Development of frontal electroencephalogram (EEG) and heart rate (ECG) responses to affective musical stimuli during the first 12 months of post-natal life

We examined the development of infants' regional electrocortical (EEG) and heart rate (ECG) responses to affective musical stimuli during the first 12 months of post-natal life. Separate groups of infants were seen at 3 (n=33), 6 (n=42), 9 (n=52), and 12 (n=40) months of age at which time regional EEG and ECG responses were continuously recorded during a baseline condition and during the presentation of three orchestral pieces that were known to vary in affective valence and intensity (happy, sad, fear). Overall, there were two important findings. First, we found that although the overall amount of EEG 4-8 Hz power increased between 3 and 12 months, the distribution of EEG power changed across age, with the younger infants (3- and 6-month-olds) showing no difference between frontal and parietal regions, but the older infants (9- and 12-month-olds) showing relatively more activation at frontal than at parietal sites. This development likely reflects the maturation of frontal lobe function. Second, we found that the presentation of affective music significantly increased brain activity at 3 months of age, had seemingly little effect at 6 and 9 months, and significantly attenuated brain activity at 12 months. Findings suggest that there is a clear developmental change in the effect of music on brain activity in the first year, with music having a "calming" influence on infants by the end of the first year of life.     

Gender Differences in Adolescent Depression: Gender-Typed Characteristics or Problem-Solving Skills Deficits?

This study explored gender differences indepressive symptoms during adolescence in relation withgender-typed characteristics, problem-solving abilities,and stressful life events. Participants were 306 white French-speaking adolescents (142 men and164 women) from upper middle-class families enrolled ina high school in the Trois-Rivières area ofQuebec. Participants ranged in age from 14 to 17 years, with a mean age of 15.3 years (SD = .95). Theycompleted the French versions of the Beck DepressionInventory (BDI), the Bem Sex Role Inventory (BSRI), theProblem-Solving Inventory (PSI), and the Life Event Questionnaire (LEQ) during a regularclass. Depressed participants distinguished themselvesfrom nondepressed participants on all variables exceptfor expressivity. Instrumentality was negatively correlated with depression for boys and for thetotal sample. Scores on all three subscales of the PSIcorrelated with depression, and with scores on the LEQ,with the exception of In the Last Yearsubscale for boys. A path analysis was conducted usingscores on the BDI as the dependent variable. Subjectiveproblem-solving abilities act as a mediating variablebetween instrumentality and depression. Instrumentality, expressivity, and problem-solving abilitiesexplained a significant portion of the variance of theBDI.     

Effects of High-Probability Request Sequences on Preschoolers' Compliance and Disruptive Behavior

A high-probability request sequence was implemented with three preschool children with developmental delays within their classroom during typical activities. A multiple baseline design across subjects was used to evaluate the effects of the high-probability request sequence on compliant responding to low-probability requests and the occurrence of disruptive behavior. Results of the study indicate that the use of the high-probability request sequence was effective in increasing compliant responding to low-probability requests delivered by two different trainers for all children. No increases in disruptive behavior were noted as a result of using the high-probability request sequence. When the high-probability request sequence was withdrawn, compliant responding to low-probability requests was maintained for all children across time and in different settings.     

Scientific societies and whistleblowers: the relationship between the community and the individual

Formalizing shared ethical standards is an activity of scientific societies designed to achieve a collective goal of promoting ethical conduct. A scientist who is faced with the choice of becoming a “whistleblower” by exposing misconduct does so in the context of these ethical standards. Examination of ethics policies of scientific societies which are members of the Council of Scientific Society Presidents (CSSP) shows a breadth of purpose and scope in these policies. Among the CSSP member societies, some ethics policies chiefly present the ethical culture of the community in an educational context and do not have enforcement procedures. Other policies are more comprehensive and include standards for certification, procedures for addressing ethical issues, and established sanctions. Of the 36 member societies of CSSP that have developed a code or adopted a code of another professional society, 18 specifically identified a responsibility to expose ethical misconduct, demonstrating an acknowledgment of the possible critical role of the whistleblower in addressing ethical issues. Scientific societies may revise their ethics codes based upon experience gained in addressing cases of ethical misconduct. In most cases, the action of a whistleblower is the initial step in addressing an ethics violation; the whistleblower may either be in the position of an observer or a victim, such as in the case of someone who discovers that his or her own work has been plagiarized. The ethics committee of a scientific society is one of several possible outlets through which the whistleblower can voice a complaint or concern. Ethical violations can include falsification, fabrication, plagiarism and other authorship disputes, conflict of interest and other serious violations. Commonly, some of these violations may involve publication in the scientific literature. Thus addressing ethical issues may be intertwined with a scientific society’s role in the dissemination of new scientific results. For a journal published by a scientific society, the editor can refer at some point to the ethics committee of the society. Whereas, in the case of a journal published by a commercial publisher, the editor may be without direct support of the associated scientific community in handling the case. The association of a journal with a scientific society may thus direct a whistleblower towards addressing the issue within the scientific community rather than involving the press or talking to colleagues who may gossip. A formal procedure for handling ethics cases may also discourage false accusers. Another advantage of handling complaints through ethics committees is that decisions to contact home institutions or funding agencies can be made by the ethics committee and are not the responsibility of the whistleblower or the editor of the journal. The general assessment is that the establishment of ethics policies, especially policies covering publication in society journals, will promote a culture supportive of whistleblowers and discouraging to false accusers. An earlier version of this paper was presented at the symposium entitled “Damned If You Do, Damned If You Don’t: What the Scientific Community Can Do About Whistleblowing” held during the Annual Meeting of the American Association for the Advancement of Science, Seattle, Washington, 15 February, 1997.     

