OBJECTIVE En bloc and fragmentary blackouts are distinguishable forms of alcohol-induced amnesia. The former are instances of full and permanent memory loss for intoxicated events, whereas the latter are episodes for which retrieval of experiences is facilitated by provision of cues. Beyond this nosological difference, little is known about descriptive dimensions of the two blackout types. The current study assessed their characteristics as reported by a group of heavy drinking young adults… 
Distinctions in Alcohol‐Induced Memory Impairment: A Mixed Methods Study of En Bloc Versus Fragmentary Blackouts
Young adults are more permissive of fragmentary than en bloc blackout, and en bloc blackouts may be a target for future interventions.

The authors concluded that the results of their analysis indicated that blackouts during serious misbehavior are often reported outside the court, but the denial or claim of alcoholic blackout may serve a strategic function for the person who raises the claim.
Alcohol-Induced Blackouts as Predictors of Other Drinking Related Harms Among Emerging Young Adults.
Having a blackout was the strongest independent predictor of most other alcohol problems examined, including in the past 6 months because of drinking, missing class or work, getting behind in work or school, doing something respondents later regretted, arguing with friends, experiencing an overdose, and total number of alcohol problems reported.

Blackouts are much more common among social drinkers—including college drinkers—than was previously assumed, and have been found to encompass events ranging from conversations to intercourse.
Acute alcohol effects on contextual memory BOLD response: differences based on fragmentary blackout history.
Alcohol had differential effects on neural activity for FB+ and FB- individuals during recollection of contextual information, perhaps suggesting a neurobiological mechanism associated with alcohol-induced FB.

The Association of Alcohol‐Induced Blackouts and Grayouts to Blood Alcohol Concentrations
A strong linear relationship between BAC and predicted probability of memory loss, particularly for blackouts was obvious, and it is concluded that subjects with BAC of 310 g/dL or greater have a 0.50 or greater probability of having an alcoholic blackout.
A Longitudinal Examination of Alcohol-Related Blackouts as a Predictor of Changes in Learning, Memory, and Executive Function in Adolescents
Introduction In adolescents, the relationship between alcohol-related blackouts (ARBs) and distinct cognitive changes lasting beyond intoxication is unclear. We examined ARBs as a predictor of
Alcohol-Induced Blackouts: A Review of Recent Clinical Research with Practical Implications and Recommendations for Future Studies.
It is suggested that individual differences, not just alcohol consumption, increase the likelihood of experiencing an alcohol-induced blackout, and the consequences of alcohol- induced blackouts extend beyond the consequences related to the drinking episode to include psychiatric symptoms and neurobiological abnormalities.


Fragmentary blackouts: their etiology and effect on alcohol expectancies.
It is suggested that fragmentary blackouts result from poor retrieval and that individual differences in retrieval emerge after alcohol is consumed, as well as of prospective expectations for positive alcohol effects.
Drinking-induced blackouts among young adults: results from a national longitudinal study.
It is concluded that the blackout remission rate observed among a substantial proportion (68%) of young adults may not fit the progressive, irreversible model of alcoholism.
The prognostic importance of blackouts in young men.
The data suggest that blackouts should be viewed as an important warning sign of problem drinking, but not as the "hallmark" of alcoholism.

Alcohol, reaction time and memory: a meta-analysis.
Alcohol appears to have a general linear effect on information processing, rather than specific effects on a subset of stages, as indicated by the results of reaction time and recognition memory studies.
Acute alcohol intoxication and cognitive functioning.
Analysis of the results of the cognitive test battery demonstrated that a high dose of alcohol detrimentally affects a number of functions associated with the prefrontal and temporal lobes, including planning, verbal fluency, memory and complex motor control.
Getting drunk and growing up: trajectories of frequent binge drinking during the transition to young adulthood.
Results from logistic regression analyses predicting diverging and converging trajectories provided some support for the general hypothesis that trajectories of Chronic and Increased frequent binge drinking over time are associated with difficulties in negotiating the transition to young adulthood.

Alcohol consumption by college undergraduates: current use and 10-year trends.
In a carefully executed study with a high response rate, a random sample of 10% of the undergraduate student body at a rural New England university was surveyed as to the subjects' use of alcohol in 1987, finding most of the drinking is done by one-fifth of both groups.
