Predicting habit: The case of physical exercise

ObjectivesHabit has been an undervalued concept in the behavioral sciences during the past few decades. One reason may be that habit has been equated with behavioral frequency. This leaves out an important characteristic of habits, i.e., the fact that repeated behavior may acquire a degree of automaticity. The present study aimed to demonstrate that exercising habit can be reliably measured, can empirically be distinguished from past frequency of exercising, and can thus be adopted as a meaningful criterion.Design and methodsA longitudinal study was conducted with two measurements one month apart among 111 students. Intentions to exercise, perceived behavioral control of exercising, past exercising frequency, and exercising habit were assessed at both measurements through an internet-based questionnaire. Exercising habit was assessed by the Self-Report Habit Index [Verplanken & Orbell (2003). Reflections on past behaviour: A self-report index of habit strength. Journal of Applied Social Psychology, 33, 1313–1330]), which breaks down the habit concept in the subjective experience of repetition and automaticity.ResultsThe results showed that exercising habit can be reliably measured, is stable over time, and can be distinguished from mere exercising frequency.ConclusionsIn addition to frequency of behavior, measuring habit provides information about the way behavior is executed. An important element of exercising behavior is the decision to go exercise. It is argued that the habit concept is therefore particularly relevant for the initiation of and adherence to exercising. Implications of distinguishing behavioral frequency and habit for interventions are discussed.     

Procrastination out of Habit? The Role of Impulsive Versus Reflective Media Selection in Procrastinatory Media Use

ABSTRACT

The pervasive access to media options seriously challenges users’ self-regulatory abilities. One example of deficient self-regulation in the context of media use is procrastination—impulsively ‘giving in’ to available media options despite goal conflicts with more important tasks. This study investigaes procrastinatory media use across 3 types of media (TV, computer, smartphone) from a dual-systems perspective, taking both person-level and situation-level predictors into account. Results from a 14-day long diary study (N = 347) suggest that procrastinatory media use is driven by automatic media selection, which is facilitated by strong media habits (person level) and low motivation for behavioral control (situation level). The results underline the value of a dual-systems perspective on media choices in our media-saturated environment.     

Exploring psychological factors of mobile phone use while riding among motorcyclists in Vietnam

Mobile phone use while riding is one of the five most common risky behaviors of motorcycle riders in Vietnam. This study investigated motorcyclist’s mobile phone use while riding intention and behavior based on the extended Theory of Planned Behavior (TPB) framework. Based on this framework, attitude, subjective norm, perceived behavioral control, habits, and health motivation underlying the rider’s mobile phone use while riding intentions and behavior were included in a questionnaire and captured by direct and indirect measurements. Small-displacement motorcycle riders (N = 291) completed the extended TPB based questionnaire. An exploratory factor analysis technique identified the selected factors (e.g., attitude, habit, etc.). Moreover, Structural Equation Modeling results showed moderate to good fits to the observed data. Therefore, the results supported the utilization of extended TPB framework in identifying factors of mobile phone use while riding intention and behavior. Specifically, negative attitude, perceived behavioral control, and mobile phone use while riding habit related to the intention to use a mobile phone while riding of small-displacement motorcyclists. Meanwhile, habit and behavioral intention related to the behavior to use a mobile phone while riding of small-displacement motorcycle riders. Especially, the correlation between behavioral intention and self-reported behavior was very strong. This finding embraced previous research indicating that intention was a major motivational component of behavior. Based on the results, safety intervention implications for small-displacement motorcycle riders were discussed.     

Experimental test of a planning intervention for forming a ‘higher order’ health-habit

Abstract

Objective: Habit-formation interventions may help individuals initiate and maintain behaviour change. This paper proposes and empirically tests the idea that it is possible for individuals to form ‘higher-order habits’, or behaviours that can be executed in more than one way, and still be habitual.

Design: Participants (N?=?82) were healthy adults randomly assigned to an action-and-coping-planning intervention for forming a ‘higher-order habit’ of filling half of their dinner plates with fruits and vegetables or a control condition. Key measures were collected at baseline and 1, 2 and 3 weeks post-baseline. Participants submitted 3 pictures per week of their dinner plates via snapchat/email.

Main Outcome Measures: Intrinsic motivation, habit strength and behavioural frequency for filling half their dinner plates with fruits and vegetables.

Results: Intervention participants reported significantly greater habit strength at each follow-up time point. Controls did show some degree of habit formation, despite not fully forming a habit. Behavioural automaticity increased despite consuming a variety of fruits/vegetables; results did not depend on participants’ intrinsic motivation to consume fruits/vegetables.

Conclusion: It may be possible for individuals to form ‘higher-order’ habits, which may be particularly important in health contexts, in which many target behaviours are complex and can be seen as higher-order.     

