The Availability Heuristic01:08

The Availability Heuristic

6.1K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Hindsight Biases

3.5K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Stereotype Threat and Self-fulfilling Prophecies02:09

Stereotype Threat and Self-fulfilling Prophecies

28.1K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Prediction Intervals01:03

Prediction Intervals

2.5K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Interference and Decay01:16

Interference and Decay

609
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Counterfactual Thinking01:19

Counterfactual Thinking

436
Counterfactual thinking is a cognitive process wherein individuals mentally reconstruct alternative versions of past events, often beginning with “what if” or “if only.” This reflective mechanism plays a significant role in shaping emotional experiences and guiding future behavior. Though typically triggered by unfavorable or unexpected outcomes, counterfactual thinking can also emerge in mundane, everyday decisions and experiences, revealing its deep entrenchment in...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Sleep Science

Background:

  • Neuropsychiatric symptoms and cognitive deficits impact time discrimination.
  • The relationship between sleep quality and time perception is not well understood.
  • Executive functions and attentional control are crucial for accurate time perception.

Purpose of the Study:

  • To investigate the impact of cognitive functions and sleep quality on time discrimination.
  • To explore differences in temporal bisection task (TBT) performance based on neuropsychiatric status.
  • To determine if stress, anxiety, or depression influence the point of subjective equality in time perception.

Main Methods:

  • Utilized the temporal bisection task (TBT) to assess time discrimination.
  • Collected data from 97 female participants (ages 20-72), resulting in 163 measurements.
  • Assessed neuropsychiatric status using Mini-Mental State Examination (MMSE), Frontal Assessment Battery (FAB), WHOQOL, Pittsburgh Sleep Quality Index (PSQI), and DASS-21.

Main Results:

  • Attention and executive control significantly influence time discrimination.
  • Better sleep quality correlates with improved time discrimination sensitivity.
  • Cognitive impairment, poor quality of life, and reduced sleep quality were associated with decreased time sensitivity.

Conclusions:

  • Cognitive functions, particularly attention and executive control, are critical for accurate time discrimination.
  • Sleep quality emerges as a significant factor influencing an individual's ability to discriminate time.
  • Findings highlight the interconnectedness of cognitive health, sleep, and temporal perception.
