Pathways of Risk for Accelerated Heavy Alcohol Use Among Adolescent Children of Alcoholic Parents

The current study examined two questions. First, do internalizing symptoms and externalizing behavior each mediate the relations between parent psychopathology (alcoholism, antisocial personality disorder, and affective disorder) and growth in adolescent heavy alcohol use? Second, are there gender differences in these mediated pathways? Using latent curve analyses, we examined these questions in a high-risk sample of 439 families (53% children of alcoholic parents; 47% female). Collapsing across gender, adolescent-reported externalizing behavior mediated both the relation between parent alcoholism and growth in heavy alcohol use and the relation between parent antisociality and growth in heavy alcohol use. Parent-reported externalizing behavior only mediated the relation between parent antisociality and growth in heavy alcohol use in males. No support was found for internalizing symptoms as a mediator of these relations. Avenues are suggested for further exploring and integrating information about different mediating processes accounting for children of alcoholics' risk for heavy alcohol use.     

Learning to control brain activity: a review of the production and control of EEG components for driving brain-computer interface (BCI) systems

Brain-computer interface (BCI) technology relies on the ability of individuals to voluntarily and reliably produce changes in their electroencephalographic (EEG) activity. The present paper reviews research on cognitive tasks and other methods of generating and controlling specific changes in EEG activity that can be used to drive BCI systems. To date, motor imagery has been the most commonly used task. This paper explores the possibility that other cognitive tasks, including those used in imaging studies, may prove to be more effective. Other factors which influence performance are also considered in relation to selection of tasks, as well as training of subjects.     

Heterosexist discrimination and relational sacrifice of same-sex couples

Drawing on the family stress process model and using data from 141 same-sex couples (N = 282 partners), we examined associations between heterosexist discrimination and relational sacrifices (i.e., willingness and behaviors). We also examined the moderating roles of both partners' internalized homophobia and state-level liberalism on same-sex marriage legalization. Actor-partner interdependence moderation models were conducted. Most of our findings supported hypotheses from the family stress process model. One individual's experiences of greater heterosexist discrimination were related to the partner's higher levels of sacrifice willingness and the individual's own higher frequency of sacrifice behaviors. Such associations emerged (a) among couples living in more liberal states that legalized same-sex marriage earlier, and (b) when the individual's partner reported lower levels of internalized homophobia. Yet the moderating role of an individual's internalized homophobia was the opposite of our hypothesis. When individuals reported high (versus low) internalized homophobia, individuals' experiences of more discriminative events were related to partners' higher levels of sacrifice willingness. Collectively, our study findings highlight that—when investigating how same-sex couples forge and maintain romantic bonds—researchers should consider their experiences in the social cultural context of heteronormativity, which includes the focus on discrimination, stigma, and affirmative laws and policies.     

Understanding marital conflict 7 years later from prenatal representations of marriage

We examine how representations of marriage, assessed prenatally, predict different types of marital conflict (cooperation, avoidance/capitulation, stonewalling, and child involvement in parental conflict) at 7 years postpartum (N=132 individuals). We assessed representations of marriage prenatally by interviewing spouses about their own parents' marriage, and then rated the content and insightfulness of their memories. Results show that marital representations characterized by higher insight predict higher cooperation and lower child involvement in parental conflict, whereas content of marital representations was not a significant predictor of marital conflict. Further, individuals who remember negative memories from their parents' marriage with high insight were lowest on child involvement in parental conflict, whereas those who remember negative memories with low insight were highest on child involvement in parental conflict. Finally, women who remember negative content with high insight report the highest cooperation, whereas women who remember negative content with low insight report the lowest cooperation. For men, however, marital representations were less effective in predicting later cooperation. We conclude that marital representations, even when assessed prenatally, influence certain types of marital conflict 7 years later. Using such findings, therapists could help spouses gain insight into how the memories of their parents' marriage relate to the use of specific conflict strategies in their marriage.     

Mind the gap: the lack of common language in healthcare ethics

Ethics consultation services provide support to staff, patients, and family members who find themselves in morally difficult situations in healthcare settings. Not unlike other clinical consultation services, ethics consultation activities should be well documented. Good documentation allows for evaluation of the consultation process and the ability to refer back to consults when needed, and provides data for future research in healthcare ethics (HCE). In our exploration of existing HCE documentation systems, we identified two main points of interest. First, HCE information documentation systems are powerful tools for providing information on ethics consultation services.These documentation systems can be used to produce detailed reports on various HCE activities both institutionally and cross-institutionally. Second, our findings indicate greater agreement in the language and terminology of HCE needs to be established. Cultivation of such common language is needed in order to develop a standard healthcare ethicists can use to document and categorize consults. Standardization of language would allow data to be readily comparable and lead to more consistency in documentation of ethics consultations. Ultimately, standardization of documentation can also constitute a standard of practice for HCE in general.The development of such standards is essential for any developing profession, and will be required for HCE as it moves in towards professionalization in Canada.     

