Abstract
BACKGROUND Emotional reactivity is an important construct to consider when studying mental disorders. This study was conducted to translate and assess the factor structure, construct validity and internal consistency of a German version of the Emotion Reactivity Scale (ERS), which is an originally English questionnaire assessing three components of emotional reactivity: sensitivity, intensity and persistence of emotions. METHODS The German ERS and a range of questionnaires used to assess convergent and discriminant validity were completed by 334 German speaking Swiss participants. RESULTS Confirmatory factor analysis showed strong support for a bi-factor model, with evaluation indices pointing to a unidimensional construct rather than to domain specific factors. The questionnaire showed good reliability and the factor structure was similar across gender. The ERS showed convergent validity with general psychopathology, behavioral inhibition, negative affect, orienting sensitivity, depressive symptoms and symptoms of disordered eating, and discriminant validity with behavioral activation and alcohol consumption. CONCLUSIONS Findings support the construct validity of the German ERS and suggest that it assesses a unidimensional construct with high internal consistency. Accounting for the unidimensional nature of the scale and aiming for efficient assessment tools, future research could, based on these findings, develop and evaluate the psychometric properties of a short version of the ERS.

Assessing negative affect in mice during abstinence from alcohol drinking: Limitations and future challenges. Alcohol 2022; 100:41-56. [PMID: 35181404 PMCID: PMC8983487 DOI: 10.1016/j.alcohol.2022.02.001] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 02/09/2022] [Accepted: 02/09/2022] [Indexed: 01/09/2023]
Abstract
Alcohol use disorder (AUD) is frequently comorbid with mood disorders, and these co-occurring neuropsychiatric disorders contribute to the development and maintenance of alcohol dependence and relapse. In preclinical models, mice chronically exposed to alcohol display anxiety-like and depressive-like behaviors during acute withdrawal and protracted abstinence. However, in total, results from studies using voluntary alcohol-drinking paradigms show variable behavioral outcomes in assays measuring negative affective behaviors. Thus, the main objective of this review is to summarize the literature on the variability of negative affective behaviors in mice after chronic alcohol exposure. We compare the behavioral phenotypes that emerge during abstinence across different exposure models, including models of alcohol and stress interactions. The complicated outcomes from these studies highlight the difficulties of assessing negative affective behaviors in mouse models designed for the study of AUD. We discuss new behavioral assays, comprehensive platforms, and unbiased machine-learning algorithms as promising approaches to better understand the interaction between alcohol and negative affect in mice. New data-driven approaches in the understanding of mouse behavior hold promise for improving the identification of mechanisms, cell subtypes, and neurocircuits that mediate negative affect. In turn, improving our understanding of the neurobehavioral basis of alcohol-associated negative affect will provide a platform to test hypotheses in mouse models that aim to improve the development of more effective strategies for treating individuals with AUD and co-occurring mood disorders.

Acta Psychol (Amst) 2021; 220:103427.

Abstract
The startle reflex has been suggested to operate as a psychophysiological marker of psychopathic personality, based on findings from studies using a range of different methodologies and participant samples. The present review aims at synthesizing existing evidence of the relationship between psychopathy and the startle reflex across task paradigms, psychopathic personality subtypes and subdimensions, participant samples (i.e., incarcerated/ clinical or non-offenders), and age groups using the triarchic model of psychopathy as a frame of reference. Systematic literature searches were conducted up until the 24th of March 2020 in PubMed, PsycINFO, and Web of Science. A total of 2311 potential studies were identified, out of which 40 met relevancy and quality criteria. Results indicate that reduced aversive startle potentiation is associated with psychopathic personality in general, but clusters of traits relating to the triarchic model constructs of boldness and meanness in particular. Available evidence suggest that startle paradigms could be meaningful for differentiating individuals with and without psychopathic personality. Findings support suggestions of psychopathic personality as a multifaceted, rather than a unitary construct. Reduced aversive startle potentiation has also been found in relation to psychopathic features in child-aged samples but work of this kind is limited and more research is needed. Future studies should focus on greater consistency in task paradigms and analytic strategies to enhance the capacity to compare and integrate findings across studies.

