly encountered auditory stimuli

Results from 3 auditory tasks revealed that small changes made in stimuli commonly encountered in everyday life are more easily discriminated than are the same changes made in stimuli not as commonly encountered. The tasks required discrimination of a frequency difference in 1 tone of 6-tone chords or nonchords, discrimination of a duration difference in 1 note of common tunes or nontunes, and discrimination of the deletion of a band of frequencies from speech sounds played forward or backward. Different crews of college-aged listeners served in the different tasks. If future research shows this difference in discriminability to be a general property of commonly encountered stimuli--attributable to a difference in the way they are processed in the nervous system--then discrimination tests of this sort could become useful for assessing whether stimuli have made the transition from one form of processing to the other.     

A developmental grammar for syllable structure in the production of child language.

The order of acquisition of Dutch syllable types by first language learners is analyzed as following from an initial ranking and subsequent rerankings of constraints in an optimality theoretic grammar. Initially, structural constraints are all ranked above faithfulness constraints, leading to core syllable (CV) productions only. Subsequently, faithfulness gradually rises to the highest position in the ranking, allowing more and more marked syllable types to appear in production. Local conjunctions of Structural constraints allow for a more detailed analysis.     

Masked syllable priming of English nouns.

This study investigates the role of sublexical units in the phonological encoding of English single-word production in a word-naming task (Experiment 1) and a picture-naming task (Experiment 2). Targets corresponded to bisyllabic English nouns with word-initial stress which varied on the structure of their first syllable: CV (e.g., pi.lot), CVC (e.g., pic.nic), or CV[C] (e. g., pi[ll]ow).1 Targets were preceded by a visually masked prime that either matched their first syllable (e.g., pi%%% - pi.lot) or that was one segment longer (e.g., pil%% - pi.lot) or shorter (e.g., pi%%%% - pic.nic) than the first syllable. Response times were compared to a neutral control condition (e.g., %&$%% - pi.lot) to measure the priming effects (either facilitation or inhibition). Results showed significant facilitation for both the CV and the CVC conditions. However, contrary to previous findings, there was no interaction between the syllabic structure of the prime and the target.
