Cancer patients' interest and preferences for music therapy.

The reason for lack of routine integration of music therapy into healthcare may be that patients are not comfortable being involved in a music therapy intervention. Therefore, the goal of this study was to examine cancer patients' interest in and preferences for using 2 types of music therapy interventions, music-making and music listening. Sixty-five patients completed the Music Interest Survey in addition to standardized measures of coping, affect, anxiety, and fatigue. Results suggest adult cancer patients are interested in music therapy, especially music listening. Patient interest and preference were associated with negative affect, anxiety, age, perceived intervention-specific benefits, barriers, and self-efficacy. Findings highlight the need for a comprehensive assessment of patient needs and preferences prior to intervention.

Personality and music preferences: the influence of personality traits on preferences regarding musical elements.

The purpose of this scientific study was to determine how personality traits, as classified by Cattell, influence preferences regarding musical elements. The subject group consisted of 145 students, male and female, chosen at random from different Polish universities. For the purpose of determining their personality traits the participants completed the 16PF Questionnaire (Cattell, Saunders, & Stice, 1957; Russel & Karol, 1993), in its Polish adaptation by Choynowski (Nowakowska, 1970). The participants' musical preferences were determined by their completing a Questionnaire of Musical Preferences (specifically created for the purposes of this research), in which respondents indicated their favorite piece of music. Next, on the basis of the Questionnaire of Musical Preferences, a list of the works of music chosen by the participants was compiled. All pieces were collected on CDs and analyzed to separate out their basic musical elements. The statistical analysis shows that some personality traits: Liveliness (Factor F), Social Boldness (Factor H), Vigilance (Factor L), Openness to Change (Factor Q1), Extraversion (a general factor) have an influence on preferences regarding musical elements. Important in the subjects' musical preferences were found to be those musical elements having stimulative value and the ability to regulate the need for stimulation. These are: tempo, rhythm in relation to metrical basis, number of melodic themes, sound voluminosity, and meter.

Impulsive responding in alcoholics.

BACKGROUND: Impaired decision-making is one diagnostic characteristic of alcoholism. Quantifying decision-making with rapid and robust laboratory-based measures is thus desirable for the testing of novel treatments for alcoholism. Previous research has demonstrated the utility of delay discounting (DD) tasks for quantifying differences in decision-making in substance abusers and normal controls. In DD paradigms subjects choose between a small, immediate reward and a larger, delayed reward. METHODS: We used a novel computerized DD task to demonstrate that abstinent alcoholics (AA, n=14) choose the larger, delayed option significantly less often than control subjects (n=14; p<0.02). This difference in choice tendency was independent of subject age, gender, years of education, or socio-economic status. RESULTS: All subjects discounted as a function of reward delay and amount, with alcoholics demonstrating steeper discounting curves for both variables. This tendency to discount delayed rewards was positively correlated with subjective reports of both alcohol addiction severity (Drug Use Screening Inventory-Revised, Domain 1, p<0.01), and impulsivity (Barratt Impulsivity Scale-11, p<0.004). Novel aspects of this new paradigm include an element of time pressure, an additional experimental condition that evaluated motor impulsivity by assessing the ability to inhibit a pre-potent response, and another control condition to requiring non-subjective choice. CONCLUSIONS: Non-alcoholic controls and alcoholics did not differ on motor impulsivity or non-subjective choice, suggesting that the differing choice behavior of the two groups was due mainly to differences in cognitive impulsivity.

Modeling emotional, cognitive, and behavioral predictors of peer acceptance.

Integrating principles of differential emotions theory and social information-processing theory, this study examined a model of emotional, cognitive, and behavioral predictors of peer acceptance in a sample of 201 early elementary school-age children (mean age = 7 years, 5 months). A path analytic model showed that social skills mediated the effect of emotion knowledge on both same- and opposite-sex social preference, but social skills and verbal ability were more strongly related to opposite-sex peer acceptance. These findings suggest that adaptive social skills constitute a mechanism through which children express their emotion knowledge and achieve peer acceptance. Results also supported findings of previous studies that showed that emotion knowledge mediated the effect of verbal ability on social skills. Findings from the present study have specific implications for emotion-centered prevention programs that aim to improve children's socioemotional competence and enhance the likelihood of peer acceptance.

