No significant differences between control and MBO participants were found when sober, or after ingesting alcohol, on free and serial recall tasks. In addition, we ran resampling analyses for each individual’s performance between before-alcohol Top 5 Advantages of Staying in a Sober Living House and after-MBO conditions in all the tasks to quantify the significance of blackout effects. For the free recall task, accuracy in 10 out of 23 participants (43.5%) was significantly impaired after experiencing an MBO (see Fig 2C).
Study setting and participants
All experiments were presented using experimental software E-Prime 1.2 (Psychology Software Tools, Pittsburgh, PA). In both the Free and Serial tasks, participants were presented with 3 blocks of 15 study words on a computer screen and asked to remember them. Stimuli were word lists taken from Roediger and McDermott [38], totalling 270 unique stimuli split into 18 blocks (9 blocks free recall task, 9 blocks serial recall task). Blocks for each individual task were presented pseudo-randomly, counterbalanced across participants. In study blocks, individual words were presented for 1000ms, followed by a blank inter-trial interval of 2000ms.
- We did this to investigate if recall for items embedded in a context is affected more by an alcohol-induced MBO compared to our shallow encoding manipulation.
- This study has a number of notable strengths including the intensive experience sampling protocol, the relatively large N for this type of protocol, and the burst design, which results in the longest experience sampling study of veterans to date.
- Although our subsample size of 70 examining mediation in men was small for many analyses, this was well over the suggested minimum of 25 for bootstrapping mediation (Preacher & Hayes, 2004).
- The abstinence duration was determined by inquiring the most recent alcohol consumption episode, and participants responded to whether or not they had ever engaged in driving under the influence of alcohol.
- They were given as much time as they wanted to complete the recall component for each block.
Types of Blackouts
An MBO occurs when a rapid rise in blood alcohol levels disrupts processing within the hippocampus [5]. The term fragmentary blackout describes the more commonly experienced type of MBO, where episodic https://megapolisnews.com/top-5-advantages-of-staying-in-a-sober-living-house/ memory is punctuated by brief periods of memory loss. Some recovery of episodes has been observed in people after experiencing a fragmentary blackout, yet this often follows from cues by peers [7].

To make this transition smoother, compile a Distraction List – a collection of activities to engage in instead of reaching for a drink. Knowing you have a list to refer to during these moments can be incredibly helpful. Your journey toward sobriety is a courageous and empowering one, and you are not alone. Seeking professional support is a significant stride towards a healthier, brighter future.
