Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

119
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacodynamics in Geriatric Patients: Effects of Age

104
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Obedience

34.8K
According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

Eyewitness Memory01:22

Eyewitness Memory

323
Eyewitness memory refers to the recollection of events by someone who has directly witnessed them, often serving as critical evidence in legal settings. This type of memory is commonly used in criminal cases where a witness describes details like a suspect's appearance, clothing, or behavior during a crime. However, despite its perceived reliability, eyewitness memory is prone to significant errors.
One such error is memory distortion, which occurs because human memory does not function...

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

False Memories01:18

False Memories

258
False memories represent a cognitive distortion in which individuals recall events that did not happen, or remember them in an altered form. This phenomenon highlights the brain's constructive nature in processing and recalling memories, emphasizing that memory is not a perfect representation of past events but rather a dynamic reconstruction influenced by various factors.
One primary source of false memories is misattribution, where individuals incorrectly associate external information...

Summary
This summary is machine-generated.

Older adults exhibit higher interrogative suggestibility (IS), influenced by cognitive factors like memory. Age is a key predictor of IS, impacting response accuracy in questioning.

Area of Science:

  • Psychology
  • Gerontology
  • Forensic Psychology

Background:

  • Interrogative suggestibility (IS) is a key factor in legal questioning.
  • Understanding IS in older adults is crucial for fair legal processes.
  • Cognitive and emotional factors may influence IS in the elderly.

Purpose of the Study:

  • To investigate interrogative suggestibility in older adults.
  • To explore the association between IS and cognitive/emotive variables in the elderly.
  • To identify predictors of IS components (Yield and Shift) in aging populations.

Main Methods:

  • A sample of 172 participants was divided into three age groups: late adult (55-64), young elderly (65-74), and elderly (75+).
  • Cognitive (KBIT-2, RAVLT), emotive/affective (RSES, MCSDS, PSWQ), and suggestibility (GSS-2) measures were administered.
  • Statistical analyses included ANOVAs, Pearson correlations, moderation, hierarchical regression, and machine learning models.

Main Results:

  • Elderly participants showed the highest interrogative suggestibility across all indexes.
  • Age was the most significant predictor for both Yield and Shift components of IS.
  • Non-verbal intelligence and memory impairment were strongly associated with IS dimensions in older groups.

Conclusions:

  • Interrogative suggestibility significantly increases with age.
  • Cognitive functions, particularly non-verbal intelligence and memory, play a critical role in IS among older adults.
  • Findings have implications for adapting interrogation procedures for the elderly.
