Modeling in Therapy01:26

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Operant Conditioning Intervention01:24

Operant Conditioning Intervention

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
In operant conditioning, behaviors that are...
Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant factor...
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,...

Summary

A video role-modeling intervention briefly boosted postgraduate students' aspirations and effort during the Covid-19 pandemic. Sustained effectiveness requires careful consideration of timing and reinforcement.

Area of Science:

  • Educational Psychology
  • Behavioral Economics
  • Sociology of Education

Background:

  • The Covid-19 pandemic created unprecedented challenges for higher education.
  • Understanding factors influencing student aspirations and effort is crucial for academic success.
  • Aspiration-raising interventions may offer a pathway to support students.

Purpose of the Study:

  • To investigate the short-run effects of an aspiration-raising intervention on postgraduate students.
  • To examine the immediate and delayed impacts on aspirations and self-reported effort.
  • To assess the duration of these effects within the context of the Covid-19 pandemic.

Main Methods:

  • Randomized controlled trial (RCT) design.
  • Intervention involved a video-based role-modeling strategy.
  • Participants were postgraduate students at a UK university.
  • Data collected on aspirations and self-reported effort over a short period.

Main Results:

  • Suggestive evidence of an immediate increase in aspirations post-intervention.
  • Delayed increase observed in self-reported effort.
  • Both effects were temporary, dissipating within a few weeks.
  • Findings indicate limited short-term impact.

Conclusions:

  • Aspiration-raising interventions can have transient positive effects.
  • The timing and need for reinforcement are critical for sustained impact.
  • Further research is needed to develop long-term effective strategies for student aspiration and effort.