Introducing uninteresting tasks to children: a comparison of the effects of rewards and autonomy support.

Two experiments compared rewards and autonomy support as methods to promote children's self-regulation for an uninteresting vigilance task. Dependent measures were ratings of positive affect, perception of the task's value, and free-choice engagement. ANOVA results revealed some positive effects associated with autonomy support, whereas no effect for rewards was found in either study. The outcomes of most interest were correlations between free-choice behavior and self-reported measures of affect and value, reflecting the level of integration in self-regulation. As predicted by self-determination theory (Deci & Ryan, 1985, 1991, 2000), rewards were associated with behaviors incongruent from affect and value, whereas autonomy support led to integrated self-regulation. This finding was first detected in Study 1 and later replicated in Study 2. Together, these results point to autonomy support as a beneficial alternative to the common use of rewards.

High self-control predicts good adjustment, less pathology, better grades, and interpersonal success.

What good is self-control? We incorporated a new measure of individual differences in self-control into two large investigations of a broad spectrum of behaviors. The new scale showed good internal consistency and retest reliability. Higher scores on self-control correlated with a higher grade point average, better adjustment (fewer reports of psychopathology, higher self-esteem), less binge eating and alcohol abuse, better relationships and interpersonal skills, secure attachment, and more optimal emotional responses. Tests for curvilinearity failed to indicate any drawbacks of so-called overcontrol, and the positive effects remained after controlling for social desirability. Low self-control is thus a significant risk factor for a broad range of personal and interpersonal problems.

Effects of hypnotic and sleep-inducing drugs on objective assessments of human psychomotor performance and subjective appraisals of sleep and early morning behaviour.

1 An acute dose comparison against placebo of the effects of nitrazepam 5 mg and temazepam 15 and 30 mg on measures of arousal and performance and on subjective assessment of sleep was carried out in 20 subjects with a history of using night-time medication for insomnia. 2 Amylobarbitone (100 mg) was included as an active control and each drug was given in hard gelatin capsules. Subjects reported improved sleep with nitrazepam 5 mg and temazepam 30 mg, but there was evidence of impaired performance the next day with temazepam 30 mg. 3 The effect of temazepam 20 mg prepared in the Scherer formulation was compared against placebo in a further ten subjects. The subjects reported improved sleep without evidence of impaired performance the next day.

The influence of prey experience on movement pattern preference in Salamandra salamandra (L.).

Groups of juvenile Salamandra salamandra were raised selectively with different types of prey. The influence of these conditions on the movement pattern preference was studied during the first six months after metamorphosis. Responses to a black horizontal bar moving continuously or stepwise at step frequencies between 0.25 and 8 steps/s were tested. The differently raised groups showed significant differences in their respective preference for stimulus movement patterns which corresponded with the movement pattern of their food. At the same time, superimposed upon this learning process, a general increase in the relative efficiency of continuous stimulus movement with regard to stepwise stimulus movement could be observed.

The role of early sensory experience in the prey catching responses of Salamandra salamandra to stationary prey.

Two groups of newly metamorphosed Salamandra salamandra (L.) were raised with living and with stationary prey, respectively. One year later, the group which had experience exclusively with stationary prey was significantly better in responding to stationary prey than the group which only had experience with moving prey. This was the case both under light and dark conditions. The experiments show that prey-catching behavior in salamanders can be considerably modified by experience.

"Birds of a feather...": behavioral concordances and preferential personal attraction in children.

