Manipulating Belief in Free Will and Its Downstream Consequences: A Meta-Analysis

The longitudinal (in)stability and cognitive underpinnings of children's cheating behavior

There has been a long-standing debate about whether cheating is a stable behavior across various situations. However, there is a notable gap in our understanding about whether children's cheating behavior could exhibit stability over time. Moreover, research on the cognitive correlates of children's cheating is limited, yet exploring these cognitive factors is essential for understanding how children make (dis)honest decisions. This study aimed to test the longitudinal stability in children's cheating tendency and frequency and to explore the cognitive underpinnings of cheating behavior (theory of mind, inhibitory control, and free will belief). The study involved 100 children aged 3 to 6 years who were initially tested at Time 1, and 89 of these participants were retested at Time 2 approximately 1 year later. Cheating behavior was measured using a die-rolling game over Zoom, and three different cognitive abilities were measured. The results indicated that children's cheating tendency was stable over a year-long interval, whereas cheating frequency did not show longitudinal stability. Moreover, the study found that free will belief was related to cheating behavior, whereas theory of mind and inhibitory control were not. Specifically, children's belief in the free will to inhibit their desires, rather than their actual ability to inhibit the desires, was associated with a reduced frequency and likelihood of cheating. The findings can provide insight into the developmental origin of children's decisions to refrain from cheating.

Assessing the measurement invariance of Free Will and Determinism Plus scale across four languages: a registered report

Free will is assumed to be the core of an individual's self-concept. Belief in free will has been studied extensively and was found to be correlated with many behavioural and psychological outcomes. Although developed and validated in the West, the Free will and Determinism Plus (FAD-Plus) scale has been translated, used, and interpreted as a measurement of free will beliefs in multiple cultures. However, the cross-cultural measurement invariance of FAD-Plus has not been examined. Given the cultural differences in understanding the concept of 'free will', items of FAD-Plus may have different interpretations in different cultures, which may compromise its cross-cultural measurement invariance. To provide empirical evidence for the lack of cross-cultural measurement invariance, we collected data in China and analyzed these data together with open datasets of FAD-Plus in three other languages: Japanese, French and English. We only found partial measurement invariance between the Chinese and English datasets, as well as the Japanese and English datasets. These results provided the first assessment of cross-cultural measure invariance of FAD-Plus. We discussed the potential implications of the current study for future studies in the field.

Free will: An Example of the Dopaminergic System

Neuroscience has convinced people that much of their behavior is determined by causes unknown to them and beyond their control. However, are advances in neuroscience truly a prerequisite for such beliefs? Robert Kane's theory of ultimate responsibility is libertarian theory. Its innovative nature makes it possible to discuss the neurophysiological basis of its postulates. Using the functions of the midbrain dopaminergic system as an example, this article provides an overview of this neurophysiological basis. According to Kane, if we are to be ultimately responsible for our wills as well as for our actions, some actions in our lives must lack sufficient motives and causes. These are self-forming actions. Dopamine is hypothesized to mediate self-forming action execution. Dopamine not only mediates action but also ensures synaptic plasticity in the brain, that is, learning from action; hence, dopamine changes the acting individual and provides the formation of our own wills. The basal ganglia, which are the main target of dopamine in the brain, act through parallel pathways and are involved in decision-making processes. Dopamine is also involved in the regulation of the neurodynamical properties of prefrontal cortex networks with random spiking noise. It can be assumed that the activity of the dopaminergic system is closely related to the physiological basis of free will.

Free to be Healthy? Free Will Beliefs are Positively Associated With Health Behavior

Previous research has demonstrated that a stronger belief in free will contributes to a variety of socially desirable behaviors. We assessed the correlation between free will beliefs and health behaviors. Four studies (N = 1172) provide evidence that belief in free will is positively associated with health protective behaviors (e.g., physical activity, fruit and vegetable consumption, low fat diet) and negatively associated with health risk behaviors (e.g., alcohol consumption, smoking, unhealthy snacking). In relation to the respective health protective and health risk behaviors, we found free will beliefs were more strongly correlated with physical activity and alcohol consumption, respectively. We also found free will beliefs were associated with key social cognition determinants (e.g., attitude, subjective norm, perceived behavioral control, and intention). Overall, our results suggest that belief in free will can have important consequences for health behavior. This contributes to current theorizing about the implications of believing in free will.

Free from your experiences to grow: belief in free will moderates the relationship between attachment avoidance and personal growth initiative

BACKGROUND

Attachment theory proposes that attachment security facilitates personal growth. However, attachment security origins in relationship history, and thus, how people treat their experiences may influence the outcomes of attachment security. People differ in the degree in believing that human beings have free will, and belief in free will may influence the relationship between experiences and outcomes. The present cross-sectional study investigated the relationships between attachment security, belief in free will, and personal growth initiative.

METHODS

We used the cross-sectional data of 346 Chinese college students for data analysis, including correlational analyses, regression, and moderation analyses. The nine-item Chinese version of the Experiences in Close Relationships-Relationship Structures Scale, the sixteen-item Chinese version of the Personal Growth Initiative Scale-II, and the seven-item Free Will subscale of the Chinese version of the Free Will and Determinism Plus Scale were utilized.

RESULTS

Results showed attachment avoidance and belief in free will, not attachment anxiety, was associated with personal growth initiative. Belief in free will moderated the association between attachment avoidance and personal growth initiative. When the centered score of belief in free will was higher than 0.64, attachment avoidance was no longer associated with personal growth initiative. 85.84% of our data were below this Johnson-Neyman significance region, and 14.16% were above. In other words, only those who scored higher than 0.64 on free will beliefs were able to pursue personal growth despite their high attachment avoidance.

CONCLUSIONS

These findings suggest that when believing in free will, avoidantly attached people may believe in their ability to pursue personal growth and think their future has more possibilities, not influenced by other factors like social support, which they think they lack.

Does belief in free will influence biological motion perception?

Previous research suggests that belief in free will correlates with intentionality attribution. However, whether belief in free will is also related to more basic social processes is unknown. Based on evidence that biological motion contains intentionality cues that observers spontaneously extract, we investigate whether people who believe more in free will, or in related constructs, such as dualism and determinism, would be better at picking up such cues and therefore at detecting biological agents hidden in noise, or would be more inclined to detect intentionality cues and therefore to detect biological agents even when there are none. Signal detection theory was used to measure participants' ability to detect biological motion from scrambled background noise (d') and their response bias (c) in doing so. In two experiments, we found that belief in determinism and belief in dualism, but not belief in free will, were associated with biological motion perception. However, no causal effect was found when experimentally manipulating free will-related beliefs. In sum, our results show that biological motion perception, a low-level social process, is related to high-level beliefs about dualism and determinism.