Abstract
Sexual minorities (e.g. lesbian, gay, bisexual) are at increased risk for alcohol use disorder (AUD) compared to heterosexuals. The minority stress model postulates that disparities in AUD stem, in part, from stress specific to sexual minorities (e.g. heterosexism). However, little research has examined psychophysiological markers of minority stress reactivity and how psychophysiological stress reactivity is associated with lifetime minority stress and alcohol use among sexual minorities. Emotion modulation of the startle response is a well-established paradigm for capturing psychophysiological stress reactivity under controlled laboratory conditions. Purpose: This preliminary study is the first to use the startle experimental paradigm to examine psychophysiological reactivity to stigma among sexual minorities. Procedures: Sexual minority participants (N = 20; 55% female), aged 18 to 27 years (M = 21.80, SD = 2.65), were recruited from the community. We compared startle reactivity in response to three types of stimuli (stigma, negative, and neutral) among heavy drinking sexual minority young adults. Although statistically underpowered, we also explored the associations between startle reactivity and self-reported drinking behaviors and lifetime minority stress. Results: Both stigma and general unpleasant stimuli produced more psychophysiological stress reactivity than neutral stimuli among sexual minorities. Psychophysiological stress reactivity was correlated with greater quantity of drinks reported on drinking days in the past month, but not greater frequency. Additionally, lifetime exposure to minority stress was associated with a blunted reactivity to stigma stimuli. Conclusions: These findings provide methodological advances and important implications for minority stress theory and alcohol use among sexual minorities.

Appetitive startle modulation in the human laboratory predicts Cannabis craving in the natural environment. Psychopharmacology (Berl) 2018; 235:1933-1943.

Abstract
RATIONALE Drug-related cues evoke craving and stimulate motivational systems in the brain. The acoustic startle reflex captures activation of these motivational processes and affords a unique measure of reactivity to drug cues. OBJECTIVES This study examined the effects of cannabis-related cues on subjective and eye blink startle reactivity in the human laboratory and tested whether these effects predicted youth's cue-elicited cannabis craving in the natural environment. METHODS Participants were 55 frequent cannabis users, ages 16 to 24 years (M = 19.9, SD = 1.9; 55% male; 56% met criteria for cannabis dependence), who were recruited from a clinical trial to reduce cannabis use. Eye blink electromyographic activity was recorded in response to acoustic probes that elicited startle reactivity while participants viewed pleasant, unpleasant, neutral, and cannabis picture cues. Following the startle assessment, participants completed an ecological momentary assessment protocol that involved repeated assessments of cue-elicited craving in real time in their real-world environments. RESULTS Multilevel models included the presence or absence of visible cannabis cues in the natural environment, startle magnitude, and the cross-level interaction of cues by startle to test whether cue-modulated startle reactivity in the laboratory was associated with cue-elicited craving in the natural environment. Analyses showed that cannabis-related stimuli evoked an appetitive startle response pattern in the laboratory, and this effect was associated with increased cue-elicited craving in the natural environment, b = - 0.15, p = .022, 95% CI [- 0.28, - 0.02]. Pleasant stimuli also evoked an appetitive response pattern, but in this case, blunted response was associated with increased cue-elicited craving in the natural environment, b = 0.27, p < .001, 95% CI [0.12, 0.43]. CONCLUSIONS Our findings support cue-modulated startle reactivity as an index of the phenotypic expression of cue-elicited cannabis craving.

Abstract
AIMS It is well known that impulsivity is a risk factor for the development of Addictive Disorders, and more specifically Alcohol Use Disorders (AUD). Recently, the Startle-Response Based Tasks (SRBT) and its different forms of plasticity have been found to be impaired in the alcoholic population. This is the first study to explore the correlation between impulsivity laboratory tasks and the SRBT test, in order to determine whether impulsivity and startle response (SR) could be related and in turn, explain their association with Alcohol Dependence (AD). METHODS SUBJECTS 40 men, who met DSM-IV criteria for AD and had been abstinent for at least one month. Impulsivity was assessed using three laboratory tests: Continuous Performance Test (CPT), Stop-Signal Task (SST) and Differential Reinforcement for Low-Rate Responding (DRL6). Patients also underwent the SR test. They were compared to 40 matched controls. RESULTS Impulsivity laboratory measures tasks (SST and commissions of the CPT) correlated positively with the magnitude of SR (P < 0.05) and with habituation (P < 0.05). Scores on DRL6 correlated negatively with the magnitude of SR (P < 0.05). This was not found in the control group. CONCLUSIONS The fact that impulsivity laboratory measures and the SR are correlated in patients but not in controls, could imply the existence of a common link for these two measures in alcoholic patients. Our findings support the hypothesis of the existence of two different vulnerability pathways for the development of AUD: anxiety and disinhibitory behaviour.