Testing Whether and When Parent Alcoholism Uniquely Affects Various Forms of Adolescent Substance Use

The current study examined the distal, proximal, and time-varying effects of parents’ alcohol-related consequences on adolescents’ substance use. Previous studies show that having a parent with a lifetime diagnosis of alcoholism is a clear risk factor for adolescents’ own substance use. Less clear is whether the timing of a parent’s alcohol-related consequences differentially predicts the adolescent’s own substance involvement. Using a multilevel modeling approach, we tested whether adolescents showed elevated rates of alcohol, heavy alcohol, marijuana and other illegal drug use (a) at the same time that parents showed alcohol-related consequences (time-varying effects), (b) if parents showed greater alcohol-related consequences during the child’s adolescence (proximal effects), and (c) if parents had a lifetime diagnosis of alcoholism that predated the child’s adolescence (distal effects). We tested these effects in a high-risk sample of 451 adolescents assessed over three waves beginning at ages 11–15 from 1988 to 1991 (53?% male, 71?% non-Hispanic Caucasian, 54?% children of alcoholic parents and 46?% matched controls). Strong and consistent distal effects of parent alcoholism on adolescent’s substance use were found, though no additional risk was associated with proximal effects. Limited time-varying effects were also found. The importance of differentiating the timing effects of parent alcoholism in identifying underlying mechanisms of risk for adolescent substance use is discussed.     

Crime in Atlantic City: Do casinos make a difference?

In November, 1976 a constitutional referendum in the state of New Jersey legalized casino gaming. This paper examines the impact of this action on crime in Atlantic City, the only location in the state where gambling is permitted. More specifically, the analysis looks at the incidence of FBI index crimes in that jurisdiction in two basic ways. First, the work examines the raw numbers and rate of crime in the city, both before and after the introduction of casino gambling. Although the analysis establishes that the raw figures show that there has been a significant increase in index crimes, it is argued that using these statistics as a measure of crime in Atlantic City is misleading because they fail to take into account the numerous visitors to the city when calculating the population‐at‐risk and because they do not differentiate between crime that occurs in the community and that which occurs in the casinos. The second phase of the analysis addresses these issues through the use of adjusted populations and data that identify casino‐based versus non‐casino crimes. This analysis leads us to conclude that the legalization of gambling has not resulted in a significant increase in index crimes in Atlantic City.     

A defense of the subordinate-level expertise account for the N170 component

A recent paper in this journal reports two event-related potential (ERP) experiments interpreted as supporting the domain specificity of the visual mechanisms implicated in processing faces (Cognition 83 (2002) 1). The authors argue that because a large neurophysiological response to faces (N170) is less influenced by the task than the response to objects, and because the response for human faces extends to ape faces (for which we are not expert), we should reject the hypothesis that the face-sensitivity reflected by the N170 can be accounted for by the subordinate-level expertise model of object recognition (Nature Neuroscience 3 (2000) 764). In this commentary, we question this conclusion based on some of our own ERP work on expert object recognition as well as the work of others.     

Motor sequence learning and reading ability: is poor reading associated with sequencing deficits?

Although it is widely assumed that children with learning disabilities have "sequencing problems," these have not been well specified. A non-verbal serial reaction time (SRT) paradigm was used to evaluate motor sequence learning in 422 children between ages 7 and 11 in relation to reading, cognitive ability level, and attention problems. The children demonstrated the response profile typically associated with motor sequence learning, but the component of the profile indicative of implicit sequence learning was not reliably associated with any of the predictors. Cognitive ability predicted overall response time; cognitive ability, reading, and attention problems each predicted overall accuracy. Explicit learning was predicted by cognitive ability, but not by reading or attention problems. Thus, we found no evidence that poor reading is preferentially associated with a domain general deficit in sequential learning.     

SCALING THE EPISODIC FAMILIARITIES OF PICTURES AND WORDS

Abstract— Most current memory theories assume that judgments of past occurrence are based on a unidimensional familiarity signal In a test of this hypothesis, subjects studied mixed lists of pictures and words that occurred up to three times each They then were given two tests a forced-choice frequency discrimination test including all pairs of conditions (e g., picture seen twice vs word never seen) and a numerical frequency judgment test on individual items Forced-choice proportions for all pairings (picture-picture, word-word, and picture-word) were well fit by a one-dimensional scaling solution, suggesting a common basis of recognition and frequency judgments for both pictures and words Both forced-choice and numerical judgment data indicated that familiarities of pictures started lower than those of words but increased more rapidly with repetition Results are discussed in connection with the distinction between familiarity and recall, and the possible role of rescaling in the mirror effect.