The purpose of this study was to assess the extent to which preferential personal attraction was associated with behavioral similarity among newly acquainted children. Participants included 69 focal children, selected from a sample of 236 7-year-old children who met, for the first time, in same-sex quartets (n = 59) for a free-play session. Within each of these quartets, a "discriminating child" was identified; this child expressed a clear preference for one of his or her playmates over one other of her or his quartet playmates. Preference was determined sociometrically after the children became acquainted during free play. The results indicated that "discriminating" children were more behaviorally similar to preferred playmates than to nonpreferred playmates both in terms of cognitive play style and social participation. Implications of the findings are discussed in terms of the relation to the acquaintanceship process.

Can music bring people together? Effects of shared musical preference on intergroup bias in adolescence.

Recent research has successfully applied social identity theory to demonstrate how individuals use music as a basis for intergroup differentiation. The current study investigated how music might also be used to encourage the development of positive intergroup attitudes. Participants (N = 97) were allocated to one of two experimentally created social groups and then led to believe that the groups had similar or different musical preferences. They then evaluated each group and reported their perceptions concerning how they expected their own group to be evaluated by the other group. Participants who believed the groups had similar musical preferences reported more positive intergroup attitudes relative to a control group; they also expected to be evaluated more positively by members of the other group. However, positive intergroup perceptions were also reported by those who believed the two groups had different musical preferences. The implications of these findings for theory and practice are discussed.

News from health research: toward a better understanding.

News about health research findings, especially regarding controversial topics, can seem confusing and conflicting to students and the general public. Many people eventually develop a "turned-off" attitude toward all health news. Yet medical information is one of the key factors involved in health decision-making, because it influences a person's judgment about the potential health impact of a behavior choice. As part of their health education, youngsters need to learn skills to better understand and evaluate reports of research news, so the information available for health decision-making will be more complete and accurate. Such news is already abundant in television, radio, newspaper and magazine reports and will continue to increase as research advances, knowledge expands and health "facts" are revised. This article outlines concepts and skills to help teachers and students understand the changes and controversies in health news. To most effectively use new information generated by medical research, students need to: 1) understand basic concepts about the nature of research and the research process; 2) apply critical thinking approaches to health news; and 3) locate additional health information resources. Generating ways to address these needs is a high priority of the school health education work at the National Heart, Lung and Blood Institute. Comments are invited on this approach.

The evaluation of a Cardiovascular School Health Curriculum: an assessment of long-term cognitive retention and attitudinal correlates.

This study provided evidence that the Cardiovascular School Health Curriculum was successful in increasing the knowledge levels of high school students and maintaining significant portions of that knowledge during a six month period, indicating that with a strong, well developed curriculum, relatively permanent change in knowledge levels can be achieved. This was particularly gratifying to the researchers who believe that the appropriate knowledge of the cardiovascular system, heart diseases and methods of preventing heart and circulatory problems are essential foundations for having positive impact of youths' future behavioral choices. Additional longitudinal studies are planned to augment the findings of this study.

Evidence for an analytic perception of multiharmonic sounds in the bat, Megaderma lyra, and its possible role for echo spectral analysis.

For echolocation, the gleaning bat Megaderma lyra relies on short and broadband calls consisting of multiple harmonic components, each of which is downward frequency modulated. The harmonic components in M. lyra's calls have a relatively small frequency excursion and do not overlap spectrally. Broadband calls of other bat species, on the other hand, often consist of only a few harmonics which are modulated over broad and sometimes overlapping frequency ranges. A call consisting of narrow and nonoverlapping harmonic components may provide a less complete representation of target structure than a call which consists of broadly modulated components. However, a multiharmonic call may help the bats to perceive local spectral changes in the echo from shifts in the peak frequencies of single harmonics, and thereby to extract additional information about the target. To assess this hypothesis, the accuracy with which M. lyra can analyze frequency shifts of single partials in multiharmonic complex tones was investigated. A two-alternative, forced-choice behavioral task was used to measure M. lyra's frequency discrimination threshold for the third partial in complex tones whose spectral composition resembled that of the bat's sonar calls. The discrimination threshold for the third partial in a 21.5-kHz harmonic tone amounted to about 2% and was similar to the bat's pure-tone discrimination threshold at 64.5 kHz. Discrimination performance was essentially unaffected by random frequency changes of the other partials and by reducing stimulus duration from 50.5 to 1.5 ms. Both findings are in accordance with predictions made on the basis of the shape of M. Ivra's cochlear filters. The comparison between the observed frequency discrimination performance and a computational estimate of the expected frequency shift in the third harmonic of an echo reflected by a simple, two-front target showed that M. lyra's frequency resolution is sufficient for analyzing the target-specific information conveyed by shifts in the peak frequency of single echo components.