Abstract
AIMS Little is known about changes in the modulation of the startle reflex when patients go through an alcohol-dependence treatment in an outpatient facility. In the current study, the affective modulation of the cue-related startle reflex has been used to evaluate changes in the emotional processing of alcohol-related stimuli that occurred after a standard cognitive-behavioral intervention, and to assess the outcome of this intervention. We hypothesized a 'normalization' of the startle inhibition for the alcohol-related cues during the period of treatment. We also assumed that higher startle inhibition at baseline elicited by alcohol cues would predict the relapse on alcohol consumption during treatment. PARTICIPANTS A total of 98 alcohol-dependent subjects were included who fulfilled DSM-IV criteria for alcohol dependence. A control group of 72 subjects was selected to match demographic characteristics. MEASUREMENTS All patients received a standard cognitive-behavioral therapy once a week throughout the study period. FINDINGS Results show that the startle response differed significantly after 12 weeks of treatment for alcohol-related, neutral and aversive stimuli between alcohol-dependent patients and controls. Low startle responses at baseline to alcohol cues predicted relapse. CONCLUSIONS These results may indicate that the startle reflex is referred to enduring and permanent processes of cue reactivity, and that the emotional processing of alcohol-associated cues assessed with the affect-modulated startle reflex is less altered by interventions attempting to influence explicit cognitions. Furthermore, lower values of the baseline startle reflex elicited by alcohol-associated stimuli were associated with higher probability of relapse on alcohol use.

Abstract
Cue modulation of the startle reflex is a paradigm that has been used to understand the emotional mechanisms involved in alcohol dependence. Attenuation of the startle reflex has been demonstrated when alcohol-dependent subjects are exposed to alcohol-related stimuli. However, the role of clinical variables on the magnitude of this response is unknown. The objective of this study was to determine the relationship between a number of clinical variables-severity of alcoholism, family history of alcoholism (FHA+), personality traits related to the sensitivity to reward-and the startle reflex response when subjects with alcohol dependence were viewing alcohol-related cues. After detoxification, 98 participants completed self-report instruments and had eye blink electromyograms measured to acoustic startle probes [100-millisecond burst of white noise at 95 dB(A)] while viewing alcohol-related pictures, and standardised appetitive, aversive and neutral control scenes. Ninety-eight healthy controls were also assessed with the same instruments. There were significant differences on alcohol-startle magnitude between patients and controls. Comparisons by gender showed that women perceived alcohol cues and appetitive cues more appetitive than men. Male and female patients showed more appetitive responses to alcohol cues when compared with their respective controls. Our patients showed an appetitive effect of alcohol cues that was positively related to severity of alcohol dependence, sensitivity to reward and a FHA+. The data confirmed that the pattern of the modulation of the acoustic startle reflex reveals appetitive effects of the alcohol cues and extended it to a variety of clinical variables.

Abstract
Alcoholic patients who have undergone multiple detoxifications/relapses show altered processing of emotional signals. We performed functional magnetic resonance imaging during performance of implicit and explicit versions of a task in which subjects were presented with morphs of fearful facial emotional expressions. Participants were abstaining, multiply detoxified (MDTx; n=12) or singly detoxified patients (SDTx; n=17), and social drinker controls (n=31). Alcoholic patients were less able than controls to recognize fearful expressions, and showed lower activation in prefrontal areas, including orbitofrontal cortex and insula, which mediate emotional processing. The decrease in activation was greater in MDTx patients who also showed decreased connectivity between insula and prefrontal areas, and between amygdala and globus pallidus. In the explicit condition, the strength of connectivity between insula and areas involved in regulation of emotion (inferior frontal cortex and frontal pole) was negatively correlated with both the number of detoxifications and dependency (measured by the severity of alcohol dependency (SADQ) and control over drinking score (Impaired Control questionnaire, ICQ)). In contrast, increased connectivity was found between insula and the colliculus neuronal cluster, and between amygdala and stria terminalis bed nucleus. In the implicit condition, number of detoxifications and ICQ score correlated positively with connectivity between amygdala and prefrontal cortical areas involved in attentional and executive processes. Repeated episodes of detoxification from alcohol are associated with altered function both in fear perception pathways and in cortical modulation of emotions. Such changes may confer increased sensitivity to emotional stress and impaired social competence, contributing to relapse.

