Summary
Both visual discrimination and working memory tasks improved pain tolerance in children. Older children with better executive functions showed greater pain relief from distraction, suggesting cognitive load influences effectiveness.
Area of Science:
- Pediatric Psychology
- Pain Management
- Cognitive Neuroscience
Background:
- Distraction is a common pain management technique for children.
- The cognitive mechanisms, particularly executive functions, underlying distraction analgesia are not fully understood.
- Working memory engagement is hypothesized to be key in distraction's pain-attenuating effects.
Purpose of the Study:
- To investigate the role of executive functions, specifically working memory, in distraction-induced pain relief in children.
- To compare the effectiveness of a working memory task (1-back) versus a focused attention task (0-back) on pain tolerance.
- To examine how individual differences in executive functioning influence response to distraction.
Main Methods:
- Seventy-nine children (6-12 years) completed cold pressor trials with a visual discrimination (0-back) and a 1-back task.
- Executive functioning was assessed using the Wechsler Intelligence Scale for Children (5th Edition) and the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF®2).
- Tasks were administered in a counterbalanced order following a baseline trial.
Main Results:
- Pain tolerance increased significantly in both the visual discrimination and 1-back conditions.
- No significant difference in pain tolerance improvement was found between the two tasks.
- Age and executive functioning abilities moderated the response to distraction; older children with higher executive functioning showed greater improvements.
Conclusions:
- Both visual discrimination and working memory tasks effectively reduce acute pain in elementary-aged children.
- Executive functioning skills play a role in the efficacy of distraction analgesia.
- Further research is needed to optimize cognitive load and task difficulty for distraction interventions based on children's developing executive functions.

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

1.4K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

372
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.

01:23System of Memory
7.2K
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...