Sensory acceptability of meat and dairy products and dietary fat in male collegiate swimmers.

This study was undertaken to determine whether high-level training alters food choice behavior with regard to meat and dairy products because of their high fat content. Twenty male collegiate swimmers were compared to 20 male sedentary students for dietary fat intake, nutrition knowledge, and liking of meat and dairy products. There was no significant difference between the two groups for restraint, energy intake, dietary fat intake, and energy derived from fat. Nutrition knowledge, energy derived from saturated fat, and cholesterol intake, however, were significantly higher in the athletes. The two groups did not differ in their hedonic ratings of flavor or in their overall degree of liking of the meat and dairy products, and the athletes actually liked the appearance and texture of the products significantly more than did the sedentary students. This study shows that the sensory appeal of fat-containing animal products is not affected in male swimmers by a high level of exercise.

Broadly tuned spinal neurons for each form of fictive scratching in spinal turtles.

Behavioral choice can be mediated either by a small number of sharply tuned neurons or by large populations of broadly tuned neurons. This issue can be conveniently examined in the turtle spinal cord, which generates each of three forms of scratching-rostral, pocket, and caudal-in response to mechanical stimulation in each of three adjacent regions of the body surface. Previous research showed that many propriospinal neurons are broadly tuned to either the rostral scratch region or the pocket scratch region, but responses to caudal scratch stimulation could not be examined in that reduced preparation. In the current study, individual spinal neurons were recorded extracellularly from the gray matter of the turtle spinal cord hindlimb enlargement, while sites in the rostral, pocket, and caudal scratch regions were mechanically stimulated. Many neurons were broadly tuned to the caudal scratch region; other neurons were broadly tuned to either the pocket scratch or rostral scratch region. All three types were typically found within a single animal. These data are consistent with the hypothesis that the turtle spinal cord relies on large populations of broadly tuned neurons to select each of the three forms of scratching. In addition, neurons that were broadly tuned to each of the scratch regions were typically found in each spinal cord segment and within the same range of mediolateral and dorsoventral locations. Providing that these neurons are related to the selection and generation of the three forms of scratching, this would indicate that cells of this type are not segregated into distinct regions of the spinal cord gray matter.

Use of a concurrent operants paradigm to evaluate positive reinforcers during treatment of food refusal.

The authors evaluated the responsiveness of 4 preschool-aged children to positive reinforcers within a concurrent operants paradigm during mealtimes. The children were presented with two identical, concurrently available sets of food. Each set differed in quantity and quality of positive reinforcement paired with acceptance of each bite of food or in the number of bites of food required to obtain positive reinforcement. Experiment 1 evaluated 1 child's responsiveness to positive reinforcement while permitting escape from bite offers. Experiment 2 evaluated 2 children's responsiveness to positive reinforcement when escape extinction occurred. Results from these experiments suggested that the children were responsive to positive reinforcers and chose more often the bites paired with the greater quantity and/or quality of reinforcement. Experiment 3 evaluated 1 child's responsiveness to positive reinforcement both without and with escape extinction. Results suggested that positive reinforcement affected choice behavior and that escape extinction affected amount of food consumed.