Abstract
Both physiological and behavioral studies provide evidence to suggest that deficits in frontal cortical control circuits may contribute to the risk for developing alcohol dependence. Event-related potential (ERP) and eye blink responses to startle and short delay prepulse-plus-startle stimuli, and psychiatric diagnoses were investigated in young adult (age 18-30 years) men (n=135) and women (n=205) Mexican Americans. Women displayed a significant increase in the amplitude of the eye blink response to both the startle and pre-pulse-plus-startle stimuli. None of the psychiatric diagnoses were associated with differences in eye blink responses. ERP responses to the startle and prepulse-plus startle stimuli included a negative polarity wave at approximately 400 ms that was of the highest amplitude in the frontal leads (N4S). Women were found to have significantly higher amplitude N4S responses than men. Participants with alcohol dependence demonstrated significantly less inhibition and more facilitation of the N4S component by the pre-pulse stimuli. This finding was not associated with a diagnosis of: any other drug dependence disorder (including nicotine), anxiety or affective disorder, or conduct/antisocial personality disorder. The present study suggests that gender and a lifetime diagnosis of alcohol dependence may selectively contribute to this frontal late wave electrophysiological response to prepulse-plus-startle stimuli.

Abstract
The Antisocial personality disorder (ASPD), one of the most common co-morbid psychiatric disorders in heroin-dependent patients, is associated with a lack of affective modulation. The present study aimed to compare the affect-modulated startle responses of opioid-maintained heroin-dependent patients with and without ASPD relative to those of healthy controls. Sixty participants (20 heroin-dependent patients with ASPD, 20 heroin-dependent patients without ASPD, 20 healthy controls) were investigated in an affect-modulated startle experiment. Participants viewed neutral, pleasant, unpleasant, and drug-related stimuli while eye-blink responses to randomly delivered startling noises were recorded continuously. Both groups of heroin-dependent patients exhibited significantly smaller startle responses (raw values) than healthy controls. However, they showed a normal affective modulation: higher startle responses to unpleasant, lower startle responses to pleasant stimuli and no difference to drug-related stimuli compared to neutral stimuli. These findings indicate a normally modulated affective reactivity in heroin-dependent patients with ASPD.

Abstract
Heroin dependence (HD) is a chronic relapsing brain disorder characterized by a compulsion to seek and use heroin. Stress is seen as a key factor for heroin use. Methadone maintenance and the prescription of pharmaceutical heroin [diacetylmorphine (DAM)] are established treatments for HD in several countries. The present study examined whether DAM-maintained patients and methadone-maintained patients differ from healthy controls in startle reflex and cortisol levels. Fifty-seven participants, 19 of each group matched for age, sex and smoking status, completed a startle session which included the presentation of 24 bursts of white noise while eye-blink responses to startling noises were recorded. Salivary cortisol was collected three times after awakening, before, during and after the startle session. DAM was administered before the experiment, while methadone was administered afterwards. Both heroin-dependent patient groups exhibited significantly smaller startle responses than healthy controls (P < 0.05). Whereas the cortisol levels after awakening did not differ across the three groups, the experimental cortisol levels were significantly lower in DAM-maintained patients, who received their opioid before the experiment, than in methadone-maintained patients and healthy controls (P < 0.0001). Opioid maintenance treatment for HD is associated with reduced startle responses. Acute DAM administration may suppress cortisol levels, and DAM maintenance treatment may represent an effective alternative to methadone in stress-sensitive, heroin-dependent patients.