Habit as mediator of the relationship between prior and later physical activity: A longitudinal study in older adults

ObjectivesHabit has been proposed as an explanation of why prior behavior is a good predictor of later behavior. This study examined whether habit mediates the relationship between prior and later physical activity (PA), within the framework of the attitude-social influences-efficacy (ASE) model and the theory of planned behavior (TPB).DesignA longitudinal design was used.MethodsA total of 1976 older adults completed questionnaires on ASE/TPB constructs and PA at baseline, intention at three months, habit at six months, and PA at twelve months.ResultsPath analyses showed that habit significantly mediates the relationship between prior and later PA, after ASE/TPB variables were taken into account.ConclusionsHabit is a partial solution to the question why prior PA is a good predictor of later PA. It is recommended to incorporate habit into the ASE/TPB model.     

Positive correlation between measures of habitual responding and motivated responding in mice

Habit and motivation are thought to be separate processes, with motivated behavior often considered to be goal directed, whereas habits are defined by the absence of goal-directed control over behavior. However, there has been increasing interrogation of the binary nature of habitual versus goal-directed behavior. Furthermore, although drug and alcohol exposure can promote the formation of habits, drug seeking itself can also be highly flexible, pointing toward the need for complex consideration of the parallel processes that drive behavior. The goal of the current study was to determine whether there was a relation between motivation—as measured by progressive ratio—and habit—as measured by contingency degradation—and whether this relation was affected by ethanol exposure history and sex. The results showed that these measures were positively correlated such that greater contingency insensitivity was associated with achieving higher break points on the progressive-ratio task. However, this relation depended on reinforcement schedule history, ethanol exposure history, and sex. These point to potential relations between measures of habit and motivation and stress the importance of carefully parsing behavioral findings and assays. These findings are also expected to inform future substance use research, as drug history may affect these relations.     

Achieving Higher Seat Belt Usage: The Role of Habit in Bridging the Attitude-Behavior Gap1

The Triandis (1977, 1980) model of habit is applied in an investigation of attitude-behavior discrepancy for seat belt use behavior. Habit is conceptualized as automated response, and the measure employed here is shown to be discriminated from measures of intentions and behavior. A case is also made for a distinction between pro-intentional and counter-intentional habits. Data from a random sample of 197 adult respondents show that the two habits (a) are distinct; (b) operate differently, that is, use habit has a main effect whereas nonuse habit interacts with attitude/intentions; and (c) explain belt use behavior nonredundantly with intention and attitude (e.g., their addition to attitude raises R² from 38.8% to 62.9%). Theoretical implications for understanding habit processes and programmatic directions for increasing the belt usage are discussed.     

习惯研究的现状与展望

习惯是一种由某特定线索引发并指向某特定目标(包括外显目标与内隐目标)的自动化反应。它具有过去有行为的重复、环境线索的稳定与自动化的反应等特征。关于习惯的测量方式主要采取自我报告法（如自我报告过去行为频率、自我报告习惯频率、自我报告习惯索引等）和反应频率测量法。对习惯的形成的理论解释主要有环境促进、态度促进、目标促进等几种观点。未来研究应继续深入探讨习惯的本质、整合形成机制的相关理论及开发更可靠方便的测量工具。     

How do habits guide behavior? Perceived and actual triggers of habits in daily life

What are the psychological mechanisms that trigger habits in daily life? Two studies reveal that strong habits are influenced by context cues associated with past performance (e.g., locations) but are relatively unaffected by current goals. Specifically, performance contexts—but not goals—automatically triggered strongly habitual behaviors in memory (Experiment 1) and triggered overt habit performance (Experiment 2). Nonetheless, habits sometimes appear to be linked to goals because people self-perceive their habits to be guided by goals. Furthermore, habits of moderate strength are automatically influenced by goals, yielding a curvilinear, U-shaped relation between habit strength and actual goal influence. Thus, research that taps self-perceptions or moderately strong habits may find habits to be linked to goals.     

Are action planning and physical activity mediators of the intention-habit relationship?

ObjectivesPhysical activity is associated with many health benefits that are important for older adults. These health benefits can only be obtained and preserved when physical activity is maintained over a long period of time. Habit formation has been proposed as a way to ensure long-term maintenance of physical activity. Intention, action planning, and physical activity are suggested to be determinants of physical activity habits. However, how they determine physical activity habits in older adults is largely unknown. This study examined whether the relationship between intention and habit is mediated by action planning and/or physical activity.DesignA four-wave prospective design was used.MethodsTwo independent studies were conducted in 469 (Study 1; M_age = 63.07, SD_age = 7.61) and 322 (Study 2; M_age = 64.31, SD_age = 9.39) older adults. Study 2 was conducted with the aim of replicating findings of Study 1. In both studies the older adults completed questionnaires on intention, physical activity, and habit at baseline, action planning at three months, physical activity at six months, and habit at twelve months.ResultsStructural equation modeling analyses showed significant intention-physical activity-habit paths, nonsignificant intention-action planning-habit paths, and nonsignificant intention-action planning-physical activity-habit paths in both studies.ConclusionsThe relationship between physical activity habit and intention was mediated by physical activity. Intention was neither associated with habit via action planning as a single mediator, nor via action planning and physical activity as sequential mediators. Possible conditions under which intention-action planning-habit paths and intention-action planning-physical activity-habit paths exist are discussed.     

