The inhibitory spillover effect: Controlling the bladder makes better liars
Elise Fenn et al.
Consciousness and Cognition, December 2015, Pages 112–122
Abstract:
The Inhibitory-Spillover-Effect (ISE) on a deception task was investigated. The ISE occurs when performance in one self-control task facilitates performance in another (simultaneously conducted) self-control task. Deceiving requires increased access to inhibitory control. We hypothesized that inducing liars to control urination urgency (physical inhibition) would facilitate control during deceptive interviews (cognitive inhibition). Participants drank small (low-control) or large (high-control) amounts of water. Next, they lied or told the truth to an interviewer. Third-party observers assessed the presence of behavioral cues and made true/lie judgments. In the high-control, but not the low-control condition, liars displayed significantly fewer behavioral cues to deception, more behavioral cues signaling truth, and provided longer and more complex accounts than truth-tellers. Accuracy detecting liars in the high-control condition was significantly impaired; observers revealed bias toward perceiving liars as truth-tellers. The ISE can operate in complex behaviors. Acts of deception can be facilitated by covert manipulations of self-control.

Humility Facilitates Higher Self-Control
Eddie Tong et al.
Journal of Experimental Social Psychology, January 2016, Pages 30–39
Abstract:
Prior evidence and existing theories imply that humility engenders intra- and inter-personal attributes that facilitate self-regulatory abilities. Four experiments were conducted to test the hypothesis that humility predicts enhanced self-control. Participants who recalled humility experiences were found to be better able at sustaining their physical stamina in a handgrip task (Studies 1 and 4), resisting indulgence in chocolates (Study 2), and persevering in a frustrating tracing task (Study 3) than those who recalled neutral experiences. Studies 3 and 4 demonstrated that the effect of humility was distinct from that of self-esteem, which did not affect self-control. Study 2 ruled out two alternative hypotheses concerning achievement and compliance motives. We discuss how the findings might relate to outcomes associated with humility as evidenced in past studies.

Abstract:
Can growing up in a stressful childhood environment enhance certain cognitive functions? Drawing participants from higher-income and lower-income backgrounds, we tested how adults who grew up in harsh or unpredictable environments fared on 2 types of executive function tasks: inhibition and shifting. People who experienced unpredictable childhoods performed worse at inhibition (overriding dominant responses), but performed better at shifting (efficiently switching between different tasks). This finding is consistent with the notion that shifting, but not inhibition, is especially useful in unpredictable environments. Importantly, differences in executive function between people who experienced unpredictable versus predictable childhoods emerged only when they were tested in uncertain contexts. This catalyst suggests that some individual differences related to early life experience are manifested under conditions of uncertainty in adulthood. Viewed as a whole, these findings indicate that adverse childhood environments do not universally impair mental functioning, but can actually enhance specific types of cognitive performance in the face of uncertainty.

Trading Later Rewards for Current Pleasure: Pornography Consumption and Delay Discounting
Sesen Negash et al.
Journal of Sex Research, forthcoming
Abstract:
Internet pornography is a multi-billion-dollar industry that has grown increasingly accessible. Delay discounting involves devaluing larger, later rewards in favor of smaller, more immediate rewards. The constant novelty and primacy of sexual stimuli as particularly strong natural rewards make Internet pornography a unique activator of the brain's reward system, thereby having implications for decision-making processes. Based on theoretical studies of evolutionary psychology and neuroeconomics, two studies tested the hypothesis that consuming Internet pornography would relate to higher rates of delay discounting. Study 1 used a longitudinal design. Participants completed a pornography use questionnaire and a delay discounting task at Time 1 and then again four weeks later. Participants reporting higher initial pornography use demonstrated a higher delay discounting rate at Time 2, controlling for initial delay discounting. Study 2 tested for causality with an experimental design. Participants were randomly assigned to abstain from either their favorite food or pornography for three weeks. Participants who abstained from pornography use demonstrated lower delay discounting than participants who abstained from their favorite food. The finding suggests that Internet pornography is a sexual reward that contributes to delay discounting differently than other natural rewards. Theoretical and clinical implications of these studies are highlighted.