Abstract
The role of withdrawal-related phenomena in the development and maintenance of alcohol addiction remains under debate. A 'self-medication' framework postulates that emotional changes are induced by a history of alcohol use, persist into abstinence, and are a major factor in maintaining alcoholism. This view initially focused on negative emotional states during early withdrawal: these are pronounced, occur in the vast majority of alcohol-dependent patients, and are characterized by depressed mood and elevated anxiety. This concept lost popularity with the realization that in most patients, these symptoms abate over 3-6 weeks of abstinence, while relapse risk persists long beyond this period. More recently, animal data have established that a prolonged history of alcohol dependence induces more subtle neuroadaptations. These confer altered emotional processing that persists long into protracted abstinence. The resulting behavioral phenotype is characterized by excessive voluntary alcohol intake and increased behavioral sensitivity to stress. Emerging human data support the clinical relevance of negative emotionality for protracted abstinence and relapse. These developments prompt a series of research questions: (1) are processes observed during acute withdrawal, while transient in nature, mechanistically related to those that remain during protracted abstinence?; (2) is susceptibility to negative emotionality in acute withdrawal in part due to heritable factors, similar to what animal models have indicated for susceptibility to physical aspects of withdrawal?; and (3) to what extent is susceptibility to negative affect that persists into protracted abstinence heritable?

Abstract
BACKGROUND Although decision-making processes have become a principal target of study among addiction researchers, few studies have specifically examined decision-making among individuals with alcohol dependence (AD) and findings to date are mixed. The present study examined the relationship between AD and decision-making, and tested whether different facets of antisocial and psychopathic traits explain this association. METHODS Participants were men with AD (n = 22), AD and comorbid antisocial personality disorder (AD + ASPD; n = 17), or a history of recreational alcohol use, but no current or lifetime symptoms of a substance use disorder, conduct disorder, or ASPD (n = 21). Decision-making was tested using the Iowa Gambling Task (IGT). RESULTS Across groups, participants reported similar levels of awareness of the contingencies of the task, but the AD groups with and without ASPD had poorer IGT performance compared with controls (p < 0.05). A block-by-block analysis revealed that while AD had slow but steady improvement across the task, AD + ASPD exhibited initial improvement followed by a significant decrease in advantageous decision-making during the last 20 trials (p < 0.05). This was further confirmed via evidence that impulsive/antisocial personality traits but not psychopathic traits mediated poor IGT performance beyond ASPD diagnosis. CONCLUSIONS Alcohol-dependent males favored risky choices regardless of whether they met criteria for ASPD. However, decision-making deficits were more pronounced among those with ASPD, and personality traits characterized by impulsive and antisocial tendencies mediated the relationship between AD and decision-making.

Abstract
Recent conceptualizations of alcohol expectancies relate cognitive schemas to their neurobiological underpinnings; cue reactivity paradigms lend themselves well to testing this broadened conceptual framework. In the present study, we examined the relationship between self-reported alcohol expectancies and responses to alcohol-related and affective picture cues among fifty-five young adults. In addition to traditional subjective and psychophysiological indices of cue reactivity, the startle eyeblink reflex was obtained during picture cue presentations to address both attention-arousal (early probes) and affective-motivational (late probes) aspects of cue processing. Analyses indicated that participants reporting greater positive, arousing, and social alcohol expectancies rated alcohol cues as more pleasant, arousing, and craving-inducing. In addition, participants displayed inhibited startle reactivity to late alcohol cue probes, indicative of an appetitive reaction. Finally, startle responding to early probes indicated that participants with greater alcohol expectancies displayed blunted attention to negative affect cues. Findings are discussed in terms of the utility of the startle reflex and cue reactivity paradigms for clarifying the relationship between alcohol expectancies and motivated attention to salient cues.

Abstract
Almost all we know about neurobiological brain injury in alcohol use disorders has been derived from convenience samples of treated alcoholics. Recent research has demonstrated more comorbid conditions, poorer psychosocial functioning, and higher dependence levels in treated alcoholics than in their treatment-naive counterparts. Thus, it is not clear whether neuroimaging results from convenience samples of treated alcoholics can be generalized to the entire population with alcohol use disorders. We compared 35 treated alcoholics at 1 week of abstinence (ALC) and 32 treatment-naive heavy drinkers (HD) on regional brain volumes and metabolite concentrations obtained by in vivo magnetic resonance at 1.5 Tesla to evaluate for potential group differences. Then, we evaluated whether comorbid cigarette smoking and common demographic and clinical variables mediated any existing neurobiological group differences. ALC demonstrated smaller lobar gray matter volumes and thalami than HD, exacerbated by chronic smoking. Furthermore, concentrations of N-acetyl-aspartate (an accepted marker of neuronal viability), choline-containing metabolites (involved in membrane turnover), and myo-inositol (a putative marker of glial cells and osmolyte) were lower in multiple brain regions of ALC compared to HD. The lower N-acetyl-aspartate concentrations in white matter of ALC versus HD were explained by average number of drinks per month over the year preceding study. However, the other group differences were not explained by common drinking, demographic, and clinical variables (used as covariates at the same time) or by excluding participants with comorbid mood disorders. Taken together, this suggests that the degree of brain atrophy, as well as neuronal and membrane injury in clinical samples of alcoholics cannot be generalized to the much larger population with alcohol use disorders that does not seek treatment.