Family-expressed emotion,childhood-onset depression,and childhood-onset schizophrenia spectrum disorders: Is expressed emotion a nonspecific correlate of child psychopathology or a specific risk factor for depression?

Expressed emotion (EE) was examined, using the brief Five Minute Speech Sample measure, in families of (1) children with depressive disorders, (2) children with schizophrenia spectrum disorders, and (3) normal controls screened for the absence of psychiatric disorder. Consistent with the hypothesis of some specificity in the association between EE and the form of child disorder, rates of EE were significantly higher among families of depressed children compared to families of normal controls and families of children with schizophrenia spectrum disorders. Within the depressed group, the presence of a comorbid disruptive behavior disorder was associated with high levels of critical EE, underscoring the need to attend to comorbid patterns and subtypes of EE in future research.This research was supported by a grant from the John D. and Catherine T. MacArthur Foundation as part of their Network on Risk and Protective Factors in the Major Mental Disorders. The authors wish to express their appreciation to Sybil Zaden and Ana Magana-Amato for their assistance coding the FMSS-EE data, to Gwen Gordon for her assistance with data analysis, and to the families participating in the project.     

Pascal external functions for Strawberry Tree’s “Analog Connection Workbench” on the Macintosh

Strawberry Tree Incorporated is one of several manufacturers of input-output boards for the Macintosh computer. The Analog Connection Workbench program (Strawberry Tree Inc.) provides an icon-based programming system for these input-output boards that has most of the functions that are necessary to implement behavioral experiments. However, experimental psychologists may frequently encounter needs that the Workbench program cannot easily meet. Because the Workbench is programmed in C, whereas many psychologists are more expert in programming in Pascal, we describe, in tutorial fashion, how the user may define new external functions in Pascal on the Macintosh and integrate these functions into the icon-based Workbench programming system.     

Undermining Effects of the Foot-in-the-Door Technique with Extrinsic Rewards

The self-perception explanation of the foot-in-the-door technique suggests that a person who complies with a small request infers that he or she is the kind of generous individual who is more likely to comply with a larger demand. It was hypothesized that individuals who are promised a monetary reward for their compliance with a small request are not more likely to comply with a larger demand because they cannot perceive themselves as generous persons. To test this hypothesis, subjects were presented with a small request (a 5-minute telephone interview) followed, 2 or 3 days later, by a larger demand (a 25-minute telephone interview). Some of the subjects were promised a monetary reward for their compliance with a small request (pay condition) while others were not promised a reward (no-pay condition). Results showed that rate of compliance in the no-pay conditon (64.3%) was significantly higher than rate of compliance in either a no-initial-request control condition (45.0%) or the pay condition (33.3%). The difference in rate of compliance between the control condition and the pay condition was not significant.     

Cross-sectional,longitudinal and composite longitudinal data on the Career Maturity Inventory Attitude Scale

Longitudinal data collection designs are frequently used in the study of developmental variables but typically yield patterns of results that are different from those obtained using cross-sectional designs. Recent research has focused on ways to clarify and reconcile the methodological distinctions between these two designs by utilizing alternative designs that incorporate features of both. This investigation compared the results obtained by the two traditional designs on the Career Maturity Inventory-Attitude Scale with the effects of an alternative design: constructing a composite longitudinal gradient. The two traditional methodologies yielded different results from each other for males, but not for females. However, the alternative design failed to eliminate the obtained differences for males, and introduced differences for females, casting doubt on the efficacy of the “solution.” The implications of these results for developmental research and career maturity were discussed.