Habit strength moderates the strength of within-person relations between weekly self-reported and objectively-assessed physical activity

ObjectivesPhysical activity (PA) habit strength influences how people control their PA and may also influence how people encode, store, or recall their PA. This study evaluated whether individual differences in PA habit strength moderated the magnitude of within-person associations between weekly self-reported PA and step counts.DesignLongitudinal.MethodAfter an initial assessment of PA habit strength, university students wore pedometers for four weeks and completed four self-reports of weekly mild, moderate, and strenuous PA.ResultsOn average, people's weekly step counts and self-reported PA across time were weakly-to-moderately associated, but there was substantial variability in the magnitude of these associations across people. People with strong PA habits had weaker within-person associations between deviations from their average self-reported PA and step counts than those with weak PA habits.ConclusionsThese results may indicate that PA habit strength influences the sensitivity of self-report PA measures to change in objectively-measured PA.     

Hegel's real habits

Hegel frequently identifies ethical life with a “second nature.” This strategy has puzzled those who assume that second nature represents a deficient appearance of ethical life, one that needs to be overcome, supplemented, or constantly challenged. I argue that Hegel identifies ethical life with a second nature because he thinks that a social order only becomes a candidate for ethical life, if it provides a context conducive to the development of what I call “real habits.” First, I show that a criterion for a real habit can be found in Hegel's Anthropology, namely, that of liberation. Next, I explain how the state, as Hegel analyzes it in the Philosophy of Right, provides such an environment by enabling trust toward and within it. I then consider two literary examples of contexts that fail to be similarly supportive—Coates' Between the World and Me and Atwood's Handmaid's Tale—concluding with reasons for thinking that real habits are an integral part of ethical life.     

From intentions via planning and behavior to physical exercise habits

ObjectivesIndividuals who enact a health behavior effortlessly with minimal conscious deliberation can be assumed to have formed a healthy habit. This can be reflected by increases in self-reported habit strength of a behavior. We examined whether physical exercise intentions facilitate changes in exercise habit strength by increasing the use of action planning and exercise.DesignTwo field studies investigated the effect of behavioral intentions on changes in habit strength through a sequential path from action planning to exercise.MethodExercise intentions, action planning, habit strength, and exercise were assessed at two measurement points in time in 231 university students (Study 1), and at four points in time in 134 rehabilitation patients (Study 2).ResultsIn multiple-step mediation models in both samples, there were indirect effects of intentions on habit strength through action planning and behavior.ConclusionAction planning and behavior operated as sequential mediators to bridge the gap between intentions and habit strength. Exercise habit strength may increase as a result of conscious action planning and frequent behavior enactment. Including these constructs jointly into behavior change models may improve the understanding of the mechanisms involved in behavior maintenance.     

Does habit weaken the relationship between intention and behaviour? Revisiting the habit‐intention interaction hypothesis

Habitual behaviours are elicited when a familiar context activates cue‐behaviour associations that have been learned through previous performance. A core hypothesis within habit theory is that, by virtue of its automaticity, habit weakens the impact of intention on action, such that in facilitating conditions, action will be guided more by habit than momentary intentions. This has led to recommendations that habit formation be harnessed as a mechanism for sustaining desirable behaviour over time, when people would otherwise relapse due to loss of motivation. This article reviews theory and evidence around the hypothesized interaction between habit and intention as determinants of behaviour. We first qualify the hypothesis by clarifying that it pertains only to determinants of the instigation of action, rather than execution. Next, drawing on a systematic review of 52 behaviour‐prediction studies, we highlight mixed empirical support for the interaction. We argue that ostensibly inconsistent findings can be reconciled by recognizing the distinction between the direction and strength of intention, and identifying the “facilitating conditions” that may determine the relative influence of habit and intention on behaviour. Evidence demonstrates that when self‐control is diminished, people act habitually regardless of intention direction or strength. When people possess self‐control, habits can help people to act on favourable but weakened intentions, but intentions that oppose habitual tendencies can override habitual influence. This has important implications for behaviour change: even if habit has formed, a minimal level of favourable conscious motivation may be required to sustain behaviours over time. Social psychology might fruitfully move beyond asking whether habit moderates the intention‐behaviour relationship, and instead probe how and in which conditions habits and intentions interact.     