Abstract
Impaired emotional responsiveness has been revealed as a hallmark of psychopathy. In spite of an increasing database on emotion processing, studies on cognitive function and in particular on the impact of emotion on cognition in psychopathy are rare. We used pictures from the International Affective Picture Set (IAPS) and a Simon Paradigm to address emotion-cognition interaction while functional and structural imaging data were obtained in 12 healthy controls and 10 psychopaths. We found an impaired emotion-cognition interaction in psychopaths that correlated with a changed prefrontal and temporal brain activation. With regard to the temporal cortex, it is shown that structure and function of the right superior temporal gyrus is disturbed in psychopathy, supporting a neurobiological approach to psychopathy, in which structure and function of the right STG may be important.

Abstract
BACKGROUND Alcoholism is characterized by deficits in emotional functioning as well as by deficits in cognitive functioning. However, most brain imaging research on alcoholism has focused on cognition rather than emotion. METHOD We used an event-related functional magnetic imaging approach to examine alcoholics' brain blood oxygenation level dependent (BOLD) response to evaluation of emotional stimuli and to compare their response to that of nonalcoholic controls. The task used was a simplified variant of a facial emotion-decoding task in which subjects determined the intensity level of a target emotion displayed as a facial expression. Facial expressions of happy, sad, anger, disgust, and fear were used as stimuli. RESULTS Alcoholics and controls did not differ in accurately identifying the intensity level on the simple emotional decoding task but there were significant differences in their BOLD response during evaluation of facial emotion. In general, alcoholics showed less brain activation than nonalcoholic controls. The greatest differences in activation were during decoding of facial expressions of fear and disgust during which alcoholics had significantly less activation than controls in the affective division of the anterior cingulate cortex (ACC). Alcoholics also had significantly less activation than controls in the affective division of the ACC, while viewing sad faces. Only to facial expressions of anger did the alcoholics show significant activation in the affective ACC and in this case, their BOLD response did not significantly differ from that of the controls. CONCLUSION Alcoholics show a deficit in the function of the affective division of the ACC during evaluation of negative facial emotions that can serve as cues for flight or avoidance. This deficit may underlie some of the behavioral dysfunction in alcoholism.

Abstract
Emotion-modulated startle reflex is an important indicator of traitlike differences in affective processing implicated in the biological basis of personality and psychopathology. This study examined heritability of startle modulation by affective pictures in 66 pairs of monozygotic and 57 pairs of dizygotic female twins. Consistent with previous studies, startle magnitude was significantly influenced by emotional valence of the picture (positive < neutral < negative). Absolute response magnitude showed high heritability in all three valence conditions (59-61%); however, there were no significant genetic influences on the amount of startle modulation. Thus, our data do not support the hypothesis that emotion-modulated startle can serve as an indicator of genetically transmitted individual differences in affective processing.

Abstract
Abstinent alcoholics show a blunted stress cortisol response that may be a consequence of drinking or a preexisting risk marker. We tested cortisol responses to psychological stress in 186 18-30 year-old, healthy social drinkers having no personal history of alcohol or drug dependence, 91 of whom had one or two alcoholic parents (FH+) and 95 having no family alcoholism for two generations (FH-). We predicted that, similar to alcoholic patients, the FH+ would have reduced stress cortisol responses that would be partially determined by their temperament characteristics, specifically antisocial tendencies as measured by the California Psychological Inventory. On a stress day, subjects performed continuous simulated public speaking and mental arithmetic tasks for 45 min, and on a control day they sat and rested for the same time period. The FH+ who were low in sociability had smaller cortisol responses than FH-, high-sociability persons (t=2.27, p=.02). These two groups were not different in diurnal cortisol secretion patterns or affective responses to the stressors. Persons with a familial risk for alcoholism who have more antisocial tendencies may have altered central nervous system responses to emotionally relevant social challenges. Disrupted cortisol stress responses may serve as a risk marker for the development of substance use disorders.
