Caffeinated Soda Intake in Children Is Associated with Neurobehavioral Risk Factors for Substance Misuse
BACKGROUND AND OBJECTIVES: Use of psychotropic substances in childhood has been associated with both impulsivity and other manifestations of poor executive function as well as escalation over time to use of progressively stronger substances. However, how this relationship may start in earlier childhood has not been well explored. Here, we investigated the neurobehavioral correlates of daily caffeinated soda consumption in preadolescent children a…
Initial Validation of a Behavioral Phenotyping Model for Substance Use Disorder
Standard nosological systems, such as DSM-5 or ICD-10, are relied upon as the diagnostic basis when developing treatments for individuals with substance use disorder (SUD). Unfortunately, the vast heterogeneity of individuals within a given SUD diagnosis results in a variable treatment response and/or difficulties ascertaining the efficacy signal in clinical trials of drug development. Emerging precision medicine methods focusing on targeted trea…
Impulsivity and Reflective Thinking in Veterans Seeking Care for Substance Use Disorder
Objective: Substance use disorder (SUD) is a major public health crisis, with increased overdose deaths in the past decade. This has coincided with a tremendous amount of research on those who misuse substances. However, extensive research on SUD vulnerability characteristics such as impulsivity may be complemented by research on theoretically relevant aspects of cognition. The Cognitive Reflection Test (CRT) was designed to measure a person’s ab…
Cognitive effort avoidance in veterans with suicide attempt histories
Suicide attempts (SA) are increasing in the United States, especially in veterans. Discovering individual cognitive features of the subset of suicide ideators who attempt suicide is critical. Cognitive theories attribute SA to facile schema-based negative interpretations of environmental events. Over-general autobiographical memory and facile solutions in problem solving tasks in SA survivors suggest that aversion to expending cognitive effort ma…
Impulsivity and Medical Care Utilization in Veterans Treated for Substance Use Disorder
Background Impulsivity has been defined by acting rashly during positive mood states (positive urgency; PU) or negative mood states (negative urgency; NU) and by excessive de-valuation of deferred rewards. These behaviors reflect a “live in the now” mentality that is not only characteristic of many individuals with severe substance use disorder (SUD) but also impedes medical treatment compliance and could result in repeated hospitalizations or ot…
Social Information Processing in Substance Use Disorders
Positive social connections are crucial for recovery from Substance Use Disorder (SUD). Of interest is understanding potential social information processing (SIP) mediators of this effect. To explore whether persons with different SUD show idiosyncratic biases toward social signals, we administered an emotional go-nogo task (EGNG) to 31 individuals with Cocaine Use Disorder (CoUD), 31 with Cannabis Use Disorder (CaUD), 79 with Opioid Use Disorder…
The Impact of Parental Incarceration on Psychopathy, Crime, and Prison Violence in Women
There is a growing interest in understanding the consequences of parental incarceration. Unfortunately, research exploring the long-term criminological and personality effects in female offspring is limited, particularly among second-generation female offenders. In a sample of 170 female offenders, we first assessed the correlations between psychopathy facets, prison violence, and types of crime. Next, we tested the association between childhood …
The Adolescent Brain Cognitive Development (ABCD) study
The ABCD study is recruiting and following the brain development and health of over 10,000 9-10 year olds through adolescence. The imaging component of the study was developed by the ABCD Data Analysis and Informatics Center (DAIC) and the ABCD Imaging Acquisition Workgroup. Imaging methods and assessments were selected, optimized and harmonized across all 21 sites to measure brain structure and function relevant to adolescent development and add…
Familial Transmission of Continuous Performance Test Behavior
Continuous Performance Tests (CPTs) provide information on attentional processing and impulsive behavior. The results of previous research that used self-report measures have provided evidence for familial transmission (through genetic and/or environmental influences) of impulsive characteristics. The authors of the present study examined whether the impulsive behavioral parameters that are measured by the CPT also share familial relationships. T…
Effects of menstrual cycle phase on aggression measured in the laboratory
This study investigated the effects of menstrual cycle phase on aggression in two groups of women, which differed in the severity of their self-reported perimenstrual symptoms. A low- and a high-symptom group were recruited using the Menstrual Distress Questionnaire (MDQ) to define the groups. Twenty-two subjects (11 low and 11 high symptom) participated across one menstrual cycle: during the premenstrual, menstrual, midfollicular, and ovulatory …
Self-Reported Impulsivity is Correlated with Laboratory-Measured Escape Behavior
Aggression has been previously correlated with impulsive personality. In the present study, Barratt Impulsiveness Scale (BIS) scores of 40 male controls aged 15-40 years were related to the frequency of free-operant aggressive and escape responses toward a fictitious antagonist. Participants earned "points" worth money with repeated button presses on a fixed-ratio schedule and were provoked by the periodic subtraction of a point. These subtractio…
