Motivational Bias01:25

Motivational Bias

Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...
Motivational Cycle01:20

Motivational Cycle

The motivational cycle is a key concept that explains how individuals are motivated to meet their needs. At its core, the cycle revolves around four distinct stages: need, drive, goal-directed behavior, and goal achievement. These stages respond to imbalances in the body or mind, prompting actions that restore balance.
The cycle begins with a need. This need can arise from various conditions, such as hunger, thirst, or temperature changes. For instance, when an individual feels cold, their body...
Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Impression Management Techniques III: Aligning Actions

Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...
Drive-Reduction Theory: Push Theory of Motivation01:27

Drive-Reduction Theory: Push Theory of Motivation

Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or drive, pushes...
Impression Management Techniques IV: Altercasting01:14

Impression Management Techniques IV: Altercasting

Altercasting is a strategic communication technique in which an individual imposes a specific identity or social role onto another person to influence their behavior and shape the interaction. By presuming a role—such as “responsible leader” or “patient person”—altercasting encourages the target to conform to that identity, often aligning their behavior with the expectations associated with the role. The power of this tactic lies in its subtlety; once a role is assigned, it becomes socially...

Area of Science:

  • Human-Computer Interaction
  • Exercise Science
  • Behavioral Psychology

Background:

  • AI coaches are common in exercise, but how their features impact adherence is unclear.
  • Understanding the psychological mechanisms behind AI coach effectiveness is crucial for user engagement.
  • Voice anthropomorphism is a key AI design feature with potential links to user adherence.

Purpose of the Study:

  • To investigate if voice anthropomorphism in AI coaches influences exercise adherence.
  • To examine the mediating roles of trust, social presence, perceived coaching support, and self-efficacy.
  • To identify both linear and configurational pathways influencing adherence to AI coach-assisted exercise.

Main Methods:

  • Cross-sectional survey data from 572 users of AI coach-assisted exercise.
  • Partial Least Squares Structural Equation Modeling (PLS-SEM) for net relationship analysis.
  • Fuzzy-set Qualitative Comparative Analysis (fsQCA) for configurational pathway identification.

Main Results:

  • Voice anthropomorphism positively correlated with trust, social presence, and coaching support.
  • Trust, social presence, coaching support, and self-efficacy all positively influenced exercise adherence.
  • Coaching support had the strongest link to self-efficacy, which in turn most strongly predicted adherence.
  • Indirect effects via coaching support and self-efficacy were the most significant mediation pathways.

Conclusions:

  • Voice anthropomorphism is linked to exercise adherence through psychological mediators like trust and self-efficacy.
  • Exercise adherence is influenced by a combination of direct relationships and complex configurational pathways.
  • Findings highlight the importance of AI voice design and psychological support in promoting sustained exercise behavior.