A survey of smoking status and cancer risk perceptions among participants attending a hospital-based head and neck screening program

Abstract

Screening for head and neck cancer is underutilized. Given that lack of knowledge of the risk factors may partially account for screening underutilization. we surveyed subjective risk and knowledge of risk factors for head and neck cancer among 124 individuals who attended a free. hospital-based head and neck cancer screening. Few participants were current smokers. Most attendees perceived their risk as similar to others of their age and sex. Personal health habits comprised almost all of the risk-decreasing factors, yet less than half of the risk-increasing factors. generated. Personal habits were less frequently endorsed than factors such as pollution and heredity. Those who mentioned a risk behavior, or a family cancer history, reported higher subjective risk. Those who mentioned a personal health habit reported lower subjective risk. Results highlight needed efforts to increase screening among high-risk individuals through targeted education messages.     

The pull of the past: when do habits persist despite conflict with motives?

To identify the factors that disrupt and maintain habit performance, two field experiments tested the conditions under which people eat out of habit, leading them to resist motivational influences. Habitual popcorn eaters at a cinema were minimally influenced by their hunger or how much they liked the food, and they ate equal amounts of stale and fresh popcorn. Yet, mechanisms of automaticity influenced habit performance: Participants ate out of habit, regardless of freshness, only when currently in the context associated with past performance (i.e., a cinema; Study 1) and only when eating in a way that allowed them to automatically execute the response cued by that context (i.e., eating with their dominant hand; Study 2). Across all conditions, participants with weaker cinema-popcorn-eating habits ate because of motivations such as liking for the popcorn. The findings reveal how habits resist conflicting motives and provide insight into promising mechanisms of habit change.     

An Examination of Functional Difficulties From Internet Use: Media Habit and Displacement Theory Explanations

Seminal studies concerning the Internet brought legitimacy to public concerns about its dissocializing effects. Although the negative social and professional outcomes of the Internet are still attributed to the time users spend online, scholars have more recently turned their attention to media habits in explaining these effects. This investigation tests the displacement and media habit perspectives on the consequences of Internet use. Study 1 uses cross‐sectional data to test the displacement and Internet habit positions. The data support media habit theory explanations but find little support for displacement theory. Study 2 replicates the results of Study 1 with longitudinal data from incoming college freshmen. Study 3 holds time constant and examines the causal direction between functional difficulties and habit strength     

N-of-1 study of weight loss maintenance assessing predictors of physical activity,adherence to weight loss plan and weight change

Objective: Behaviour change interventions are effective in supporting individuals to achieve clinically significant weight loss, but weight loss maintenance (WLM) is less often attained. This study examined predictive variables associated with WLM.

Design: N-of-1 study with daily ecological momentary assessment combined with objective measurement of weight and physical activity, collected with wireless devices (Fitbit?) for six months. Eight previously obese adults who had lost over 5% of their body weight in the past year took part. Data were analysed using time series methods.

Main outcomes measures: Predictor variables were based on five theoretical themes: maintenance motives, self-regulation, personal resources, habits, and environmental influences. Dependent variables were: objectively estimated step count and weight, and self-reported WLM plan adherence.

Results: For all participants, daily fluctuations in self-reported adherence to their WLM plan were significantly associated with most of the explanatory variables, including maintenance motivation and satisfaction with outcomes, self-regulation, habit, and stable environment. Personal resources were not a consistent predictor of plan adherence.

Conclusion: This is the first study to assess theoretical predictions of WLM within individuals. WLM is a dynamic process including the interplay of motivation, self-regulation, habit, resources, and perceptions of environmental context. Individuals maintaining their weight have unique psychological profiles which could be accounted for in interventions.     

Habit and persistence

Voluntary behaviors (operants) can come in two varieties: Goal-directed actions, which are emitted based on the remembered value of the reinforcer, and habits, which are evoked by antecedent cues and performed without the reinforcer's value in active memory. The two are perhaps most clearly distinguished with the reinforcer-devaluation test: Goal-directed actions are suppressed when the reinforcer is separately devalued and responding is tested in extinction, and habitual behaviors are not. But what is the function of habit learning? Habits are often thought to be strong and unusually persistent. The present selective review examines this idea by asking whether habits identified by the reinforcer-devaluation test are more resistant to extinction, resistant to the effects of other contingency change, vulnerable to relapse, resistant to the weakening effects of context change, or permanently in place once they are learned. Surprisingly little evidence supports the idea that habits are permanent or more persistent. Habits are more context-specific than goal-directed actions are. Methods that make behavior persistent do not necessarily work by encouraging habit. The function of habit learning may not be to make a behavior strong or more persistent but to make it automatic and efficient in a particular context.