Reducing the Disruptive Effects of Interruptions With Noninvasive Brain Stimulation
Eric Blumberg et al.
Human Factors: The Journal of the Human Factors and Ergonomics Society, September 2015, Pages 1051-1062
Objective: The authors determine whether transcranial direct current stimulation (tDCS) can reduce resumption time when an ongoing task is interrupted.
Method: Participants were randomly assigned to one of four groups that received anodal (active) stimulation of 2 mA tDCS to one of two target brain regions, left and right dorsolateral prefrontal cortex (DLPFC), or to one of two control areas, active stimulation of the left primary motor cortex or sham stimulation of the right DLPFC, while completing a financial management task that was intermittently interrupted with math problem solving.
Results: Anodal stimulation to the right and left DLPFC significantly reduced resumption lags compared to the control conditions (sham and left motor cortex stimulation). Additionally, there was no speed-accuracy tradeoff (i.e., the improvement in resumption time was not accompanied by an increased error rate).
Conclusion: Noninvasive brain stimulation can significantly decrease resumption lag (improve performance) after a task is interrupted.

The Effect of Preference Expression Modality on Self-Control
Anne-Kathrin Klesse, Jonathan Levav & Caroline Goukens
Journal of Consumer Research, forthcoming
Abstract:
The marketplace affords consumers various modalities to express their preferences (e.g., by pressing a button on a vending machine or making an oral request at a restaurant). In this paper, we compare speaking to manual preference expression modalities (button pressing, writing, and taking) and study their effect on self-control dilemmas. Based on studies of the Stroop task and on neuroscientific evidence, we predict that speaking is less likely than motor movement to evoke self-control. Our prediction relies on the observation that different expression modalities activate different regions of the anterior cingulate cortex (ACC), and, hence, may influence the extent to which emotions rather than cognitions determine an individual’s decision. In six studies conducted both in the lab and the field, we show that speaking prompts more indulgent choice than manual modalities (studies 1a,b-4), but not when individuals speak in a foreign language (study 5).

It Was(n’t) Me: Exercising Restraint When Choices Appear Self-Diagnostic
Maferima Touré-Tillery & Ayelet Fishbach
Journal of Personality and Social Psychology, forthcoming
Abstract:
This research tests the hypothesis that individuals exercise restraint for actions that reflect on their self-concept (i.e., self-diagnostic actions). Experiments 1 and 2 show an action framed as occurring at the beginning or end (vs. middle) of a constructed sequence is seen as more self-diagnostic. Accordingly, Experiment 3 finds more restraint in snack choices at the framed beginning or end (vs. middle). Furthermore, the degree of importance of a goal — which reflects its centrality to the self-concept — determines responses to self-diagnosticity cues such as framed positions. Specifically, participants committed to financial goals (Experiment 4) and health goals (Experiment 5) were more likely to make decisions consistent with these goals at the beginning or end, but indulged and splurged in the middle. Experiment 6 shows similar patterns for judgments of magazine subscriptions, but only when individuals are faced with a decision that poses a self-control conflict for them. These results highlight the role of the self in self-control by demonstrating that people exercise restraint when decision contexts seem more telling of the self.

Abstract:
Adolescents take more risks with peers than when alone. It is not clear how peer presence affects adolescents' risky decision making, however. We used the Iowa Gambling Task (IGT) — a game used to assess decision making involving risk and reward — to examine how peers affect late adolescents' exploration of relevant environmental cues, ability to learn from the outcomes (positive and negative) of that exploration, and ability to integrate feedback to adjust behavior toward optimal long-term outcomes. One hundred and one 18- to 22-year old males (M = 19.8 years) were randomly assigned to play the IGT either alone or observed by peers. Late adolescents tested with observers engaged in more exploratory behavior, learned faster from both positive and negative outcomes, and evinced better task performance than those tested alone.
